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

In the "PV ModuleTech Bankability Report" released by the authoritative organization in the PV industry, PV Tech, LONGi has achieved the highest rank of AAA for the 23rd consecutive time. The rating is a comprehensive evaluation of factors such as supply chain strength, production capacity, shipment performance, R&D investment, and cash flow management. LONGi's continued AAA rating demonstrates its solid management and firm commitment to technological innovation. Faced with "excessive competition" in the industry, LONGi has differentiated itself with its BC (Back Contact) technology. The HPBC 2.0 module has achieved a mass production efficiency of 24.8% and a yield of over 97%, while the HIBC has reached 25.9% and over 700W. From January to September 2025, cumulative sales of BC modules reached 14.48GW, confirming that technological innovation supports healthy growth. LONGi believes that "technology and quality are the keys to gaining market trust" and contributes to the global energy transition. The Chinese PV industry has significantly reduced power generation costs over the past decade, leading the green transition.

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.
