Recently, BloombergNEF (BNEF), a world-renowned authoritative research institution in the energy sector, successively released the Q1 2026 rankings of Global PV Module and Energy Storage System Manufacturer Tiering. Bolstered by its outstanding financial reliability and excellent global market performance, LONGi was once again named a Tier 1 PV module manufacturer and made its debut on the Tier 1 energy storage list. This dual recognition marks LONGi’s strategic upgrade from a global leader in photovoltaics to an integrated energy solution provider of "PV+Storage+Hydrogen Energy".
Dual Tier 1 Certifications: A Testament to Strength
BloombergNEF’s tiering system is renowned for its rigor and objectivity, serving as a critical reference for investment, financing and procurement in global new energy projects. Its core evaluation logic centers on robust finance—namely, whether an enterprise’s products can secure non-recourse debt financing from banks. It also explicitly requires manufacturers to own independent production facilities and conduct sales under their own brand names.
LONGi’s consistent presence on the PV Tier 1 list attests to the company’s strong global brand credibility and competitive advantages in the photovoltaic sector.
The BNEF Tier 1 selection criteria for the energy storage sector are equally stringent: the system rates hundreds of global stationary energy storage manufacturers with transparent tiering based on financability proven by project deployment. Brands on the list must possess independent manufacturing plants and have supplied batteries and energy storage systems for projects with a capacity of at least 10 MW or 10 MWh (whichever is higher) in the past two years.
LONGi’s successful debut on the list at its first attempt fully demonstrates the high starting point and strong market recognition of its energy storage business.
The "Stability Triangle" Empowering Transition
In November 2025, LONGi grandly launched its one-stop energy storage solutions in the UK. Dennis She, Vice President of LONGi, elaborated on the company’s energy storage strategy in detail and proposed an energy architecture of the "Stability Triangle" with photovoltaics, energy storage and hydrogen energy at its core.
"Photovoltaics is the creator of clean energy, energy storage acts as the stabilizer of power systems, and hydrogen energy is the regulator for balancing energy systems," noted Dennis She. "The synergy of the three will build a truly accessible, highly resilient and affordable zero-carbon energy system."
At present, LONGi has accumulated leading technologies in photovoltaics and hydrogen energy—its HIBC solar cell has achieved a conversion efficiency of 27.81%, and the company ranks first in the world in ALK electrolyzer production capacity. The launch of its energy storage business further completes LONGi’s strategic layout of the entire industrial chain for "PV+Storage+ Hydrogen Energy ".
LONGi’s "PV+Storage+ Hydrogen Energy integration" strategy has yielded remarkable results in market expansion. Recently, at the Solar Solutions exhibition in Amsterdam, the Netherlands, LONGi entered into strategic cooperation with three core European partners, signing cumulative agreements for 600 MWh of energy storage systems and 100 MW of high-efficiency PV modules.
In addition, LONGi’s energy storage business has recently won multiple orders in the Chinese, Southeast Asian and other markets, with shipments and deliveries being carried out successively.
