LONGi has once again been recognized as a ‘Top Performer’ by Kiwa PVEL in its 2025 PV Module Reliability Scorecard, based on its modules’ excellent results in testing. This year marks the eighth time LONGi has received this PVEL recognition, consolidating its sustained leadership in global PV module reliability and performance.
Since its launch in 2012, Kiwa PVEL’s Product Qualification Program (PQP) has systematically evaluated the long-term reliability and performance of PV modules through rigorous testing protocols that far exceed IEC standards. The PQP adheres to four core principles: Evidence-based data, standardized processes and third-party witnessed sampling to prevent “golden samples”, continuous updates to test standards ensuring alignment with the latest PV module technologies.
In the latest scorecard, LONGi secured “Top Performer” designation due to its outstanding results in critical tests including TC (Thermal Cycling), MSS (Mechanical Stress Sequence), PID (Potential Induced Degradation), LID+LETID (Light Induced Degradation and Light and Elevated Temperature Induced Degradation) and PAN File (Simulation Data File Performance).
