## Summary

Horay Solar is a Chinese photovoltaic module manufacturer headquartered in Wuxi, Jiangsu Province, founded in 2010. The company holds confirmed BloombergNEF Tier 1 status, maintained through at least Q1 2026, which certifies its bankability for projects backed by commercial lenders. Its annual module production capacity stands at approximately 2.5 GW, with supply reaching Europe, North America, Southeast Asia, and Latin America. Techwise Solar Technology Co., Ltd. - also known by its Chinese brand 绿鼎光伏 - is a fellow Chinese manufacturer with a declared annual production capacity of around 1 GW. While Techwise Solar markets its ODM/OEM capabilities as serving Tier 1 partners, no publicly available source confirms that Techwise Solar itself appears on the BloombergNEF Tier 1 list. On institutional footprint alone, Horay Solar holds a clear advantage.

Horay Solar's product range spans PERC, N-type TOPCon, and bifacial modules across 182 mm and 210 mm cell formats, covering residential rooftop, commercial and industrial, and utility-scale ground-mount segments - including high-wattage modules such as the Galaxy 665W series. The company holds TUV, ETL, ISO9001, ISO14001, ISO45001, and INMETRO certifications, supporting market entry in regulated jurisdictions. Techwise Solar similarly produces PERC, TOPCon, and bifacial glass panels across comparable cell sizes, but its commercial model appears oriented primarily toward OEM/ODM supply rather than branded end-market sales. Independent field reviews and third-party test data for Techwise Solar's branded modules are limited in publicly accessible sources.

For a typical international buyer - whether a residential installer or a project developer seeking bankable supply - Horay Solar is the more straightforward default, given its verified Tier 1 standing, broader distribution footprint, and documented project references. Techwise Solar may suit buyers specifically seeking OEM manufacturing capacity, but warrants closer due diligence on warranty terms, after-sales support infrastructure, and bankability acceptance by project financiers before commitment.
