LONGi Solar Technology(ロンジソーラーテクノロジー) Company Profile

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.

In 2025, the prestigious U.S. testing and certification organization RETC (Renewable Energy Test Center) announced the "2025 PV Module Index Report," awarding LONGi the "Overall Highest Achiever" title for the seventh consecutive year. This award is given only to companies that have achieved outstanding ratings in all three areas of reliability, performance, and manufacturing quality. RETC's tests are conducted under stringent standards that exceed IEC specifications and are applied to major module products worldwide. Of the products evaluated this year, only 13% met the standards, but LONGi excelled in each category. In reliability testing, it received high ratings for damp heat (DH), PID, temperature cycling (TC), and mechanical load (SDML). In performance testing, it recorded top-class results in LETID, LID, temperature coefficients, and PAN file performance. LONGi's seven consecutive awards demonstrate its leadership in product development, manufacturing, and quality control, reaffirming its role as a driving force in the high-quality development of the global solar industry.

LONGi has achieved the highest rating of AAA for 21 consecutive periods in the "PV ModuleTech Bankability Ratings" announced by the UK-based Informa, up to the first quarter of 2025. This is the longest record in the market and demonstrates the company's strong financial foundation, supply capacity, and research and development capabilities. In particular, it has set a world record for conversion efficiency with its heterojunction back contact (HIBC) technology and tandem solar cells, showcasing its leadership in technology. Products equipped with BC technology, such as Hi-MO X10 and Hi-MO 9, have secured large-scale projects worldwide, with cumulative shipments of BC modules exceeding 30 GW. The company will continue to contribute to the realization of a sustainable energy society.
