TONGWEI has once again demonstrated its commitment to module reliability by being named a “Top Performer” in Kiwa PVEL's 2026 PV Module Reliability Scorecard. This marks the third consecutive year that TONGWEI has received this prestigious recognition, highlighting the outstanding reliability and long-term performance of its photovoltaic modules.
As one of the industry's most trusted independent reliability assessments, Kiwa PVEL's PV Module Reliability Scorecard evaluates manufacturers through rigorous accelerated stress testing protocols that exceed conventional IEC certification standards. The results have become an important reference for global investors, developers, and EPC companies when selecting PV products for long-term projects.
In the latest 2026 Scorecard, only 15 manufacturers worldwide achieved top-tier performance across 7–8 reliability test categories, with TONGWEI among this leading group. Notably, the 2026 testing program introduced the new UVID120 (Ultraviolet-Induced Degradation 120 kWh) test. TONGWEI's TNC modules achieved outstanding results across seven key reliability assessments, including UVID120, TC600 (thermal) cycling), DH 2000 (damp heat), PID 192 (potential-induced degradation), combined LID+LeTID, MSS (mechanical stress sequence), and PAN energy yield performance tests, demonstrating exceptional durability and stability under diverse environmental conditions.
These results further validate the long-term reliability of TONGWEI's TNC module series, which is designed to deliver consistent energy generation even in challenging climates and complex application scenarios.
Building upon its proven reliability advantages, TONGWEI continues to advance photovoltaic technology through continuous innovation. The latest TNC 3.0 module series integrates advanced technologies to achieve higher power output, improved efficiency, and enhanced energy yield. With a maximum power output of 770W and module efficiency of up to 24.8%, TNC 3.0 provides customers with high-performance solutions to maximize project returns.
From rigorous reliability testing to next-generation product innovation, TONGWEI remains committed to delivering high-quality, durable, and efficient PV solutions that support the global transition toward sustainable energy.
