Here's some video of Volkswagen's largest solar facility in the world at its US plant in Chattanooga. The Volkswagen Chattanooga Solar Park has a peak output of 9.5 megawatts and is the largest solar facility operated by an automaker in the USA.
The expected annual output of the about 33,600 crystal solar modules installed on an area of 13 hectares around the plant is about 13,100 megawatt-hours per year. The power is to be used directly in production, with solar power providing 12.5 percent of the electric power required in full-capacity operation and meeting 100 percent of demand when the plant is not in production.
Partners in the project are the Californian subsidiary of Phoenix Solar AG, Sulzemoos near Munich, and Silicon Ranch, headquartered in Nashville/Tennessee.
