New Jersey is the nation’s second largest solar market behind California thanks to the state government’s commitment to increase the amount of electricity derived from renewable energy sources over the next decade.

But where are the other leaders in solar energy?

Here, courtesy of the Solar Energy Industries Association, is a Top 10 list for cumulative installed solar capacity in the United States as of 2010.

1. California: 47 percent with 971 megawatts

2. New Jersey: 14 percent with 293 MW

3. Colorado: 5 percent with 108 MW

4. Arizona: 5 percent with 101 MW

5. Nevada: 5 percent with 97 MW

6. Florida: 4 percent with 73 MW

7. New York: 3 percent with 54 MW

8. Pennsylvania: 3 percent with 54 MW

9. New Mexico: 2 percent with 45 MW

10. North Carolina: 2 percent with 42 MW

Department of Energy Awards 3M $4.4 Million to Reduce Cost of Photovoltaic Energy Systems

The U.S. Department of Energy (DOE) has awarded 3M $4.4 million as part of DOE’s SunShot Initiative. SunShot aims to reduce the total costs of photovoltaic solar energy systems by about 75 percent, so that they are cost-competitive with other forms of energy without subsidies. SunShot calls for achieving this goal by the end of the decade. The sum of the 3M award is estimated at $4.4 million over three years.

The goal of 3M’s project is to accelerate efforts toward further development and commercialization of 3M™ Ultra Barrier Solar Film. The funding will support a reliability test program to validate the lifetime performance of the film as well as development of second-generation 3M Ultra Barrier Solar Film with enhanced performance and reduced costs.

As part of the initiative, 3M will collaborate with DOE’s National Renewable Energy Laboratory (NREL) to test the performance and durability of Ultra Barrier Solar Films. NREL recently confirmed moisture vapor transmission rates in the range of 2*10-5 – 8*10-5 g/m2/day for 3M’s current Ultra Barrier Film 9L product using its electrically based calcium moisture vapor transmission rate (MVTR) test. “Technology for economical production of transparent barrier films has been a missing link in the flexible CIGS photovoltaic supply chain for a long time, and we are looking forward to working with 3M in the development of this technology,” says NREL senior scientist Mike Kempe.

“We are delighted that DOE has recognized the relevance of 3M’s Ultra Barrier Solar Film toward achieving its goals for driving down the cost of solar,” says Derek DeScioli, business development manager for the 3M Renewable Energy Division. “High-efficiency flexible solar modules manufactured with 3M’s Film not only have the potential to significantly reduce the total system costs for rooftop solar installations, but also have an array of niche applications where our customers can take advantage of the unique module form factor.”

Designed to address the needs of flexible thin film solar manufacturers, 3M Ultra Barrier Solar Film acts as a replacement for glass with high light transmission, moisture barrier performance and strong  weatherability.

New US Solar thermal plant approved after 20 years

02/09/2010 Comments off

The State of California has granted approval for a new solar thermal power plant. The 250-megawatt Beacon Solar Energy Project is the first solar thermal power plant to be licensed in the United States in nearly 20 years. Commercial operation is expected to start by the third quarter of 2011.

The Solar Wave Pavilion by Michael Jantzen

Paying homage to the extinct Mastadon, the Solar Wave Pavilion is Michael Jantzen’s attempt to design an eco-friendly structure that uses a variety of alternative energy sources.

The wavy roof will gather solar energy and provide as a storage system which can then be transferred to the grid. The wavy roof allows the photovoltaic cells to capture energy most efficiently.

The structure is open to provide a park-like setting for the community which it serves.
