For eight years running, PVEL’s PV Module Reliability Scorecard has provided the solar industry with crucial knowledge about long-term module reliability and performance data.
Based on PVEL’s rigorous Product Qualification Program (PQP), the battery of 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 real world performance when analyzing modeled versus measured results for this accelerated lifetime test regime.
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. “Independent testing like that provided by PVEL is critical to the successful acceleration of the clean energy transition, and we are honored to help drive industry excellence with our high-performance solar modules that push the envelope in innovation.”
