Written summary
Trina Solar is a Chinese manufacturer founded in 1997 and headquartered in Changzhou, China, with one of the most established institutional profiles in the global photovoltaic industry. The company has maintained continuous BloombergNEF Tier 1 status - reconfirmed in Q1 2025 - which reflects its consistent ability to supply bankable projects financed by independent commercial lenders. In 2024, Trina Solar ranked among the top three global module suppliers with approximately 77 GW shipped, and its nameplate production capacity stood at 95 GW in 2023, with a stated target of 120 GW by end of 2025. G-STAR, by contrast, is a Singapore-headquartered company founded in 2019, with manufacturing operations in the Philippines. Its first completed production phase covers 1 GW of module capacity and 1.5 GW of solar cells, with announced plans to scale total capacity to 17.5 GW. G-STAR does not appear on the BNEF Tier 1 list, which constrains its use in projects requiring bankable financing. On institutional credibility and demonstrated scale, Trina Solar has a commanding lead.
Trina Solar's commercial portfolio is built around n-type TOPCon technology under the Vertex brand. The Vertex S+ line - including the recently launched G3 generation with modules up to 485 W and confirmed conversion efficiency of 24.3% per pv magazine - targets residential rooftops and commercial and industrial (C&I) rooftop installations. For utility-scale ground-mount applications, Trina's larger 210 mm cell format modules, reaching outputs of 760 W as reported by pv magazine, are widely specified by project developers worldwide. G-STAR offers a broader technology mix, covering P-type, N-type, HJT, and Back Contact (BC) cell formats, with module outputs spanning 100 W to 740 W. Its products carry ETL, TUV, and California CEC certifications and include bifacial dual-glass options suited to residential, off-grid, marine, and RV applications.
For most international buyers - particularly those financing commercial or utility-scale projects through institutional lenders - Trina Solar is the more defensible default, backed by nearly three decades of shipment history, recurring Tier 1 recognition, and a clear technology roadmap anchored in TOPCon. G-STAR may suit buyers seeking a cost-competitive option for smaller or off-grid projects where bankability is not a hard contractual requirement, but its short market history and absence from BNEF rankings represent procurement risks that should be weighed carefully. The two brands are not interchangeable in contexts where lender or insurer acceptance of the module brand is a project condition.
