By measuring and monitoring solar thermal system performance, installers can correct mistakes and fine-tune and optimize systems. As a result, US consumers are likely to regain confidence in the technology, spurring what is expected to be a burgeoning market for solar hot water heaters.
MicroCSP power projects all include sun tracker and thermal storage. The cost is around the same as PV but you generate more electricity per day because of the tracker/storage combination so you have a lower cost of energy.
Recent advances in materials science have led to the development of innovative new materials that provide enhanced durability to photovoltaic modules. Unique polymeric thin film technologies, such as ethylene-tetrafluoroethylene (ETFE) frontsheets, provide modules with the protection they need to perform at high levels even when exposed to the elements.
Research has shown that LEED buildings consume over 25% less energy, have 13% lower maintenance costs, 27% higher occupant satisfaction and a 33% reduction in GHG emissions compared to the average commercial building.
Bard College and Hawthorne Ridge Retirement Community are two examples of down to earth solar energy projects that make a difference.
Developing biofuels continues to be a bright spot in the cleantech world. Two startups, plant genetic engineering company Chromatin and biofuel producer ZeaChem, announced separately on Tuesday that they have raised new rounds of funding. Chicago-based Chromatin said it has lined up $10 million – the first close of the D round – from investors including the venture arm of oil giant BP and the investing arm of product firm Unilever. Chromatin has developed a technology to genetically modify energy crops so that they grow fast and abundant, and its plant of choice if sorghum, a grass with some desirable, natural characteristics as a bioenergy feedstock, such as a high tolerance for drought and heat.
Like Detroit automakers taking on the Japanese a generation ago, the seven American solar panel makers that filed a trade case on Wednesday against China might find that a legal victory, if it comes, may not translate into business success.In the 1970s and ‘80s, American car companies won a long series of trade cases to limit Japanese car imports. Japan’s automakers responded by moving assembly lines to the United States, creating many new blue-collar jobs. But they kept most of the high-paying design and engineering positions back in Japan. The new factories in the United States not only shielded Japanese auto companies against most further trade protectionism but helped them stay competitive when the yen soared against the dollar. Meanwhile, American consumers had many new, affordable choices in cars — while Detroit continued to have trouble competing with its Japanese rivals. Don’t be surprised if Chinese solar companies try to pursue a similar path, which could benefit American consumers of solar power if it helps propel the technology beyond its current niche status.
Solar Power International 2011 took place in Dallas, Texas, with a goal to generate powerful new ideas, connections and business opportunities for the solar industry. An estimated 24,000 professionals and over 1200 exhibitors from businesses spanning the entire spectrum of the industry will be on hand for four days of product exploration, discussion, professional enrichment and networking. The AltEnergyMag team has taken some time to put together a list of some of the interesting new products and services seen at this year's show.
The Solar Foundation, a nonprofit solar education and research organization, today released its second annual review of the solar workforce in the United States. The report, titled, "National Solar Jobs Census 2011: A Review of the U.S. Solar Workforce" found that hiring in the solar workforce is on the rise. More than 100,000 Americans are now employed in the solar industry. "The solar industry has grown into a major economic force with more than 100,000 employees in the United States," said Andrea Luecke, executive director of The Solar Foundation. "We expect even greater growth in the foreseeable future. But policymakers, workforce training providers, and the industry must work together to continue creating good jobs for skilled workers." As of August 2011, the National Solar Jobs Census 2011 identified more than 17,198 solar employment sites and 100,237 solar jobs in all 50 states. The solar industry's job growth rate of 6.8 percent is significantly higher than the 2 percent net job loss in fossil fuel power generation and the economy-wide expectation of 0.7 percent growth over the same period.
Solar Power International 2011, October 17-20, is in Dallas, Texas to generate powerful new ideas, connections and business for the solar industry—and your enterprise. 24,000 professionals from businesses spanning the entire spectrum of the industry for four days of product exploration, discussion, professional enrichment and networking.

Many of the cutting edge thin-film technologies require rare elements that are a finite resource already in short supply. There simply is not enough material on the planet to make these devices for worldwide consumption.
Under the terms of a solar PPA, a solar services provider installs solar equipment at a host business, government site, university, or other organization, and the host agrees to buy the solar electricity generated by the system for a fixed price and term, usually 5-20 years.
I wrote this article for HomeToys.com, our Home Technology website but it applies to Alternative Energy as well. It's not enough to monitor our energy use. We don't really care about that unless it does something to change our lives or save us money. So, let's put a solar system on the roof. Now that can do both of these things and should attract our attention. But let's take it a step further. With that solar system there is a new variable in the mix --- FREE CLEAN ENERGY. What can and should we do with it.
The Denver recently reported the NREL was going to lay off 10 percent of its employees. It took about two light seconds for a popular Washington D.C. news site to pronounce the layoff a "scandal," because NREL had taken federal stimulus money. That is silly. NREL, of course, is where the Department of Energy tests and develops new materials and techniques for solar, wind and other kinds of energy.
Harvest uses a platform of technologies - including advanced composting, anaerobic digestion, and material recovery - to harness the full carbon, energy and nutrient value from discarded organic materials.

Eliminate Solar Rack Ballast and Reduce Rooftop Material Handling. PowerGrip™ Universal (PGU) is a commercial roof mount system designed to secure solar racks and other equipment to any type of commercial roofing system. PGU provides a secure connection directly to the roof deck or structural members and is designed to reduce or eliminate ballast in solar racking systems, so there's less weight on the roof and less material handling. Made of heavy-duty cast aluminum, PGU units include a base ring which is secured through the roofing cover and into the structural roof deck, and a waterproof top plate.
