LONGi named Top Performer by PVEL, the 6th year in a roll

China’s solar giant LONGi has been awarded "2022 Top Performer" in the annual PV Evolution Labs (PVEL) PV Module Reliability Scorecard. It is the sixth consecutive year the company has been honored by PVEL, a testing lab based in the US.

Based on PVEL's rigorous Product Qualification Program (PQP), the six tests included in the 2022 publication are 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, which strongly correlates to the performance in real life scenarios when analyzing modeled versus measured results for this accelerated lifetime test.


Top Performer status applies to model types with less than 2% degradation for the highlighted PQP reliability tests. For PAN performance, Top Performer status applies to model types 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," said Tristan Erion-Lorico, VP of Sales and Marketing at PVEL. "Not only that, but one of LONGi's models 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," said Steven Chan, general manager, North America, for LONGi.
