Even during Vermont's shortest days, the systems can collect enough energy to support their normal operation through 15 hour nights. This is partly due to algorithms built into the controller to monitor and adjust voltage from the solar module (Maximum Power Tracking).
US to Reach 12% Global Market Share by 2015
Despite a struggling domestic economy, the US solar photovoltaic (PV) market will double in 2011, according to the latest Solarbuzz® United States PV Market Report. 2011 growth rates vary significantly by market segment, an outcome of the vast movements in incentives and policies at the federal, state and local government level over the past 12 months. “With rapid declines in factory gate prices over the past eight weeks as manufacturers and distributors focus on depleting module inventories, demand has picked up across residential, corporate and government segments,” noted Craig Stevens, President of Solarbuzz. “This acceleration is being supplemented by explosive utility demand and the rush to install before federal cash grants are scheduled to expire at the end of the year.” The US is forecast to become the third-largest solar photovoltaic market, behind Germany and Italy in 2011. While the US currently comprises 5% of the world PV market, Solarbuzz projects an increase to 12% by 2015.
7 ways the military is embracing cleantech
The U.S. government is growing into one of the most important cleantech customers. It’s been investing and proselytizing the value of clean power, biofuels and energy efficiency products and services for job creation, energy security and (insert your favorite cliché here). And it’s a natural extension that it also should set an example as a major consumer of these technologies. The U.S. Defense Department, which uses 80 percent of the energy consumed by the federal government, is increasing its efforts to fund and use cleantech. A lot of these efforts are centered on drafting purchase plans and testing technologies in the field and one thing to consider is that larger companies might have an easier time convincing the military to buy than startups. Click here for a list of some of the military’s plans and projects .
Solar power plant switches to PV from thermal
Developers of the giant Blythe Solar Power Project in California have switched from solar thermal technology to photovoltaic solar panels, one of a string of similar changes at large-scale solar projects. Solar Millennium today said that the first 500-megawatt phase of the Blythe plant will use photovoltaic (PV) panels because the economics work better. The company earlier this year had received a conditional loan guarantee from the Department of Energy to develop a concentrating solar thermal plant, where heat from mirrored troughs makes steam which is passed through a turbine to generate electricity. But Germany-based Solar Millennium and its US subsidiary said it will use commercial financing and PV technology instead. Seven other utility-scale solar projects in the southwest U.S. have decided to scrap concentrating solar power (CSP) for PV. All told, that's about 2,515 megawatts of solar capacity that has converted, according to GTM Research analyst Brett Prior.
The moves underscore how falling costs have improved the competitiveness of PV for large-scale projects. Solar PV prices have fallen by more than 50 percent over the last two years, making them more attractive to both the energy developer and institutions putting up the money to finance these projects.

Biofuels Potential to Transform the Global Economy
The technology is in place, the product has been certified, and at the end of the day, one is talking about an agricultural product which, depending on where it is sown, can produce one or even two harvests a year.
Energy Storage Solutions
Energy storage is set to play a vital role in ensuring the economic viability of renewable energy by addressing its intermittency issues to make it available on demand. Equally, energy storage can play an important political role in the change to a low carbon economy by ensuring that the lights always stay on.

Evergreen Solar Files Chapter 11
Evergreen Solar shares are down more than 60% Monday after the company filed a Chapter 11 bankruptcy in federal court in Delaware. The stock seems likely to expire worthless. In connection with the filing, the struggling solar company said it reached a deal with holders of more than 70% of its outstanding 13% convertible senior secured notes to start a restructuring process that will include the sales of the company’s String Ribbon silicon wafer technology business. A company created by the noteholders called ES Purchaser will serve as a stalking horse bidder for the company’s assets. Evergreen said day-to-day operations will go on, and that it will continue to pay suppliers and vendors. As part of the reorganization, the company will cut 65 jobs in the U.S. and Europe, including suspension of operations at its Midland, Michigan plant. Here’s the nut of the story for investors: Evergreen said that “based upon the estimated value of the company’s assets, the assets are expected to be insufficient to satisfy all its obligations to its creditors. Accordingly, it is expected that no distributions will be made to holders of common stock and the common stock will be extinguished upon consummation of the Chapter 11 plan.”
A hybrid solar panel to make hydrogen
The best use of the sun's energy is to make hydrogen, according to a Duke University researcher. Engineer Nico Hotz earlier this week detailed results from his research around a rooftop solar panel that generates hydrogen from the sun's heat. The hydrogen gas--which is made by breaking off hydrogen atoms from a water solution--can be stored and used to make electricity in a fuel cell. In his experiment, Hotz determined that his system creates more usable energy than solar photovoltaic panels which convert sunlight directly into electricity. He calculated the cost could be lower, too. There have been research efforts--and a commercial product from a company called Nanoptek --to make hydrogen from sunlight. Hotz's system, though, uses a new technique that relies on methanol, also known as wood alcohol, and a nano-engineered catalyst. Under the glass of Hotz's solar collector are copper tubes, coated with aluminum and aluminum oxide, which carry water and methanol. Once the liquid is heated to a sufficient temperature, a catalyst is added to cause hydrogen atoms to break off. That hydrogen gas is then piped and pressured for storage in a tank, where it can be drawn on to make electricity in a fuel cell.
Ford EVs to come with household solar-panel option
Ford and solar-panel maker SunPower have created a solar-powered electric-car package. Buyers of Ford's electric vehicles will have an option to have SunPower's rooftop solar panels installed for about $10,000 after a federal tax rebate. The companies estimate that the 2.5-kilowatt array will generate enough juice, about 3,000 kilowatt-hours a year, to fuel acar for about 1,000 miles a month of driving.
The "Drive Green for Life" program means drivers can cut the cord on fossil fuels by generating power during the day and charging at night, according to the companies.
Ford plans to release an all-electric Ford Focus and its C-Max Energy plug-in hybrid in 19 states next year and in Europe in 2013.
The dangerous side of solar and wind power projects
They can look benign from a distance - solar panels glistening in the sun or turbines gently churning with the breeze to produce electricity for hundreds of thousands of homes. But building and maintaining them can be hazardous. Accidents involving wind turbines alone have tripled in the past decade, and watchdog groups fear incidents could skyrocket further - placing more workers and even bystanders in harm's way - because a surge in projects requires hiring hordes of new and often inexperienced workers. Last year, the solar industry grew 67 percent and doubled its employment in the U.S. to 100,000 workers, according to the Solar Energy Industries Association. The wind industry supports more than 75,000 jobs. "We're hearing about more and more incidents," said Lisa Linowes, executive director of watchdog organization Industrial Wind Action Group. "One of these days, a turbine's going to fall on someone." Many wind turbine technicians work in a bathroom-size space 20 stories above ground surrounded by high-voltage electrical equipment. Some inspect turbine blades while suspended alongside them, on sites whipped by strong winds. Components can weigh more than 90 tons.
