After months of testing, Trina Solar was once again recognized as a “Top Performer”, 2022 by PV Evolution Labs (PVEL), an internationally renowned third-party reliability testing lab. Trina Solar is now the company with the most wins. This is the eighth consecutive recognition. This recognition highlights Trina Solar’s dedication to high-quality consistency, high reliability, and exceptional safety of its modules. PVEL has published test results that show the 670W Vertex modules with ultra-high power (210mm) have the highest performance in PQP sequences.
PVEL reviews PV modules each year, using reliability and quality parameters that are much more stringent than the IEC standard. The PV Module Reliability Scorecards are published on a year-end basis by PVEL, which provides the solar industry with reliable, consistent reliability data and benchmarking data.
The PQP includes test sequences for thermal cycling, damp heat, backsheet durability, and mechanical stress. The damp heat test duration and thermal cycles are twice the IEC standard requirement or even more. The new Mechanical Stress Sequence (MSS) combines tests for static mechanical load, 1,000 cycles of dynamic mechanical load, 50 thermal cycles, and 10 cycles of humidity freeze. Modules passing the PVEL-PQP tests naturally meet reliability requirements in a variety of extremely demanding environments.
According to this year’s reliability and performance test results of PVEL, the Vertex modules of Trina Solar, from the Vertex S 410W for the residential scenarios to the 600W+ ultra-high-power modules for large ground-mounted power plants, have shown excellent reliability in all rigorous PQP tests.

In particular, the ultra-high-power Vertex 670W modules have achieved top performance in the PQP sequences for damp heat, thermal cycling, potential-induced degradation, LeTID sensitivity, and MSS. This means that the modules have excellent reliability and performance in harsh climate regions with high temperatures, high humidity, and large temperature fluctuations.
Notably, the MSS test results demonstrate almost no micro-cracks occurred in the BOMs tested for Trina Solar’s bifacial 670W modules, and the power degradation was less than 2%. In summary, Trina Solar’s ultra-high power modules in large format meet the Top Performer criteria defined by PVEL, maintain top performance and ensure mechanical reliability.
“On behalf of the entire PVEL team, I congratulate Trina Solar for achieving excellent test results on their 210 mm modules and being named as a PVEL Scorecard Top Performer for a record-setting eight consecutive years,” stated Tristan Erion-Lorico, VP of Sales and Marketing at PVEL. “Of particular note is Trina Solar’s Vertex 600W+ bifacial modules, which achieved Top Performer status in all five reliability tests. This is just the latest example of Trina Solar’s ability to manufacturer reliable modules over the past many years.”
Helena Li, President of Cell and Module Business, Trina Solar, commented: ‘PVEL is the world’s leading PV module reliability testing laboratory, which provides independent performance data. 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 are accepted by the market as clear evidence of our longstanding commitment to product quality. We believe PVEL’s this testing result is of great value to solar project developers, financiers, and asset owners and operators around the world.’
