“Evergreen Solar continues to produce String Ribbon solar panels and deliver more electricity with the lowest environmental impact at our U.S. manufacturing facility in Devens,” said Scott Gish, Evergreen Solar’s Vice President, Sales and Marketing. “As an American company and one of the largest solar employers in the United States, we recognize the importance of the American Recovery and Reinvestment Act in helping the U.S. economy and growing the number of jobs in this country. As the number of ARRA solar projects continue to increase across the U.S., our ES-A series panels will continue to be the panel of choice for American-based installers and end users.”

Also on display at Solar Power International will be its newest and most powerful ES-E Series solar panels featuring a 220w version. The ES-E series panels have an industry standard voltage of 29v which makes them micro-inverter compatible.
