LONGi Green Energy Technology has secured the top position in Wood Mackenzie’s 2026 Global Solar PV Module Manufacturer Ranking, based on 2025 operational data, while also earning the highest Grade A rating in the consultancy’s Supplier Qualification Program.
Wood Mackenzie, a leading global energy research and advisory firm, evaluated 48 manufacturers across 10 countries using a framework that covers capacity utilisation, technology maturity, financial strength, supply chain resilience, ESG performance, reliability standards and research and development investment. The assessment is widely used by investors, developers and financial institutions as a benchmark for procurement and financing decisions.
The Grade A rating is the highest level in Wood Mackenzie’s supplier qualification system and indicates that a manufacturer meets stringent benchmarks associated with best practice across the global solar supply chain. According to the methodology, companies achieving this rating are considered low risk and highly reliable long term partners for utility scale projects and institutional investors.

Wood Mackenzie noted that Chinese manufacturers continue to dominate the global solar supply chain, with nine of the top ten ranked companies headquartered in China. Yana Hryshko, Head of Solar Supply Chain Research at Wood Mackenzie, said Chinese firms remain global leaders in manufacturing scale, technology advancement and operational efficiency.
LONGi’s top ranking reflects its sustained investment in research and development and large scale manufacturing capability. The company reported major advances in back contact technology, including its independently developed HIBC solar cell, which achieved a certified conversion efficiency of 28.13% for crystalline silicon cells according to Germany’s Institute for Solar Energy Research Hamelin. In addition, LONGi’s EcoLife series, based on HIBC technology, reached a mass production module efficiency of 25% in the April 2026 TaiyangNews commercial module efficiency rankings.
The company has also expanded its product portfolio around BC technology to address multiple deployment scenarios. These include modules designed for anti dust, anti glare, lightweight applications and fire resistant environments, as well as specialised solutions for harsh conditions such as sandy terrain, barren land, offshore installations and hail prone regions.
Hi MO 9 Ice Shield module 
In parallel, LONGi has been advancing high durability utility scale products. The Hi MO 9 Ice Shield module has been named a finalist for The smarter E AWARD 2026 in the photovoltaic category. The module is designed for extreme weather environments and has been tested against hailstones up to 55 mm in diameter at high impact speeds when installed at a 30 degree inclination.
The company reports that this hail resistance level covers around 97% of recorded hail events based on meteorological and asset risk data. The module features a dual glass structure with reinforced framing and supports mechanical loads of up to 5,400 Pa.
Built on HPBC 2.0 back contact technology, the Hi MO 9 Ice Shield delivers output power of up to 670 W with efficiency reaching 24.8%. It also features a 30 year power warranty, with first year degradation below 1% and annual degradation of 0.35% from year two onwards.
LONGi stated that the product is already commercially available and expands its Hi MO 9 portfolio, reinforcing its strategy of combining high efficiency with enhanced resilience for utility scale solar projects.
