## Summary

Resun Solar is a Chinese module manufacturer headquartered in Suzhou, founded around 2005-2007, with more than 15 years in the market and past experience as a qualified supplier for World Bank solar home system projects. It operates roughly 1 GW of annual production capacity, sells into over 80 countries, and holds standard certifications such as TUV, IEC61215 and IEC61730, though available sources do not clearly confirm current BloombergNEF Tier 1 status. Sunpro Power, founded in 2018 and based in Yuhuan with a second production site in Wuxi, is a younger but faster-scaling brand that has held BNEF Tier 1 status continuously since Q2 2022, with capacity now above 2 GW annually and expansion toward 3.5-4 GW underway. On institutional footprint and documented bankability, Sunpro Power currently has the stronger position.

Resun Solar's catalog spans polycrystalline and monocrystalline panels from about 420W to 590W, including bifacial modules, aimed at residential rooftops as well as larger commercial and MW-scale projects. Sunpro Power is built around TOPCon cell technology, supplemented by HJT and back-contact modules, covering a wider 375-720W range, which positions it more toward buyers seeking newer n-type technology for both rooftop and utility-scale ground-mount installations. Both brands carry standard industry certifications (TÜV, UL, CE), though Resun stands out with a notably long 30-year performance warranty compared to Sunpro's more typical 25-year term.

For a typical international buyer, particularly an EPC contractor or investor who needs BNEF-verified bankability, Sunpro Power is the safer default choice given its newer TOPCon technology and consistently documented Tier 1 status. Resun Solar remains a reasonable budget-oriented option with a long market history, but its institutional standing is less clearly documented - for standard rooftop installations, the two brands can largely be treated as interchangeable.
