EverQ Opens Second Major Manufacturing Plant

June 19, 2007

Production at German site triples to nearly 100MW

Thalheim, Saxony-Anhalt, Germany, June 21, 2007 – EverQ, a manufacturer of Evergreen Solar-branded solar panels, recently marked another milestone in its rapid growth with the June 19 opening of a second factory in Thalheim, Saxony-Anhalt, Germany.  The new 60-MW facility began operations just one year after the opening of the first EverQ production plant at the same location.

The expansion increases the joint venture’s manufacturing capacity of 30MW by another 60 MW. By the end of the year, the workforce at the new plant will number 450, growing EverQ’s total employment to approximately 800. The German state of Saxony-Anhalt provided funding for construction, infrastructure and personnel costs related to the first EverQ facility in 2006.

EverQ is an equal partnership of three global leaders in the solar power industry: Evergreen Solar, Inc. (United States), Q-Cells AG (Germany), and Renewable Energy Corporation ASA (REC) of Norway. Evergreen develops, manufactures and markets solar power products using its proprietary String Ribbon™ technology. Q-Cells is the world's largest independent manufacturer of crystalline silicon solar cells. REC is the world's largest manufacturer of solar-grade silicon and multicrystalline wafers to the solar industry and also operates within solar cells and modules.

The partnership uses Evergreen Solar’s unique String Ribbon™ wafer technology to manufacture its high-quality products. Whereas many solar companies produce either wafers or cells or panels, EverQ produces all three under one roof. This gives the manufacturer total control over every step of the production process to ensure the highest-quality products. All of the panels produced by EverQ are Evergreen Solar-branded Spruce Line™ products, which Evergreen uses to supply its customers in Europe and around the globe.

“The opening of EverQ 2 keeps us on schedule with our joint venture’s aggressive expansion plan to increase production to 300 megawatts by 2010,” said Rick Feldt, President and CEO of Evergreen Solar. “The global market for solar power remains very strong. We’re pleased to have high quality products to provide our customers in markets throughout the world.”

Anton Milner, Chief Executive Officer of Q-Cells AG, is also pleased with EverQ’s success. “Each partner’s unique expertise, technology and resources are what make our joint venture such an impressive achievement. The speed with which EverQ tripled its manufacturing capacity is remarkable. It makes our decision to locate in Germany – with its strong government support and a high-skilled workforce – the right choice.”

“EverQ has already achieved our common goal to manufacture high-quality products,” said Erik Thorsen, CEO of Renewable Energy Corporation ASA. “Our focus now is on harnessing our manufacturing efficiency and abundant supply of polysilicon to increase production rapidly. Ultimately, our growth and continued focus on cost aim to make solar power competitive with retail electricity pricing.”
