Evergreen Solar’s ES-Series String Ribbon solar panel, a product that that delivered the most kilowatt hours of electricity out of 14 competitors, is currently undergoing a yearlong test that will end in April 2009, conducted by TÜV Rheinland Group. Another test, conducted by PHOTON, also confirmed high ratings for the company, with the panels delivering 1038 kilowatt hours of electricity for the entire year.
Unlike other companies that can only guarantee initially 95-97% of the nameplate power rating, Evergreen’s solar panels guarantee 100%.
