Energy Conversion Devices, Inc. (EDC) announced that its UNI-SOLAR thin-film flexible solar laminates will power the world's largest rooftop solar power system. A 12-megawatt system is being installed on GM's assembly plant in Figueruelas, Zaragoza, Spain and will become operational in the fall of 2008.
When fully operational, the photovoltaic system will have a peak capacity of 12 megawatts, producing as much as 15 million kilowatt hours of "green" energy annually, enough to power approximately 4,500 homes. The Zaragoza facility marks the third major use of UNI-SOLAR laminates by GM. UNI-SOLAR thin-film flexible solar laminates also power GM parts warehouses in Rancho Cucamonga and Fontana, California, two of the largest rooftop solar power installations in the United States. GM partnered with Veolia Environnement, Clairvoyant Energy S.L., and the Government of Aragon to develop the Zaragoza renewable energy project. GM will lease its roof space to Clairvoyant Energy and Veolia Environnement, who will build, own and operate the rooftop solar installation.
