Sungrow vs Trina Solar - solar panel manufacturer comparison

Sungrow was founded in 1997 in Hefei, Anhui Province, China, and has grown into the world's leading manufacturer of PV inverters, holding an estimated 23-25 percent share of the global inverter market as of 2025. The company entered the solar module segment more recently, launching its own N-Type TOPCon panel line in 2025. In BloombergNEF's 2025 Inverter Bankability Survey, Sungrow secured the top position for the sixth time with 100 percent recognition among lenders, underscoring exceptional institutional confidence in its core product category. Trina Solar, also founded in 1997 and headquartered in Changzhou, Jiangsu Province, China, is by contrast a dedicated module manufacturer with annual production capacity reported at around 80-100 GW and cumulative global shipments exceeding 292 GW by mid-2025. Trina has achieved a 100 percent bankability rating in BloombergNEF's PV Module Bankability survey eight consecutive times. As a specialist panel manufacturer with deep lender relationships in the module segment, Trina Solar carries the stronger institutional footprint specifically for solar modules.

Sungrow's solar panel offering, still relatively new, centers on bifacial N-Type TOPCon modules designed to integrate seamlessly with the company's inverter and battery storage ecosystem, making them a natural fit for installers building full Sungrow systems across residential, commercial, and industrial rooftop applications. Trina Solar operates across all major market segments through well-established product families. The Vertex S and Vertex S+ series address residential and light commercial rooftop projects using both PERC and i-TOPCon cell technology, with the latest Vertex S+ G3 generation reaching up to 24.3 percent module efficiency. For utility-scale ground-mount and large commercial projects, the Vertex N series offers outputs up to 760 W at 24.5 percent efficiency, as confirmed by pv-magazine coverage of the module's December 2024 launch.

For buyers purchasing solar modules as a standalone product, Trina Solar is the more straightforward default choice: it brings decades of dedicated manufacturing experience, a global service network, and unambiguous bankability credentials specifically in the module category. Sungrow panels make the most sense for installers already committed to the Sungrow inverter and storage ecosystem, where tighter integration can offset the shorter module track record. For institutional or utility-scale projects where lender due diligence scrutinizes module manufacturer history closely, Trina's eight consecutive 100 percent bankability ratings give it a clear and well-documented advantage.
