[Trina Solar] Latest TOPCon Solar Module Vertex N G3 to Make Asia Debut at PV EXPO 2026

　Trina Solar (Trina Solar Co., Ltd., SH:688599; hereinafter "Trina Solar"), a global leader in solar power and energy storage solutions, held the first public unveiling in Asia of its N-type TOPCon Ultra-cell technology, "Vertex N G3" (hereinafter Vertex N G3), at PV EXPO 2026, which was held at Tokyo Big Sight until Thursday, March 19.

Vertex N G3 is designed for utility-scale solar power generation, achieving a maximum output of 760W while combining improved power generation efficiency at the system level with long-term reliability.

　Trina Solar is a global manufacturer of solar power modules with cumulative global shipments exceeding 292 GW as of the end of June 2025. It has been selected as a PVEL Top Performer—a key indicator of reliability recognized by EPC procurement teams worldwide—for 11 consecutive years. Additionally, in September 2025, it was named to S&P Global Commodity Insights' first "Tier 1 Cleantech Company" list in the solar module sector.

This certification evaluates companies based on six indicators: market presence, scale, global diversity, financial performance, and corporate sustainability, indicating a low-risk procurement source for lending institutions, developers, and power purchasers. Unlike overseas manufacturers without a local presence, Trina Solar's domestic team in Japan provides support for project development, technical consulting, and after-sales coordination.

　Vertex N G3 (NEG21C.20Q) is based on the N-type i-TOPCon technology that Trina Solar has been researching and developing since 2015. Improvements in cell design, such as multi-cut cell technology, ultra-fine busbar electrode formation technology, and high-density interconnection technology, reduce energy loss during the conversion of sunlight into electrical energy. This has resulted in a maximum output of 760W and a module conversion efficiency of 24.5%.

Furthermore, the low-voltage design increases string output, reducing BOS (Balance of System) and LCOE (Levelized Cost of Energy) by approximately 2–3% compared to standard modules. These features are particularly effective for utility-scale solar power projects in Japan, where installation footprint and cost efficiency are prioritized.

　For commercial and industrial (C&I) rooftop installations, the company offers the Vertex S+ G3 (NEG9RP.28Z). Achieving a maximum output of 485W with a lightweight design of 1762 x 1134 x 30 mm, this module is suitable for installation on Japanese commercial rooftops where space is limited.
