Jiawei Solar to manufacture off-grid module for Evergreen Solar

Jiawei Solarchina Co., Ltd.'s contract partner - 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. Evergreen Solar designed the products for the global off-grid market. Jiawei Solar will use cells supplied by Evergreen Solar to manufacture this new line of 80, 120 and 125 W panels.

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 also provide higher voltages for superior battery charging performance, particularly in hotter climates. The ES-C line panels deliver more electricity with the least environmental impact of any silicon based solar panel currently available.

The ES-C Series panels are constructed with conduit-ready, multi-configuration junction boxes for easy and 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 certified 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.

"Jiawei has rich experiences of producing off-grid solar panels with Evergreen Solar silicon cells; we believe we can work with Evergreen Solar to produce high quality and cost effective ES-C Series solar panels for off-grid applications." said Nancy Chau, Vice President of Sales of Jiawei Solar.
