Evergreen Solar, Inc. (NasdaqGM: ESLR), a manufacturer of String Ribbon™ solar power products with its proprietary, low-cost silicon wafer technology, will introduce its ES-C Series String Ribbon solar panels, the company’s first-ever off-grid panels, at its booth during Solar Power International 2009 in Anaheim, Calif., October 27-29. Also showcased will be the company’s ES-A line of 200, 205 and 210 watt high output solar panels designed with its new black frame for increased aesthetics.

Evergreen Solar’s new line of ES-C Series off-grid panels and its ES-A Series on-grid panels will be available for viewing throughout Solar Power International at the company’s booth # 2001. Both product lines, like all Evergreen Solar panels, are manufactured using its proprietary silicon wafer technology which is the most environmentally-friendly process in the industry.

The ES-C Series of panels are suitable for direct 12, 24 or 48 volt battery charging in a wide variety of off-grid applications. The panels provide higher voltages for superior battery charging performance, particularly in hotter climates. Similar to the current line of Evergreen Solar panels serving on-grid markets, the ES-C line of panels deliver more electricity with the least environmental impact of any silicon-based solar panel currently available.

“The ES-C Series enables Evergreen Solar to capitalize on the expanding off-grid solar market and further positions the company as a leader in the global solar industry,” said Alan King, Director of Sales for the Americas. “Like all Evergreen Solar products this product line has been designed with differentiating performance characteristics to distinguish it from commodity-like competitors and provides better battery charging capability than other major brands. At the same time, we are proud to lead the industry in environmental credentials with the smallest carbon footprint and the quickest energy payback of any silicon-based panel available today.”

The ES-C Series panels are constructed with conduit-ready, multi-configuration junction boxes for easy, flexible installation. The panel’s double-walled, high-strength frame allows it to withstand the harshest of wind or snow conditions. The panels are also designed to fully comply with UL 1703 (for U.S. and Canada) and IEC standards (approval pending) and carry with them a five-year workmanship and 25-year power warranty. Evergreen is accepting orders now for initial shipments beginning in November. For more information call Alan King at 508-251-3301 or visit www.evergreensolar.com/ES-C
