The new panel extends the EC-100 line of PV modules, providing 115 watts of output within the same size panel as its predecessors, the EC-94, EC-102 and EC-110.

MARLBORO, Mass., Oct. 6 /PRNewswire-FirstCall/ -- Evergreen Solar, Inc. (Nasdaq: ESLR), a developer, marketer, and manufacturer of photovoltaic (PV, solar electric) products for the worldwide market, will feature its newest PV panel, the EC-115, at the Solar Electric Power Association's UPEx 2003 Conference in Scottsdale, AZ from October 7-10.

The new panel extends the EC-100 line of PV modules, providing 115 watts of output within the same size panel as its predecessors, the EC-94, EC-102 and EC-110. Evergreen Solar introduced the Cedar Line(R) of photovoltaic modules in 2001. In addition, the EC-100 line introduced a new frame, which is stronger, but still compatible with existing products in the field.

"With the development of the EC-115, we've been able to increase solar panel efficiency by more than 20% in two short years," said Rex D'Agostino, Vice President of Marketing and Sales for Evergreen Solar. "And we're working on modules with even higher outputs. Evergreen Solar has a track record as one of the fastest-to-market companies in PV history, and this new panel helps to underscore the strength of our technology and how we're continuing to improve it."

All of Evergreen Solar's PV modules feature its patented String Ribbon(TM) technology that uses less silicon and energy to manufacture solar cells. This manufacturing process achieves the reliability, stability, high efficiency, and market acceptance of crystalline silicon -- without the inherent cost and waste of sawing solid silicon blocks. The technology was originally developed at MIT.

"Once again, this validates String Ribbon technology's strength," said Mark Farber, President and CEO of Evergreen Solar, Inc. "As we expand our capacity, producing panels with a higher wattage helps us continue to drive down the cost of production and moves us forward on the road to financial success. We're proud of how far we've come in such a short time, and we are moving forward steadily and surely."
