PV Tech recently released the 2026 Q1 PV Module Manufacturer Bankability Ratings Report, awarding LONGi a AAA rating, the highest distinction in the industry. LONGi has now maintained this ranking for 25 consecutive quarters, reinforcing its position as one of the photovoltaic industry’s most established and trusted manufacturers globally.
The PV ModuleTech Bankability Ratings are widely regarded as one of the industry’s leading benchmarks for evaluating photovoltaic manufacturers, assessing factors including product reliability, financial strength, manufacturing capability, and long-term market competitiveness.
“Achieving an AAA rating for 25 consecutive quarters reflects LONGi’s long-term approach to technology development, manufacturing quality, and global market execution,” said Eric Luo. “As the energy industry continues to evolve, LONGi remains focused on advancing high-efficiency solar technology, strengthening product reliability, and delivering solutions that support the growing global demand for scalable, sustainable energy.”
Over the past year, LONGi has continued to advance across technological innovation, product performance, and global market expansion. This has earned the company international recognition that further demonstrates the company’s continued momentum within the renewable energy sector.
Technological Innovation
Recently, LONGi’s self‑developed HIBC solar cell has been certified by the Fraunhofer Institute for Solar Energy Systems ISE with a conversion efficiency of 28.13%, marking another breakthrough following the 28.04% efficiency recorded in January 2026, as it approaches the theoretical efficiency limit of crystalline silicon solar cells.
At the same time modules based on HIBC cells have been certified by the National Renewable Energy Laboratory to exceed 26.4% efficiency, also setting a record. Furthermore, in TaiyangNews’ April 2026 ranking of commercial module efficiencies, LONGi’s EcoLife series ranked first with a mass production module efficiency of 25%.
A New Chapter of Energy Storage
LONGi’s product matrix is becoming increasingly tailored to scenario-based demands.
In the solar-storage market, where a long-standing industry pain point has now been addressed by LONGi.
On April 1, LONGi officially unveiled its “Full‑Stack LONGi · LONGi ONE” PV‑storage integration strategy. Leveraging fully self‑developed native fusion technology, LONGi aims to build a “Sunshine Power Generator” that sets global benchmarks for efficiency and safety, eliminating the islanding effect in PV‑storage systems.
These achievements reflect LONGi’s long-standing commitment to innovation-driven growth, manufacturing excellence, and sustainable development, while continuing to push the boundaries of photovoltaic efficiency and commercial application.
Looking ahead, LONGi will continue accelerating the development and commercialization of advanced photovoltaic technologies, strengthening product competitiveness, and supporting the global transition toward a more resilient and sustainable energy future.
