nadinebuetow@longi.comLONGi has maintained its Tier 1 status in the BloombergNEF (BNEF) PV Module Maker Tier 1 List for the fourth quarter of 2025. The classification is based on the latest BloombergNEF assessment released on December 16, 2025.
The BloombergNEF Tier 1 classification is widely used by banks, investors, and project developers as a reference for assessing the bankability of photovoltaic module manufacturers. It is based on non-recourse project financing data and reflects manufacturers whose modules have been deployed in projects that successfully reached financial close under lender due diligence processes.
In non-recourse project financing, lenders are repaid from the cash flows generated by the project itself, without access to the wider assets of the project sponsor. This financing structure places strong emphasis on predictable energy generation, operational reliability, and long-term technology performance, making component selection a critical part of the bankability assessment.
Tier 1 classification reflects increasing use of back contact technology in non-recourse financed solar projects
BloombergNEF’s Tier 1 assessment is grounded in the financing decisions of commercial banks and financial institutions. Inclusion in the list indicates that a manufacturer’s modules have been accepted in non-recourse financed photovoltaic projects, where technology selection is subject to detailed evaluation of performance reliability, operational risk, and long term economic viability.
LONGi’s continued Tier 1 classification for Q4 2025 reflects the deployment of its photovoltaic modules in such bank financed projects during the assessment period. As back contact technology forms the core architecture of LONGi’s module portfolio, the Tier 1 status signals that projects using back contact technology have met the technical and financial criteria applied by lenders in real world financing scenarios.
In the context of non-recourse project finance, technology acceptance is driven by predictable energy yield, stable long-term performance, and risk profiles that are compatible with conservative financing structures. The use of back contact technology in bank financed projects indicates its growing acceptance across utility scale and commercial applications, where financing decisions are closely tied to technical bankability rather than short term cost considerations.
Back contact technology deployed at scale across utility and C&I projects in 2025
In 2025, LONGi recorded a series of significant milestones for its back contact (BC) technology across both utility-scale and commercial and industrial (C&I) segments. In Southern Europe, LONGi announced a landmark 225.9 MW Hi-MO 9 utility project agreement in Greece, marking the largest deployment of BC technology in Europe to date with modules delivering up to 660 W and an efficiency of 24.43 percent. The company also supported the United Kingdom’s inaugural back contact deployment in partnership with Cero Generation, supplying Hi-MO 9 modules for the 59 MW solar component of the Bramley project, a 115 MW co-located solar and battery energy storage system.
On the distributed generation front, LONGi’s Hi-MO X10 back contact module received industry recognition throughout the year. The Hi-MO X10 was awarded the pv magazine Award 2025 in the “Modules” category, with the jury highlighting its advanced HPBC 2.0 back contact bifacial performance and innovation that overcame long-standing limitations for back contact designs. Earlier in the year, the same module was among the winners of the Smarter E AWARD 2025 in the Photovoltaics category for its technological contribution, with the jury noting features including its zero-busbar structure and shading optimizer technology that enhances performance and reliability.
In addition, TÜV Rheinland recognized LONGi’s back contact product portfolio at the All Quality Matters Solar & ESS Congress, awarding the Hi-MO X10 Lightweight Module with the Lightweight PV Module Excellence Award and the Hi-MO 9 with the Ultra Quality PV Module Top Award following independent quality and performance evaluations.
The achievements in 2025 reflect continued technological progress and broader adoption of back contact solutions in both large-scale and commercial rooftop applications, supported by independent validation and industry accolades.
