General Motors have the largest rooftop solar power array in the world on top of one of its factories in Spain.
When work finishes in 2008 the roof of Zaragoza assembly plant in Spain will be covered in 186,000 square metres of solar panelling with 85,000 solar panels, generating up to 12 megawatts of power.
The Zaragoza plant builds the Opel Corsa, Opel Meriva and the Opel Combo for Europe.
GM already has two of the largest solar power installations in the United States on the roofs of its Rancho Cucamonga and Fontana, Calif., parts warehouses. The solar panels on the Rancho Cucamonga warehouse provide about 50% of the facility’s electricity.
