Modules becoming more powerful however witness increasing failure rates in 'year of successes' for PVEL's Module Reliability Scorecard

  • A total amount of 122 module types from 25 manufacturers have been named as "Top Performers" by PV Evolution Labs (PVEL) in its 2022 Module Reliability Scorecard, with some 'best ever results' in certain classifications as well as even more powerful modules being countered by poor performance in others locations.

The scorecard, released today and also now in its 8th year, presents searchings for from PVEL's PV Module Product Qualification Program (PQP), scoring solar modules complying with the results of numerous testing treatments, including thermal cycling, damp heat, backsheet durability, LID/LeTID sensitivity and also even more. In overall, there are 9 different groups assessed.

This year's Top Performers had more powerful modules than ever before, PVEL claimed, with wattages as high as 650W as well as an ordinary power course above 450W. Winning modules were based on 11 cell sizes from 156mm to 182mm and 210mm, which PVEL stated shown that "manufacturers can make reliable large-format PV modules".

On the other hand, a record 12 producers had one or more module types be Top Performers in every reliability test, with 6 of these version types also Top Performers in energy yield (PAN) performance.

"Suppliers overcame significant obstacles in the last year, and also contrasted to previous Scorecards, the 2022 results show that module technology is enhancing generally," kept in mind Tristan Erion-Lorico, VP of Sales as well as Marketing at PVEL.

Other key takeaways from this year's rankings show that while PVEL's thermal cycling (TC) results are "the most effective in PVEL's history"-- 90% of bills of materials (BOMs) evaluated deteriorated by less than 2%, with a median of 0.72% and also average of 0.97% --- it additionally observed "significant number of failures" when it involved mechanical test sequences.

In what PVEL called a "year of successes", it observed failures in testing, with just under fifty percent of all taking part makers experiencing a minimum of one failure, which is a significant get on last year's figure of 26%, up from 20% the year prior to.

Without a doubt, some groups fared much better than others. Damp warm (DH) tests that review the influence of warm and moisture on PV module reliability saw a "wide range of performance"-- 50% of BOMs attained top-performing results after the full test sequence, yet one BOM weakened by 54%, the most awful DH cause PVEL background, the testing business claimed.

The scorecard is made to supply empirical data for revenue and yield modelling, and assessment of new innovations as well as manufacturing techniques, benchmarking procedures as well as insight right into the upstream solar market.

Participation in PVEL's PQP as well as scorecard is voluntary for manufacturers and also just top-performing module model types are named in the scorecard. PVEL said that, to date, it has tested over 500 BOMs from more than 50 suppliers for the PV Module PQP.
