Recently, PV Tech, a leading authoritative analysis institution in the photovoltaic industry, released its Q2 2026 Bankability Rating report. Leveraging its outstanding comprehensive strength, LONGi once again secured the highest AAA rating. To date, LONGi has held this distinction for 26 consecutive quarters, further cementing its leading position as one of the most trustworthy manufacturers in the global solar industry.
PV Tech's bankability rating is one of the most credible assessment benchmarks in the photovoltaic industry, subjecting companies to comprehensive and rigorous evaluations across multiple dimensions, including technological capability, manufacturing capacity, financial health, and market performance. The AAA rating signifies that a company meets the highest industry standards in product reliability, financial soundness, and long-term development potential. LONGi's achievement of this rating for 26 consecutive times fully underscores the strong recognition from the global market for its comprehensive strengths.
Behind this consecutive achievement of the highest rating lies LONGi's sustained breakthroughs in photovoltaic technology innovation. Recently, LONGi's independently developed HIBC solar cells were certified by Germany's Hamelin Institute for Solar Energy Research (ISFH) with a photoelectric conversion efficiency of 28.13%. The module efficiency based on HIBC cells has also reached a new high of 26.4%. Furthermore, as certified by the European Solar Test Installation (ESTI), LONGi's independently developed crystalline silicon‑perovskite tandem solar cells achieved a conversion efficiency of 35.5%, once again breaking the world record for perovskite tandem cell efficiency.
Beyond individual breakthroughs, LONGi is also building a systematic technological advantage. On July 14, at the 2026 Solar-Energy-Storage Innovation Technology Conference, LONGi officially introduced the concept of a 'Technology Forest,' showcasing eight foundational innovative technologies, including ACM technology, integrated conductive backsheet technology, shingling technology, and others. Supported by this deep technology matrix, LONGi continues to push the boundaries of industry efficiency and reliability.
The flourishing Technology Forest ultimately bears fruit in the marketplace. According to statistics, from 2023 through the end of 2026, LONGi's cumulative global shipments of BC modules are expected to approach 100 GW, with annual shipments showing leapfrog growth: from 6 GW in 2023, to 17 GW in 2024, to 23 GW in 2025, and an estimated over 50 GW in 2026. Designed for diverse application scenarios, BC modules now cover extreme environments such as severe cold and intense heat, and are capable of meeting various functional requirements including dust accumulation prevention, anti-glare, and special-grade fire protection."
In the field of solar-storage integration, LONGi has also achieved remarkable results. On April 1 of this year, LONGi officially released its 'Full-Stack LONGi · LONGi ONE' solar-storage integration strategy, leveraging full-stack self-developed native integration technologies to create the 'Solar Generator,' a benchmark for global efficiency and safety, fundamentally breaking the islanding effect of solar-storage systems from the source.
At the SNEC exhibition held in Shanghai this June, LONGi comprehensively showcased its full-scenario product matrix and series of solutions, including OneBank 2.0 and OneMatrix 2.0 for GWh-scale power stations, the commercial and industrial smart green power solution Hi‑MO ONE, the off‑grid and microgrid energy storage flagship OneNexus, as well as the full‑scenario collaborative converter core OneSync and the cloud‑based intelligent dispatch platform OneOS, achieving native integration from high‑efficiency BC photovoltaic technology to the full 5S energy storage system. The company plans to build 30 all‑capability local service centers in major global solar‑storage integrated markets by 2028.
From continuously topping the PV Tech AAA highest rating for 26 consecutive terms to the full implementation of its solar-storage integration strategy, LONGi is reshaping the industry's benchmarks for efficiency and safety through relentless innovation, contributing China's strength to the global energy transition. Looking ahead, LONGi will continue to focus on technological innovation and customer value, delivering more reliable and efficient products and solutions to serve its global partners.
