SEG Solar Earns Wood Mackenzie Grade A Rating for Second Consecutive Time

SEG Solar ("SEG"), a leading U.S. solar module manufacturer, announced that it has earned the Grade A rating in Wood Mackenzie's 2026 Global Solar PV Module Manufacturer Ranking. Only 25 manufacturers worldwide received this designation. As one of the few U.S.-based companies on the list, SEG's consecutive appearance underscores its strength in manufacturing capability, financial health, and supply chain resilience.

Wood Mackenzie's ranking evaluated 48 module manufacturers across ten countries, covering 65% of global production capacity and 83% of global shipments. Suppliers are assessed across ten core criteria, including capacity utilisation, technology maturity, financial health, supply chain resilience, ESG performance, reliability standards, certifications, production experience, vertical integration, and R&D investment. To qualify for Grade A—the highest level in the Supplier Qualification Program—a manufacturer must meet at least five benchmark criteria. The framework has become a widely adopted independent standard among global project developers, investors, and financial institutions for evaluating module supplier bankability.

Manufacturing strength and supply chain integrity form the foundation of SEG's assessment. The company's second factory, a 4 GW facility in Tomball, Texas, will hold its grand opening on August 7, 2026. Building on this momentum, SEG has broken ground on a third factory totaling approximately 1.15 million square feet of manufacturing and warehouse space, expected to be completed by March 2027 and operational by May 2027. Upon commissioning, SEG's U.S. production capacity will reach 10.6 GW. The new facility will feature Heterojunction (HJT) production lines to address growing demand for high-efficiency modules.

SEG further strengthens its position through rigorous FEOC compliance across its material sourcing and production operations. In parallel, the company has launched ingot-wafer production facilities in Indonesia, securing upstream material supply and enhancing the resilience of its global supply chain against trade policy shifts—a level of vertical integration and geographic diversification that distinguishes SEG among U.S.-based manufacturers.

"Earning Grade A for the second consecutive time is an authoritative validation of SEG's competitiveness by international institutions," said Jim Wood, CEO of SEG Solar. "Backed by this independent endorsement, SEG delivers solutions that combine strong bankability with proven product reliability for regional procurement. We will continue to invest in R&D and capacity expansion, empowering global customers with increasingly efficient products."

With accelerating domestic capacity growth, advancing technology roadmaps, and a resilient global supply chain, SEG remains committed to strengthening its role as a trusted partner in the U.S. solar manufacturing ecosystem.
