  What are Solar Shingles? Low-Profile Solar Panels for Homes

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  Among the most cited reasons that homeowners are wary of installing solar panels on their rooftops are their appearance.  Traditional photovoltaic (PV) solar panels are large, rectangular, blue-colored devices that some say decrease home values (one of the main complaints of homeowners associations that prohibit or restrict solar arrays).

  

  Low-profile solar shingles

  While the claim of lowered home values is untrue – its just the opposite, in fact – the appearance of solar panel systems can be improved with solar shingles.  Instead of their bulkier counterparts, new low-profile solar panels can literally blend into your roofing materials.  Also called building integrated photovoltaics, solar power shingles are designed to resemble roofing tiles so that your power generating materials blend right in.

  The leader in this new solar technology is Dow Chemical.  For years, we have been hearing about their solar shingles that would soon be available for homeowners.  The promises are finally coming true.

  Recently, CNET reported that Dow is now marketing its solar shingles, allowing homeowners to more easily install residential solar panels that have a sleek, unobtrusive appearance.  Solar cells created with Copper indium gallium selenide (CIGS) are printed onto a steel foil backing.

  Colorado was chosen as the testing ground for the new technology, with Dow selling solar shingles in January 2012.  Following the initial roll-out in Colorado, the company will move to California, and then Texas.  Eventually, you will be able to find the low-profile solar panels in 12 states over the next 18 months.

  Benefits of Solar LED Lighting

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  

  Solar LED lighting benefits

  Solar powered LED lighting is increasingly being used for street lights, residential lighting and even safety lights for construction, schools and other uses.

  There are several reasons that people are making the switch to solar LED lighting, because of its benefits:

  1.  LED lights use DC (Direct Current) Power

  When solar electricity is generated by panels, it is in the form of direct current (DC), rather than alternating current (AC) which is what you get when you plug into an electrical outlet.  Solar LED lights are especially efficient, compared to CFL or other lamps used in solar lighting because they do not require a converter.  This is because LED lights use DC power, which is the same as that which is generated by solar panels.  Any other type of lighting requires a converter before running on solar power, which results in a loss of energy.

  2.  LED Lights Have Better Light Output

  For solar lighting, use of LED lights have better light output.  They also can be used along the entire lighting spectrum, from bright blue-white to a soft warm glow.  Of course, LED lights come in clear (white) and colored lamps, which allow for creative applications ranging from holiday lights to solar garden lighting projects.

  3.  LED Lights are Brighter and More Visible

  This is my favorite feature of LED lights!  Not only are they brighter, which makes them more visible, even in daylight or foggy conditions, but they use less energy to burn so effectively (and efficiency).  Bright white LEDs have a superior CRI (color rendition index) for better illumination than traditional light bulbs.

  4. LED Lights Use Less Energy

  Solar LED lighting is a perfect fit because solar panels can easily generate enough power for their illumination.  Compared to CFLs, LEDs use 1/3 less power, and even less the energy required for incandescent lamps.  Because they are brighter and require less power, fewer LED street lights are required for the same amount of coverage, and municipalities and private property owners save money over time.

  5.  LED Lights Last Longer

  Solar panels last at least 25 years, so it only makes sense to use them with LED lights, as opposed to other types of lamps.  LEDs have at least a 10-year life expectancy, which is at least double that of halide or CFLs.  Solar LED lighting is a great example of install it and forget it when it comes to street lamps and other long-term light requirements.

  How Effective Are Solar Powered Cell Phones?

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  Any one that is a fan of portable solar power gadgets will love the idea of solar powered cell phones!  Manufacturers like Nokia are working to perfect the functioning of embedded solar panels within mobile phones to allow for on-the-go charging via sunlight.

  

  Nokia Solar Powered Cell Phone

  In fact, Nokia has been testing solar charging panels in its C1-02 devices in various settings around the world, from the Baltic Sea, to the plains in Africa and even deep in a Swedish forest.  What the cell phone manufacturer discovered was that the effectiveness of solar powered cell phones has less to do with location, than how they are used.

  People that pocket their phones and move around frequently during the day do not absorb as much solar energy as those that are more stationary and/or do not use their phones very often.  After its field tests, Nokia concluded:

  “Our test users proved beyond doubt that a low power mobile phone can stay functioning for long periods of time on solar energy. However, they also proved that your lifestyle and how you use a solar powered phone is as important as the environment, the weather and the time of year.”

  The bottom line is that solar powered cell phones are more effective for people that use their phones infrequently and allow them to absorb sunlight over extended periods of time.  In addition, cell phones with solar panels may be most practical in sunny regions, particularly those in remote areas not reached by the grid.

  Research and development continues.  As solar cells become more efficient in converting UV light to energy, we could soon see solar mobile phones that are practical for many uses in more and more areas of the world.

  States With the Cheapest Solar Power

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  

  How affordable is solar power in your state?

  The price of solar energy is not the same across the United States.  Among other things, state incentives for solar, localized costs, and marketplace competition varies.  The amount you can save by switching to solar power also depends on the price of grid-based electricity, in terms of kilowatt hours.  States with expensive electricity – New York and California – may indirectly encourage homeowners to go solar to slash utility bills.

  

  Top 20 States for Cheap Solar Power

  By installing residential solar panels, you can expect to cut energy bills by 50% or more.

  If you are wondering which are the states with the cheapest solar power, take a look at the list of the top 20, based on the Q3 2010 report from U.S. Solar Market Insight (published by the Solar Energy Industries Association and GTM Research), shown to the left.

  Colorado tops the list of states for cheap solar power with an average installed price of $5.90 per watt.  In last place is Wisconsin, with solar PV installations costing $7.55 per watt.

  In the middle of the list are solar powerhouse states, including California and New Jersey, with $6.71 and $6.75 per watt.  In New York, homeowners pay an average of $7.10 per watt for solar power.

  If your state does not show up on the list of the top 20 states with the cheapest solar power, don’t take that as an indication solar is an unwise investment.  In fact, its just the opposite!

  Prices for solar panels are continuing to fall, while efficiencies increase.  Grid parity – the point at which solar power is no more expensive than fossil-fuel based electricity has already arrived in Hawaii and is on the near horizon in other states, too.

  By installing solar panels, you can immediately start saving on your utility bills and guard against future utility rate hikes.  This is the case in these top 20 states, and the remaining 30 in the nation!

  5 Easy Ways to Save Money on Solar Panels

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  Many homeowners who are considering – or want to consider – installing solar panels are concerned most about the upfront cost of such a project.  Fortunately, there are many ways you can save money on solar panels today.  You don’t have to pay full retail price, or even put money down in some cases.

  

  Save Money on Solar Panels

  Here’s how you can afford going solar this year:

  1.  Lease Solar Panels

  Instead of owning the solar array yourself, you enter into a contract with a solar company that will install, own and maintain the installation on your rooftop.  When you lease solar panels, you only pay a fixed monthly cost for the electricity generated by the panels.  Not only is the amount less than what you would otherwise pay your utility company, but it is green energy (help save the environment) and you guard against utility rate hikes during the life of your lease (20-30 years).

  2.  Negotiate a Group Discount

  We’ve blogged about solar panel group buying services such as those provided by One Block Off the Grid (1BOG).  Enter your zipcode at the website and they will let you know if other homeowners in your area are also considering going solar.  Then, 1BOG will negotiate a group discount for all those interested, which can save you 20% off retail.

  3.  Look into Financing for Solar Panels

  Solar panels are considered to be a good investment, not only by homeowners, but also by various contractors, financial institutions and banks that offer financing for solar arrays and home equity loans for energy efficiency projects, at discounted interest rates.

  4.  Tax Credits and Incentives

  This one is practically a no-brainer.  Solar tax credits, rebates and incentives are offered in every state, as well as the federal government.  The federal tax credit allows up to 30% of solar panel installation costs.  Coupled with state or local rebates, you can save as much as 80% off the cost of solar power.

  5.  Solar Renewable Energy Credit

  Most states in the U.S. allow homeowners to add onto the power bill savings they enjoy each month with solar panels through Solar Renewable Energy Credits (SREC).  The program works by giving financial credit for each megawatt-hour of electricity generated by the owner’s residential solar power system.  Depending on the individual state’s program, SRECs are basically a financial instrument, sold to utilities or solar energy markets.  People with home solar panels can expect credits of $200-700 a year, which is a nice bonus to lower power bills!

  Spray on Solar Cells Advantages

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  

  Spray on solar cells

  Spray on solar cells are one of the more exciting solar technologies that can be employed as building integrated photovoltaics.

  Thin film solar is incorporated into solar inks that can literally be painted onto walls and windows of structures allowing the sides of buildings to function as solar collectors to generate enough electricity to power interior uses.

  Unlike bulky photovoltaic (PV) solar panels, spray on solar cells use thin film nano particles instead of silicon as solar conductors.

  Applied to the sides of structures that face the sun, the thin solar cells invisibly generate clean, green power.

  Spray on solar is not limited to buildings, either.  Thin film solar technology is also used in clothing, and may one day be incorporated into automobile paint.

  Advantages of Spray on Solar Cells
  

  • More efficient than conventional solar panels
  • Capable of generating ample electricity
  • Hassle-free installation of solar technology
  • Able to harness even infrared rays from the sun, allowing generation of solar power even on cloudy days

  Top 5 States for Residential Solar Panel Installations

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  

  Residential solar panel installation

  Solar power is picking up across the United States with more and more people installing solar panels for energy independence and to reduce their carbon footprint.

  Although residents of any state can find bargains and incentives on solar arrays, the top 5 states for residential solar panel installations (as of the date of this post) include:

  • California
  • Arizona
  • New Jersey
  • Colorado
  • Pennsylvania

  According to a SEIA/GTM Research report, these five states offered very favorable markets for residential solar installations in 2010.  As a result, they represent the greatest megawatts of solar electricity capacity installed.

  The State of California boasted nearly 128 MW of capacity from residential solar panel installations in 2010.  The remaining states on the top 5 list had a range of 14-28 MW of installed solar power that year.

  So what were the driving forces that encouraged so many people in these states to install residential solar panels?

  First, homeowners are able to go solar without the upfront costs with a solar panel lease – where the system is owned and maintained by a solar manufacturer – or a solar power purchase agreement (PPA), in which a homeowner contracts to buy solar power at a competitive fixed rate over for 10-20 years.

  These financing options are provided by companies including, but not limited to Sungevity, SolarCity, SunRun and SunPower. In 2010, as many as 30% or more of residential solar systems were installed with a lease or PPA in states where these financing options were readily available.

  Second, these states offered generous, aggressive incentives to install residential solar panels.  Investment in solar by homeowners is encouraged with rebates, tax incentives and SREC programs. Each of the top five states provides at least one of these options.

  Bottom line, the top 5 states for residential solar panel installations have programs and incentives that reduce (or eliminate) the upfront cost of switching to solar power.  Over time, homeowners save significant money in utility bills and gain security against rising utility costs.  Of course, solar power is cleaner than fossil-fuel based electricity.

  Hopefully, more states will join these five in increasing solar capacity in 2012.

  Removing Snow from Solar Panels

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  

  How to remove snow from solar panels

  While it may not seem like winter yet across much of North America, you should still know how to remove snow from solar panels when Old Man Winter finally arrives.

  Snow-covered solar panels are less efficient because they are obscured from sunlight. Removing snow from solar panels must be done carefully so as to avoid damaging your investment.

  Here are 8 ways to do so:

  1. Sweep or Rake Snow from Solar Panels. This method works best with dry, powdery snow.  Heavy, wet snow is more difficult to remove.  With a ladder to reach your rooftop, use a push broom to carefully move snow from the panels.  You can also invest in a roof rake at RoofRake.Com.

  2. Install your Solar Panels on racks at a 35-degree angle. Angling the position of your solar panels will not only help you maximize efficiency, but can also help keep snow off your solar array.  With a greater tilt, snow will more easily slide off, instead of accumulating.

  3. Melt snow with blowing air. Some creative homeowners remove snow from solar panels using a leaf blower with PVC pipes or plastic air hoses.  Warm air directed at or under the solar panels can melt the snow, or simply blow the snow away (again, this works best if it is dry, light snow) with such a system.

  

  A broom or rake can be used to remove snow from solar panels

  4. Use a soft ball to break up accumulations. Have your kids help you remove snow from your solar panels!  By tossing a Nerf ball, or other soft non-damaging ball at the panels, you can break up accumulations and speed up the melting process.

  5. Try an ice melt sock. This is a DIY snow removal system tat requires using calcium chloride in a sock, which is placed at the top of your solar panels.  The chemicals accelerate snow melt.

  6. Use Heat tape. Some homeowners have had success removing snow from solar panels using heat tape applied to the sides and top of the rooftop array.

  7. Spray off Snow with a Garden Hose.  If the temps are above freezing, one of the simplest solutions is to spray the snow off your solar panels with a garden hose.  Quick, safe and effective!

  8.  Set up a tarp before the storm. With advance forecasting, you can set up your solar panels to allow for easy snow removal by covering them with a tarp.  With a pulley system, you can then simply pull the tarp down, removing all the snow in one easy step.

  Bringing Solar Power and Electricity to Third World Regions

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  We have published a number of articles on the benefits of solar power for Third World countries.  Many of these regions are so far from grid-based electricity that the International Energy Agency estimates that half of those currently living without electricity (about 1.2 billion people) will never be reached by the grid.

  

  Third World regions benefit from solar power

  This means that distributed generation solar power (produced and consumed on the same site) is key to bringing inhabitants of Third World regions the necessary advancements they need for health, safety and quality of life.   In other words, power plants likely will never serve these people.  They need solar panels installed in their villages so that the renewable energy resources can be tapped locally.

  Why is it Important to Bring Solar to Third World Regions? 1.  Cost of Lighting

  Kerosene and candles are often the only means of lighting living spaces in certain areas of the world.  Yet, they are disproportionately expensive for the impoverished people that rely on them.  One statistic states that the poorest fifth of the world pays one-fifth of the world’s lighting bill — but receives only .1 percent of the lighting benefits.  The cost of this energy is about $180/year, adding up to nearly $2000 over a decade.  The cost of kerosene depletes 25-30% of a poor family’s income.

  Instead of kerosene and candles, a 40 watt home solar power system can be purchased for only $300 and will provide not only lighting, but also electricity to charge cell phones, run fans and power other electronic devices like computers and TVs.

  2.  Environmental Safety

  Use of kerosene is unhealthy and unsafe.  Lighting a room with a kerosene lamp can result in an increase in indoor pollution by ten-fold.  Each year about 1.5 million people die from this exposure.  When the lamps tip over, fires often start, harming or killing even more people each year.

  3.  Health Reasons

  Living off-grid, without traditional power sources, people in Third World countries often lack the ability to keep medications sufficiently chilled or food maintained at a safe temperature.  Electric refrigerators run on solar power can be a significant improvement in the quality of life.

  How can we Bring Solar Power and Electricity to Third World Regions?

  While the use of solar power by people in developing regions can vastly improve their lives, they do not have the funds up front to invest in the renewable energy resource.  In order to help bring distributed solar energy to the approximately 1.2 billion people who live off grid, experts agree that we need: (1) up front investment capital for the cost of solar panels and installation; (2) a way to recoup the annual cost of solar electricity generated by the installed systems (much less than the cost of kerosene); and (3) networks/partnerships to actually bring the solar panel systems to Third World regions.

  With the cost of solar panels having dropped dramatically over the past few years, the resource is much more affordable for everyone.  Not only does that improve the prospects of bringing solar power to developing regions, but the overall health of the planet stands to benefit.  The annual carbon emissions from kerosene lighting is the equivalent of the greenhouse gases put out each year by the entire British economy!

  In short, helping to bring solar to Third World countries will be life-changing for the people that live there, and the entire world.

  Oregonians Should Resolve to Go Solar in 2012

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  

  Oregon solar panels

  Here in my home state of Oregon, the number of home solar power systems have tripled in the past 3 years. In fact, more than 2/3 of all existing solar installations in Oregon have taken place since 2008.  If you haven’t already done so, isn’t it time to resolve to go solar in 2012?

  The massive growth in the number of operating solar panels in Oregon is due in large part to lowering solar prices, rising energy costs and generous incentives from the Energy Trust of Oregon which, in addition to state and federal tax credits, can lower the cost of residential solar power systems by 80%!

  If you resolve to go solar in 2012, what should you consider?

  1.  Does your property have ample sunlight exposure?

  2.  What are your monthly and annual electricity costs?

  3.  What tax credits and incentives are you eligible for?

  4.  Does your utility offer net metering for grid-tied solar panel systems?

  5.  Are you interested in solar electricity, solar hot water, or both?

  6.  Do you wish to purchase or lease solar panels?

  Even if you are not eligible for certain solar incentives, many people find that government tax credits can save them thousands of dollars in the cost of solar panels, in addition to significantly reduced (if not eliminated) utility bills.  Not to mention the fact that utility rates rise each year, while the price of solar electricity stays the same -FREE!

  The average cost of solar panels for a residential Oregonian home is $16,000-20,000 before incentives.  Such a solar panel system will cover about 300 square feet of rooftop space and generate 25% or more of a property’s electricity needs, depending on energy efficiency measures.

  Oregonians can find out more about solar power options for their home or business by contacting the Energy Trust at 866-368-7878 or visiting its website: www.energytrust.org.

  Solar Panels installed on a Bainbridge Island, WA Habitat for Humanity house

  One of the things on my bucket list is to help build Habitat for Humanity homes.  Now, these community-built, free structures can be even cheaper to live in when they include solar panels.

  In Dallas, Texas and Phoenix, Arizona (among other cities), solar panels on Habitat for Humanity homes are available via donation and installation of solar arrays from a number of companies.

  Solar panel companies often donate arrays for installation on Habitat for Humanity homes.  Not only will the solar panels help save cash-strapped homeowners money, but they also reduce the carbon footprint of the home’s occupants as a result of using clean, free solar power, rather than coal or natural gas for electricity.

  Over a 12-month period, the owner of a Habitat for Humanity house with solar panels can save nearly $1000 and watch their power bills drop to only $30 per month!

  Solar Power Benefits Third World Countries

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  

  Solar power benefits Third World Countries

  For developing regions in Third World countries, many of life’s basic necessities are difficult to achieve due to poverty and/or living far from the electrical grid.  Keeping medical supplies at cool temperatures via refrigeration, making emergency telephone calls, lighting living spaces in a safe manner, and even purifying water and cooking food can be challenging, if not impossible.

  Using solar power benefits Third World countries because the resource is ample and inexpensive.  Consider this startling fact: Africa has 9 times the solar energy potential of Europe—an annual equivalent of 100 million tons of oil.  If even a fraction of this solar power was tapped into, impoverished countries could even boost their economies by selling excess solar electricity to European countries.

  In recognition of the value of solar power to developing countries, Sunbelt International recently announced an initiative to aggressively develop and deploy solar energy technologies and systems in third world countries. According to Sunbelt International President Fang Soo Lui:

  “It is the strategic objective of Sunbelt International to approach emerging markets with sustainable energy alternatives.”

  Sunbelt will work with a number of developing nations to install the solar power units.

  In addition to Sunbelt’s new initiative, the World Bank announced last year that a $5.5 billion package would be invested in utility scale solar power plants in Africa.  One of its goals was to encourage additional private investments and entrepreneurs.

  With solar power projects in Africa, CO2 emissions can be reduced by 740 million tons annually.  And that is a benefit that can be enjoyed by the entire world!

  Net Metering for Grid-Tied Solar Power Systems

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  

  Illustration of net metering

  While it is possible to go entirely off-grid with solar panels, most people considering residential solar want grid-tied solar power systems.

  Summarized briefly, net metering benefits both the property owner and the utility company.  If you have solar panels installed and generate more electricity than you require, the excess is fed back into the grid for use by other consumers.  The utility will give you a credit against any power you need to draw from the grid at other times, at a specific, agreed rate per kilowatt-hour (kWh).  Some people even get a refund if they end up producing more power with their solar panels than they use any given month.

  Net metering for grid-tied solar power systems also benefits the power company because they are provided with additional electricity that they can sell, often at peak demand periods.  Perhaps not surprisingly, a net metering arrangement usually involves the utility paying you slightly less for the power than the rate at which they will charge other consumers.

  Net metering is regulated on a state-by-state and/or local basis – there are not any national standards yet.

  Its easy to use net metering with home solar power systems, but be sure to check with your utility provider regarding rates and details of the arrangement.  All you need is a net metering monitor to be installed with a grid-tied solar power system.  The device will track your use of grid-tied power, which is compared to the amount of energy produced by your residential solar array.  You can also review data regarding the dates and times of peak or low power usage.

  The US Energy Policy Act of 2006 requires utilities to provide each residential and commercial energy user with net metering. With a solar power system, you can save substantial amounts of money by generating power during the day (peak demand times) and only drawing on the grid overnight when energy demands are lower.  Overall, you can end up with inexpensive, affordable power with tiny, if not nonexistent, electricity bills!

  Portable Solar Panels: Flexible Solar Power

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  Portable solar panels are the answer to two of the more pressing issues these days: (1) keeping electronic gadgets charged up, and (2) saving money and greenhouse gas emissions for the energy required.

  Electronic devices like cell phones, cameras, mP3 players and computers require a lot of power to recharge.  Using solar panels is becoming a more mainstream way to keep charged up without the need for an electrical outlet.

  

  Portable Solar Power to Recharge Devices

  Today, you can find portable solar panel devices to recharge electrical gadgets using ultraviolet light.  And the newest version of portable solar panels is flexible solar power using thin film solar technology.

  Here are two new products for portable solar panels that use flexible solar power:

  1.  SolarRoll is comprised of PV (photovoltaic) cells and can be rolled and carried in a small backpack. It produces up to 14W of electricity for recharging small devices like cell phones and digital cameras.  SolarRoll is useful for people who spend a lot of time outside, including fishers, hunters, hikers and more. The device is also weather proof, and UV transparent. It costs in a range of $199-$479.

  2.  Suntrica is another flexible device that uses solar energy for recharging gadgets.   It is so convenient, you can fit it into your pocket.  The thin film solar technology absorbs UV light and converts it into solar energy to recharge portable devices.

  Do you use portable solar panels and/or flexible solar power to recharge mobile devices?  Let us know in the comments below!

  Solar panels on apartment buildings

  Solar panels on low-income housing provide a win-win for residents and other people in the local economy.

  Here in the Central Oregon region in which I live, $900,000 in federal stimulus funds is helping fund solar power systems for several low-income housing apartment complexes.  The Energy Trust of Oregon is also committing funds toward the projects.

  The Oregon Housing and Community Services Department is the agency through which federal funding is passed to local agencies to fund experimental solar panels, energy monitoring systems and high efficiency HVAC systems.

  Not only will the solar panels help people save on their monthly electricity bill, but the project will provide much needed jobs for installers.  In Madras, Oregon – a community near the Warm Springs Indian Reservation, solar panels will be installed at Madras Townhomes.  In addition, residents at Healy Heights apartments in Bend, Oregon will soon enjoy free solar electricity generated by nine solar arrays installed on the complex’s rooftop.  The solar panels will generate approximately 170,000 kilowatt hours (kWh) annually, saving each resident about $250 per year.

  It goes without saying that the residents of low-income housing would not otherwise be able to afford residential solar panels for themselves. By funding solar panels for low-income housing residents, the money saved on energy bills can be put toward food or warm clothing, instead.

  The solar panels in low-income housing in Central Oregon are being installed by E2 Solar.

  Solar Powered Travel

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  Many people are looking to travel with a lighter carbon footprint.  Green travel tips, eco-friendly hotels and more are springing up faster than daffodils in Spring.  Its time to add solar powered travel to the list!

  

  Solar powered travel in an RV

  Next to staying at home, traveling in an RV (recreational vehicle) or boat is one of the greenest options around.

  You might be surprised, but the minimal amount of power required, the often small/compact spaces, and the fact that you probably are not washing and drying linens every day greatly reduces energy use when you are on the road.  Adding solar panels to your RV or boat can help you avoid running a gas generator or drawing on other fossil-fuel based power.

  Portable solar panels are relatively inexpensive and easy to install when they come as part of a solar power kit:

  You can be on the road (so to speak) toward solar powered travel after just a weekend of set-up.  Solar panels can be installed on the roof of an RV or boat in order to absorb sunlight, generating clean, free electricity to recharge batteries and run appliances.  If you are away from shore for days, marine solar panels are especially useful to keep batteries charged so you can relax and enjoy your excursion.

  Prices for solar power kits range from $299-3999, depending on your power needs and the size of array required.

  Tags:    [edit]

  

  Smartbox Solar from Clarian is a plug in solar panel

  Let’s face it – two considerations usually stop people from seriously considering a switch to home solar: (1) the price; and (2) the hassle of installation.

  That’s why plug in solar power from Clarian, known as Smartbox Solar is an excellent alternative.  Within minutes, you can start generating solar power with plug in solar.  No need for wiring or expensive installations.  Simply plug in the 200W solar module into an existing outlet, just as you would any other home appliance.

  The only question you’ll have to ask concerns placement of the Smart box Solar  – whether on a shed, window overhang or porch cover.  Placement near an existing outlet is required, as well.

  One of the other benefits of plug in solar power is that you don’t need to purchase a solar inverter.  If you wish to generate more solar energy, you can purchase additional modules.

  While Clarian has not yet released Smartbox Solar for retail sales, the website states that the cost will be about the same as a refrigerator or other appliance.  Savings can add up to repay the cost within 5 to 8 years, including renewable energy rebates or tax credits.  A single 200W plug in solar power module can generate enough energy to offset costs of lighting your home each year.

  Solar panels provide clean solar electricity for Purdy Farms Christmas tree lots

  So, after considering whether to go with a real or fake Christmas tree, its time to head to the tree lot.  Did you know that in San Diego, the lights and chainsaws used at the Purdy Farms Christmas Tree lots are solar powered?  Stellar Solar has provided a mobile solar station that includes giant photovoltaic (PV) solar panels to generate clean, green solar electricity to light up the Christmas tree lots and keep things going throughout the holiday season.

  Last year was the first season that Stellar Solar helped create the solar powered Christmas tree lots.  The hope is that more tree farms and retailers will consider solar power for their holiday lighting needs this year and in the future.

  Kent Harle, founder and President of Stellar Solar, commented:

  “We are always looking for innovative ways to utilize our Mobile Solar Station. Powering the Purdy Christmas tree lots is a great way to do that in a unique location and expose a whole new audience to the practical use of solar power. It makes sense given that they used solar power to grow these trees in the first place.”

  Portable solar power such as Stellar Solar’s mobile solar station is increasingly used for operations such as home construction and military operations.  How perfect that it is also well suited for short term commercial requirements like Christmas tree lots?

  How to Choose a Solar Panel Installer

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  Going with solar panels?  Great!  Before long, you’ll be saying goodbye to your high electricity bills and enjoying free solar power, as well as the security of knowing that your utility rates will not rise.  But before your switch to solar, you’ll need to learn how to choose a solar panel installer.

  

  Solar panel installers

  Consider these tips and then schedule an appointment to get a solar power estimate:

  1.  Get multiple estimates.  Ask for at least 3 solar estimates so you can compare and contrast the professionals that may be installing a 35-year investment on your home rooftop.

  2.  Compare low vs. high-priced solar installers.  Ask why the professionals you are considering are charging their rates, whether based on material costs or experience.  Remember that you often get what you pay for – so a bargain-basement solar panel installer may not be what you want long term.  On the other hand, a professional that seems to be charging exorbitant fees may not be worth the price in the end.  Ask around and read reviews, if available.

  3.  What does your Gut Instinct Say? Sometimes you have a feeling right from the start before you even hire a professional for home improvement or repair.  Perhaps its based on recommendations or reviews, or maybe just an impression that this person really understands their profession, answers questions well and more.  If so, go with them!  Do make sure, however, that they are certified and licensed.

  Do you have any of your own tips for choosing a solar panel installer?  Please share in the comments below.

  Residential Solar: 5 Things You Should Know

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  

  Installing home solar panels

  For homeowners considering installing solar panels, there are 5 things you should know about residential solar.  As more and more people decide to switch to renewable energy options like solar power, keep these considerations in mind:

  1.  You may be eligible for group solar discounts.  Before you enter into a contract to install home solar panels, check out sites like One Block Off the Grid, which may be able to secure a group discount for you and other homeowners in your neighborhood or region.

  2.  Residential solar panels improve the value of your home.  Despite concerns about the initial investment associated with solar panels, you can recoup the costs both in lower energy bills and an increase in $20 of home equity for every $1 you save in annual electricity bills.

  3. A solar home is more affordable today than two years ago.  Solar panel prices have fallen dramatically in recent years.  Experts predict that the costs will continue to decline as we approach grid parity – the point at which solar power is as affordable as coal.

  4.  Solar tax incentives and rebates may be ending soon.  In just a few years, if not earlier, federal solar incentives and rebates that allow you to save 30% may end in the U.S.  If you are thinking about solar power, now is the time!  Solar rebates and tax incentives will not last forever.

  5.  Low profile solar panels via solar shingles help minimize aesthetic impacts.  If you would like to install solar panels but are worried about the impact on the appearance of your home, solar power shingles may be your answer.  They look like regular asphalt shingles, but generate clean solar electricity like their bulky photovoltaic (PV) panel counterparts!

  Residential solar is becoming mainstream as more homeowners realize the savings they can recoup by going solar.

  If you are considering making the switch, what considerations are on your mind?

  Demand for Solar Power Continues to Grow

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  Despite the failure of Solyndra and the relatively small sector of people who still deny global climate change, demand for solar power continues to grow.  Solar is inexpensive, clean renewable energy, and is poised to overtake dirty sources of power, like coal in the next few decades (if not earlier).

  

  Demand for solar power will continue to grow

  Solar power is superior to gas and coal not only from an environmental standpoint, but also on the basis of national security.  Instead of drilling, shipping and refining fossil fuels from foreign nations, we can simply harvest free solar electricity from the sky!  Not only that, but the cost of solar panels has fallen dramatically in recent years, making this energy resource clean and cheap!

  In recent years, the number of solar panels produced has increased in part to help drive demand and drop prices so that solar is inexpensive enough to penetrate world energy markets.  As a result, China and India have both projected significant solar installations in the coming years.

  China has increased solar installation plans from about 1 gigawatt (GW) today, to 10 gigawatts by 2015.  From there, the country is aiming for 50 gigawatts by 2020!  China plans to lead the world in solar production as well as installed capacity.  India is also planning meteoric solar capacity growth, from 54 megawatts (MW) in 2010 to 9 gigawatts by 2016.  From 2016-2020, the country plans to more than double solar installations to 20 gigawatts.

  To put this into perspective, a single gigawatt of solar power is the equivalent of about 3,000 acres of solar panels!

  Compared to China and India, where does the U.S. stand on solar power capacity?  Currently, the country has about 2.7 gigawatts installed.  But with prices falling, the Solar Energy Industries Association believes that about 10 GW of new solar capacity will be added each year by 2020.  That means that, here in the U.S., we will comprise most of the 70% annual increase in global solar production capacity.

  In short, solar is America’s single fastest growing industry.

  Switch to Solar Electricity or Solar Hot Water: What Would You Do?

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  

  Solar electricity or solar hot water?

  If you are thinking about installing a solar panel system on your home, you may be wondering whether solar electricity or solar hot water is the way to go.  There are probably several factors that you are thinking about:

  • Cost
  • Efficiency
  • Appearance
  • Return on investment
  • Energy savings
  • Tax rebates and incentives

  Comparing solar electricity (photovoltaic, or PV panels) to solar hot water systems, you can stand to save a lot of money with both.  In general, solar photovoltaic panels generate electricity for use throughout your home.  Using PV panels, you draw less on the grid and pay less to your electrical utility.  On the other hand, solar thermal panels save you money on the energy required to heat water for domestic use – bathing, washing dishes, laundry and more.

  Here is a brief introduction to solar hot water:

  For homeowners considering solar, solar hot water is less expensive than solar electricity systems.  In fact, many people make the switch to solar by going with solar thermal panels, rather than PV panels.  As a result, the return on investment for solar hot water is shorter than for traditional solar panels (5-8 years, compared to 10-15 years).

  On the other hand, solar PV panels can save you significantly more money and energy over the life of a system.  Plus, with grid-tied systems, you can get credit on your utility bill for excess solar power generated via net metering.  Because all water heated with a solar hot water system is used on-site, there is no opportunity to extend your savings by selling excess solar-heated water to your community.

  There are currently more options for financing solar PV panels than solar hot water systems, including solar panel leasing.  But both types of solar panels boost the value of your home and help you reduce your carbon footprint, while saving you money on your monthly utility bills.

  So – whether you switch to solar electricity or solar hot water, you’re making a smart investment.  What would you do?

  Solar Incentives Not Sunshine Lead to Solar Panel Installations

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  

  Solar incentives encourage solar panel installations

  Ever wonder why there is such a big difference in solar panel installations between two of the sunniest states in the U.S. – California and Florida?  Property owners in California account for over 50% of the country’s solar power, while Floridians generate only 1%.  Meanwhile, the State of New Jersey is the second highest in the nation when it comes to solar energy.

  The reason is that solar incentives, not sunshine, encourage people to go solar.  Incentives in the form of tax rebates, property assessed clean energy loans (financing solar panels through property tax programs), and more result in greater numbers of solar panel installations.  Add to these programs an overall “climate” – if you will – in favor of clean energy and environmentalism that is embraced by state lawmakers, and solar can thrive in just about any location.

  Solar incentives in California tell a great deal of the story:

  • Governor Arnold Schwarzenegger initiated a $3.3 billion dollar Million Solar Roofs program, with the goal of producing 3,000 new megawatts of solar power by 2017.

  • The California Energy Commission’s New Solar Homes Partnership encourages construction of new homes with residential solar through a 10-year, $400 million dollar program.

  • The California Public Utilities Commission’s California Solar Initiative provides additional incentives for solar panel installations.

  For homeowners looking for solar incentives, check where your state rates on the Database of State Incentives for Renewables and Efficiency.  Contact a solar contractor to help you pencil out your potential savings through solar panels, and don’t forget to factor in the boost in property value you’ll enjoy as a result.

  Free Home Solar Systems: Do You Qualify?

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  Did you know that you might be eligible for free home solar systems if you are a California resident?

  

  Free home solar system to qualified homeowners in California

  That’s right!  A state program administered by the California Public Utilities Commission allows low-income California residents to go solar without worrying about the cost.  Lest you think that the program is just a gimmick, switching to solar power helps the participants lower electricity bills and save money!

  California’s free home solar system is through its Generating Renewable Ideas for Development Alternatives (GRID Alternatives) program.  Its purpose is to bring solar power to low-income homeowners, in part to protect them against rising, uncertain utility rates in the future.  The program is available through funds invested by utilities, private corporations and non-profit organizations, as well as through a public benefit fee paid by public utility customers.  The GRID program is part of Single-Family Affordable Solar Homes (SASH).

  

  Install home solar panels

  Grants and loans are used to fund GRID residential solar power projects.  The program allows a free 1-kilowatt solar system for homeowners earning less than 50% of their region’s median family income, per the U.S. Department of Housing and Urban Development.  If you do not fall below that line, no worries.  Those that earn between 50-80% of median income can enjoy generous solar rebates between $4.75 to $7.00 per watt, which is a practically free home solar system.  In addition to income requirements, homeowners must occupy the residence for which they desire solar panels, and the home must be served by Pacific Gas and Electric, Southern California Edison or San Diego Gas and Electric.

  Save More Energy With Solar Hot Water

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  Solar power panels can help you save money and energy.  But did you know you can save more energy with solar hot water, too?

  Solar hot water, also known as solar thermal systems (or solar thermal panels), use energy from the sun to heat water for domestic uses without the need for electricity.  For homes and commercial operations that require heated water, a solar thermal system could be just the thing to help significantly trim monthly expenses.

  

  Solar thermal collectors

  Once you have a solar hot water system and are not paying for electricity to heat your water, let’s talk about saving even more energy and money.  How can you do that?  By using less hot water, of course!

  1.  Go with low-flow shower heads.  A nice hot shower is relaxing, but let’s talk about saving water and energy!  Today’s low-flow models are so efficient and advanced, you might not even believe you are saving money.

  2.  Reduce the thermostat on  your hot water tank.  Whether you have young children or not, turn down the maximum heat for your hot water.  A few degrees lower will use significantly less energy over a month or a year.

  3.  Use hot water during off-peak periods.  Demands for electricity, and hot water, are highest at the beginning and end of the day.  If possible, delay your shower until mid-day (maybe go to work until noon, then exercise and shower afterward?).  Set your dishwasher and washing machine on a delay setting, and wait until you arrive home in early evening to start your appliances.

  Solar thermal systems generally work as follows:  Sunlight heats glycol (an antifreeze solution) in the panels’ tubing.  The tubing is connected to a hot water tank with a pump that circulates the glycol to heat the water throughout the system.  As water is drained from your hot water tank, new solar hot water is replaced/pumped into the tank.

  Solar thermal panels work, regardless of whether you have bright sunlight.  Even a cloudy day offers enough light to create heat for a solar hot water system!

  Five Reasons You Should Install Solar

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  Should you go solar?  Have you been thinking about solar power for your home?

  

  Reasons to install solar panels on your home

  Like many people, you probably want to save on your utility bills.  You might even want to reduce your carbon emissions by using less grid-based electricity (generated from burning coal or natural gas).  You can do both!

  Residential solar panels are more affordable than ever today.  Let’s get started! Here are five reasons you should install solar:

  1.  Solar panels have dramatically dropped in price over the past few years.  An average-sized American home would require a solar power array at a retail cost of $30,000.  In 2009, the same system would have cost nearly $50,000.  Take into consideration the fact that federal and local incentives and rebates can slice off another $10,000-15,000, and the investment makes sense.  If you don’t want to buy, you can always lease solar panels with no money down.

  2.  Solar panels boost the value of your home.  For every $1 you save on annual electricity costs, the value of your home increases about $20.  Average American homes use about $130 of grid-based electricity each month.  If you slice off $100 a month, for an annual savings of $1200, you just got an instant boost of $24,000 in home equity.  Not too shabby in this market!

  3.  Solar panels help your home sell faster when you put it on the market.  Homebuyers are looking for valuable improvements.  If you have taken the time to invest in and install solar panels, a potential buyer will recognize that they will instantly have monthly savings of about $100. A study by the National Renewable Energy Lab (NREL) confirmed that homes with solar power systems sell about 20% faster and for 17% more, based on a comparison with equivalent non-solar homes across several California subdivisions.

  4.  Solar panels protect you against rising electricity costs.  When you go solar, the cost of your electricity will be fixed for the life of the system (25-35 years).  You cannot say the same thing about local utility bills.  Those increase annually due to a number of factors including taxes, constraints in developing or operating power plants, rate cases and more.  Lock in your future now with solar panels.

  5.  Solar panels can reduce your electricity bill to zero.  Saving energy can save money, as we all know.  When your power comes directly from the sun, its 100% free.  If you have enough panels to generate all of your electricity needs, you can effectively “un-plug” from the grid and say good-bye to power bills.  Talk about freedom!

  Solar Powered Electric Vehicle Stations in Switzerland

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  I am a big believer in electric vehicles (EVs) and plug in hybrid electric vehicles (PHEVs) as the transportation of the future.  While electric battery-powered cars are much greener than their fossil-fuel combustion engine counterparts, some people are concerned that coal-fired power plants still put out emissions, so electric cars may not be so clean after all.

  Enter solar powered electric vehicles!

  Solar-powered EV charging stations are popping up all over the world, including in beautiful Switzerland.

  

  Solar Powered Electric Vehicles in Switzerland

  You can find a brand new solar EV charging station in Weissenohe, Switzerland, off the B2 Autobahn.  Constructed by iKratos, a German solar company, the “Solartankstelle”, which translates as “Solar Gas Station,” will be a stop for electric vehicles to plug in and “refuel” along the road.

  According to iKtratos, the solar panels covering the EV charging canopy will generate about 3,000 kWh of electricity per year.  This amount of solar energy can power about 10,000 EV miles/16,000 kilometers in a full-sized EV such as a Nissan LEAF or Tesla Roadster.

  With solar power electric vehicle stations in Switzerland, you may soon be able to drive across Europe in an electric car.  In fact, Germany – which is the world’s leader in solar power – has about 300 solar recharging stations like this one!

  Solar Installation Checklist

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  

  Solar installation - do it right!

  Thinking of installing solar on your home?  Do you own or manage a building on which solar panels will be installed?

  Before you go forward, consider this solar installation checklist:

  1.  Research the solar installer beforehand.  Check the Better Business Bureau, and read reviews of their past projects.  Ideally, you should contact customers to ask them directly about their experience with the solar installer, including cost, quality of work and materials, timeliness and more.  Make sure you are dealing with a licensed solar professional.

  2.  Get information on the estimated solar energy production for your rooftop.  A solar installer should have tools to help you determine how rooftop solar panels will perform on your property.  Factors such as shading from landscaping or adjacent buildings could affect the efficiency of solar panels.

  3.  Research overall solar production rates in your region.  In addition to considering the potential of your individual property, find out how well the solar panels on other buildings have performed.  Solar radiation varies depending on latitude and the angle of the sun, which changes with the seasons – more dramatically the further north you go in the Northern Hemisphere.

  4.  Check permitting requirements.  Make sure that any required development permits are obtained before installing solar panels.  Depending on the age of the building, there may be structural code issues, or even historic building restrictions.  If you live in a subdivision, there may be homeowner’s association rules governing solar panels.

  Do your homework before purchasing or leasing solar panels!  With a solar installation checklist, you can be confident that switching to solar will be a sound investment.

  Solar Panels Save Homeowners Big Money in Anaheim California

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  

  Solar panel programs in Anaheim Calfornia

  Anaheim, California is known for sunshine and Disneyland, but its also one of the best places to live if you want to save on solar power.  Since 2008, Anaheim has had a generous solar incentive program that allows homeowners to save big money on the installation of solar panels.

  The municipal electric utility in Anaheim is one of the most generous of all offered in the state of California.  Can you believe that solar panels will qualify you for a $3.72 per watt rebate, which is nothing short of astounding, compared to the mere $0.25 rebate offered in Northern California by PG&E.

  If you live in Anaheim, however, you will need to act fast if you are not already part of the solar rebate program. Applications will be accepted for the 2012-2013 fiscal year beginning on January 4, 2012.  If you sign up, you can calculate your savings as follows:

  • An average American home uses about 900 kilowatt hours per month, which results in a monthly electricity bill of $130.
  • An average-sized residential solar power system of about 2.7 kilowatts (360 square feet of roof area) costs about $29,000.
  • The federal tax incentive program can reduce the cost of a residential solar panel installation by 30%, or about $8,700 in Anaheim, for a total cost of about $20,300.
  • With the addition of the Anaheim public utility rebate, the final installation cost is merely $10,200.

  As a result of the generous Anaheim rebates, a homeowner can repay a solar panel investment in a mere six years with monthly savings on electricity bills.  Compared to the average ROI (return on investment) for solar panels of 10-12 years, homeowners in Anaheim can recoup investments in about half the time!

  Solar panels save homeowners even more money in Anaheim through net metering, that credits customers for excess solar electricity generated by a solar energy system.  Among the reasons for the generous solar rebate program is the fact that California requires municipal utilities to offer rebates through the state program.  For the 2012-2013 fiscal year, Anaheim must offer solar rebates for a combined total of 330 kilowatts that are generated by residential PV systems.

  The kilowatt cap means that about 100 Anaheim households can take advantage of the solar rebate program next year.  In order to qualify, you must work with a certified solar installer to verify certain installation specifications.

  If you are interested in the program, print out the application from the City of Anaheim’s website.  After the application is submitted, you can track progress through the city’s online PowerClerk application.

  Solar Power for Electric Vehicles

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  

  Use solar power to charge EVs

  I have long been blogging about electric vehicles (EVs) and their promise to get us off of fossil fuels for commuting and more.  If you own or are considering an EV, why not tap into solar power for its fuel?

  Owners of electric vehicles stand to save $60,000 in fuel costs, not to mention significant strides in reducing global warming and improving health.  The EPA estimates that the average American drives 33 miles a day, which is about 12,ooo miles each year.  With an average mpg (miles per gallon) rating of 23, you can estimate that an American car will use over 530 gallons of gasoline each year.  Now, let’s factor in a cost of nearly $4 per gallon, and the overall cost is $2000-2500 annually, as of the date of this publication.

  Beyond the fuel for combustion engine vehicles, the maintenance involved is expensive. The Automobile Association of America estimates that maintenance costs is about $540 per year, not including catastrophic failures, which can run much more.  Overall, Americans spend about $250o each year on their vehicle.

  If you go with an electric vehicle, maintenance is even lower:  The motor is the only moving part, and it turns on a couple of unstressed life-time bearings: aside from tires and windshield wipers, it may never need maintenance. It is quieter (no engine or exhaust), smoother (no transmission), handles better (low centralized mass), is sporty (has immediate pedal response and makes its own energy when slowing), and because the brakes are only lightly used they may last forever.

  When it comes to solar power for electric vehicles, it varies.  The first mass-produced EV, the Nissan Leaf, received a government mileage rating of 2.9 miles per kilowatt-hour.

  If you switch to solar power for electric vehicles, the cost of operation can be as low as 10 cents per kilowatt/hours, depending on the area in which you live.  If your electricity cost is at the rate of 30 cents per kWh, the annual cost of recharging an EV (4000 kWh per year) will be about $1200, which is considerably less than if you used fossil fuel for your vehicle.  Using a “time of use” plan (TOU), you can save even more.  Recharge the battery of your EV during “off peak” hours of midnight to 7 a.m. and you can save more than 90% over the regular cost of gas and maintenance of a fuel combustion engine vehicle.

  So, how can you save money and energy using PV panels to recharge electric vehicles?  To start, PV (photovoltaic) solar panels are rapidly dropping in price, including government tax credits and rebates.  Considering the fact that PV solar panels generate electricity during daylight, the annual generated value of 4000KWh costs about $800.  Add in the fact that PV panels last up tp 25 years, the system will pay for itself!

  Of course, switching to soalar power for electric vehicles is another step toward weaning ourselves off fossil fuels, the burning of which is leading to global climate change.  EVs in general are catching on, with thousands of charging stations being installed and hundreds of thousands to come.  Fast chargers allow EVs to charge in less than half an hour. Moreover, EVs can be as fast as any vehicle, and motors are more efficient as they grow more powerful.

  Government Investment in Concentrating Solar Power Technology

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  

  Parabolic mirrors used for concentrating solar power technology

  The United States Department of Energy (USDOE) announced this week a commitment to invest $60 million in concentrating solar power (CSP) technology.  Used for utility scale solar power plants, CSP consists of large, parabolic reflective mirrors, which concentrate sunlight to superheat water, creating steam and turning turbines for electricity. CSP is also referred to as solar thermal energy.

  Large scale solar power plants require a lot of land and are often quite expensive.  Concentrating solar power technology – for now – is more costly than photovoltaic (PV) solar panel plants, which create energy directly from sunlight absorbed by the solar panels.

  The government investment in concentrating solar power technology is aimed at finding a way to reduce costs associated with CSP plants.  Sixty million dollars will be invested over the next three years in companies that are developing new solar technologies for CSP.  Funds will be distributed through the SunShot Initiative, DOE’s competitive program with the goal of reducing solar costs by 75%.  Among the various advancements the Department of Energy hopes to encourage are: new solar collectors, heat transfer technologies, power plant engineering approaches, and improvements in steam temperature ranges.

  Where are the Solar Panels on the White House?

   » ‎ Solar Power -- Green Energy

  After months of pressure from 350.org and other renewable energy organizations, President Obama promised to install solar panels on the White House again to set an example for the American public.  Originally, the White House had solar panels on its roof during the administration of President Jimmy Carter in the 1970s.  The solar hot water panels were removed when President Reagan took office in 1980.

  President Obama promised on October 5, 2010 to install solar hot water panels, as well as solar photovoltaic (PV) panels, on the White House.  More than a year has passed, but there’s no sign of the solar panels.  Originally, we expected to have solar panels on the White House by spring 2011.

  With the anniversary of the solar White House promise, 350.org representatives made a call to the President, asking him to honor his statement:

  “Supporters of the campaign are asking President Obama to demonstrate leadership, showcase cleantech innovation, and bring to view environmental stewardship by turning the most visible home and building in America into an environmental model for others. LEED certification would accomplish this feat.”

  Instead of solar panels on the White House, the President has advanced its “Turn the White House Green” initiative.  Among other things, the goal is to encourage United States citizens to add solar panels to their homes and increase energy efficiency.

  Of course, with a solar-powered White House setting an example, perhaps more residents would be likely to follow suit.

  What do you think about White House solar panels?  Push to install them, or abandon the effort?

  Can Solar Power be as Cheap as Coal?

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  For people wondering about the relative costs between renewable energy and grid-based (usually coal or gas) electricity, the biggest question is, can solar power be as cheap as coal?

  

  Solar power compared to coal based electricity

  Granted, installing solar panels requires an upfront investment, but the decision of whether or not to go solar often depends on how quickly you can recoup your funds through savings on your utility bill and reductions of greenhouse gas emissions.  People considering switching to solar power have many factors to think about.

  Among those considerations include the cost disparity between solar power and other grid-based sources including coal.  In addition, think about whether you will install solar panels at your property (distributed generation), or purchase (or lease) solar electricity generated by your utility.  Although solar has not yet reached grid parity with conventional power sources, it is fast reaching that goal.

  Recently, Scientific American examined data from the Department of Energy’s National Renewable Energy Laboratory (NREL) collected over 30 years, to project a timeline for when we will achieve grid parity.  They predict that this milestone will be reached within the decade, or sooner, if conventional electricity prices continue to rise.

  Switching to solar power can help even out peaks in electricity demand, as well as guard against rising utility costs over the years.  Whether you purchase or lease solar panels, you can easily reap the benefits of solar power vs. coal.

  Utility scale solar shows great promise for people looking for cheap power.  Yet, owning or controlling your own solar power system allows you more predictability and cost savings than you might achieve otherwise.  As consumers realize that public investment in solar power is a better investment than fossil fuel energy, many experts expect that millions will soon join the solar revolution.

  How Much Solar Power Can You Tap From Your Roof?

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  Ever wondered how much solar power you can tap from your roof?  Rooftop solar panels are gaining in popularity, but not all property owners realize the impact of site-specific conditions on the efficiency of solar cells.

  

  How to calculate solar incidence for property

  Scientists from the University of Gothenburg have created a tool that calculates the maximum magnitude of solar incidence, meaning the time of sunlight exposure and time spent in shadow.  People can use the tool to determine the difference between rooftop solar and ground-mounted solar panels.  From there, a cost-comparison can help them decide whether to install solar and, if so – where?

  Solar incidence is reduced by obstacles between sunlight and the panels themselves.  These include overhanging vegetation and nearby tall buildings.  In addition, rays of sunlight need to strike rooftops at an optimal angle in order to most efficiently generate power.

  The new solar calculator tool uses computer-based geographical information systems (GIS) to collect, store, and analyze geographical data.  A model showing 3-D surroundings of a rooftop shows how shadows may impact solar panels installed on a roof.  From there, you can calculate how much solar power can be generated.

  Of course, the shadow effect will change over the course of a year, throughout the seasons.  The new tool can show total solar radiation on every part of a rooftop for each month, or over an entire year, calculated in kilowatt hours (kWh) per square meter.

  The solar energy project has been carried out by the University of Gothenburg in collaboration with WSP Analys & Strategi, and it has just presented its final report. The project has been financed by the SolEl programme, the Research Foundation of Göteborg Energi, the City Planning Administration of Gothenburg and the Region Västra Götaland County Council.

  Solar Thermal Power Plant

  How does solar thermal compare to solar PV?

  If you are asking the question, then you probably need to know the major differences between the two renewable energy systems that use the power of the sun.

  Solar photovoltaic (PV) power is probably what you are most familiar with.  PV panels are the blue-shaded rectangular installations that include silicon solar cells that convert sunlight into electricity.  These are typically installed on individual properties to supply distributed generated electricity.

  On the other hand solar thermal is utility-scale solar power.  Using parabolic mirrors to concentrate sunlight to super heat water in a tower to create steam and turn generators, solar thermal is more efficient than solar PV.

  Just how more efficient?

  PV has an efficiency rate of about 12%, costing approximately 25-35 cents per kilowatt hour (kWh).  On the other hand, solar thermal boasts an impressive 55% efficiency, at a mere 12-15 cents per kWh.

  PV solar panels tend to get more attention because they are heavily subsidized by governments.  This is in part because people believe that they have the longest payback.  But others believe that the lowest-cost energy technology – solar thermal – should be promoted over photovoltaics.

  What are your thoughts?  Solar thermal or solar PV?

  Dow Powerhouse Solar Shingles to Transform Residential Solar

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  After years of anticipation, Dow Powerhouse Solar Shingles are finally available this month, and they stand to transform residential solar.  In case you have not heard about this amazing product, it combines regular roofing material with solar panels to create building integrated photovoltaics (BIPV).  Solar roofing materials allow people to both re-shingle their rooftops and also install solar panels with less bulk and aesthetic impact.

  

  Dow Powerhouse Solar Shingles

  Dow Powerhouse Solar Shingles first will be available in October 2011 in Colorado, and then rolled out thereafter to California and other states in 2012.

  Solar roof shingles are unlike regular solar panels.  They can be installed just as regular asphalt shingles, and weigh less than PV panels.  The shingles are glass-free and created with thin-film solar cells, making them like conventional roofing shingles in nearly every aspect, except their ability to generate clean, solar electricity!

  Dow Powerhouse solar shingles can be walked on, stacked and dropped.  They operate with a plug-in modular system to simplify electrical connections. Consumers have been eagerly awaiting this product for years!

  The biggest drawback at this time is the fact that Dow has not yet stated what the price of their solar shingles will be.   We do have one hint, however, from Dow Solar Vice President Jane Palmieri who has stated that solar shingle systems may cost up to 15 percent less than conventional residential solar panel arrays.  This means about $12-20,000.  Palmieri also stated that the system will recoup installation costs in “first part of its intended life,” and that the system “has a lower net cost over its lifetime than a conventional roof and grid-supplied electricity.”

  Dow Corning is targeting homeowners that need new roofs, to consider the new solar shingles.  Fortunately, solar roof shingles may qualify for solar rebates and tax credits, which help to further defray costs at the outset.

  What Would it Take to Convince You to Switch to Solar Power?

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  Sure, you’ve heard all about global climate change, and maybe you’re concerned about the rising cost of utilities.  No matter your political allegiance, your income, or other factors, we want to know – what would it take to convince you to switch to solar power?

  

  Installing solar panels (image from Lester Lefkowitz/Getty images)

  Let me be clear:  we have no dog in this fight, so to speak.  I don’t work for any solar power manufacturer.  I am not a politician, nor am I employed by one.  Just curious as to what factors are considered by property owners in deciding whether or not not to install solar panels.

  Over the past three years blogging on solar power and solar panels, we’ve determined that people are worried about three primary factors: (1) cost; (2) maintenance or hassle; and (3) efficiency.  The cost of solar panels has fallen over 50% in recent years, there are still generous government incentives, efficiency has increased, and maintenance is practically zero.

  Install solar panels and then enjoy free solar electricity for the life of the system – 25-35 years.

  With all this great information and continued support for solar energy, not to mention the security that switching to clean energy will give you in the face of rising energy costs, please tell me – what would it take to convince you to switch to solar power?

  Looking forward to your comments below!

  Solar Power Favored by American Citizens Twice as Much as Traditional Energy Sources

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  Would it surprise you to learn that solar power and other renewable resources are favored 2:1 by American citizens over traditional energy resources like coal and gas?

  

  More than half of Americans favor solar power

  Recently, two polling companies, representing each of the major political parties in the U.S., determined that twice as many U.S. citizens favor solar and clean energy than those who don’t.  A full 62% of the people surveyed support continued government investment in clean energy systems that create green jobs.  On the other hand, 31% stated that they believed it was a waste of taxpayer money to do so.

  Democrat polester Fairbank, Maslin, Maullin, Metz & Associates (FM3) conducted the poll with Republican pollster Public Opinion Strategies. The companies work independently on many issues, but together on others like solar power. In this case, they were conducting a poll on behalf of a coalition of clean energy groups in Ohio.

  The timing of of the poll was right after the announcement that solar energy company Solyndra filed for bankruptcy, after receiving a government loan.  So, an underlying question was whether Americans would respond with an unfavorable view of the solar industry overall and lack of support.  Fortunately, the results showed that people are viewing the Solyndra bankruptcy as a as just one bad company that was an isolated case.

  Perhaps not surprisingly, support for solar power is higher among Democrats (77%) than Republicans (49%).

  What would your answer be?  Are you in favor of solar power and other renewables, or not?

  Solar Thermal Compared to Solar PV Power

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  Solar thermal power is quite different than solar PV power.  The latter uses traditional solar panels, usually installed on rooftops or ground-mounted to generate solar electricity.  PV power can be generated by individual installations, or via utility-scale solar power plants.  Solar thermal, on the other hand, is a large-scale utility-scale operation.

  

  Solar thermal parabolic mirrors

  Solar thermal energy is generated when large parabolic mirrors (reflectors) concentrate sunlight on a tower where fluid therein is super-heated, creating steam, which turns turbines, creating electricity.  Large amounts of land are required for solar thermal, and the method of power generation means that systems are owned or leased by utilities, which sell the clean energy to customers.

  Like PV power, solar thermal energy is clean and efficient.  Electricity produced creates no emissions and it is nearly 100% pollutant-free.  Once solar thermal power plants are installed, little to no maintenance is required.  Compared to grid-based electricity, this is cheaper over time because fewer employees are required.  However, solar thermal is still more expensive than solar PV power.

  Compared to solar thermal, solar PV power is a superior choice because it can be sized for smaller, individual installations.  Like solar thermal power, it is renewable and non-polluting.  It is also cheaper, overall – for now!

  Solar thermal power plants are becoming more frequent, which helps customers that might otherwise not be able to afford solar power to convert to a clean, renewable power source.

  Solar Power in California

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  Solar power in California is turning out to be one of the most tapped into renewable resources.  Residential solar power is highest in San Jose and San Diego.  Bakersfield represents the third largest solar market in California.  Cloudy, foggy San Francisco rates number four in the number of solar panel installations on homes, according to information from the California Solar Initiative (CSI) and compiled by SunRun and PV Solar Report.

  

  Installing solar panels in California

  What is driving solar power in California?  Among other things, several of the largest utilities offer generous solar rebates, including PG&E, SCE, and SDG&E.  Solar financing and solar leasing options help defray out of pocket costs of residential solar power, as well.  But perhaps more than anything, homeowners are looking to save money on their utility bills.  High electricity costs drive people to consider free solar power and guard against utility rate hikes in the future.

  Solar power systems are virtually maintenance-free after installation and will generate clean, free electricity for 20-30 years.

  Seasonal Solar Lights

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  Now that its time to start thinking about decorating your home for the holidays, consider seasonal solar lights.  Instead of strands of incandescent bulbs that rely on electrical power, save money and reduce your carbon footprint with outdoor solar powered lights.

  

  Seasonal solar lights from Target

  Think that outdoor solar lights are dim and hard to see?  Think again!  LED lighting is actually brighter than traditional holiday lighting counterparts and lasts much longer.  While these seasonal solar lights glow more brightly, they also “sip” power, comparatively.  LED holiday lights can be powered with grid-based electricity or with solar power.  When you opt for outdoor solar lights, the only thing you’ll miss this year is the giant power bill at the end of the season.  Run your holiday lighting display each and every night – all night if you wish!  Forget worries about blown fuses, as well as the potential of accidental fires.  LED light bulbs burn cool to the touch, making them safer across the board.

  Its no surprise that solar Christmas lights are increasing in popularity each year.  And, they’re affordable at only about $5 per strand.

  Give a gift to the Earth, and save your hard-earned money for holiday gifts instead of the utility company this year.  Invest in seasonal solar lights and enjoy the glow of a smart, safe holiday lighting display.

  Solar Prices Continue to Fall: 17% Drop in One Year

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  

  Solar prices continue to fall

  Every year, the news keeps getting better and better for people considering home solar power.  Solar prices continue to fall – with a 17% drop in one year (2009-2010).

  Last week, a new study was published by the Lawrence Berkeley National Laboratory, commissioned by the U.S. Department of Energy, showing the overall trend to more affordable solar panels.

  This leads many people to declare, now is the time to go solar!

  Looking at solar installation costs alone, homeowners can save 43% more than just twelve years ago.  That’s practically half-price installation in the past decade!  In a single year, from 2009-2010, the industry saw a 17% drop in solar installation costs.

  The Berkeley report analyzed data from over 100,000 distributed generation (residential and commercial) solar installations, and determined that the costs of solar panels, as well as costs of installing them, along with necessary equipment such as solar inverters, have fallen off dramatically.

  Perhaps the most determinative factor in falling solar prices is decreasing costs other than those associated with solar panels themselves (lower installation costs and streamlining manufacturing), rather than to invest in more R&D.   Many believe that solar power is at – or close to – grid parity with coal-fired power plants.

  Factor in solar incentives, tax rebates and financing options (including solar leasing) and many more people can finally afford to make the switch to solar power.  Isn’t it time you considered the same thing?

  Solar Research for the Solar Energy Grid Integration System

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  

  Solar energy grid integration

  In 2007, the U.S. Department of Energy created the Solar Energy Grid Integration System, a competitive program that encouraged solar research that can better integrate solar energy generated by panels installed on rooftops or ground-mounted into the electrical grid.

  Among several goals of the program were: (1) help encourage utilities to accept solar power; and (2) development of new solar commercial products.

  The competitive solar program resulted in a number of solar technology submissions to the USDOE.  Out of more than 25 companies/organizations that applied, the Department of Energy selected 12 to advance to “Stage 1.”  These were then narrowed down to 5 finalist companies.

  Among those included in the finalists was PV Powered, a local, Bend Oregon-based solar inverter company, now known as Advanced Energy Industries Renewables.  Its research was aimed at determining how to effectively transfer solar power, which can be intermittent – depending on cloud cover – to an electrical grid that is consistently loaded by constant energy from burning natural gas or coal at power plants.

  The Solar Energy Grid Integration System finalists also included Portland General Electric, Northern Plains Power Technologies of South Dakota and Schweitzer Engineering Laboratories.

  The results of the solar research for the Solar Energy Grid Integration System, published this week, should take some of the heat off the Obama Administration regarding the failure of Solyandra – a solar panel manufacturer that filed for bankruptcy recently, after receiving a $535 million government-backed loan from the government two years ago.

  How to Prepare Your Home for Residential Solar

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  Are you considering installing solar panels?  Good for you!  Solar power has become practically mainstream in recent years as the prices have dropped and efficiency has increased.  But before you make your investment, consider how to prepare your home for residential solar.

  

  Prepare your home for residential solar panels

  With a few simple home improvement projects, you’ll be saving even more money in energy costs when you switch to solar.  In other words, your electricity bill can be cut down to practically nothing!

  Here are our 5 tips to prepare your home for residential solar:

  1.  Check and re-seal windows and doors with caulk.  Weatherizing your home will prevent heat and cool air from leaving or coming in your home.  Caulking is one of the easiest, least expensive ways to seal air leaks and save money.  If you don’t want to do it yourself, there are plenty of professionals in your area just waiting to be hired to help make your home more air-tight and energy efficient.

  2.  Make sure you have adequate insulation.  Insulation traps warm air inside during winter, and when its hot outside, you won’t lose the benefits of air conditioning, either.  Many homeowners do not have enough insulation to help moderate temperatures in their home and they end up spending much more on HVAC to feel comfortable.  An energy audit can help you determine if you have enough insulation, or whether you can save more on energy costs by adding or replacing insulation.

  3.  Consider storm windows.  This is the final step required to fully seal your home from air leaks.  Today’s windows are much more energy efficient than those from 10-20 years ago (or even older).  Go with double-pane and make sure that they are fully sealed.

  4.  Monitor your home energy usage and reduce where possible.  Smart meters and programmable thermostats are just the start.  You can now keep an eye on when you use the most electricity and which appliances are drawing the most energy with a home energy monitor.  Even after you install solar panels, this device will help you keep energy use in check so that you don’t have to draw on grid-based electricity as often (if at all).

  5.  Use passive solar techniques.  Passive solar is such a great concept and so easy to use.  I cannot believe that there is not more written about it on the Internet!  Basically, passive solar involves allowing cool air in during the morning-  over summer months – or warm air in during winter months.  This is primarily achieved through windows.  Open them when you want the temperature to adjust and/or open or close blinds to let sunshine and heat in, or to keep it out.  Planting deciduous trees outside can also help with shading during summer and letting more warmth in over winter.

  Now that you know how to prepare your home for residential solar, what’s stopping you from taking the next step?

  Solar PV Panels Achieve Energy Payback Time in One Year

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  

  REC New Solar Technology

  Renewable Energy Co. (REC) has recently developed new solar technology that allows its solar PV panels to achieve energy payback time in one year.

  So-called energy payback time is the amount of time it takes for a photovoltaic (PV) solar module to produce as much energy as was used to manufacture it.  Efficient solar cells are just part of the equation.  REC’s solar technology uses a new method of producing silicon that requires much less energy and reduces the energy payback time to just one year.

  What does this mean for solar PV panels?  Well, to start with, other solar manufacturers have only been able to produce cells with energy payback times of five years, or more.  REC, on the other hand, uses the Fluidized Bed Reactor (FBR) process that it developed to create granular silicon – a substance that uses much less energy to produce crystalline silicon.  The energy-saving manufacturing process requires only 10% of the energy required for traditional silicon processing.  This is because the FBR process does not use heating and cooling processes.

  The FBR process was awarded the 2011 Solar Industry Award by Solar Industry Magazine on September 6, 2011.

  Solar Powered Catamarans: Enjoy Solar Boating

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  We found this great post on EcoFriend regarding solar powered catamarans!  Solar powered boating has been a favorite topic here, and our readers enjoy learning more about using solar energy for recreational purposes.

  

  Catamarans at sunset

  I’ve enjoyed boating on “regular” catamarans.  The twin-hulled design is fast, and can be powered by wind/sails, or an outboard motor.  Now, solar boating includes catamarans!

  With more and more people interested in saving the environment, and the money it costs to fuel transportation and recreational pursuits like boating, it is not surprising at all that solar powered catamarans are offered as a viable alternative.

  The following 10 catamaran designs showcased on EcoFriend are green and 100% powered by solar energy.  Here’s an excerpt from the original article on EcoFriend:

  

  Solar Catamaran

  1. Solar Catamaran float 1
  The credit for developing solar-powered Catamaran named Float goes to a California resident Jeffrey Greger. This ecofriendly Float can be put on the top of a car and taken to a lake or a calm beach to feel the water waves. The Float is spacious enough to accommodate four people. It has LED tail lights and in-built speakers. The top of the Float has solar panel that traps solar energy. The catamaran is powered by Lithium-Ion battery.

  2. Enso 1 Catamaran
  The Enso Wing sailed Catamaran is the brain child of Zack Stephanchick, an industrial designer by profession. This 140 inch boat is ecofriendly and it can be used to move in style on the open waters. According to Zack, Zen Buddhism has inspired him to design Enso. The propulsion system of this catamaran is ecofriendly. Enso is pretty spacious from inside.

  3. Catamaran powered by solar energy
  International Biological station has designed and built this solar-powered catamaran named the Helios Cousteau. It is currently running in the northeast province of Zamora, Spain. The green boat is totally sustainable and is attracting a lot of tourists. This ecofriendly boat with 80 seats has now become a part of European network of Aquatic Biodiversities Observatories. It is 19 meters long and 6 meters wide. The catamaran features 20 solar panels and four wind turbines.

  4. Electro Solar
  As the name suggest, this catamaran is powered by solar energy. It is expected that this solar-powered catamaran will participate in the Solar Challenge. This ecofriendly catamaran is made up of the hulls of a Formula 18 catamaran. The designers have fitted high-efficiency photovoltaic modules in this catamaran. The modules trap sunlight and generate about 2 KW of power. The Electro Solar can touch a top speed of around 8 knots.

  5. GO2 catamaran
  Designer Chris Rose has come up with the idea of the GO2 catamaran, which will run on Thames River. This catamaran is totally green because it is completely powered by electricity. The piezoelectric dance floor on the catamaran can use the kinetic energy of the dancers to charge the onboard batteries. The power generated by these batteries can be used to rotate electric motor fitted on the two hulls. The hulls are made up of marine ply.

  6. Biocat catamaran
  Biocat catamaran derives power from either a V10 engine or two V8 engines. The best part is that both these engines can be run with either diesel or biodiesel. This catamaran is 8.8 meter long. It can reach a high speed of 110 mph.

  7. Solar proa
  Designers Carolin Dissmann, Tibor Bartholomä, Daniel Boos and Andreas Schwab have come up with a fully sustainable solar-powered catamaran named Solar Proa. This sleek and stylish catamaran can accommodate six people. Around 14.5-square-meters of the catamaran is covered with photovoltaic panels. The onboard batteries of Proa can be recharged by using a 230 V electric socket. The Proa can hit a top speed of 6.59 knots. It is completely green.

  8. Folding solar catamaran
  The FOSCAT-32 is different from other catamaran because of its unique design. The catamaran has won the prize at A’ Vehicle and Transportation Design Award. This catamaran will derive energy from sun and wind. It features DC motors for taking “u-turn” comfortably.

  9. Sun cat

  Solar Powered Washer and Dryer

  Solar Washer and Dryer

  While a solar powered clothes dryer has been around for centuries – in one form or another – a solar powered washer and dryer runs on solar electricity and can save you money.

  Miele & Solvis offers a new SmartGrid-ready washer and dryer. Not only do these appliances run on solar power, but the SmartGrid can help pinpoint the cheapest times of day to run on grid-based power when the sun is not shining!

  The solar powered washer and dryer are characterized by these main points:

  • Convenience
  • Ability to determine the least expensive electricity rates and then start washer and dyers when the cost is at its lowest
  • Solar power usage

  Heat for the solar powered dryers is generated by solar-thermal collectors, which are usually used for solar hot water.  Unlike solar electricity, the collectors involve a freeze-protected fluid, which transfers thermal heat from the sun to water.  A storage tank is connected to the dryer with 4 pipes: solar heated water is transferred to the dryer which then heats up the air in the tumbler. Cool water is then piped back to the heating system. Once heated again, it goes back to the tumbler and its heat is used to remove water from clothes. This process continues, till the time all the clothes in the tumbler are dried. The best part of the system is that is makes use of less water, since water is recycled every time it is used to dry clothes. Because the system uses solar heat to heat water, energy is saved which further reduces the carbon footprint.

  The solar powered washer and dryer uses conventional sources of electricity during cold winter months.   Yet, the system’s designers claim that the machine can cut operating costs up to 50% compared to a conventional dryer and will offer an 80% reduction compared to standard condenser dryers.

  Tags:    [edit]

  

  The cost of residential solar panels is dropping

  The cost of residential solar panels is dropping – still – which is great news for homeowners looking to go solar.  The effect of falling solar prices is that the number of solar power installations are predicted to grow by over 15% per year.  Overall, the cost of solar panels has fallen almost 20% as of August 2011.

  While homeowners enjoy lower solar panel prices, solar manufacturers are looking at flat profits and price wars with competitors.  Even a difference of a few pennies per watt will make a difference among the competition.

  Why the dramatic decrease in solar prices?  Some answers are offered in this video:

  As the cost of residential solar panels is dropping, interest in solar leasing is also gaining traction in states where people might not ordinarily consider solar power.  Instead of purchasing, homeowners can enter a contract to lease solar panels via a monthly fee that is lower than their current electricity bill.  The fee is set for the duration of the solar lease, which means no rate increases for a period of 20 or 30 years!  Alternatively, homeowners may consider a power purchase agreement (PPA) in which solar power is generated off-site and sold to customers at a cost lower than grid-based electricity.

  With solar panel prices falling, homeowners can now expect to pay between $15,000 to $30,000 for a complete rooftop solar power array, including installation.  Fortunately, the retail cost can be slashed in half (or more) with generous federal, state and local rebates and tax incentives.

  Isn’t it time you took advantage of falling solar panel prices?

  Solar Pool Heaters: Extend Your Outdoor Pool Season

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  

  Solar pool heaters are easy to install and inexpensive

  Solar pool heaters are an easy-to-install, clean and environmentally friendly way to extend your outdoor pool season.  Many people heat their outdoor pools with natural gas, propane, heating oil or electric heat pumps.  Among these options, heating your pool with solar power is the least expensive option – from initial purchase and installation, to the fact that solar pool heaters are inexpensive to maintain.  Perhaps most importantly – solar power is free!

  Unlike gas, propane or heating oil heaters, you will not need a gas contractor to hook up or service solar hot water heaters for your swimming pool.  Nor do you need an electrician.  In fact, solar pool heaters are an easy, DIY home improvement that can be installed in a day, or less.  When you order a solar kit, all you should need is some pvc pipe and glue.  Simply use a hacksaw and screwdriver to install your system, then enjoy free solar heated water!

  Solar pool heaters use a number of small black hoses that are formed together in solid EPDM rubber mats. The solar mats can be mounted in a south-facing rooftop, or laid on the ground.  Alternatively, they can be installed on plywood, angled toward the sun.  Collector tubes, comprised of pvc pipe, form the top and bottom of the solar mats.  As the water flows through the tubes, it is warmed by sunlight, then distributed back through solar collectors, to the swimming pool.  The simple system helps homeowners save on the cost of solar heat for outdoor pools. From a three-way valve, each pass of the filtered water through the solar collectors returns water that has been heated by 5-15 degrees.

  Some solar pool heater systems can be installed within a single day.  No need for professionals – this DIY solar power system can be up and running before your Saturday is over.

  Solar pool heaters can be a simple, DIY homeowner installation. All you have to do is strap the solar mats to your roof, bolt them down the headers, and run pvc pipe up the side of the house to the collectors.  From there, run the pipe back down to the pool.

  If you don’t have rooftop space, you can build plywood platforms, or install the solar panels on the ground, provided you place them at an angle to face the sun.

  Why not extend your outdoor pool season with solar pool heaters this year?

  Spray On Solar Power Technology from Mitsubishi

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  

  Spray on solar power

  Spray on solar power technology from Mitsubishi could transform everything from buildings, cars and clothing into energy-generating surfaces.  Thin solar cells – less than 1 millimeter thick, and which weigh 1/10th of similarly sized crystalline solar panels – are the latest in building integrated photovoltaics.

  The Japanese-based company has been part of a clean tech revolution starting in March 2011 after the devastating tsunami and resulting nuclear power plant meltdowns.  Government has backed research and development of solar power and other green energy sources.

  Mitsubishi Chemical Corp has developed spray-on solar power technology with solar cells that use carbon compounds that operate semiconductors when dried and solidified, which means they can generating electricity when exposed to UV light.  Thin film solar, like this spray on solar technology can save space and cut down on weight normally associated with conventional solar panels.

  Mitsubishi Chemical’s spray-on power technology promise a potential light-to-electricity conversion rate of over 10%. Traditional crystalline silicon solar panels provide an efficiency of as much as 20%, but – as noted above – less space and less weight of the spray on solar cells gives the technology an advantage.  Moreover,  Mitsubishi hopes to improve efficiency to 15%  by 2015.

  Diamond Solar Panels in Skylights: Building Integrated Photovoltaics

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  Building integrated photovoltaics is a term describing the unique design of structures to incorporate solar panels with little to no visual impact.  Diamond solar panels in skylights allow natural lighting into rooms, as well as generate clean, free solar electricity.  In commercial buildings, these solar panels will reduce electricity requirements for air conditioning, heating and lighting.

  Solar windows finally may be ready for primetime!

  

  Diamond solar skylights

  Solar skylights have been considered for some time.  With these diamond solar panels in skylights, energy savings can start racking up, as well as a significant reduction in CO2 emissions.  Not only less use of grid-based energy will result, but office buildings and malls no longer will need gas-based generators for back-up power.

  The California-based company, EnFocus has designed diamond power panels that not only reduce the intensity of sunlight coming in through skylights, which can avoid overheating, but also uses that  energy to generate electricity.  The design, for commercial buildings, is comprised of weatherproof solar panels.  Each panel includes a series of lenses that can concentrate sunlight 400x.  This concentrated energy is directed to high efficiency photovoltaic solar cells, which track the light as it passes across the sky.

  Each Diamond solar panel in skylights can generate 720 kilowatt-hours (kWH) of electricity per year.  In addition, they effectively decrease the heat load of the building by about 2.1 million BTUs annually.

  As for the cost?   The return on investment (ROI) for these diamond solar panels in skylights is a mere 5 years!

  Solar Parking Lot Using Photovoltaics

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  One of the reasons that rooftop solar panels are so popular is that they effectively use space exposed to UV light, with untapped potential.  A solar parking lot using photovoltaics is a similar concept.  Flat surface area that cannot be used for much else when vehicles are not present.

  

  Solar Parking Lot using Photovoltaics

  Using solar technology that is being researched with solar roadways, incorporating PV cells and other electronic devices into pavement is no longer a far-fetched idea.  Along these lines, Solar Roadways received generous grant money in 2009 to develop a 12′ x 12′ solar pavement prototype.

  The solar pavement prototype was so impressive that additional grant money has been awarded to Solar Roadways to develop a solar parking lot using photovoltaics.  Not only can this technology generate clean, free solar electricity, but solar pavement will also be able to melt snow and ice from its own energy to keep parking lots clear and safe.  Solar power generated by a layer of embedded LEDs can illuminate traffic signals, and excess energy generated can even be used for charging electric vehicles parked at the lot.

  All surface areas covered by asphalt or pavement could eventually be “solarized.”  Beyond roadways and parking lots, why not bike paths, recreational blacktop surfaces, and even driveways?

  The potential is exciting, but likely years away.  A single 12′ x 12′ solar pavement square costs about $100,000.  Yet, covering these surfaces with solar cells could generate three times more than the amount of electricity we currently consume as a nation.  With continued solar technology advancements, increased efficiencies and decreased materials costs, it might not be too long before we’re driving, parking and playing on sunshine!

  Home Solar Power in New Jersey

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  Home solar power is really taking off in New Jersey!  In case you didn’t know, the state is one of the top solar power generators in the U.S.  That’s right – New Jersey.

  

  Home solar power in New Jersey

  Commercial and residential properties alike are taking advantage of low costs of solar panels and generous government rebates that minimize the initial investment.  Home solar panels are often on the wish list of property owners, but they are concerned about the price.  For some people, leasing solar panels can be the answer.  Among a number of companies that offer this option in New Jersey is SunRun (we’ve blogged about SunRun and its solar panel leases in the past here!)  For little to no money down, solar panels can be installed on your rooftop, remaining in the ownership of the solar company.  You then pay a small amount for the lease each month, which is usually substantially lower than grid-based electricity.

  In New Jersey, home solar power is usually generated by rooftop panels.  Because it is a relatively small state, New Jersey lacks large open spaces for utility-scale solar production.  Instead, distributed generation solar power can be found all over the state, from street lights to rooftops.

  New Jersey’s approach to solar power is working.  With fewer utility-scale solar projects and more site-by-site distributed generation installations, environmental concerns associated with siting solar farms are practically nonexistent.

  Home solar power is increasingly seen all over the Garden State.  Just drive through a neighborhood and see how many rooftop solar panels you’ll find!

  Five Reasons to Consider Residential Solar

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  Many Americans are interested in solar power, but of these people, most have questions that hold them back from switching to the renewable resource.  With information to show that a solar power system is worth the investment like these five reasons to consider residential solar, perhaps more people will make the switch!

  

  Benefits of residential solar

  1.  Saving Money

  That’s right.  Notwithstanding initial investment costs for residential solar, you can save a lot of money through solar rebates and incentives that can slash the price of solar installations.  Many people find the return on investment to be only six to eight years, after which you can enjoy 100% free solar energy for the life of the system, which is usually 25-30 years.

  If you don’t want to purchase, you can lease solar panels for no money down.  With solar panels, residential properties experience at least 30% lower utility bills, in addition to the ability to take advantage of net metering (selling back excess energy into the grid for a credit).

  2.  Insurance Against Rising Energy Costs

  Beyond the initial costs of installing residential solar panels, you should think about the fact that you will save significant money each and every month on utility bills, and also prevent the impact of future rising energy costs.  Some experts believe that conventional energy sources will cost as much as 50% more by 2035, according to United States Energy Information Administration (EIA).  With a solar power system, your costs are stable and predictable, giving you insurance against skyrocketing bills, as well as protection against blackouts caused by man-made and natural disasters.

  3.  Flexibility

  One of the best things about a residential solar system is that you can start small and add to it later.  In addition, you may start with a solar hot water heating system and then add solar PV panels for electricity later.  Even better, you can continue to add solar panels to the system as necessary.

  4. Inspring Others

  When you go solar, the impact is not just limited to your own checkbook and carbon footprint.  The mere sight of solar panels on a neighbor’s rooftop can inspire others to consider residential solar.  In fact, your installation just may empower the entire neighborhood.

  5.  Environmental Responsibility

  The step of installing solar panels on your rooftop will probably continue to inspire other people in the community to go green, as noted above.  But beyond that, you can rest assured that residential solar will make a difference in the world, both with respect to cutting down use of fossil fuels and preserving natural resources, and to reduce personal energy consumption overall.

  Solar Power Growth

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  In the past 5 years, solar power growth has been exponential.  In the midst of a recession, no less.  As people look for ways to save money and live in a more environmentally sensitive manner, renewable energy options like solar panels are being considered more often.

  

  Solar power growth is sweeping across the nation

  Just a decade ago, solar panels on rooftops of homes were a rare sight.  These days, you can probably see solar power growth throughout your town, if not in your very own neighborhood.  You might even be considering installing solar panels yourself.  And why not?  With generous governmental rebates and incentives, you can save up to 80% on the upfront cost of solar panels and then immediately slash monthly power bills.  Your home value will increase, as well, by $20 for every $1 saved in electricity bills annually.

  One of the biggest factors fueling solar power growth is the increase in fossil fuel prices for gasoline and oil.  Many experts agree that we are approaching grid parity, at which it is not any more expensive to go solar than to use traditional electricity power sources.

  With solar technology improving each and every day, some experts say that getting on board with solar power is critical now, or you will risk being left behind.  Today’s solar panels will still generate ample solar electricity, even if efficiency improves in the near future.  Even better, the power is cleaner and cheaper than the alternative!

  How Long do Solar Garden Lights Last?

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  

  How long do solar garden lights last?

  Even though solar lights for residential properties are inexpensive, many people still wonder: how long do solar garden lights last?

  There are several benefits of using home solar lights including: (1) ease of installation; (2) reliability; and (3) lower power bills.  These lights do not require wiring or trenching and are extremely easy to position or move about as needed in your yard, along your patio, driveway or walkway.

  Once you install them, they are basically  maintenance free.  You can enjoy free solar electricity every night the sun goes down, without worrying about turning outdoor lights on or off.

  Yet, if you are making an investment in solar garden lighting, you’ll want to know whether the product will still work 1-2 years from now.  Or, even whether the lights will last through the night on a regular basis?

  With all the products on the market these days, how can you know?

  We’ve done some research on long-lasting solar garden lights.  When it comes to outdoor solar lighting, there are many options for homeowners and small businesses, in a variety of styles and price ranges.  From the outset, however, note that most garden solar lighting will stay illuminated for about 8-10 hours overnight.

  Outdoor solar lights are widely available these days in national hardware and home improvement stores.  Regardless of appearance or price, they all work in the same basic manner.

  Here is a list of types of solar lighting:

  1. Traditional solar accent lighting: You get what you pay for.  A higher price, means you’ll be purchasing solar lights that last longer with brighter illumination.  Best quality solar lights have wide solar panels, with a minimum two LED bulbs, and a cover on the bottom of the light so the light can reflect and be intensified.

  2.   LED-free solar lighting:  If you are looking for solar garden lights that do not use LED bulbs, you can go with LED-free solar lighting such as Lowe’s Regent Lighting Solar Motion Floodlight, which has a large solar panel for charging with a 15-watt halogen bulb. Because it’s a motion detector, it automatically turns off during the day and turns on when it senses motion.

  3.   Bright lights: Go with solar floodlights for bright accent lighting that can be focused on a specific area.

  Overall, determining how long solar garden lights will depend on several factors including your location, the season and weather.  During spring and summer, the solar lights will come on regularly and stay lit overnight.  If you buy high quality solar lighting, you can be assured that your investment will last years and give you seasons of solar electric lighting.

  Your best bet is to compare brands and prices through online reviews.  No one can tell you better than other homeowners how long solar garden lights last in your neck of the wood!

  The Truth About Solar Panels

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  

  The truth about solar panels

  We’ve posted several articles discussing the advantages and the disadvantages of solar power.  People are more and more interested in learning about this renewable resource, but there are several solar myths that may keep people from taking the next step toward installation of solar panels.

  Its time to separate out the truth about solar panels from the persistent legendary myths.  Things have changed, and now its time to change your mind too!

  1. Solar Energy is Affordable.

  One of the biggest hurdles that prevent people from going solar is the fear about the cost of solar panels and the return on investment.  However, now is a great time to consider solar panels.  Prices have dropped by more than half in recent years, and generous local, state and federal rebates further defray the cost.  Then, you can start saving immediately on your power bills from the very first day!

  2. Solar panels work even when its cloudy and cool.

  You don’t have to live in California or Florida to effectively rely on solar power.  All that is needed is UV light.  When the sun comes up, even if it is filtered by heavy clouds, solar panels still can generate electricity.  Granted, they are most efficient in direct sunlight, but don’t think solar is not an option if you aren’t located in a sunshine state.  In fact, Germany is considered to be the solar capital of the world – not really the sunniest location on earth!  When it comes to temperature, solar panels work best when its not too hot.

  3.   Consumers should not wait for solar panel prices to come down.

  While technology advancements will improve efficiency and reduce the cost of materials, the biggest factor in price right now is government incentives.  Those will not last forever!  If you miss out on rebates that save you 50%, does it matter if solar panel prices drop 20% in the next few years?  Buy now!

  4.  The return on investment for solar panels is immediate.

  The biggest misconception regarding solar is that you have to stay in your home many years to recoup the investment.  But many people fail to realize that not only do you save significant money on your annual utility bills, but for every $1 you save, the value of your home increases by $20.  Slash your annual electricity bill by $1000 and that is an instantaneous $20,000 in equity.  Moreover, houses with solar panels sell faster for more money.

  5.  Solar panels are easy to maintain.

  In most cases, solar panels are an “install it and forget it” system.  Many manufacturers include maintenance as part of the price of a solar panels system.  As a property owner, you just need to make sure that any shading from landscaping does not occur.  Keep the solar panels cleared of snow, dust or debris.  And while you are at it, enjoy your free solar electricity!

  Selecting Solar Panel Ground Mounts

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  

  Ground mounted solar panels

  When you are looking to construct a solar array on the ground, instead of rooftop solar panels, you will need to select solar panel ground mounts.  Among the options are fixed-, single-, or dual-axis trackers.  There are costs and benefits associated with each, which will vary depending on factors such as the latitude of your location, climate, landscape and the size of the ground-mounted solar array you are proposing.

  If you have a limited budget and/or are installing a relatively small solar array, a fixed-axis solar ground mount may be your best bet.  They are the least expensive option and are easy to maintain because they do not have mechanical, moving parts.  Fixed-axis systems can be used both on the ground and for rooftop solar panels.

  Solar tracking ground mounts can help achieve greater efficiency, but are more expensive.  These mounts track the movement of the sun across the sky so that the solar panel continuously receives direct sunlight.  You can choose between thermal and electrical solar trackers.  The differences between the two are seen in cost, maintenance and effectiveness.  Thermal trackers use radiant heat to activate rotation.  They are less expensive and do not require much maintenance, but they can be slow to react to solar movement, particularly during winter months.  Electric solar trackers are more precise, more expensive and require regular maintenance, compared to thermal trackers and fixed-mount systems.  But it may be worth it – they can increase electrical output 20-40% over stationary solar ground mounts.

  

  Installing solar panels on a ground mount

  Not only can you choose between thermal and electric solar trackers, solar panel ground mounts also come in single-axis and dual-axis trackers.  According to this post at Clean Techies:

  Single-axis trackers move only on one axis, usually aligned along a true North meridian. These trackers are more reliable because they are less mechanically complicated. Because of this they are also easier to maintain and consume less energy than dual-axis trackers. In addition, these trackers create less shadowing, allowing a closer positioning of panels. Single-axis trackers are more cost-effective for large installations of solar panels.

  Dual-axis trackers track the sun along two axes, allowing for a more constant and accurate angle of incidence and a higher yield. These trackers are especially efficient in cloudier climates, at northern latitudes, and in sloped locations. Because these trackers are structurally complex, they tend to have higher installation and maintenance costs. They are also larger and create a lot of shade, requiring greater space between units. These trackers have great collection efficiency, but are very expensive and are most cost-effective for smaller installations.

  Selecting solar panel ground mounts is an important part of designing the solar array that best fits your needs and budget!

  Now is the Time to Go Solar

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  Guest Post by Ben Saffer, Evo Energy

  

  Now is the time to go solar!

  Government guarantee schemes and increasing electricity bills, combined with dwindling fossil fuel resources and the dire need for solutions to climate change make solar panels for the eco and budget conscious homeowner.

  So what is solar power anyway?

  Solar power uses photovoltaic (PV) cells on the roof of your house to convert light from the sun into electrical energy which can be used in your house, or fed back into the national grid. A chemical reaction creates a flow of electrons in the solar panel (direct current or D/C), which feeds into an inverter to convert this into alternating current (A/C) to power your house.

  What if I don’t live in a sunny climate?

  Solar panels don’t actually need sunshine to work, the photovoltaic cells react to daylight. So even on a completely overcast day solar panels can generate 40% of their potential electricity yield. And you are still connected to the electricity grid, so outside of daylight hours you can draw from the grid just as before. Plus, any extra electricity from your panels which you don’t use will be fed back to the grid and you’ll actually get paid for it! (See below)

  The environmental case for solar

  The environmental case for renewable energy is becoming louder and more critical all the time. Barely a week goes by without a major news story involving the rising price of oil and gas, the terrible environmental impact of fossil fuel recovery methods such as “fracking” and tar sands which leave areas of land devastatingly polluted and emit up to 45% more greenhouse gas than even traditional oil and gas (and of course 100% more than solar). With peak oil production rapidly approaching, solar is widely seen as an integral part of the low-carbon future, and thankfully one which you can start to benefit from now.

  The financial case for solar

  Arguably just as important as the environmental benefits, there are now real cost savings to be made by going solar. Government schemes both in the UK and US now provide homeowners with compelling cost incentives for installing solar panels at home. Last year in the UK the government introduced the Feed-in Tariff (FIT) as an incentive scheme to encourage homeowners to invest in solar PV. The FIT ensures payment of 43.3 pence for each unit of electricity that their domestic solar system produces, irrespective of whether they use that electricity in their home or not. Additionally, the FIT also pays 3 pence per unit for electricity not used in the home and exported to the National Grid. The scheme is guaranteed for 25 years, and the amount will increase with inflation linked to the Retail Price Index.

  With this in place, homeowners can make around £12,000 profit over the lifecycle of their solar panels. This is on top of savings on electricity bills of between £70 and £130 every year.

  So what’s stopping you?

  Installation and all the technical know-how are handled by the solar panel provider, along with maintenance over the life of the panels. In the vast majority of cases you won’t require any planning permission to install solar panels.

  Although the initial cost of the panels is between £8,000 and £14,000, the feed-in-tariff, and bill savings ensure you will start earning this back from day one. Also, many solar panel providers offer free panels in exchange for rights to the feed-in-tariff until the cost is paid off. So there really should be nothing stopping you from going solar at home.

  Paper Solar Cells Show Great Promise

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  Breakthrough solar technology from engineers at Massachusetts Institute of Technology (MIT) shows great promise for the future of renewable energy from the sun.  Paper solar cells will not only be significantly less expensive than their silicon-based photovoltaic (PV) cells, but they will have a much wider potential for application.

  

  Paper solar cells from MIT (photo credit: MIT)

  Currently, the paper solar cells can generate enough power to run an LCD clock and are flexible enough to be folded and stuck in a pocket!  Solar paper cells will best be used to power electronic devices like cell phones, iPads and cameras.  But some expect paper solar to be incorporated into clothing and outdoor products like tents, boating equipment and sun shields.

  Unlike crystalline PV panels, the paper solar cells do not require silicon or heavy glass as a substrate.  Manufacturing solar paper will be more environmentally friendly too, as it will not need damaging high temperatures and corrosive liquids.  Impressively, paper substrate is 1000 times cheaper than glass (accounting for 40% of the cost of traditional solar panels).

  Don’t look for paper solar cells on the market just yet.  Researchers are working to improve their efficiency from 2-8%.  When that happens – most likely within the next 2 years – solar technology will include another flexible thin solar cell option.

  Solar Powered Toilets to be Installed in Dubai

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  The opulent City of Dubai within the United Arab Emirates is one of the richest governments in the world, having been built – literally – on oil profits.  So it might be surprising to learn that Dubai is a leader with respect to renewable resources and sustainable projects.  Its latest plan is to tap into solar energy for certain public services.

  

  Solar powered toilets to be installed in Dubai

  Recently, it was announced that the general maintenance department of Dubai will be installing solar powered toilets throughout the city.  The solar toilets have two primary purposes: (1) raise environmental awareness, and (2) save taxpayer money.

  Solar powered toilets in Dubai will first require the installation of rooftop solar panels on certain designated properties in the city.  Power generated by the PV panels will be used to illuminate lights, run exhaust fans and operate small water pumps for the toilet facilities.  The money saved as a result of going “off-grid” for these operations will allow a return of investment in only 2 years.

  More than just taxpayer savings is worth celebrating.  Many believe that solar powered toilets in Dubai will influence and encourage installation of other energy-saving measures throughout the city and other emirate municipalities.  Guess they will just start from the “bottom” up, and increase reliance on solar energy to save money and the planet!

  Should You Lease Solar Panels?

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  

  Leasing Solar Panels

  For people that want to switch to solar power, the cost is probably one of the biggest hurdles to cross.  Purchasing a solar panel array is expensive, and then you also have to worry about maintenance.  However, if you have wondered if you should lease solar panels, that might be your answer.

  Leasing solar panels is one of several ways that can help homeowners and small business owners finance solar power. When you enter into a solar power lease, you don’t own the system, but the terms of the lease agreement could save you significant funds that can help you with your monthly budget.

  Consider this list before deciding whether you should lease solar panels

  • What are your monthly electricity bills?
  • What would the monthly payments be (under a lease or a loan)?
  • Make sure that the payments are less than your average electricity bills
  • Do you have equity in your home?
  • Are you planning on staying in your home for at least the next 12-24 months?
  • Would you prefer maintenance or repair of the solar panels to be done by professionals, or yourself?
  • How much liquidity do you have (available cash?)
  • What is your credit score? (should be at least 640)

  Before you enter into a solar lease, check with the Better Business Bureau to make sure that the company with which you are dealing is reputable. Review the official website and make a call to your local Chamber of Commerce to gather information.

  Remember that, when you enter a solar panel lease, it is a binding contract. Both sides to the agreement must fulfill their promises, or risk facing the other side in court. Be sure to review every provision in the agreement carefully. Given the value of solar panels, you may want to consider retaining a lawyer to help you make sure that all potential concerns are addressed and there are no overly restrictive terms.

  Consider these terms for a solar panel lease:

  1. Lease term: How long will you be leasing the panels (usually at least 5 years)
  2. Lease payments: How much will you pay, how often? Is there an escalation clause that gives the solar company the right to raise the rent?
  3. Early termination: Do you have the right to terminate the lease before the end of the term without penalty? If there is a penalty, how much?
  4. Lease renewal: Can you renew the lease? How? Under what terms?
  5. Maintenance of the solar panels: This should be the solar company’s responsibility. Contact information should be spelled out specifically. Ideally, there should be a time stated within which a response must be made in case of damage or failure.
  6. Insurance: This should be the solar company’s responsibility – to insure the solar panels.
  7. End of lease: What happens when the term is over? Removal of the panels, or will you as a consumer have the right to purchase the panels at a reduced cost? How will that cost be determined?

  Solar powered outdoor shower

  Looking for a comfortable way to rinse off outside after a swim, a run, or a dip in the pool?

  Have you considered a solar powered outdoor shower?  You can save electricity for a pump and, if you go with one of the models shown above, there is no installation required.  No piping, no contractors, just a nice warm shower to enjoy outdoors.

  You can install a DIY solar powered outdoor shower with the steps below:

  1.  Find an appropriate location

  Most people that shower desire some privacy.  Look for a place that is away from windows, and, ideally, concealed with landscaping.  You will need the outdoor shower to be within a reasonable distance of the hose pipe.

  2.  Set the hose pipe

  You will need to connect the shower to a hose, which will supply the water.  One end will be tied to the valve/tap and the other will end at the shower area.  Use a shut-off coupler on the end of the hose pipe, and make sure it is reachable.

  3.  Pressure Welded Studs

  If you would like to have a base for the shower (as opposed to a free standing solar powered outdoor shower as shown above), use two pressure-welded studs on a square frame.  This will add weight and stability to the base.  Then, install wood slats within the frame, with some space between each piece to let the water drain through.

  4.  Pressure Treated Studs

  For this semi-enclosed outdoor shower, attach 4 pressure treated studs, about 6-7 foot long and screw them to the corners of the shower base (which you completed above).  Afterward, tie them together at the top with pressure treated pipes. Some people like to put a top and/or sides on their outdoor shower, but I think they are nice without one.  If you desire, you may install a glass roof or side walls with screws.

  5.  Use a Utility Hook

  For this completely DIY solar powered outdoor shower, you will now need to install a utility hook on the top of the shower roof in the center and then attach a sprinkler head in the center of the shower base joining the utility hook.

  6.  Before Showering

  To use solar heated water, you will want to fill up a water can and allow it to warm in the sunlight before showering.  Make sure the shut off valve at the opposite end is closed.  When you are ready for a nice solar powered shower, just turn on the faucet and enjoy!

  Solar panel questions answered

  Solar Panels Frequently Asked Questions

  In an article published at HubPages, I reviewed questions and answers that many people have about solar power generally, and solar panels in particular.

  Q: Is it expensive to install solar panels?

  A: Not necessarily! Depending on where you live and your energy needs, you could install a home-based solar panel system for as little as $7,500. Many states offer incentives to off-set the cost of solar panels, as well. Don’t forget energy tax credits!

  Q: How long will it take to recoup my investment in solar panels?

  A: The answer to that question depends on a number of factors, including the size of the solar panel system (number of panels), your overall energy use, tax rebates and other incentives. Estimates range between 10-15 years. As solar technology leads to more efficient solar cells, and grid-payback systems are implemented by energy companies, expect the ROI to drop to 5-10 years.  Thinking beyond just monetary investment, your contribution to help slow global warming and reduce your carbon footprint will lead to an immediate payback.

  Q: Does the process of manufacturing solar panels result in pollution?

  A: Yes, there is some environmental impact from producing solar panels, as there is with any other manufactured good. But, the environmental costs of manufacturing are outweighed by the environmental benefits of reduced fossil fuel consumption. Even the smallest solar panel system can cut household greenhouse gas emissions by as much as 50 trees!  And remember that 100% of the electricity produced by solar panels is emissions-free!

  Q: Solar power has always been a clean renewable resource – why has it taken so long for people to get interested in solar panels?

  A: Since the earliest civilizations, people have been using solar power to warm their shelters and cook their food.  But modern solar panels have only been around for about 50 years.  Solar research and development is leading to more and more efficient solar cells, with higher conversion rates.  Prices are dropping, as well, as materials become more abundant and processes more streamlined.  Still, less than 3% of our nation’s electricity is generated by solar power.  Experts expect that to change over time, with solar energy generation growing at a rate of 20-30% annually. With added tax incentives, concerns about global warming and a strong desire to become energy independent, more and more people are willing to invest in solar panels.

  Q: What about excess energy generated by solar panels?

  A: If your solar panels create more power than you can use immediately, excess energy can be used to charge batteries on which you can draw later (if you are “off-grid”).  With grid-tied systems, the extra power is fed into the grid. Some utilities credit customers based on the amount of energy put into the grid. This helps defray costs of power drawn on overnight or during less efficient solar energy periods.

  What questions do you have about solar panels or solar power in general?

  Save Money with Solar Power and Smart Meters

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  Many homes and businesses in California will be having smart meters installed pursuant to a mandate of the California Public Utilities Commission (CPUC).  But what does this mean, exactly?  How can smart meters help you save money?

  

  How can smart meters help you save money?

  In short, smart meters give consumers the tools they need to help them manage their electricity demands and lower utility bills.  When you have solar panels on your property and are grid-connected, they can also account for excess solar electricity generated, which can end up giving you a credit on your bill.

  In short, a smart meter collects information for the smart grid.  They have been described as connecting your home to the grid in a similar manner as a cable or DSL modem connects your computer to the Internet.

  Why smart meters?

  Unlike the electro-mechancial analog meters with which you are probably familiar, smart meters include digital displays that precisely record the amount of energy you use, and then sends the information directly to the utility company.  That’s right…. the traditional “meter reader” is replaced with direct, 2-way communication between your property and the utility.  This is more efficient and more accurate.

  Utilities can cut costs related to on-site meter reading and can even address service disruptions remotely.  The other benefit is that peak load times can be better managed.  Utilities can match real-time demands on the grid with information flowing directly to it.  Moreover, instead of simply looking at a consumer’s total consumption, smart meters pinpoint the exact times of day that electricity is used.  If you want power during peak hours, you will pay more than if you shift energy consumption to off-peak hours, say by washing dishes or doing laundry later at night.

  Solar Power and Smart Meters

  Generally speaking, smart meters record the solar power generated by your residential solar power system.  This allows you the opportunity for net metering to get credit for solar electricity you feed back into the grid.

  Consumers are finding that they can save money with solar power and smart meters.  First, installing solar is more affordable than ever with falling prices and continued government rebates and incentives.  Second, its much easier to finance solar power, which can further cut down on the cost of solar electricity.  Experts believe that TOU (time of use) pricing via smart meters for residential use is just a few years away.  When you factor in solar power, the impact of such a structure will be minimized because homeowners can “smooth out the gaps” in generation vs. demand.  Lots of solar electricity generation during the day (when people are at school and work), and then higher demand in the evening and morning hours.

  Turns out to be a win-win for both the homeowners and the utilities with solar power and smart meters!

  Solar powered water fountain

  Today’s post inspiration came from working in the yard this weekend.  My husband has wanted to put in a small water feature for some time.   So, he found what he thought was a great deal – a stone water fountain for less than $300.   Turns out that it didn’t include the water pump and we’d have to trench wires to the fountain for its operation.

  So, why not a solar powered water fountain?

  Turns out that my idea has already been considered (of course) and a number of sites sell these items for a solar backyard or garden.  Like solar garden lights, Among the benefits of using solar power in your garden is that you will not have to trench and wire electricity to a solar water fountain.

  

  Use solar power to operate pumps for garden fountains

  Solar powered water fountains start as low as $40.  Small solar panels are usually employed to harness free solar electricity to run the pumps necessary for a garden water fountain.

  Wondering where to buy a solar powered water fountain?  You can find them at major home improvement retailers and online.  Here are just a few sites:

  • Amazon.com
  • Solar Water Fountains
  • Garden Winds
  • Harbor Freight Tools

  I am relieved to find that I don’t have to worry about trenching or wiring to install a water feature in my backyard.  With solar power, I can have a convenient, easy to install and operate water fountain or bird bath.

  What do you think about a solar powered water fountain.  Do you have one, or does it sound like a possible answer to your landscaping issues?

  Solar Air Conditioning for Phoenix Arizona Urban Light Rail

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  One of my favorite solar power application is to use energy from the sun for solar air conditioning.  The same heavenly body that heats up the planet can also keep us cool and comfortable.

  

  Light rail stations in Phoenix Arizona are cooled with solar power

  In Phoenix, Arizona in the desert southwest of the United States, the A/C in their urban light rail stations is powered by sunlight.  This is welcome news for the people that live in this region.  During summer months, daytime temperatures can climb past 115 degrees F.  At the urban light rail stations in Phoenix, solar powered coolers can be activated with the touch of a button.  The chilled air produced can lower temps by 40 degrees.

  The solar air conditioning system will automatically shut off after 15 minutes of operation to conserve energy.  Solar A/C is available at the urban light rail stations from May through September – Arizona’s hottest months.

  Arizona’s light rail cooling system was initiated by Mayor Phil Gordon, who brought the idea back after a visit to Dubai. Phoenix has partnered with local utility NRG Energy, which agreed to fund the $300,000 project. NRG will operate and maintain the system.

  Tags:    [edit]

  

  Solar power air conditioning

  With summer here in full swing and people looking for ways to cool down in an efficient, cost-effective way, its time to consider solar power air conditioning.

  There are two new A/C units that run on solar power, and help save energy and money.

  The first is the SplitCool DC18 solar air conditioner from Solar Panels Plus.  Perhaps the best aspect about this device is not that its solar powered, but that it uses direct current (DC).

  Generally speaking, solar energy must be converted from direct current (DC) to alternating current (AC) which is what you get when you plug into a socket.  The SplitCool DC18 is a 48 volt DC air conditioning unit with a variable speed compressor.

  Use of DC means that no inverter is needed to operate the unit.  Not only does this save on the overall cost, but users also don’t experience the 15-20% power loss typically encountered during inversion. This makes this air conditioner far more efficient that a high-SEER AC unit connected to solar panels through an inverter.

  Next, there is another solar power air conditioning unit from HotSpot Energy.  This alternating current (AC) product is the ACWH18 Air Conditioner Water Heater.  The HotSpot is a 18,000 BTU ductless mini-split heat pump that runs on 220v AC power.  It is a SEER 18 EnergyStar certified unit with an integrated heat recovery circuit allowing it to make hot water as a byproduct of running the AC.  A heat recovery circuit recovers heat that would normally discarded, and uses it to make hot water at temps up to 140F.  About 100 gallons of solar hot water can be produced each day.

  The typical user with a 7-month cooling season will save $1,000 per year in electrical and water heating savings, compared to a customer running a SEER 13 unit and using a standard water heater. Even more exciting is the fact that a purchase of the solar power air conditioning unit will qualify for a federal tax credit.

  Prevent Solar Panel Theft With Bryce Fasteners

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  One of the biggest issues facing people that own residential solar panels isn’t how to pay off the investment.  Its how to prevent solar panel theft.  Right here in my own neighborhood, a set of PV solar panels were stolen from the rooftop while the owners were on vacation!

  

  Stealing solar panels can be stopped!

  Unfortunately, with the growing cost of electricity and natural gas and the expense of alternative energy sources, stealing solar panels has become more common.  This has occurred as people are more aware of the value of solar panels and are looking for cheap (free?) ways to generate electricity.  Oftentimes the criminals simply re-sell the stolen solar panels on eBay or Craigslist.

  

  Prevent Solar Panel Theft

  Yet, there are ways to stop solar panel theft that do not entail an expensive home security monitoring system or elaborate fencing.

  Bryce Fasteners is a new company that uses a unique key-entry lock to fasten residential solar panels to the roof.  These tamper-proof fasteners are customized, meaning that regular tools cannot uninstall the screws, nuts and bolts.  You’ll have to special order the drivers from the manufacturer in order to put the panels on or off.

  In short, it will be hard to steal solar panels quickly and without a lot of effort if Bryce Fasteners are used to secure the installations to the roof.

  Homeowners and professional solar installers should consider the Bryce Fasteners to prevent solar panel stealing.  If it is too tough to accomplish, these criminals would perhaps abandon the effort!

  Empowerhouse at the 2011 Solar Decathlon

  Curious about green living and solar homes?  Then you should check out sustainable and solar Empowerhouse.

  Partnering with Habitat for Humanity, local communities can soon help construct affordable, energy-efficient housing.

  To start – and to build awareness – you can see two Empowerhouses on display this year.  The first one will be part of the 2011 Solar Decathlon in Washington, D.C.  Not too far away, in the Deanwood neighborhood in D.C., another Empowerhouse will be constructed.

  After the end of the Solar Decathlon, the two Empowerhouses will be joined together in Deanwood.  Each of the structures are sustainable independent of each other, but the most optimum energy efficiency can be achieved when they join together.   Just recently, we posted about net-zero housing, so this new project is quite timely!  According to a related post:

  The major ‘green’ aspect of the Empowerhouse is the fact that it requires up to 80 percent lesser energy for cooling or heating up a room when compared with a regular home. However, even if you compare it with a very high energy-efficient home, the Empowerhouse saves on 40% energy – all this is possible as it conforms to the Passive House standard (which is the highest international standard in energy efficienty). The Empowerhouses have very energy efficient electrical appliances, energy recovery ventilation, well-located windows for utilizing natural light, heat-pump technology and more, which leads to a drastically reduced electricity bill.

  Although the sustainable, solar homes are a bit more expensive to construct, the difference is quickly made up through reduced energy bills and improvement in property value.  In addition, the Empowerhouse is designed with a modern, urban flair, using pre-fabricated building materials.

  Can you imagine living in an affordable home that pays for itself within a matter of years?  That’s what the Empowerhouse is all about!

  Solar panels for boats

  Love the outdoors?  Want to keep the air clean and clear?

  Instead of using a fuel combustion engine and/or grid-based electricity, how about solar panels for boats?  That’s right!  You can use solar power while you are out on the water, or even dock-side to charge the battery and power boat lifts.

  Solar panels for boats are categorized in two main groups:  those that help move the boat, and those that help power electrical needs while you’re on the water.  Some PV panels accomplish both purposes.

  

  Sailboats using solar power

  All types of boats can use solar power.  Sailboats, yachts, motor boats and more.

  In order to generate solar power, you don’t need bright sunlight.  Any UV light (filtered through clouds) will work.  Chances are that your boating excursion will include enough solar exposure to charge the battery and keep electrical appliances running.

  Even if you don’t expect to run a boat motor on solar power, you can at least rely on solar panels to power on-board devices.  Your GPS, cell phone, mP3 player and more can all be recharged with portable solar power from any solar panels on your boat.

  Do you use solar panels for your boat?  If so, why?  If not, why not?

  Solar Power Supported by American Mayors

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  

  U.S. Conference of Mayors shows strong support for solar power

  At a recent municipal conference last week, a survey revealed that solar power is supported by American mayors, overwhelmingly.   The U.S. Conference of Mayors included leaders from all cities of more than 30,000 people, and took place in Baltimore, Maryland.

  Among the issues facing municipal leadership are the development of clean energy technology, deployment of solar power and the creation of green jobs.  To get to the heart of the matter, a Siemens survey was revealed to illustrate the fact that renewable energy resources for clean power is a high priority for American mayors across the country.  This moves solar power, and other technologies, to the forefront.

  According to Deborah Dehaney-Howard, spokeswoman for the U.S. Conference of Mayors, the survey did not focus exclusively on solar power.  However, the results did show that many city leaders believe solar electricity production, along with energy-efficient building technologies and LED lighting systems, is among the top three most promising clean energy technologies.  However, even though the mayors admitted that the Recession has impacted city budgets, they still plan on increasing use of green energy over the next 5 years.

  Overall, one quarter of the cities represented at the conference have already established renewable energy production standards.  In fact, notwithstanding the absence of a national policy on green energy, many cities have incorporated policies to encourage clean energy like solar power within their master plans.

  

  Cities encouraging solar power growth

  Even with solar power supported by American Mayors, there are still some geographical differences across the country.  Generally speaking, you’ll find more solar electricity being developed in the West and Northeast.  Yet, overall, 46% of the cities surveyed responded in the survey that they see solar power as one of the most promising clean energy technologies.

  Solar Panels on the White House: Or Not?

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  Recently, we learned that the push to install solar panel on the White House (again) might not end well.  Although Jimmy Carter had solar panels installed in the 1970s, when Ronald Reagan took office in 1980, the panels were removed and have never been replaced.

  

  Jimmy Carter was the first President to install solar panels on the White House

  After a long push by a number of organizations to encourage the Obama administration to go solar, the federal government finally agreed to set aside security concerns in the name of clean, green energy.  But the promise to install solar panels on the White House may have been nothing more than a pipe dream.

  Specifically, the Department of Energy Secretary, Steven Chu, had promised that PV solar panels (for electricity) and a solar hot water heater would be on the roof of the White House “by the end of this spring.”  Sadly, even though the first day of summer was 2 years ago, the White House is still missing its solar panels.

  Even though solar panels have not yet been installed on the White House, the Obama Administration stated this week that the solar panels are still coming. Ramamoorthy Ramesh, director of solar energy technologies at the Department of Energy, wrote in a long blog post:

  The Energy Department remains on the path to complete the White House solar demonstration project, in keeping with our commitment, and we look forward to sharing more information—including additional details on the timing of this project—after the competitive procurement process is completed.

  Isn’t it high time that our government leads by example with respect to renewable energy?

  Residential Solar Panels Help Homes Sell Faster and for More Money

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  

  How solar affects the real estate market

  Is there a trick to selling your home faster and for more money?

  The recession of the past few years has definitely taken a bite out of home values, but residential solar panels can positively affect how fast you can sell your home, and what you might get in an asking price.

  Admittedly, some consumers are put off by the cost of solar panels, but in addition to helping you save on your electricity bills, home solar power boosts home equity.  In a 1998 study by ICF Consulting (“Evidence of Rational Market Valuations for Home Energy Efficiency,” www.icfi.com/Markets/Community_Development/doc_files/apj1098.pdf) it was determined that for every $1 you save on electricity by installing residential solar panels, property value increases by about  $21.  If you pocket a $500 annual saving after installing solar, you can expect your home to be worth over $10,000 more.

  In addition, a study by the National Renewable Energy Lab (NREL) confirmed that homes with solar power systems sell about 20% faster and for 17% more, based on a comparison with equivalent non-solar homes across several California subdivisions.

  The NREL study analyzed information from a San Diego, California real estate developer.  According to a related post:

  In a new residential subdivision, half of the homes were built with PV solar panels and solar hot water systems, while the other half didn’t include the solar features.  The 257 homes with residential solar panels sold within a year of going on the market – about two years faster than expected.  Perhaps even more impressive is the fact that the solar homes sold for $100,000-$200,000 more than their listing price (as much a $600,000 for houses were priced in the $380,000 to $500,000 range).

  You can review the entire the NREL study (PDF) for more information.  In the meantime, I’ll bet that residential solar panels are sounding like a good investment with a healthy ROI.

  Solar Power Increasingly Considered by Middle-Class Homeowners

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  

  More middle class homeowners are switching to solar power

  Despite the recession and news of sluggish, high unemployment rates, solar power is still increasingly considered by middle-class homeowners.

  There are plenty of good reasons for the demand for this renewable resource.

  First, solar panels have fallen in price over the past few years, and remain competitively priced.  Second, you can now purchase solar panels at many convenient locations (like Costco or major home improvement retail stores).  Third, government incentives and rebates are still quite generous, which help off-set initial costs.  And finally, there is growing concern regarding global climate change.

  Consider this statistic from One Block Off the Grid: 42% of upper middle class homeowners are considering installing solar panels in the next 5 years.  In a general, survey-based market survey – unrelated to solar panels -  One Block Off the Grid (1BOG) asked respondents from five regions in the United States – New England, Mid-Atlantic, South, Midwest and Pacific Northwest – “How likely are you to consider installing solar panels on your home sometime in the next five years?

  Respondents surveyed were asked whether they would consider installing solar panels on their home in the near future.  For the most part, these people were over the age of 35 with an annual household income of at least $100,000 and were evenly divided between men and women.  Of the 332 homeowners that completed the survey, 140 marked “maybe,” “probably” or “definitely,” which shows that more and more middle class homeowners are considering solar power in place of “traditional” energy sources.

  The number of people thinking about installing solar panels on their homes may be even higher, if the public was aware of the potential savings.  An astonishing 67% of the people surveyed underestimated the monetary savings possible by going solar.  With a better understanding of the costs and benefits of home solar panels, people considering the switch to solar power would be more likely to take action.

  What if you were surveyed?  How would you answer the question, “How likely are you to consider installing solar panels on your home sometime in the next five years?”

  Solar Roof Home Improvement Project this Summer

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  

  Installing a solar roof

  Looking for a way to cut your energy bill, as well as your carbon footprint?  Residential solar power is the way to go.

  So, why not take on a solar roof home improvement project this summer?

  The cost of home solar panels have fallen dramatically in recent years, and tax incentives and rebates are still available for people that install a solar energy system on their house.  For most property owners, a rooftop is the site that receives the most direct sunlight.  Solar roofs are popular among homeowners because they are efficient, easy to maintain, and do not take up space.

  There are several solar roof options to consider:  (1) solar electric photovoltaic (PV) panels; (2) solar roof shingles; and (3) solar thermal panels.  Each of these has benefits and drawbacks.

  With PV panels, UV sunlight is converted into solar electricity, which can either offset or completely replace grid-based power.  Solar electric photovoltaic panels are usually large and bulky.  There is definitely an aesthetic impact that affects the appearance of your home.  In addition, roof penetrations for brackets are required.  Depending on the size of your home and your energy needs, a residential solar arrays may cost between $7,500-$40,000.

  Solar roof shingles are the answer for homeowners who want to have a low-profile solar installation that minimizes impacts on appearance.  Instead of regular asphalt shingles, solar film-covered shingles may be installed, which blend in with other roofing materials.  They are an excellent example of “building integrated photovoltaics.”  No roof penetrations are required, and the solar shingles will last as long as regular roofing tiles.  Solar roof shingles generate clean, renewable electricity that will reduce or eliminate your power bill.  Solar roof shingles cost slightly more than PV panels, considering comparable wattage output.

  Solar thermal panels can also be used as part of a solar hot water system.  Instead of generating electricity, these panels heat water without grid-based power.  UV light that hits the panels starts a system that sends free hot water into your water tank.  A number of different solar hot water systems can be used, depending on your needs and the climate in which you live.  Solar thermal panels are usually less expensive than solar electric panels.

  If you want to go with a solar roof home improvement project this summer, you should have a professional inspection, quote and installation.  While you can try installing solar panels as a DIY project, you’ll get best results from a contractor.

  Why not enjoy the sun – both outdoors and inside with your solar electricity or solar hot water!

  What’s the Best Time to Install Solar Panels?

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  

  Solar panel installation in the summer

  Wondering about the best time to install solar panels?

  With summer here in the Northern Hemisphere, home improvement and construction season encourage many people to think about upgrades and improvements to their property.

  But is this the best time of year to go solar?  Summer offers both benefits and drawbacks for solar panel array construction.

  On the positive side, long days and drier weather make it easier to schedule solar contractors at your home.  If you are considering a DIY solar project, its always more beneficial to get up on the rooftop when the rains or other inclement weather make it dangerous to do so.  And, professional solar installers will have more time and availability in their schedule over summer months.  Some even work extended hours from 7 a.m.-7 p.m.

  The downside of installing solar panels during summer is that high temperatures can actually reduce efficiency.  It may be difficult to assess the efficiency of a solar array or even determine how much money it could save you in electricity bills until the weather cools in the fall.  In addition, as noted above, many people choose to undertake home improvement projects this time of year, which can make it difficult to schedule contractors that are available.

  Perhaps the most determinative factor in considering the best time to install solar panels is the timing of renewable energy rebates and other incentives.  Over the past few years, the cost of solar cells has gone down, while governmental incentives have been quite generous.

  We may be starting to see the beginning of the end, however.  Many experts are advising that the public funds are, or will be, running out.  That means that the best time to install solar panels is probably in the next 6-10 months.

  Thinking about going solar?  Now may be the best time!

  We all want lower solar panel costs, right?  Well, in Washington, D.C., new legislation has been introduced to help streamline local permitting of solar arrays, allowing property owners to go solar with less expense, hassle and delay.

  

  Proposed Federal Legislation to help lower solar panel costs

  The 10 Million Solar Roofs Act, a bipartisan proposal, would literally award communities that make it easier to obtain permits for solar installations with grants and subsidies.  Sens. Bernie Sanders (I-Vt.) and John Boozman (R-Ark.) hope that the proposed bill helps boost the quickly growing solar industry in the U.S., while encouraging consumers that would otherwise be wary of solar panel costs.

  In a press release, Sen. Sanders said:

  “This legislation will make it more affordable for families and businesses to install solar, by helping communities reduce the costs associated with solar energy permitting. … [The bill] sets strong targets for American solar energy production, to ensure we compete vigorously with China and Europe for solar energy jobs.”

  Solar panel costs have already fallen over the past few years as demand and production have risen, the cost of manufacturing materials has fallen, and tax incentives have helped defray investment required for the renewable energy resource.  The number of both rooftop solar panels and utility scale solar power plants has dramatically increased as a result.  Yet, only about 1% of all energy consumed in the U.S. is from solar power.

  The 10 Million Solar Roofs Act would address another component of the expense associated with solar panels -  the bureaucratic red tape that property owners must navigate in order to obtain permits for solar installation.  An industry document (PDF) from the Solar Energy Industries Association determined that a streamlined regulatory system for installing and permitting solar panels would help make solar affordable for 50% of American homes:

  The policy goal of supporting solar is to create the scale necessary to achieve grid parity, the point where solar stands on its own as an economic choice for millions of homeowners, without the need for subsidies. While solar equipment prices are falling, the total installed cost of residential solar is falling more slowly because of inefficient local permitting and inspection processes. It is appropriate and necessary for the Department of Energy (DOE) to address this problem because DOE has already built the tools to quickly streamline local permitting and inspection processes without sacrificing safety.

  The effect of current solar permitting costs amounts to a $1 billion tax on the industry over five years.  As a result, American solar manufacturers have a hard time keeping costs down, particularly relative to countries like Japan and Germany where there are zero permitting requirements for solar panels on homes.

  If the 10 Million Solar Roofs legislation passes, the average consumer can expect to save $2,500 in solar panel installation costs.

  5 Things That Affect the Cost of Solar Panels

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  

  What affects the cost of solar panels

  Thinking about residential solar power?  You might be worried about the expense of this renewable resource.  But there are ways to save money and also save energy while you go solar.

  In general, there are 5 things that affect the cost of solar panels:

  1.  Rebates and incentives.  Even though governmental tax rebates are not quite as generous as they were a few years ago, you can still save a lot on solar panels by tapping into local, state and/or federal incentives and rebates. Combined, you could pocket up to 80% of the retail cost of solar panels!

  2.  Current energy usage.  Its quite simple: the more electricity you use, the more solar panels you will need.  Reduce your overall energy consumption, and you won’t need to generate as much solar electricity!

  3.  Solar irradiation and UV exposure.   Consider your roof angle, any obstructions and shading, and the overall solar irradiation for your region.  You don’t necessarily have to live in a warm, sunny locale to tap into solar energy.  However, you do need to have optimum UV exposure, which is impacted by the angle of your roof, among other things.

  

  Save money with solar panels

  4.  Net metering.  You can literally turn back your utility meter with solar panels!  The way net metering works is that, when excess solar electricity is generated by your solar array, the energy is fed back into the grid for other consumers to use.  Then, when you need to draw on grid-based power overnight or on cloudy days, you get a credit for the power you contributed to the system.  Save even more!

  5.  Materials supplies.  The primary reason that solar panels cost so much less today than 5 years ago is the reduction in the cost of supplies required for manufacturing solar cells, including silicon.  In addition, solar technology is leading to increased efficiency of solar cells, which further reduces the cost of a solar array.

  Experts predict that the cost of solar panels will continue to decrease in the coming years.  However, governmental rebates and incentives may not be as generous as they are now in the future.  If you are thinking about going solar, now may be the best time!

  Community Solar Power With Power Purchase Agreements

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  Looking for a less expensive way to go solar?  You now have many options, including community solar power with power purchase agreements.

  

  Time to consider community solar power? (image by Joanna 8555 on flickr)

  Under some of these arrangements, you need not purchase or install pricey solar panels on your roof.  Instead, another entity will install and own the panels and you only pay for the solar electricity that is generated from them.  Its truly a win-win situation with the homeowner enjoying lower electricity bills without having to make a huge investment upfront.  The environment benefits too with reduced reliance on fossil-fuel based energy.  In fact, even your local utility has a stake in this when you help reduce demand on the grid at peak times.

  Solar panel leases are a type of power purchase agreement that can be implemented on an individual basis.  But, to save even more, you might consider community solar power shared with your neighbors, or even just other citizens in your area.  Options vary from state to state, but here are a few of the most newsworthy approaches to community solar power.

  In Colorado, we recently blogged about the new Community Solar Gardens Act that became effective in 2010.  The legislation allows groups of at least 10 subscribers to form an investor-owned utility, develop a solar electric system for the group and then share in the enjoyment of clean, solar electricity.

  If the community solar garden sounds like too much work, you can join with your neighbors to tap into the Clean Energy Collective in Carbondale.  This entity designs and installs solar power systems for joint ownership by homeowners.  Using remote metering, residents can enjoy net metering credits on monthly utility bills, too.

  Across the country in Massachusetts, another company called My Generation Energy, also designs and builds community solar power systems for groups of residents on Cape Code.  To date, two groups of residents have come together and formed limited liability corporations (LLCs) to benefit as a whole from the solar electricity generated.

  Even without the help of a company that is devoted to building and maintaining a community solar system, some residents are taking it upon themselves!  In Maryland, 35 homeowners in the University Park community formed their own LLC to develop, own and operate a 22 kilowatt solar power system on top of a church.  With tax credits, the return on investment for these people will be a short 6 years.  Over the life of the system, participants expect an 8% annual return.

  Do you know of any community solar power arrangements in your hometown?

  Solar Swimsuits: Photovoltaic Fabric

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  

  Solar Bikini keeps your devices powered at the beach

  File this one under the “you gotta see it to believe it” category.  Andrew Schneider has created a solar swimsuit out of photovoltaic fabric that is intended to keep your electronics running while you lounge at the beach or sunbathe by the pool.

  I know its hard to believe, but the solar bikini pictured here is covered with flexible solar cells (encased in plastic) and includes USB connections to power up your iPod or cell phone.  The solar panels convert sunlight into clean, portable solar power.

  As Paris Hilton might say, “That’s Hot.”

  Schnieder’s solar swimsuit, called the “iKini,” is selling for $200 and can be ordered now!  However, he admits that it is currently “more of a conceptual thing.”  The idea for the photovoltaic fabric-covered suits  was born in a NYU graduate school sustainability course.

  The solar bikini is covered with small solar panels, and there is a thin strap along the back that allows the energy generated from the top piece to flow down to the bottom part of the suit.

  No word on whether the solar swimsuit is comfortable or water-resistant.  And for those that are concerned about efficiency of solar panels, I’d have to guess that one would have to be careful not to get sunscreen on the suit, as well.

  Schneider says that he is also developing photovoltaic fabric swimming trunks that generate power to keep beer cold. A Peltier junction mechanism to will be employed to produce thermoelectric cooling and may also have a USB port, too.

  Floating Solar Power Plants

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  Floating solar power plants may be the answer to two of the biggest hurdles for utility scale solar power plants: (1) the need for large areas of land; and (2) costs related to maintenance of solar cells.

  

  Floating solar power plants: a renewable energy innovation

  Solar power technology developed through a partnership between Solaris Synergy from Israel and the EDF Group from France will allow solar power plants to be constructed over water.  Instead of building solar installations on natural lakes or over the ocean, industrial water basins in use for other purposes (industrial or agricultural) would be used instead.  This minimizes potential aesthetic and wildlife impacts, and also addresses the need for undeveloped land for utility power plants.

  Floating solar power plants can also use the water on which the panels are built for a creative cooling system.  As a result, solar arrays will include less expensive photovoltaic (PV) silicon solar cells, which need to be cooled down to minimize overheating. The team also worked to cut the costs associated with solar power by using a solar concentrator system with mirrors to increase efficiency of solar cells.

  Currently, a prototype is scheduled to begin operations in September 2011 at Cadarache, in the South East of France.  The water surface on which the floating solar power plant will be constructed is close to a hydro-electric facility and will be able to feed electricity generated into the French power grid.  The research team will assess performance and productivity of the solar plant through the seasons and at different water levels.

  By June 2012, the research will be complete and floating solar power plants should be ready to enter the market.

  United States Senators Pushing 10 Million Solar Roofs Act

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  Crossing party lines, three United States Senators joined forces to introduce the 10 Million Solar Roofs Act of 2011 this week.  The legislation proposed by Senators Bernie Sanders (I-Vt.), John Boozman (R-Ark.) and Jeff Bingaman (D-N.M.) would lower the cost of residential solar panels, as well as commercial solar installations, by streamlining the application and permitting process.

  

  Can new federal legislation encourage 10 million solar roofs?

  Some estimates show that such legislation could trim as much as $2,500 from the cost of solar panels.  This is the second time the 10 Million Solar Roofs Act has been proposed, following 2010′s failed attempt to get the law passed.

  The proposed 10 Million Solar Roofs Act of 2011 would tie into the Obama Administration’s SunShot Initiative.  Appropriations of $50 million each fiscal year from 2012 through 2016 would be invested to develop best practices for solar permitting.

  Senator Sanders commented in a press release:

  “As we lower the cost of solar energy and increase our use of solar, we can create hundreds of thousands of good-paying manufacturing and installation jobs in this country.  This bill also sets strong targets for American solar energy production, to ensure we compete vigorously with China and Europe for solar energy jobs.”

  The need to make solar power more affordable by reducing costs associated with the permitting of solar installations is not only about the environment.  Hundreds of thousands of green solar jobs would be created as well, if demand and use of solar increases nationwide.

  The spokesperson of the Solar Energy Industries Association (SEIA), Monique Hanis, commented:

  “We applaud the senator’s efforts. He’s been a long-standing supporter of solar. And we look forward to working with this bipartisan group of legislators.  A bill like this could go a long way to make it easier and less expensive to deploy more solar.”

  What do you think about the proposed new federal legislation to encourage solar panel installations?

  Solar Boat Battery Charger

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  If you are thinking about solar power in your life, why not start small?  There are a wide range of solar panel products that can be used to recharge just about anything with a battery, from cell phones to cameras.

  

  Solar boat battery charger

  A solar boat battery charger is a great, relatively inexpensive device that allows use of solar energy to avoid the disappointment of a dead battery when you go to use your boat.  Unlike motor vehicles, boat batteries are not used regularly and the charge can drain over days or weeks.

  But a small solar trickle charger can prolong the life of your boat battery without having to keep an unattended boat plugged in.  Whether you moor your boat at a commercial marina, or a private dock, a solar boat battery charger is convenient and safe.

  Exactly how much solar power will you need to keep your boat battery charged?  If your boat uses a 100-amp-hour battery, experts recommend a 5-watt solar panel.  This will allow for recharging inefficiencies that may occur via a cloudy day, and any extra capacity is safe for the battery if the water level is maintained in it.

  Any crystalline photovoltaic solar panel used to keep boat batteries charged should have at least 33 cells to produce adequate voltage to keep the battery fully charged.  Be sure to mount the solar panel for maximum sunlight exposure and avoid any shading, which will impact efficiency.  Common locations for solar boat battery chargers are on radar arches, on top of T-Tops and biminis, or deck-mounted.  Because heat reduces the output of solar panels, be sure to keep them raised to allow for air circulation.

  

  Solar panels keep this boat's battery charged

  You can find solar boat battery chargers at specialty marine stores, and also online at major retailers like Amazon.com.

  Solar Panels for RVs

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  With Memorial Day here, people are embarking on summer vacation adventures.  For those that enjoy traveling and camping in an RV (recreational vehicle), solar panels may be just the thing to use to keep your appliances running and your electronics charged.

  

  Solar panels for RVs keep your battery charged without the need for noisy, dirty generators

  Solar panels for RVs are more affordable than home solar panels, in part because the energy demands are lower in a small space.  Instead of relying on a gas generator, using energy from the sun to power your stove, television and computer while out in an RV is cleaner and cheaper over the long run.

  You can find a variety of solar panel kits on line and in major retailers like Lowe’s, Home Depot and Costco.  Experts can help you determine the number of panels and wattage you’ll need to keep you charged up.  The cost of solar panels for RVs ranges between $800-8,000, depending on the size of your RV and your daily battery drain.

  Simply set up your solar panels to face the sun and tap into solar energy while parked, or even on the road.

  Solar Powered Handbag is Attractive and Stylish

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  I’ve been blogging about solar power for nearly three years.  We’ve written about solar backpacks and solar purses.  But let me tell you – I have never seen a solar powered handbag so attractive and stylish as this one.

  

  Solar Powered Handbag is so stylish!

  Created by Diffus, the new solar handbag has…. can I say it… adorable photovoltaic (PV) cells adorning its exterior.

  According to the Diffus blog, the company worked with Swiss embroidery company Forster Rohner and the Alexandra Institute to create a bag that uses solar panels as a key design element.  One hundred small solar panels on the outside of the purse absorb UV light and convert it to usable power to recharge your cell phone or mP3 player right inside the handbag.  When you open up the top, integrated fiber optics light up to help you locate items with ease.

  The Diffus solar powered handbag is so stylish and practical, you may not ever carry another!  It is sized to carry daily planners, keys, cell phones and other items you need while on the go.

  The Diffus blog describes this amazing handbag:

  “The shape of the bag resembles the story between the relationship between the sun and moon – between light source and enlightened. Therefore the shape mimics an eclipse where the moon – the enlightened – interfere or interact with the sun – the light source. The surface is embroidered with an integrated combination of normal embroidery and conductive embroidery that is able to convey the energy harvested for the solar sequins to the rechargeable battery.”

  

  The Diffus solar powered handbag

  The designers of the Solar Handbag showcases use of efficient, textile-based solar cells.  When the bag is exposed to UV light, it can generate 2 watts of solar power, which can easily charge one of your mobile devices, even on cloudy days.

  Solar Powered Urban Chicken Coop

  Urban farming is on the rise with more people considering local food and trying to minimize environmental impacts.  I have several friends that own chickens and raise (quite tasty) eggs.  So when I found this solar powered urban chicken coop, I had to write about it!

  Shown at the International Contemporary Furniture Fair, the modernist solar chicken coop created by Raad is so sophisticated, the designers call it a “residence.”  This structure houses chickens in a comfortable setting so that they can comfortably produce farm-fresh eggs.  For time-pressed urban farmers, the coop itself is very easy to set up and assemble.

  Solar energy helps air circulate through the coop.  There are three levels inside to allow for bedding and food, a perch for roosting and private laying units.  If you own chickens, you’ll appreciate the easy cleaning with a slide out chicken run.

  Home Electric Car Charging Stations: Getting the Best Charge for Your Electric Car

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  

  Using a home electric car charging station

  Thinking about an electric car?  Already own one?

  Most consumers want to make sure they can adequately recharge their electric vehicle when its parked during the day and overnight.  Consider your home power situation and how to set up your garage to efficiently and easily “fuel” your EV.

  Home solar panels are probably one of the cheapest sources of electricity for your electric car, as your utility bills will not increase just because you are using more energy.  Moreover, use of solar power instead of grid-based electricity will help reduce high loads/demand in the evenings when many people are returning home from work, turning on televisions and preparing dinner.  Using solar panels instead of gasoline or fossil-fuel sourced electricity is the cleanest way to go.  Over the life of your EV, you can save thousands of dollars each year.

  Once you decide whether home solar power or grid-based electricity will be your source of energy, you’ll need to consider retrofitting your garage with a home electric car charging station and a 240-volt socket.  You can choose not to and simply plug the car into a standard 120-volt wall socket, but the recharging time will take twice as long.  Charging stations run about $2,000, however, including installations.

  Aside from cost, the biggest factor to consider is how far do you have to drive each way?  Without a charging station, a 120-volt socket will give you approximately 5 miles of driving for every hour of re-charging.  If you drive 40 miles round trip, you can charge up your electric car overnight – in 8 hours.

  Next question is whether there is a charging station at your work location.  Its convenient to top off your battery during the workday.  Some commercial property owners are installing solar panels on garages or shelters to generate power for EV charging stations on-site.

  Getting the best charge for your electric car will probably mean installing a charging station, connected to a 240-volt socket.  Home solar panels can reduce the cost of commuting significantly, as well as your carbon footprint.

  Palm Desert Sets the PACE for Solar Panel Financing by Local Government

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  Worried about the cost of solar panels?  How can you finance solar energy?

  

  Solar panel financing with PACE programs (image from U.S. Army Environmental Command on Flickr)

  One promising program is Property Assessed Clean Energy (PACE), which allows local government and private property owners to give low interest loans to people that want to go solar.

  In Palm Desert, California, the municipality is working to help local governments overcome obstacles from Fannie Mae and Freddie Mac to Property Assessed Clean Energy financing.  In fact, the city is voting to allocate $25,000 as funding for a non-profit education and advocacy organization, “Energy Independence America” to be operated by EcoMotion.

  The Palm Desert press release states (thanks to Jim Jenal):

  Palm Desert to Again Lead on Clean Energy Financing Kicks Off Formal PACE Advocacy Effort to Overcome Federal Obstacles Palm Desert, California, the city that spearheaded Property Assessed Clean Energy (PACE) financing in 2008, is leading the charge to overcome federal obstacles placed in the way of this popular program. Palm Desert has committed initial seed funding of $25,000 to EcoMotion to form a non-profit education and advocacy organization for PACE, called Energy Independence America, and is urging cities and counties throughout the country to get behind this important effort. Interested parties can request to be on the list for Energy Independence America updates.

  So-called PACE financing of solar panels through local government has been heralded as “one of the most innovative municipal finance programs in modern history,” according to The Harvard Business Review.  In the past 5 years, the programs had taken off in half the states in the U.S., but on July 6, 2010, the Federal Home Finance Agency (FHFA), caretaker of Freddie Mac and Fannie Mae, summarily  that it would no longer honor mortgages with PACE liens securing residential energy improvements.

  As a result, many PACE programs in the U.S. have stopped.  Even since Palm Desert and other municipalities have sued the FHFA, nothing has changed.  Yet, Palm Desert continues its efforts to get PACE off the ground and allow people that want to install solar panels to do so with government assistance.

  Last month, the Palm Desert City Council voted to support a nationwide effort to overturn FHFA’s administrative determination.  The program, called Energy Independence America, aims to “reach out to all stakeholders affected by FHFA’s decision, from public entities that benefit from PACE programs to the private homeowners who benefit from efficiency and generation improvements, as well as the manufacturers and contractors who install them.”

  Jim Ferguson, former Councilmember and Mayor of Palm Desert, is a key spokesman for Energy Independence America:

  “We are going to exert every effort possible on the judicial, legislative and executive branches of government so they see the short sightedness of preventing homeowners from spending their own money to cure our nation’s environmental and energy woes. We’ve had a huge outpouring of cities and states looking to Palm Desert to, again, take the lead on clean energy financing.”

  Its great to see Palm Desert setting the PACE for solar panel financing by local government.

  We think it only makes sense to showcase and utilize renewable energy at a natural family destination like a zoo.  After all, most zoos these days have explanatory exhibits discussing endangered animals, habitat and ways to cut your carbon footprint.

  

  Solar Panel Parking at the Cincinnati Zoo

  With an eye on nature, why not utilize one of the most natural forms of energy available?

  At the Cincinnati Zoo, SolarWorld solar panels provide shade and generate solar electricity to off-set the impact of grid-based power.  These state-of-the-art parking lot canopy systems include about 6,400 solar panels manufactured by SolarWorld (based right here in my home state of Oregon).  SolarWorld is the largest United States manufacturer of solar technology.

  This largest urban solar array accessible to the public is 1.56 megawatts (MW).  The canopy system allows for shaded and sheltered parking stalls, and utilization of rooftop space to tap into abundant free solar energy.  SolarWorld is excited about the new solar canopies and large-scale solar project in Cincinnati.

  Raju Yenamandra, VP for sales and business development in the Americas, enthused:

  It’s gratifying – and fun – to see the technology that SolarWorld pioneered for so long using American labor on U.S. soil star in this Midwest showcase.  When I started my career, solar was a novel but promising power-generation alternative to fossil fuels. Since then, our technology has built a long track record of reliability. Now, this project signifies its arrival at center stage of American life.”

  The solar panel system consists of 15 arrays and was developed, engineered and installed by Melink Corp.  The zoo parking facility is about 4 acres in sice, with solar panels covering 800 of the 1,000 parking spaces in the Cincinnati Zoo’s main parking lot.  The solar electricity generated by the panels will offset 20% of the zoo’s power needs, saving millions of dollars over the life of the system.

  Solar Power for the Home: Easier and More Affordable

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  Thinking about solar power for the home?  If you are like most people, there are two primary concerns: the cost of solar panels, and whether they will be a big hassle.

  

  Solar power for the home (image by joncallas on Flickr)

  Fortunately, home solar power is becoming more affordable each year.  Technology is improving and with growing demand, manufacturing process can be streamlined to produce more units at a lower price.  Add in generous government incentives, and solar energy could be well within reach.

  There are two types of solar panels for the home – PV panels (photovoltaic cells that absorb sunlight and convert it into electricity) and solar thermal panels, which heat water for domestic or commercial uses.  Depending on the type and size of solar panel array you desire, average prices range from $8,000 – $40,000.  The more panels you have, the more you can trim your electricity bills.

  Solar power for the home has been described as “install it and forget it.”  Maintenance is usually minimal, usually involving trimming vegetation that shades the panels, or removing snow.  While there are a number of DIY solar videos, your best bet is to hire a professional for the installation.  That way, if something goes wrong, you can look to the company for assistance.

  So, find a sunny, south-facing portion of your roof and start tapping into that ample resource that is just waiting to be used.  Solar power for the home is easier and more affordable than ever.

  Solar America Cities Conference Addresses Acceleration of Solar Energy

  Solar America Cities

  The 4th annual Solar America Cities conference was held last week in Philadelphia.  Representatives from 25 cities across the United States attended the event which addressed acceleration of solar energy, as a clean power alternative.  The Solar America Cities program was established by the U.S. Department of Energy in 2007.

  Before we can encourage more people to switch to solar power, barriers to adoption must be identified and addressed. Financing is one obvious barrier.  As solar technology continues to improve system components, pricing may drop even further.  Alternatives to purchasing a solar system outright include solar leases and property assessed clean energy loans.

  Another barrier to more widespread use of solar power is the long and often expensive local permitting process to get approvals required to install solar panels.  At the conference, Department of Energy Acting Under Secretary of Energy Dr. Arun Majumdar announced a Request for Information (RFI) for a solar challenge designed to address permitting issues, potentially including adoption of a standardized permit system.

  Currently, the cost of obtaining permits from cities and counties to install solar panels averages $2500 per system.  What property owner wants to spend that much additional money on an already expensive energy upgrade?   With a standardized permit system, the equivalent of a $1 billion solar subsidy over five years could be realized.

  Experts expect success with the new solar challenge through Solar America Cities.  Since the program’s inception, solar energy costs are lower with hopes to further reduce the costs 75% by the end of the decade, through the DOE SunShot initiative.

  Tags:    [edit]

  Electric vehicles (EVs) are hitting the mainstream these days.  With solar panels generating clean, free electricity, many agree that solar powered electric vehicles are soon to represent transportation of the future.

  

  Solar Charged EVs (image from ecofriendlymag.com)

  So what about solar charged electric vehicles?  According to SolarChargedDriving.Com, one of the first Nissan LEAF owners in the UK, Alan Weeks, explained why solar energy is for him and his electric car.

  Since Weeks purchased his Nissan LEAF, he’s driven it more than 600 miles. In addition to politics, the UK solar-charged driving pioneer enjoys gardening and “attempting to grow tropical looking plants such as palms, bananas and bamboos in a temperate climate.”

  The new wave of electric vehicles promises clean and even free fuel to power your car.  With gas prices in the United States at or over $4.00/gallon, many consumers are looking to ways to save energy and money.

  Electric Vehicles are everywhere these days.  Switching to EV means you can save at least $50 per month in fuel costs.  Tap into solar energy and the money left in your budget can easily reach over $100 each month, or $1200 her year!

  Solar Panels on Commercial Buildings Generate Free Electricity

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  In general, many buildings have a very valuable resource that is overlooked:  rooftop space.  This untapped real estate is a prime location for solar panels on commercial buildings, which can generate free electricity and save thousands of dollars each year.

  

  Installing solar panels on a commercial building rooftop

  In the past, the decision whether to go solar required financial analysis to determine whether the return on investment would be sufficient to justify the cost of installing solar panels.  Today, however, commercial building owners (and homeowners) can go with a solar lease agreement that allows them to start enjoying solar electricity immediately with no money down.

  Under a solar panel lease, the building owners merely “rent” or “lease” the panels rather than purchase them outright.  A monthly fee, which is lower than the current cost of electricity is assessed, and the owner does not have to worry about repair, maintenance, or even insurance in most cases.   The additional savings in monthly utility bills is pocketed by the building owner, and the risk of future skyrocketing rates through utility hikes is eliminated.

  Generally speaking, a commercial building rooftop of at least 2,500 square feet in size, which faces south, or is unobstructed and flat can host a 30 kilowatt (kW) solar panel array.  A solar power system of that size is guaranteed to generate about $6,000 of free solar electricity each and every year.  And, with a solar lease agreement, the building owners do not need to finance the approximately $125,000 cost of purchasing the panels themselves.

  Neal Uppal, president of Solar Topps, based in Tempe, Arizona, observes:

  “At first, solar lease agreements are hard to believe because of the price and increased cash flow, but once CPAs examine the financial spreadsheets, more than 90% of commercial customers to decide to go solar because it costs them nothing to save money and reduce their monthly electric bill.”

  Today, many companies offer solar lease agreements.  Building owners and managers can make an informed selection based on the products used for the solar array itself (panels, inverters, racking), the method of installation, the expertise of the installation company, the price, talking to existing customers, and the terms of the proposed contract.  Have your attorney review any solar panel lease agreement before signing.

  With solar panels installed on a commercial building rooftop, savings start adding up immediately.  Even after solar lease payments, many owners realize savings of at least $2,500 a year!

  Net Zero Solar Powered Homes

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  Would you live in a net zero solar powered home?  Just what does that mean?

  

  Zero Energy Homes are popular among home buyers

  For construction companies, homeowners looking to save money and the solar industry, net zero solar powered homes are good news all the way around.  First, they address a sagging housing market that is slow to recover.  This is because they help homeowners save a ton of money by producing as much energy through solar panels as is required to run the household.  That adds up to savings of about $2000 per year for the average home!

  Finally, for solar power companies net zero solar powered homes help demonstrate to the public the efficiency and practicality for turning to this renewable resource.  That means more sales of solar panels in the future!

  

  Building net zero solar powered homes

  New home construction companies around the United States are getting into the net zero solar powered homes market.

  In Tuscon, Arizona, you can get a zero energy home starting at $140,000, constructed by Meritage Homes.  Solar panels are included in the price.  You can also find Mertitage Homes net zero energy homes in California, Nevada, Colorado and parts of Texas.

  Beyond Meritage Homes, other builders are looking to lure buyers with net zero solar powered homes.  Dell Webb in Phoenix Arizona includes solar panels and energy efficiency upgrades in its Sun City communities.

  If you are looking for a home in Southern California, KB Homes includes solar panels on the rooftop at no additional cost in some of its communities.

  Perhaps not surprisingly, you can find solar powered homes in Florida, as well.  Shea Green Certified Homes are constructed with a standard 3 kW solar panel system.

  We love how home builders are tapping into solar power to help sell homes and save homeowners money!

  Solar Homeowners Get Higher Prices for Property Sales

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  

  Solar panels boost home sales

  We’ve blogged about it before, but its worth discussing again just because anything that can increase the sale price of a home is welcome news these days!

  Solar homeowners get higher prices for property sales.  In other words, if you install solar panels on your rooftop, the feature could help you sell your home, depending on its age and location.

  A study published by the Lawrence Berkeley National Laboratory, supports the theory that solar powered homes enjoy higher resale prices than comparable “non-solar” properties in the neighborhood.

  With solar panel prices averaging $4-6 per watt in California, an entire residential rooftop solar panel system can run approximately $15-20,000.  Local, state and federal rebates and incentives can lower that price, however.  Most solar power systems have a lifetime of 25-30 years, so if you sell your home before you reach your return on investment (the point at which you break even on utility savings, or approximately 7 years for most homeowners), you can still recoup the costs of your solar installation.

  Interesting, the study found that homes with existing solar panel systems sold for even more than new homes constructed with solar panels.  Don’t forget that, for every $1 you save in annual electricity costs with solar power, the value of your home increases by $20.  That means, a saving of $500 (less than $50 per month) can quickly translate to a $10,000 boost in home equity!

  If you are thinking about selling your home in a few years, now just might be the time to install panels because solar homeowners get higher prices for property sales.

  Save With Solar Hot Water

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  

  Solar hot water panels installed on a home

  One of the most affordable ways to switch to solar power is with a solar hot water system.  Instead of generating electricity, solar thermal panels heat water using sunlight, no matter what the temperature is outside.  Solar water heating is perfect not only for residences, but also commercial uses including hotels, car washes, nurseries and even breweries.

  These systems are also ideal for heating swimming pools and spas.  In fact, during our recent visit to the sunny desert Southwest, I wondered why more properties did not rely on solar thermal panels for outdoor water recreation.

  A lot of energy is required to heat water for washing dishes, laundry and bathing.  With a solar hot water system, hot water is “free,” and much less expensive.  You’ll watch your electricity or natural gas bills drop dramatically after installing solar water heating.

  Solar hot water systems do require an initial investment, but property owners report savings of 50-80% on their energy bills as a result.  Not only that, but you don’t have to worry about rising utility costs over time.  Your solar hot water will always cost the same after installation…. free!  Solar thermal panels also are eco-friendly, with no greenhouse gas emissions.

  While there are a number of DIY instructional videos and websites on the Internet, most people recommend hiring an expert to help you both determine the type of solar hot water system to install and to actually perform the installation.  Costs of solar hot water range from $500-$10,000 for homeowners, depending on the type of system and other requirements.

  Solar Group Discount Buying Through One Block Off the Grid Expands into Three United States Markets

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  

  Solar group discount buying program expands into new U.S. markets

  Great news for homeowners considering installing solar panels!

  This week, the solar group discount buying company, One Block Off the Grid, announced its expansion into new markets in Massachusetts, Maryland, and California’s Central Valley.  People in these areas can now join the lucky folks in New Jersey, Long Island, New Jersey, the Philadelphia metro area, Los Angeles, San Francisco Bay Area, and Atlanta in taking advantage of 1BOG’s awesome services and leveraging opportunities.

  One Block Off the Grid connects property owners in a given region that wish to install solar panels and negotiates group discounts for solar on their behalf.  Participants often enjoy reduced price solar panels about 15% below market rate, in addition to local, state and federal solar energy rebates and incentives.  The cost savings apply to both equipment and installation of solar panel arrays.

  One Block Off the Grid CEO and founder Dave Llorens commented on the recent expansion and what it means for potential customers:

  “We’re thrilled to bring group deals on solar to so many homeowners, especially in states like Massachusetts where electricity is pricey and getting pricier.  Our approach is to take the hassle out of going solar for everyone involved.  For homeowners, we find the panels, vet the contractors, and wrap it up in a nicely discounted package.  On the installer and manufacturer side, we offer access to a widely varying residential market that is often disjointed and difficult to reach.  Overall, we’re helping green the country.”

  In addition to solar group discount buying services, One Block Off the Grid helps homeowners learn about the benefits of solar panel and connect them with reputable solar installers – so you don’t have to worry about the company you’re doing business with.  Group deals typically last 90 days.

  Llorens stated that the recent expansion of its solar group discount buying program was into markets where grid-based electricity is expensive and there are strong incentives to go solar. Yet, he hinted at future markets opening up:

  “But we see room for bigger things, because increasingly going green is the new norm.  People are starting to understand the economic benefits of green choices more deeply in addition to the environmental and public safety benefits.”

  1BOG also offers solar leasing options in Massachusetts, Los Angeles, and New Jersey.  Under a solar panel lease, homeowners do not own the solar panels themselves, but pay a monthly fee for the solar electricity generated by the system, which is lower than their current utility bills – and not subject to rate increases over the years.

  One Block Off the Grid is offering solar group deals in Maryland, Massachusetts, Long Island, and New Jersey, as well as the Philadelphia metro area, Los Angeles, San Francisco Bay Area, Atlanta, and California’s Central Valley.

  Solar panels installed at Oceanic Time Warner Cable in Hawaii

  When you think of Hawaii, what’s the first thing that comes to mind?  For most people, its probably the warm sunshine.  Given ample sunny days, it only makes sense that property owners in Hawaii rely on solar energy – especially given the high cost of grid-based electricity.

  Last week, Oceanic Time Warner Cable unveiled a new solar panel system at Miliani Tech Park in Hawaii.  The 856 kilowatt (kW) installation, including PV solar panels on two buildings and five solar parking canopies, was designed and built by Chevron Energy Solutions.

  Tioga Energy was brought in to help put together the financing for the solar panel project, and it will own and operate the system.  A quarter of the cost (approximately $1.25 million) will be covered by Hawaii taxpayers, while 30% ($1.5 million) will come from the federal government.

  And Oceanic Time Warner?  It entered into a power purchase agreement with Tioga Energy under which OTW does not pay for or own the solar panel system.  Tioga Energy will charge the company for the electricity generated by the panels over a 20-year period, at a set rate lower than grid-based electricity.

  That’s what we call going green and saving green with solar power!

  Generating Solar Energy Without Solar Cells?

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  Solar power is enjoying a surge of interest lately, due to the nuclear crisis in Japan, rising gas prices and concerns over global climate change.  Yet, the cost of solar still deters some people from converting from grid-based electricity.

  

  Solar energy is all around us - can we capture it without solar cells?

  What if it was possible to generate solar energy without solar cells?  In other words, could we harness the power of the sun for our use without having to pay for bulky PV solar panels?  According to a recent Forbes Blog post by Alex Knapp, solar technology could take a big step forward relying on breakthrough research at the University of Michigan.  Using magnetic properties of light at just the right intensity, Professor Stephen Rand and his associate, William Fisher, have discovered electrical voltage can be generated without needing solar cells.

  Light has electric and magnetic components. Until now, scientists thought the effects of the magnetic field were so weak that they could be ignored. What Rand and his colleagues found is that at the right intensity, when light is traveling through a material that does not conduct electricity, the light field can generate magnetic effects that are 100 million times stronger than previously expected. Under these circumstances, the magnetic effects develop strength equivalent to a strong electric effect.

  “This could lead to a new kind of solar cell without semiconductors and without absorption to produce charge separation,” Rand said. “In solar cells, the light goes into a material, gets absorbed and creates heat. Here, we expect to have a very low heat load. Instead of the light being absorbed, energy is stored in the magnetic moment. Intense magnetization can be induced by intense light and then it is ultimately capable of providing a capacitive power source.”

  What makes this possible is a previously undetected brand of “optical rectification,” says William Fisher, a doctoral student in applied physics. In traditional optical rectification, light’s electric field causes a charge separation, or a pulling apart of the positive and negative charges in a material. This sets up a voltage, similar to that in a battery. This electric effect had previously been detected only in crystalline materials that possessed a certain symmetry.

  What this all means is that one day we may not need expensive semiconductors to capture solar energy.  Instead, solar manufacturers could simply use ubiquitous, cheap materials like glass or transparent ceramics.

  This solar technology is still in the conceptual stage, and may take years before it can be reliably used for everyday applications.  But perhaps the promise of cheaper solar power is worth the wait.

  Solar Panels Keep Traffic Lights Green

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  

  Solar panels provide electricity for the blinking yellow light on a traffic sign

  Over the past few years after starting this blog, I have been noticing more and more solar panel installations to power blinking yellow lights on directional signs, warn drivers of changing conditions or road closures and even keep street lights on.

  But what about regular traffic lights?  Wind turbines and solar panels can help keep them “green,” as well, using research of a team at the University of Nebraska-Lincoln.  Not only will solar and wind power be used to operate traffic lights, but excess electricity generated would be fed into the power grid, significantly reducing costs for taxpayers through energy credits from utility companies.  The Energy Plus Roadways project is funded by a $1 million grant from the United States Department of Transportation.

  Consider this: It currently costs the City of Lincoln, Nebraska almost $1 million annually to power its streetlights and $72,000 for traffic signals and signs.  If the approximately 300,000 signalized intersections in the U.S. used solar panels to operate traffic lights the savings would nearly reach $50 million each year.  In addition, solar powered traffic lights would reduce greenhouse gas emissions and create green-collar jobs.  If the region experiences an overcast day and/or calm winds, traffic lights will still operate because the system is connected to the grid.

  So, in essence, solar panels and wind turbines keep traffic lights “green,” not only by producing clean electricity for their operation, but also by saving taxpayers money on utility costs.

  I’d say let’s give this project a green light!

  Solar Power to Help California Reach Goal of One-Third Energy from Renewables by 2020

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  Earlier this week, U.S. Department of Energy Secretary Steven Chu was present at the announcement of California’s goal to generate 1/3 of its energy needs with renewable energy, including solar power, by 2020.  In fact, the USDOE itself announced a $1.18 billion loan guarantee to SunPower Corporation to develop a 250 megawatt (MW) solar power plant called the California Valley Solar Ranch.  With projects like this, solar power should help California reach its renewable energy goals.

  

  California Valley Solar Ranch

  The California Valley Solar Ranch will be designed, built, operated and maintained by SunPower, with the groundbreaking to occur later this year.  The solar power plant itself will be owned by NRG Solar.  The utility scale solar project will be comprised of photovoltaic (PV) solar panels and will be one of the largest PV solar power plants in the world when completed.

  Solar electricity generated at California Valley Solar Ranch will be sold to one of California’s largest utilities, Pacific Gas and Electric Company.  This project, combined with the 392 MW Ivanpah Solar Electric Generating System, will produce enough clean solar power for 240,000 homes in California.

  All of a sudden California’s goal of generating 1/3 of its energy from renewable energy resources by 2020 doesn’t seem that far-fetched!

  Solar Panels Financed by Local Government in Central Oregon

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  

  Solar panels are more affordable with local government loans in Oregon

  In rural Pendelton, Oregon, the farm and ranch town hopes to blaze a new Oregon Trail toward clean renewable energy.  The city is offering no-interest loans for solar panels, as well as a group-buy discount program.

  The City of Pendleton had two funds in sewer-related reserve accounts.   City manager Larry Lehman said, “why not put that money to better use?”  So, the City borrowed from the accounts to offer no-interest loans for solar panels of $9,000 each.

  Residents repay the loan over four years, which is tied to their tax returns in the spring – when they receive refunds of state and federal renewable energy tax credits.

  The City expects that it will cost only $10,000 in lost interest over four years, and the number of residents relying on solar power for their energy needs will continue to rise.  In 2010, more than 50 households and businesses in the small, rural community installed solar panels.  The City has an additional 75 loans available to residents in 2011, and it reserved $1 million to help businesses that are considering solar panels as well.

  One resident, Ken Abbott, took advantage of the group-discount program in which a number of buyers are pooled together to receive lower installation costs.  He estimates that the $14,500 system on his home will end up costing him only $3000 after tax credits and lower utility bills.

  Keith Knowles of LiveLight Energy, the solar contractor hired by Pendelton commented:

  “Its crazy that a rural community with conservative agricultural roots would take this on.  Or maybe it isn’t crazy in a community where they make their living on nature and the power of the sun.”

  The solar panel rooftop systems will offset about 1/4 of a home’s electricity usage, but savings will increase over time as utility rates go up each year.

  Grape Solar home solar kits right at your local Costco!

  Looking for a convenient place to buy solar panel kits and home solar power systems?  Why not at your local Costco Wholesale store?

  This week, Grape Solar announced that has entered into a business arrangement with Costco to sell home solar panels in its self-service warehouse facilities and online at www.costco.com.  You can find the solar panel kits on the page entitled, “Hardware – Generators & Backup Power.”

  The Eugene, Oregon-based solar manufacturer is looking to expand its customer reach.  President of Grape Solar, Ocean Yuan, enthused about the new business arrangement and the possibility of making it easier for property owners to switch to solar power:

  “For the first time, a leading retailer with numerous locations, quality recognition and tens of millions of loyal customers has made it possible for end users to buy high-quality solar products at great prices and have the products delivered directly to their homes in a matter of days .”

  Originally, Grape Solar and Costco tested sales markets in Costco Warehouses located in Washington, Oregon, California, Arizona, Pennsylvania, New Jersey, Delaware, Hawaii, and Puerto Rico.  Recently, the program expanded to Texas, Alabama and Florida, and many more markets will soon open up to offer quality, affordable solar panels for homeowners.

  If you are a member of Costco, you can choose between a variety of solar power systems at reduced members-only prices: 880W, 2300W, 3680W or 5060W.  Grape Solar products are ready-to-install solar panel kits.

  The Home Solar Power kits available at Costco are easy to install, grid-tied systems that include Grape Solar panels, inverters, and racking systems. If you find you need more solar power, you can add on additional panels to increase the size of your system very easily.  With the grid-tied solar systems, consumers can use net metering to sell back excess solar electricity to the utility and get credit for the times that they need to draw on the grid for power.

  Grape Solar panels come with a 25-year warranty on power output and a 10-year warranty on materials and workmanship. The inverters have a 10-year warranty and so do the racking systems.  Be sure to save your receipts too because the home solar power kits are eligible for federal, state and local rebate and incentive programs.

  SolarCity solar panels to be installed on City of Sacramento buildings

  Last week, the City of Sacramento, California approved a new plan with SolarCity® to install more than 8000 solar panels on municipal buildings.  The 1.9 megawatt project will be the largest solar power project undertaken by the capital city of California.

  Under the contract, SolarCity will finance, install and maintain the solar installations.  This means no cost to taxpayers up front, but the energy savings will immediately start adding up.  The solar panel arrays are estimated to generate about 2.6 million kilowatt hours (kWh) of clean electricity in the first year, or the equivalent of power for 250 homes.

  Mayor Kevin Johnson enthused about the solar panel project:

  “This project is a triple win for Sacramento—it will save taxpayers money by lowering the City’s energy costs, reduce pollution by generating renewable power, and create more local jobs to install the panels.  It’s our goal to become a greener city and generating clean energy on our facilities is keeping with that commitment.”

  The four sites on which solar panels will be installed include:

  • City Hall in downtown Sacramento
  • The building at 300 Richards Boulevard that houses the police department and building and planning offices
  • Corporation yard on Meadowview Road that houses the City’s sanitation fleet and other services
  • South Area Corporation Yard off Fruitridge and 28th Street.

  Again, there are no upfront costs for taxpayers.  The City will purchase solar electricity generated by the solar panels from SolarCity pursuant to a power purchase agreement (PPA).  This power will cost less than electricity from the grid, and is also much cleaner!

  Common Solar Power Definitions

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  When it comes to solar energy, sometimes it can be difficult to understand the various technical references.  We found a guide to common solar power definitions that can help anyone that is considering the possibility of going solar.

  

  A guide to solar power definitions

  1.  Photovoltaic (PV) module: Also known as a solar panel, a PV module converts energy from the sun into direct current (DC) energy.  You will need an inverter to convert it into usable AC (alternating current) in your home.  PV modules come in varying wattages and sizes. Typical PV modules used on home installations are 200 watts and about 14 square feet.

  2.  PV solar array: This term refers to a number of PV modules wired together.  If you have 5 x 200 watt PV modules, you have created a 1,000 watt PV solar array. Typical array sizes range from 2,000 to 5,000 watts.

  3.  Inverter: Mentioned above, this component of a solar power system converts DC electricity into alternating current (AC) electricity. A 3,000 watt inverter will output 3,000 watts of AC electricity given enough PV input. Typical inverter sizes range from 2,000 watts to 7,000 watts.

  4.  Grid-tied solar system: A solar electrical system composed of a PV solar array and inverter, which are connected to and interact with the utility grid. Other devices called over current protection devices or OCPD are used for safety. Energy from the PV array goes to household loads first, and any extra power is stored on the utility grid through net metering.

  5.  Kilowatt hour (kwh): One kilowatt (1,000 watts) for 1 hour = 1 kilowatt hour. Your  utility company charges by the number of kwh you use.

  

  Common solar power definitions can help you make sense of solar energy systems

  6.  Daily energy requirements: When you install a PV solar array, you could be generating most, if not all, the energy your home needs. Look at your utility bill or call your utility company to determine your energy use in terms of kilowatt hours per day or kwh/day. Use the average kwh/day for the last 12 months to account for seasonal variations in energy consumption.

  7.  Shade-free space: PV solar modules need direct sunlight to produce electricity. Shading from trees or other adjacent buildings will affect efficiency.  Your PV array must be located where it will receive direct sunlight between 10 a.m. and 3 p.m.

  8.  Project budget: Solar electric systems start at around $5K but most fall in the $20K to $40K range. There are federal and state incentives and rebates to take advantage of that will significantly decrease out of pocket costs. It may not be possible to produce 100% of the energy you use and many systems are supplemental, producing as much as space and/or budget allow.

  If you are thinking about home solar panels, consider these calculations for system size and cost:

  System size in kilowatts (kw) = (kwh/day) / 5 hours (peak sun) x 1.43 (system losses)
  Step 1: Divide average kwh/day by number of hours of peak sun, or (kwh/ay) / 5
  Step 2: Multiply by 1.43 to account for system losses due to friction, heat, and other inefficiencies.

  Example: What size system is needed to produce 20kwh/day?

  20kwh/5h = 4kw
  4kw x 1.43= 5.7kw
  5.7kw = system size to produce 20kwh/day assuming 5 peak sun hours

  System cost = system size x $7,000 to $9,000
  Step 1: multiply system size by $7 for competitive system cost installed
  Step 2: multiply system size by $9 for conservative system cost installed

  Example: How much would a 5.7kw system cost?
  5.7kw x $7,000 = $40,040 = competitive system cost
  5.7kw x $9,000 = $51,480 = conservative system cost

  Are there any other solar power definitions that leave you wondering about whether to go solar at your home?

  China to Trade Nuclear Power Targets for Solar Energy

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  Watching the nuclear disaster in Japan unfold has apparently had an effect on China.  According to Bloomberg, the Nation Development & Reform Commission in China announced it will trade some of its nuclear power targets for solar energy.

  

  China will be developing more solar power plants in place of nuclear

  Originally, China had planned on 80 gigawatts (GW) of nuclear power to be developed by 2020.  Now, it is said to be shifting its energy planning to solar power, to increase the projected 20 GW of solar to a higher percentage.

  While the debate continues regarding the safety of nuclear power plants, China doesn’t want its country to be the next test case.  Existing plants and how future power plants are built to withstand earthquakes are big considerations.  Particularly since there is no threat of a “solar meltdown” from a PV panel power plant, which leads many to conclude that solar is safer than nuclear energy.

  Factors Affecting Cost of Solar Panels

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  

  What factors affect solar panel costs?

  If you are looking to save on energy costs, you might be considering solar power.  But many homeowners are concerned about factors affecting the cost of solar panels.  Retail costs range between $5,000-$25,000 for a solar array to power the average home.

  While solar used to be a very expensive way to power your home, costs have fallen dramatically in recent years.  In addition, there are a number of government incentives and rebates for people who install solar panels on their rooftops.  But you can cut costs for solar by taking these considerations into account:

  1.  Current power usage.  If you can reduce energy consumption with efficient appliances, lowering the thermostat, washing in cold water and turning off lights, you’ll save money and need fewer solar panels.

  2.  Can you work with the local utility? See about feed-in-tariffs and net metering.  Excess energy that you generate can be fed back into the grid to reduce your bill when and if you draw on grid-based power.

  3. Timing is everything.  Just as with any other major consumer purchase, consider when to buy your solar panels to maximize sale prices and help manufacturers reduce inventory.

  4.  Compare prices and quality.  Sure, you might save a few bucks by going with cheap solar panels, but what kind of quality are you getting?  If you are going to save much on your energy bills with low-cost panels, then investing a bit more upfront probably makes more sense.   Read consumer reports, comments on websites (like this one) and be a wise customer!

  Solar Parking Lot Created by Ted Turner in Atlanta

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  One of the best ways to convince people to change to renewable energy resources is with a solar demonstration project.  So why not take it “downtown” with a solar parking lot?  In fact, why not in the most visible, sought-after parking facility in Atlanta, GA?

  

  Luckie Street Atlanta, GA

  Ted Turner has created the “Luckie Street Solar Project” on a site adjacent to his headquarters in Atlanta.  Solar panels have been installed in the first phase of the solar parking lot site on 2-acres.  In late 2010, Mr. Turner stated:

  “I wanted to do something solar right here in Atlanta as a demonstration project.  It is an experiment and demonstration project. When the whole thing gets done, it’s going to power the building and the restaurant.”

  The parking lot is across Luckie Street from the Tabernacle performance venue and includes 14 large canopies of solar panels that cover the asphalt parking lot, manufactured by First Solar.  In the second phase of the solar parking lot project, 11 additional solar panels from Suniva, Inc. will be incorporated.

  Not only will the solar energy generate power for the lighting of the parking lot, but solar power to recharge electric cars will also be available.  With shading from the installed solar panels, the heat-island effect of the lot is diminished.

  The solar parking lot fronts Centennial Olympic Park Drive overlooking the park.  Turner Enterprises will collect data on the solar output of the panels to learn more about the possibilities of using solar energy in the South.  When both phases of the soalr demonstration project are completed, the total capacity will be about  200 kilowatt hours (kWh).  The clean solar electricity generated by the solar parking lot will offset about 82 metric tons of CO2 emissions each year (burning 9,200 fewer gallons of gasoline).  The solar parking lot created by Ted Turner is the largest solar project installed in downtown Atlanta.

  Rooftop Solar Panels Could Power 100% of Los Angeles

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  

  Rooftop solar panels could power L.A.

  When it comes to solar power, many believe that distributed generation installations (that is, solar electricity generated right at the source that will use it) makes more sense and is more efficient than utility scale solar power.  In sunny Los Angeles, a new study confirms that rooftop solar panels could power 100% of Los Angeles.

  The study was released by the University of California at Los Angeles (UCLA)’s Luskin Center for Innovation.  Its major conclusions show that residential solar panels could completely offset the need for grid-based electricity, particularly during hot days when energy demands are high.

  Considering ample roof space on L.A. homes, rooftop solar panels could generate 19,000 megawatts (MW) of energy.  That is more than enough to run A/C, refrigerators, televisions and much more!  On an average day, the City uses about 5,500 megawatts of power.  When the mercury rises, energy needs do too.  Hot days increase power consumption by about 1/3, up to 6,177 MW throughout the city.

  With rooftop solar panels potentially powering 100% of the city of Los Angeles, hope rises that it will be able to meet its ambitious goal of weaning itself off of fossil fuel sources by 2020.  Experts believe that such a plan is far more eco-friendly than utility scale solar power plants in the Mojave Desert.

  Building Integrated Photovoltaics: Combining Solar Power and Construction Design

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  Combining solar power and construction design is becoming the wave of the energy future.  Its a relatively straightforward concept, with a fancy name: Building Integrated Photovoltaics (BIPV).

  

  A really cool BIPV design using solar panels for awning materials

  Quite literally, BIPV is the incorporation of solar energy generating materials into roofing materials, siding, solar paint and even solar windows.  Instead of bulky PV panels sitting on your rooftop, you could have sleek solar shingles that blend right into profile of your home.

  The act of generating renewable energy right where its needed – as opposed to having it travel across the grid – is called distributed generation.  There are many that tout its benefits over clean, utility-scale solar power because its more efficient and cheaper for the user of the solar energy.

  Thin-film solar technology is one of the biggest factors for building integrated photovoltaics.  But the concept is still new, and kinks are being worked out before the general public can regularly draw on solar energy generated by thin-film solar.   And, while there is potentially a broad range of building materials into which BIPV could be integrated, some technologies, like solar paint, are still years away before making it to the mass market.

  

  BIPV ceiling generates electricity while providing coverage

  Building integrated photovoltaics will continue to build interest and enthusiasm in the coming years as consumers look for ways to reduce energy costs as well as their carbon footprint.

  If you have moved to BIPV in recent years, please share your experiences in the comment section below.

  Mobile Solar Power to Save Money and Save Lives

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  

  Mobile solar power is a safe way to stay in touch using solar energy

  Mobile solar power – that is, portable devices that generate electricity with solar panels and other technology – can literally save lives.

  Whether we’re talking about solar powered refrigerators that can help keep medications cold for off-grid remote villages, or simply solar generators that can provide a clean boost for military operations, mobile solar options are here to stay.

  Portable solar power can be used by athletes or outdoors people to stay in touch when hiking, camping, fishing or even back-country skiing.  Using energy from the sun to power up cell phones, radios and flashlights is both safe and green.

  In addition to military solar operations, construction companies have also relied on solar generators instead of diesel to save fuel, money and cut down on greenhouse emissions.  Building contractors have saved precious time not having to re-fuel their generators, not to mention the potential of remediation costs when fuel is spilled.  Solar energy is clean, green and safe.  And it also operates silently – so no noisy generators running to bother neighbors or cause the need for a noise permit.

  Mobile solar power can also save lives.  As mentioned above, solar gadgets like the solar powered refrigerator use panels to generate electricity to keep perishable items cold in off-grid areas.  Even for people in developed countries, portable solar power could be the difference between life and death.

  In emergency situations like an earthquake, grid-based power could be knocked out for hours.  If you have devices that can be recharged with solar energy, you could reach the help you need when time is precious.   Or, consider the situation when you are backpacking or enjoying nature – a lost cell phone battery could be dangerous if you lose your way, as well.  Power up with solar panels instead and you’ll always be able to stay in touch.

  

  Solar generator used by the military is safer and less expensive than diesel options

  Lives can also be saved (or improved) using mobile solar power here in the U.S.A.  Large diesel generators used for making movies, construction industries and military operations emit massive amounts of CO2.  The exhaust also contains 40 cancer causing compounds, which can be avoided by the simple decision to switch to solar power.

  Mobile solar generators and other portable solar devices make sense from an economic and health standpoint.  Hopefully, we will all see the light when it comes to making sound energy decisions.

  Dow Powerhouse Solar Shingles

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  We’ve posted recently about solar roof tiles, also known as solar roof shingles, which blend right into your roofing materials, yet generate free solar electricity.  This year, Dow Powerhouse solar shingles will finally be available for consumers.  Financial experts predict that Dow Powerhouse Solar Shingles will reach revenues in excess of $5 billion dollars in the next four years.

  

  Dow Powerhouse Solar Shingles

  Solar shingles are a type of building integrated photovoltaics (BIPV), which blend right into rooftops because they look like asphalt shingles, yet they absorb solar energy to reduce a home’s energy requirements.  Dow Powerhouse solar shingles use copper indium gallium diselenide solar modules (CIGS) – innovative solar technology that is highly efficient.

  According to Jane Palmieri, managing director of Dow Solar Solutions:

  “The DOW™ POWERHOUSE™ Solar Single can be handled and nailed just like asphalt shingles. There’s no on-roof wiring, minimal through-roof penetrations and no need for an electrician to be present during the installation of the DOW™ POWERHOUSE™ Solar Shingle. A qualified builder or roofing contractor can do the install, and the electrical connections can be made later.”

  Because the solar roof shingles are so much like “regular” asphalt shingles, Dow Powerhouse solar shingles are compatible with both new and existing residential roofing.

  Dow Powerhouse solar shingles were was named one of the “50 Best Inventions of 2009″ by Time magazine.

  With generous tax incentives and rebates for solar energy, home solar power has been on the rise in recent years.  Dow Powerhouse solar shingles are both attractive and energy efficient.  Want to consider installing solar roofing materials on your home?  Read more about Dow’s product here.

  Solar Power Safer than Nuclear Energy

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  Every day – every hour, the problems with Japan’s nuclear reactors seem to get worse.  In the wake of the massive 9.0 Japan earthquake on March 11, 2010, radiation leaks from the power plants are causing major concerns.  Worldwide, countries are re-evaluating the safety of nuclear energy within their own borders.  Fears of what could happen in the wake of other major natural disasters leaves many giving solar energy a closer look.

  

  Solar power is proving to be safer than nuclear energy

  There can be no question that solar power is safer than nuclear energy.  Before the Japan earthquake, some commentators were starting to refer to nuclear as another form of clean, renewable energy.  That is fast changing, however.

  Since the disaster in Japan, some solar energy stocks have climbed 3-6% in just a few days.  Experts believe that the trend will continue to rise, causing more demand for solar power in the short term.  Moreover, the cost of solar is projected to be lower than nuclear power by 2015, even with safety concerns set aside.  As solar panel costs have been falling since 1998, the price tag for a new nuclear reactor has gone up from a projected $2 billion in 2000, to more than $10 billion today.

  

  Solar power vs. nuclear power

  Regardless of cost comparisons between the two energy sources, we can all agree that we’ll never have to evacuate thousands of people in the event of a “solar power meltdown.”  The only radiation associated with solar energy is pure sunlight.

  Perhaps its now time to give solar power its day in the sun, and reconsider our reliance on nuclear energy.

  How Much Can You Really Save with Solar Panels?

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  

  Save money with solar panels

  Solar panels can be a big investment, yet with prices having dropped 50% over the past few years and government incentives and rebates further slashing the cost, many homeowners are opting to go solar.

  With a solar power system, you can both save energy, cut annual electricity bills and even increase the value of your home.

  But not everyone is a believer.  Some still wonder how much can you really save with solar panels?

  Once seemingly reserved only for rich people, solar panels are not available for just about any person that has a roof over their head.  With residential power purchase agreements, solar lease programs, state and federal incentives, and property assessed clean energy programs, solar is both affordable, and can be financed to help defray upfront costs.

  Consider that solar leases and PACE programs (which allow you to finance renewable energy installations through an increase in your property taxes) can help you install solar panels with no money down.  That means that you can immediately start enjoying dramatically decreased – if not nonexistent – electricity bills right away.  Payments under solar leases are less than what you would be paying in monthly utility bills.  Likewise, the incremental property tax increase under a PACE loan will also be less than your electricity savings.  Further, you won’t suffer the impact of utility rate increases.

  

  Cut utility costs and save money with solar panels

  You can really save money and energy with solar panels.  Now that financing options are consumer-friendly, you can start reducing both your carbon footprint and your electricity bills immediately!

  Solar Powered Attic Fans Lower Temperatures and Energy Costs

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  Want to keep your attic cool and dry during the summer without hiking your utility bill?  Solar powered attic fans are becoming one of the most inexpensive, functional solar gadgets to hit the market.  Powered 100% without any electricity, solar fans can be easily installed and immediately save you 30% or more in your cooling costs.

  

  Solar powered attic fans help you save energy and keep your cool

  We all know that heat rises.  The trapped heat in your attic can make your air conditioning system work even harder to keep temperatures comfortable in your home.  But, with a solar powered attic fan, you can tap into the very sunlight that is heating things up, to help lower temperatures and energy costs.

  Here’s a video of how a solar attic fan works:

  There are a number of makes and models of solar fans from which you can choose.  Simply choose an area of your home that gets regular sunlight exposure for installation of the device.  A solar panel absorbs UV light, which is converted into power to operate the solar attic fan.

  You can find solar powered attic fans at many hardware and home improvement stores, as well as at Amazon.com.  Prices range between $250-500 for most devices.  Solar attic fans are also eligible for energy efficiency tax incentives and tax credits.

  Before the temperatures really heat up this summer, why not install a solar powered attic fan as a spring home improvement project?

  Solar Roof Tiles: Cover Your Electricity Bills

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  Did you ever stop and think about the roof over your head?  Not only does it protect you from the elements, but it could also help you save money!  With solar roof tiles, you can cover your electricity bills, as well as your belongings.

  

  Solar roof tiles can help cover your electricity bills

  Instead of bulky photovoltaic (PV) solar panels, solar shingles blend right in with your other roofing tiles.  They are embedded with silicon photovoltaic materials so they can absorb solar energy which is converted for use within your home.  Some homeowners have reported 60% savings on their energy bills with solar roofing tiles.  After all, solar electricity is 100% free and 100% clean.

  Solar roof tiles are a form of building integrated photovoltaics, which means solar energy producing building elements.  They blend right into the profile of your roof and actually last longer than regular roofing materials.  Once your solar roofing tiles are installed, you can simply forget about them and enjoy greatly diminished electricity bills.

  Solar roofing tiles are preferred by homeowners because they are not as heavy as solar panels and do not require roof penetrations.  They are less “ugly” and may be more readily approved by reviewing governmental agencies or homeowners associations that are concerned about aesthetic appearances.

  So, where can you find solar roof tiles?  Two manufacturers are leading the way in the U.S. for production and distribution of the product:  Dow Chemical Company and SRS Energy Co. Each of the solar tiles are attractive and functional.  Dow’s solar shingles are less expensive, but perhaps slightly less efficient than the SRS Energy Co.’s Sole Power Tiles.  With a professional installation, you can start drawing on free solar electricity to help cover your electricity bills soon!

  Put your roof to a good use beyond just providing you shelter.  Add some solar roof tiles and use some of the ample sunlight that falls on it each day.

  Solar Power to Reach Grid Parity with Fossil Fuels Within 5 Years

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  

  Solar power to be at grid parity in the next 5 years?

  Solar energy could power most, if not all of our electricity needs.  Yet, solar accounts for less than 1% of the U.S. energy usage, in large part because of its high cost.

  With recent advancements in solar technology, some analysts predict that solar power can reach grid parity with fossil fuels within 5 years.  That means that the cost to generate and transmit solar electricity from solar power plants would not be any more expensive than using coal or natural gas.  And – it goes without saying – that should encourage more regions to switch to solar power and give up the carbon-emitting energy sources!

  Clean tech research analyst Ahmar Zaman of Piper Jaffray & Co. notes that there are regions in the world in which solar power has already reached grid parity, including Hawaii and Italy.  In these places, it makes sense to look to ample solar resources where skies are often clear and electricity is expensive.

  But living in a less sunny area doesn’t mean that you can’t rely on solar power.  In fact, solar power plants installed in some of the Earth’s deserts could generate so much solar electricity that entire countries could be served with a solar power grid.  Many believe that we’re not too far away from such a scenario.

  In order for solar power to reach grid parity with fossil fuels, the price per watt has to come down a bit further.  Compare a 2007 solar power system, which cost about $8-11 per watt.  Today, that same system is only $4-5 per watt.  If you live in areas like Hawaii where the sun shines frequently and grid-based electricity is expensive, parity has already arrived between solar and fossil fuels.

  Now, just imagine the results if we imposed more taxes on coal-based electricity and natural gas!

  Street of Affordable Homes Relies on Solar Energy and Sustainable Building Practices

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  Here in my home state of Oregon, in the Pacific Northwest, solar power is kind of a big deal.  In fact, our state is a leader in solar energy in the U.S.  So, its not surprising that Oregon’s 2011 Street of Affordable Homes (in July this year) will showcase economies of scale that achieved from use of solar panels and sustainable building practices.  The event is co-sponsored by SolarWorld and LiveLight Energy.

  

  Affordable homes and solar panels are not mutually exclusive

  Information from the official website states:

  Announcing the 2011 SolarWorld/LiveLight Energy Street of Affordable Homes home show featuring six solar homes, built to Earth Advantage Silver specifications. All six homes are Energy Trust rated.

  • Featured homes will range in size from 2,500-3,250 square feet and will be priced between $410,000 and $450,000.
  • 4 builders, 6 homes at Stone Bridge Homes NW “Arlington Heights” community on Bull Mountain in Tigard

  So how can builders use the terms “affordable homes” and “solar panels” in the same sentence?

  Here’s how it works.  The solar panels are integrated into the overall cost of new construction, which allows homeowners to finance the solar panels along with their mortgage.  Any incremental increase in the mortgage bill is more than set off by savings on monthly electricity bills.

  To see these affordable homes with solar panels, the Street of Affordable Homes will run July 7-31, 2011 at Arlington Heights on Bull Mountain in Tigard, Oregon, which is just outside of Portland (and about 3 hours south of Seattle, Washington).  All homes include photovoltaic (PV) solar panels and are designed to meet requirements for energy efficiency, indoor air quality, environmental responsibility and resource efficiency. In addition to touring fully furnished new homes that won’t cost you a small fortune, SolarWorld and LiveLight Energy will give introductory solar demonstrations and showcase materials.

  Even if you are not in the market for a new home, you might get some ideas for home improvements to increase energy efficiency at your house.

  A new solar power plant in Los Angeles will power 85,000 homes. The City’s Department of Water and Power (LADWP) is joining forces with SolarWorld – a solar panel manufacturer – to build a 11.6 megawatt (MW) utility scale solar power station that will divert 290,000 tons of CO2 over the next quarter century.

  The partnership between the LADWP and SolarWorld will work as follows:  SolarWorld will supply the PV solar panels (more than 46,000 of them) and solar inverters for the Adelanto facility.  The district will construct and operate the station, selling the clean electricity generated by the solar panels to its customers in regions of Los Angeles.

  Solar Wind Marine Power System Moves Cargo Ships with Renewable Energy

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  

  Aquarius Solar Wind Marine Power System (image from Eco Marine Power)

  For hundreds – even thousands of years – humans have harnessed the energy of the wind to move ships across the seas.  But now this ancient idea is improved by tapping into solar energy, as well.  Eco Marine Power has developed technology it calls the Aquarius Solar Wind Marine Power System, which helps reduce the carbon emissions associated with moving huge cargo ships using solar energy and wind power to replace some of the fuel consumption.

  According to the company’s official website:

  The Eco Marine Power Aquarius System will allow ships to utilise wind power and solar energy in order to reduce fuel consumption and lower noxious gas emissions. In addition ship owners and operators will be able to reduce the C02 footprint of their fleet and employ the Aquarius Wind and Solar Power System on a variety of ships and vessels.

  The Aquarius System is being designed so that it will require little attention from the ships crew, will be relatively easy to install and offer an attractive ROI (Return on Investment) for shipping companies. The system will utlise solar modules and rigid sails connected to a central control and monitoring system. A prototype version of the system is planned to be ready by early 2012.

  In short, the tremendous amount of fuel and energy it takes to move massive cargo ships across the oceans can be minimized using wind and solar energy.  Lest ship operators be worried about maintenance and operation of the solar wind marine power system, it runs practically on its own with little to no work required by the ship’s crew.

  Although the first market for which the solar wind marine power system is aimed is cargo ships, Eco Marine Power has plans to use the same technology to move passenger ferries and other smaller vessels.

  Legislation Takes Aim at Ugly Solar Panels

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  For years, homeowners associations have restricted – or even banned – residential solar panels due to their aesthetic appearance.  Perceived as negatively impacting home values, some neighbors just don’t want to look at solar arrays.  Now, proposed legislation in Nevada would take aim at ugly solar panels, as well.

  

  Who gets to decide if solar panels are too ugly?

  Although Boulder City, Nevada has just approved the 5th solar power plant in the region, an Assembly committee hearing this week at the State Legislature heard concerns of residents that perceive the alternative energy equipment as an eye-sore and too reflective.  They’re also complaining about alleged noise impacts of wind turbines.  As a result, AB122, sponsored by Assemblyman Livermore from Carson City is proposed new solar legislation that would allow restrictions based on location and appearance (legally, cities and counties considering land use permit applications can add conditions to address height, noise or safety concerns).

  Not everyone is happy with the proposed new solar laws.  Concerns about the “chilling effect” that could result from the local adoption of rules relating to ugly solar panels and reflective wind turbines were raised by renewable energy advocates and other interested officials.  Regulating renewable energy apparatus based on appearance gives wide discretion for potential denial of land use applications, or the addition of conditions that may be impossible or too expensive to implement.

  And why overly restrict solar development in Nevada – a state that averages 300 sunny days a year!

  While some neighbors that testified expressed concern about ugly solar panels affecting property values, other groups proposed amendments to the bill such that it would only apply to large solar arrays, or be limited to setback restrictions, not location.  The bill has not been adopted yet, and further tweaks or amendments may be considered.

  What do you think about legislation directed at ugly solar panels?  A good idea or potential for abuse?

  Another Solar Power Plant Slated for Boulder City Nevada

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  Abundant sunshine, favorable governmental conditions and locations near high-voltage electrical transmission lines make Boulder City, Nevada the perfect place for solar energy.  In fact, the city council just approved the fifth solar power plant for the city, called the Black Hills site, in the El Dorado Valley Energy Zone.

  Boulder City Nevada is the site of several solar power power plants

  Utility scale solar power plants such as those approved in Boulder City (23 miles east of Las Vegas) require ample land, government approvals and proximity to transmission lines.  The solar power array to be sited on 1,500 acres of land will generate low-cost, clean solar electricity with photovoltaic (PV) panels.

  The newest solar power plant slated for Boulder City will join the 75 megawatt (MW) Concentrating Solar Power plant of Nevada Solar One, thin film solar installations of Copper Mountain III and El Dorado, and a planned 300 MW Posco Power/Sustainable Energy Partners PV solar installation planned to be completed by 2014.

  Is it any wonder that the region is called “Solar City”?

  

  A development agreement between Boulder City and Delaware-based Sempra Generation, secures the solar development for 50 years.  Its a win-win for both sides, with $200 million in payments flowing to the City from Sempra to help pay down existing municipal debt.

  Utility scale solar plants often rely on concentrating solar power (CSP) instead of traditional photovoltaic (PV) solar panels to generate clean electricity.  While CSP is considerably more efficient than PV power, its a land-intensive operation.  More than 5-10 acres for each megawatt generated is often required.

  But now Nanogen Power Systems, Inc. has developed concentrating solar power technology that uses shipping containers instead of vast swaths of land.  The solar development can be used for backup power in place of generators for just about any imaginable situation (military, government security, addressing civil unrest, etc.)  In short, they are freestanding, portable, off-grid solar power plants.

  

  CSP from a shipping container? (after)

  Here’s the quick facts about the new concentrating solar power technology:

  • Cost: between 12-18 cents per kilowatt hour (kWh), which gives coal a run for its money
  • Size: Where ordinary shipping containers (shown above) are about 20 feet long, if you combine three of them, you have the space required for a 1 megawatt CSP system
  • How does it fit?  Like other CSP power plants, the system includes parabolic trough collectors (the mirrors), a steam turbine and generator.  The turbine and generator go into a single 20-foot shipping container, and the collectors – that have fold-down walls – fit into the remaining two units.
  • Installation: No zoning or building permits are required for the transportable solar power system.  A pair of workers can fully assemble the CSP unit in two days with a laser level, compass and a few water pipe sections.

  Here’s how “ordinary” CSP technology works:

  Taking this impressive technology and shrinking it down into shipping containers for a wide variety of portable solar power demands is an impressive feat!

  Solar panels on capped landfills

  As a land use/environmental attorney, I’ve worked on so-called brownfields projects that redevelop environmentally-compromised properties, such as toxic waste sites or dumps.  Its the ultimate in recycling – re-using land that has already served its original purpose instead of spreading development outward from city centers.

  I was especially excited to hear about solar panel installations on capped landfills.  Unlike other brownfields projects, environmental concerns are diminished since human habitation does not need to be accommodated.  In fact, locally-elected officials are considering reclaimed landfills as a way to get green energy credits by allowing for installation of solar panels.

  As an example of this renewable energy brownfield development potential, 24,000 solar panels will be installed on top of a capped landfill in Canton, Massachusetts.  While most people wouldn’t want to seriously consider redevelopment of a site that used to be home to trash and refuse, the capped landfill can house a solar array to produce clean electricity for the residents of Canton.  In addition, the town will start collecting property taxes on the improved landfill.  With the combination of property taxes and energy savings for the municipality, officials predict revenue savings of about $70 million over the 25-year life of the solar panel project.

  Solar panels installed at the capped landfill will be finished by 2012.  The project will be developed by Boston based Southern Sky Renewable Energy.

  Other projects across the U.S. have already been developed with solar panels on capped landfills.  You can find similar installations in Colorado, California and Hawaii.  Turning an otherwise unusable site into a clean energy generating facility?  That’s not trash talk!

  Solar Parking Arrays in California to be Created by Envision Solar

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  

  Envision Solar uses "Solar Trees" for its solar parking arrays

  Using solar panels at parking garages and other parking facilities is a smart way to provide shade for cars and generate electricity for lighting and even electric car charging stations.

  Solar parking arrays in California will be created by Envision Solar International, Inc., pursuant to a contract with a major California utility.

  The project will use Envision Solar’s Solar Tree® structures.  Intended to raise public awareness of solar energy uses at parking facilities, the project will be highly visible, as well as open to the public.  The solar parking array will shade and recharge 36 electric cars, and will be completed by mid-2011.

  Solar panels used for the project will use EnvisionTrak™ multi-axis solar tracking technology.  Heliotropic action follows the sun as it crosses the sky, increasing efficiency of the solar panels by about 22%, as described in this New York Times article and this video:

  Robert Noble, founder and CEO of Envision Solar commented:

  “In addition to clean energy from the sun, the Solar Grove® will provide much-needed shade for cars and people and be an architecturally beautiful enhancement to the neighborhood. The local community will be able to charge their electric vehicles and plug-in hybrids and see renewable energy generation in their own backyard.”

  Envision Solar has paired its solar tree with batteries built by Axion of New Castle, Pa., so that the installation can deliver current after sunset, as well.  Because the solar parking arrays will be grid-connected, excess solar electricity will be fed back into the grid and, on cloudy days, electric car owners will still be able to recharge their vehicles.

  3M Ultra Barrier Film Covers Solar Panels To Reduce Weight and Cost

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  

  How 3M Ultra Barrier Solar Film Works

  You probably know 3M for its Post-Its or tape products, but now the company is working to change the solar landscape with the help of a $4.4 million grant for development of its lightweight Ultra Barrier Solar Film.  The grant, awarded through the Department of Energy’s SunShot Initiative, will allow 3M to expand production of Ultra Barrier Solar Film at its Columbia, MO plant.  The Ultra Barrier laminate is produced with the company’s flexible copper indium gallium selenide (CIGS) and other solar energy surfacing.  It shields photovoltaic (PV) cells, offering protection in place of glass.

  The lightweight material reduces the overall weight of solar panels, making them both lighter and more affordable.  By using Ultra Barrier on a conventionally-sized PV panel (4 x 6 feet), the panel’s weight would be only 1/8th of a typical 30-pound glass-covered solar panel.  This is important for rooftop solar installations on residences and commercial buildings where weight is a factor.

  Through SunShot, solar energy development will be accelerated, while solar panel installation costs can be dramatically reduced from $7 to $1 per watt of solar capacity.

  Solar powered coffee maker

  Do you enjoy camping, fishing or other outdoor activities?  How nice would it be to have a hot cup of coffee without firing up the camp stove?  With this solar powered coffee maker, you can use energy from the sun to brew your morning java.  Talk about a useful solar gadget!

  Students at the University of Calgary created the portable solar-powered coffee maker (shown above), which pumps water through vacuum-like tubes, heating it with solar energy.  No solar panels are required.  When sunlight hits the black wall of the inner surface, it heats up, warming the water.  It takes about an hour to brew 2 cups of coffee, so start it up before you cook breakfast or maybe even catch another few winks of sleep!

  The Two Hand Design student group from the University’s Faculty of Environmental Design came up with the invention through an industrial design course.  The solar coffee maker is called “Girasol” or sunflower in Spanish.

  You know that renewable energy is going mainstream when you can pick up a gallon of milk AND solar panels from the supermarket!  For people that live in the U.K., just head down to the local Sainsbury for a DIY solar panel kit.  The grocery store has partnered with British Gas to offer solar panels for sale right down the aisle from light bulbs and laundry detergent!

  Sainsbury’s stores are adding solar panels to their inventory as part of the new Sainsbury’s Energy program, which includes other ways to “go green” at home, such as insulation, gas and electricity deals, home energy assessments, and advice from”energy experts.”  Sainsbury CEO, Justin King, stated:

  “Our ambition is for Sainsbury’s Energy to become the number one destination for customers looking for new energy technologies, energy efficiency measures and great energy deals, so we can help them to reduce costs, while also reducing carbon emissions.”

  Solar parking canopy at California State University Bakersfield

  A new solar parking canopy at Cal State Bakersfield (CSUB) was activated this week on campus.  The 1.2 megawatt (MW) solar installation has been installed pursuant to a power purchase agreement between the University and SunEdison.

  The California State University did not have to spend any upfront costs.  Solar panels at the parking garage will generate clean electricity to offset the school’s grid-based demand.  In accordance with the agreement CSUB will purchase the electricity from SunEdison cheaper than utility rates and will be allowed to retain the renewable energy credits accorded to the solar parking canopy.

  The University’s website notes:

  CSUB has activated its 1.2 megawatt solar parking canopy in lots E and I. The 1.2 MW solar parking canopy will generate over 1.6 million kilowatt hours (kWh) of clean energy in the first year of operation and produce over 30 million kWh over 20 years. That is enough energy to power more than 3,100 average U.S. homes for one year.

  Wse of the solar parking canopy will offset more than 29 million pounds of carbon dioxide over the initial 20 years of operation, which is the equivalent of taking 2,800 cars off the road.  The solar panels will generate 25-30% of the electricity required for the school’s total energy use.

  SunEdison has now completed 8 solar power projects for various California State University schools, with an overall 4.3 MW of capacity.

  Solar Panels Generate Power to Remove Ice and Snow from Bridges

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  

  Ice and snow on the roadways could slow you down

  While Punxsutawny Phil might be predicting an early spring in 2011, the reality is that many regions of the U.S. will continue to see snow and ice well into March and possibly even April.  For commuters and other drivers, one of the most dangerous places to encounter winter accumulations is on elevated roadways.  So, how do you get to your destination safely?

  Designer Corey McDonald of Pave Guard Technologies invented a system that uses solar panels to generate power to remove ice and snow from bridges and overpasses.  He discusses the solar technology in this video:

  Not only is the use of solar panels effective, but its also “green.”  Most ice and snow melt systems require salt, cinders or other harmful applications on road surfaces.  The chemicals and debris clog water systems and dirty the streets.  They are also expensive and wasteful, often ending up in landfills.

  Using solar panels to generate power to remove ice and snow ends up saving both the environment and taxpayer money.  As described on the Pave Guard Technologies website:

  • Solar energy is generated and routed through a closed end piping system.
  • The Pave Guard System can generate high voltage energy as a stand alone system as well as being tied into the electric grid for added support.
  • A glycol water mixture is piped through the in-ground system warms the pavement, preventing the formation of snow or ice on the pavement.
  • Pavement does not freeze, which means no black ice, and fewer potholes that are expensive to fill and cause substantial damage to vehicles
  • When weather improves in warmer months, the solar energy that is generated is fed back into the power grid.

  Here in my neck of the woods, we’ve seen snow into June on occasion!  I think using solar panels to help keep bridges and overpasses clear and safe is a super idea.

  New Solar Thermal Rebate Program in Massachusetts

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  One of the “easiest” ways to go solar without the big upfront expense is to install a solar hot water system.  Solar thermal panels, like the ones shown below, are relatively inexpensive and provide “free” hot water after installation.  No more energy required to heat water for showering, washing clothes and dishes.

  A new solar thermal rebate program in Massachusetts will lower the cost of this renewable energy system even more.

  

  Solar Thermal Panels Heat Water for Free

  The solar rebate program will be administered by the Massachusetts Clean Energy Center and will result in about $1,000 back on a 2-panel solar hot water system. The typical cost of a solar thermal panel system is $8,000-$10,000 for a single-family household.  In addition to the Massachusetts rebate, property owners can tap into state and federal incentives, including the 30% federal renewable energy tax credit.

  But what, exactly, is a solar thermal (hot water) system?  Watch this video to learn more:

  Will you be eligible for the new solar thermal rebate program in Massachusetts?  If you reside in the state, you must be a customer of NSTAR, National Grid, Unitil, or Western Massachusetts Electric Company.  If you’re not, then you must reside in Ashburnham, Templeton, Holden, Holyoke or Russell, MA.

  The solar rebate program is funded by the MassCEC’s Renewable Energy Trust.

  Solar power in Nevada

  All across the “Land of Enchantment” the state of Nevada is shining bright with a solar power future.  To the south, near Boulder City, over a million solar panels cover desert lands, generating utility scale solar electricity. Using First Solar panels, the project will generate enough clean electricity to power about 26,000 homes, saving 123,000 metric tons of CO2 with the positive environmental impact of taking 24,000 cars off the road.

  Up north in the Truckee Meadows, smaller solar panel arrays are also sprouting up.  While on a scale smaller than the First Solar farm in the southern part of the state, distributed generation photovoltaic (PV) panels generate electricity for the property on which they are situated.

  For example, NV Energy uses solar energy to keep the lights on at their Reno headquarters.  Not only is the company using solar power, it is adopting incentives to help residential and small business customers make the switch to the renewable resource, as well.  A new solar hot water incentive allows between $3,000 and $7,500 to off-set initial costs of the system.

  How the Federal Solar Tax Credit Works

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  You have probably heard that the federal solar tax credit can reduce your out-of-pocket expenses if you are considering installing solar panels on your home or business.  But just how does the solar credit work?  How much money can you really save?

  

  How much can you save with the Federal Solar Tax Credit?

  In general, the investment tax credit allows up to 30% of the cost of a solar photovoltaic (PV) system and its installation.  The fact that it is a tax credit, rather than a rebate, means that you need to have a tax bill against which to offset the credit.  The federal solar tax credit currently may be carried over for five years until 2016.   So, if you owe less in taxes for 2010 than the value of your solar tax credit, you can carry over the remainder to apply to the next 4 years of tax bills.

  If you have installed solar panels on your home (your primary residence) or are planning to do so this year, consider this information:

  A typical residential solar PV array is 5 kilowatts (kW), with is estimated to  cost $41,000 ($8.20 per watt), including installation.  Thirty percent of that cost, which would be the federal tax credit, is $12,300.  If your family earns $60,000 a year, the estimated federal income tax is about $2,500, which means the federal tax credit could essentially reduce your tax burden to $0 over the next 5 years.  Those who earn less may not be able to claim the entire credit if they do not have a large enough tax bill against which to offset the credit.

  If solar PV panels continue to drop in cost, the number of people who will be able to capture the full credit for a given system size will increase. Yet, some commentators believe that new incentive schemes should be adopted so that returns on solar investment are not dependent on the tax code.  Tying the rebates to renewable energy generation may provide better renewable energy incentives.

  Rooftop Solar Incentive Fund in California Running Out

  Million Solar Roof Program in California

  If you live in some areas of California and have thought about installing solar panels on your rooftop, you’ll want to hear this recent announcement.

  Due to extreme demand and the overwhelming success of Governor Arnold Schwarzenegger’s Million Solar Roofs initiative (which started in 2006), the state has run out of money to hand out in one of its solar rebate programs.  According to the DSIRE, a database of solar incentives (at the state and federal level), the Rooftop Solar Incentive Fund in California has been exhausted.

  The California Solar Initiative no longer can offer rebates to business and industrial customers in territories served by Pacific Gas & Electric’s (PG&E’s) and San Diego Gas & Electric.  Southern California Edison’s business customers may still tap into the program, however.  Tiered rebates, which descend in value depending on the size of the solar array, kilowatts installed, and for each year it has been in service, may be claimed.

  Is this all bad news?  Not necessarily because the fact that the rooftop solar incentive fund in California has nearly run out shows the tremendous success of the program.  However, it has been ended 5 years before its original expiration date of 2016.  For those that are worried about the potential impact of the loss of the state incentives for business-related solar electricity panels and solar hot water systems, rest assured that legislators in California are still renewable-energy leaning.

  If the rebates are extended, the California Solar Incentive program may find new life, nce again!

  The largest solar PV system on an assisted living facility in the United States has been completed at San Clemente Villas by the Sea.  Solar Electrical Systems of Westlake Village, California completed the 288 kilowatt (kW) solar electric systems – three of them – for the property.

  

  Solar powered assisted living facility

  Not only will you find rooftop solar panels at San Clemente Villas, but also a solar carport and ground-mounted solar panels on a nearby hillside.  The assisted living facility selected Solar Electrical Systems to complete the project given its long-term reputation for solar installations in the area.

  The most challenging part of the solar PV system was installing the ground-mounted panels on the hillside.  The steep terrain lacks freeway access, yet Solar Electrical Systems was able to transform otherwise unusable property into system that generates clean electricity for the assisted living facility.  Not only that, but its proximity to Interstate-5, a major thoroughfare, demonstrates the power of solar energy to commuters on a daily basis.

  San Clemente Villas projects that it will save money almost immediately by going solar.  Solar rebates and tax incentives defray 87% of the costs for the solar PV system.  The solar panels will pay for themselves within 4 years, given the amount of free solar electricity generated by the system.  Over the 30-year life of the project, the assisted living facility will save more than $16 million in power bills.

  Cimarron Solar Facility in New Mexico

  The 30 megawatt Cimarron Solar Facility recently started commercial operations and is one of the largest utility scale solar power plant in the U.S.  While New Mexico is not usually thought of as warm, it does have plentiful sunshine!  The new solar PV plant generates electricity for about 9,000 homes.

  The solar facility was developed by First Solar, which will operate and maintain the plant during the life of a contract.  A partnership between Southern Company and Turner Renewable Energy owns Cimarron Solar Facility (purchased from First Solar) and will supply power to Tri-State Generation and Transmission Association (a not-for-profit wholesale power supplier to 44 electric cooperatives across Colorado, Nebraska, New Mexico and Wyoming) pursuant to a power purchase agreement.  It was actually finished ahead of schedule and started producing solar electricity in December 2010.

  The 364-acre plant site includes 500,000 2′x 4′ advanced thin film photovoltaic modules manufactured by First Solar.  The utility scale solar power plant is adjacent to Turner’s Vermejo Park Ranch, within the service territory of Tri-State member system Springer Electric Cooperative in Colfax County, N.M.

  Cut Solar Installation Costs by Streamlining the Permit Process

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  When it comes to solar installation costs, there are people that believe the easiest place we can save money is in the permit process.   Not only does it cost money to apply for land use approval, but it takes a great deal of time.  If your home is subject to additional land use regulations relating to historic preservation or if you also need a signoff from your homeowners association, plan on at least 12 months from start-to-finish.  In these situations, homeowners often hire attorneys to help guide them and avoid potential pitfalls that could result in denial of the solar project, which costs even more!

  

  Home solar panel costs can be cut with a streamlined permit process

  Each year, $1 billion (with a “B”) is spent to jump through the permitting and inspection hoops in the United States.  By trimming these costs, one report expects a saving of $2,500 per residential solar installation.

  Think about that – instead of a $12,500 solar panel system, you could have the same one for $10,000!

  Ever wonder why there are so many solar panels in Germany?  In that country, installation costs are about 40% lower than in the U.S. because of a streamlined permit and inspection process.  Compare the 1 million homes with solar panels in Germany with only 120,000 in the United States.  The president and CEO of the Solar Energy Industries Association (SEIA) observed:

  “Local permitting red tape keeps solar off of millions of American homes and businesses.  Policymakers need to recognize that these additional costs put an undue burden on new, clean technologies like solar that are trying to create jobs in the U.S.”

  While the U.S. Department of Energy (DOE) has been requested to help local governments streamline the permitting process for solar panels, I’m not holding my breath that it will happen.  I’ve been practicing land use law since 1994 and can say – quite simply – that once land use regulations are in place, you really cannot turn back time and remove them entirely from the books.

  We could mandate decisions to be made within 6 months of application, but that does not prevent people opposed to your solar panels from appealing the decision.  We can amend existing regulations to effectively de-regulate solar panel installations, but in this country, due process cannot be legislated away.  That means everyone gets a say about how land is developed and improved.  In this country, we’d rather err on the side of too much process than too little.

  Does this mean we should not try to streamline the permit process – not at all!  I am a big fan of cutting red tape.  I support the efforts of the DOE and any local government that works to encourage solar installations with incentives and quick review processes.

  Solar Panels Denied Under Historic Building Preservation Regulations

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  

  Its difficult to get approval to put solar panels on historic homes

  As a land use lawyer for the past 20 years, I understand the need for regulations to protect certain uses from incompatible construction or improvements.  Oftentimes, there is a delicate balancing act between protecting private property rights of the applicant and enforcing land use restrictions that are intended to benefit the public as a whole.

  Recently, this clash manifested in New Orleans, LA, when solar panels were denied under historic building preservation regulations.  City officials through the Vieux Carre Commission determined that rooftop solar panels which require roof penetration and – let’s face it – can be a visual eye sore were not consistent with maintaining the historical integrity of the 1834 French Quarter home on which they were proposed.

  Historic building preservation regulations are not unique to Louisiana.  Across the country, historic preservation offices are frequently called to determine whether additions like solar panels are consistent with traditional aesthetics of structures.  The National Trust for Historic Preservation in Washington notes that more and more often, local building officials and historic preservation departments are called on to balance homeowners’ desires to go green against maintaining the integrity of the original structure.

  

  Solar panels consistent with historic buildings?

  With images like the one to the right in mind, reviewing agencies seek to prevent the jarring appearance of solar panels from detracting from the aesthetics of historic buildings.  And its not just historic building preservation regulations that are coming into play.  Homeowners Associations (commonly known as “HOAs”) often reserve authority to review, approve or deny additions to homes in certain neighborhoods.  Solar panels may be viewed as ugly or even a negative impact on property values, despite the fact that a home with solar panels is worth more than one without.

  So what is one to do?  Historic building preservation is a more difficult issue than getting approval from an HOA.  Neighborhood rules can be revised and the boards of directors can be educated regarding the value of solar panels on a home.  But when it comes to maintaining the structural integrity of a historic building so that it looks like it did when constructed, bulky solar panels probably won’t make the grade.  Even if they are proposed for the rear of the home, due to concerns of setting a precedent for additional applications for approval of solar panels.

  Your best bet is to go with solar roof shingles, which are a type of building integrated photovoltaics.  The solar tiles made with thin film solar cells, blend right into the profile of the roof and penetrations are not required to secure them to the rooftop.  Alternatively, if allowed under local land use regulations, constructing a stand-alone shed or garage (that would not be a historic structure) on which solar panels could be installed might be an option to consider.

  But here’s the other side of the coin.  A new study says that we could be 100% renewable energy reliant by 2030.  Two U.S. researchers, Mark Delucchi and Mark Jacobson, believe that we could tap into ample natural resources to such an extent to completely power all homes, businesses and factories world-wide in less than 20 years.

  The results of the study were published in a recent National Geographic article entitled, “Going ‘All the Way’ With Renewable Energy?”

  So, just how can this leap occur?  How is it possible that we can somehow pull a 360 degree turn from using coal, natural gas and oil as more than 80% of all energy, to going 100% renewable energy reliant?

  The authors of the new study note that many new energy generating systems would have to be built.  More precisely:  4 million 5-MW wind turbines, 90,000 300-MW large-scale solar plants, and 1.7 billion rooftop PV systems at 3 kW each.  Notably, the study excludes biomass and carbon-free electricity generation, as those power plants rely on fossil fuels.

  There are several variables that will affect whether and how we could ever truly become 100% renewable energy reliant.  First, we’ll need vast stretches of land on which to build wind turbines and install solar power plants.  That, of course, is a political hot potato.  Second, we’ll need to quintuple production of rare earth minerals like neodymium, which is used to make magnets.  Third, we’ll need significantly more political support and governmental incentives to back up a build-out of this magnitude.

  Its staggering, really, when you consider the potential impacts of such a proposal.  From the National Geographic article:

  Delucchi and Jacobson estimate that a drive for 100 percent renewable energy would require a massive building binge. For instance, the world would need nearly 4 million wind turbines, and they’d be big ones—rated at 5 megawatts (MW). That’s two or three times the capacity of the majority of turbines on the market; 5 MW turbines were an innovation introduced offshore in Germany in 2006, and China just built its first 5 MW wind turbine last year.

  The pair estimate that the world would need 90,000 large-scale solar plants, each with a capacity of about 300 MW—both those that rely on photovoltaic panels that make electricity directly, and concentrated solar power plants that focus the sun’s rays to boil water to drive electric generators. At present, fewer than three dozen such utility-scale solar plants are in operation worldwide; most are far smaller.

  And the big solar systems wouldn’t displace the need for rooftop power; the researchers estimate a need for 1.7 billion 3-kilowatt solar PV systems as well. Think of that as one rooftop PV system for every four people on the planet.

  Building all these new turbines, solar panels, and other infrastructure would eat up plenty of steel, concrete, and other resources. However, Jacobson and Delucchi concluded there are no significant economic or environmental constraints on the production of bulk materials such as concrete and steel, so they examined more closely the needs for less common materials.

  Whether or not we really will become 100% renewable energy reliant by 2030 is probably beside the point, however.  The authors of the study published it (apparently) merely to show that the potential to do so is there – not to suggest any ways to clear the significant practical and political hurdles that stand in the way.

  Solar Panel Maker Moves to China from United States

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  

  Evergreen Solar moves U.S. production of solar panels to China

  Since the recession began in 2007, the United States government has purported to try to stimulate the economy and create new jobs.  Green jobs have been one of the Administration’s focuses, but apparently not enough so.

  Last week, Evergreen Solar – the third largest maker of solar panels in the United States – announced that it was closing its main factory here and moving production to China.  The stated reason?  Higher government support there.

  Evergreen Solar is entering a joint venture with a Chinese company and laying off about 800 American workers in Devens, Massachusetts by the end of March 2011.  Not surprisingly, the move of the solar panel maker to China has resulted in a political outcry.  Here in the U.S., people are wondering how many more green solar jobs will be lost to China.  And the Obama Administration is investigating whether China has violated free trade rules of the WTO by offering extensive subsidies to manufacturers of solar panels.

  Evergreen’s CEO Michael El-Hillow commented that the decision to close the U.S. manufacturing plant was in response to dropping prices for solar panels, down about 2/3 over the past three years.  Chinese manufacturers of solar panels have been able to push prices down because costs to build them are generally lower in China:

  “While the United States and other Western industrial economies are beneficiaries of rapidly declining installation costs of solar energy, we expect the United States will continue to be at a disadvantage from a manufacturing standpoint.”

  

  Cheap solar panels produced in China

  Consider these facts:

  • Chinese solar panel manufacturers made up over 1/2 of the world’s production of PV
  • U.S. consumers are purchasing China solar panels at an increasing rate – they make up 23% of the market currently and still rising
  • China is also making gains in the wind energy markets, surpassing the U.S. as the world’s largest manufacturer and installer of turbines
  • Factory labor in China is especially cheap – workers draw about $300 a month, vs. $5,400 a month for U.S.-based workers
  • Government loans in China offer exceptionally low interest rates from state-owned banks

  So, what can be done to keep green solar jobs in the U.S.?  More federal support?  Better incentives?

  Can we compete with the clean energy policies of China that offer such attractive financing and other assistance to solar panel manufacturers?

  Solar-Powered Electric Cars

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  

  Will you drive a solar powered car some day?

  Experts are predicting that 2011 is going to be the year of the electric car.  Several auto manufacturers are releasing new 100% electric or plug-in electric hybrid models this year.  Many new concept cars will soon be driving major highways in the next few years, as well.

  All this means that solar-powered electric cars are on the horizon.

  Currently, several green cars offer solar panel options for consumers.  The Toyota Prius (not an electric car yet) is a traditional hybrid that can be outfitted with PV cells on its roof to offset battery drain running the air conditioning.  It can help boost mileage too!  The new 100% electric Nissan LEAF also has a solar panel option, which 70% of its buyers are choosing.  Like the Prius, the solar panels will help power internal operations of the automobile, though will not actually recharge the battery.

  But, solar powered cars that run on 100% renewable solar energy are still in the future:

  The primary reasons we do not yet see cars that are covered in solar panels driving around is that too many panels would be required to completely power the vehicle, and the cost would be prohibitive for most consumers.

  A solar electric car has been developed.  The experimental Swiss “Solartaxi,” was developed to circle the globe and powered entirely by energy generated by solar panels.  However, the vehicle required a solar array on a trailer that was nearly as big as the Solartaxi itself!

  For now, if you want a solar-powered electric car, your best bet is to purchase an electric car.  Then, instead of plugging it into the grid, install solar panels on your garage, or recharge at one of a solar park and ride facilities or solar powered garages like the ones shown below.

  The Politics of Solar Power

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  

  Blue PV solar panels have some people seeing red

  Anyone that has been following the news over the past few years in Southern California will see that the politics of solar power is not easily navigated.  When it comes to utility scale solar power plants, the idea of green, renewable power isn’t the end of the story.  For many environmentalists, developing what would otherwise appear to be bare, scrubby desert land with shiny, reflective PV panels or thermal solar power plants including parabolic mirrors and a ton of water for steam is just as bad as slapping up a WalMart mega-store.

  Fragile habitat for various species that inhabit the Mojave Desert and other desert southwest areas where the sun shines brightly, just begging to be utilized for solar energy, has called in groups like the Sierra Club to litigate against proposals for solar energy development.  Sure, solar power can bring green jobs and reduce our carbon emissions.  But when the politics of solar power come into play, the result can be abandonment of U.S. development to countries like China, where environmental opposition is less likely to occur.

  As the U.S. and the world struggle to address issues related to global climate change and finding new, reliable sources of energy, many are finding it ironic that environmentalists are the ones often opposing clean power like solar and wind.  I’ve been a land use attorney since 1994 and my view is that some of these groups and individuals simply oppose development of any kind or nature, no matter its overall purpose or goal.  Yet, the land use development systems in the United States (at the federal, state and local levels) allow for citizen input, detailed environmental review and a siting process intended to insure that proposed development is appropriate in scale and for its location.

  All development will have some impact.  You simply cannot site any construction without change.  The question becomes one of balance, mitigation of impacts and a long-term vs. short-term consideration.  Let the debates continue.  The politics of solar power have an appropriate place and open discussion is the hallmark of any political process in this country.  But, hopefully, we can all agree that coal plants need to be replaced with utility scale solar (and wind, hydro and even nuclear).

  Solar panels on your carport or garage can charge your 100% electric Nissan LEAF

  Perhaps its just the type of “green” owners that are buying (or considering) the new 2011 Nissan LEAF, but an informal poll at a forum at MyNissanLeaf indicates that Nissan LEAF electric car owners want solar power charging for their vehicles.

  The poll includes four choices:  solar, green utility-based power, “regular” utility-based power and “other.”  The poll is still in its infancy, but of the 112 respondents (so far), 50% indicated that they would like to charge the battery-powered Nissan LEAF with solar energy.

  Fortunately, there are several options to tap into solar power for the Nissan LEAF and other electric vehicles.  Homeowners can install solar panels on their home or even go with a solar carport (pictured above).  In some areas in California, you can find solar-powered parking lots that include outlets for plugging in EVs for recharging.  There are even solar park and ride facilities.

  With the price of oil already climbing in early 2011, experts are predicting $5/gallon gas by this autumn.  Perhaps its time to think about an alternative fuel vehicle like the Nissan Leaf?  With solar power charging, you can reduce carbon emissions of your commute practically to zero.

  Solar Electricity in Nature: Oriental Hornet Generates Power from Sunlight

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  

  Solar Power Generating Hornet

  Solar energy, in its pure, direct form of sunlight is 100% natural.  We know that of course.  But to convert the energy into usable electricity, mankind has developed solar cells using materials like silicon.

  Surprisingly there is solar electricity in nature.  The oriental hornet, pictured to the right, has the ability to generate power from sunlight.  According to a recent National Geographic article, the insect literally has cells within its exoskeleton that can produce electricity when exposed to sunlight.   Its the first solar power generating animal known to man.

  A scientific study, led by Marian Plotkin of Tel-Aviv University unveiled the process by which the oriental hornet generates power from sunlight.

  Their research revealed that pigments in the hornet’s yellow tissues trap light, while its brown tissues generate electricity. Exactly how the hornets use this electricity is still not entirely understood, Plotkin noted.

  The researchers also discovered that while man-made solar cells have an efficiency rate of about 10-11%, the hornet’s “solar cells” are only about 1/3 of 1% efficient.  In other words, the hornet still needs to eat food for energy!

  Yet, scientists are excited about the discovery because its the first of its kind for the animal kingdom.

  The National Geographic article explained:

  The team found that many of the hornet’s brown tissues contain melanin, the pigment that protects human skin cells by absorbing damaging ultraviolet light and transforming it into heat.

  A structural analysis of the brown tissues also uncovered grooves that capture light by channeling rays into the tissues and breaking them apart into smaller rays.

  The brown tissues “are a lot like a light trap—only one percent of the light that strikes is reflected away,” said Plotkin, whose study appeared in the December issue of the journal Naturwissenschaften.

  The hornet’s yellow tissues contained the obscure pigment xanthopterin, which gives butterfly wings and mammal urine their color.

  What does this discovery mean for solar research and the development of future solar technology?  The research team used isolated xanthopterin in a solution which was placed inside a solar cell electrode conductor.  When sunlight hit the electrode, the pigment generated electricity.

  The research is just the beginning.  Scientists will compare the exoskeleton of the oriental hornet to other insects to see if there are others that are also generating power from sunlight.

  Just possibly, we’ll be seeing solar energy taking flight in the natural world!

  What are Solar Panel Kits?

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  

  Sunforce Solar Panel Kit

  If you are in the market for residential solar power, you might have heard about solar panel kits.  The name itself makes it sound like an easy DIY home improvement project.  And for some, going with a solar panel kit is easier than contracting with a solar power company to purchase individual components of a system and have them installed.

  You’ll want to know what is and isn’t included in a solar panel kit, however.

  What are Solar Panel Kits?

  In general, solar panel kits allow you to go “solar out of the box.”  The kits generally come with photovoltaic (PV) solar panels, an inverter, and charge controllers.  Some assembly required.

  There are a range of solar panel kits on the market at different price points.  Generally, the more expensive solar kits include a greater number of solar panels and better quality inverters and charge controllers.  For example, this solar panel kit from Home Depot has 10 Sunforce 123 Watt panels and a Pro Series inverter with a continuous output of 2500 Watts, and a surge power of 5000 Watts.  It will cost you nearly $9000, prior to federal and state incentives and rebates.

  Amazon.com sells a much less expensive ($479) solar panel kit which is best suited for recreational vehicles (RVs), boats or swimming pools.

  Advantages of Solar Panel Kits

  There are several advantages to going with a solar panel kit.  Generally speaking, they are less expensive because you are not paying for installation services.  Many people say that solar panel kits are more convenient and easier to modify to meet their own home energy needs.  For handymen and women, I’d agree that DIY solar panel systems can save you both money and headaches.

  Disadvantages of Solar Panel Kits

  Many homeowners prefer to contract for the purchase and installation of solar panels instead.  Professional installation is often more reliable and comes with a warranty – perhaps worth the additional cost.  In addition, some solar power companies will assist you with paperwork to maximize your solar rebates and other incentives.  That in itself can be a huge headache!  Obviously, solar panel kits do not come with any professional services.

  Should you go with a Solar Panel Kit?

  Only you can decide what makes sense for your household.  For smaller solar power systems such as those used with RVs, boats and worksheds, a solar panel kit could be perfect and more economical.  Larger systems such as those to power an entire home or small business may do best with a professional installation.

  Have you recently gone solar?  Please share your own thoughts and opinions below regarding solar panel kits vs. professional installation.

  The Hydroleaf: Using Solar Panels to Provide Shelter and Purified Water

  Solar panels provide shade and purify drinking water with the Hydroleaf (image by Mostafa Bonakdar)

  The Hydroleaf is a cool solar invention developed by Mostafa Bonaka which uses solar panels to provide shelter and purified water.  Perfect for regions like his native Iran, Bonaka developed the Hydroleaf as a transit-style shelter that uses solar panels to provide shade, as well as generate electricity to power safety lighting at night and to purify water collected by the invention.

  The concept design works as follows:  a solar panel “leaf” is covered with photovoltaic cells to generate solar electricity, as well as providing shelter from the sun.  The leaf also collects rainwater, which is channeled into a 60-gallon reservoir where it is purified using power generated by the solar panel.  Pedestrians passing by can enjoy cool, fresh water from a water fountain on the side of the Hydroleaf.

  

  Another view of the solar powered Hydroleaf (image by Mostafa Bonakdar)

  In hot, arid regions, the Hydroleaf would be the perfect addition to the street scape.  Shade and shelter from the hot sun is always welcome, of course.  But solar powered water purification is what sets this solar invention apart.  Clean drinking water to provide hydration, without the use of those ubiquitous plastic water bottles that end up in our landfills and oceans, is always needed in all areas of the world.

  We’d love to see the Hydroleaf move from concept design to street corners soon!

  Science meets art with a new machine created by Michael Jones McKean, a professor at the Virginia Commonwealth University, that generates artificial rainbows using solar power and harvested rainwater.  McKean plans to install a public art project showcasing the solar powered artificial rainbows at the Bemis Center for Contemporary Arts in Omaha, Nebraska next June.

  According to his website, McKean creates rainbows using sunlight and water sprayed into the air by a series of pumps, hoses and nozzles.  The water used for the public art project is recaptured rainwater, and it is continuously re-circulated by way of the building’s water/gutter system.  Solar power factors into the project by way of photovoltaic (PV) solar panels that generate clean electricity to power the water pumps.

  When McKean sets up the artificial rainbow project at the Bemis Center in June, rainwater will be collected from the roof and funneled down a custom system that will recapture the water for further use after it is sprayed into the air to create the rainbows.  A solar power system will be used to power the pump and spray mechanics, as well.

  Residents of and visitors to Omaha, Nebraska will enjoy the artificial rainbow displays twice a day for about 20 minutes from distances as far as 1000 feet away.  You’ll even be able to walk through the display, marveling at the unique quality of each rainbow created.

  Solar panels to power cruise ships in California Ports

  It probably shouldn’t come as a big surprise, but the giant cruise ships that are so popular among travelers these days have an even bigger carbon footprint.  In fact, the environmental impact of enjoying a cruise is more than three times larger than that of flying on a Boeing 747 (comparing 24 hour periods for each type of travel).

  Two ports in Southern California now help cut the greenhouse gas emissions of cruise liners and shipping vessels- at least while they are in port!  Taking the lead from the Port of San Diego, the Port of Los Angeles now includes solar panels to power cruise ships that are docked.  A 1-megawatt (MW) solar panel system in Los Angeles will generate 1.2 million kilowatt-hours (kWh) of clean solar electricity that can be used in place of the diesel generators typically run on ships while berthed.

  The solar panel installation is but one part of an overall plan for the Port of Los Angeles to go green and reduce its environmental and negative health impacts:

  The Port of Los Angeles estimates budget savings of $200,000 per year in energy costs as a result of the solar panel installation.  And, it is just the first step in an overall plan to increase the size of the solar panel system from 1 MW to 10 MW!

  Cutting down on diesel emissions and switching to clean, renewable solar power for port-side electricity will help both the people of Los Angeles and the globe breathe a little easier!

  Solar Scorecard Assesses Manufacturing of Solar Panels

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  

  Solar Scorecard can tell you how many toxins are in your solar panels

  Among several of the so-called “strikes” against solar panels is the alleged environmental impact of manufacturing them.  Now, you can be a wise consumer, by checking the Solar Scorecard.  This website assesses manufacturing of solar panels and compares manufacturing processes to help you determine which solar panels are the most eco-friendly.

  The Solar Scorecard is a project of the Silicon Valley Toxics Coalition.  It uses data reported by solar panel manufacturers (both PV and solar cells) regarding energy required to produce the products, and use of materials like lead and cadmium.  In short, its a snapshot of those companies that are taking steps to limit potential harmful impact of their products.

  According to the website, the 2010 Solar Scorecard is just the beginning:

  “We plan to update the scorecard annually to reflect the dynamic nature of the industry. The scorecard serves as a resource for institutional purchasers, investors, and consumers- anyone who wants to be sure that the solar PV panels they purchase are produced by companies that are responsible stewards throughout product lifecycles. The survey also enables companies to see where they rank relative to their competitors and where they need improvement.

  We greatly appreciate the efforts of the companies that chose to respond fully to the survey. We see this as a first step in working together to share information, to improve practices, and to protect communities, workers, and the environment. This collaboration will help build a firm foundation for the long-term growth of the sector.”

  Currently, there are only a total of 11 solar manufacturers listed on the Solar Scorecard, because the data is based on self-reporting.  Four of the listed companies have a gold star, which indicates that they have implemented recycling/takeback programs to limit end-of-life contamination issues (noted above).

  The Solar Scorecard should be updated in 2011.  The current information on the website is based on a survey sent to 27 solar manufacturing companies in October 2009, with data compiled in January 2010.  The hope is that more respondents will participate in the Solar Scorecard so that consumers, other manufacturing companies, government agencies and even employees of the solar manufacturers can compare and contrast use of toxic materials and end of life recycling.

  Tags:    [edit]

  A solar powered refrigerator invented by a British Student is bringing hope to village residents in Namibia, Africa.

  Young Emily Cummins came up with a refrigeration unit that runs on the power of the sun, without the need for expensive solar panels or complex technology.  Cummins’ solar powered refrigerator is a relatively simple design.  Shown to the left, the invention requires two cylinders, a metal one inside the outer cylinder created of plastic or wood.  In the air space between the cylinders, either wet soil or wet sand is placed.  When radiant heat from the sun warms the material, water evaporates, drawing heat from the inner cylinder.

  The interior of the solar powered refrigerator can stay cool at only 6 degrees Celsius.  Emily’s invention is changing lives for the villagers that live off-grid.  Now, they can enjoy fresh, safe milk and meat that can be stored inside the refrigeration unit.  The lack of electricity should not mean that perishable goods cannot be safely kept for future use.

  Cummings is a graduate of Leeds University, and hopes the change the world with her inventions like the solar powered refrigerator!

  Solar Energy To Light Up Egyptian Villages

  Utility scale solar power for Egyptian villages

  It only makes sense that remote villages – difficult to reach and off-grid – should rely on renewable resources like solar power to provide light, heat and other modern conveniences.  For the first time ever, solar energy will light up two Egyptian villages.

  The Egyptian government has adopted solar energy initiatives to encourage more solar energy usage.  The Egyptian villages of Umm al-Saghir and Ain Zahra will be among the half million people that will receive clean electricity from the country’s first thermal solar power plant.  The 140 MW utility scale solar power plant is located in Kuraymat and will start generating solar electricity in February 2011.

  According to Solar Paces:

  The Kuraymat project site is nearly 90 km south of Cairo and was selected due to its uninhabited, flat desert location, high-intensity direct solar radiation (2400 kWh/m2/year), and its proximity to an extensive unified power grid, expanded natural gas pipelines, and sources of water (the River Nile).

  With solar energy to light up Egyptian villages, its about time the quality solar resource is used to power the lives of so many people.

  Sunset Reservoir Solar Array in San Francisco

  Across the United States, cities and states are establishing goals to encourage a switch to renewable energy.  But no one has gone as far as the City by the Bay.  San Fransisco has made it a goal to be 100% clean energy powered by 2020.  That’s just 9 years away!

  San Francisco mayor made the announcement during the unveiling of the Sunset Reservoir solar array.  The new, utility scale solar power array is comprised of 24,000 solar panels and will triple the amount of solar power produced by San Francisco currently.   The Sunset Reservoir facility will sell solar electricity to the San Francisco Public Utilities Commission, saving the PUC more than $26 million over the next 25 years.  In addition to the clean energy, the installation will create many green jobs.

  But the Sunset Reservoir alone will not be the factor to help San Francisco meet its goal to be 100% clean energy powered by 2020.

  Sedona Red Rock High School in Arizona gets solar panels

  Solar panels installed at Sedona Red Rock High School in Arizona were unveiled this week!  Using over 3,800 Kyocera Solar PV panels, Kinney Construction Services completed the solar electric system as part of the Sedona-Oak Creek Unified School District Alternative Energy Project.

  The Sedona, Arizona school district is turning to solar power to help it save money and the environment.  In addition to the rooftop solar panels, the district is installing solar hot water and geothermal technologies.  What a great learning experience for the kids!  In fact, an educational PV monitoring system will show students exactly how much solar power is being generated in real time.

  Mike Thomas, Project Manager of Kenny Construction Services, noted:

  “The educational component for the students is going to be really intriguing.  Students will be able to compare different types of photovoltaic systems, including thin-film and multicrystalline technologies, and see the difference in electricity production of fixed versus tracking solar arrays.”

  The 806 kilowatt PV panel system at Sedona Red Rock High School is just the beginning.  Solar panels will also be installed on the school district office and at West Sedona School.  At the high school alone, solar panels will offset CO2 emissions in the amount equivalent to taking nearly 200 cars off the road each year.  Solar energy generated would be enough to power over 125 residences.

  World's largest building integrated PV system to be constructed in China

  Yesterday, Astronergy (also known by the name of its parent company, Chint Solar) announced that the largest photovoltaic system in the world would be constructed in China next year.  To be located at the Hangzhou East Railway Station, the 10 MW solar panel system will be grid connected and fully building integrated.

  The cost of the largest photovoltaic system will come from funds from the Golden Sun Program and National Solar Photovoltaic Building Demonstration Projects.  According to a press release:

  The station, located in East Hangzhou, will serve as a hub for high-speed rail, subway, buses, taxis and other forms of transportation. The PV project will integrate grid-connected power generation into the building’s infrastructure and will make full use of the building surfaces and roofs, as well as other surfaces.

  The solar panels at the Hangzhou East Railway Station will cover 148,000 square meters and will generate over 9,800,000 kilowatt hours (kWh) each year.  When it begins operating, the solar panel system will replace 3277 tons of coal and reduce CO2 emissions by 8095 tons.

  Its exciting to think that the train station and the world’s largest photovoltaic system will be operational by the end of 2011.   The hope is that the project becomes a model for other solar installations across China.  Dr. Liyou Yang, CEO of Astronergy, stated:

  “By bringing together two very necessary elements of sustainable cities- efficient transit and clean energy, we are setting an example for cities worldwide that sustainability is, in fact, achievable.”

  Astronergy is a leader in renewable energy development with the goal of bringing its photovoltaic (PV) solar power product line to global markets.

  Solar panels on top of Anheuser-Busch's Newark, NJ facility

  Solar panels on the rooftop of Anheuser-Busch’s beer manufacturing plant in Newark, New Jersey help generate clean solar electricity for operations.  Famous for its Budweiser beer, Anheuser-Busch has installed 3,000 photovoltaic (PV) solar panels over 65,000 square feet of its facility’s rooftop.

  Its the second time that the company has installed rooftop solar panels at its facility.  Last year, a solar array was added to Anheuser-Busch’s Fairfield, California brewery.  That makes it one of the largest users of solar power in the United States brewing industry!

  Anheuser-Busch has entered a power purchase agreement with Orion Energy Systems, under which Orion installed and owns the solar panels on the rooftop and Anheuser-Busch will purchase reduced-cost, clean solar electricity from Orion.

  

  Rooftop solar panels at Anheuser-Busch's facility in Newark

  The general manager of the Anheuser-Busch Newark beer manufacturing plant, Kristopher Scholl, commented:

  “New Jersey is quickly becoming the No. 2 producer of solar energy in the country and Anheuser-Busch is proud to be among the leaders in our state in use of this technology.”

  Cheers to Anheuser-Busch for being a leader among beer manufacturers in solar energy!

  Chicago Home Designed to Hide 48 Solar Panels

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  

  Beautiful design of LEED-platinum, solar powered Chicago home

  Installing solar panels on your home that are not visible is practically like having your cake and eating it too.  Most people find solar panels unattractive (which is why many homeowners associations do not allow them outright), but the significant energy savings and the satisfaction of reducing your carbon footprint are two things that most of us wish to have.

  However, a new Chicago home was designed to hide the 48 solar panels that provide clean, renewable-sourced electricity for its homeowners.  Michael Yannell worked with architects to draw up plans for his 2,675 square foot green home, which not only included hidden solar panels, but also achieved LEED platinum rating by the U.S. Green Building Council.

  

  Hidden solar panels on Chicago home

  Can you believe that this Chicago home is so green that it generates more energy than it uses?  That’s right!  With 48 solar panels, its a 10-kilowatt solar installation.  In addition to PV panels, the home includes a solar hot water system and a geothermal HVAC system.  This Chicago home is basically off-grid!

  In case you were wondering about the cost of a LEED platinum home like this one, Yannell paid $1.6 million.  Worth every penny to save energy and the planet!

  Will the Pope get a Solar Powered Popemobile?

  I guess the Pope wants to jump on the bandwagon when it comes to electric vehicles.  The Mercedes Benz car in which Pope Benedict travels will soon run on the energy of the sun – and maybe the Son, too.  A solar powered Popemobile is in the works.

  The Pontiff wishes to cut down on on CO2 emissions and turn to clean, green fuel.  Using solar panels to charge up the battery of an electric Popemobile is the Pope’s desire.  Recently, a Vatican spokesman said they would gladly accept a donated solar powered electric Popemobile if any automaker is moved to create one.

  A solar powered Popemobile would add to the solar installations already in place at the Vatican.  Solar panels cover the main auditorium to generate clean electricity and a solar cooling unit exists in the cafeteria.

  So – the race is on for a collaboration to create a solar powered Popemobile!  C’mon electric car manufacturers!

  Federal Solar Grant Program Ending Soon

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  

  Commercial solar installations could stall with the expiration of a federal solar grant program

  Time is running out for owners of commercial properties!  A federal solar grant program is ending soon – December 31, 2010 to be exact.  That deadline has property owners scrambling to install solar panels now so that they can take advantage of a solar incentive program that allows up to 30% of the cost of solar panel systems.

  To be eligible for the grant program before it expires, you must enter into a contract for a solar panel system and pay at least 5% of the cost of the project by December 31, 2010.

  Originally adopted as a federal tax credit, the Legislature converted the program into a Treasury grant program so that commercial property owners didn’t have to wait to get the rebate until tax time.  Now, owners can receive a check within 60 days of solar panel installation.

  However, despite industry efforts to get Congress to extend the federal solar grant program, it remains set to expire at the end of the year.

  The federal solar grant program has been quite successful in stimulating solar installations across the country.

  According to the U.S. Partnership for Renewable Energy Finance, investments in solar panel systems doubled from 2008-2010 when the grant program was in place.  Over 1,100 solar energy systems have been financed in part by the federal solar grant program, per statistics of the Solar Energy Industries Association.

  A 30% reduction in the out-of-pocket costs for solar power systems is no small matter when it comes to commercial properties.  The size and scale of solar panel systems that can be installed is much greater than without the help of federal funds.  Not only do the grant monies encourage commercial property owners to go solar by minimizing the capital expenditure outlay required at the outset, but owners are also able to recoup investments much more quickly – often within 4 or 5 years.

  If Congress does not renew the federal solar grant program by the end of the year, it will revert to an investment tax credit good through 2016.  And commercial investment in solar panel systems is expected to decline dramatically, as a result.

  What can you do?  Write, email or call your Congressperson and ask them to extend the federal solar grant program!

  Kohl’s Installs Solar Panels on 100 Retail Stores

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  

  Kohl's Solar Panels help lower costs for consumers

  Put aside worries about Christmas shopping and winter energy bills and consider this news:  Kohl’s has installed solar panels on 100 of its retail stores.  The new systems generate clean solar electricity and help save money for the retailers, which means lower prices for all of us over time.

  Of the 100 Kohl’s stores that have installed solar panels, the most recent outlet is in Mays Landing, New Jersey.  In Pennsylvania, 7 more Kohl’s stores will get solar panels in the next 4 months, by the end of Q1 of 2011.

  Each of the 100 Kohl’s installing solar panels have used about 1,400 panels that defray 40% of the electricity and energy usage at each store – that is a total of more than 140,000 solar panels on the retail stores!  And the investment in solar energy has already saved Kohl’s about 50 million dollars.

  By the end of 2010, Kohl’s expects to be carbon-neutral.

  According to Ken Bonning, a Kohl’s senior manager:

  “Our 100 solar locations, commitment to build 73 Leadership in Energy and Environmental Design (LEED)-certified locations and 500 Energy Star stores demonstrate our ongoing commitment to sustainability with meaningful results.”

  The impact of Kohl’s installing solar panels on 100 retail stores is sure to be far reaching.  Consider these facts:

  • Kohl’s has stores or distribution centers with solar panels in California, Wisconsin, Connecticut, New Jersey, Maryland, Oregon, and Colorado.
  • Kohl’s reportedly uses the most solar panels of all retail companies in North America.
  • In January of 2010, the company achieved 100 percent green power, according to their press release. Nationwide Kohl’s operates just over 1,000 stores in 49 states.

  For Widespread Adoption of Solar, Call Sarah Palin?

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  

  Sarah Palin could change mindsets about solar power?

  I found a great blog post at One Block Off the Grid (1BOG) that I simply needed to pass along to my readers.  Not only is it helpful, but there are some great arguments and its pretty funny to read, as well.

  I have to admit that the title peaked my curiosity:  Why Solar Can’t Go Mainstream without Sarah Palin.  If you too are scratching your head – wait!  It makes sense.  Consider these points by the author:

  1.  Solar power is considered to be a lifestyle choice for rich, liberal environmentalists the likes of Al Gore and Leonard diCaprio.

  2.  Before solar can go mainstream, we have to change perceptions so that people can see that it makes sense for the masses, and that there is a huge economic payback for doing so.

  3.  In the U.S., less than 1% of homes have solar panel systems installed.

  4.  There are places in the United States where the solar incentives and financing options are so generous, you’d basically have to be insane not to go solar.

  5.  Solar power needs a spokesperson that can literally change the national mindset that prevents people to make the switch.  Someone that can show us that “regular” people like you and me are going solar, and how awesome it is.

  

  Promoting solar panels as a convenient, affordable way of life

  6. Sarah Palin is a great example of a “game changer” who could change perceptions about solar from highbrow liberal luxury to one of the everyday items regular families can afford.  The 1BOG blog post examines Palin’s political stance and describes how she could apply them to promote solar conversion:

  We should not reward poor financial decisions. (Sep 2008). House flipping and predatory lending put us in a bad spot. What about instead investing in your home for years by improving it with something that saves you money on your power bills? It’s forced savings, it’s frugal and it’s the most stable, low-risk investment out there (solar panels are essentially made of sand. They’re silicon. They don’t break. There are panels that were installed in the 1960’s that are still pumping out money).

  Energy is a foundation of national security. (Sep 2008). Each panel is that much new energy generated inside our country and not imported. Sure, we get most of our coal from inside the country, but electric vehicles have already started, and that means less oil, and we can generate the power for those from the sun. This isn’t some crazy pipe dream, it already works and so do the economics behind it.

  Leverage job-training dollars through voc-tech curriculum. (Nov 2006). Yes, there’s lot of heat about our subsidies going to other nations. You can’t do much about that, you gotta close your eyes and have some faith. We’re a capitalist nation. If their products are cheaper, they’re going to put those in in their large products because it benefits the bottom line. But you know what you can never export? Jobs putting in renewable energy projects. If you want something to replace the auto industry to keep us a global powerhouse, it’s this.
  

  Favorite movie: “Hoosiers.” We’re coming from way behind Germany, Japan, Spain, and now China in solar. We are the underdog.

  If Sarah Palin is unavailable, or otherwise unwilling to promote widespread adoption of solar, 1BOG suggests we turn to Jim Cramer, Donald Trump, Glenn Beck or Oprah.  Put aside the boring, predictable environmentalists and get some people that definitely can cause a stir.

  Residential Solar Industry Growth

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  

  Residential Solar Industry Growth

  A recent white paper published by SunRun discusses residential solar industry growth and includes projections for the future of solar energy.

  Over the past year, the number of people with jobs in the solar industry doubled to over 100,000 in 2010.  Further increase in solar jobs will continue into 2011, with a projected rise of an additional 26%.  In short, the solar industry is creating employment opportunities faster than the overall economy in the United States.  Residential solar demand is responsible in large part for the increase in the number of solar jobs.

  With more homeowners installing solar panels, demand rises for both solar products and qualified installers.  In turn, the more solar industry jobs there are, the more people are available to serve the very consumers that are wishing to go solar.  Its a positive “vicious circle.”  As described in the SunRun white paper on residential solar industry growth:

  “SunRun not only directly employs workers, but also partners with 25 installation companies across the country, that in turn employ 3,000 green collar workers. The more homes that install solar, the more installation crews are needed, and the more tools and inventory are required. One local job is created for every six homes that go solar. The impact of residential solar extends from the panel manufacturer to the auto repair shop that services the installation trucks, to the local coffee house that keeps the installers on their toes.

  When a homeowner installs a solar system on their home, they automatically invest in green jobs and clean energy companies, ranging from those researching new solar technologies to installing panels in their neighborhood. A Navigent Consulting study found that for every six homes that go solar, one local green job is created.”

  High efficiency solar panels from Boeing

  Boeing has long been known for its leadership in aerospace.  Now, its using its engineering expertise in the renewable energy field.  In just a month or two, we will likely be seeing high efficiency solar panels from Boeing.

  Boeing’s wholly-owned subsidiary Spectrolab has created C3MJ+ solar cells to be used in PV solar panels and other solar products.  Perhaps the most exciting features of these high efficiency solar panels is that they can convert over 39% of sunlight into solar electricity!  That statistic shatters the previous PV solar panel record for efficiency set by SunPower Corporation (24.2%).

  If you are not familiar with Spectrolab, the company is already supplying solar power to 60% of the satellites orbiting Earth.  Partnering with Boeing, they hope to produce 10 million of the high efficiency solar panels.

  Solar Technology Lowering Solar Panel Costs

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  

  Residential solar power is getting more affordable

  Many of us want to switch to solar power, but we’re worried about the expense.  Fortunately, new solar technology is lowering solar panel costs.  That, coupled with generous governmental incentives is helping to bring solar energy to more people worldwide.  As we look for renewable energy options that are affordable and efficient, solar may be just the option to move us away from fossil fuels towards a brighter future.

  I discovered a recent article at Solar Power Authority that describes new solar technology that is lowering solar panel costs.  Kriss Bergethon, a reporter who lives off the grid with his wife and family, contributed to the article.  Be sure to visit his Solar Panel Store online.

  

  Thin film cells are used in solar roof shingles

  The following is an excerpt from the article, “Three Innovations that are Lowering the Cost of Residential Solar.”

  1. Thin-Film Cells

  Instead of the large, rectangular solar panels you typically see mounted on rooftops, thin-film solar cells are more flexible, lighter and require less energy to produce.

  Thin-film solar is a completely different take on solar cells. The cells themselves often come in a roll and the manufacturing process is similar to a printing process. This dramatically reduces the cost of solar power. Panels that use traditional crystalline technology still cost in the $2/watt range. Thin film cells cost closer to $1/watt and that price is falling quickly.

  You’ll see thin-film solar cells in building-integrated photovoltaics options like solar roof shingles (pictured to the left).

  2. Micro-Inverters

  When you install solar panels, you also need an inverter.  Inverters take solar energy which is absorbed as direct current (DC) and converts it into the alternating current (AC) power you get when you plug in an appliance.   Inverters have traditionally comprised at least 1/3 of the cost of a solar power system, with basic models costing around $3,000 (solar panels not included!)  But get this:

  Microinverters have changed the equation dramatically. Now, for less than $200, you can have an inverter on each solar panel, and have a system that consists of as little as one solar panel if you wish. That means the entry point for installing a solar power system is now as low as $1000. Many people start with just one or two panels, and add on a panel or two each year.

  Microinverters also help increase solar panel efficiency, while minimizing installation time.

  

  Solar panel racking improvements can reduce costs

  3. Flexible Racking Solutions

  In order to cut down on solar panel costs, changes need to be made with respect to racking systems.  Up to 1/4 of the solar panel equipment costs and 3/4 of the labor costs are due to solar panel racking systems.

  That is about to change, however, as companies are developing racking that eliminates rails, while allowing for quicker grounding system installation.  Check out Zep Solar for more information.

  In the past few years, solar panels have fallen in cost by more than 50%.  Government is encouraging the switch to renewable energy, offering rebates and other incentives that lower the costs even more.  With new solar technology also lowering solar panel costs, we may one day see most homeowners going solar!

  i-Slate solar powered personal computer

  We have solar powered cell phones, so why not solar-powered personal computers?  The answer is – yes!

  The i-Slate is a solar-powered tablet PC developed by Rice University and Nanyang Tech University of Singapore.  The solar-powered personal computers are currently being tested by schoolchildren in Indian villages.  The solar gadget stands to significantly improve educational opportunities for 100 million students in rural villages.

  For remote villages located off-grid, the lack of electricity means that devices we take for granted simply have not been available.  Can you imagine growing up in the 21st century without use of computers to help you learn and connect to the rest of the world?  That doesn’t have to be the case with the i-Slate, which is charged with solar energy, and requires very little power to operate.

  According to the Times of India:

  “India’s full economic potential will only be realised with sustainable, low-cost technologies that benefit all segments of the population,” said Krishna Palem, of Rice University who is leading the effort to replace the hand-held slates that millions of children use in schools today. I-Slate , Palem’s brainchild, is in development at Institute of Sustainable and Applied Infodynamics (ISAID) which is based at NTU. The first prototypes of the I-slate , which were built by a team that included three Rice undergraduates, are set to undergo their second round of tests in India later this month.
  Palem, who directs ISAID, said the device is the first of a series of electronic notepads being built around a new class of green, power-stingy microchips that use a fraction of the electricity of today’s processors.

  The solar-powered personal computers were tested in August 2010 by students aged 10-13 years old  The slate PCs use solar power from embedded solar panels like those on some cell phone models and handheld calculators.

  With the i-Slate in the hands of millions of Indian village children, we can expect improved education, at little environmental cost!

  Solar panels generate electricity for Joseph Ascencao to stay in touch on his global bike ride

  Any time you have a person planning to circumnavigate the globe by themselves, you have to wonder… how will they stay in touch?  What if there is an emergency?

  For Joseph Ascencao, he is relying on solar power to energize his solo bicycle trip around the world.  Now, we know that he won’t actually cross the oceans on his bike, but the journey will take him through each of the continents (except Antarctica) over the next 4-5 years.  To charge up his cell phone and keep tunes playing on his iPod, Ascencao has installed solar panels on his bicycle.

  The trek started in August from Providence, Rhode Island and followed the eastern seaboard to Key West.  He’s now heading to Texas where he will take a break with some friends.  From there, Ascencao will ride down to Brazil to meet another group of friends.  The entire trip will cover more than 57,000 miles.

  Solar panels mounted on his bicycle will generate electricity to keep his electronics humming and allow Ascencao to stay in touch with supporters along the way.  In fact, the solo bicycle trip is being recorded through a camera installed on his helmet.

  Solar powered LED street lights

  LED street lighting can better illuminate roads and walkways, and save municipalities money.  Using funds from the American Recovery and Reinvestment Act of 2009 , cities and counties across the nation are turning to solar powered street lights, as well as other LED street lighting options.

  Compared to “typical” street lights, LED lights use significantly less energy and last longer.  Even if they are slightly more expensive at the outset, they pay for themselves in savings over time.

  Is it any wonder that solar powered LED street lights are appearing on more roadways than ever before?

  Not only municipalities, but private property owners use LED street lights to illuminate parking lots and pathways.  School districts are increasingly choosing LED lights to brighten sports stadiums, as well.

  Of course, with the Christmas season upon us, LED holiday lights are also glowing on homes, buildings and trees!

  When solar energy is used to power LED lights, there is no need for trenching and wiring.  Often, solar panels are positioned at the top of the street lamp itself.  Ultraviolet light is absorbed during the day and then, at night the lights come on automatically and glow until dawn.

  Sounds like a really bright idea to me!

  i-Cool Solar panels keep truck interior cool with solar energy

  We’ve told you about solar powered air conditioning units for your home, but now the idea is hitting the road!  The iCool Solar is a solar powered air conditioning unit for trucks, developed by Mitsubishi and Nippon Fruehauf.  It operates when the engine is off, using solar power captured by photovoltaic thin film cells to generate energy to cool the cabin of the truck.

  The iCool Solar consists of solar panels that are attached to to top of the truck trailer (shown above), a battery for storing solar electricity generated by the panels, and a 900W air conditioning unit.  But don’t go looking for one of these solar powered air conditioning units yet.  They will not be commercially available until spring 2012.

  Relying on solar energy, rather than battery life, to run the A/C while the truck is turned off preserves battery life.  It also cuts down on fuel consumption and cost.  A 10-ton truck can use nearly 400 gallons less of fuel each year with the iCool Solar.

  

  Solar powered air conditioning for trucks

  Mitsubishi Chemical estimates that if all the trucks in Japan used the i-Cool Solar, CO2 emissions could be cut by 1.65 million tons in Japan alone.

  i-Cool Solar is also being developed in a smaller version for use in passenger vehicles.

  The Cost of Solar Power

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  

  What goes into the cost of solar panels?

  Its one of the most searched for phrases on the Internet when it comes to energy: “what is the cost of solar power?”  Yes, people are considering renewable energy more and more these days as a way to save money, as well as the environment.  Generating your own electricity is both efficient and reliable, which also makes it an attractive option for many homeowners.

  But when it comes to the cost of solar power, many people are put off.  If you are planning on purchasing your own equipment (as opposed to a solar panel lease), the upfront costs can be close to $50,000.  But what does that price cover?

  Your overall investment for a solar electric system includes:

  • 60% for the solar panels themselves – based on photovoltaic panels (silicon is expensive)
  • 10% for the solar inverter (it takes direct current from sunlight and converts it into alternating current for us to plug int0)
  • 15% for parts necessary for installation (wires and racks, etc.)
  • 15% for labor

  Does that still sound daunting?

  If so, you’re not alone.  But don’t forget the value of solar tax incentives and credits, which can defray significant amounts of the cost of solar power, plus the peace of mind of knowing that – even though you are paying for 25-30 years of electricity upfront, you will save significantly more on a monthly basis over the life of your solar electric system.

  High Performance Solar Roof Shingles

   » ‎ Solar Power -- Green Energy

  Tags:    [edit]

  

  High performance solar roof shingles from Dow

  One of our favorite ways to go solar is with low profile, but high performance solar roof shingles.  From the manufacturer Dow comes a residential solar shingle that has been certified by Underwriters Laboratories (UL).

  Introduced in October 2009, Dow’s Powerhourse solar shingle is an affordable roofing option that can help cut your electricity bills and carbon emissions.  The sleek profile of solar roof shingles blend right into your regular roof tiles, minimizing the aesthetic impact.  Now, the residential solar shingles will be available for purchase in 2011!

  According to Dow’s website:

  But, why is our solar solution revolutionary? First, it’s a residential shingle – in both its installation technique and in the roofing protection it provides. In addition, it generates solar electricity by integrating solar cells into the design. In other words, the shingle is the solar panel, and the solar panel is the shingle.

  Solar shingles are an example of the growing market in building integrated photovoltaics (BIPV) – construction materials that include solar cells to generate clean solar electricity.  Consider these features of Dow’s high performance solar roof shingles:

  • Quick, easy installation
  • Minimal roof penetrations, compared with traditional solar panels
  • Sleek profile that integrates with existing asphalt shingles on your roof
  • Comprised of thin film solar cells (CIGS: copper, indium, gallium, diselenide)

  The UL certification is one of the final steps needed to bring Dow’s Powerhouse Solar Shingles to the market early next year.  Certification confirms the ability of the solar roof shingles to meet electrical codes and photovoltaic connections.

  The Sol Cinema is the world's smallest solar powered movie theater

  First, there were solar-powered movies, and now there is a green cinema in which to watch your favorite flicks!  The Sol Cinema is the world’s smallest solar-powered movie theater that has an even more minuscule carbon footprint.  In fact, the facility is 100% solar powered by two 120W solar panels.

  Shown above, the Sol Cinema has room for eight adults or twelve children, and probably some popcorn as well.  Owned and operated by the media arts charity Undercurrents, the world’s smallest solar powered movie theater is housed in a converted 1960s caravan.

  According to Sol Cinema’s website:

  The Sol Cinema has been lavished with pride and style. We use an LED projector showing short movies in cinematic surroundings.
  We use state of the art lithium batteries to store the energy from the Sun to power the cinema all day and night. Our photovoltaic panels harness the sunlight, even as the films are being shown so we never run out of power.

  If you’d like to rent the world’s smallest solar powered movie theater for a community event or private gathering, you can contact The Sol Cinema here.

  Solar Tax Credit: How it Works

  Solar panels can help you save money on federal income taxes

  You have probably heard the news that solar panel prices have fallen by as much as 50% in recent years, as the government has made it more affordable to go solar.  The Federal Investment Tax Credit can help you save when you install solar panels by allowing up to 30% off the cost of a solar panel system through a credit on your federal income tax bill.

  Here’s how the solar tax credit works.

  Let’s run some numbers for illustration.  You are going to invest $10,000 in a solar hot water heating system in 2010.  When you prepare your personal income taxes in spring 2011 (for the year 2010), take your final tax bill – the amount that the government states you should be paying in taxes after calculating gross income and any deductions, and then take $3,333 off that number.

  Does that mean that you can get $3,333 back if you had more money withheld than you owe in federal taxes?

  Sorry, but no.  You must actually have a tax bill against which the solar tax credit is offset.  But don’t despair – you can roll the credit forward to the next year and make some adjustments so that the credit can be applied properly.

  Your best bet is to consult a CPA or other tax advisor to make sure you can claim 100% of the solar tax credit within 2 years.  With our example above, the credit must be claimed on either 2010 or 2011 federal tax filings.  Otherwise, its gone.

  For additional information, Scott Gordon, Vice President of HelioPower, wrote a comprehensive blog post explaining Federal Tax Credits.

  Solar Powered Hollywood Sign?

   » ‎ Solar Power -- Green Energy

  Solar Powered Hollywood Sign!

  Since 1923, the iconic Hollywood Sign has stood above Hollywood Hills (originally to indicate the location of the residential neighborhood).  Anyone who comes to Los Angeles to chase a dream of stardom – or perhaps just to try to get a glimpse of the rich and famous – will look up at the famous sign that has been in the same location for nearly 90 years.

  As a “sign” of the times, there is now a movement to create a solar powered Hollywood sign.  The letters spelling out the word would not be replaced as they were in 1978, but solar panels would be added to the landmark to raise awareness about solar power and other renewable energy resources.  Hundreds of photovoltaic (PV) solar panels, spanning 450 feet wide, and reaching 45 feet tall, would bring new meaning to the term “star power.”  Drawing on our own, closest star – the sun – the message a solar powered Hollywood sign would send is that we can literally power our lives with clean solar electricity.

  Members of the Hollywood Sign Trust initially gathered on Earth Day 2009 to consider the proposal which has support from Deep Patel, the founder and CEO of GoGreenSolar, a solar advocacy group, radio legend Pat ‘Paraquat’ Kelley, Brian Sirgutz, the CEO of CauseCast, KevinWall, the founder of Live Earth, Terry Nunn of the rock group Berlin, Brooke Gardner Fedro of Andre Agassi’s foundation, T. H. Culhane of Solar CITIES; and Maria Menounos of Access Hollywood.

  Today, 18 months later, a survey is underway as part of a feasibility study to crease a solar powered Hollywood sign.  If you’d like more information or to provide support to the cause, visit the group’s Facebook page!
