Southern California Edison plans to install a huge network of solar cells, 10 times bigger than any previous such installation, on more than 100 large rooftops around Southern California. The solar panels, covering more than two square miles of rooftop, will be able to produce 250 megawatts of electricity when the sun is shining, enough to power about 160,000 homes.
Edison’s order is roughly equal to all the solar cells produced in the United States last year.
Edison is under orders from the state if Califonia to produce 20 percent of its power from renewable sources by 2010.
The largest solar installation in this country is 14 megawatts, at Nellis Air Force Base in Nevada. The largest in the world, in Spain, is 23 megawatts. Of the top 10 worldwide, all are in Spain or Germany, except for Nellis.
