First Solar installs 4.1 MW rooftop system

The Tempe, U.S.-based thin film manufacturer has installed a 4.1 MW system on the roof of its product testing and research facility at Mesa, fitted by California solar engineering firm Blue Oak Energy.

The 900,000 square-foot installation comprises almost 55,000 First Solar thin film modules which the company claims will account for the equivalent of 4,000 metric tons of CO2 per year.
