California-based impartial engineering and certification take a look at laboratory Renewable Energy Test Center (RETC) has launched its “2025 PV Module Index Report,” which exams photo voltaic panels for reliability, efficiency and high quality.
This 12 months, RETC acknowledged 21 module producers for prime achievement throughout 14 testing sequences. RETC additionally recognized 12 producers as assembly the factors for its “Total Highest Achiever” recognition. The 12 producers are: Astronergy, DASolar, DMEGC, JA Photo voltaic, JinkoSolar, Longi, Runergy, SolarSpace, Trina Photo voltaic, VSUN, Waaree and Yingli Photo voltaic.
To be acknowledged as an Total Highest Achiever, producers should efficiently full RETC’s rigorous Thresher Take a look at program and excel throughout a number of exams inside the reliability and efficiency disciplines. Producers should additionally exhibit a dedication to high quality management and assurance by permitting an impartial third social gathering to randomly choose PV modules from stock for Thresher Testing.
RETC reserves Total Highest Achiever recognition for producers of payments of fabric (BOMs) that excel throughout three interrelated and equally influential disciplines: module reliability, efficiency and high quality. A step down from this prime honor, RETC acknowledges producers of merchandise that excel throughout a number of testing sequences inside one particular self-discipline for “Excessive Achievement in Reliability” or “Excessive Achievement in Efficiency.”
the 2025 report discovered a rise in points associated to humidity, thermal biking, PID and metastability. RETC additionally discovered structural points, like module body and glass failures throughout mechanical loading.
“Although some current bankability take a look at outcomes are alarming, these are additionally points that the technical due diligence group has efficiently eradicated prior to now or can resolve with improved take a look at requirements. As long as we have now eyes to see them, we are able to clear up these issues,” said Cherif Kedir, CEO of RETC.
