PVEL reveals top manufacturers in 2022 PV module reliability scorecard

By Editor


PV Evolution Labs (PVEL), a test lab for the solar and energy storage industry, has published its 2022 PV Module Reliability Scorecard, revealing 122 model types of PV modules from 25 manufacturers as Top Performers in PVEL’s testing.

#1 Jinko
#2 Trina Solar
#3 JA Solar
#4 Qcells
#5 REC Group
#6 Astronergy
#7 LONGi
#8 Adani Solar
#9 Maxeon / SunPower
#10 Phono Solar
#11 Seraphim / SEG Solar
#12 Suntech
#13 Vikram Solar
#13 Boviet Solar
#14 First Solar
#16 ZNShine
#17 Talesun
#19 ET Solar
#29 Heliene
#31 Risen Energy
#32 VSUN
#33 Waaree

The Scorecard provides insights for PV module procurement based on data from PVEL’s lab and field testing. It summarizes results from the PV Module Product Qualification Program (PQP), a testing regime established by PVEL in 2012 to provide empirical data for PV module benchmarking and project-level energy yield and financial models.

Notable findings in the 2022 Scorecard include:

A record of 12 manufacturers had one or more model types that were Top Performers in every reliability test – and six of these model types were also Top Performers in energy yield (PAN) performance.

This year’s Thermal Cycling results were the best in PVEL’s history: 90 percent of modules tested degraded by less than 2 percent.

There was a wide range of performance in Damp Heat testing: 50 percent of modules achieved top-performing results after the full test sequence, but one module degraded by 54 percent, the worst DH result in PVEL history.

In a year of successes, PVEL also observed failures in testing. Just under half of all participating manufacturers suffered at least one failure.

“Manufacturers overcame significant challenges in the last year, and compared to previous Scorcards, the 2022 results show that module technology is improving overall,” noted Tristan Erion-Lorico, VP of Sales and Marketing at PVEL. “PVEL’s Scorecard showcases impressive examples of product performance and reliability across our rigorous testing program, allowing buyers to easily identify high-quality modules.”

Participation in PVEL’s PQP and Scorecard is voluntary for manufacturers and only top-performing module model types are named in the Scorecard. To date, PVEL has tested over 500 BOMs from more than 50 manufacturers for the PV Module PQP.

The Scorecard is publicly accessible in an interactive digital format, with a searchable database of Top Performing modules at www.modulescorecard.pvel.com. A downloadable PDF summary is available.
