LONGi Solar Technology(ロンジソーラーテクノロジー)

In June 2025, LONGi was recognized as a "Top Performer" for the eighth consecutive year in the "2025 PV Module Reliability Scorecard" announced by KiwaPVEL. KiwaPVEL is a globally recognized independent testing organization, and this certification demonstrates the highest standards of product reliability and performance in the industry. This time, LONGi achieved excellent results in all tests, including Temperature Cycle Test (TC), Dynamic Mechanical Load (MSS), PID Test, Light-Induced Degradation and High-Temperature Induced Degradation Tests (LID + LETID), and PAN file performance evaluation. Notably, in 2025, only 21 products worldwide were selected as "Top Performers" across all tests, and only 3 products were chosen for PAN performance, with LONGi being one of them. This achievement reflects LONGi's continuous improvement in technological innovation and manufacturing quality, and it is a testament to its commitment to providing more stable, high-efficiency, and sustainable solar solutions to customers around the world.
