The results are in, and both PVEL''s PV Module Reliability Scorecard and RETC''s PV Module Index (PVMI) awarded LONGi with Top Performer status for its Hi-MO 4 and Hi-MO 5
Its next-generation HPBC 2.0 modules — Hi-MO 9 and Hi-MO X10 —have passed the stringent PID-p (Potential Induced Degradation – Polarization) testing. The tests were conducted
2.2. Scoring methodology For every product, 5 samples have been shipped to Gsola''s lab to conduct the tests and inspections according to the above flowchart.
China''s solar giant LONGi has been awarded "2022 Top Performer" in the annual PV Evolution Labs (PVEL) PV Module Reliability Scorecard. It is the sixth consecutive year the company has been
LONGi''s HPBC 2.0 based modules, Hi-MO 9 and Hi-MO X10, have passed TÜV SÜD''s PID-p (Potential Induced Degradation-Polarization) testing in accordance with PPP 58234A:2025
China-based LONGi has become the first company to receive TÜV SÜD''s PID-p certification for its Hi-MO 9 and Hi-MO X10 HPBC 2.0 modules, confirming superior anti-degradation
LONGi''s modules demonstrated outstanding resistance to PID-p in rigorous tests simulating real-world conditions, confirming their superior efficiency and durability.
LONGi''s modules excelled in critical tests such as Thermal Cycling (TC), Mechanical Stress Sequence (MSS), and Potential Induced Degradation (PID). These tests simulate the harsh
LONGi''s HPBC 2.0 modules, Hi-MO 9 and Hi-MO X10, have successfully passed TÜV SÜD''s PID-p (Potential Induced Degradation-Polarization) testing in accordance with PPP
Only the most resilient and reliable products earn the “ Top Performer ” designation. In 2025, only 21 module types worldwide passed every PQP stress test. Of these, just three—including
