“In an industry too young to have long-term field data on reliability, DNV GL’s comprehensive laboratory study goes beyond standard testing to bridge the knowledge gap and help minimize risk for solar investors,” DNV GL says in a press release.
DNV GL, the world’s largest resource of certification and energy expertise, has released the 2016 PV Module Reliability Scorecard, its second edition of a rigorous review of PV module performance. The study aims to address the lack of publicly available long-term data on reliability.
“While a 25-year performance warranty is standard in the industry, most PV modules have actually been in use less than five years, so there is a real lack of data on how equipment holds up over time,” said DNV GL’s Jenya Meydbray, the study’s lead author. “Since the first edition of the Scorecard in 2014, its findings have become a critical resource to an industry looking to understand risk.”
The Scorecard is intended to serve as a tool to compare module expected reliability and long-term performance qualitatively. The rankings provide a resource for banks, developers and independent power providers with findings to inform prudent investment in PV modules.
The 2016 Scorecard evaluated nineteen manufacturers, including more than fifty percent of the world’s 10 largest makers of PV modules. All participants in the study are commercially available products that have already demonstrated compliance with required safety standards. DNV GL tested five major factors affecting deterioration and reliability over time: thermal cycling, dynamic mechanical load, damp heat, humidity freeze and PID (potential induced degradation).
