Los Angeles-based Solar Integrated Technologies today announced it had signed a deal with British supermarket chain Tesco to install the "world's biggest" roof-top solar panel set-up.

The $13m contract will provide eco-friendly juice for Tesco USA's new distribution center in Riverside, California. According to Solar Integrated supremo R. Randall MacEwen, the panels will "provide a fifth of the depot's power supply" while saving "1,200 tons of carbon dioxide emissions each year".

The installation, covering 500,000 square feet on two buildings, will generate 2.6 million kilowatt hours per year. It's expected to be up and running this year. ®
