  Tools to Help You Switch to Solar Power

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  Going solar is easier for homeowners with a few key resources.  Here are a couple of tools to help you switch to solar power with less hassle and expense:

  1.  Tap into Solar Incentives

  One of my favorite resources is the Database of State Incentives for Renewables & Efficiency (DSIRE), which lists state rebates and solar power incentive programs, as well as information on federal solar incentives.  The site is funded by the U.S. Department of Energy’s Office of Energy Efficiency and Renewable Energy.  There, you can find information on state, local, utility and federal incentive programs that can help you cut the cost of residential solar panel installations by as much as 60-80% off the retail cost.

  2.  Determine how Much Grid-Based Electricity You Can Offset with Solar

  Here is another tool from the U.S. government that can help you switch to solar power.  Part of your analysis will be to determine how much electricity you use at home, and then how much you can offset with solar.  The website of the U.S. Energy Information Administration (EIA) includes statistics about the amount of electricity the average American home demands.  In addition, check out the Energy Department‘s information about considerations to make before going solar.

  3.  Find the Best Solar Panel Manufacturers

  This may be surprising, but you can find the top solar manufacturers in the U.S. on Wikipedia.  The site includes a list, put together based on an annual report by Photon Magazine.  Additional information on annual solar manufacturer rankings is found at Solar Buzz.

  4.  Log onto Solar Chat

  These days, you can find a chat room on just about any topic!  Why not connect with other people that are thinking about going solar, or who have already made the switch?  Try the online forum at Solar Panel Talk.  You can find people to chat with on DIY solar panels, going off-grid, solar panel leases and purchasing/installing conventional residential solar systems.

  5.  Use a Solar Price Calculator

  Online calculators can help you determine how many solar panels you will need for your energy demands and what a system will cost.  There are a number of solar price calculators available and you can find links to many of them at CalFinder.

  Cut Costs of Solar Power by Reducing Permitting Fees

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  Solar panels are an investment, even with incentives, tax rebates and the recent falling prices.  Yet, there is one area in which costs of solar power can be reduced – trimming permitting fees and streamlining the process.

  

  Permitting fees increase the cost of solar panels

  In order to install residential solar panels, you will need a building permit (and possibly other land use permits) from your local permitting authority.  The process takes time, adds delay and hassle, and also costs money in permitting fees, and potentially the cost of working with a solar installer that is familiar with the process and can help you navigate it.

  Because of this hurdle toward broader acceptance of renewable energy, the U.S. Department of Energy is making $27 million available to support local and regional governments streamline the process of implementing solar power projects.   The result will be to cut carbon emissions as fewer people use fossil-fuel based electricity.  Homeowners that install solar panels also enjoy reduced power bills each month.

  As part of the SunShot Initiative the DOE is offering a $12.5 million challenge to encourage cities and counties to compete to streamline and digitize permitting processes by:  standardizing permitting processes, updating planning and zoning codes, improving interconnection and net metering standards and, finally, increasing access to financing.

  The DOE will also use $15 million to fund one or two recipients to create tools for local governments to streamline and expedite the process of installing solar energy in the three areas: regulatory and utility solutions; codes, standards and processes and software design tools and databases.  Department of Energy Secretary Steven Chu commented:

  “These investments under the SunShot program can help to transform the solar energy industry by addressing significant challenges to solar energy deployment, including permitting and installation.  Innovations in IT and local business processes, such as online permit applications, can deliver significant savings for solar energy systems and will help America to compete globally in this growing market.”

  Just this week, the Long Island Power Authority (LIPA) announced a unified solar permitting process with Nassau and Suffolk County that will start in fall 2012.  Known as the Long Island Unified Solar Permitting Initiative (LIUSPI), this new campaign is focused on developing a model process that could be used by all municipalities throughout Long Island to effectively and uniformly handle the application for and approval of residential solar electric and solar hot water systems in each respective jurisdiction.

  Arguments Against Solar Power and the Truth About Solar Energy

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  More and more people are turning to renewable energy for their electrical needs.  Yet, there are still many that focus on the disadvantages of solar, rather than the freedom it offers.

  

  The truth about solar panels

  The following arguments against solar power are often made, but are largely without basis.  Consider these five complaints, as well as the truth about solar energy:

  1.  Coal is Cheaper Than Solar Power

  So-called grid parity – the point at which solar power is as inexpensive as fossil-fuel based electricity – has already been reached in Hawaii and will soon be reality in California and Arizona, as well as states where utility bills are sky-high (i.e., New York).  This means that coal will not always be cheaper than solar power.  Nor should we only consider a direct cost comparison.  Failure to account for long-term impacts of the continued burning of fossil fuels and associated expenses is nothing but short sighted.

  2.  Large Utility Scale Solar Power Farms Take Up Too Much Land

  While there is a place for utility scale solar power, many of our electrical needs can be met at a distributed generation level.  That is, by generating power right at the location where it is used.  Rooftop solar panels can effectively generate most, if not all of the power required for residential or office uses.  The more people that employ such solar systems, the less desert land will be required for large solar power plants.

  3.  Residential Solar is Too Expensive

  Not true any longer!  Prices for residential solar panels have fallen dramatically (50% or more) in the past 2 years, while tax rebates and incentives continue to be offered.  In addition to lower retail costs, homeowners have the option of leasing solar panels or purchasing solar electricity pursuant to a power purchase agreement with no money down.  Monthly power bills are lower and set at a fixed rate for the life of the system (20-30 years).

  4.  The Government Should not be Subsidizing Solar Power

  This is one of the most common arguments against solar power, in part as a backlash against the Solyndra debacle in 2011.  Yet, there is no a single energy industry that is not subsidized by the federal government.  Homeowners can obtain up to 30% off solar panel costs through the federal incentive program.

  Did you know that fossil fuel subsidies are an astounding 13 times higher than renewable energy’s. A 2011 International Energy Agency report states that “Subsidies to renewables and low-carbon energy technologies can bring long-term economic and environmental benefits.”

  5.  Solar Panels Lower Home Values

  This argument is often made by homeowners associations opposing the installation of residential solar panels within a subdivision.  The reasoning is that rooftop installations have negative aesthetic impacts on the appearance of a home.

  Whether or not you object to the appearance of solar panels, the truth is that they actually raise the value of a home.  For every $1 you save on annual energy costs, your home is worth an extra $20.  That means if you save $1000 (less than $100 a month), you have an instant equity boost of $20,000!  In addition, homes with solar panels sell faster and for more money.

  Now that you know the truth about solar energy, perhaps its time to consider installing solar panels this year!

  Install Solar Panels for a Net Zero Energy House

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  

  Net Zero Energy House with Solar Panels

  This amazing house in Ann Arbor, Michigan (shown to the left) is 110 years old and yet operates without the use of any grid-based electricity.  Its owners decided to install solar panels for a net zero energy house.

  While net zero homes (residences that generate all the power required for their operation on site) are becoming more popular, the home above is the oldest net zero energy home in the U.S.

  Following extensive refurbishing and retrofitting, the roof is covered in solar panels that generate 12,500 kilowatt-hours (kWh) each year.  Of that, only 10,000 kWh was required to keep things running and the balance was fed back into the grid via net metering.

  If you are considering installing solar panels on your home this year, keep in mind that prices are lower than ever – about 50% less than just a few years ago.  In addition, solar tax rebates and other incentives will be phased out in the near future, so act now!

  This net zero energy house cost about $47,000 to renovate, saving the owners thousands each year on utility bills.  In addition to rooftop solar panels, additional insulation was installed, along with insulated glass.  Low pressure plumbing minimizes water usage, too.

  To learn more about net zero energy houses and how these Michigan homeowners installed solar panels on their 110-year old home, watch this video:

  Solar Hot Water Heaters: Radiant Heat for Free Hot Water

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  If you are thinking about installing solar panels on your home but concerned about the expense, have you considered solar thermal panels?  Solar hot water heaters use specialized solar panels to heat water for domestic use, without the need for conventional electricity.

  

  Panels for Solar Hot Water Heater

  Heating water for household uses like bathing, washing dishes and laundry is one of the most energy-intensive activities, accounting for significant percentages of monthly electricity bills.   If you own a swimming pool, hot tub or spa, keeping the water at a comfortable temperature can also be expensive.

  That’s where a solar hot water heater comes into play!  Water is piped through a system that uses thermal energy from sunlight to warm it for free, where it is then stored in a specialized hot water tank for use.

  An active solar thermal panel hot water system uses electrical pumps to move the water through the system, whereas a passive solar hot water system relies on thermal dynamics (cold sinks and heat rises) instead of pumps.

  Solar hot water heating systems have several advantages over solar photovoltaic (PV) panels, which generate electrical power:

  1.  They are less expensive  – about 1/3 the cost of solar electric PV panels

  2.  They are more efficient – with the ability to convert 3 times as much energy for use as PV panels

  3.  The return on investment is about 1/2 that of PV panels (4-8 years)

  4.  The average homeowner can save 60-70% off their average annual hot water heating expenses

  In general, a solar hot water system is comprised of the following, and can be installed by a professional, or you can build one using DIY instructions:

  • Solar thermal panels (also known as solar collectors)
  • Rooftop mounting system for the solar thermal panels
  • Solar storage tank – a new solar hot water tank
  • Water pump and controls (not required for passive or thermosyphon systems)
  • Heat exchanger and expansion tank (only for closed-loop solar hot water systems)
  • Isolation valve
  • Backup Water Heater
  • Tempering valve – to make sure your solar heated water doesn’t get too hot!

  Solar hot water heaters are a good first foray into using solar energy because they are relatively inexpensive, allow you to save significant amounts on your utility bills and are low maintenance.  Whether you go with a DIY system or have one professionally installed, you can enjoy free hot water for years to come.

  Solar Power Grid Parity Predicted

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  Solar power grid parity is predicted in the U.S. within the next 10-15 years, meaning that the cost of solar electricity will be lower than traditional grid-based energy sources such as coal or gas.

  

  Solar power grid parity predicted

  We found this map published on the Energy Self-Reliant States website that shows solar power grid parity in most major U.S. metropolitan areas by the year 2027.  The figures are based on projected costs of retail utility scale electricity and continuing lowering of the cost of solar power.  Considering energy cost trends, solar energy will be cheaper than coal in a matter of just a few decades.

  The interactive map based on predictions of energy policy analyst John Farrell illustrates the U.S. cities that will achieve solar grid parity first, and those that will follow between now and 2027.  Based on current retail rates for electricity in regions across the nation, and the declining cost of solar power in recent years, Farrell predicts San Diego to be the first to achieve solar power grid parity in 2013, with New York City following in 2015. Just five years thereafter, Farrell expects 17 major metropolitan areas to reach solar grid parity in 2020, reaching 40 regions by 2027.

  Solar Power in India

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  Solar power in India is growing with some big, ambitious policies adopted by leaders aimed at dramatically reducing use of fossil fuels and turning to the ample resource that the country enjoys.

  

  Solar Power in India

  Two years ago, India announced plans to increase generation and use of solar electricity from approximately nothing, to 20,000 megawatts (MW) – the equivalent of energy required to power 20 million U.S. homes.  At the time, there were plenty of nay-sayers who claimed it could not be achieved.  Already, they are re-thinking their dour predictions.

  Currently, India’s solar power totals only about 140 megawatts, which can power a town of 50,000.  Of that amount, 10 megawatts is generated by the utility scale solar power project operated in Khadoda, India by Azure Power.  Azure sells the solar electricity generated by the 36,000 solar panel plant to a state-government electric utility.  The CEO of the company, Inderpeet Wadhwa, predicts that within just a few years, solar power will reach grid parity in India.  That is, it will be cost competitive with electricity generated by conventional means, including coal-fired plants.

  Analysts believe that India’s 20,000 MW solar power goal could even be reached before 2020.  This is due in large part to a dramatic drop in prices of solar panels.  Some manufacturers have slashed costs by 30-40% in 2011 alone, bringing the cost of solar panels to a mere $1 per watt.  First solar, based in Tempe Arizona, is the leading U.S. supplier of solar panels to India.

  Solar Panel Efficiency Can Be Increased Significantly

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  

  Solar Panel Efficiency

  Over the past 5 years, the price of solar panels has dropped dramatically while efficiency of solar arrays has increased significantly.

  Yet, it appears that the renewable energy revolution continues to make life better and cleaner for many of us!  The University of Texas at Austin announced this month that one of its solar researchers has discovered a method to further double solar panel efficiency up to 60%!

  Solar panel efficiency can be summarized as follows:  The term refers to the amount of solar energy that is converted to usable electricity after hitting a solar panel.  It does not need to be a bright, sunny day.  All you need is UV (ultraviolet) sunlight, filtered through clouds or even precipitation.  According to a recent article:

  An issue with regular photovoltaic panels is that much of the energy delivered by sunlight results in the conversion of “hot” electrons, which are too high-energy to be converted to electricity in silicon and are instead lost as heat. University of Texas Chemistry professor Xiaoyang Zhu and his team discovered that an organic plastic semiconductor could double the number of electrons harvested out of one photon of sunlight.

  Solar panel efficiency is currently about 30% for silicon photovoltaic (PV) solar cells.  But solar technology indicates that this figure can at least double, to reach 66% efficiency.

  The importance of this discovery is the potential of reaching grid parity – the point at which the cost of purchasing solar electricity is less than the price of fossil-fuel based power.

  Top Reasons to Switch to Solar Power Now

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  

  Reasons to Switch to Solar Power

  Have you been thinking about installing a residential solar system?  Well, now is the time!  The cost of solar panels has dropped more than 40% this decade, and more and more people have changed to solar.

  If you are still on the fence, consider these top reasons to switch to solar power:

  1.  Reduce Your Electric Bill

  Did you know that the average household in America spends over $1,400 each year on electricity?  The year 2010 marked the fifth consecutive year that utility rates have risen.  That means that homeowners are paying 20% more for electricity than they did only a half decade a ago.  Its time to keep more of that hard-earned cash for yourself, and protect against continued rising rates by switching to solar power.  In the first year following solar panel installation, most property owners realize 40% or more in electric bill savings.  These savings stay “locked in,” despite what happens to the economy and future electricity costs.

  2. Take Advantage of Sunny Skies

  Sunshine helps, but even brighter skies can generate ample solar electricity.  Generally speaking, solar panels are most efficient when exposed to direct sunlight.  However, ambient UV light is sufficient for solar panels to generate ample clean electricity.  If you are eligible for net metering, you can reduce your power bill to zero and even get paid for extra solar power generated during peak periods.

  3. Take Advantage of Incentives

  Currently, solar rebates and incentives offer  substantial savings on solar installation costs. The U.S. federal program can save you up to 30% off the retail cost to install a photovolatic (PV) solar power system. Most incentive programs have an expiration date, however.  In today’s political climate, continuation of many programs are uncertain.

  4. Combat Rising Electricity Demands

  Did you know that in the next 25 years, electricity demands will nearly double, according to a 2005 Energy Information Administration report.  Even though we are taking more and more steps to save energy, our consumption is increasing with the size of our homes, number of electronic devices and efforts to stay cool and comfortable year-round via HVAC.  By switching to solar power, you can off-set increasing demands, as well as cut down on energy demands through the insulating effects of installing solar panels on your roof.

  5. Save the Environment

  It is hard to continue to explain away the bizarre weather experienced around the world over the past decade.  Global climate change is real and its time to step up efforts to reduce CO2 emissions.  Switching to solar power can significantly help.

  Wait another 10-15 years, and it might be too late to reverse the trend.

  Hawaii Feed-in Tariff Makes Solar Power Affordable

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  

  Solar panels in Hawaii

  The Hawaii feed-in tariff makes solar power affordable for people looking to switch to the renewable resource.

  The program was started in 2009 by the Hawaiian Electric Company.  This type of solar incentive is unique, compared to other programs that make solar power affordable, as it pays consumers a premium rate for the excess solar electricity generated by a solar array that is fed into the grid.  Its similar to net metering, by providing a credit (or sum) for those property owners that generate more power than they use.

  The Hawaii Feed-in Tariff sets forth different rates, depending on the size of the solar panel system.  For those under 20 kilowatts (which should include most residential solar installations), the utility will pay 21.8 cents per kilowatt-hour (kWh).

  Hawaii is an expensive place to live – it has the highest electricity rates in the county, by a long shot!

  According to the U.S. Energy Information Administration, the state’s average electricity rate in 2009 was 21.21 cents per kilowatt-hour, compared to 18.06 cents per kilowatt-hour for second-place Connecticut. However, residential rates reached an average as high as 24.20 cents per kilowatt-hours, compared to 20.33 cents per kilowatt-hour in Connecticut.

  For people that live in Hawaii, options for electricity are limited – unless you go with solar power!  Most of the power generated in the state comes from power plants running on petroleum.  With high oil costs, utility bills are even higher.

  With the feed-in tariff, people in Hawaii can benefit greatly from installing solar panels.  Not only does the program help defray costs, but federal, state and local incentives and rebates further diminish the cost of going solar.

  Funding from Sunshot Solar Rooftop Challenge Awarded to Chicago

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  Solar grants from the U.S. federal government help move residents and businesses away from fossil fuels toward a brighter, cleaner future.  The Department of Energy recently approved significant funding from the Sunshot Solar Rooftop Challenge to the City of Chicago.  The $750,000 grant is one of the largest to date, and is dedicated to support streamlining the zoning, permitting, interconnection and inspection processes for residential solar systems.

  

  Rooftop solar challenge

  The funding from Sunshot Solar Rooftop Challenge awarded to Chicago will help make it easier for people to go solar because the regulatory red tape will be lessened via the program to be funded by the grant, according to Mayor Rahm Emmanuel.

  With less process and approvals required, both applicants and utility companies will be able to push through proposed rooftop solar panels connected to the grid in a more cost effective, efficient manner.

  Here is how the program is projected to work, in a summary fashion:

  Sunshot solar addresses the inefficient factors of the various governmental entities that regulate the electric grid.  By combining several steps required to feed solar power generated from solar panels into the grid, savings quickly add up via the reduction of administrative fees that can sometimes climb to a few thousand dollars.

  Chicago is not the only city or region that can benefit as a result of funding from the Sunshot solar rooftop challenge.  Any area in which bureaucracy adds up to unnecessary, duplicative fees and charges can encourage more solar installations through a reduction in red tape and required paperwork.

  If you live in a city or region that could benefit from solar but are fighting clogged permitting and/or installation fees, please add to the comments below.  You might be ready for DOE federal funding to make going solar easier!

  Solar Power Market Predicted to Grow in 2012

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  No matter the economy, tax credits/incentives or greenhouse gas emissions and global climate change, there are many factors that could – and do- influence the solar power market.  No matter what people say about Solyndra or any other renewable energy company, the solar power market is predicted to grow in 2012.

  

  Solar Power Market to Grow in 2012

  Last month, Solarbuzz, one of the most prominent solar industry research groups, released its 2011 third quarter report for the North American PV Markets.  The report shows that, despite several setbacks this year, the solar power market grew at an impressive rate – 101% over 2010, to be precise!  That translates into a 1.9 gigawatt increase, nearly doubling solar power capacity.  According to Solarbuzz:

  With 811 megawatts of new solar installations projected for the fourth quarter, the North American solar market should grow 32 percent from the third quarter of 2011. According to the Solar Energy Industries Association, the U.S. as a whole added slightly more than 878 megawatts of solar installations in 2010, only 67 megawatts more than the region will add this quarter.

  The growth in the solar power market is primarily for residential solar installations, but rooftop solar is increasingly being installed by businesses looking to trim operational costs.

  Selling a Solar Powered House

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  

  Selling a solar powered house

  Home solar panels are becoming more popular as people tap into generous tax incentives and rebates, and also look to trim utility bills over time.  But did you know that selling a solar powered house is easier (all things being equal) than one without solar panels?  Not only can you sell more quickly, but often for more money when you have a solar panels on your home.

  There are a few reasons for this.

  First, people are looking for some security against rising electricity costs.  Each year, you run the risk of your utility raising rates, but solar power generated by panels on your home only gets cheaper over time as you re-gain your return on investment.  The power is free!  Second, home buyers realize that average electricity use is increasing via appliances (yes, even energy saving ones), running air conditioning and heating, and even plugging in electric cars!

  While the initial outlay of funds for home solar panels generally ranges from $10-20,000, after tax credits and incentives, most homeowners save about $150 each month in electricity bills.  When selling a solar powered house, buyers realize that they are investing in more than just the real estate – they are purchasing “free power,” and security against rising costs down the road.

  Estimates are that, for every $1 you save in annual electricity costs, the value of a home increases $20.  With savings of $150 x 12 months ($1,800 annually), you can realize a $36,000 instant boost in equity.  Selling a solar powered house is generally quicker with a higher return than the same home without solar panels.

  Solar Power to Pass Fossil Fuels in Investments

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  While we might not quite be at grid parity for solar power compared to other energy sources, when it comes to investments, solar power is passing other resources at an impressive pace.

  

  Solar power is an impressive renewable energy resource

  Calculations by Bloomberg New Energy Finance show that investments in renewable energy are surpassing fossil fuels for the first time in new power plant investments. Consider this: electricity from the wind, sun, waves and biomass drew $187 billion last year compared with $157 billion for natural gas, oil and coal.  All this results in lower materials and equipment costs.

  Last week, Bloomberg New Energy Finance reported that renewable energy investments, like those in solar power, are projected to double over the next eight years and reach $395 billion per year.  While it is not yet enough to stabilize emissions and control climate change, it is still a step in the right direction.

  What do you think about solar power passing fossil fuels in investments?

  Solar charging canopies for electric vehicles

  With more and more companies producing electric cars, and consumers looking to buy emissions-free vehicles that can save them significant money at the pump, is it any surprise that solar charging canopies are gaining in prominence?

  Using solar power to charge electric vehicles (EVs) is becoming more common-place both at residential and commercial sites.  General Motors has pursuing more eco-friendly electric vehicles including as the Chevrolet Volt. Now, new solar charging canopies, including the Tracking Solar T have been installed at GM’s Company Vehicle Operations site in Warren, Michigan.

  Envision Solar has developed the Tracking Solar Tree, which generates additional solar power by following the course of the sun as it crosses the sky each day.  The hybrid multi-axis tracking design increases renewable energy production by 25% compared to traditional solar panels. The Solar Tree can produce up to 30,000 kilowatt hours over a year, which is enough solar energy to charge six electric vehicles per day.

  Rob Threlkeld, GM global manager of renewable energy said:

  “We are constantly looking for places where we can add a renewable focus. This solar tree is an ideal addition because not only does it provide a space to charge our electric vehicles, but it’s another step in our journey toward cleaner energy use.”

  Desmond Wheatley, President and CEO of Envision Solar also stated:

  “Our Solar Tree structures can be installed in any location while our unique tracking solution allows us to always get the most from the sun. As such they are the perfect visible embodiment of GM and its dealerships commitment to the environment and the future of electric and other highly efficient vehicles. We look forward to installing many more of our iconic tracking Solar Tree structures for GM in the coming months.”

  When it comes to electric vehicles, what do you think about these solar charging canopies?

  Solar Rebates and Tax Incentives Will Not Last Forever

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  

  Solar rebates and solar tax incentives

  The exact measure of the benefits of solar rebates and tax incentives is a subject of debate.  Some question whether the government should allow tax revenues to be trimmed with rebates, given the current economic climate.  Others believe that the free market should be allowed to operate, and if people cannot afford solar power, they shouldn’t make the switch.

  Personally, I am of the mind that solar rebates and tax incentives are important to encourage property owners to forgo cheaper sources of electricity (coal) in favor of renewable energy.  As grid parity – the point at which solar is as inexpensive as coal - comes closer and closer, the need for incentives will diminish.

  Since the federal tax credit became available in 2006, solar panel installations have increased 800%.  Some of the growth is attributed to falling solar panel costs, but many agree that incentive programs have allowed many people to successfully switch to solar power.

  State and local solar incentives vary, depending on where you live.  But the federal tax credit incentive covers as much as 30% of the cost of solar photovoltaic (PV) panels is available across the nation.  Under pressure to reduce the national debt, lawmakers have set the solar tax credit system to expire at the end of 2016.

  The solar tax incentives could end even earlier than 2016, if Republicans make significant gains in the upcoming 2012 elections.

  Either way, solar rebates and tax incentives will not last forever.  At least not until more lawmakers recognize the importance of continuing to encourage growth in the solar industry.  In the meantime, if you are considering installing solar, now may be the time to do so!

  Solar Christmas Lights: Five Reasons to Unplug This Season

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  

  Solar Christmas lights

  Its time to decorate for the holidays!

  This year, when choosing your lighting options, why not install solar Christmas lights?

  Here are five reasons to unplug this season with solar powered holiday lights:

  1.   No need to find a convenient outlet.  Solar Christmas lights use energy from sunlight, instead of grid-based electricity.  During the day, solar panels absorb UV light and, at dusk, your solar lights automatically come on, running on solar power for up to 8 hours.  Decorate fences, mailboxes, and property boundary trees and shrubs without dangerous extension cords or trenching and wiring.

  2.   Enjoy your Christmas lights all night without worrying about your electricity bill.  Because solar powered holiday lights don’t require electricity, you won’t be hit with a giant power bill in January.  Let’s face it – you will probably be paying extra in other bills after the season.  The last thing you need is to give your utility a holiday bonus!

  3.  LED lights are brighter, safer, and last longer than incandescent bulbs.  Solar powered light bulbs burn cool to the touch, making them a safe lighting option.  Solar LED lights are also brighter and last longer than their traditional counterparts.   This means you don’t have to replace them as often, either, saving you even more money!

  4.  Solar powered Christmas lights are available everywhere.  You don’t have to go to a specialty store, or spend a lot of money online to find solar holiday lights.  Just about every retailer that sells Christmas decorations now carries solar lighting, as well.

  5.  Give a gift back to the environment.  The holiday season is one of excess.  Why not give a little back to Mother Nature?  Unplug your Christmas lights this year and go solar!

  Occupy rooftops on Community Solar Day

  Let’s raise awareness of the positive impact of solar power.  Band together with your neighbors and friends on November 20, 2011 for the first Community Solar Day: Occupy Rooftops, organized by Solar Mosaic, 350.org, Vote Solar, and others.

  The day is dedicating to gathering people around the world in support of solar energy.  Participants will “occupy rooftops” by gathering at a building that would benefit from rooftop solar panels, both to save energy and create local green jobs.

  Community Solar Day will work as follows:

  1.  Locate a building in your hometown that would benefit from rooftop solar panels.

  2.  Gather a group of friends, neighbors and others in your community to come out and support solar power

  3.  Visit the building on which solar panels would be ideal and take a photograph in front of  your dream community solar project.

  4.  Post your photograph on meetup.com/Community-Solar.

  Community Solar Day is intended to be more than just an opportunity to post photographs.  We need to convince property owners and government leaders that solar power and other renewable energy projects benefit our community by saving money, increasing energy security and breaking free from our reliance on finite fossil fuels.

  If you are interested in participating in Community Solar Day, visit Vote Solar for a primer on community solar and a policy toolkit. Learn more and sign up here.

  Group Discounts for Solar Power

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  Is it any wonder that sites like Groupon are so successful?  Get a bunch of people buying the same thing at about the same time, and you can reduce the cost of the item, benefiting everyone – including the seller, who makes more sales.

  

  Group discounts for solar power?

  Group discounts for solar power, offered through companies like One Block Off the Grid, are an especially smart move for a number of reasons.  First, the cost of solar panels is often off-putting to homeowners.  Second, the idea that other people in your neighborhood or region also are installing solar panels may give you an idea of community, or belonging, especially where some people still regard solar power as a “fringe” idea.

  Dave Llorens, founder of 1BOG, comments:

  “The idea was to put this online and deliver it to thousands of people at a time.  No one wants to have a salesman in their living room, they just want the numbers.”

  In order to obtain group discounts for solar power for its potential customers, One Block Off the Grid screens solar contractors in regions that already offer solar subsidies.  The company then works with approved contractors to get them to offer a percentage discount when and if 1BOG brings a large enough group of customers.  If a deal is reached, it is offered on the One Block Off the Grid website.  The only “catch” is that the estimated number of people must agree to buy the panels in order to get the deal.  Usually, people looking to buy solar panels can realize a discount of about 15% in addition to a $500 rebate.

  The cost of solar panels is usually much less using group discounts.  Mr. Llorens states that 1BOG only offers deals with a return on investment (ROI)  of 10 years or less.

  Financing Solar Installations for Schools

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  The United States Department of Energy (DOE) released a report last month with information on financing solar installations for schools.  The report, titled “Solar Schools Assessment and Implementation Project: Financing Options for Solar Installations on K-12 Schools,” was published on October 20, 2011.

  

  Solar panel installations on schools

  The report was produced under the DOE’s SunShot initiative to support development of Solar Master Plans for three California public school districts: Oakland, Berkeley, and West Contra Costa Unified School Districts.  According to the Department of Energy’s website:

  The SunShot Initiative is a collaborative national effort to reduce the cost of solar energy by 75%, making it cost competitive with other forms of energy by the end of the decade. The new study supports DOE’s SunShot Initiative goal of addressing critical barriers, such as the availability of financing, to accelerate the integration of solar energy technologies across the United States. Installing solar energy systems on public schools can help school districts save money on their utility bills, reduce carbon emissions, support job creation, and provide students with opportunities to learn about clean energy.

  At a time when school districts are looking to save energy in order to save money, and perhaps teach students a lesson on renewable energy, solar installations for schools makes great sense:

  The DOE report compares and contrasts the two primary options for financing solar: (1) direct ownership, whereby the school takes out a loan to purchase solar panels, and (2) solar power purchase agreements or solar leasing, under which a third party owns, operates and maintains the solar panels and sells solar electricity generated by the array to the school at a cost less than typical grid-based power.  The third-party finance model also includes Energy Saving Performance Contracts, in which cost savings from energy efficiency improvements help to pay for the solar installation.

  The analysis in the report is intended to help administrators select the best option for financing solar installations for schools.

  For more information, see the DOE Progress Alert, the complete report, and the SunShot Initiative website.

  Solar Garden Gifts

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  I am a big fan of solar garden lights.  They are easy to install because they require no trenching or wiring, let alone electricity.  Line your pathway, patio, deck or more for beautiful evening ambiance and safety.

  

  Solar turtle light

  Beyond lighting, we have found some cool solar garden gifts that are decorative and eco-friendly:

  Solar Turtle Light:

  When the sun goes down, this cute garden turtle’s shell glows amber, using solar power absorbed during the day from a small solar panel.  During the day, the garden critter looks just as adorable while the batteries in his shell are recharged by sunlight.

  You can find the solar turtle light at Bits and Pieces for $29.99.

  Tiffany Style Outdoor Solar Light:

  Like other “ordinary” outdoor solar lights, this Tiffany-Style light is outfitted with solar panels.  Ultraviolet light recharges an internal battery during the day, then at dusk, an internal sensor activates the solar powered light inside.  The Tiffany Style light resembles stained glass and is more expensive than ordinary solar garden lights.  However, we recommend you get one or two to use as an accent in the corner of a planting bed, or on a deck or entryway.  At the Home Shopping Network, the light is $69.95.

  Solar Fireflies:

  If you enjoy watching fireflies flickering in the summer evening, you can now have your own firefly display any time of year.  The solar fireflies can be placed in your favorite shrub, and they automatically visit your garden each evening – just like the real thing!

  A solar panel is positioned to absorb UV light during the day, and at night, the fireflies flash, flicker and fade to your delight.  You can purchase a package of 7 or 14 solar fireflies at Firefly Magic Firefly Lights, for $67.95 or $87.95, respectively.

  

  Solar Powered Flamingo

  Solar-Powered Flamingo:

  This has got to be my favorite solar garden gift.

  The ubiquitous garden pink flamingo now glows bright at night, thanks to solar power.  Simply insert the flamingo into the ground and a small solar panel absorbs sunlight during the day.  At night the solar-powered flamingo lights up!

  Its also available at Bits and Pieces for $34.99.

  Solar garden gifts are perfect for birthdays, anniversaries, Christmas, or any other special time of year.

  Things That Affect How Well Solar Panels Work

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  Solar power is a clean, renewable source of energy and is becoming so affordable that it is reaching grid parity with coal and natural gas.  But before you decide whether solar is for you, consider the things that affect how well solar panels work.

  Surprisingly, where you live has little to do with solar panel efficiency.  The primary impacts on solar output are from shading.  Solar panels that are shaded by trees, other vegetation or adjacent buildings are generally less able to produce electricity than those that are not shaded.  Even shade on a single panel can affect the overall performance of a solar array.  We recommend that you have a solar professional examine your property before purchasing or leasing solar panels to determine if and where solar panels should be located.

  

  How solar panels work

  Other components of a solar array can also affect the production of solar electricity.  Solar inverters convert the direct current that strikes a panel surface into alternating current, which is the power you tap via an electrical outlet.  The angle at which your panels are installed, and their placement on your rooftop, can also help maximize the amount of sunlight that hits the panels.

  Improving overall energy efficiency within your home or building will help you save even more money with solar panels.  While solar electricity is free, there are limits to the amount that can be generated by a distributed generation system.  If you use more energy than you produce, you’ll draw on the grid (with a grid-tied system), increasing your power bill.

  You can generate solar power even on a cloudy day because UV light is the primary factor required.  However, snow and ice can block sunlight from the solar panels, reducing their efficiency.  There are ways to remove snow on solar panels.  Other than that, minimal maintenance is required for a solar array over its lifetime.

  In short, the things that affect how well solar panels work are largely within your control!

  Best Sites for Solar Power Projects in the Western United States

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  The U.S. Bureau of Land Management (BLM), a part of the Department of the Interior, has identified the best sites for solar power projects in the Western United States.  A new plan unveiled by the Obama administration identifies seventeen “solar energy zones” in six states west of the Mississippi in which utility scale solar power plants should be considered.

  

  Siting solar power projects on U.S. desert lands

  Nearly 450 square miles (285,000 acres) of desert lands in Arizona, California, Colorado, Nevada, New Mexico and Utah have been given high priority for solar development.  According to a report in the Los Angeles Times, identifying solar energy zones is “intended to make some of the desert’s most sensitive landscapes less desirable for solar prospecting by identifying ‘sweet spots’ that have already passed environmental requirements and therefore promise expedited permitting.”  An additional 31,250 square miles in the region were also identified by BLM as potential sites for solar power projects, provided environmental impacts could be minimized.

  Both environmentalists and solar developers praise the BLM solar energy zone policy.  Streamlining solar permitting will benefit utility scale projects, while location of such projects in areas that are not constrained by environmental or cultural conflicts.  The policy, however, will not affect the continued permitting process and construction of 13 solar power projects in the Mojave Desert region.

  Solar Power Creating New Green Jobs

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  With the economy struggling to recover, its always great to read hopeful, positive news like this.  Solar power is creating new green jobs at an impressive rate in the U.S.  According to the Solar Foundation, there are now over 100,000 Americans that are employed in the solar industry, based on preliminary data from National Solar Jobs Census 2011: A Review of the U.S. Solar Workforce.

  Solar power is becoming more widespread and affordable, which continues to increase demand for employees.

  

  Solar jobs increasing in the U.S.

  Over a 12-month period from August 2010, approximately 6,735 new solar employees were added to the workforce, which is a growth rate of 6.8%, according to the National Solar Jobs Census 2011.  Employment within the solar industry in the U.S. has grown at a rate that exceeds that of fossil-fuel based electricity generation, as well as the overall economy (which grew by only 0.7%) during the same period.

  According to Andrea Luecke, executive director of The Solar Foundation:

  “The U.S. solar industry is creating jobs at a far greater pace than the economy as a whole.  The National Solar Jobs Census series provides a definitive measure of the U.S. solar workforce and its growth over time. It proves where smart solar energy policies are having the most impact both in terms of states and across the vast solar supply chain.”

  To read more about solar jobs and the growth of this industry, review the full National Solar Jobs Census 2011 report, which was made available on October 17 this year.  Figures for solar employment in various fields, including installation, wholesale trade, manufacturing, utilities and more are included, as well as growth rates and job numbers.  Solar power green jobs are also reviewed at the state level.

  Top Five Countries for Solar Power

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  Over the past three years of this blog, we’ve covered many of the countries that have encouraged solar power via tax rebates and other government incentives.  Of the top five countries for solar power, several lead from the standpoint of technology and research and development.  Others have vast solar resources due to weather or their longitude/latitude position on the globe.

  In these five countries, reliance on solar power is increasing with construction of utility-scale solar power plants and more.

  

  Utility scale solar power

  Let’s review the top five countries for solar power and what makes them among the leaders worldwide.

  1. Germany

  For several years now, Germany has topped the list as the best country for solar power, thanks in large part to supportive pricing which led to the addition of a number of high capacity solar energy power plants.  Government incentives and public interest in solar have also encouraged R&D, leading to advances in thin cell solar technology and improvements in solar cell equipment.

  2. Spain

  Spain ranks number 2 as a top country for solar power production.  The country’s government mandated feed-in-tariff pricing in 2007, which resulted in a rapid increase in solar cell development of over five-fold in a single year!  Spain’s climate makes it an ideal place for solar energy power plants.

  3. Japan

  In Japan, research and development is leading to new solar technology at an amazing pace, as the country hosts a number of bright and talented scientists and researchers.  Japan’s solar research will help increase the efficiency of solar cells, so that the maximum amount of solar energy can be tapped from sunlight.  The country is also aiming to increase solar power plant capacity from 10% to 40% with the help of government incentives and assistance over the next decade.

  4. United States

  The United States is a top country for solar power for several reasons: solar technology, research and development, and utility scale solar power plants (concentrating solar power).  Several states have adopted programs to encourage installation of solar panels, including New Jersey and California.  Much of the climate in the U.S. is favorable for the production of solar energy.

  5. China

  China has come on strong in the solar power world in recent months.  Like other top countries for solar power, China is a leader both for solar technology and development, as well as number of solar energy power plants.  China produces the most solar hot water in the world and accounts for 2/3 of global solar electricity production.  The country is now the world leader in solar PV panel production.

  Solar Ship

  What if blimps or other aircraft could move through the skies without using polluting energy?  Solar Ship (pictured to the left) has a minimal carbon footprint, using solar energy to power the helium-filled aircraft.

  Using solar power, Solar Ship can move through the sky, carrying 2,250 pounds of payload for 1,000 kilometers (621.4 miles).  The company has both solar and hybrid models.  The 100% solar ship Caracal can carry about 330 pounds, while the huge Nanuq can carry 30 metric tons, or an impressive 66,139 pounds!

  The Canadian firm envisions its solar ship machines helping with tasks from hauling humanitarian relief to moving payloads for mining operations in remote locations.

  Public demonstration of the solar ship aircraft will occur sometime in the summer of 2013. However, you can get a preview of the company’s aeronautical vision below:

  Solar Leasing Preferred Over Cash Purchases in California

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  

  Solar leasing saves money

  In California, solar leasing is preferred over cash purchases.  That means that property owners are looking for less expensive ways to switch to solar power, without the initial down payment and investment.

  Solar panel leases offered by companies like SunRun allow people to enjoy the cost savings and other benefits of solar electricity without purchasing, owning or maintaining a solar array.  Through a solar lease, property owners purchase the power generated by panels installed, owned and maintained by a solar company, at a lower monthly cost than electric utility bills.

  As announced by SunRun and PV Solar Report, third-party-owned solar eclipsed cash purchase as the preferred way to go solar in California, representing about 59 percent of California’s home solar market in the third quarter of 201, and 51 percent of the market year to date.

  According to SunRun President Lynn Jurich:

  “In 2007 we introduced a way for homeowners to put solar panels on their roofs without having to spend $35,000 to buy and maintain the equipment.  Families love it because they can lock in low rates for clean energy and start saving money right away.  It’s great to see it finally get to a point where more families know this service is available, and to see them choose it over other options.”

  While solar growth has increased in 2011, statistics in the PV Solar Report show that 3rd-party-owned solar grew by 67% in the third quarter of 2011, generating an additional $157 million in growth for the state of California.  The increase in solar cash purchases was only about 17%.

  SunRun’s solar lease program for residential solar was created in 2007 and grew at about 200%  in 2010.  Stephen Torres, founder and managing director of PV Solar Report comments:

  “The message is clear that California homeowners are adopting 3rd-party-owned systems because access to solar power is better than ownership of panels.  Business models like SunRun’s are not only allowing families to switch to solar without the high upfront cost of a cash purchase, but also helping local economies increase revenue and create jobs.  We’re excited to see the growth trend continue.”

  Solar Power at Frito-Lay

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  More and more, corporations are turning to renewable energy to both save money and improve their overall carbon footprint.  Turns out that going green is a good business decision for a number of reasons.  Consumers want to purchase products from environmentally-sensitive businesses, which means that solar power is being installed at a rapid rate these days.

  

  Solar power at Frito-Lay

  Solar power at Frito-Lay is one of the latest developments in this trend.  The company – a subsidary of PepsiCo -  produces popular snacks, including SunChips, Doritos, Lay’s, Cheetos and Fritos.  In Casa Grande, Arizona, its near net-zero facility includes five solar installations.  Solar power facilities include ground-mount arrays with trackers to follow the sun across the sky.

  Some of the panels are owned by Frito-Lay, while others are owned and operated by Arizona Public Service, which sells the clean solar electricity to the corporation via a solar power purchase agreement.

  In addition to getting most of its electricity from solar, the company also made some significant sustainability achievements. Natural gas consumption is reduced 80%, and Frito-Lay is recycling 75% of water used onsite.  Overall, the company has reduced its greenhouse gas emissions by 50%, with a tiny fraction of only 1% of waste produced at the plant sent to landfills.

  The solar power and other green energy revisions at Frito-Lay’s Casa Grande plant will serve as a model for other facilities around the world.  Overall, the company hopes to achieve near net zero across its plants, and cut down on its carbon footprint by becoming more eco-friendly.

  Dow’s Solar Shingles Available for Homeowners

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  For the past several years, we’ve been blogging about rooftop solar shingles.  As an alternative to bulky PV panels, solar power shingles blend in, while generating cheap solar power.  Its a perfect example of building integrated photovoltaics.

  

  Dow's solar shingles are available for homeowners

  Finally this month – October 2011 – Dow Corning’s Powerhouse Solar Shingles are finally available for homeowners.  The company’s catch phrase is:

  “Our Solar Shingles aren’t on the roof, they are the roof.”

  If your home improvement list includes re-shingling the roof, perhaps you should consider Dow’s solar shingles to generate clean and green renewable energy.  The solar shingles will be available this month in Colorado, and then rolled out to California and other targeted states throughout the coming year.  Constructed with glass-free, thin-film, building-integrated photovoltaics, the solar shingles are like conventional roofing shingles in almost every regard.

  Dow’s solar shingles are durable and simple to install and use.  While there are a number of benefits, the only drawback is that consumers are still awaiting a final estimate on solar shingles’ price.  However, Dow Solar Vice President Jane Palmieri commented that their solar shingle systems may cost cost up to 15 percent less than conventional solar panel arrays.

  With federal, state and local solar tax credits, solar shingle projects are probably more affordable than you’d think.  Ranging from $8,000-15,000, these systems can generate half (or more) of a home’s power requirements.  Not only that, but if you pay for regular roofing materials, as well as solar panels, you’ll invest thousands more than with Dow’s solar shingles.  The specialized shingles last as long – if not longer- than regular asphalt shingles.

  What do you think about Dow’s solar shingles?  Will they change your mind about switching to solar power?

  Personal Electricity System Uses Solar Energy and Mobile Phone Technology

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  

  What if you could tap into a personal electricity system that uses solar energy and mobile phone technology, rather than grid-based power?  Recently, a UK company called Eight19 announced a solution called IndiGo, which is a pay-as-you-go, personal electricity system for the developing world.  Combining solar power and mobile phone technology subscribers can light their homes and charge mobile phones using scratchcards.

  Using solar energy, Eight19 believes it can increase access to electricity for over 1 billion people who are not connected to the grid.  The project will not only help improve the lives of Third World residents by bringing light and refrigeration to the villages, but it also helps minimize the negative impacts of living with kerosene – both via the fumes and expense.

  

  Eight19 solar film

  Steve Andrews, CEO of Solar Aid, commented:

  “We are excited to be working with Eight19 on this revolutionary technology. Solar energy offers huge economic, health and social benefits to the world’s poorest people; for lighting and mobile phone charging. Eight19’s technology opens up these benefits to many more people. This is a major breakthrough”, said Steve Andrews, CEO of Solar Aid, a charity supporting product trials in Kenya.

  Its easy to switch to solar power with the IndiGo system.  Components include a low-cost solar panel, a battery unit with inbuilt mobile phone charger and a high efficiency light emitting diode (LED) lamp. Users can put credit on their IndiGo device using a scratchcard, validated over SMS using a standard mobile phone.

  Watch for overall commercial roll-out of IndiGo in early 2012.

  Simon Bransfeild-Garth, the CEO of Eight19 comments:

  “We are very encouraged by this new way of delivering energy to off-grid applications in emerging markets.  Indigo enables a new generation of solar power products that are affordable, providing customers with access, often for the first time, to clean low cost energy that eliminates the health risks and carbon emissions of kerosene.”

  Compare Solar Panels for Installation

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  If you are thinking about installing solar panels on your home or business,  you should compare the different makes and models available.  Much like buying a car, the investment in a solar power system is not one that is undertaken lightly.

  

  Before you install solar panels, consider these factors

  It is very helpful to hire a knowledgeable solar panel installer.  But, to avoid paying extra for things you may not need, here’s how to compare solar panels for installation.

  When you do a search for residential solar panels on the Internet, there are several factors that help you compare solar panels: (1) cost; (2) efficiency;  (3) amount of energy conserved; and (4) the estimated life of the solar power system.

  Cost is directly related to solar panel efficiency.  The more efficient (i.e., the more sunlight a panel can convert) the less expensive relying on solar power will be.  As of the date of this posting, the average solar panel efficiency is between 13-18%.  That means that solar panels result may result in more cost savings than solar thermal installations.  Don’t forget to think about the annual decline in solar panel efficiency, which is often represented in panel warranties.

  PV (photovoltaic) solar panels are pretty much the norm for residential and small business installations.   Solar technology is continuing to improve for these products.  As noted in a related post:

  Polycrystalline cells are cheaper to produce, but since they require connecting numerous silicon cells, are less efficient in converting sunlight to electricity than a single crystalline cell. Visually, it’s usually easy to tell them apart. With the exception of Sharp, SolarWorld and Trina brands, monocrystalline panels are black, while polycrystalline panels are blue.

  Comparing “cost per PTC” figures is the best way to determine which solar panel offers the most efficiency at the best price. Keep in mind that each solar panel costs about $400-700, and the cost-per-PTC prices ranges from $2.50 to $4.50.  Once you determine the number of solar panels needed, its easier to compare costs for installation.

  Don’t forget that there are a lot of solar companies that install panels these days.  You don’t have to do with the first name you read.  Make sure that your solar contractor knows your area and other options.

  Solar Panel Efficiency: How Does it Measure Up Over Time?

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  Most consumers know that an investment in solar power will last 25-30 years.  For this reason, the return on investment is important to consider if you are planning to sell your home within a few years of installing solar.  Another important consideration is solar panel efficiency.  Like any other home improvement, you can expect some minor decline in performance over time.

  

  What is the expected performance of solar panels?

  The performance of solar panels is pretty consistent over the decades they are expected to last, however.  Solar panel manufacturers and the solar industry in general expect the greatest decline in the first year: approximately 2-3%.  After that, a very small degradation rates of half a percent (0.5%) each year may occur.

  Warranty information provided by solar manufacturers is helpful information to assess solar panel efficiency.  Solar output warranties use an industry standard of 90% output in the 10th year of usage.  By the 25th year, solar manufacturers guarantee at least 80% solar panel efficiency.

  Warranties and guarantees, of course, are more conservative than the actual performance of solar panels.  Manufacturers are using a “worst case scenario” in predicting solar output declines over the years.

  Actual solar panel efficiency of the installations on your property could be much higher.  Consider the fact that very little (if any) maintenance of solar panels is required.  This is because the panels do not include any moving parts, and they have been designed to withstand extreme weather conditions.

  This means that an investment in solar power is probably even more sound than you’ll read in warranty information!

  Install Solar: Earn Money

  Tags:    [edit]

  

  Install solar and save money?

  Think solar power is too expensive?  Maybe you don’t know what you’re missing.  Not only can you save energy and save money, but some homeowners are actually earning money after installing solar.

  Grid-tied solar using smart metering can actually turn your utility meter backward.  When your solar panels generate more electricity than you use, you might even get a check from your utility at the end of the month if you have net metering, rather than sending them a payment!

  The fact that you can actually earn money with solar installations is not well-known among homeowners.  But some people are starting to share their stories to help spread the word.  As part of the National Solar Home Tour, several property owners will be available to  answer questions about the Solar Renewable Energy Credit (SREC) program.

  Here’s an overview of how it works.  For every megawatt hour of solar energy production, homeowners earn one SREC credit.  The reason why you get the credit is because utilities are legally required to invest in renewable energy. They can meet requirements by purchasing excess power generated by residential solar.  Homeowners can sell this power directly to the utilities or on an open market.

  The price for SREC credits varies, depending on where you live.  Generally, they range from $200-$700.  In fact, some states require utilities to purchase excess energy generated via net metering at the same rate as that charged for conventional grid-based power.

  How can you install solar power and save money?  The average home solar power system costs between $10-20,000 after credits and tax incentives.   Homeowners can recoup the cost within a decade or less.  After that, your entire SREC is money in your pocket.

  Consider that solar PV power systems have a life of 20-30 years, and you will have 10-20 years of additional income generated by solar panels!

  Solar Installation Gold Rush?

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  

  With solar tax credits unknown, will people choose not to take a risk on the investment?

  Recently, I read an article on cleanenergyauthority.com that described the recent upswing of interest in residential solar power as a “gold rush.”

  To be fair, the article was commenting on a report published by Photon Consulting, titled “End of the Gold Rush: Crash of U.S. SREC Markets?”  There, the commentators opined that, as the solar renewable energy credits that fueled solar energy growth dry up, we could see market crashes in the solar industry, which would result in losses to homeowners and businesses who installed solar panels in the past few years.

  Several states will be most affected, according to the report:

  “[The credits] have created a gold rush of solar installations in U.S. states like Massachusetts, Ohio, Maryland, Pennsylvania and New Jersey. However, these self-correcting incentive programs may significantly dash future market growth expectations.”

  The study’s authors commented that the report is not meant to scare consumers, but merely to provide a tool to examine future markets in solar power, particularly systems that have been constructed with solar renewable energy credits (SREC).  The issue is not that SRECs may be reduced or eliminated, but the uncertainty surrounding the credits in the future.  As a result, market and pricing estimations for solar panels are unpredictable, leaving some unwilling to take the risk.

  In general, Renewable Energy Portfolio standards, require utilities to obtain a certain percentage of their power from renewable sources.  These standards have both driven demand for clean energy and the credit programs for continued growth. The problem is that the supply of renewable energy is catching up to demand, and the purpose for the credits – and the credits themselves – are slipping away.

  In some states, like new Jersey, the change in SREC is already having an affect on solar power demand.  However, before you change your mind about renewable energy systems for your home or business, keep in mind that there are a lot of factors in play which could actually result in another increase in SRECs and associated demand for solar.

  In short, investing in solar power is much like investing in the stock market.  There are no guarantees, and factors over which you have no control could dramatically increase or decrease the value of your investment.

  Keep in mind, however, that reduction of CO2 emissions with solar installations is a long-term investment that will benefit the planet as a whole, including your family and future generations!

  Solar Shingles: Cost-Effective for Residential Solar?

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  Over the past few years, we have written several articles about solar shingles – roofing material that both covers your home with a protective layer and generates clean, renewable solar power.  As with other types of solar panels, one of the biggest questions regarding solar shingles is whether they are cost-effective for residential solar?

  

  Installation of solar shingles

  Also known as solar roof tiles, solar roofing shingles, solar shingles originated as the brainchild of Dow Chemical in 2009.  The company announced that it had come up with solar technology that could be included as part of asphalt tile roofing material for homes.  Dow and Global Solar would be manufacturing solar shingles together.

  The tiles are a premier example of building integrated photovoltaics – or building materials that can generate solar power.  Last year, Cobblestone Homes installed solar shingles on its new homes to help test the product.  After a successful trial run, Dow is  building a manufacturing facility in Michigan that will begin production of Dow Powerhouse Solar Shingles in 2012.

  Consider these benefit of solar shingles:

  • Installed just as regular asphalt roofing shingles
  • Waterproof, glass-free and encased in UV-stabilized polymers, solar shingles are practically virtually indestructible.
  • They can be dropped from a roof, walked on and stacked in pallets like any other type of roofing shingle
  • Connections are simpler than for ordinary solar panels because solar shingles plug into each other to form a solar array

  With respect to whether solar shingles are cost-effective for residential solar, one of the most influential factors is solar efficiency.  Reportedly, solar shingles are only 10% efficient (meaning that 10% of the solar energy that strikes the surface can be converted to solar electricity), while solar panels are 13% efficient.  In addition, the cost of solar roofing is about 10-15% more than ordinary PV panels.

  The actual price of Dow’s solar shingles is not known as of the date of this publication.  Yet, some experts are predicting a cost of about $50 per square foot, with an output of 600 watts for every 100 square feet.

  Homeowners can take heart in the fact that solar shingles, like ordinary solar panels can qualify for tax incentives and rebates that can defray the cost an additional 30-50%.  One estimate is that a solar shingle system for an average homeowner in Michigan will cost about $11,200, including rebates.

  Solar shingles will soon be available for homeowners across the U.S.  Stay tuned for more information on pricing and other factors.

  Solar Technology: Transcluscent Solar Cells

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  

  Transluscent solar cells

  Solar technology and research continues to help find more efficient and less expensive ways of generating solar electricity.

  One option may be transluscent solar cells (transparent).  Solar panels made using this solar technology, which consists of translucent crystal like cell with transparent backside, are now available for consumer purchase.

  Switching to solar power via transluscent solar cells will help you save money in a number of ways.  First, it is only an initial cost investment.  After you pay for the solar panels, you can enjoy free electricity thereafter.  From watching TV, running your refrigerator and heating water with solar energy, you don’t have to rely on grid-based electricity any longer.  This means that you can save money on your utility bills, as well as feel good about the fact that you are not relying on polluting coal-based electricity.

  On the downside, transluscent solar cells with this technology require consumers to buy fans and lights for the specialized solar panels.  The energy draw for these operations will reduce efficiency of the panels.  In addition, the upfront costs of switching to solar power are often cost-prohibitive.  You will also need back-up systems to store generated solar energy.

  What do you think about transluscent solar cells and solar technology in general?

  Tags:    [edit]

  

  The truth about solar power

  The debate may rage on about global warming and whether there is really a need for renewable energy.  Yet, the truth about solar power may convince some people that switching to solar is a wise choice, both from an economical and environmental standpoint.

  Consider these facts from 6 Truths About Solar Energy, an article that originally appeared in Green Chip Stocks. Green Chip Review is a free newsletter which is the first advisory to focus exclusively on investments in alternative and renewable energies.

  The reasons why solar power is an American success story include:

  1. The solar industry employs more than 100,000 Americans, more than twice as many as in 2009. they work at more than 5,000 companies, the vast majority being small businesses, in all 50 states.
  2. The U.S. solar industry grew by 69% in the past year, making it one of the fastest growing sectors in the U.S. economy.
  3. Since the beginning of 2010, the price of solar panels has dropped by 30%, and costs continue to fall making solar an even more viable choice for residential and business customers.
  4. The U.S. was a net exporter of solar products in 2010 by $2 billion. We were even a net exporter to China.
  5. Solar power in the U.S. now exceeds 3,100 megawatts. That’s enough to power more than 630,000 homes.
  6. Continued industry growth enhances our energy security and diversifies our domestic energy portfolio.

  Based on this information, there are very good reasons to back up solar power as a sound investment.  A number of experts are literally putting their money on solar energy as the next best bet in renewables.  As the costs continue to drop and efficiencies rise, solar power is positioned to exceed everyone’s expectations!

  Build a Solar Powered Car

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  For many of us, the idea of driving a car without having to fuel up at the gas pump is an ideal dream.  After all, fossil fuels are finite and who knows when the next gas price spike will occur?

  

  Learn how to build a solar powered car

  I recently read a post about a student at the University of Engineering and Technology Lahore in Pakistan who built a solar powered car in less than a month.

  Shown in the photograph to the left, the invention of Farrukh Kahn has been named “Solaron.”  Admittedly, this solar powered car is not your typical road-ready vehicle.  It has 3 wheels and was constructed with used bicycle parts and a 40 watt solar PV canopy that connects to an on-board 12 volt dry cell solar battery.  But for short trips, the solar car may be just the answer to get you to your destination without having to gas up, or emit CO2.

  This DIY solar project cost Khan less than $600 to construct.  The solar powered car has a range of about 43 miles and can reach up to 20 mph.  Admittedly, that is slow, but for local commutes and errands, it may be just the ticket to getting gas-free.

  Khan has posted complete instructions to assemble the solar powered car here.

  Solar battery charger

  Owning a solar powered battery charger can help you in an emergency, and also save money!

  Solar battery chargers are useful for vehicles (cars, motorcycles and boats) and will also work for battery powered generators, lawn equipment, garage door openers, electric gates and more.  Why?  Because things that run on solar power are not affected by grid outages.

  There is a wide range of solar chargers on the market, from foldable, portable solar power, to stand-alone photovoltaic (PV) panels.

  The smallest versions of solar powered battery chargers can be used for electronics including cell phones, mP3 players, cameras and computers.  Wattage varies, as well, depending on your power needs.

  Generally speaking, solar powered battery chargers that are 4 watts (up to 12 volts) or less are best suited for smaller batteries that do not take a great amount of time for recharging.  These solar chargers range in price from $25-100.

  The next level up are the 5-10 watt solar battery chargers.  They cost about $60-200, and can give a significant boost to batteries that have become drained.  These chargers are effective for electric gates and fences, and some industrial equipment.

  Solar powered battery chargers over 11 watts cost between $150 and $600.  Of course, they are best suited for larger batteries, including those for boats, generators, industrial use and more.  Simply place the panels outside in daylight and you’ll be able tap into solar power instead of grid based electricity or gasoline.

  Solar Power is Cost Competitive with Coal in Australia

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  

  Solar power is cost competitive with coal in Australia

  For years, people have discussed the concept of “grid parity,” which is the point at which generating solar energy does not cost any more money than burning coal or gas for electricity.

  In one corner of the world, it appears that grid parity is here.  Solar power is cost competitive with coal in Australia.

  The cost of solar has been dropping dramatically recently due to higher efficiencies and better solar technology.  People can now generate significantly more solar power at a lower price than they could a decade ago.  And, solar is more mainstream and accepted by property owners around the world and across the spectrum.

  So, what is special about Australia?

  On this island continent, photovoltaic (PV) panels installed on buildings and ground-mounted have resulted in a major dip in the cost of solar energy.  That means, that over a relatively short period of time, PV cells can now produce as much energy as coal, for about the same price.

  The precipitous drop in solar costs has lead to the ability for the renewable energy resource to rival coal-generated power.  According to the Australian Photovoltaic Association, grid parity is leading to reconsideration by government regarding solar panels and solar power as viable options.   This is so, even without subsidies for solar power.

  According to Photovoltaic Association spokeswoman Dr. Muriel Watt:

  “It’s competitive with coal if you add what you need to do to bring the coal-fired electricity to where you want to use it,” she says. “So it’s coal plus the network. I think it’s a really good investment . . .”

  Growth in the solar power market likely will mean a continuing decrease in solar production costs.

  With solar power cost competitive with coal in Australia, which continent/country will be next?  Can the USA soon reach the point when consumers will have a real choice between polluting fossil fuels and solar power for their electricity needs?

  How do Clouds Affect Solar Panels?

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  One of the biggest questions people have when they are considering solar power is, how do clouds affect solar panels?

  

  How do clouds affect solar panels?

  For a definitive answer, the National Renewable Energy Laboratory (“NREL”) recently published a study after extensive research on the effect of cloud cover on solar power installations.  NREL is a national laboratory that is part of the U.S. Department of Energy‘s Office of Science and is the only federal laboratory fully vested in the research, development, commercialization and deployment of renewable energy and energy efficiency technologies.

  The NREL’s study on how clouds affect solar panels is based on data collected over a year on the island of Oahu, Hawaii.  The purpose of its research is to determine where solar energy production may be compromised in a utility scale photovoltaic (PV system.

  Although clouds may affect solar panels in a minimal way, solar power is still one of the cleanest, greenest forms of renewable energy.  The cost of solar energy has continued to fall over recent years, as well.  Yet, the reality is that cloud cover can reduce the efficiency of solar panels because their output reacts rapidly to changes in the intensity of sunlight.

  Yet, solar technology continues to advance allowing greater amounts of energy to be collected from solar panels, even when its cloudy.  In fact, solar planners may be able to soon analyze the characteristics of cloud shadows, and reliably model, or predict output from, their individual systems over time.

  For more information on the impact of clouds on solar panels, take a look at NREL’s Measurement and Instrumentation Data Center (MIDC) website.

  What are Solar Panel Kits?

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  

  Solar panel kits

  Looking for easy to install, affordable residential solar panels?  You might want to consider solar panel kits.

  Solar kits include everything you need for a renewable energy installation on your home.  Whether you are looking for a DIY home improvement project, or simply trying to avoid the hassle of contracting with a solar power company to purchase individual components of a system and then have them installed, a solar panel kit could be your answer.

  Solar panel kits allow property owners to go “solar out of the box.”  The solar kits include photovoltaic (PV) solar panels, an inverter, and charge controllers. You will have to assemble the  solar array yourself.

  If you are considering a solar panel kit, you can find a range of options at a variety of price points, wattage, and more.

  More expensive solar kits generally include more 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 costs nearly $9000, before federal and state incentives and rebates.

  Amazon.com sells a less expensive ($479) solar panel kit, which is well-suited for recreational vehicles (RVs), boats or swimming pools.

  In general, residential solar panels are less expensive when you go with a solar panel kit.  This is in large part because you do not have to invest in installation services.  Moreover, with a solar kit, you can purchase one (or more) that more precisely meet your needs.  Many people prefer them to traditional solar panels because they can be modified to meet specific energy needs.

  Solar panel kits are a great DIY home improvement project.  Or purchase a kit for your RV or boat and enjoy free solar power!

  Is a Solar iPhone in the Works?

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  

  Is a solar iPhone in the future?

  Solar cell phones have been gradually hitting the market over the past year.  But the most popular phone, Apple’s iPhone may soon take solar cell phones mainstream.

  Many have been wondering, is a solar iPhone in the works, after discovering that Apple won a patent related to use of solar power in mobile devices.

  Although Apple is not the first company to consider solar powering its devices, its influence in the market will arguably be the most effective in getting consumers to seriously think about portable solar power.  Why?  Because many people consider Apple to be the technological leader in the industry.  Incorporation of solar power could have a broad-based ripple effect across other competitors, as well.

  Apple’s new patent is related to an earlier solar-related patent it won in 2011.  The filing for the new patent explains:

  “The voltage converter is configured to monitor or detect an amount of power drawn by the electronic load at the output of the voltage converter.”  The controller responds and controls the converter, conditioning the power used by the device. “As a result, the output voltage from the solar power source is maintained within a predetermined range.”

  The question is when and if a solar iPhone will be released anytime soon.  Experts are predicting that the iPhone 5 will be launched in October 2011.  But will it include solar panels for recharging ease?  And, if so, will Apple develop its own solar cells for incorporation, or rely on a third-party solar cell company.

  Use of solar power to recharge electronic devices like cell phones is a smart, inexpensive way for people to stay in touch when they are away from electrical outlets and generally on the go (think students, recreational enthusiasts and more).  If a solar iPhone is in the works, Apple may just be timing its solar cell phone so that it will be remembered as the pioneer of this influential technology.

  Solar Powered Restaurants: Fast Food, Green Energy

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  We all know that fast food isn’t good for us.  Yet, as a working mom of 4, I have to admit that about once a week, I let one of these outlets make dinner for us.  Perhaps I can cut down on the guilt by looking at the fact that many of these outlets are converting to become solar powered restaurants.

  Who knew that fast food and green energy would be used in the same sentence?

  

  Solar panels on fast food restaurant rooftops

  I’d heard about McDonalds saving its deep fryer grease to be reused for fuel.  Now, the installation of solar panels on chain restaurants are the latest way that fast food is going green.  There are a number of chains that are increasingly making the shift to solar power, which can help you feel just *that* much better about indulging in a little comfort food.

  1.  Chipotle

  We blogged about solar panels on Chipotle restaurants previously.  The Denver-based fast food restaurant has installed rooftop solar panels on 75 of its restaurants nationwide. Each solar power system will produce about 500 kilowatt hours of electricity, which makes it the largest direct producer of solar energy in the restaurant industry.  With these solar panels, the restaurants can avoid the release of 41 million pounds of CO2 emissions.

  2.  Habana Outpost

  While not known nationwide as a fast food chain, the Habana Outpost opened in Brooklyn in 2005, and became New York’s first solar powered restaurant.  Each year, you can enjoy fare at the site from Earth Day to Halloween. The Habana Outpost’s sustainable solutions include a $40,000 solar installation on its outdoor patio, a bike-powered blender, a rainwater collection system, composting and recycling stations, efficient lighting, compostable plates and silverware, a garden, and wheatboard panels inside the restaurant.

  3.  Burger King

  In Waghäusel, Germany, this solar powered restaurant features solar, wind, lighting, heating and cooling system, all of which will cut whopping amounts of energy and costs at Burger King. The solar and wind systems alone can supply the restaurant with 1/3 of its electrical needs. Overall, the renewable energy systems will reduce energy costs by 45% and reduce CO2 emissions by 120 metric tons each year. More than 720 solar PV modules will generate over 53,500 kWh of electricity per year. The restaurant uses an interior heat-recovery ventilation system to heat and cool the site, waste heat to generate hot water, LED lighting, and a broiler that reduces gas consumption by 52 percent and electrical consumption by 90%. In addition, the restaurant has a solar powered electric vehicle charging station and a rainwater reclamation for landscaping irrigation.

  Wow.  I cannot think of many businesses that are so invested in solar power and reducing environmental impacts!

  4.  Sonic Drive-In

  Right here in my home state, one of my favorite fast food restaurants, Sonic Drive-In, is going solar.  In Wilsonville, Oregon (about 20 minutes south of Portland), a solar panel system has been installed on its rooftop.  The 45-panel system will be able to generate more than 11,380 kilowatt hours (kWh) of electricity per year, which will cut about 8,648 pounds of CO2 emissions per year.

  These fast food outlets are not the only ones going green.  Do you know of a solar powered restaurant in your hometown?  Be sure to share in the comment section below.

  All Electric Ford Focus Will Include Optional Rooftop Solar Power System

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  Last winter, I got the opportunity to attend the North American Auto Show in Detroit, Michigan, as a guest of Ford Motor Company.   Among the numerous fuel efficient vehicles, the showroom included many future electric cars.  Many are merely prototypes, but a few – like the all electric Ford Focus – are actually coming to roadways in the near future.

  The 2012 Ford Focus Electric will be available for purchase or leasing in early 2012.  Ford is teaming up with solar power company SunPower to “take solar mainstream,” according to Tom Werner, SunPower CEO.  And how?

  The all electric Ford Focus will include an option for a 2.5 kilowatt (kW) rooftop solar power system for consumers purchasing the vehicle at a Ford dealership.  The solar power generator can be either bought for $10,000 or leased.  The SunPower generator can charge up the electric Ford Focus, giving the vehicle an additional 1,000 miles per month, and may even have additional energy to power installed appliances.

  If you are in the market for an Electric Ford Focus, you’ll probably want a home-based electric vehicle charging station, as well (240-volts).  Best Buy will be selling these to help you quickly and efficiently charge your EV.  In the meantime, the cost for the all Electric Ford Focus (with or without the optional rooftop solar power system) is not yet set.  Stay tuned and we’ll soon find out the price point for this green vehicle.

  Solar Car Racing

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  

  Solar car racing

  Solar car racing has been increasingly popular since it first hit the scene in 1985.  Way back then, the Tour de Sol started in Switzerland and continued for five days.  The field was small, with only 72 cars at the start line, and a mere 52 that finished the face.  But interest in solar cars has been increasing ever since!

  Today, universities around the world participate in solar car racing.  These events help develop engineering and technological skills.  The American Solar Challenge (originally Sunrayce USA), has been a solar car racing event since 1990.   It was originally sponsored by GM, and since then  – with the exception of two years – has been an annual event, ranging in distance from about 1,000 to 2,400 miles.  The World Solar Challenge is another great solar race!  Each year, participants cover 1,800 miles through the Australian Outback.

  With solar car racing, there are a lot of components that have to be considered in building the vehicle itself.  Among other things, solar panels need to be installed so they sit perpendicular to the sun.  And, each solar car can only have 5 kilowatts (kW) of stored solar energy, which halts racing overnight until the sun comes up again.  Then, the teams and drivers come into play.  No more than 4 people (and no less than 2) may comprise a team.  Drivers cannot be too light, either, to give a team an unfair advantage.  Weigh less than 180 pounds and the car will have to include a ballast to make up the difference.

  Lest you think that solar cars are sluggish and slow, you might be surprised to learn that the 68 mph limit actually handicapped several teams.  In 2009, the winner of the Solar World Challenge averaged 62 miles per hour.

  What do you think of solar car racing? A fad, or the wave of the future?

  Solar powered parking structures

  Over the past few years, we’ve been posting about solar powered parking structures.  These include parking garages or park-and-ride facilities that use solar panels to either power the lighting and other electricity needs and/or re-charge electric vehicles (EVs) that are stationed there.

  With more consumers considering EVs, there is a need for people using parking structures to re-charge batteries quickly and at a low cost.  That’s where solar powered parking structures come into play.  Using solar panels to shade vehicles while generating electricity, drivers can plug in, then go shop, work or commute and return to a fully charged electric vehicle.

  One of the best known options is the Solar Tree, made by Envision, which has experienced sales growth to $2 million in the first half of 2011.  Used in commercial parking lots, each of these “trees” provides shade for 6 parking stalls at the same time it generates 28,000 kilowatt hours (kWh) of solar electricity – enough to charge six electric cars each day.  In addition, the solar power can be used to power lighting for the parking lot or garage.

  Saving municipalities or other property owners money on utilities, while providing necessary infrastructure to help people transition to electric vehicles, solar powered parking structures soon will be found in more and more locations.

  What Effects From Installing Rooftop Solar Panels?

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  

  Do you know the side effects of installing solar panels?

  For residential property owners considering solar power, there are many questions that you’ll want to have answered.  Beyond cost and efficiency, some of the most pressing inquiries have to do with the effects from installing rooftop solar panels.

  In other words, how will things change for you and your property after putting in a solar array?

  1.  Will the property taxes on my home increase after installing a solar power system?

  Fortunately, the answer is No!  Even though homes with solar panels increase in value by $20 per $1 in annual electricity costs saved, laws in the United States prohibit local government from increasing your property taxes as a result.

  2.  What if my Homeowners Association (HOA) prohibits or restricts solar panels on homes?

  In many areas of the country, you will have to be prepared to potentially appeal an adverse decision of your homeowners association regarding solar panels.  A good land use attorney is an ally to have on your side.  For people who live in California, the California Solar Rights Act provides that neither HOAs nor any other organization or governmental entity can keep you from installing a solar power system on your home.  The only powers that can be exercised is to require alteration or location of solar panels to preserve aesthetic appearance, provided they do not increase the price by more than $2000, or decrease efficiency by 10% or more.

  3.  How much rooftop space is required for a home solar power system?

  This is a relatively easy answer.  Most home solar power systems need about 100 square feet of space for every kilowatt produced.  As a result, the average system needs between 300 and 600 square feet for installation of solar panels. If your rooftop space is not adequate in size or solar irradiation, you might consider a ground-mounted system.

  4.  Will a solar power system put too much weight on my roof?

  Generally no.  Less than 4 pounds per square foot in weight may be added with rooftop solar panels.  When you go with professional installation, contractors will ensure that the solar panel system will not damage the roof.

  5.   What type of roof is best for a home solar panel system?

  While solar panels can be installed on just about any kind of rooftop, the best results are from slanted roofs, facing toward the equator, which are unobstructed.  Roofing materials should be of composites, and the roof itself should be able to allow easy access to the solar panels for maintenance or repair.

  Now that you know the effects of installing rooftop solar panels, what is holding you back?

  Building Integrated Photovoltaics: Solar Shingles

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  For people who want to switch to solar power, but are worried about the cost and appearance of solar panels, building integrated photovoltaics (BIPV) may be the answer!  Expense aside, many homeowners do not want to impact the aesthetics of their property and – perhaps even worse – some homeowners associations prohibit solar panels because they are bulky and ugly.

  

  Solar shingles: building integrated photovoltaics

  That’s where BIPV comes into play.  With solar panels that are “built into” a structure, such as solar shingles, you can enjoy a streamlined appearance that are practically invisible.  These rooftop installations lie flat against the top of a home or building and can last as long as ordinary roofing materials, but they do not require roof penetrations to install and also are lightweight.

  Building integrated photovoltaics are favored by many property owners because they are either invisible, or difficult to see from obscure angles, particularly where the south-facing facade of the home is also the front/street side.

  Solar shingles look exactly like ordinary roofing shingles in their shape and size, but they are created with photovoltaic (PV) materials so that they become mini solar panels on your roof.

  Even though solar shingles are wonderful from an appearance standpoint, there are a few downsides: (1) price – they are more expensive than regular solar panels; (2) they are not as efficient than PV panels, which means you need more (adding to the cost for the product itself and installation); and (3) they only come in black – so, if your roof is red tile, brown or any other color, solar shingles will not blend in quite as well as you might hope.

  In summary, before you go with BIPV installations such as solar shingles, do some research and determine the pros and cons from your own personal standpoint.  Hopefully, you can find a way to go solar!

  How Does Heat Affect Solar Panels?

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  

  How does heat affect solar panels?

  Here we are in the “dog days” of summer.  Record temperatures over much of the U.S. might have some people wondering, how does heat affect solar panels?

  The answer can be summarized in a single phrase:  less power.

  As days get hotter – or in regions in which it is often warm – solar panels may experience a decrease in electric output.  In short, solar panel efficiency is negatively affected by heat.

  This may be an ironic outcome, given that abundant sunshine generally means increased solar power generation.  But when comparing equivalent exposure to UV light, solar panels in cooler locations generate more power than their hot weather counterparts.  The difference is often made up by the greater numbers of sunny days in warm locations.  Or, if you live in a sunny, higher elevation climate, your solar panels may perform quite well, comparatively.

  If you are scratching our head, be sure to talk to a solar engineer who can help you determine where to install solar panels, how many to use, and how much the cost will be.

  Solar Panels Cooling Effects

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  We’ve posted a number of times about solar powered air conditioning, also known as solar cooling. It should come as no surprise that solar electricity generated by photovoltaic (PV) panels can be used to operate A/C systems and solar attic fans.  But solar panels cooling effects go beyond just creating solar energy.

  

  Can solar panels cool buildings?

  At UC San Diego this year, professor Jan Kleissl, professor of engineering, and a group of students were preparing  for a upcoming conference at the Powell Structural Systems Laboratory.  The Laboratory rooftop is substantially covered with solar panels, some of which are tilted, and some of which are flush with the roof.

  Using a thermal infrared camera, the students took photographs of the entire roof surface, comparing areas that were covered with solar panels with bare patches.  The reason?  To confirm the hypothesis that the solar panels themselves were cooling the building.

  After initial results, the group launched a scientific study to determine the extent of solar panels cooling effects. The study will be published in an issue of the industry journal Solar Energy.

  The study showed that not only do solar panels generate clean solar energy for homes or workplaces, they can also cool it. The team discovered the Laboratory ceiling under the solar panels was 5° F cooler than it was under the sections of exposed roof. Conversely, at night the panels help to retain heat.

  

  How do solar panels cool buildings?

  The UC San Diego research time discovered that rooftop solar panels act as roof shades. Without solar panels, bare roofs allow radiant heat to be pushed indoors from the roof.  When solar panels cover the roof of a structure, they absorb much of the heat.  Flat panels are effective, but tilted solar panels allow air circulation between the structure and the roof, with additional cooling benefits.  As much as a 38% reduction of heat can be achieved with solar panels on a roof.

  This can translate into energy savings, with less electricity required to keep interiors cool.  The team reported that the amount saved on cooling was equivalent to getting a 5% discount on the price of solar panels!

  Solar Powered Home Electric Vehicle Charging Stations

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  

  Rooftop solar panels power home based electric vehicle charging stations

  Home electric vehicle charging stations are being installed all over the world, as drivers switch out their fuel combustion engines for clean, battery-powered EVs.

  Experts estimate that electric cars charged with solar power can save consumers up to 77% on fuel costs.  Home-based charging stations are convenient and can fully charge an electric vehicle in half the time it would take plugging into an ordinary 120-volt outlet.

  Solar powered home electric vehicle charging stations run on energy from the sun, rather than grid-based power which is often produced by burning coal or natural gas.  Recently, SolarCity and ClipperCreek joined forces to provide solar powered chargers that are compatible with all new EVs on the market.  Lyndon Rive, CEO of SolarCity, commented:

  “SolarCity’s mission has always been to help homeowners and businesses adopt clean power while saving on energy costs.  Electric cars are already among the cleanest-running vehicles on the road—charging them on solar makes them that much better. Tens of thousands of electric cars will be delivered over the next year alone, with hundreds of thousands expected over the next five years. We’re making it easier to power them with carbon-free electricity for zero emissions as well as dramatically reducing the cost of driving.”

  Installation of a ClipperCreek 240-volt Level II EV charger starts around $1,500.  Recharging an electric vehicle with solar power allows consumers to drastically slash transportation costs.  The average San Francisco Bay Area driver spends $230 a month on gas.  Switching to an EV alone would drop that monthly cost to about $107 (using grid-based electricity).  If a rooftop solar system is leased from SolarCity for a solar powered home electric vehicle charging station, that same driver would spend only $54 a month – for the same miles driven!

  Most electric car owners have switched from gas-powered cars to save money and/or to save the environment.  A solar powered home electric vehicle charging station is the cleanest, most convenient and least expensive way to “fuel” up your car and get around town.

  Should You Install Home Solar Panels?

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  

  Residential solar panels

  With rising energy costs and concerns about global climate change, many homeowners are considering renewable energy options. Under the current circumstances, including the economy and technology, you might be asking: should you install home solar panels?

  Residential solar panels are more affordable than ever.  Federal, state and local incentives are still available to help you trim even more off your energy budget and investment.

  Before you consider residential solar panels, you should determine whether solar is right for your home/family.  The following factors come into play:

  • Solar panel cost
  • Solar incentives available
  • Overall energy usage – the less you use, the fewer solar panels you will need
  • Whether your appliances are energy-efficient (requiring less electricity to power)
  • Is your property and your home situated for solar panels?  You will need a south-facing section of your rooftop for maximum solar exposure

  Purchasing home solar panels will still set you back $15-30,000 or more.  If you don’t want to pay upfront, you can still go solar.  Consider a solar panel lease, which will allow you the ability to save on your energy bills and reduce your carbon footprint.

  The answer to the question, should you install home solar panels, is an individual one.  Each family and homeowner has unique circumstances that affect whether solar energy is a good alternative to grid-based electricity.

  Solar Powered EV Charging Station at Mitsubishi Headquarters

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  

  Mitsubishi's Solar Powered EV Charging Station

  Electric cars have been rapidly going mainstream this year with the Chevy Volt and Nissan Leaf now available for consumer purchase.

  Yet, some people question whether electricity is a “greener” fuel than gasoline.  With solar powered EV charging stations, like the one at Mitsubishi Headquarters North America (in Cypress, California), you can drive your car on clean, renewable energy.

  Watch this video showing how solar power can be used to charge the batteries of electric cars:

  Solar charging stations are 100% emissions-free.  UV light is absorbed by solar panels and converted into electricity that can be used to recharge batteries of electric cars.

  At Mitsubishi Headquarters, the new solar powered EV charging station is a symbol of the company’s commitment to these cars of the future, as well as a “kick-off” for the manufacturer’s scheduled launch date in November 2011 of the electric Mitsubishi i in each state.  (you can now place a pre-order for the EV, if you wish)

  Solar battery charging at Mitsubishi Electric is powered by 96 photovoltaic (PV) 175W panels.  The solar electric vehicle charging station can charge up to four vehicles at once and features three types of chargers with different voltages: standard level 1 voltage (110v) will deliver a 100 percent charge in 22 hours on the new Mitsubishi i; level 2 (220v) which can charge the vehicle in six hours; and level 3 CHAdeMO Quick Charger, which can charge to 80 percent battery capacity in 25 minutes.  WOW!

  Katsuya Takamiya, president and chief executive officer of Mitsubishi Electric & Electronics USA, commented:

  “This project will build awareness of solar power’s versatility and efficiency.  As electric vehicles’ popularity grows, we expect to see more charging stations at large employers, automobile dealerships, shopping centers and schools, where cars can charge while people work, shop or study.”

  Mitsubishi Electric has also noted that its solar panels are made with 100 percent lead-free solder, and have one of the higher sunlight-to-energy conversion ratios in the industry.

  Green energy for green driving…. not to mention the “green” you can save by driving an electric car charged with solar power!

  Building Integrated Photovoltaics: Invisible Solar Panels

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  Building integrated photovoltaics (or BIPV) is one of the hottest trends for solar power.  For property owners looking to generate solar energy on site, but not willing to impact the aesthetic appearance of their home or building, solar panes that are incorporated right into the building design are the way to go.

  

  Building Integrated Photovoltaics

  As shown above, building integrated photovoltaics is the practice of “building in,” if you will, solar panels or solar cells to a completed structure.  The solar panels become part of the building design.  Thus, instead of using clunky, thick solar panels on your rooftop, BIPV may include “peel and stick” solar panels, solar windows, solar paint and solar shingles.

  When you go with building integrated photovoltaics, you not only improve the appearance of your building, but you can also save money on both materials and installations.

  There are several primary types of BIVP:

  1.  Solar Roofing

  Solar roofing using BIPV technology consists primarily of solar shingles or solar tiles, but can also incorporate peel and stick solar panels (also known as solar laminate panels). The thin profile is aesthetically pleasing and often virtually invisible, as the roofing material is literally incorporated into the roof itself.

  If you own a metal or flat roof, solar laminate panels may be for you.  They are easy to install and you can have solar power within a hour!

  2.  Solar Paint

  Solar paint has great promise. It incorporates dye-sensitized solar cells under a layer of electrolyte or titanium dioxide and is painted onto sheets of metal.  When sunlight hits the solar cells, it excites molecules that function as light absorbers. Electrons are released into the titanium layer of the paint which acts as a circuit. Electrons move into the dye, generating electricity.

  Compared to regular PV solar cells, solar paint can absorb sunlight across the spectrum, including low radiation frequencies.  And, it is more cost-effective to construct a building with components that incorporate solar paint than later installing solar panels.

  

  Solar windows

  3. Solar Windows

  Miniature PV cell technology can also be used on windows coated with semi-transparent solar cells. Solar windows have a solar film rolled onto a glass pane to reduce UV light and glare, and to provide shading for the interior of a building (consider west-facing windows late in the afternoon). The film has an insulating effect – reducing heat during the hottest part of the day, and preventing its escape when it cools down. In other words, while you are capturing solar energy and converting it to free electricity, you can also be lowering your heating and A/C costs.

  There are a variety of hues of solar film for windows, and the options range from nearly transparent to heavy shade, depending on your desires.  The technology has also been applied to sun roofs in vehicles – the 2010 Toyota Prius is an excellent example.

  Solar Powered Camping

  If you enjoy spending time outdoors, then you know that keeping your electronics fully charged is important.  Not only will you need your cell phone ready to use in case of an emergency, but its also helpful to have a handy GPS, camera, mP3 player and more.  Solar power is the answer to the lack of electrical outlets in the great outdoors.

  Solar powered camping is a great way to enjoy “getting away from it all,” in a safe manner.  As many outdoor enthusiasts know, hiking and recreating in the back country is exhilarating.  But if something goes wrong, not having the ability to connect with family, friends or emergency services can be dangerous.  Being able to cook meals, boil water is also a necessity – and solar panels can generate power for all of these functions.

  With portable solar power charging devices, you can use solar energy to re-charge batteries, make sure that you are not caught without a working flashlight, and even cook your meals without propane.

  There is a wide range of portable solar power options on the market, all of which rely on solar cells to recharge batteries.  One of the first items that campers might want to consider is a solar powered backpack.  You can plug in a number of electronic devices and the solar cells on the outside of the bag absorb sunlight which is used to recharge batteries.  Its easy to convert regular packs into solar backpacks with a solar strap, as well.

  For a broader range of applications and for extra power needs, think about a roll-up solar panel like the one shown below:

  

  Roll up solar panels

  Finally, forget campfires for cooking.  More efficient and safe is a solar oven.  It is easy to build your own solar cooker; then you can prepare dinner and it will cook all day – without the need for fuel – ready when you return to camp.

  Go easy on the environment and consider solar powered camping for your next adventure!  Its convenient and free to tap into solar energy for a comfortable outdoor experience.

  Solar battery charger

  These days, its hard to imagine life without a fully charged and functioning cell phone – which may include a camera, GPS device, mP3 player and portal to the Internet.  With all these operations, its no wonder that smart phones do not stay charged for long.  That’s where solar battery charging comes into play.

  With portable solar power, you can keep any electronic device operational, even if you are away from an electrical outlet.  In fact, any person that spends time outdoors should have one of the solar power chargers on the market!

  Whether you are walking across campus or studying outdoors,  re-charge your phone or computer with a solar backpack or handbag.

  For women, you can select among various solar handbags. They have solar panels incorporated into the fabric and also include USB ports for easy plug-in and charging of a variety of devices.

  If you are someone who loves hiking, camping, hunting or fishing, then consider either the roll-out solar panels, or a solar strap. Thin film solar technology is incorporated to allow for flexible, light and very portable solar power.

  Obviously, convenience is a key consideration when it comes to keeping your batteries charged. When you don’t even notice your power source being toted along with your other gear, that is a huge plus, in my book!

  Solar Pool Heater keeps water warm without electricity

  If you are looking for a way to heat an outdoor, above-ground pool without electricity, then this solar pool heater from Hammacher Schlemmer is for you!  More and more people are looking to solar power for their backyard recreation and enjoyment.  From solar outdoor lights, to solar lawn mowers, you could significantly slash energy bills and carbon emissions with this ample renewable resource.

  This solar pool heater attaches to a regular pump-operated filter system.  Water is pumped through 20 feet of coiled black piping in which the water is heated through exposure to sunlight.  After traveling through the black piping, the warm water is then pumped back into the pool.

  Unlike other solar hot water heaters, the solar pool heater will not warm water to high temperatures.  In fact, it simply helps reduce the chill of water used for above ground pools.  The pool heating system can increase the temperature of a 6,000 gallon pool by 5 degrees F in 10 days.  If you want faster, more dramatic results, up to 4 solar pool heaters can be used at a time to boost water temps by 20 degrees or more.

  This Solar Pool Heater comes with all required hardware and accessories to connect it to an above ground pool and its pump-operated filtering system. It also comes with a protective cover to protect the heater while it is in storage over the cooler months.

  The solar water heater system costs about $199.

  Is Your Solar Contractor Licensed?

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  Looking to install solar panels on your home or business?  Before you line up professional solar installers, you’ll want to check more than just cost and their schedules.  One of the most important questions is to determine whether your solar contractor is licensed.

  

  Is Your Solar Contractor Licensed?

  In many jurisdictions, you can sell solar panels with little governmental oversight.  When it comes to installation, repair or maintenance, you might have to be licensed as a solar dealer.  During this struggling economy, the result has been that ordinary construction workers/home builders with little to do, have tried to get into the solar industry.  Not always with the best outcome!

  Why is it important to determine if your solar contractor is licensed?  There are several reasons.  First, if there is any error in the installation itself, you can look to both the company and their insurance to recoup any damages.   Second, licensed solar contractors can work with you to maximize tax savings and incentives.  Finally, working with a solar contractor that is licensed can give you peace of mind.  If anything goes wrong, you have a stronger case for legal recourse.

  Be sure to carefully review your contract before signing it, and hire an attorney if you have any questions or concerns.

  Powerfilm Inc., a manufacturer of flexible solar film has applied its roll-to-roll proprietary manufacturing technology to produce flexible thin film solar panels.  Shown below, the thin film solar application includes interconnected backplane transistors with built in drivers for the front plane so that individual pixels can be turned on and off.

  

  Powerfilm Thin Film Solar

  Powerfilm manufactures flexible solar film, applied in Building Integrated Photovoltaics (BIPV) to generate solar electricity from the vertical faces of buildings or windows. Flexible solar film is also a great innovation for bus shelters roofs and golf cart canopies.

  Flexible thin film solar rolls, as shown to the left, are less expensive and just as efficient as other PV panels.  Roll-to-roll manufacturing is akin to newspaper printing and can produce long continuous strips.

  PowerFilm will produce 1 meter wide and up to 2400 feet long strips. The interconnection between the transistors is made fully automatic on the machine, eliminating the cost and quality issues with manual interconnection. The substrate is made of polyimide and can be encapsulated in a variety of materials depending on the end application and environmental conditions.

  PowerFilm flexible solar electronic technology includes fabric or fiberglass backing for easy installation of the thin film solar panels.

  Powerfilm licensed technology for self aligning imprint lithography from HP for the development of the backplane, which took  5 years of research and development. Flexible displays are useful for large outdoor advertising displays, e-book readers and other applications, where the lower cost and the self-power feature of this thin film solar application would be helpful.

  Building Integrated Photovoltaics: Solar Panels that Double as Skylights

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  

  Solar panels that double as skylights? Really!

  We love the idea of building integrated photovoltaics (BIPV), yet beyond solar shingles or solar windows, what can you really do to integrate solar electricity generating building materials into your home?

  Consider these solar panels that double as skylights, developed by Architect Gerald Choi.  Personally, Choi needed to update some skylights in his home, but the estimate shocked him at over $50,000.

  Spurred on by necessity, Choi invented combination bi-facial skylight PV system.  These skylights/solar panels allow sunlight/moonlight to flow in, while solar power is generated.  Not only that, but the system is practically hidden from view!

  When working on his revolutionary solar panels/skylights, Choi discovered that he could slash the $26,000 retail cost for the materials to only $13,000 due to solar rebates and government tax credits.  And, since installing the BIPV system, Choi’s utility bills have dropped to $18 a month.  The solar panels that double as skylights produce enough energy that Choi can take advantage of net metering to sell back extra electricity to the local grid.

  Jerrod Schreck, president of Hoku Solar and the man that helped design Choi’s system, comments that we will see more BIPV developments in the near future:

  “I see the time coming when PV systems are architecturally integrated [into the structure]. We’re going to be developing PV systems working with architects. When they start drawing new buildings, they’ll already be talking about the energy load.”

  This is the time at which we are seeing convergence of design with economics.  Sleek, more invisible means of generating clean solar power will become more popular and affordable as we move away from our dirty, fossil fuel habits.

  Disadvantages of Solar Panel Leases

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  

  What are the disadvantages of a solar panel lease?

  We have been pretty excited about the idea of leasing solar panels to avoid the upfront cost of purchasing a solar power system.  For many homeowners, residential solar leasing is the only way they can switch to the renewable energy resource.

  A solar panel lease typically involves a company that owns, installs and maintains the solar panels on your home.  You sign a contract under which you will pay the company a monthly fee that is less than the current cost of your electricity (these are called solar power purchase agreements, or PPAs).  The length of solar leases varies, but are generally 10-20 years.  They may be assignable to a new owner if you sell your home, but be sure to check before entering a solar panel lease.

  While there are some definite advantages to going green and saving the money required to invest in a solar power system, a lease is not 100% perfect.  Consider these disadvantages of solar panel leases:

  First, switching to solar power is usually a means by which you can take charge of your own power.  But with a residential solar lease, you are still dependent on an outside company for your electricity.  In other words, you have switched one utility for another.  Even with significant savings in your power bills, you will not enjoy the freedom of relying on your own generation of electricity.

  Second, you lose the ability to enjoy the benefits of net metering.  This is when you generate more solar electricity than you need and the excess is fed back into the grid.  Then, when you draw on grid-based power, you can use the credit you have earned to off-set any charges.  Some families can even earn a profit under net metering arrangements!

  Third, under solar panel leases, the homeowner does not get the benefit of generous tax incentives that offset the cost of a solar power system.  The solar power company enjoys those incentives and may not pass the savings along to you under the contract.

  Finally, residential solar leases often have a long contract period.  As mentioned above, a solar lease may or may not be assignable to a new owner.  Carefully review termination provisions in the lease to make sure that you will not get hit with a penalty or will be required to “buy out” the lease.

  Solar powered attic fans are easy to install and save you energy and money

  Looking for a way to reduce electricity costs in keeping your home cool, as well as cutting down condensation and moisture in the attic?  Solar attic fans (also known as solar powered attic fans) are convenient and cost-effective.

  If you want to keep your attic cool and dry, solar powered attic fans are one of the most inexpensive, functional solar gadgets to hit the market.  Powered 100% without any grid-based electricity, solar fans can be  installed in a matter of hours to immediately save you 30% or more in cooling costs.

  

  Solar powered fans

  Because heat rises, you need to work to keep temperatures down at home starting from the attic.  Trapped heat can make your air conditioning work even harder during summer months.  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.

  If you are considering installing a solar attic fan, many manufacturers and retailers sell models from which you can choose.  Before installing the device,  choose an area of your home that gets regular sunlight exposure.  With these electrical items, a solar panel absorbs UV light, which is converted into power to operate the solar attic fan.

  Solar powered attic fans are sold at many hardware and home improvement stores, including Amazon.com.

  In general, prices range between $250-500.  Solar attic fans are also eligible for energy efficiency tax incentives and tax credits.

  Why not install a solar powered attic fan as a home improvement project this year?

  Passive solar cooling to minimize energy use and expense

  Worried about your power bill as you try to keep temperatures down this season?  Why not use passive solar to cool down this summer?

  Instead of cranking the air conditioning, you can employ a few simple measures to minimize the heat inside.  Passive cooling requires little more than planning ahead and maybe some minor landscaping adjustments.

  You can have a solar home with these easy tips:

  • Plant trees and shrubs on the west sides of your home to act as a buffer from late afternoon sun over the summer and chilly winds in the winter
  • Be generous in landscaping with trees and shrubs – in particular, deciduous versions provide shade and cooling during summer months, but allow light in during the winter
  • Make sure that rooms that generate heat, like the kitchen and laundry room are located on the north side of your home to provide heat where its needed most
  • Install drapes or blinds on windows to block the sun through the summer, and trap heat inside during winter
  • Open windows during summer nights and in cool mornings to help circulate cooler air throughout your home

  Its quite easy to use passive solar to cool down this summer!

  Solar roofing tiles for aesthetically pleasing green electricity

  Let’s face it.  You can usually spot the home with solar panels, right?

  Residential solar power is convenient and efficient, but there are definitely a few strikes against it.  Among them include the cost and aesthetic impact.

  With solar roofing tiles, you can go solar right away without compromising the appearance of of your home.  Solar shingles look just like regular asphalt tiles or ceramic roofing tiles, but they are covered with solar cells to generate clean, cheap solar electricity.

  Home solar power usually requires bulky PV solar panels on the roof.  Not only do they disrupt the roof line, but their blue color is not always appreciated by homeowners or their neighbors.  No wonder so many homeowner associations (HOAs) prohibit solar panels, or require lengthy approval processes for them.

  But now solar roofing tiles are integrated right into the roof line.  That’s why they are the perfect example of building integrated photovoltaics (BIPV).  In addition to their sleek appearance, solar shingles do not require roof penetrations like ordinary solar panels.

  You may be wondering whether solar roofing tiles are more expensive than “regular” solar panels.  When all is considered, the answer is no.  Keep in mind the following: (1) property value is conserved with minimal visual impact, as well as helping homes sell faster; (2) solar power improves home value; (3) solar shingles last as long, or longer, than regular roof tiles; and (4) solar power is reliable and safe, particularly in the case of an emergency.

  Looking for solar lighting options for your yard, driveway, patio or deck?  Solar outdoor lights are better than ever!

  

  Fancy solar outdoor lighting embedded in steps

  Years ago, solar lights were not very bright and didn’t last very long.  But today’s solar garden lights glow nearly as brightly as electric versions and do not require any utility power to operate.  Even more impressive is the fact that you don’t have to bring out an electrician to install your outdoor lights.  Simply position your solar lights were you want and firmly push them into the ground.  Even for more upscale installations as shown above, you still won’t need a professional to help you with wiring!

  

  Beautiful solar outdoor lights

  The advantages of using solar lighting include: (1) reliable illumination – even if the sun is not out, the absorption of UV light will provide power; (2) enjoyment of lighting each day without a concern for electricity bills; (3) soft, pleasing ambiance that doesn’t even require flipping a switch; and (4) ease of installation, replacement and positioning of solar outdoor lights.

  Solar outdoor lights are also inexpensive!  Many home improvement retailers carry DIY kits that allow you to have your outdoor lighting project complete within hours – not days.  For as low as $5 per solar light, or $25 for a kit, you can bring clean, bright solar powered lighting into your backyard today.

  And don’t forget the holidays!  LED holiday lights are brighter and more energy-efficient than their traditional counterparts.

  Next time you are undertaking a home improvement project, why not consider solar outdoor lights?  They are versatile, inexpensive and one of the greenest way to bring ambiance into your outdoor spaces.

  Solar Panels on State Prisons in Colorado

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  

  Solar panels at the Ironwood Facility as part of the Colorado state prison system

  Solar panels on state prisons in Colorado are saving taxpayers money.  As of the date of this publication, nine state prisons have installed solar panel arrays to generate solar electricity and cut operational costs.

  By relying on solar power, the Colorado prison system is expected to save about $475,000 in utility bills over the next 20 years.  It is expensive to run operations at the institutions, but photovoltaic solar panel arrays are helping reduce power bills.

  To date, nine state prisons in Colorado have installed photovoltaic (PV) solar panel arrays to generate solar electricity.  Reducing reliance on grid-based power is both environmentally sound, and a sound investment.  Experts predict that the state prison solar arrays will save Colorado taxpayers about $475,000 in utility bills over the 20-year life of the solar panels.

  In addition to helping defray costs with solar panels on the state prisons, the installations will help inmates learn important job skills that may lead to securing a green job upon release, reducing the risk of recidivism.  Inmates can help with the installation of the solar panels on the prisons.

  Considering the vast stretches of land that surround correctional institutions, why not put some of that property to use with solar power arrays?  State prison systems can save green, while they go green.  Inmates and visitors can learn about the renewable resource, which may translate into a brighter future for all!

  New Solar Cell Technology Gets Boost from Federal Funds

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  

  New solar cell technology allows silicon wafers to be cast without losing material to dust

  The United States Department of Energy is expected to provide a $150 million loan guarantee for a company developing new solar cell technology.  The company, 1366 Technologies, is positioned to revolutionize the manufacturing process of silicon cells, which will make it possible to create cheaper solar panels.

  In fact, estimates are that the cost of manufacturing a solar cell could be cut by 40%.

  The solar technology is used to directly cast silicon wafers (only 200 microns thick, or 8/1000th of an inch) instead of slicing them from a block, which results in about half the material being lost as dust.

  The U.S. Secretary of Energy, Steven Chu, commented:

  “This project is a game-changer that could dramatically lower the cost of photovoltaic solar cells.”

  Federal funding for the new solar cell technology, through the loan guarantee program is consistent with the DOE’s goal of developing a cradle-to-market innovation strategy.

  Identifying promising solar technologies like this one of 1366 Technologies, and then providing support early in the process to help them mature, will eventually benefit everyone.  By streamlining and reducing solar panel production costs, this renewable energy resource becomes more affordable and available to everyone.

  Solar-Powered Hotels for Summer Vacation

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  

  Solar panels on a hotel rooftop

  We loved this post on Peachy Green about solar-powered hotels.  With summer here and people considering vacation, its the perfect time to write about these eco-friendly hotels and resorts.

  Green travel is one of the hottest trends these days.  Today’s travelers look for eco-friendly properties for both business and leisure travel. While there are companies that engage in “green washing,” or overstating some of the environmental benefits of their practices, you cannot fake this energy-efficient installation:  solar panels.

  If you want to stay at a solar powered hotel, consider these options.

  1. Matava Fiji’s Premier Eco Resort on Kadavu Island in Fiji.  The minimal electricity needs at the resort are 100% solar powered, but there is a back-up generator to continue to provide power in case of storms or low sunlight days.

  2. Hyatt Regency New Brunswick in New Jersey.  This green hotel installed a 32,000 square foot, 421 kilowatt SunPower system on the top of the hotel’s garage.  The rooftop solar panels will reduce CO2 emissions by 10,000 tons over 30 years, which will  cut equivalent oil demand by at least 749 barrels each year, per conversion formulas of the U.S. Environmental Protection Agency.

  You can now find solar powered hotels on every continent, except Antarctica!

  3.  Hidden Valley Cabins resort in Australia offers Solar Eco Cabins and an Interpretive Centre.  The property is the country’s first fully carbon neutral resort and tour business and is 100% powered by solar energy.  Hidden Valley has achieved the Ecotourism Australia’s Advanced Ecotourism Certification, as reported by Green Lodging News.

  Instead of staying in large hotels (even with solar panels), green travelers may prefer modest accommodations that are green in every sense of the word.  Norwegian distributor Power Controls AS creates and sells “Smart Energy Station” turnkey vacation cabins with ICP Solar Technologies’ GreenMeter for remote applications.  Wooden log houses, about 6 square meters and sold as outdoor cabins, are currently available in Europe, Canada and Russia.   Solar panels generate electricity for lighting these eco-friendly accommodations.

  Overall, hotels are realizing that they need to offer eco-friendly options for travelers that have an eye on their carbon footprint.  With solar panels on their rooftops, travel properties not only cater to that niche, but also end up saving significant money on their own utility bills.

  Solar Panel Pyramids: Lunar Cubit Acts as Solar Power Plant

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  Solar power art, like these solar panel pyramids forming the “Lunar Cubit” in Abu Dhabi, is a popular way to combine urban art with renewable energy.  Some commentators even believe that these displays can raise awareness of and encourage deployment of other solar power projects.

  

  Lunar Cubit generates clean solar electricity through beautiful urban art

  As part of the project, “Renewable Energy Can be Beautiful,” the Lunar Cubit was developed as a pyramid shaped solar complex with the ability to generate enough solar electricity to power thousands of residences.  Designers entering the Land Art Generator Initiative contest must submit concepts that combine art and renewable energy.  According to the website:

  The main goal of the Land Art Generator Initiative (LAGI) is to design and construct public art installations that have the added benefit of large scale clean energy generation. Each sculpture will continuously distribute clean energy into the electrical grid, with each having the potential to provide power to thousands of homes.

  Perhaps not surprisingly, Lunar Cubit was the winner of the Land Art Generator Initiative in 2011.

  Eight solar panel pyramids enclose a central  pyramid in a semi circle. Solar power generated by the Lunar Cubit can produce enough energy for 250 homes.  Estimates are that the Lunar Cubit could recoup the cost of its construction within 5 years.

  So why is it called the Lunar Cubit?  Because the solar panel pyramids act as a lunar calendar.  The central pyramid lights up in increments, based on the current phase of the moon.  This artistic element of the solar power plant illustrates moon phases, while the smaller pyramids representing the hands of a clock for the eight phases of the lunar calendar.

  Perhaps even more fascinating is the fact that the solar power pyramids were carefully designed to follow ancient moon phase measurements, and is proportionate with the Great Pyramid of Cheops in Giza.

  Portable solar power for your next camping outing

  Are you going camping this summer?  Maybe fishing, hiking or boating?

  Its time to consider a solar power gadget to keep your electronics fully charged so you can stay connected.

  These days, its hard to travel anywhere without a cell phone, mP3 player, computer, GPS device, or even a camera.  Heck, you probably even want some convenient coffee, while you are at it!  Yet all of these devices require a lot of battery power to keep running.

  When you’re in the great outdoors, there is nowhere to plug in for a quick recharge when the power level is running low.  That’s where portable solar power gadgets come into play!

  There are many ways to use sunlight to generate solar power to keep your electronics’ batteries fully charged.  When you’re away from the power grid, you still need to be connected to the rest of the world for health and safety reasons.  Campers and other outdoor recreational enthusiasts may also want to charge up cameras and music players for entertainment.

  We have reviewed solar backpacks, solar lanterns, foldable solar panels, and even solar powered cell phones here.  Before long, there will probably even be solar powered sleeping bags!

  Basically, all you need is some UV exposure and a device with solar panels.  And many solar power gadgets are not even very expensive!  For about $200 or less, you can enjoy outdoor recreation for as long as you like, without worrying about battery life of your electronics.

  So get out and enjoy the sun!  And while you are at it, make it work for you.

  Solar Power Meets Urban Design: Soft Rockers at MIT

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  Ever wonder what it would be like to lounge on your patio or deck and listen to music or work on your laptop, entirely on solar power?  These “Soft Rockers” introduced at MIT’s Festival of Art, Science and Technology this year, combine urban design with solar technology.

  

  Soft Rocker Combines Solar Power with Urban Design

  Cool, sleek lines are obvious in these photos of the solar rocker.  Designed to resemble a leaf, the rocker includes solar panels on its top which generate renewable, portable solar electricity.  The structure uses softwood panels that are “mass-customized” to adapt to the angle of the sun at any site, with parametric design software.

  The Soft Rockers at MIT are truly an ingenious design.  The chair literally self-adjusts based on the weight and position of the person inside so as to maximize solar exposure.  Using the human power of balance, a soft rocker detects body weight and automatically positions its tilt towards the sun to absorb the maximum amount of solar energy.  Each Soft Rocker can create an interactive 1.5 axis 35 watt solar tracking system using this technology.  Then, the solar energy generated can be stored by soft power electronics that charge the rocker’s battery.

  

  Hang out in a solar powered soft rocker at MIT

  If the ingenious design and concept isn’t impressive enough, consider that the Soft Rockers include a USB port that allows users to plug in portable electronics for a cool, lazy afternoon of music, or perhaps more realistically a boost for computers or cell phones so that these smart students can continue to “generate” high grades!

  Solar Panels on Toyota Motor Manufacturing Plant in the UK

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  

  Toyta is going solar in the UK

  Auto manufacturers are increasingly turning to renewable energy to cut costs and save energy.  This week, we heard that solar panels on the Toyota manufacturing plant in the UK are planned to be installed, allowing Toyota to use solar energy to build cars.

  Partnering with British Gas, Toyota Motor Manufacturing UK submitted a land use application seeking approval of a ground-mounted solar array that will include 17,000 solar panels.  It will be sited on industrial land within the Toyota plant’s perimeter fence.

  The solar installation will offset about 5% of the electricity demand of its plant in Burnaston.  Perhaps more impressively, Toyota’s solar panels will prevent 45,000 tons of CO2 from going into the atmosphere over the life of the project.

  Toyota Deputy Managing Director, Tony Walker, commented:

  “Using solar power to supply electricity to the plant underlines our commitment to the UK’s low-carbon economy and our own ambitions to further reduce our carbon footprint.”

  Toyota and British Gas will enter a solar power purchase agreement, whereby British Gas will install and own the solar panels, and will claim the feed-in tariff, and the clean solar electricity generated by the solar array will be purchased by Toyota at a rate lower than grid-based power.

  A new solar railway tunnel in Europe will be sited in the City of Antwerp on the link between Paris and Amsterdam.  Using solar panels to generate electricity, the tunnel is expected to save millions and millions of tons of CO2 emissions.

  The solar railway tunnel will be powered by 50,000 solar panels, over a space the size of approximately 8 football fields.  The solar electricity generated by the panels will help power trains passing through at speeds up to 186 miles per hour.  Excess electricity from the solar tunnel will be fed into the grid to offset energy requirements of the city of Antwerp.

  The new solar transportation project is the first of its kind, but others may follow if this one is successful.  It is projected to generate about 3300 megawatt hours (MWh) of electricity each year, which is enough to power 950 homes.  The solar panels will be built by Belgium-based Efinity.

  Electric cars are the wave of the automotive future, and Hertz Car Rental Company is not about to get left behind!

  

  Hertz Car Rental Company installs solar panels on U.S. facilities

  The company recently announced that it will install 2.3 megawatts of photovoltaic (PV) solar panels at 16 of its car rental facilities in the United States in Arizona, California, Colorado, Georgia, Maryland, Massachusetts, New Jersey, New York, and Pennsylvania this year.  Not only will the solar panels generate clean electricity for the facilities themselves, but also for electric cars that will be offered for consumers.  In other words, you’ll be able to rent a solar powered electric car from Hertz soon!

  Instead of gasoline, solar energy can power rental vehicles.  According to Paula Rivera, manager of Public Affairs at Hertz:

  “Hertz is…committed to sustainable business practices. Investing in solar energy for Hertz facilities makes good business sense.”

  The solar panels Hertz is installing are manufactured by a China-based company, SolarFun.  MartiferSolar, a Portugal-based company, will complete the design of the solar arrays and do the installations.  Hertz expects to receive its full return on investment within 5 years.

  When it comes to electric cars, you can currently rent a Nissan LEAF or Chevy Volt in New York City.  In the near future, more EVs will be available for rental in areas including London, Washington D.C., and San Francisco.

  Solar Technology Improves Solar Cell Efficiency

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  One of the biggest hurdles to widespread adoption of solar power as an energy resource is solar cell efficiency.  That, plus the relatively high cost of solar, means that we currently generate less than 1% of all electricity from solar power.

  

  HyperSolar's solar concentrator improves solar cell efficiency

  HyperSolar, based in Santa Barbara, California has developed a patent-pending solar technology to effectively improve solar cell efficiency.  Ordinarily, efficient solar cells convert only 15% of the energy from sunlight into electricity.  With HyperSolar’s technology, photonics (guiding light) acts like a magnifying glass, concentrating sunlight onto solar cells.

  The company is developing a thin, flat solar concentrator that would be placed on top of existing solar cells.  Not only will the solar concentrator enable solar panels to generate significantly more energy, but its inexpensive to create and install.  The solar technology allows fewer solar cells within a single solar panel, which means less silicon is required, further dropping the cost of solar electricity.

  

  Breakthrough solar technology from HyperSolar

  HyperSolar’s solar concentrator uses four innovations:

  • Micro-concentrators — A matrix of small, highly efficient solar concentrators  collect sunlight from a wide range of angles, eliminating the need for tracking mechanisms
  • Photonics light routing — A solid-state photonics network underneath the micro-concentrators transports light from collection points at the top to the concentrated output points at the bottom
  • Photonics light separation — The photonics network separates collected sunlight into different spectrum ranges, which can be routed to different types of solar cells
  • Photonics thermal management — The heat from unused portions of the solar spectrum is filtered out, thus avoiding overheating, which can degrade solar cell  performance

  HyperSolar plans on entering into a partnership with a PV solar panel manufacturer that will use the solar concentrator to improve solar cell efficiency and reduce costs of solar power.  The potential for this product is huge.  With solar power demand on the rise, consumers are continuing to look for cleaner, cheaper, reliable means of generating electricity.

  Solar Power 24 Hours a Day?

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  Can you imagine solar power 24 hours a day?

  Sounds far-fetched, but it will soon be a reality near Las Vegas.  A new solar power plant being planned in Tonopah, Nevada will use heliostat mirrors to focus sunlight on a water tower, superheating water and creating steam that turns a turbine, generating electricity.  The solar thermal power plant will not require photovoltaic (PV) solar panels to generate solar power.  So-called Concentrated Solar Power (CSP) plants like this one hold great promise for the future of renewable energy.

  

  Concentrated solar power using molten salt can extend solar electricity generation overnight

  The Crescent Dunes Solar Energy Project will also use the focused sunlight to heat millions of gallons of molten salt to temperatures as high as 1,050 degrees Fahrenheit.  While the salt heats the water to produce steam (which turns the turbines to generate power), it also retains heat overnight.  This allows the plant to continue generating solar power throughout the night.

  Using solar thermal technology with inexpensive molten salt will allow SolarReserve to provide power at a cost lower than traditional coal or natural gas.  With the ability to generate solar power 24 hours a day, the power plant will be able to continually feed clean  electricity into the grid at any time, unlike other solar power plants.

  SolarReserve estimates the solar power plant design could extend electricity generation operations by as much as 12 hours.  The Department of Energy recently announced it would guarantee $737 million in loans for the plant. The Crescent Dunes Solar Energy Project is planned to begin operations in 2013.

  Golfing is a (usually) relaxing recreational pursuit, most often enjoyed on sunny days.  So why not draw on solar power for golf carts?  Solar Carts, LLC will start offering its Sun Eagle solar powered golf cart on June 1, 2011.  Actually, the product is a photovoltaic (PV) solar panel retrofit for existing golf carts – that makes it even easier to implement!

  For just $999.99, a 210-watt PV solar panel can be installed on a golf cart.  Solar power will recharge the vehicles batteries instead of conventional charging.  The driving range is usually extended, and electricity costs can be reduced.

  From June 1- July 15, SolarCart is offering the deal to only its first 100 customers in Florida.  After that date, the company will decide whether to extend its offer to additional customers and/or outside of Florida.  Compared to other solar golf carts or retrofits, which range in price from $2,500-$9,000, SolarCart’s deal is much more affordable.  Owners of a Sun Eagle system may also qualify for the 30% solar tax credit.

  Solar Carts is now taking orders and deposits from customers.  The final retail price for a Sun Eagle solar powered golf cart after the promotion ends on July 15 will be determined at a later date.

  Solar Jobs: 2011 Status

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  With solar power leading industry growth in the United States, is it any wonder that solar jobs are also increasing?

  

  It is getting easier to find a solar job

  The solar job market is much different than it was even a few years ago.  And it continues to look promising.  The cost of fuel and electricity is squeezing families that are trying to recover from the recession.  Global climate change threatens crops, shorelines and more.  Solar power appears to be one of the most promising renewable energy resources.

  So, not surprisingly, there are more solar jobs today than there have ever been.  Wondering what type of positions are available?

  • Solar water or pool heating installers or technicians
  • HVAC technicians with skills in solar installations
  • Plumbers with skills in solar installations
  • Production workers
  • Marketing staff
  • In-house legal staff
  • Accountants and accounting clerks or finance staff
  • First-line supervisors or managers of production and operating workers

  Consider these statistics about the solar job market from the National Solar Job Census:

  • There are 93,502 solar workers in the U.S. (double the number in 2009)
  • Solar job growth over the next 12 months is anticipated to be 26%, representing 24,000 net new jobs (significantly higher than the U.S. economy-wide expectation of 2% growth over the same period)
  • Nearly half of all firms expect solar revenue to increase over the next year
  • Over half of all solar employers expect to increase their number of solar jobs in the next 12 months
  • Solar jobs exist in all 50 states

  The following solar jobs are expected to experience the greatest growth:

  1. Photovoltaic installers (51-66% growth)
  2. Electricians with specific experience in solar installations (42-55% growth)
  3. Sales occupations at wholesale trade firms (40-49% growth)
  4. Sales representatives or estimators at installation firms (39-47% growth)
  5. Roofers with specific experience in solar installations (36-49% growth)

  The 2011 status of solar jobs indicates that people looking for jobs should consider the industry.  Employers are having difficulty hiring qualified workers.

  Solmentum sells solar electricity to customers in California

  In the 2 years since it started business in California, Solmentum has completed its 1000 residential solar power project.  With this track record, it is in the top 5 largest residential solar companies in the state.  Its solar power installations benefit 1000 customers and have a combined capacity of 5 megawatts (MW).

  So what is the secret of Solmentum’s success?  According to its CEO, Jason Brown, the company’s strategy is to identify homeowners who can benefit financially from solar power, but may not know their home qualifies for Solmentum projects.

  “Solar only makes financial sense for some people, so we have developed strategies to hyper-target our marketing efforts.”

  Unlike other solar companies that sell solar panels to residential consumers, Solmentum sells metered electricity, like a utility.  In other words, it generates the solar electricity and homeowners can then get the benefits of solar without the upfront cost.  Not only does Solmentum save homeowners money on their utility bills, but its sales strategy is one of the best.  With top notch marketing materials, information and staff, it continues to draw new customers, helping them make the switch to solar electricity.

  More and more businesses are seeing the light, so to speak, when it comes to solar power.  Instead of relying on grid-based electricity which is usually from coal or gas, Southwest Baking, a supplier of dough to Subway stores in Arizona, Nevada, Hawaii, and Southern California announced plans to add a 300 kilowatt (kw) solar energy system at its facility in Tolleson, Arizona.

  The solar array will be ground mounted and is estimated to produce about 480,000 kilowatt hours (kWh) of clean solar electricity each year.  Subway continues to make efforts to reduce its carbon emissions with this latest announcement.  In addition to solar power, the company uses 100% recycled napkins, towel, and tissue products.

  Elizabeth Stewart, Subway’s director of corporate social responsibility, commented:

  “Being a healthy company is about more than just food; it’s about operating in an environmentally responsible manner.”

  Solar Rebate Programs Generous in Southern California

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  Consumers have been tapping into solar rebate programs so that they can maximize the amount of money back for going solar.

  

  Maximize solar savings with rebate programs

  These programs have been especially generous in Southern California.   For customers of Southern California Edison (SCE) solar rebates remain high, at about $1.10 per watt of solar energy systems installed.  To put this amount into perspective, solar power costs homeowners an average of $6 per watt.  So, you can save about 18% with this solar rebate program.  Other solar incentives like the 30% available through the Residential Renewable Energy Tax Credit.  Adding these together, you have practically slashed solar costs by 1/2.  In other words, a solar panel system that costs $25,000 retail is only $12,500 after these generous rebate programs and rebates.

  But you can’t continue to wait.  The Solar rebate programs have a capacity limit, and then incentive levels drop in 1/2.

  If you live in California, check the Statewide Trigger Tracker for updates.  And, if you are not certain whether your home is within the SCE territory and qualifies for its rebates, if you live in the following counties: Los Angeles, Orange County, Santa Barbara, San Bernardino, Riverside, Ventura, Kern, Tulare and Inyo, you may be in luck.

  Tap into these generous solar rebate programs in Southern California before they are reduced or gone!

  Chevy Volt Electric Cars to be Built with Solar Energy

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  

  Solar Panels at a Southeastern GM plant

  When you are building one of the greenest cars on the road, doesn’t it make sense to use green energy?

  At the GM Detroit-Hamtramck assembly plant, one of the largest photovoltaic solar panel arrays in the state of Michigan will allow Chevy Volt electric cars to be built with solar energy.

  The 516-kilowatt new solar project was announced this week by GM and DTE Energy.  The solar electricity generated by the PV solar panel array will be enough to fully charge 150 Chevy Volt electric cars each and every day of the year.

  The energy savings estimated as a result of the solar panel installation at GM’s Detroit-Hamtramck facility will save about $15,000 per year, over 20 years.

  Bob Ferguson, VP of GM Public Policy, stated:

  “This array will significantly decrease energy consumption by combining solar power with ongoing efficiency tactics such as lighting and equipment upgrades and automating equipment shut-down. Making sustainable choices is good for both the environment and our bottom line. Obviously cost savings is critical for GM, and the ability to save $15,000 per year while being environmental serves us well.”

  DTE is investing $3 million in the solar panel array at Detroit-Hamtramck.  The project will be built pursuant to its SolarCurrents program that aims to increase demand for renewable technologies in Michigan.  At the Chevy Volt GM plant, the solar panel array will be constructed on an adjacent tract of land to maximize solar efficiency.  Overall, the project fits nicely into the leading use of renewable energy by GM, compared to others in the auto manufacturing sector.

  Tags:    [edit]

  Any modern day convenience can be run on solar power!  From portable solar power recharging devices to solar water purifiers, there is no end to the uses we can create with solar energy.

  

  Solar coffee machine on display

  A solar coffee machine, as part of a renewable energy project in Abu Dhabi, can create espresso with concentrating solar power (CSP), according to Masdar Power, a unit of the Abu Dhabi Future Energy Company (Masdar).  Recently, the solar coffee machine was unveiled at the Organic Market, at the Masdar Institute of Science and Technology.

  Not only is this use of solar energy practical, but the solar coffee machine helps to demonstrate how solar power will be produced at Shams 1 – a 100 megawatt (MW) project which will generate enough solar energy for 100,000 people by July 2012.

  If you are not familiar with concentrating solar power, as opposed to photovoltaic solar power, CSP uses mirrors to concentrate sunlight and superheat water to create steam, which turns a turbine to generate electricity.

  The solar coffee machine uses about 1/2 liter of water, which is fitted at the center of a solar panel (with coffee grounds at the tip). When sunlight hits the mirrors and is directed to a tube, the water within it is heated quickly, which creates coffee as it is mixed with the grounds.

  The demonstration is not so much to showcase a new way to brew coffee, but to demonstrate the potential of using solar power for a number of everyday uses.

  Tags:    [edit]

  

  Floating solar panels

  Since 2007, SPG Solar has been promoting its floating solar panels to government officials and commercial enterprises, such as wineries and industrial mine owners.  Floating solar panels, or “floatovoltaics” as they are cleverly called, can help increase the use of solar power where it might not otherwise be practical or possible.

  So what does this entail?

  Instead of installing solar panels on rooftops, or even ground-mounted, floating solar panels rest on pontoons on a body of water.  For example, at Far Niente Winery, one of its irrigation pond holds 994 solar panels to help generate clean, green, free solar electricity.

  And, Why is this helpful to the company?  According to Larry Maguire, Far Niente’s CEO:

  “Vineyard land in this part of the Napa Valley runs somewhere between $200,000 and $300,000 an acre.  We wanted to go solar but we didn’t want to pull out vines.”

  Beyond vineyards, other commercial uses could benefit from floating solar panels.  For example, an owner of an industrial gravel mine is considering Floatovoltaics for a settling pond where traditional solar panels may not work otherwise.  Golf courses, amusement parks and other similar uses are also prime candidates for this solar technology.

  Would floating solar panels work for your business?  Using prime “real estate” like ponds with ample sunlight exposure may be just the answer to reducing energy costs and carbon footprints.

  The Impact of Solar Power on National Security

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  Are gas prices giving you heartburn these days?  Well, you can thank recent upheaval in the Middle East, among other things, for the suddenly increased fuel costs.

  

  Solar Energy is Our Answer to Rising Gas Prices

  This turn of events has me reconsidering my father’s advice at least five years ago: reduce your reliance on foreign oil and you increase national security.  Instead of fighting wars in the Middle East to protect oil supplies, why not increase our use of solar power instead?

  Gasoline prices in the U.S. are at $4 per gallon (as of this posting) and could rise as much as an additional $1 per gallon this year.  However, if we switched to electric cars that can be recharged with solar power instead of grid-based electricity, saving money and the environment would be much easier.

  Among other things, government needs to make a shift away from subsidizing big oil and instead invest the money in solar technology.  When it comes to the impact of solar power on National security, the best thing we can do is to rely on our own, home-grown power.

  Peak Oil?  Do we really have to worry about that?

  The Capteur Soleil is a solar energy device that effectively sterilizes medical tools (image credit Jeff Fitlow)

  Improving health conditions in Third World countries can be a challenge, particularly when many regions are remote and/or off-grid.  The lack of electricity makes it difficult to refrigerate medicines and sterilize medical instruments required for surgery.

  Solar power is the answer!  Rice University students have been working on a device originally created by French inventor, Jean Boubour, called Capteur Soleil.  Originally, the invention helped generate electricity from the sun under less than ideal conditions.  The students are modifying Capteur Soleil to use solar energy to superheat water in an autoclave to produce steam to sterilize medical instruments used in Third World countries.

  As shown in the photo above, the modified Capteur Soleil is created with curved mirrors and an insulated box which serves as the autoclave.  Temperatures within the autoclave can quickly reach 121 degrees Celsius, which meets sterilization standards established by the Center for Disease Control.

  In about an hour during mid-day, the Capteur Soleil can superheat water, create steam and sterilize tools and syringes.  Use of the device is easy and can significantly cut down on infections and disease resulting from the use of dirty medical tools, improving the lives of thousands of people who live in remote areas of the world.

  Solar panels on landfills (image from NYDailynews)

  We have recently blogged about the potential of using so-called brownfields for renewable energy development.  In Manhattan, solar panels have been installed on New York City landfills to utilize open space and generate clean electricity.  In fact, developers are vying for a chance to install solar panels on landfills pursuant to the PlaNYC environmental initiative.

  Mayor Michael Bloomberg set forth the first 4-year update to PlaNYC this week, in which he discussed continued efforts to switch from fossil fuels to solar energy.  With solar panels installed on landfills, significant amounts of power can be generated from otherwise fallow sites.

  According to Reuters:

  “Installing solar power at these sites could significantly improve local air quality by reducing generation at the city’s dirtiest plants during periods of peak summer demand.”

  Over time, the plan is to install solar panels over more than 3,000 acres of landfill property.  This would generate the power required for more than 50,000 homes.

  

  Solar Panels on Landfills

  Why use landfills for the property on which to install solar panels?  The biggest reason is probably because the real estate is cheap and is not worth much otherwise.

  NYC is just one of many municipalities that have – or are considering – solar panels installed on its landfills.

  Tags:    [edit]

  A recent story in the New York Times sets forth the top 10 solar power states in the U.S., which might surprise you.

  

  Solar panels on a school in New Jersey

  Actually, the top spot in the list is fairly predictable – its California.  Not only does the state enjoy ample sunshine, but its Million Solar Roofs Initiative has helped to propel large numbers of solar panel rooftop installations.

  In second place after California is New Jersey.  So, how does this Northeastern State rank ahead of sunnier locales like Arizona and Florida?  The state has committed to increase reliance on renewable energy resources like solar power over the next 10 years, which – not surprisingly – means more solar panels installed.  New Jersey has also required all future schools that are constructed to include solar panels on the rooftops.

  The Solar Energy Industries Association reports these top 10 states in order based on installed solar capacity:

  1. California: 47% with 971 megawatts

  2. New Jersey: 14% with 293 MW

  3. Colorado: 5% with 108 MW

  4. Arizona: 5% with 101 MW

  5. Nevada: 5% with 97 MW

  6. Florida: 4% with 73 MW

  7. New York: 3% with 54 MW

  8. Pennsylvania: 3% with 54 MW

  9. New Mexico: 2% with 45 MW

  10. North Carolina: 2% with 42 MW

  Percentages are broken down from a sum of all installed solar capacity across the United States.

  Does your state rank in the top 10 solar power states in the U.S.?  If not, what might be done to increase reliance on renewable energy where you live?

  Uses of Solar Power

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  

  We should rely more on solar power

  The energy from the sun is so powerful, only a fraction of what hits the Earth on a single day could power all of humanity.

  Solar technology is discovering more ways to efficiently and inexpensively tap into solar energy.  Along the way, many uses of solar power have been discovered.

  For thousands of years, people have used the radiant heat and light from the sun to cook their food and regulate the temperatures of shelters.  Today, solar cookers still are used to prepare a meal without the use of electricity.  Likewise, passive solar techniques can help you warm or cool your home through strategic placement of windows and landscaping.

  Solar renewable energy is on a recent upswing, as we may finally be realizing that fossil fuels are finite, and also contribute to global climate change.

  There are two primary types of solar panels:  photovoltaic (PV) panels generate clean electricity, and solar thermal panels heat water for household and commercial uses, without electricity or natural gas.  Solar water heaters are perhaps the most affordable and practical use of solar power.

  You might have seen solar panels on rooftops around town, but did you know that they are a great alternative to gas-powered generators for boats, recreational vehicles, construction sites and even military operations?

  When you consider the wide variety of uses of solar power, you may be asking why are we not tapping into this renewable resource more often?

  SunEdison Solar Projects in the United States to Be Funded by Wells Fargo

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  Private investment in solar power is necessary to support the industry and a transition to renewable energy resources which is necessary from both a cost and environmental standpoint.

  

  SunEdison solar projects get a boost from private investment in 2011

  Yesterday, Wells Fargo & Company announced that it would be investing up to $120 million in solar projects in the United States to be developed by SunEdison in the next 12 months.  The two companies entered into an agreement for financing a number of photovoltaic (PV) distributed generation projects this year.

  Barry Neal, head of Wells Fargo’s Environmental Finance Group, commented:

  “Wells Fargo is excited to continue our relationship with SunEdison and expand our commitment to grow the U.S. solar market,” said . “The solar projects developed by SunEdison will help businesses and public entities better control their electricity costs, while expanding the use of renewable energy throughout the U.S.”

  This is the second time Wells Fargo has invested in SunEdison solar projects.  In 2007, the company contributed over $200 million to help finance 150 solar panel projects in 8 states across the nation.  The parties will operate under a solar power purchase agreement (PPA) pursuant to which SunEdison will build and operates the systems and customers can buy the solar electricity produced at a cost less than grid-based power.

  In North America alone, SunEdison has helped create more than 400 solar projects totaling over 160MW in North America.  Wells Fargo has invested more than $8 billion in renewable energy projects.

  Costs and Benefits of Solar Power Compared to Other Energy Options

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  When it comes to solar power, many people are worried about the cost.  Whether you are installing solar panels on your roof, or your local utility is drawing on solar to reduce its reliance on fossil fuels, the bottom line is often described in dollars and cents.

  

  Solar Power Includes Many Benefits

  Sure, many of us are concerned about environmental impacts, but when it comes right down to it, one of the biggest concerns with respect to solar energy is how much it costs to generate renewable energy, as opposed to coal or gas.

  The one aspect you can control in this regard is to decide whether or not to install solar panels on your own home.  Otherwise, you are at the mercy of your utility company, and its decisions to invest in renewable energy options.

  It might help you to review the costs and benefits of solar power compared to other energy options:

  Benefits:

  • Locally generated clean energy
  • Low carbon emissions and greenhouse gases to help combat climate change.
  • Solar development can create thousands of green jobs
  • Solar projects may provide millions of dollars in tax revenues

  Costs:

  • Utility scale solar projects may have environmental impacts on threatened plant and animal species and historic or culturally sensitive Native American sites.
  • Solar power projects should not be built on public lands in pristine open desert ecosystem, but should instead be built on already disturbed lands, brownfield and former agricultural sites, and corporate rooftops.
  • Solar power development is paid for in part by taxpayer dollars which fund loan guarantees, grants and tax breaks
  • If technological advances render solar technology obsolete, it will be impossible to restore areas developed for renewable energy

  

  What impact does the cost of solar panels have?

  Solar energy continues to enjoy significant government subsidies, but it still costs more than fossil fuel and other sources of electricity generation.
  The International Energy Agency, a Paris-based, autonomous international energy policy advisory organization, publishes a semi-annual report on the projected costs of generating electricity. The agency looks at the total costs of different types of power plants over their lifetimes, along with the electricity generated during the same lifetime, to arrive at a cost per megawatt-hour figure.

  The results for IEA’s 2010 study of electricity generation costs for developed countries including the U.S. (range between 5 percent and 10 percent discount rate).

  Rates per megawatt hour:
  Nuclear: $59-$99
  Coal: $65-$80
  Gas: $86-$92
  Wind: $97-$137
  Solar (thermal): $136-$243
  Solar (photovoltaic): $215-$333

  How Cheap Can Solar Power Get?

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  

  Red, white and blue PV solar panels in the DOE SunShot program

  For those of us holding out for reduced prices on solar panels, you might be wondering… how cheap can solar power get?

  Well, brace yourselves for this amazing news.  The U.S. Department of Energy (USDOE) unveiled a new program this year that promises to reduce the price of solar energy to about $1 per watt b7 2017, and even further to 73 cents by 2030.  Through SunShot, the total cost of solar power can be reduced by more than 2/3 of current prices which average $3-4 per watt for fully installed solar panel arrays.

  According to the official website:

  Currently, PV solar panels cost about $1.48 per watt.  So, solar panel modules will have to drop at least 50 cents to reach the $1 per watt goal of SunShot.  In addition, installation and other costs will have to be slashed to a quarter of what they are today.

  The SunShot Initiative accelerates and advances existing DOE research efforts by refocusing its solar energy programs — valued at approximately $200 million per year — to make large-scale solar energy systems cost competitive without subsidies by the end of the decade.

  The DOE’s SunShot program helps reduce solar panel costs by focusing on the overall cost of an installed solar system, with an eye to improve efficiency of solar cells and also cut installations and permitting costs.  And when you think that the cost of solar panels has been drastically reduced since 1980 from over $21 per module to a mere $3-4 each, cheap solar power is something we should all be considering tapping into.

  

  Cheaper solar panels will help encourage more installations

  Cheap solar power is certainly worth our tax dollars, don’t you think?  The sooner we can get down to or below $1 per watt for solar energy, the better.

  What are your thoughts?  Please share below.

  A community solar garden in Colorado

  Thinking about installing solar panels on your home, but don’t have proper sunlight exposure?  Perhaps you want to share the costs with like-minded neighbors?  With a new renewable energy model, community solar gardens may be the answer.

  In Colorado, a new law allows the creation of “solar gardens,” which are photovolatic (PV) solar projects no larger than 2-megawatt (MW) with 10 or more subscribers within the same county.  Businesses, nonprofits and even utilities can create community solar gardens.  Operations must be handled by an organization solely in charge of the solar garden and its subscribers, somewhat like a special tax district.

  The idea is a blend of distributed generation (solar energy produced and utilized onsite) and utility scale solar power.  It allows property owners to efficiently use blocks of land to generate amounts of renewable energy that would be too great for one person, but enough to serve a small community.  In other words, community solar gardens are the happy medium between localized solar power and energy that is fed over the grid from solar power plants.

  Colorado was the first state to pass a law allowing creation of community solar gardens (CSGs).  Under its provisions, Colorado utilities must purchase at least 6 megawatts (MW) of electricity from operational community solar gardens.  According to Renewable Energy World, a recent release of the draft rules for CSGs “May open the floodgates, turning distributed solar power into democratic solar power.”

  If you’d like to learn more about community solar gardens, the Solar Gardens Institute, in partnership with the Colorado Renewable Energy Society, will hold a  SOLAR GARDEN SYMPOSIUM on May 6, 2011.  Installers and industry professionals are encouraged to attend tolearn more about off-site solar.

  Solar panels to be installed under a Power Purchase Agreement in Broomfield Colorado

  Have you heard of a solar power purchase agreement (also known as a PPA)?  These contracts are becoming a popular way by which to finance solar panels and enjoy the benefits of solar electricity without the upfront costs.  Some residential property owners have entered into PPAs, but often they are used by businesses, corporations and governments.

  The City of Broomfield, Colorado is one municipality that is giving its taxpayers a big break over the next 20 years.  The City estimates it will save nearly half a million dollars in operating costs due to a solar power purchase agreement with Lighthouse Solar.  According to Geoff Manchester, VP of Operations at Lighthouse Solar:

  “The big story is that the city paid nothing to get all the advantages of solar power.  And now they can budget around a fixed electricity cost for the next 20 years.”

  Under a PPA, the City only pays for the clean solar electricity generated by solar panels.  It doesn’t purchase the panels, maintain or even insure them.  Lighthouse Solar owns and operates the solar panel system.  Not only is the City’s monthly payment for solar energy generated lower than current grid-based electricity, but the amount will not rise at the same rate as utility hikes over the next 2 decades.

  The solar electricity production for the City of Broomfield will be approximately 588,720 kilowatt hours (kWh) annually.

  Solar powered electric vehicle recharging stations like these minimize grid impacts

  With more and more electric cars and hybrids expected to hit the market over the next few years, and gasoline prices continuing to rise, some are concerned about the impact of plug-in cars on the electrical grid.  Could we experience brown-outs or skyrocketing utility bills as a result?

  Using solar power for electric vehicles is probably the best bet to minimize the public’s concerns.  With solar panels installed on garages, parking lots, and even park and ride facilities, consumers can plug in their car and enjoy inexpensive recharging with solar electricity.   When solar power is used for electric vehicles, there is no grid impact.  In fact, solar panels will absorb UV light throughout the day to convert into solar electricity.  Even if your car is not plugged in, excess power generated by the system can be fed back into the grid, thereby lowering costs across the board for all consumers.

  

  Solar panel-covered carports provide clean electricity to recharge EVs

  A number of electric cars are already driving on roads and highways, including the Chevy Volt and Nissan Leaf.  More auto manufacturers are planning to release electric and plug-in hybrid electric vehicles over the next 2-3 years.  The worry is that infrastructure, including grid updates are not in place to handle the influx of battery-powered cars.

  Yet in markets in California and Washington State, lawmakers and industry leaders are ahead of the curve, encouraging and building solar powered garages and parking lots, as well as rapid charging stations that use solar panels along major thoroughfares.

  Using solar power for electric vehicles not only reduces loads on the grid, but also provides for a cleaner drive.  Critics of EVs claim that you are just exchanging one dirty fuel (gasoline) for another (coal or gas powered electricity).  Yet, cars that run on solar power are about as emissions-free as you can get!

  How to Lower the Cost of Installing Solar Panels

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  

  Lower the cost of solar panel installation

  Worried about how much you might have to spend to go solar?  You’re not alone!

  But if you learn how to lower the cost of installing solar panels, you can reduce your energy bills, and cut down on the upfront costs that are involved with going solar.

  A new report from SunRun to the U.S. Department of Energy establishes that the cost of installing solar panels can be cut by 50% or more, which can make solar energy much more affordable.

  SunRun is perhaps most well-known for its solar panel lease program, which allows consumers to lease a solar system from the manufacturer, pay reasonable, low-cost monthly installments and enjoy substantially lower electricity bills as a result.

  But a solar panel lease alone is not the complete answer.  To lower the cost of installing solar panels, land use permitting regulations must be streamlined across the board.  Applications, inspections, reviews and delays cost us all dearly.  In fact, researchers say that we can save about $.50 per watt by reducing red tape.

  In order to lower the cost of installing solar panels, most experts agree that standardizing the process surrounding permitting, interconnection and installation is necessary.  This is working well in Europe, and we need to implement the strategy here in the United States.  To break down the log-jam that can occur at the municipal permitting level, SolarTech has issued The Solar Challenge, which calls for solar installation to go from closing the deal to interconnection in 60 days.

  The overall cost of installing solar panels can be slashed by up to $1.00 per watt of energy!

  Solar Power in Texas

  Everything’s bigger in Texas!

  So, why hasn’t the Lone Star State taken better advantage of the ample sunshine that warms its sunny skies?

  Among Southern States, Texas is far from being a leader in solar development, but now solar power is going big in Texas!

  With new legislation proposed in House Bill 2961, called the Solar Generation Incentive Program, solar rebates for rooftop solar panels and commercial solar installations will help property owners afford solar power and make the change from coal and gas.

  The state funding under consideration would help about 50,000 homeowners and 1,000 businesses install solar panels this year alone!

  The new solar legislation should really jump-start the renewable energy industry in Texas.  According to the Star-Telegram, the following people are eligible for rebates: electric customers, qualified solar installers, remodelers, home builders, and  third-party owners of solar generator systems.  The incentives are in addition to federal tax credits up to 30% for solar.

  The Solar Generation Incentive Program in Texas would provide:

  • $2 per watt for distributed solar systems of 10 kilowatts (kW) or less at your home or business
  • $1.40 per watt for installed solar of 10 to 2,000 kW
  • $1 per watt for installed wholesale solar generation

  In addition to helping residents make the switch to solar energy, the new program would also create a number of green solar jobs in the state.  Steve Wiese, President of Texas REIA, observes:

  ”If we can develop solar energy in this state, we potentially can develop a manufacturing base that can employ people producing these [solar] products for out-of-state as well as in-state.”

  Talk about big, positive changes for the State of Texas!

  Jay B. explains that his 5 kilowatt (kW) solar panel system on his home will power a new electric car from Nissan.  For naysayers of electric vehicles who like to claim that they are just as “dirty” as cars with internal combustion engines, solar energy is clean and emissions free.  That means that an electric car powered by sunlight is as eco-friendly as it can get.

  The Nissan Drive Electric tour contest ends on April 30, 2011, in just a few weeks.  You can still enter if you live in the U.S., or just be sure to vote online for your favorite clip.

  Costs and Benefits of PV Solar Energy

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  

  Residential Solar PV Panels

  We hear a lot about how bad coal is, and now there are some serious concerns regarding nuclear energy as an option in the wake of the Japan Earthquake.  What about solar?  If you are considering this renewable resource, think about these costs and benefits of PV solar energy (photovoltaic, or electric solar).

  On the plus side, PV solar energy is:

  • Reliable. Once you determine how much sunlight hits your roof each year, it is relatively easy to predict how much energy you can generate with PV solar panels.  Unlike your utility, solar won’t subject you to rate hikes.  In fact, as the years pass, you’ll pay off your solar panel system and eventually get down to paying next to nothing for electricity.

  • Cheap. Instead of paying the electric company, pay yourself!  With lower costs, generous incentives and rebates, many homeowners can pay off the investment in PV solar energy within 5-10 years.  With net metering, you can turn back your meter and get credit on your bill for extra energy generated!

  • Safe/clean. Solar panels do not emit any greenhouse gases in operation, unlike coal or natural gas.  And, in contrast with nuclear power, they are very safe to operate.  Simply install and then enjoy solar electricity for years to come.

  On the other hand, there are some downsides to PV solar energy:

  • Inconsistency. You might be able to estimate your solar energy production over a longer period of time (months or years), but estimating how much will be produced on a daily basis is more difficult.  Not only that, but nightfall means that your solar panels will take a 10-12 hour break until daylight again.  If you have “banked” extra solar electricity during the day, you can get a credit on what you draw overnight, however.
  • Expensive Upfront.  Yes, you can save dramatically over the lifetime of your solar panels, but at the outset it can be difficult to invest in solar.  Solar panel leasing and property assessed clean energy loans (PACE) programs can help eliminate down payments, but not everyone is convinced that switching to solar pencils out.  At least not until grid parity is reached.
  • Property constraints.  Not all rooftops are ideal for installing PV solar panels.  If you don’t have southern exposure, or if you live in a woody, shady area, it is possible that not enough solar radiation will reach installed panels to generate ample electricity.

  Before you go solar, consider the costs and benefits of the renewable resource as it specifically applies to your home!

  Biggest Solar Panel Manufacturers in the World

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  

  Consider this list of big solar panel manufacturers

  While the biggest solar panel manufacturers in the world may not necessarily be the best, its still worth considering the list of the largest players in the solar power field worldwide.  We found this information on Solar Feeds, from Green World Investor.

  Before you invest in solar panels, do some of your own research and compare costs to quality, and also consider government incentives and rebates.

  Motech – The company which used to be a pure play cell producer has expanded into polysilicon,modules and wafers.  It is one of the oldest solar cell companies in Taiwan and faced tough times in 2008 post the GFC.TSMC owns a stake in this company.  The company bought a solar module facility in the US and is starting polysilicon production at its subsidiary AES Polysilicon.

  Suntech – Suntech was  the world’s biggest producer of solar panels in 2010 and was one the first companies to set up operations in China.Its example was followed by a host of other Chinese companies.Suntech has been slow to expand compared to the fast growing small companies in China and has lost marketshare to them.  It has started to vertically integrate in order to meet the low cost challenge from Trina and Yingli.Suntech makes one of the best quality Solar Panels in China.

  Yingli Green Energy - Yingli Green Energy is one of the oldest Chinese companies and is completely integrated from polysilicon.The company has been expanding rapidly and has one of the lowest cost structures in the industry.  Yingli Green Energy has been sponsoring Football in Europe and has started a new line of high efficiency “Panda” Solar Panels.  Yingli is the second biggest producer of Solar Panels in China.

  Trina Solar – Trina Solar is one of the lowest cost manufacturers of Solar Panels in the World right now and also sells it at a very low price.  This is the reason that the company in a span of few short years has managed to acquire a substantial  global marketshare.  The prices the solar panels being sold are around $340 per 200 watt module.Trina Solar.Like Yingli and Suntech,Trina Solar Panels are one the best quality in China.

  Hanwha Solar One - The Company which was recently acquired by South Korean Chemicals Giant Hanwha also makes one of the cheapest panels and sells it a very low price.  The quality is also quite good and with strong parentage behind it, the solar panels made by the company.  Again like Trina Solar, it has very low cost Chinese manufacturing capacity. The company was earlier known as Solarfun.

  Canadian Solar – The Company sells a wide variety of solar panels unlike other producers.The Solar Panel Selling Price is also quite cheap.   The Company is headquartered in Canada with factories in China and Ontario.  Canadian Solar is the 5th biggest producer of Solar Panels in China.

  Jinko Solar – Jinko Solar has shown the fastest growth rates in the Chinese Solar Panel Industry.  The company is expanding again to become one of the Top 5 Solar Panel Producers in China.  Jinko Solar like Trina and Yingli is vertically integrated and has one of the lowest cost solar panel production process.

  Solarworld - Solarworld is the Biggest German producer of solar panels, the company is one of the few to still have operations in Europe and USA.  The company has been battered by low cost competition. However Solarworld is strongly expanding in USA as growth slows down in Germany.  Solarworld is also entering the polysilicon sector through a JV with Qatar.Only Western company not to have a major factory in Asia.

  First Solar – First Solar is the only Solar Thin Film Manufacturer in the world and a benchmark for other thin film companies thinking of making it big.  The company was promoted by Wal-Mart promoters and has seen remarkable growth in the last few.This US based company uses Cadmium Tellurium (Cd-Te) Technology and  is the lowest cost panel producer in the world today if you don’t include any penalty for low efficiency.  Even if you penalize the Cd-Te Technology for its lower efficiency vis-a-vis the higher efficiency crystalline technology, First Solar is clearly the leader with a core cost of 74c/watt.  The company has a roadmap of  reducing the cost to 52c/watt by 2014 and given its track record it seems quite achievable.  There is little doubt about First Solar’s ability to survive and flourish due to its massive first mover advantage.

  Sharp – Sharp,the Japanese Zaibatsu known more for its Electronics Products is also the world’s No 1 Company in terms of Solar Module Revenues. Despite its leadership in c-Si Technology,i t has shifted focus to a-Si thin film due to higher costs.  Sharp has started shipping a-Si modules from its 1 GW capacity plant in Sakai. With its established distribution strengths and technological abilities in LCD Technology, Sharp is one company that can survive the c-Si onslaught.With most of the a-Si thin film competitors bankrupt or in a moribund state,Sharp can capitalize to completely capture this space.  However the cost structure of Sharp is not clearly known right now to make a clear call on how this will turn out. Also a 10% efficiency while decent for a-Si technology fall far short of the 13% claims by CIGS start-ups like Miasole.

  Sunpower - Sunpower produces the highest efficiency crystalline solar panels in the world.  This is a US company like First Solar and has a strong system installation business as well.  An offspring of Cypress Semiconductor,it faced tough times due to its higher costs.  However, it seems to be on a recovery path.  Failed to expand as rapidly as the Asians in 2010.

  Renewable Energy Corporation – It is Norwegian manufacturer of mainly polysilicon and wafers.It suffered like other Europeans from the declines in solar panel prices.Has moved manufacturing to Singapore to lower its cost.Fell down the rankings due to tough competition.However is completely integrated.

  Panasonic/Sanyo – Sanyo is the producer of high efficiency solar panels and like Sharp sells mostly in Japan and USA.  With buyout by Panasonic is looking to sell integrated energy  efficiency/energy storage/solar energy home solution.

  Solar Panel Array to be Built on Highest Plateau on Earth

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  

  The Tibetan Plateau will be home to a massive solar panel array

  If you got any closer to the sun, you’d be in outer space!  The highest place on earth (other than a mountaintop), the Tibetan Plateau, will soon be home to a solar panel array built by SunTech.

  Capturing intense sunlight – less filtered by the atmosphere than at lower levels – solar energy can be more efficiently absorbed and converted into solar electricity.  The Tibetan Plateau sits 4,000 meters above sea level and is situated between the Himalayan range and the Taklamakan Desert.  This makes the highest plateau on earth a prime spot for solar panels!

  SunTech’s 1o megawatt (MW) solar panel array on the Tibetan Plateau will generate over 20,000 megawatt-hours (MWh) of solar electricity for towns and villages in the remote region, including the Chek Kang village in Sangri County.

  Reliance on solar power will be more predictable and efficient than the current use of hydrolectric facilities, and should help Tibet achieve sustainable economic development.  Existing energy sources will not be abandoned, however – just supplemented with power from the solar panel array on the Tibetan Plateau.

  A sure sign of the region’s excitement supporting SunTech’s solar panel installation is the new SunTech flag that now flies on Mount Everest!

  Solar Panels for Homes in Southern California

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  Looking to save energy with a new home purchase?  Solar panels on homes in Southern California come standard in ten KB Home developments.

  

  KB Homes in Southern California will be constructed with solar panels

  Rooftop solar panels are becoming more and more commonplace and are often requested as upgrades by purchasers of new construction.  In the KB Home developments, solar panels give buyers an automatic “cash back,” in energy savings at 30% or more.  Not only that, but resale value of these homes will be higher, as well.  For every $1 in electricity costs saved, home values are boosted by $20.  Even a modest $300 annual savings means $6000 in home equity!

  The solar panels on homes in Southern California is a “test market” for KB Home.  If buyers love the – FREE – solar panel upgrade, the company will expand the program into other regions.

  KB Home was voted “Most Admired Homebuilder” in 2006, 2008 and 2009.  The company builds homes across the southern states in the U.S. from California to South Carolina. The rooftop solar panel system installed on homes in Southern California are manufactured by SunPower Corp.  The PV solar panels panels can achieve more than 24.2% efficiency.

  Would you buy a new home with solar panels as a standard feature?

  Solar Windows to Be Installed on Willis Tower

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  Exciting news in the world of building integrated photovoltaics!  Solar windows will be installed on Willis Tower (formerly known as Sears Tower) to generate clean solar electricity and reduce the operating costs of the building.

  

  Solar windows to be installed at Willis Tower

  Recently, Pythagoras Solar, announced that it has been chosen to collaborate on a pilot project to help Willis Tower realize its renewable energy and energy efficiency improvement goals.  South-facing windows on the skyscraper’s 56th floor will be transformed into solar windows that can generate over 2 megawatts (MW) of solar energy.

  John Huston, Executive VP of American Landmark Properties which co-owns Willis Tower commented:

  “We are excited to launch this pilot with Pythagoras Solar’s leading-edge solar window solutions as a test for not only the energy savings that can be achieved, but the potential they represent to actually generate power through the sun.”

  Just think of the potential if all skyscrapers in the world also installed solar windows, following the lead of Willis Tower!  Its now possible, given solar technology like that of Pythagoras Solar, which is the first company to offer a fully integrated photovoltaic glass unit (PVGU) that addresses the need for simultaneous benefits of energy efficiency and high power density, while also offering architectural design benefits to increase real estate value and advance Net Zero Energy Buildings (NZB).

  Increase in Solar Power Following the Japan Earthquake

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  Two things have resulted in an increase in solar power following the Japan Earthquake of a magnitude 9.0.  The first is the scare surrounding its nuclear reactors, which has left many looking to rely on cleaner renewable energy resources, and the second is the need for reliable power when grid systems are down.  Mobile solar power to charge cell phones, GPS devices and even refrigerators can literally be the difference between life and death when power is out.

  

  Solar Poweron the uprise following the Japan Earthquake

  While Japan struggles to recover after the disaster, other countries are taking note and hoping to lay the groundwork for safer renewable energy options, beyond nuclear.  The State of California, in particular is looking closely at two of its own operating nuclear reactors – Diablo Canyon and San Onofre – which may be vulnerable to earthquakes.

  Quite simply, the Japan Earthquake may be causing a major shift in the way we approach alternative energy in the future.  In fact, some experts believe that nuclear power will likely play a smaller role in the future energy market, while solar and wind energy are much more secure, safer and easy to distribute.  But others, may still be placing stock in nuclear, despite fears.

  Finally, the location of the earthquake will impact solar energy in general.  Japan currently makes up a quarter of the world’s solar production.  In the days following the natural disaster, the following plants shut down production of solar panels:  Sanyo, Panasonic, the Kyocera Corp. and Sharp.  Even when the workers return to the factories, the power grid still cannot transport clean solar electricity to the people that need it most.

  

  More solar cities in Japan in the future?

  Overall, the governments of Japan, China, France, Italy and Germany may add to the solar energy shares in their renewable energy portfolios in the coming months.  At the same time, plans for new nuclear power plants around the world are being scrapped.  All this momentum could result in promotion of solar power, and a cleaner, safer future.  If there is a single silver lining from the terrible Japan Earthquake tragedy, perhaps this foundation of hope is it.

  Solar Power More Efficient Than Wind Energy

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  Would you be surprised if I told you that solar power is more efficient than wind energy?  After all, this is a solar blog!   Most of us have driven past giant wind farms of slowly turning turbines or a utility scale solar farm with rows and rows of solar panels.

  Which one is better at generating electricity?  And why?

  

  Solar vs. Wind? Solar wins!

  You are not the only one wondering about the comparative efficiencies of both solar and wind.  In fact, in my home state of Washington in the Pacific Northwest, researchers at Inland Power and Light conducted an experiment pitting solar vs. wind, for title of most efficient renewable resource.

  Admittedly, the experiment was somewhat imprecise.  They used a single 35-foot wind turbine against a solar panel array, both of which were capable of generating the same amount of electricity under perfect conditions (and, coincidentally, each of which cost $22,000).  And the results?  Drum roll please….

  The solar panels generated 5 times the power of the wind turbine!  The reasons were primarily due to the fact that wind power is only effective at breezes of 3-12 miles per hour.  Stronger gusts actually prevent wind turbines from capturing the energy because they are designed to brake to prevent the gearbox/hub from being damaged.  While solar panels can suffer from decreased efficiency on overcast days, they are still able to generate some power.

  Turns out others have conducted their own solar vs. wind experiments, too (or have at least debated the pros and cons of each):

  Do you have direct experience with both solar power and wind energy?  Please share your thoughts about their comparisons below.

  Greenerator Combines Solar Panels and Wind Turbines to Generate Clean Electricity

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  One of my favorite things to blog about here is solar gadgets.  There is nothing like generating clean solar electricity to power your home or help cut down your power bills.

  We found this cool, artistic “Greenerator” recently, which combines solar panels and wind turbines to generate clean electricity right from your deck or balcony:

  

  The Greenerator combines solar panels and a small wind turbine

  The concept is the creation of industrial designer Jonathan Globerson and has been seen on Discovery News.  The balcony-based solar collector/wind turbine generates can generate enough clean energy to cut about 6% off of your electricity bill.

  Consider this video:

  Love these cool solar gadget inventions that can reduce carbon emissions while saving energy and money!

  Hopefully the Greenerator will soon be available for the public to use and enjoy.

  Using Net Metering with Solar Panels

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  Are you familiar with the term “net metering“?  You should be!  Did you know that renewable energy systems such as residential solar panels and wind turbines can allow you to offset your electricity bill?

  

  Depiction of using net metering with solar panels

  When sunlight is bright or winds are brisk, you may generate more electricity than you use.  In these cases, the extra energy is sent back into the grid for others to use, and you get a credit for the times during which you need to draw on grid-based electricity (i.e. overnight).  You can literally turn your meter backward during these times.  This is called net metering, and its how people can live on solar energy, even when the sun is not shining.

  Grid-connected solar power and net metering benefits more than just the customer.  Utilities love having you generate additional renewable electricity to help off-set peak demands, such as when its sunny and hot and everyone wants to crank the A/C.  That’s part of the reason they reward solar homes with net metering credits.

  Using net metering with solar panels also helps the Earth.  Renewable sources defray pollution, minimize use of fossil fuels, cut your carbon footprint and can help address global climate change.

  With more states and utilities expanding their net metering programs, installation of solar panels and other renewable energy systems will be encouraged.

  Homes with Solar Panels Gaining Ground in the Real Estate Market

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  Take a look at this picture, and then tell me whether you’d buy a home with solar panels:

  

  Solar panels are becoming a hot addition to real estate

  Yes, I agree.  Solar panels are not necessarily the most attractive feature of this otherwise beautiful home.  However, did you know that homes with solar panels sell faster than those without?  That’s right, according to a 2010 study by  NREL (National Renewable Energy Lab), homes with solar panels are gaining ground in the real estate market.  Not only do solar powered homes sell faster, but they get nearly 20% more in asking price, as well.

  I’ll bet those solar panels are looking a lot more attractive now, aren’t they?

  The value solar panels add to a home are worth the added cost.  Experts agree that for every $1 you save in annual electricity bills, your house is worth $20 more.  So, if you shave off $500 a year by adding a home solar panel system, your home could be worth $10,000 more.  All of a sudden the $20,000 investment in solar doesn’t seem like as much of a burden.

  

  Homes with solar panels are becoming more visible as well as more valuable

  But getting back to the marketability of homes with solar panels, the trend is definitely on the rise.  Three reasons come to mind: (1) the desire for energy security; (2) dropping solar costs and generous government incentives/rebates; and (3) increasing visibility of rooftop solar panels as more property owners opt to install them.  With respect to this third factor, clear trends and concentrations of residential solar installations have developed in California and New Jersey, both of which offer strong solar incentives.

  But perhaps one of the most compelling reasons that homes with solar panels are gaining ground in the real estate market is that the idea of low or no monthly electricity bills help these properties stand out in the down economy among a glut of housing inventory. The average U.S. homeowner spends about $1200 on grid power per year (about $100 a month), so when a real estate agent mentions a home has an electrical bill of $2.20 per month, that becomes a selling point on par with outdoor fireplaces, hot tubs, and low taxes.

  Look for more solar real estate trends to develop in 2011.  If you’re thinking about this renewable energy resource, now’s the time to go with solar power for your home.

  Solar Roofing Shingles: Information and Cost

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  Have you heard about solar roofing shingles?  Instead of regular asphalt shingles, you can literally cover your roof with materials that can generate free solar electricity while providing shelter.  Solar shingles look like “regular” roofing materials, but include photovoltaic (PV) film covering that can absorb sunlight and convert it to solar power you can use inside your home.

  

  Solar roofing shingles are sleek and energy efficient

  Solar roofing shingles are becoming a popular option for homeowners that want to go solar because they have a low profile and do not require roof penetrations or heavy brackets for installation.  Some people have reported better success getting approval from local governments and homeowners associations for solar shingles, compared with solar panels, because they are more attractive.

  Solar roofing shingles can generate enough electricity to cover 60% of your annual electricity bills.  And, when you consider that for every $1 saved in utility bills, your home increases in value by $20, the return on investment for this home improvement will quickly be realized.  Just think – if you can save even $300 a year, that is a $6000 equity boost for you and your home.

  The average cost of a solar roofing shingles project (materials and installation) is $15,000-20,000.  Government incentives and rebates can be applied to reduce the cost, and don’t forget to factor in your boost in home value.

  

  Solar roof shingles installed

  Solar shingles last longer than regular roofing tiles, which can extend the life of your roof.  Because they lie flat against the surface, they’re one of several types of building integrated photovoltaics – literally, solar generating building materials.  Don’t worry about losing your specialized solar shingles in storms or high winds.  They can withstand gusts up to 80 miles per hour.

  Solar roofing shingles are installed just like regular roof tiles.  They are layered onto the roof with at least 5 inches of the PV film-covered surface exposed.  Wiring is then connected by an electrician so that you can start drawing on free solar electricity.  Depending on your electrical utility, you may be able to get feed-in credits for sending extra solar power into the grid.

  If you are considering solar shingles to help cut your energy bills and your carbon footprint, you’re making a smart investment in the future!

  Gas Prices to Drive Solar Power Demand

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  Rising gas prices are causing a pinch at more than just the gas pump.  Homeowners are also directly affected when fuel costs rise, as it becomes more expensive to heat and cool their homes.  Experts expect the impact of the current upward trend in gas prices to drive solar power demand.

  

  In the past, the solar industry has benefited from inflated gas prices.  Now, with solar demand already up thanks to the cost of solar panels going down and government incentives/rebates, more homeowners have already installed solar on their rooftops.  As other people look around, solar becomes the obvious answer to the issue of crushing energy costs.

  There is good precedence for this prediction.  In July 2008, when oil reached $147/barrel, solar power consultants received numerous calls requesting information on renewable energy.  Today, its more than just a question of cost.  Many Americans desire to gain control over future utility rate hikes and to cut reliance on foreign oil for safety and security concerns.

  In addition to more homeowners considering solar panels for their rooftops, we expect to see more electric vehicles in garages.  At the 2011 North American International Auto Show, EVs and PHEVs were the hottest cars on the showroom floor.   Consumers are snapping up the new electric cars as fast as automakers can create them, and some options include solar panels to power A/C.

  With solar panels on residential rooftops or garages, some people will literally be driving on solar energy…. and smiling big as they drive past the gas stations demanding over $4/gallon!

  Solar Power from Space Still Off in the Distance

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  For decades, there has been a “space race” of sorts going on behind the scenes.  Researchers and scientists have been working to develop a way to effectively and efficiently harness solar energy straight from space.  Yet, even as solar technology advances here on Earth, solar power from space is still off in the distance.

  

  Is solar power from space on the horizon?

  Blame a lack of funding, rather than innovation.  The United States, Europe and Japan have developed projects that would beam solar power from space, where the sun is constantly shining and is not filtered by the atmosphere or weather patterns.  However, in order to test and implement them requires a great deal of capital that governments simply do not have.

  According to the Japan Aerospace Exploration Agency (JAXA):

  “High-accuracy beam control technologies both for microwave and laser power transmission, construction of large space structures (kilometer-scale), and low-cost space transportation are the major challenges.”

  Not only is expense a major hurdling block, but there is not consensus on the best way to transmit the collected solar power back to Earth.  Solaren Corp. will use microwaves to supply solar power for utility giant Pacific Gas & Electric by 2016, but laser beams are the preferred method of Europe’s EADS Astrium.

  

  Solar energy above the atmosphere can be transmitted to Earth

  Once we finally agree on a method to transmit solar power from space, addressing the… um… “sky high” costs is the next step.   Yet, a recent cost analysis by JAXA and another Japanese space agency, the Institute for Unmanned Space Experiment Free Flyer, determined that space-based solar power might eventually cost only 10 to 20 cents per kilowatt hour (kWh), which would make it competitive with fossil fuels.

  But we’re talking at least 20 years from now, according to the agency.  Don’t expect a viable space solar power system until the 2030s at the earliest.

  Solar Hot Water Cost: Truth and Fiction

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  Solar hot water is an easy , relatively inexpensive way for homeowners and businesses to reduce their utility bills and carbon footprint.  Heating water for residential and commercial uses (think hotels, breweries, nurseries and car washes) requires a great deal of power, which normally comes in the form of grid-based electricity or natural gas.  With a solar hot water system, radiant energy from the sun warms the water instead so that your hot water is basically free.

  

  Residential solar hot water panels

  Not that many people are familiar with solar hot water.  So, here’s a quick list of the truths and fictions regarding the cost of innovative renewable energy systems:

  1.  Solar Power is too Expensive.  Compared to photovoltaic (PV) electric solar panels, most residential solar hot water systems are about $10,000 cheaper.  The cost of solar hot water systems for a home is between $7,000-9,000, but this is before federal, state and utility incentives and other rebates.  Here in Oregon, where I live, the State offers a $1,500 tax incentive, which is on top of the 30% tax incentive from the federal government.  In addition, utilities may throw in financial incentives, up to $1,200 of the cost.  Total all of these credits up, and you’ll save as much as $5,000 on a solar hot water system!

  2. Solar Panel Systems Cost too Much to Maintain.   Actually, most solar hot water systems (and PV panels) basically operate without any intervention for years.  In other words, install and forget about it!

  

  What will a solar hot water system cost you?

  3.  The Return on Investment for Solar Power is not Worth It.  Want to know what your annual return on investment (ROI) for a solar hot water system might be?

  Experts say the calculation is easy.  Simply multiply the size of your household by $100.  A family of 6 like mine will save $600 a year on energy costs.  On a $4,000 system (the cost after applying incentives above), that is a 15% ROI in the first year alone!

  Talk about a wise investment!

  Should You Install DIY Solar Panels?

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  There are a number of reasons to consider residential solar panels for your home: reduced electricity bills, reliable power in the case of an outage, and even a smaller carbon footprint.  But many people looking to save money on the cost of solar decide to install DIY solar panels instead of paying for professional services.

  

  DIY solar panels offer varying results

  How much can you save?  Are you the kind of person that enjoys DIY home improvement projects?  Before you get out the ladder and drill bit, let’s consider the risks and benefits of installing DIY solar panels.

  Benefits:

  • Cost savings on solar panels.  Whether you go with a DIY solar panel kit, or even create your own solar panels with materials, you’ll be able to save hundreds if not thousands of dollars over a professional installation.
  • Flexibility in the type, function and location of the solar array.  Order 2-3 solar panels and decide if they work.  Need more juice, get another one.  If you are 100% in charge of your own solar energy generation, you can make revisions to the system at any time.
  • Satisfaction in completing the project yourself. When you undertake a DIY solar panel installation, you can take pride in completing the system and may be better invested in its maintenance and efficient power generation.

  We love this video that explains how easy and cheap DIY solar panels can be:

  Risks:

  • No warranty for installation of DIY solar panels.  If you purchase commercial solar panels, you might have a product warranty, but if you make errors in the installation, you have no one to turn to but yourself!
  • No assistance in applying for rebates or tax credits.  Professional companies will usually help you maximize savings under various federal, state or local programs.  DIY applies to this part of the equation too!
  • No assistance in securing land use and/or construction permits.  Don’t forget that your local city or county probably has regulations governing installation of solar panels.  Homeowners Associations do too.  Professionals can often secure these approvals quickly and efficiently, but it might take you more time to do so.
  • Possibility of damage to the panels or incorrect installation.  Even DIY solar panels are relatively expensive.  You might want to protect your investment by bringing in professional installers, or at least someone in the construction industry to help!  Don’t forget wiring, which may require the help of an electrician.

  

  DIY solar panels can save a lot of money when they are done right

  Want to switch to solar energy, but worried about the high cost?  You are not alone.

  Many homeowners consider the benefits of solar power, including lower electricity bills, guarding against utility rate hikes, reliability in the case of power outages and more.  But, with the average residential PV solar panel array system costing at least $15,000, the price is often a deterrent.

  There’s plenty of good news to consider, however.  Solar panel prices have dropped by more than 50% in the last few years, and a trio of federal, state and often local incentives can further cut the price from 30%-80%.

  Here’s five easy ways to lower the cost of solar panels for your home or small business:

  1.  Do an energy audit first.  Figure out how much electricity you are already using and where you can save electricity.  Wash your laundry in cold.  Update to Energy Star appliances.  Turn off and unplug items before you leave.  Adjust your thermostat for overnight and during the day when no one is home.  If you use less electricity, you may not need as many solar panels as you might think!

  2.  Assess the slope and direction of your roof and clear vegetation away.  Solar panels are much less efficient when they are shaded, even if only a little bit.  Make sure that you have a south-facing roof slope at an angle that can maximize absorption of UV light.  Many solar panel companies will come to your property to do this assessment for free.

  3.  Consider negotiating a group discount.  There are companies like One Block Off the Grid (1BOG) that work with solar panel manufacturers to get cheaper solar arrays when more than one person in your neighborhood or city joins you in going solar.  You don’t have to personally know the other people, or ask them yourself.  Simply go to the website, type in your zip code and you’ll be connected with other people in your region with whom you might benefit in scoring a discount rate on solar panels.

  4.  Maximize solar incentives.  Between rebates and tax credits, the government would love to see us switching to renewable energy.  Research the incentives in your state first – some have new programs, but in other states, solar funds are running out.  Many solar installers and manufacturers will help you prepare the paperwork as part of the cost of their services. But when it comes to solar tax credits, talk to a CPA.

  

  Save money on your solar panels

  5.  Lease solar panels instead of purchasing them.  A solar panel lease is quickly becoming one of the easiest ways to go solar with little or no money down.  The manufacturer installs, owns, maintains and often insures the panels.  You pay a monthly fee – less than your current electricity bill – and enjoy the benefits of solar power, including fixed cost for power over the term of the lease (usually 15-25 years).  Solar leases are also usually transferable if you sell your property.   As with any legal document, be sure to carefully review its terms before signing!

  Now that you know these easy ways to lower the cost of solar panels, why not start taking steps to make the switch?

  Tags:    [edit]

  

  $3 million saved in electricity with a solar panel system will pay for 6 million meals

  When it comes to community service organizations like Second Harvest Food Bank, operations are often lean in order to funnel as many resources back to the people that need them most.  So, we were thrilled to hear about a new solar power system for Second Harvest in San Jose, California.  A rooftop solar panel installation of a 230 kW photovoltaic (PV) system includes 1100 solar modules which will generate enough free solar electricity to save the food bank $3 million over 25 years.

  $3 million is pretty impressive, but consider this: the cash saved by the organization will pay for an additional 6 million meals for deserving families in the community!

  

  Solar panels installed on the Second Harvest Food Bank rooftop

  The solar power system was installed by DRI Energy, which donated its services, on the 1.25 acre roof of Second Harvest Food Bank.  Payment for the rooftop solar panels was helped through a generous donation by Cypress Semiconductor Corp. and the donation of high-efficiency solar modules by SunPower Corp.

  The CEO of Second Harvest Food Bank, Kathryn Jackson, spoke about the new solar power system:

  “Second Harvest’s solar installation was made very easy by virtue of the care and professionalism of the DRI Energy team. DRI Energy was responsive to our questions, thoughtful in terms of planning the installation and flawless in terms of execution.  DRI Energy staff went out of their way to accommodate our needs throughout the process. We can’t speak highly enough of DRI Energy and the job that their team of professionals did on behalf of the food bank.”

  On the other hand, DRI Energy was equally excited about lending a clean energy hand to the Second Harvest Food Bank.  Steve Kelley, Executive VP commented:

  “Our core values include working with integrity and doing what we say we will do in the safest way possible.  Helping Second Harvest Food Bank achieve savings of over $3 million is what our company commitment is all about.”

  Clean, green projects like these are where communities can really shine!

  Solar Panel Efficiency Increased with Solar Pole Tracker

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  Although there can hardly be any debate that we should switch to renewable resources, there are two main concerns with transitioning to solar power.   First, is the cost of solar technology.  From solar panels to full-fledged solar farms, even with the recent drop in solar panel prices, its still more expensive than fossil-fuel power (using a direct economic cost comparison).  The second major concern is solar efficiency – in other words, the rate at which energy from the sun can be converted to usable electricity or other power.

  

  Solar Pole Tracker uses GPS technology to increase solar panels efficiency

  Now, solar panel efficiency is increased with the solar pole tracker.  This new technology helps optimize the amount of energy absorbed by solar panels by tracking the sun’s path across the sky during the day.  The solar pole tracker has been developed by Advanced Technology & Research Corp. with help of a $1.1 million grant last year from the Maryland Energy Administration.

  The solar pole tracker is no ordinary heliotropic device.  It uses a GPS controller to help panels follow the sun throughout the day, increasing solar panel efficiency by up to 30%.  Now that the solar technology has been developed, the company is aiming to sell them to government agencies and private businesses.  Solar pole trackers could be affixed to light and utility fixtures to maximize solar powered lighting and signage.

  At only $700-$1760, solar pole tracker devices will pay for themselves in 5 years or less, including renewable energy tax credits and net metering sales of extra electricity sold back into the grid.

  New solar panels at Knouse Foods Peach Glen facility

  More than 19,000 solar panels have been installed to generate solar power for the Knouse Foods manufacturing facility in Peach Glen, Pennsylvania.  The grower-owned cooperative makes Musselman’s Apple Sauce and Lucky Leaf Pie Filling, using fruit harvested from more than 3.3 million trees.  Now, its harvesting its own clean solar energy with the panels that are owned and operated by the company, as well.

  Knouse Foods’ solar panels will save significant amounts of CO2 from its operations.  More than 4 million kilowatt-hours (kWh) will be produced by the renewable energy resource, which is enough to power about 400 homes each year.  And its not the first sustainability step the company has made.  In fact, for more than 60 years, the cooperative has been focused on maintaining a healthy environment.  Its not only good for its bottom line, but also helps the growers produce high quality fruit for Knouse Foods’ products.

  In addition to solar power, the company has made a change to use lighter weight packaging to reduce fuel costs for transport, and also employs recycled materials in its packaging.  Knouse Foods also works to improve water quality and has adopted conservation measures to save 60,000 gallons per day in its operations.

  Another important piece of the sustainability program is the reduction in trash by 80-90% each year.  This includes making sure that its fruit doesn’t end up in landfills where it would decompose and release methane into the air.  Instead, apple pieces are sent to cider mills for juice pressing, or are passed along to farms for cattle feed.

  Knouse Foods has been presented with a number of awards for its responsible and sustainable business practices, including a Pennsylvania DEP Commercial Recycling Award, PA Governor’s Waste Minimization Award, WV DEP Environmental Stewardship Award, PA House of Representatives Citation, an Adams County (PA) Environmental Stewardship Award, and a PA Fish Commission Award.

  Solar Panels Made in America: AET

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  Recent news about the third largest solar panel manufacturer in the U.S. moving to China has had government officials and economists worried.  After all, President Obama is counting on green jobs to help lead us out of the recession, as well as cut our dependence on foreign oil.

  

  President Obama examines manufacturing of solar panels (image from whitehouse.gov)

  Perhaps we can take a page from Alternate Energy Technologies!  Its solar panels are made in America, and don’t rely on any foreign parts, either.  As noted in the Florida Times-Union, the Jacksonville, Florida company is creating all-American solar panels:

  “The company does not purchase anything from foreign suppliers, Byrom says. Its 60 workers bring in raw materials and manufacture everything in its 67,000-square-foot facility. Byrom said that makes AET one-of-a-kind in the United States, because other U.S. solar manufacturers are really just assembly operations that put together components fabricated in foreign factories.”

  The nearly 25-year old company manufacturers solar thermal panels, used for solar hot water heating systems.  These work by using radiant energy from the sun to warm water, which is fed into specialized solar hot water tanks.  While the U.S. was slow to catch onto the renewable energy bandwagon, AET has been serving areas like the Caribbean which often lack connection to the electric grid.  Today, AET’s business is 75% from the U.S., with the rest from foreign countries.

  Getting back to green jobs…. AET’s success in manufacturing solar panels in America is leading to plans for another, larger facility in Green Cove.  The expansion will more than double its workforce!

  According to President and CEO, Billy Byron, solar panels made in America is unique:

  “Everything is American-made. We’re very proud of that,” he said. “We are the only complete manufacturer in the United States.”

  Green jobs right here in the U.S.A.?  Sounds like a win-win for AET and the American people.

  Solar Panel Efficiency Increase of 300%

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  Two of the things solar panels are most criticized for are price and efficiency.  People grumble about the cost of solar panels and their relatively low conversion rate – how much energy from the sun can be turned into usable electricity.

  

  Photonics can increase solar panel efficiency by 300%

  Over the last few years, the cost of solar has dropped dramatically.  Now, there is news of a potential solar panel efficiency increase of 300%.  Researchers at HyperSolar have developed a film that can move certain light spectra to increase the conversion rate (and thus efficiency) of solar panels.

  The solar technology, which uses photonics, also has the promise of further cutting the solar panel installation costs in half, from already reduced figures.  Developed in the U.S., cutting edge renewable energy tech like this is important to keep the country as an energy leader.

  Demand for cheap and efficient solar panels is rising as installations are increasing worldwide.  Projections estimate that the 16 gigawatts of solar power that have already been installed globally will increase to 1,800 gigawatts over the next 2 decades!

  Solar Powered Refrigerator

  To those of us that live in the Western world, a solar powered refrigerator might sound like a cool, interesting gadget.  Yet, for people in remote, Third World regions, the ability to chill foods and medicines to appropriate temperatures without the necessity of being connected to the grid could save their lives.

  The solar powered refrigerator shown to the left was developed by the engineering firm True Energy and runs on”Sure Chill Technology.”  With daytime temperatures often reaching over 90 degrees F, Sure Chill can items at a safe, cool temperature (39-43 degrees F), using either solar power or grid-based electricity, depending on location and needs.

  Once the solar powered refrigerator reaches its desired temperature, it can go without any power or electricity for up to 10 days, without warming up.  With a high-density polyurethane foam as insulation and a phase change material that can store energy until needed.  The system responds to rising temperatures by kicking in to cool down the interior.

  Unicef and the World Health Organization (WHO) are using the solar-powered refrigerator to store vaccinations that need to be kept cool in remote areas of Africa.

  Solar Panels: Tame or Toxic?

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  

  Are solar panels tame or toxic?

  As the need for renewable energy resources increases, the debate over environmental impacts also continues.  One of the most contested questions concerns solar panels: tame or toxic?

  When you use solar electricity, you can reduce or eliminate your reliance on coal-based power.  In that regard, solar panels have a zero carbon footprint.  But photovoltaic (PV) solar modules could still be harmful to the environment.

  The National Renewable Energy Laboratory (NREL) has calculated that the average PV polycrystalline module will generate enough clean solar power in about four years to offset the energy required to manufacture it.  In fact, over the 30 year life expectancy of a solar module, about  90% of the energy generated will be pollution free.

  But what about the materials that go into solar panels?  PV modules use silicon, which is abundant and easy to harvest from the Earth’s surface.  Minimal environmental impacts result from this process, but when silicon is purified and crystallized, energy is required.  Also, cutting the wafers, processing them into cells and assembling solar panels is energy-intensive.  At this point, solar cells are not recyclable, but the industry is working to change that in the near future.

  Beyond the energy required to create solar panels, chemicals used in manufacturing are handled and disposed of in accordance with EPA regulations.  Overall, solar manufacturers have worked to make production safer.

  Remember that reliance on solar power is cleaner than other types of electricity.  Residential solar panel systems generally save the equivalent of 12 barrels of oil per year, per home.  If you could reduce your carbon footprint by 10,000 pounds annually, or drive your car 7,000 fewer miles, wouldn’t you do so?

  Cool Solar Shade at Chase Field in Arizona

  The sun shines brightly (and often hot) in Arizona.  But if you are heading to a game at Chase Field to see the Diamondbacks, you’ll love the new solar shade that not only provides cover, but also generates clean solar electricity.

  The solar shade (shown to the left) will cover 17,280 square feet above the plaza area near the ballpark’s western entrances and ticket booths.  Construction began this week and will be fully installed by May 2011.

  Solar panels will generate about 75 kilowatts (kW) of solar power for the stadium.  The installation is the result of a partnership between the Arizona Diamondbacks, Maricopa County Stadium District and APS.  The solar shade structure will generate electricity for about 20 years, some of which will be fed to electric vehicle charging stations at the ballpark.

  According to the Diamondbacks President and CEO, Derrick Hall:

  “The solar structure will not only further distinguish the D-backs’ green initiatives among professional sports teams, but it will also provide needed shading near the ballpark to enhance our fan experience during the hot summer months. This innovative project will be on display when baseball fans from around the world visit downtown Phoenix in July to attend the All-Star Game at Chase Field.”

  Fans that visit Chase Field, as well as the general public, can learn about the benefits of solar power.  The solar shade project will include educational exhibits on renewable energy, energy efficiency, electric vehicles and recycling.

  Chicken soup may be good for the soul, but now it can help the environment too!

  Campbell Soup Company announced this week that it will run on solar power at its Napoleon, Ohio plant.   Campbell’s Soup has entered a power purchase agreement with BNB Napoleon Solar for construction of a nearly 10 megawatt (MW) solar farm on a 24-acre parcel of property.

  

  Campbell Soup Company goes solar

  The PV solar panels will generate enough electricity to offset 15% of the plant’s power requirements, which will save more than $4 million over the life of the 20-year agreement.  The carbon savings from this reduction of emissions is the equivalent of taking 2,000 vehicles off the road each year.  The Campbell Soup Company solar power farm will include about 24,000 solar panels from SunPower, including a tracking system which follows the sun across the sky and increases the panels’ efficiency.

  In addition to significant energy and money savings, the solar power project will create about 200 green jobs in Ohio.

  According to the company’s press release, Campbell Soup has committed to reducing its overall environmental impact by half, including its water usage and carbon emissions.  Its 2010 corporate social responsibility report indicates that Campbells recycled more than 84% of the waste it generated, and also invested over $6 million in sustainability projects.

  Solar Wind Bridge Envisioned for Italy

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  

  Solar wind bridge - amazing design and technology

  At the intersection of design, architecture and renewable energy is a new solar wind bridge envisioned for Italy.  The futuristic road span is the dream of three Italian designers, Francesco Colarossi, Giovanna Saracino and Luisa Saracino.  Intended to capture energy from the wind gusts that often blow through mountainous regions, as well from as solar power striking the road’s surface, the solar wind bridge could generate enough electricity to power about 15,000 homes.

  The design recently took second place at Solar Park Works – Solar Highway competition.  The contest called for design entries for a modernized section of highway between Bagnera and Scilla in Italy.

  These photographs are so amazing:

  

  Solar wind bridge in Italy (aerial view)

  Solar panels on the asphalt surface could generate 11.2 million kilowatt-hours (kWh) each year.  The 26 wind turbines engineered into the span of the bridge (using an abandoned viaduct) will be able to produce 36 million kWh annually.  As noted above, this power from this single bridge span could run 15,000 homes.

  The green elements of this bridge also include dedicated areas for solar greenhouses in which produce can be grown and sold right there on the span!  In fact, the re-purposed viaduct would basically be transformed into a public park/viewpoint.  And a significant tourism draw, as well!

  We cannot wait for this inventive solar architectural design to move from the drawing board to the scenic highway stretches in Italy.

  Solar Growth in China: Too Competitive for the United States?

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  Last month, news that the third largest solar manufacturer in the United States was leaving to build solar panels in China was stunning, but was it really all that surprising?  Solar growth in China continues to eclipse renewable energy manufacturing here in the USA, despite government incentives to spur green jobs and investment in solar energy.

  

  Can the U.S. compete with China with respect to solar manufacturing?

  Is China too competitive for the United States when it comes to solar power?  What is it that China has that we don’t?

  Perhaps most importantly, the Chinese government is significantly more generous with financial support for the solar industry and private investment is not hindered by project-slowing red tape that trips up solar power plant plans here in the U.S.

  Because solar energy has not achieved grid parity with coal and other fossil-fuel based electricity, it needs an edge to help it be competitive in the marketplace.  Federal and state incentives help, but private investors also need assurance that putting their money in solar is a wise move.

  For the United States to compete with China with respect to solar manufacturing and technology, renewable energy goals should be increased to boost demand.  With rising demand will come additional private investment to supplement existing federal and state solar incentives.

  Is it realistic to expect the U.S. to step up to be a competitive force in the global solar market?

  Tags:    [edit]

  

  Look for even lower solar panel prices in 2011

  Just when you thought the news about solar power couldn’t get any brighter!  Prices for solar panels have fallen by more than 1/2 over the past few years, and now experts believe that the costs will be even lower this year.  In order to compete with companies in China and Taiwan, U.S. solar manufacturers have slashed prices.

  With bargain basement costs and generous government rebates and incentives, more and more consumers are going solar these days.  As a result, solar cell production is ramping up across the United States to meet solar energy demand, expected to double in 2011.

  All this news should be very welcome by homeowners and small businesses.  After all, solar panels used to be out of price range, but are now available for realistic budgets.

  Just how cheap will solar panels get?  Currently, wholesale solar panel prices are at about $1.50 per watt.  Experts believe that the costs will fall another 20% by the end of the calendar year.

  With as much as 30% of the cost available as a solar tax credit, its time to maximize savings  – both on solar panels and monthly electricity bills!  Its amazing to consider the fact that solar energy installations doubled in 2010 (its now at about 1,000 megawatts).  In the next twelve months, solar energy demand is expected to double again, to 2,000 megawatts in 2011.

  Peel and Stick Solar Panels Use Thin Film Solar Technology

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  

  Peel and stick solar panels have a broad range of applications

  Looking for the next big thing in solar energy?  Peel and stick solar panels use thin film solar technology that allows a broad range of applications, as well as cost significantly less than traditional silicon PV solar panels.

  The cost savings come in large part due to the fact that the solar cells do not need glass-covered panels or mounting frames.  Not only does that save money, but it also gives peel and stick solar panels a sleek, less noticeable appearance.  Stick on solar panels are making their way into building integrated photovoltaics like solar power shingles.  Made to look like traditional roof shingles, the thin film PV cells generate clean solar electricity for your home without having to penetrate your roof for brackets and frames.

  Among several companies manufacturing peel and stick solar panels is Global Solar Energy Inc.  Their product is called the PowerFLEX BIPV, which are being ordered in large quantities around the world, particularly in countries in Europe and Asia, that often have building codes that require lightweight PV panels.  Demand for thin film solar technology is expected to explode in the next few years, growing from $1.9 billion in 2010 to more than $16 billion in 2017.

  Peel and stick solar panels can be applied to structures, like homes, and can also be implemented in portable solar power charging systems for military operations and Third World Countries.

  I can imagine a wide range of possibilities for thin film solar cells – the future of solar power is on its way!

  IKEA continues sustainability efforts installing solar panels at its new Denver store

  The über cool Scandinavian furniture store, IKEA, announced this week that it will install solar panels on its new Denver, Colorado store.  The retail outlet is under construction currently, with a projected grand opening in Fall 2011.

  REC solar, one of the leading solar electric system providers in the U.S. is slated to design and install the rooftop solar array for IKEA next month.  Over 2,200 solar panels will cover approximately 60,000 square feet of the store’s roof, and will consist of a 498 kilowatt (kW) system.  The amount of solar electricity generated by the rooftop PV panels is the equivalent of removing 586 tons of CO2 from the atmosphere each year (emissions of 102 cars or powering 64 average homes).

  Solar energy is already being generated at the following IKEA stores in the U.S.: Brooklyn, NY, Pittsburgh, PA and Tempe, AZ.  In addition, solar panel arrays will be installed this year at 8 additional California stores, plus 2 on the East Coast.  IKEA Canada is adding solar systems on three of its Toronto locations too.

  Its all part of the company’s sustainability commitment, described in part here:

  Doug Greenholz, IKEA’s U.S. real estate manager, stated:

  “We are excited about furthering our sustainability commitment with solar panels on the future Centennial store.  Similar to geothermal, solar energy will reduce greatly the new store’s energy costs and carbon footprint as well as contribute to our vision of creating a better everyday life for the many.”

  The new Denver-area IKEA store will be located west of Interstate 25, north of Park Meadows, Colorado.  The construction site covers 13.5 acres and will be home to the new 415,000 square foot retail store.

  

  Rooftop solar panels on an IKEA store

  Worldwide, there are more than 300 IKEA furniture stores in 38 countries.  Founded in Sweden in 1943, the company is the world’s leading home furnishings outlet, offering quality items at low prices.  The installation of solar panels at many of its U.S. locations is consistent with the company’s sustainable efforts.  In fact, TIME has listed IKEA as one of the top eight most global eco-conscious companies.

  Solar Power to Help Troops in Afghanistan

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  Much like solar power can help people that live in developing countries that are miles away from the grid, solar panels are also vital to the success in the field of U.S. troops in Afghanistan.  In fact, a recent report discusses how solar is literally saving lives in military operations.

  

  U.S. Military uses solar power to help in the field

  Using solar power helps troops minimize use of diesel and the need to send out deployments for more fuel. The more times the troops need to refuel, the more exposure they get in the battlefield, which leads to injuries and casualties.  Shockingly, 1 out of every 24 fuel conveys is attacked!

  So why not rely on abundant and free solar power that can be drawn on right from the troops’ positions?

  Not only is solar power safer, but its much more affordable for taxpayers.  When a Marine company started using solar panels to run generators instead of fossil fuels, they saved massive amounts of money as their fuel usage plummeted 90%

  Did you know that air conditioning expenses for U.S. troops in Afghanistan costs $66 million per day?  With solar panels to help run the generators, fuel requirements would drop to 2.5 gallons from 20 gallons a day.  Plus, solar operates silently, which provides a tactical advantage to those positioned in camp.

  Yes, solar power can help troops in Afghanistan in more ways than one!  Read more here.

  Solar Panels at the Cincinnati Zoo

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  

  Solar panels will be the latest attraction at the Cincinnati Zoo

  A new attraction is coming to the Cincinnati Zoo in April 2011.  No, its not a unique endangered species, nor is it a fun new playground for the kids.  Solar panels at the Cincinnati Zoo are being installed right now, which will generate enough clean solar electricity to meet about 1/5th of the park’s energy demands.

  The installation will be the largest urban solar array accessible to the public in the United States.  Which, in my mind, is just perfect for a zoo!  After all, people come to learn about animals and the environment.  What better place to showcase the power of the sun to help us reduce our carbon footprint and reliance on fossil fuels than in an animal kingdom? When the new solar array is operational, visitors will be able to use an interactive kiosk to learn how the solar panels work and how much energy is being produced.

  The solar panels at the Cincinnati Zoo are being designed, installed and operated by Melink Corporation pursuant to a solar power purchase agreement.  The 1.56 megawatt system will include 6,400 solar panels and is projected to cost $11 million.

  New Solar LED Street Light

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  

  LED Solar Street lights similar to these will light up Latin America and Mexico

  A new solar LED street light that can light up the infrastructure of developing regions like the Caribbean, Mexico and Latin America is being developed by Carmanah Technologies.  The EG300-series LED streetlight is part of a new generation of solar LED lights that will meet roadway performance features for global sun-belt regions.

  The new solar LED street light will provide bright illumination at a price that is not prohibitive for developing countries.  In fact, because solar lighting operates off the grid, it does not require expensive trenching or wiring and is more affordable than hard-wired lighting systems.  Perhaps more importantly, the LED street lights will be able to reach stretches of roadways to which the electrical grid does not reach, or where the grid is unreliable, improving safety for drivers and pedestrians.

  The EG300 solar streetlight can deliver the light output equivalent to a 200-watt metal halide light (used for standard streetlight settings). The EG300-series comes in two product sizes.  The LED fixtures are available in standard IES distribution types, are dark-sky friendly, and feature excellent uniformity, according to product information.  They can be used for roadways and parking areas.  The EG300-series can withstand extreme environmental conditions, including hurricane-level winds, tropical heat and humidity, and heavy precipitation.

  Solar Panels More Affordable With New Technology?

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  

  MIT researchers are looking into new solar panel technology

  Over the past 3 years, the price of solar panels has dropped dramatically – in some cases by 2/3 of the original cost.  Yet, with use of new technology, could solar panels be even more affordable?

  Researchers are studying the potential replacement of expensive silicon used in PV panels with a new, less expensive form of carbon in organic solar photovoltaic (OPV) cells.  The Massachusetts Institute of Technology (MIT) is experimenting with use of graphene, which is also known as graphite, in solar cells.

  The mineral – more commonly used as lead in pencils – can form one-atom-thick sheets of honeycomb crystal lattice material with excellent conductive properties.  Graphene could be ideal for creating affordable solar panels for the following reasons: (1) its 100 times stronger than steel; (2) performs better than any other material as a heat conductor; (3) its thin nature makes it extremely flexible and transparent, which is ideal for thin film solar applications including building integrated photovoltaic applications such as solar roof shingles.

  The biggest drawback of using graphene in solar cells is that, since the material repels moisture, it does not adhere well to other components of solar panels.  MIT researchers developed a way to introduce impurities to the graphene to encourage better bonding which, as a result, improved its electrical conductivity.

  Add this new research into the column of “wins” for MIT in the area of solar technology.  Last year, news of its paper solar cells caused quite a stir.  Over time, we’ll see more affordable, and more efficient solar panels with the work of researchers like those at MIT.

  New Solar Cell Manufacturing Plant to be Sited in Oregon

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  

  SoloPower will be manufacturing thin film solar cells in Wilsonville, Oregon

  The state of Oregon, on the West Coast of the United States, will soon be the home of another new solar cell manufacturing plant.  Last week, SoloPower announced that it will manufacture its flexible thin film solar cells at a new facility in Wilsonville, just 20 minutes south of Portland.  Certainly this news will add to Oregon’s leadership in the field of solar energy!

  A number of green solar jobs will be created as a result of SoloPower’s plant in Oregon.  Initially, 170 new employment positions will be created during the construction of a 75 megawatt (MW) manufacturing line.  Eventually, the plant will have a 300 MW capacity and employ about 500 workers.

  Oregon Governor John Kitzhaber, commented about the new solar cell manufacturing plant and associated green jobs:

  “SoloPower is bringing exactly the kind of new jobs Oregon needs. By bringing their manufacturing headquarters to Wilsonville, we are continuing on the path toward establishing a stronger clean technology manufacturing base in Oregon.”

  SolarPower is a California-based company.  So why is it building a state-of-the-art production facility for its solar modules in Oregon?

  Two words: tax incentives.  The Small Scale Energy Loan Program (SELP) Advisory Committee recommended approval to the Oregon Department of Energy for a $20 million loan to SoloPower.  In addition, SoloPower is seeking a Business Energy Tax Credit (BETC) of $20 million from the State of Oregon.  SoloPower CEO Tim Harris commented:

  “Over the past year, SoloPower has considered several alternative sites. Oregon is an exceptional location for our long-term growth.  SoloPower greatly appreciates the partnerships it has formed with the State of Oregon, the Oregon Department of Energy, Clackamas County and the City of Wilsonville.  Oregon’s business friendly environment, excellent support programs, and highly skilled work force made locating our new manufacturing facility in Oregon an easy decision.”

  The benefits of the Wilsonville location go both ways.  SoloPower will enjoy tax advantages and government incentives, and Oregon boosts its national reputation as the home of the top solar manufacturing cluster, while locals enjoy the creation of green jobs in Oregon.

  Solar Power Should Play into Cost of Powering Electric Cars

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  

  Solar panels cover this parking garage, allowing for clean charging of EVs

  Following a very successful North American International Auto Show (NAIAS) in Detroit this month, consumers and the media are thrilled about the new electric cars that are hitting the market, or due to be released soon.  In fact, EVs took two of three spots for the “North American Car and Truck of the Year,” with the Chevy Volt and the Nissan Leaf battling for the top prize.

  Today, there are 100% electric cars, which do not use any gasoline and have a range of about 100 miles on a single charge, and plug-in electric hybrids, which offer a gasoline “back-up,” if you will when your electric charge is depleted.  For both types of models, questions arise regarding how to charge them and the price of transportation.

  Solar power should play into the cost of powering electric cars – but it is not yet a factor in official estimations.  Most owners of EVs will plug into a 240 volt in their garage to charge the batteries.  Fast-charging stations, like the ones announced in Washington State, will also be sprouting up along major thoroughfares.  Critics note that these options rely on grid-based electricity which is primarily generated from fossil fuels.  So, while there are no tailpipe emissions, we’re still using a source of energy that is not ideal.

  That’s where solar energy comes into play.  PV panels placed on a garage or carport can allow you to use solar to charge your vehicle at an even lower cost than “regular” electricity.  Solar powered public parking garages and park and ride facilities also will continue to be developed – particularly in regions like the state of California.

  The Environmental Protection Agency (EPA) has had some difficulty in preparing estimated costs of powering electric cars versus a traditional gasoline-powered car.  Several publications have tried to help consumers compare and contrast the costs, but most fail to include renewable energy-based electricity like solar power in the mix.

  In an Edmunds.com article, The True Cost of Powering an Electric Car, Features Editor Carroll Lachnit notes that the cost of recharging an electric car depends on local utility rates, which can vary based on time of the day and location of the power plant.  Similarly, in “Decoding the Electric Car MPG” Paul Seredynski, Senior Editor at Edmunds’ AutoObserver.com notes the following:

  “The issue is that this rating [MPGe]  really doesn’t have much to do with fuel economy.  The MPGe rating is only useful for comparing the relative energy consumption of gasoline (or hybrid) cars with that of electric cars.”

  In addition, the national average for electricity costs is used for the rating which not only doesn’t figure in local variations in price, but does not take into consideration solar electricity or other renewable-based power.

  

  Solar panels on your garage can minimize your EV charging costs

  Estimating the cost of charging an EV using solar power will complicate the calculations but should be noted as an alternative.  If solar panels installed on your home or garage offset 100% of your electricity costs, your cost of recharging an electric car is – essentially – zero (costs are upfront with a solar panel system purchased outright, or monthly with a solar lease or power purchase agreement).  Defraying even a portion of your energy needs with PV solar panels will, of course, reduce your cost per watt.

  If you are thinking about purchasing an electric car, be a smart consumer and consider that the information from the auto manufacturers and EPA is not 100% accurate, nor complete!  Add solar power charging to the mix and you’ve just cut your transportation costs even further.

  Stewart Brand Asks: Is Solar Power the Future?

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  

  Stewart Brand speaks at Ford's Driving Green Technologies presentation at NAIAS

  I have just returned from a great 2-day event in Detroit, hosted by Ford Motor Company* at the North American International Auto Show in Detroit, Michigan.  Ford invited over 100 bloggers from 10 countries to cover its Driving Green Technologies and learn about how the auto manufacturer is not only building new, eco-friendly cars, but also addressing the environmental impacts of its own operations.

  On Monday, we heard a terrific presentation by Stewart Brand on sustainability.  Mr. Brand discussed energy in general, raising the question  – at least in my mind – is solar power the future?

  If you ask Mr. Brand, the author of the Whole Earth Catalog and a well-known publisher on “green” topics, he would answer the question with an unwavering, no.  Considered to be a founding father of the eco-movement, starting in the 1960s, Brand has recently changed his position on nuclear energy and even clean coal, arguing that these two technologies make more sense for the world than wind or solar.

  Brand also discussed some of these views in a TEDtalks video from 2009:

  

  Ford's Driving Green Technologies event included a discussion with Stewart Brand

  At Ford’s Driving Green Technologies event, Stewart Brand presented a slide show and compelling talk about renewable energy and the realities associated with development of large, utility-scale sized power plants.

  Consider this information:

  World-wide, baseload electricity is generated by the following power sources: coal/natural gas/oil (68%), hydroelectric (16%), nuclear (15%), wind (0.5%) and solar (0.1%).

  On a utility scale, both wind and solar require huge amounts of land and create environmental impacts.  For example, to generate 1 gigawatt (GW) of wind power, you need 250 square miles of land.  For solar, 1 GW of energy requires 50 square miles of bulldozed area.

  With this backdrop, Brand noted that there is a significant difference between energy farms and energy factories.  Renewables like solar and wind take up too much land and there is rarely a good place to site them.  On the other hand energy factories (coal, gas, nuclear) have less impact from a land resource standpoint.

  Brand’s position is that nuclear has the smallest waste stream and makes the most sense as far as “renewable” energy resources go.  Clean coal should also be mandated in part to raise the price of the resource which is still both abundant and ridiculously cheap (either that or “tax the hell out of it,” he commented).

  Heck, we can even take nuclear weapons and transform them into energy generating resources:

  Personally, I found Stewart Brand’s talk on sustainability informative, yet perhaps a bit closed minded with respect to the future prospects of solar power and wind.  In particular, Brand didn’t address solar from a distributed generation standpoint.  Putting solar panels on rooftops to defray energy costs at the very site at which they are located saves time and money for the consumer of the renewable resource.  Solar energy from a solar power plant not only requires land resources and impacts the environment, but there is the expense of getting the electricity from the solar farm to the power lines that will deliver it to the end user.

  I’m for the idea of continuing to explore a number of renewable energy options – and not writing off solar, wind, biomass, or tidal.  In my opinion, putting all our energy “eggs” in a nuclear basket could leave us fried.

  What do you think about the question, is solar power the future?  We’d love to read your comments!

  2011 Nissan LEAF Electric Car Has Solar Panel Option

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  

  The 2011 Nissan LEAF

  I’ve been spending the past couple of days in Detroit at the North American International Auto Show.   Let me just say that there are a ton of green cars that are on the market already, coming to consumers soon, or concepts that may develop to additional options.  Among several new electric cars that have been introduced is the new 2011 Nissan LEAF.

  We chatted with several of the Nissan representatives about the LEAF, which is now available in several U.S. markets.  Not only can this 100% electric car get up to 100 miles on a single charge, but there is a solar panel option to help operate the HVAC system within the vehicle without draining the battery.  The PV panel is mounted on the spoiler of the car and is sleek and low profile.  We were told that of the people that have bought, or pre-ordered the Nissan LEAF, more than 70% of them are choosing the solar panel option!

  

  Introducing the 2011 Nissan LEAF

  In case you are wondering, the MSRP for the Nissan LEAF in the U.S. is approximately $32,000.

  With a $7,500 rebate from the federal government, you’ll end up paying about $25,000 for the 5-passenger car that runs on zero fuel and has zero carbon emissions.  The solar panel option is about $1000 over MSRP.

  Excitement is high for green cars like the Nissan LEAF.  Even with a down economy, consumers are flocking to electric vehicles and other green cars.  Perhaps the most serious competitor of the Chevy Volt, Nissan LEAF has a long waiting list of customers who cannot wait to get behind the wheel of this revolutionary EV.

  Other information of note include:

  • Charging outlet in the front of the vehicle
  • Charging time approximately 6-8 hours with a 240 volt outlet for a full charge
  • Quick charging of 30 minutes can be accomplished
  • Range of 100 miles without recharging
  • Seats 5 passengers
  • Battery mounted underneath the vehicle instead of taking up trunk space
  • Upholstery created from recycled plastic water bottles

  I’d love to drive a new 2011 Nissan LEAF.  Check back with its website, or follow @NissanLEAF on Twitter for more information about when this electric car will be coming to a city near you!

  Solar Power at Kaiser Permanente’s Santa Clara Medical Center

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  

  Kaiser Permanente solar power at its Santa Clara facility

  One of the first major hospitals in the United States to rely on a significant amount of solar power for its energy needs is Kaiser Permanente’s Santa Clara Medical Center in California.

  The center is the first of 15 California-based Kaiser Permanente facilities to have solar panels installed on its roof.  By the end of 2011, Recurrent Energy will have installed solar power systems at the rest of the properties.  These systems will generate 15 megawatts (MW) of solar power, which will cover 10% of the energy requirements of the properties and will represent one of the largest sustainable energy programs in the health care industry in the United States.

  According to Gregory A. Adams, group president, regional president of Kaiser Foundation Health Plan/Hospitals, Inc. in Northern California:

  “Kaiser Permanente has a long history of energy conservation and environmental stewardship, and our use of solar and other forms of renewable energy further demonstrates our ongoing commitment to improving the overall health and well-being of our members and the communities we serve.”

  Solar power will be provided to Kaiser Permanente through a power purchase agreement with Recurrent Energy, which will own and operate all of the solar panels and systems.  The panels themselves will be installed on Kaiser Permanente hospitals, medical offices and other buildings.  The agreement allows Kaiser Permanente to retain the Renewable Energy Credits for the solar projects, and to reap the benefits of lower costing, cleaner solar power.  The move will save the company money, as well as reduce its carbon footprint.

  

  Solar Panels at the Kaiser Permanente Santa Clara parking garage

  The new solar power array at Kaiser Permanente’s Santa Clara Medical Center is the latest in its efforts to green its operations.  Since it opened its Modesto, California facility in 2008, which also has solar panels on its roof, the company has operated some of the country’s “greenest” hospitals in Modesto, California.

  San Francisco's Solar Map

  Do you live in an area that gets lots of sunshine?  Ever wonder about your city’s solar power potential?   You can get precise data regarding the projected kilowatt-hours of solar electricity that could be generated by solar panels on your home or business, if a solar map has been prepared for your region.

  For property owners in Colorado, check out the new Denver Regional Solar Map and type in your address.  The website will then give you a bird’s-eye view of the location with specific information for the property, including the roof size and solar potential of the home or business.  You also get information regarding potential shading and the angle of your roof.

  The site will even tell you about potential solar incentives and rebates available in your area, as well as:

  • Kilowatt generation by month
  • An installation estimate
  • Information on estimated yearly electrical bill savings
  • A form you can complete to request more information from solar installers.

  Denver is just the latest city to have developed solar maps to show solar power potential.   Since 2007, New York City, San Francisco, Boston, Salt Lake City, Los Angeles and Portland, Oregon have also put together comprehensive maps that showcase the best areas to install solar panels, potential energy savings and cost of PV solar power systems.

  Many of the solar maps are partially financed by the U.S. Department of Energy’s Solar America Cities program, and are intended to simplify consumers’ ability to research solar energy options.  One thing is for certain – since the maps went live in many of these cities, solar panel installations have more than quadrupled over the past few years.

  Don’t have a solar map in your city yet?  Write to your councilmembers and ask them to work with the USDOE in preparing one for your region!  Not only will it help green your city, but it boost green jobs, as well!

  Solar Panel Leasing Comes to Oregon

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  

  Solar panel leasing comes to Oregon

  For homeowners wanting to switch to solar power, one of the biggest concerns is the upfront cost.

  With a solar panel lease, you can have solar panels installed and start enjoying much cheaper electricity (and with minimal carbon emissions) with practically no money down.  This is because ownership of the solar panels stays with the manufacturer, and you only pay a small monthly fee – less than your current power bill.

  Leasing solar panels is a new idea that is just starting to get traction across the U.S. and Canada.  This week, we learned that solar panel leasing is now available here in my home state of Oregon via programs offered by SolarCity®.   Residential solar leases can be obtained for as little as $20 a month!  This means that you can start saving right away, instead of trying to calculate a return on investment period as you would when you buy solar panels.

  Solar panel leasing is now available in Oregon because the Oregon Department of Energy adopted new rules effective January 1 that allow customers that lease solar panels to receive the residential tax credit (RETC) that was previously only available to customers that purchased solar systems. What this means is that the system cost that is not covered by lease payments can be deferred until the homeowner receives the tax credit, eliminating any upfront costs associated with switching to solar power.

  For more information how a SolarCity solar panel lease works, watch this video:

  There are many financing options available to Oregon customers who wish to lease or purchase solar panels from SolarCity.   You can choose between a prepaid lease, partially prepaid lease with lower monthly payments and even cash purchase.  During the entire 15-year duration of the lease, SolarCity will monitor, repair, insure and guarantee the performance of the solar panels installed on your home.  According to Rob LaVigne, SolarCity’s regional director in Oregon:

  “For less money each month than the cost of two movie tickets, Oregon homeowners can install solar power.  Our Oregon lease option should make solar accessible to a wide range of homeowners across the state.”

  If you live in Oregon and are a customer of Portland General Electric or Pacific Power, you are eligible for the solar panel lease program through SolarCity.  Contact the company directly at 1-888-SOL-CITY (1-888-765-2489) for a free consultation, or visit SolarCity’s webtsite: www.solarcity.com/request.

  Residential Solar is Cheaper Thanks to These Three Innovations

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  

  Thin film solar is less expensive and more attractive than regular PV panels

  I’m here to tell you that 2011 is the year to install solar panels on your home.  Not only did Congress recently vote to extend the solar tax credits another 12 months, but residential solar is cheaper than ever, thanks to these three innovations.

  1. Thin Film Solar
  

  Think of home solar panels and what probably comes to mind are the bulky PV panels that look like skylights and require expensive brackets and roof penetrations to install.  These days, thin film solar is allowing for streamlined solar roof shingles that blend right in with your roofing.  Also called Building Integrated Photovoltaics, the benefit of using thin film solar panels on your roof go beyond their sleek profile.  Thin film cells are much less expensive (compare at $1 per watt vs. $2 per watt for traditional crystalline PV panels).  If you are looking for cheap solar power, thin film is the way to go!

  2. Microinverters

  Inverters – which take the direct current absorbed by solar panels and convert it into alternating current to be used when we plug in our appliances and gadgets – have traditionally been an expensive component of a residential solar power system.  Starting at $3,000 and increasing in price from there, inverters may comprise up to 1/3 of the cost of going solar.

  Now, however, you can go with microinverters to save money and give you flexibility with your home solar power.  Microinverters are installed on each PV panel, and cost only about $200 a piece.  If you have only 3-4 solar panels on your roof, you’ll spend well less than $1000 for inverters.  In addition to the lower cost, microinverters boost the efficiency of your solar panels.  And, they make it easier and less time consuming to install solar.

  

  Testing microinverters on solar panels

  3. Solar Panel Racking Solutions

  The racks that hold solar panels on your roof comprise at least 1/4 of the cost of a solar panel system, and are quite expensive to install – not to mention time consuming and dangerous.  But companies like Zep Solar are now selling solar panel racking solutions that eliminate rails, and include grounding systems that can be installed in no time.

  Is 2011 your year to go solar?  Why not!

  The cost of solar energy is about 1/2 of what it was 5 years ago.  With added incentives and tax breaks, demand is rising which further drives solar technology innovations.

  Have a Happy Solar New Year!

  How to Go Solar Without the Headaches

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  

  Install solar panels without the headaches

  You want to install solar panels on your home or business, but where do you start?  In addition to the growth in the number of solar manufacturers, new businesses are springing up to help you go solar without the headaches.

  When considering renewable energy options like solar panels, factors including the number of kilowatts, price, design, rebates, incentives and tax credits all come into play.  And – when we’re talking credits and incentives, there is an array of options from the federal, state and even local governments.

  Do you know how many solar panels you’ll need?  How much will they cost?  Where should they be placed?  Do you need a permit?  How do you get a tax credit or rebate?

  If you could have someone help you get through all the options and considerations that may be acting as a hurdle to going solar, would you do so?

  A recent New York Times article examined how to go solar without the headaches with the help of a company called One Block Off the Grid.  In fact, we’ve blogged about 1BOG before.

  Brad Burton, 1BOG’s vice president of product and strategy explained:

  The way that solar is sold in the U.S. today is lengthy, complicated, and often a stressful process for an individual homeowner to go through.  There aren’t very many sources of information you can turn to with accurate, reliable info.”

  One Block Off the Grid helps negotiate group discounts on solar panels, as well as navigating the array of regulations and red tape.  With the help of 1BOG, homeowners in California can expect to recoup the investment of a solar panel system in a mere 6-9 years.  No – I didn’t type 69 years.  Its well less than 10 years to break even when you install solar panels in the Golden State!

  Yet 1BOG can help you in many states across the country.  It has operations in 17 states (as of the date of this publication).  And it probably could have helped Tania Reuben, of Los Angeles, a green blogger who operates PureNaturalDiva.com.  She has been spending numerous hours crunching numbers to determine whether and how to pay for a 17-kilowatt solar panel array on her home that will generate clean electricity to power 80% of her needs.  According to the New York Times article, she has spent hours since Spring 2010 to pencil it out, making calls to her bank, the solar panel installer and her accountant.

  She remarked:

  “If this is how hard I’m feeling it is, and I have that extra reason to be committed, it makes me really concerned that the average consumer is going to run into a couple of roadblocks and then go, ‘You know what? This is too complicated.’”

  Bottom line – if you want to go solar without the headaches, call in the professionals.  Not only can organizations like 1BOG help you save time and frustration, they may even be able to negotiate a discount on the solar panels’ price.

  The Zephyr Solar Powered Plane

  2010 has been a great year for solar power!  Among technological advancements, lower prices for solar panels and continued governmental incentives, this week news broke regarding an official record for a solar powered plane flight.  Sure, there have been other solar powered plane flights this year (the Solar Impulse among the most notable).

  The Zephyr is an unmanned air vehicle (UAV), fitted with solar panels, that took off this summer for a non-stop, 2 week flight over the United States.  Taking off on July 9, 2010 from Yuma, Arizona, the plane flew nearly 14 days without stopping to refuel, landing on July 23.  The plane was built in the U.K. and the record-breaking flight was confirmed by the Federation Aeronautique Internationale (FAI).

  Wondering what potential uses there are for a solar powered plane?  While these type of aircraft may not be in the near future for passenger flights, the Zephyr could be helpful in the near future for military, as well as search and rescue operations.  Because it can fly both day and night without having to refuel (and without the added weight of carrying fuel), it can help advance long term strategy more efficiently.

  Silicon PV panels on the plane’s wings are thin and lightweight.  Solar energy absorbed from sunlight during the day recharge lithium-sulfur batteries for operations overnight.  Its no wonder that the Zephyr solar powered plane has bee nicknamed the “Eternal” plane, since it can stay aloft when other types of aircrafts must return to refuel.

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  

  Chevy's going to help the country go green!

  Automobile manufacturer, Chevrolet, has been garnering positive headlines for itself recently!  In addition to the release of the 2011 Chevy Volt (a plug-in electric hybrid car), it recently announced it will invest $40 million for advancement of clean energy over the next several years.

  More specifically, Chevrolet’s goal is to offset 8 million metric tons of CO2 emissions, which would be the emissions from the nearly 2 million cars it expects to sell in 2011.  It is also equivalent to the electricity used by 1 million average American homes.

  General Motors CEO, Dan Akerson commented:

  “Chevrolet’s investment is an extension of the environmental initiatives we’ve been undertaking for years because the solution to global environmental challenges goes beyond just vehicles.”

  Chevrolet’s investment of $40 million will go to support nationwide projects that promote renewable energy, responsible consumption of natural resources and energy saving technologies, as well as investments in third-party organizations.

  In December 2010, the automaker started selling the Chevy Volt in California, Texas, New York, and Washington D.C.

  Where does it pay to go solar in the U.S.?

  Ever wonder about the top three states in the U.S. with solar potential?  If you guessed California, Florida and Arizona, you are only 1 for 3!

  Arizona State University’s School of Business recently named Arizona, Colorado and Georgia as the top three states with solar potential.  In other words, people who live in these states would benefit most from converting to solar power.

  The findings of the report were determined based on the current cost of grid-based electricity, the amount of sunlight each state receives on an annual basis, and state-by-state solar initiatives.  Where power costs more, residents may be more inclined to switch to renewable energy resources like solar energy.

  The study, published in The Electricity Journal, ranked states in the U.S. with respect to generation and consumption of solar energy.

  “We see a growing trend by states to increase the importance of renewable electricity generation,” says assistant research professor Matthew Croucher, who authored the report. “However, the biggest take-away from this study is that if the U.S. is serious about maximizing the societal benefits of solar generation, then we need to look at the national level at how different states can serve not only their own needs, but also those of other states with less ability to create electricity using solar technologies.”

  And its not only homeowners that can benefit from installing solar panels.  Commercial enterprises, government entities and institutions should also consider going solar if they have properties in the top three states with solar potential.

  The full study, including the rankings of all 50 states, can be found at [www.sciencedirect.com] . It is called the “Optimal Deployment of Solar Index.”

  Concentrated Solar Power System to be Building Integrated?

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  

  Concentrated Solar Power becomes Building Integrated

  Concentrated solar power is a technology for generating utility scale solar power.  But Syracuse’s Center of Excellence in Environmental and Energy Systems (SyracuseCoE) is showing that it can also be building integrated and used on a smaller, direct generation scale.

  At SyracuseCo, the building itself is a LEED-platinum-certified, 55,000 square-foot building that serves as a testing ground for renewable energy and efficiency technologies.  But head to the south wall of the building and there, you will find a concentrated solar facade (pictured above), that serves multiple functions.

  This is building integrated photovoltaics in a whole new light!  The 8×8 foot facade includes clear pyramid heliotropic lenses that concentrate sunlight on high-efficiency PV solar cells.  Solar energy is generated at an efficient rate, and any additional power not needed for electricity is used to heat the building and water.  Not only that, but the clear panels add natural light for the interior, which reduces lighting requirements.

  The facade was designed by the Center for Architecture Science and Ecology and HeliOptix has marketing rights.

  New York Jets Solar Powered Facility

  In 2010, several NFL teams decided to go solar.  The New York Jets has the largest PV (photovoltaic) panel system of any of the teams.  Recently, 3000 solar panels were installed at the team’s training facility.  The panels will generate 750,000 kilowatt hours (kWh) of solar electricity, offsetting about 540 tons of CO2 emissions.

  According to Thad Sheely, New York Jets executive VP of finance and stadium development:

  “This project is the first of many green initiatives on behalf of the team, and we are proud to be green in color and also in deed.”

  The panels installed on the rooftop of the NY Jets facility will save the company thousands of dollars each year in utility bills.  Perhaps more importantly is the potential influence of a professional sports team in showing the rest of the country the benefits of solar energy.  It goes without saying that many people emulate sports teams and players.  The installation of solar panels on an NFL team training facility might encourage others to consider the renewable energy resource.

  Two other NFL teams have turned to solar power for their facilities. The New England Patriots have a 525-kilowatt solar array at Foxborough Massachusetts’s Patriot Place, and the Seattle Seahawks have an installation at Qwest Field.

  Tags:    [edit]

  

  The Sunfish allows for plug-in solar power

  I’ve talked with many homeowners who want to install solar panels, but are worried about the cost.  But now you can go solar at a fraction of the cost hassle normally required to do so.

  A new home solar kit is literally plug-in solar power.  Called the “Sunfish,” all that is required is an electrical outlet and a large, southern facing window that gets regular exposure.

  The Sunfish generates 1,000 watts of power, which can completely offset the energy requirements of a large appliance, such as your refrigerator.  Or, you can get a smaller version that generates 200 watts of solar electricity – enough to power your lights, or maybe your laptop!

  Plug-in solar power will be available in 2011, when the Sunfish goes on sale.  The 1,000 watt version will cost about $3,000-4,000.  Unlike home solar panels, the cost of the Sunfish can be recouped in a mere 4 years.  After that, you’ll save several hundred dollars a year in electricity costs.

  The Sunfish is a Clarion Technologies product.  It weighs 200 pounds and takes 6-8 hours to fully install.

  Thousands of new solar jobs coming in 2011

  In the market for a career in the renewable energy industry?  The Solar Foundation reports that thousands of solar jobs will be created in 2011.  Based on a census of American workers, an estimated 24,000 new solar jobs will be available in the coming year.

  In fact, the number of solar workers keeps increasing.  As of August 2010, there were about 100,000 jobs in the solar industry in the U.S.  That is double the number of green jobs from the prior year!

  At least there is one sector of the economy that is showing strong growth.

  Most of the solar firms surveyed by the Solar Foundation indicated they would be adding to their workforce next year.  A mere 2% said they would lay off solar workers.

  So, what types of solar jobs will be created?

  • Solar installation, including PV installers, solar electricians and roofers with solar experience
  • Manufacturing
  • Salespersons
  • Wholesale, trade and other solar industry functions, including energy auditors, solar designers, engineers and technicians

  The best states in which to secure a solar job include California, Arizona, Colorado, Pennsylvania, Texas, and Michigan.  Do a quick Internet search for solar firms in your region and then check employment opportunities.

  You could also try a jobs fair – renewable energy companies are regularly hosting events at which you can review green job opportunities.

  Three Reasons You Should Go Solar Today

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  

  Why not install solar panels soon?

  Have you been wondering about whether you should install solar panels on your home?  Still undecided?

  Here are three reasons you should go solar today:

  1. Solar Panels may be as cheap as they are going to get. Over the past 2 years, prices on solar panels and other solar products fell dramatically – by 50% or more.  At the same time, government incentives for property owners installing solar panels make it much more affordable to do so.  If you are waiting for the “bottom” as far as solar panel prices, experts say we are there.  If you wait, they may even become more expensive as the result of changes in demand, silicon production, and global market/subsidization shifts.

  2.  Solar incentives and rebates are the most generous for early investors.  Its the classic, “get the deal while its hot” approach.  States and local governments reward those who take advantage of solar rebates more generously to build a sense of urgency.  You don’t want the incentives to expire while you try to make up your mind to go solar, right?  In fact, in Pennsylvania, the state has set lofty goals for residential solar panel installation.  To meet the mandated numbers, those who help get the ball rolling will be rewarded with generous solar incentives.  Wait, and you’ll get less.

  3. You can start saving on your electricity bill immediately. If you are like most Americans, you spend over $1200 a year on grid-based electricity.  And, power companies do not hesitate to raise rates each year, passing on infrastructure improvements to customers at a rate of 6% annually.  Did you know that, for every $1 you save in electricity costs each year, your home increases in value by over $20?   You have the potential of up to $24,000 in “instant equity” simply by installing solar panels.  Also, with net metering, you can turn your meter backwards and get credit for extra energy generated by a home solar panel system.

  Immediate electricity savings, no more uncertainty about future rate increases, and the satisfaction of making an investment that will more than pay for itself.  More great reasons you should go solar today!

  Lincoln Financial Field is Going Green

  Happy Thanksgiving – its time for turkey and football!

  And, if you want a little extra greens, then consider this:  the home field of the Philadelphia Eagles – Lincoln Financial Field – will be 100% energy independent next year.

  Solar and wind will power the home of the Philadelphia Eagles with the help of SolarBlue by September 2011.  A number of 20-foot vertical axis wind turbines will be installed on the roof, as well as 2,500 solar panels on the facade of the stadium.  The stadium will also have a 7.6-megawatt onsite dual-fuel cogeneration (biodiesel and natural gas) plant.

  The solar and wind system, as well as the power plant will produce enough green energy to power 26,000 homes, off-setting over 480,000 tons of greenhouse gas emissions.  More than 200 green jobs will be created, too.

  The $30 million solar and wind power project will be installed and operated by SolarBlue for the Philadelphia Eagles under the terms of a power purchase agreement over 20 years.  Estimates are that the Eagles will save $60 million on power over the life of the agreement.

  Greening the stadium of the Philadelphia Eagles?  I’ll take seconds.

  Solar Powered Ambulances

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  Solar powered ambulances are a hot way to keep medications cool.  In Austin Texas, two new solar powered ambulances have been added to the fleet.  Now, instead of leaving the engine running (and the A/C cranking) when patients are transferred into a hospital, solar panels on the roof of the vehicles generate power to keep medications at proper temperatures and also maintain other equipment.

  Solar powered ambulances are helping to save fuel and money for the Austin-Travis County Emergency Medical Services.  The EMS is following the lead of North Port Florida which has had solar powered ambulances in its department this year.

  With solar panels on the ambulances, the engines can be turned off during transport times, which can take 1/2 hour or more.  Equipment will still maintain full power, including refrigeration units for medication.  Using free solar power instead of costly fossil fuels burned during engine idling, the department estimates that it will save up to $4000 per year to operate each solar powered ambulance.

  Eventually the EMS plans to add 5 more solar powered ambulances to its fleet, for a total of 7.  Savings of $28,000 per year will add up quickly – not to mention the lower carbon footprint!

  Solar Electric Trike

  One of the greenest ways to get around is on a cycle that’s powered with solar energy.

  Check out the solar electric trike above – created by New York sculptor Josh Hadar.   This is one ride that could make “green the new black.”  Not only is it sleek and eco-friendly, its perfect for commuting around town.

  Consider these fast facts about the solar electric trike:

  • Four 12-volt lead-acid batteries
  • 15 horsepower Mars Electric motor
  • Max speed: 45 mph
  • Charged by six 125-watt solar panels
  • Single charge gives you a 30 mile range, perfect for commuting

  As electric vehicles start hitting mass consumer markets this year, the solar electric trike could be one way for you to get on the EV bandwagon.  Way cooler than the Chevy Volt, in my opinion!

  Hadar’s solar electric trike is built 100% off grid.  Electric tools used in production were charged by Hadar’s studio’s rooftop solar panels.  The carbon steel tubing was shaped by hand.

  Solar Panels power Matava Fiji's Premier Eco-Resort

  I am just home from an amazing week in Fiji!  Tourism Fiji asked me and several other bloggers to travel to the islands to stay in and experience some of the greenest hotels and resorts that the nation has to offer!

  My trip began with 2 nights at Matava Fiji’s Premier Eco-Resort.  The resort is located on Kadavu, which is a 45 minute plane ride from Nadi International Airport – plus a 1-hour boat ride.  Although relatively large in size, Kadavu is wild and somewhat primitive; its a place you can experience the “real Fiji.”

  Matava is 100% off-grid, with electricity primarily coming from solar panels installed on the roof and ground-mounted at the property.  One of its owners, Adrian Weeks, explained to me that, even with periods of clouds and rain, the solar panels usually provide all the power needed for the resort.  After about 4 days of rain (like we had when I arrived), Matava Fiji’s Premier Eco-Resort will need to run a diesel generator for only about 1 hour to fully recharge the system’s batteries.

  

  One of the Solar Panels at Matava Fiji's Premier Eco-Resort

  Solar power is very important to this island in the Republic of Fiji.  Kadavu is largely undeveloped from an infrastructure standpoint.  Although numerous Fijian villages support three high schools, there is not a unified road system across the islands.  Transportation is mostly by foot and by boat.  In fact, to get to Matava Fiji’s Premier Eco-Resort, you need to take a 1-hour fishing boat ride from a location near the airport.

  Most of the islands’ population live in villages that are completely self-sustained.  They grow, harvest and fish their own food, handwash and hang clothing to dry, and generally support each other in raising children and household duties.  Lighting is either by kerosene lamps or solar powered lights.

  And the Fijians are extremely happy!

  

  Matava Fiji's Premier Eco Resort

  At Matava, you can focus more on your vacation and less on the “rest of the world,” if you will.  No wireless and limited cell service means you need to simply un-plug and enjoy the surrounding beauty and activities.

  The solar powered resort has simple, yet clean burés for your enjoyment.  Queen-sized beds in the main room are flanked by 2 side tables, an open closet and a sitting area.  In the bathroom, natural light streams in through ample sky lights.  There are no electrical outlets – so forget about hairdryers or shavers!  In fact, electrical lighting is very limited; you will probably just use kerosene lamps after your community dinner to head back to your room.

  Have a computer, camera or cell phone that needs re-charging?  The main lodge includes electrical outlets fed with solar power from the resort’s solar panels.  Wireless service – not so much!

  But what is a vacation about anyway?

  Solar Hot Water System Pays For Itself

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  

  Solar hot water system is more economical than electrical water heating

  Think that solar power is too expensive, with a return on investment period that stretches out longer than you’ll own your home?  When it comes to solar hot water, its time to think again.  A solar water heating system may pay for itself in a mere two years in energy savings.

  Why use electricity to heat water when you can use direct heat from the sun?

  Researchers Vivek Khambalkar, Sharashchandra Gadge, and Dhiraj S. Karale at the Dr Panjabrao Deshmukh Agricultural University in Maharashtra, India, compared solar hot-water production per liter with electrical energy approaches and found that solar heating is 57 percent of the internal rate of return.  They explained:

  “Solar energy is the only renewable energy source that has wide range of uses with commercial viability. Solar energy provide water heating, air heating and electricity through various modes of applications. The use of solar energy for thermal purposes is the most cost-effective way of utilizing the resource. A solar water heating system satisfies the need of warm water.”

  The researchers confirmed that a solar hot water system pays for itself in just two years, compared with at least 5 times that for a photovoltaic solar panel system.  When you estimate that a solar water heating installation will last about 20 years, your investment will pay for itself about 5 times over!

  Solar Power to Melt Ice and Power Street Infrastructure

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  

  Let's use solar power to melt ice from roadways

  Its an idea that makes perfect sense, when you think about it.  Why not use solar power – radiant heat energy – to melt ice from streets and power street infrastructure – street lights, roadway signs, etc.?

  Researchers at the University of Rhode Island are developing ways to harness solar energy – in particular, the radiant heat that warms pavement during hot summer months – and store it for future, clean energy uses.  They’ve come up with several ideas that could be revolutionary when it comes to solar power.

  First, using the ubiquitous concrete Jersey barriers along highways, photovoltaic cells could be added along the tops to generate energy for street lights and roadway signs.  Building on the idea of solar roadways, PV cells also could be embedded in the pavement.

  

  Solar infrastructure under roadways

  Second, solar energy absorbed by pavement could be used to heat water in pipes installed underneath the asphalt.  Solar heated water could be piped to locations to melt ice on roadways, reducing the need for road salt, which can damage the environment.  Researchers are even exploring the possibility of taking the heated water and using it in a steam-powered turbine to generate electricity.  According to graduate student Andrew Correia:

  “One property of asphalt is that it retains heat really well, so even after the sun goes down the asphalt and the water in the pipes stays warm. My tests showed that during some circumstances, the water even gets hotter than the asphalt.”

  Finally, URI researchers are exploring the potential of using thermoelectric effect to generate electricity. When two types of semiconductors are connected to form a circuit linking a hot and a cold spot, there is a small amount of electricity generated in the circuit.  By embedding thermoelectric materials in the roadway, either at different depths, or in shady and sunny areas, temperature difference could be obtained for electricity generation.  The power could be used to melt ice, or illuminate street lights.

  Just a few of the bright ideas in solar research that can help power our lives with clean, renewable solar energy!

  Tags:    [edit]

  

  Solar attic fans can save you money and your home!

  Have you heard about solar attic fans?  Using free solar energy, these photovoltaic devices can help increase airflow through your attic, without hiking electricity bills.

  Heat rises, which often makes the attic the hottest area of the home.  Add in trapped moisture, and anything you are storing up there will be damaged.

  Over time, structural elements of your house will also suffer, unless you reduce the temperature and control moisture levels in the attic.  An added bonus is that, by cooling the rafters, the living spaces in your home will also take less energy to keep at a comfortable temperature.

  With solar attic fans, you can use the convenient power of the sun to generate the electricity needed to keep the temperature of your attic within 5-15 degrees of your living spaces.  Air flow also prevents moisture build up.

  If you are interested in installing a solar attic fan, you can use federal, state and local renewable energy incentives to allow you up to a 30% federal tax credit, and as much as 80% savings through state and local incentives.

  That’s definitely something to celebrate this time of year!

  Solar Power Project in Central Oregon Receives Permit Approval

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  

  Solar power plants to be built in Christmas Valley, Oregon

  Utility scale solar power plants in Christmas Valley, Oregon have caused both interest and controversy in recent months.  The Central Oregon location has abundant sunshine and little rain.  Plus, its located near power lines which makes siting a solar power plant more convenient than having to transport solar electricity miles to an existing grid line.

  This week, a solar power project in Central Oregon received permit approval, which will make it the largest solar facility in the state of Oregon.  Element Power, a Portland-based company obtained a conditional use permit from Lake County to build a 12-megawatt (MW) facility on approximately 100 acres of private land.  The solar electricity generated by the solar power project will be able to power 6,000 homes.

  According to Nicole Hughes, senior project manager with Element Power:

  “We’re hoping to get a power purchase agreement signed this year, then begin construction in the spring.”

  

  Utility scale solar can serve many households

  The approved solar power project in Christmas Valley will be located near an existing Bonneville Power Administration (BPA) power line.  This means the solar developer can save money and time connecting the power plant to the grid.

  The conditional use permit issued by the County grants approval for the proposed solar power project based on findings that the development will not harm endangered species, will be consistent with existing development in the area, and will otherwise be an appropriate location for this type of use.  Requiring a CUP (conditional use permit) is a way for permitting authorities to take a closer look at potential impacts and to require mitigating measures as part of the permit approval process.

  Permitting is not complete yet, however, as Element Power will have to obtain a Goal 3 exception under Oregon’s land use rules.  Currently, Goal 3 prohibits energy projects on more than 20 acres of low-value farmland (and 12 acres of high-value farmland).  However, with the CUP in hand and given the prime location for the solar power project, Element Power is likely to obtain the necessary state approval to proceed.

  Element Power has operations in the U.S., Europe, and South America. In the United States, has over 6,000 MW of wind energy and 1,000 MW of solar energy under development.

  Largest Solar Project on United States Public Lands Approved

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  

  Largest Solar Power Project Approved on U.S. Public Lands

  This week, a 1000-megawatt (MW) utility scale solar energy project was announced.  The largest solar project on U.S. public lands was approved for an area outside Blythe in the Mojave Desert in southern California.  The utility scale solar power plant will be called the “Blythe Project,” and will cover more than 7,000 acres of publicly-owned land near the California-Arizona border, about 225 miles east of Los Angeles.

  The solar project will be developed by Solar Millennium, a German solar developer, at a cost of $6 billion.  It is the 6th solar power development project approved by the U.S. Department of the Interior in October 2010, and another approval could be right around the corner.  Together, the seven solar power plants – all of which will be located in California and Nevada – will be capable of generating 3,000 megawatts of power.  That’s the equivalent of powering 2 million homes!  Clean solar electricity will be available from the projects by the end of 2011 or early 2012.

  More than just solar energy will be generated.  Construction of the solar projects on U.S. public lands will create over 2,000 jobs, and operation of the power plants will also require several hundred workers.

  

  Construction of a solar power projects will create many green jobs

  There are some that believe its about time these solar projects were approved on United States public lands.  Five years after the Bureau of Land Management (BLM) was asked for rights to develop solar plants on federal land in the desert Southwest, a system was finally established to cut through red tape and move through environmental review.  Currently, 14 of more than 180 solar power permit applications have been identified as the most promising and given “fast track” designation.

  As the projects are approved and brought online, more than 4 million homes will be able to run on solar electricity.

  Solar Powered Parking Meters in Los Angeles

   » ‎ Solar Power -- PV Panels

  Tags:    [edit]

  

  Solar Powered Parking Meters

  Solar powered parking meters, like the ones shown to the left, make perfect sense in sunny, Southern California.  Perhaps that’s why Los Angeles recently installed 10,000 new solar powered parking meters throughout the city.

  Manufactured by IPS Group, the electronic system inside the parking meters are powered by a solar panel on the rear of the device.  Wireless networking capabilities of the meters allow them to process credit and debit cards with a centralized meter management system that can approve transactions in real time. No more scrounging around for a few quarters to park (but if you prefer coins, the meters take those too!)

  The battery pack inside the solar powered parking meters are guaranteed to last 3 years before replacement.  According to the official website:

  The IPS Single Space Parking Meter is designed specifically to address the growing demand for multi-payment options on Single Space Parking Meters, including credit card, while offering all the ease and benefits of a traditional single-space meter.

  Installing the new solar powered parking meters is relatively easy, too.  Existing poles from traditional parking meters can be used to mount the new meters that run on solar energy.

  In Los Angeles, the City is already realizing income from the solar powered parking meters.  According to Mayor Antonio R. Villaraigosa the newly installed meters generated $230,000 in additional net revenue in September alone.  At that rate, the parking meters could help bring in up to $2.5 million annually, nearly double the original projections of the Los Angeles Department of Transportation.

  Because cities don’t have to pay up-front for the solar powered parking meters, the lower cost of a lease allows them to start bringing in increased revenue from the easy-to-use parking meters right away.

  You can find the solar powered parking meters in L.A., Denver, Washington, DC, and Eugene, Oregon.  IPS Group notes that its meters are in 45 cities across the U.S. and Canada.

  Solar panels on schools in California

  California is making some serious progress with respect to its solar energy goals!  This week, news that five California schools will go solar in the Huntington Beach School District in Southern California was announced.  The 618-kilowatt (kW) solar panel system will provide 1/3 of the school district’s energy needs through clean, renewable solar power.

  The Huntington Beach School District partnered with Chevron Energy Solutions to install solar panels at three elementary schools and two middle schools in the district.  Installation will take place in 2011, with Chevron Solutions operating and maintaining the solar panel system throughout the 15-year contract term.

  Solar is a smart investment for the California school district – even considering the cost of the installation, the district will save over $15 million in electricity costs.  What great lessons for the students, parents and teachers… math, science and social studies combining to show the possibilities of solar power to save money and the environment.

  Peel and stick solar panels

  Thinking about a home solar power system?  Worried about cost and time for installation?  With new “peel and stick” solar panels from Lumeta, installation of PV solar panels can be achieved in 1/3 less time.  No rack mounting and half the labor expense ordinarily required to install solar panels.  Without potentially damaging roof perforation, you can relax while you generate clean, free solar electricity.

  The PowerPly 400 uses photovoltaic (PV) thin film solar technology.  Basically, its a coating of solar cells on glass that, according to its website, “contains a DuPont™ Tefzel front sheet and fiberglass-reinforced plastic (FRP) substrate that allows module flexibility, yet provides the rigidity needed to assure module strength.”

  In addition to the easy installation of the peel and stick solar panels, weight of the solar power system is minimal.  PowerPly 400′s design is low-height, which also prevents water pooling at the base of the panels, saving your investment – and your roof.

  If you are interested in the peel and stick solar panels, you can get PowerPly directly from Lumeta in quantities greater than 250 kW.  Lumeta Inc. is one of four subsidiaries of DRI Companies, a California leader in roofing and solar technologies.

  The new airport terminal in Redmond, Oregon includes solar panels

  This year, the Redmond Airport in Central Oregon underwent a significant expansion that included the installation of new solar panels on the facility’s rooftop.  Now, passengers and other interested people can monitor just how much clean, solar electricity is generated each day at the with a new page on the airport’s home page.

  The solar power generation tracker is found at www.ci.redmond.or.us, by clicking on Airport Solar Panels Information.

  As of the date of this publication, here’s what the solar power generation tracker has to say about the solar energy at Roberts Field:

  

  In just two months of operation, the solar panels at the airport have generated enough solar electricity to offset nearly 800 gallons of gas.  The panels provide about 10% of the airport’s energy, but the overall expansion project included a number of efficiency upgrades, as well.

  As part of a $40 terminal expansion, the size of the airport was increased nearly 6 times its former size (from 23,000 square feet to 140,000 square feet); power needs only increased about 2.5 times, however.  The solar panel system at the Redmond Airport cost $550,000, but the airport only had to pay $27,500 due to federal and private grants.

  The solar power generation tracker webpage is a great resource for students, solar energy proponents and those that are just curious as to the amount of CO2 that is being offset by the solar panels at the Redmond Airport.

  Solar power from Jellyfish?

  When you think of jellyfish, what comes to mind?  Renewable energy?  Probably not, but researchers have discovered a way to get solar power from jellyfish.

  Jellyfish are some of the Earth’s most ancient organisms – even older than sharks.  Floating through the oceans without any internal organs, the creatures can reach sizes of more than 7 feet in diameter, with tentacles extending 120 feet into the depths below.  What use could these gelatinous bodies have for us?

  Glad you asked!

  A group of scientists from Sweden have discovered that jellyfish create a substance that can be used to increase the efficiency of solar cells.  More efficient solar cells mean a lower cost for solar panels, which could bring the renewable resource to more people worldwide.

  

  Proteins in jellyfish bodies can increase solar panel efficiency

  The bodies of jellyfish include a bioluminescent protein that includes a key ingredient, green fluorescent protein (GFP) which has the amazing ability to generate power.  In fact, a single drop of GFP placed on aluminum electrodes and then exposed to ultraviolet light (sunlight is comprised of UV rays) can produce measurable electrical current.

  According to a related article:

  Called biophotovoltaic nanodevices by their creator, these light-powered cells could replace Grätzel cells, which duplicate plant photosynthesis via chemicals like titanium dioxide, iodine and sensitizer dyes to produce a photoelectrochemical form of energy.

  Like algae, GFP can be a useful, natural substance to help boost the conversion rate of solar cells.  Lest you worry about the harvesting of innocent jellyfish, researchers are developing artificial GFP in the laboratory.

  No jellyfish were harmed in the writing of this article!

  Solar ivy to generate "green" electricity for your home?

  Solar energy is getting artistic.  Designers, artists and and architects are finding more and more ways to make green electricity attractive, as well as efficient.

  The latest entry in the solar art arena is a solar-wind hybrid invention called “Solar Ivy,” pictured above.  When the sun shines on the photovoltaic (PV) leaves, or the wind blows through them, clean renewable energy is generated.

  Created by Samuel and Teresita Cochran, a brother-sister team of Brooklyn-based SMIT (Sustainably Minded Interactive Technology), Solar Ivy is comprised of thin film solar over polyethylene.  Consumers will have the option of also having a piezoelectric generator attached to capture kinetic energy generated by breezes.

  Don’t head to your local hardware store looking for solar-powered ivy just yet, however.  The invention is still in the concept phase as developers work to lower the cost of the micro-generators.

  But don’t they look cool?!

  

  Close up of solar ivy "leaves"

  Solar Ivy has been making news, even if it isn’t yet climbing the sides of your home or office building.  It was featured at the MoMa Exhibition, Design Philadelphia, by Dwell on Design, and by the New York Times for its 9th Annual Year in Ideas issue (2009).

  At Design Philadelphia, the Cochrans installed Solar Ivy on a bus stop.  Can you imagine re-charging your phone or laptop with solar energy generated by mechanical leaves, while waiting for your bus?
