For the 3rd consecutive year, LONGi Solar, a world leading mono-crystalline PV module manufacturer, has been named “Top Performer” in the annual PV Module Reliability Scorecard published by PV Evolution Labs (PVEL) and DNV-GL. This ranking summarizes the results of independent testing conducted as part of PVEL’s Product Qualification Program (PQP) and identifies the PV module models that achieved top performance
The PQP is a unique protocol of tests that generate empirical performance and reliability data, contributing to critical technical due diligence, energy forecasts and financial models utilized by solar investors and project developers. Manufacturers voluntarily participate in the PQP, but only “Top Performers” are eligible for listing in the Scorecard. Manufacturers choose to be recognized in the Scorecard in order to demonstrate the quality of their products to the market.
Testing for reliability and performance
According to PVEL, while IEC and UL certifications are important indicators of module safety, long-term reliability and performance are also important to PV buyers. By extending IEC 61215 sequences and incorporating additional tests, the Scorecard approximates the impact that decades of exposure in the field has on PV modules.
The Scorecard employs four demanding test sequences that stimulate PV modules long-term performance in real world conditions. It is today the most complete publicly available comparison of PV module reliability test results.
LONGi was named “Top Performer” in all four test categories:
- Thermal cycling.
- Damp heat.
- Dynamic mechanical load sequence.
- Potential induced degradation (PID).
LONGi hallmarks: technology innovations and product quality
DNV-GL PV Module Reliability Scorecard “Top Performer” status is validation of the reliability of LONGi high efficiency PV modules and demonstrates the company’s R&D technology leadership and quality-first approach to manufacturing.
