## Summary

Haitai Solar is a Chinese manufacturer headquartered in Tangshan, Hebei Province, founded in 2006. The company earned BloombergNEF Tier 1 status in Q1 2025 and has maintained it since, operating across five production hubs in China with a total manufacturing capacity of approximately 10 GW. Trina Solar, founded in 1997 and based in Changzhou, Jiangsu Province, is one of the most established names in global solar - it has topped BNEF's bankability rating eight times and in 2025 achieved a 100% bankability score from all surveyed respondents, reflecting its sustained access to project finance across major markets. In terms of scale, institutional track record, and lender confidence, Trina Solar holds a substantially stronger position than Haitai Solar.

Haitai Solar's catalog spans modules from 310 W to 720 W, and the company is actively expanding into next-generation cell technologies - a 10 GW TOPCon cell factory is under construction in Anhui Province, and a 5 GW HJT project is in planning. Its portfolio addresses residential rooftop, commercial and industrial (C&I), and utility-scale ground-mount applications. Trina Solar has built its recent market leadership around the Vertex N i-TOPCon series, which became the first mass-produced module line to exceed 700 W back in 2023 and has since advanced to 760 W at a confirmed efficiency of 24.5%. The Vertex N family is structured across three tiers - approximately 495 W for residential, around 670 W for C&I, and 700 W and above for large-scale ground-mount - making it one of the most comprehensively tiered product lines in the industry.

For most international buyers, particularly those arranging non-recourse debt financing for utility-scale or large C&I projects, Trina Solar is the lower-risk default choice given its decades-long track record and best-in-class bankability ratings. Haitai Solar is a credible, BNEF-recognized alternative that may offer more competitive pricing for buyers less bound by lender requirements, though its shorter Tier 1 history means it carries modestly more institutional risk. In the residential rooftop segment the two brands are largely interchangeable, and local distributor availability together with price will typically be the deciding factors.
