Top Performers

Every year, our Scorecard recognizes manufacturers that produce PV modules with excellent results in PVEL's independent testing.

Rankings are based on performance and reliability data from the PVEL PV Module Product Qualification Program, a suite of lab and field tests that inform solar procurement and investment decisions.

122 top performing model types

122 model types from 25 manufacturers are named as 2022 Top Performers for their superior results in PVEL’s Product Qualification Program.

Higher power classes

This year’s Top Performers pack more power into every module than ever before, with wattages as high as 650W and an average power class greater than 450W.

11 cell sizes

2022 Top Performers include models based upon eleven cell sizes from 156 mm to 182 mm and 210 mm, proving that manufacturers can design reliable large-format PV modules.

All star results from 12 suppliers

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 PAN.

Resilience of Manufacturers

Manufacturers overcame significant challenges last year, from instability in the raw material supply chain to logistics bottlenecks. Explore examples of resilience from Alex Barrows, Head of PV at Exawatt.

Raw Material Challenges: PV Glass

In late 2020 PV glass prices spiked, with spot prices nearly doubling between July 2020 and December 2020 for many reasons including:

  • Increased demand for glass//glass modules.
  • Temporary production declines as manufacturers shifted to thinner glass.

However, glass manufacturers rapidly resolved manufacturing issues and ramped up new capacity. Prices dropped in early 2021 and have since remained relatively stable, despite continued production challenges.

Shipping Challenges: More Power per Container

Since early 2020, average global ocean shipping costs have increased by around 600%. Shipping costs from China and Southeast Asia to the West Coast of the U.S. spiked by >10x.

But the trend toward larger PV wafers can partially offset higher costs. Modules based on 182 mm and 210 mm wafers have average packing densities around 40% higher than those based on 156.75 mm wafers.

Manufacturers of 210 mm-based modules significantly improved packing density during the past year, with the average power per 40’ (12 m) high cube container jumping to >340 kW in Q1 2022, an increase of almost 20% from 12 months earlier.

“We are proud to be recognized as a PVEL Top Performer for the eighth consecutive PV Module Reliability Scorecard. Trina’s consistent and exemplary performance in PVEL’s rigorous independent testing is accepted by the market as clear evidence of our long-standing commitment to product quality.”

Helena Li, President, Global Module & Cell Business, Trina Solar


We use a consistent methodology for testing and ranking PV modules: the Product Qualification Program. Our process helps buyers compare products consistently from year to year and Scorecard to Scorecard.

Our testing goes beyond the model types of PV modules to assess bills of materials. This approach ensures buyers can procure the specific products that we have validated in testing.


In a year of successes, PVEL also observed failures in testing for the PV Module Product Qualification Program. While fewer manufacturers experienced a failure this year as compared with the 2021 Scorecard, one quarter of BOMs suffered at least one failure during testing. The greatest number of failures occurred during the damp heat sequence. Explore 2022 failure data to learn more.
