GM Installs Largest Solar Power Plant
Capable of generating 12 MWs of electricity, GM’s solar panel installation on the roof of its factory in Zaragoza, Spain, once completed, will be the largest solar panel array in the world, covering over two million square feet. The panels are unique because they are flexible and are installed like carpeting. Or as they put it: a continuous web, multilayer, large-area thin-film amorphous silicon (a-Si) technology. Spain was chosen as the installation sight because of the subsidies its grants solar power. This installation is 5 times larger than the largest planned single installation in the United States. The company providing the system to GM, Energy Conversion Devices, has plans to have 1 gigawatt of solar generating capability by the year 2012. Southern California Edison has plans to develop a larger project, capable of 250 MWs, though it will be spread across 65 million square feet of rooftops in southern California.
