LONGi named ‘Top Performer’ in PV Evolution Labs 2022 Module Reliability Scorecard


LONGi has been awarded “Top Performer” status in the 2022 edition of the annual PV Evolution Labs (PVEL) Module Reliability Scorecard – the sixth consecutive year that the company has received this recognition.

For the last eight years, PVEL’s Scorecard has provided the solar industry with crucial knowledge regarding long-term module reliability and performance data. Based on the organisation’s rigorous Product Qualification Program (PQP), the battery of tests included in 2022 were thermal cycling, damp heat, mechanical stress sequence, potential-induced degradation (PID), light-induced degradation (LID), light and elevated temperature-induced degradation (LETID) and PAN performance,  strongly correlating to real world performance when analyzing modeled versus measured results for this accelerated lifetime test regime.

Top Performer status applies to module types with less than 2% degradation in the highlighted PQP reliability tests. For PAN performance, Top Performer status applies to modules achieving a top quartile energy yield on the simulated PV sites presented in PVEL’s PAN reports.

“With six consecutive Scorecard appearances, LONGi continues to demonstrate quality, reliability and performance in its PV modules through PVEL’s testing,” commented Tristan Erion-Lorico, VP of Sales and Marketing at PVEL. “Not only that, but one of LONGi’s modules was named a Top Performer in all six testing categories—a rare feat.”

“LONGi prides itself on maintaining the highest standards of quality and reliability, and being named a Top Performer in PVEL’s Module Reliability Scorecard confirms our commitment,” added Steven Chan, general manager, North America, for LONGi. “Independent testing like that provided by PVEL is critical to the successful acceleration of the clean energy transition, and we are happy to help drive industry excellence with our high-performance solar modules that push the envelope in terms of innovation.”

PVEL will be hosting the PV ModuleTech—U.S. Special Edition conference on June 14-15 at its new Napa, CA, headquarters. LONGi will be speaking at the event, discussing why quality and bankability are crucial to high performance and reliable PV systems.
