## Summary

Hanersun is a Chinese solar module manufacturer headquartered in Nanjing, founded in 2015. The company has scaled consistently and by the end of 2025 had cumulatively shipped over 16 GW of modules, with annual production capacity estimated at around 5 GW. In Q4 2024 Hanersun made its debut on the PV Tech ModuleTech Bankability Report with a CCC+ rating and is listed as a Tier 1 manufacturer by BloombergNEF. Trina Solar, by contrast, was founded in 1997 by Jifan Gao in Changzhou, Jiangsu Province, and has grown into one of the world's largest module suppliers, with nameplate production capacity reported at approximately 100 GW by 2025. Trina holds long-standing consecutive BloombergNEF Tier 1 recognition for both PV modules and energy storage, ships to over 100 countries, and maintains regional headquarters across four continents. On institutional footprint - breadth of lender acceptance, global distribution depth, and years of documented bankability - Trina Solar carries considerably greater weight.

Hanersun's current portfolio centres on n-type cells across two technologies: TOPCon and HJT (heterojunction). The company was among the earlier producers to commercialise modules above 600 W and 700 W using large-format 210 mm wafers, and its bifacial TOPCon panels are positioned for residential rooftop, commercial and industrial (C&I), and utility-scale ground-mount applications. Trina Solar's flagship Vertex series is built around n-type i-TOPCon technology with the same 210 mm wafer standard: the Vertex S+ targets residential rooftops where compact form factors are important, while larger Vertex formats serve utility and commercial projects seeking maximum power output per panel. Trina Storage, the company's battery arm, has earned six consecutive BloombergNEF Tier 1 storage rankings, making Trina one of very few suppliers able to offer matched module and storage solutions at industrial scale.

For most buyers - particularly those financing larger commercial or utility projects where lender acceptance and long-term warranty backstop are critical - Trina Solar is the lower-risk default choice. Its decades-long bankability record, shipped volume, and global service infrastructure meaningfully reduce project financing risk. Hanersun is a credible alternative for buyers comfortable working with a younger, smaller supplier; its entry into the PV Tech bankability rankings and its dual TOPCon and HJT portfolio demonstrate a genuine development trajectory. For straightforward residential installations or price-sensitive C&I projects the two brands are broadly interchangeable on panel performance alone - the differentiating factor is institutional confidence and supply-chain resilience, where Trina Solar retains a clear and meaningful edge.
