United Solar Ovonic of Auburn Hills, MI, has teamed with Centria, a major roofing company, to create a metal roof system that integrates easy-to-install, flexible thin-film amorphous-silicon photovoltaic modules.

The partnership offers seven different prefabricated systems, ranging in capacity from 3 to 120 kilowatts, and could pay for itself in less than 10 years, Centria says.
