TUV Rheinland Group, Newtown, Conn., has joined forces with Arizona State University (ASU), Tempe, Ariz., to create TUV Rheinland PTL, a state-of-the-art facility for testing and certification of solar energy equipment. This unique collaboration — a private venture based in Tempe — combines the powerful reputation, technological sophistication, management expertise and international reach of TUV Rheinland with ASU’s more than 50 years of research on solar energy and extensive solar testing know-how.

ASU’s Photovoltaic Testing Laboratory (PTL), established in 1992, has long been the only lab in the United States accredited for photovoltaic design qualification and type approval.
