Evergreen Solar, Inc. (Nasdaq: ESLR), a manufacturer of String Ribbon® solar power products with its proprietary silicon wafer technology, announced today its ES-A and ES-E series solar panels are some of the first panels to be certified for ammonia gas resistance by TÜV Rheinland.

The ES-A and ES-E series are high quality String Ribbon® solar panels offering exceptional performance, industry-leading environmental credentials and the ability to be installed in almost any climate or location. Back in 2010 the panels passed the rigorous IEC 61701 salt mist corrosion testing for PV panels. This newest certification confirms that the ES-A and ES-E series panels are now ideal for installations susceptible to potential damage from high concentrations of ammonia gas generated by livestock inside enclosed structures like barns.

“This ammonia gas resistance certification extends the ability of Evergreen Solar panels to be installed virtually anywhere that solar power is viable, and makes our powerful, environmentally-friendly solar panels available to more people,” said Mike El-Hillow, Evergreen Solar’s President and CEO. “These panels are already certified for use in climates which have snow or high winds as well as for installations susceptible to sea mist in coastal areas or on islands. We are now proud to have one of the first solar panels available in the industry tested by TÜV Rheinland to meet the draft standard IEC 62716 certification. This feature is extremely beneficial for those customers in the agricultural industry particularly focused on raising livestock including pigs and cattle.”

All Evergreen Solar String Ribbon solar panels are constructed using its proprietary wafer manufacturing technology which is the most environmentally-friendly process in the industry with virtually no wasted silicon. The carbon footprint of these panels is up to 30% smaller than that of its competitors. These solar panels also have the quickest energy payback, now as fast as 12 months for installed panels.
