June 21, 2007

Marlboro, Massachusetts, June 21, 2007 – Evergreen Solar, Inc. (Nasdaq: ESLR), a leading manufacturer of solar power products with its proprietary String Ribbon™ wafer technology, today unveiled its latest and most powerful PV panel. The new 195W model, part of Evergreen’s Spruce Line™ of PV panels, was unveiled at Intersolar 2007 (Booth F4.1.31, Hall 4), the world’s largest solar industry exhibition in Freiburg, Germany.

A product of Evergreen’s cutting-edge String Ribbon™ manufacturing technology, the 195W panel has the best available power tolerance (-0 / +2.5%), guaranteeing 100% of rated power. The new panel is qualified to meet all major industry certifications and regulatory standards. And Evergreen’s extensive and wide range of mounting options makes installation fast and easy.

“Our 195W model provides installers and integrators with a powerful, versatile panel to meet the continued rapid growth in the number and size of solar power systems worldwide,” said Dr. Terry Bailey, Evergreen Solar senior vice president of marketing and sales. “In addition to its performance advantages, the 195W is the most environmentally-friendly PV panel on the solar market today.” He noted that Evergreen’s new panel has the smallest carbon footprint and the quickest energy payback time available – benefits that reduce global warming and contribute significantly to energy conservation.  

Whereas many solar companies produce either wafers or cells or panels, Evergreen is a single company that produces all three under one roof at each of its manufacturing facilities. This gives Evergreen total control over every step of the production process to ensure the highest-quality products in the industry.
