Evergreen Solar Launches New Line of Solar Panels for the Off-Grid Market

Features 80, 120, and 125W panels providing better battery charging capability than major competitors

MARLBORO, Mass.--(BUSINESS WIRE)--Sep. 11, 2009-- Evergreen Solar, Inc. (Nasdaq: ESLR), a manufacturer of STRING RIBBON™ solar power products with its proprietary, low-cost silicon wafer manufacturing technology, today introduced its new ES-C Series solar panels, designed to substantially expand the company's offering for the global off-grid market. This new line of 80, 120 and 125 W panels will be manufactured by Evergreen Solar's contract manufacturing partner, Jiawei Solarchina Co., Ltd., using cells supplied by Evergreen Solar.


The ES-C Series of panels are suitable for direct 12, 24 or 48V 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 Dr. Terry Bailey, Senior Vice President, Marketing and Sales. "Like all Evergreen Solar products this product line has been designed with differentiating performance characteristics to distinguish them 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 October. For more information visit www.evergreensolar.com/ES-C.

GreenFasten™ solar panel roof mount hardware, watertight, USA made

The GreenFasten™ - GF1 system utilizes the patented watertight technology EcoFasten Solar® is known for. The flashing is fit with our EPDM rubber bushing and when used with a compatible EcoFasten Solar compression bracket (milled with countersink), a watertight seal is created, which protects the integrity of the roof. Requiring just a single fastener (lag bolt or self-drilling), GreenFasten provides the fastest install in the industry and will not void roofing manufacturer's warranties. Backed by IAPMO certification, GreenFasten delivers a mounting solution for all new or existing (retrofit) composition shingle roofs, and is the most cost-effective solution available. Like all of the solar roof mount solutions in our line of products, GreenFasten is made in the USA using recycled materials.
