Evergreen Solar Introduces Spruce Line of Solar Panels

50% More Powerful Than Its Cedar Line

Marlboro, Massachusetts, USA, April 21, 2006 - Evergreen Solar, Inc., a manufacturer of solar power products with its proprietary, low-cost String Ribbon' wafer technology, today introduced the Spruce Line' of photovoltaic panels. The new Spruce series are approximately 50% more powerful than the Company's Cedar Line' panels.

The Spruce Line includes 170W, 180W and 190W panels. With a sealed junction box, factory-installed electrical connectors and 1000-volt-rated backskin, these panels are ideal for grid-connected or larger off-grid applications.

The 190W model offers 12.7% module efficiency, a substantial increase from Cedar panels. The Spruce Line offers several other improvements that boost power rating and energy performance including higher packing density, anti-reflective-coated glass and higher-efficiency solar cells. The coated glass improves both rating at Standard Test Conditions as well as average field energy performance. As with the Cedar Line, Spruce panels have a white backskin for higher internal reflection and cooler operation.

Just like the Cedar Line, all Spruce panels are tested at Evergreen Solar's factory to a stringent -2% peak power (Pp) rating at Standard Test Conditions. Spruce products will have the following safety and quality certifications: IEC 61215 Edition 2, UL Class C Fire Rating, TÜV Safety Class II and CE.

Evergreen Solar panels use solar cells produced by the Company's String Ribbon manufacturing process. String Ribbon is substantially more efficient in the use of silicon than conventional sliced crystalline technologies.
