## Summary

Horay Solar is a Chinese photovoltaic module manufacturer headquartered in Wuxi, Jiangsu Province, founded in 2010. The company operates production facilities in China and Malaysia and maintains regional offices in Germany, the United States, and Kenya, giving it one of the broader geographic footprints among mid-tier Chinese manufacturers. Its reported annual manufacturing capacity stands at approximately 2.5 GW. Critically for project finance purposes, Horay Solar achieved BloombergNEF Tier 1 status in Q1 2025 and retained that designation through Q1 2026, confirming that commercial banks have financed large-scale projects using its modules. MY Solar Technology Co., Ltd. - the core entity of MY Solar Group - was also established in 2010 and is listed on the ENF Solar directory with an annual output of around 3 GW of solar modules, alongside inverters, energy storage batteries, and integrated power-plant systems. No publicly available confirmation of BloombergNEF Tier 1 status was found for MY Solar, which is a meaningful distinction for buyers whose projects require bankable equipment.

Horay Solar's product line centers on monocrystalline modules in 182 mm and 210 mm wafer formats, with a clear pivot toward N-type TOPCon technology and bifacial designs. Its high-wattage Galaxy series targets utility-scale and ground-mount applications - deployments of up to 15 MW using 665W Galaxy modules have been documented - while the Ocean series at around 440W is positioned for residential rooftop and commercial C&I use. Panel certifications include TUV, ETL, and ISO9001/14001/45001, with a 15-year product warranty and a 25-year linear power guarantee retaining at least 84.8% output. MY Solar's broader product ecosystem - covering modules, inverters, and storage - positions it more as a one-stop-shop for EPC contractors and system integrators than as a pure-play module specialist.

For most international buyers evaluating a bankable, mid-scale Chinese manufacturer, Horay Solar currently offers a clearer institutional track record thanks to its confirmed Tier 1 designation and established European presence. MY Solar is a credible alternative, particularly for integrators who value a bundled supply of modules and balance-of-system components from a single vendor. The two companies are close in age and headline capacity, so buyers working outside bank-financed structures may find them broadly interchangeable on price and specification - in which case local distributor warranty support and after-sales service should drive the final decision.
