Recently, PV Tech, the authoritative analyst in the PV industry, released the Q1 2026 PV ModuleTech Bankability Report for module manufacturers. LONGi has maintained the highest AAA rating for the 25th consecutive time.
The PV ModuleTech bankability ratings are derived from a thorough evaluation process that examines manufacturers across several critical dimensions, including value chain strength, production capacity, global shipment profiles, capital expenditure (capex), R&D investment and cash-flow management.
LONGi’s consistent AAA status reflects not only its robust operational metrics but also its dedication to advancing solar technology.
Technological Innovation: BC Evolution Never Ends
As a leader in BC technology and invest the most in BC R&D, LONGi has been continuously advancing on the path of BC.
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 (NREL) to exceed 26.4% efficiency, also setting a new 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%.
Scenario Differentiation: A New Chapter of Energy Storage
At the technical application end, LONGi’s product matrix is becoming increasingly tailored to scenario-based demands.
On March 9, at the Jinan International PV and Energy Storage Application Conference, LONGi launched the Hi‑MO X10 special fire‑resistant module and LONGi Hi ROOF E system, addressing PV fire risks at the source and driving cost reduction for complex rooftops through rail‑free system innovation, shifting industry competition from price back to value.
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.
In BloombergNEF’s Q2 2026 Global Energy Storage System Manufacturer Tier 1 list, LONGi has been included for eight consecutive quarters, solidifying its position in the global energy storage first echelon.
From technological breakthroughs to product upgrades, LONGi is reshaping efficiency and safety standards in the PV‑storage industry through sustained innovation
LONGi’s consecutive 25 AAA ratings precisely prove that only enterprises that adhere to technological innovation and prioritize product quality can win long-term trust from the market.
In the accelerating global energy transition, a healthier and more resilient Chinese PV industry will not only navigate through cycles and achieve steady long-term development but also surely contribute more solidly to the global "carbon neutrality" goals.
