The San Jose lab is also undergoing a 13,500-square-foot expansion, which will provide 35% more space to current PV testing operations by July and result in project capacity growing an additional 30% year-over-year compared with July 2008, according to UL.

UL says it is the only National Certification Body for PV product testing in North America that is able to test and certify products in accordance with both UL Standards and International Standards (IEC).
