Testing lab Kiwa PVEL has printed its eleventh annual PV Module Reliability Scorecard. This digital useful resource offers photo voltaic business stakeholders with testing insights gained from Kiwa PVEL’s flagship Product Qualification Program (PQP). The PQP is a complete suite of prolonged reliability and efficiency assessments that consider photo voltaic modules below a variety of environmental and mechanical situations — together with the results of maximum temperatures and excessive humidity, in addition to the impacts of mechanical stress, hail and ultraviolet mild.

Within the eleventh version, Kiwa PVEL names a complete of fifty producers as “Prime Performers” in a number of of the assessments, with 9 producers named as Prime Performers with not less than one mannequin sort listed in every of the seven take a look at classes.
Different key highlights from the 2025 Scorecard embrace:
- Solely 21 mannequin sorts achieved Prime Performer standing in all reliability assessments (thermal biking, damp warmth, mechanical stress sequence, hail stress sequence, potential induced degradation and lightweight induced degradation + LETID), and of these, solely three fashions had been additionally Prime Performers in PAN.
- There are combined outcomes throughout PQP assessments, with some enhancing and others trending down. The PID and PAN outcomes improved, however the module breakage charge for MSS and HSS has elevated. Likewise, UVID outcomes are beginning to enhance, however are nonetheless a supply of concern for some.
- 83% of module producers had not less than one take a look at failure, up from 66% reported within the 2024 Scorecard, which on the time was the very best share ever reported.
“The fast tempo of innovation within the PV module panorama is encouraging, and it’s nice to see extra merchandise reaching Prime Performer standing,” mentioned Tristan Erion-Lorico, VP of gross sales and advertising and marketing at Kiwa PVEL. “Nonetheless, we proceed to warning consumers to not assume all modules are created equal. Our testing continues to uncover important variability in efficiency and long-term reliability. The Scorecard stays an important instrument for navigating these variations, serving to procurement groups make good, risk-conscious selections.”
The entire 2025 PV Module Reliability Scorecard is on the market on-line at scorecard.pvel.com. Utilizing the Prime Performers instrument permits customers to discover detailed take a look at outcomes, filter by producer, module sort, and take a look at class and obtain customized search outcomes for additional evaluation.
“Our 2025 Scorecard reveals each the progress and the challenges that include a dynamic PV module market,” commented Kevin Gibson, managing director of Kiwa PVEL. “For over a decade, we’ve rigorously examined modules to uncover reliability and efficiency traits, and this 12 months was no exception. Whereas not each take a look at end result exceeded our expectations, many did — demonstrating resilience and excellence in an evolving business.”
To be eligible for the 2025 Scorecard, producers should have accomplished the PQP pattern manufacturing manufacturing unit witness after October 1, 2023, and submitted not less than two factory-witnessed PV module samples to all PQP reliability assessments, as per Kiwa PVEL’s BOM take a look at necessities.
