Written summary
Horay Solar is a Chinese module manufacturer founded in 2010, successor to the My Solar brand, headquartered and manufacturing in Wuxi, Jiangsu province. It holds confirmed BloombergNEF Tier 1 status, including the Q1 2026 list, which supports project financing eligibility, and runs automated production lines with roughly 2.5 GW of annual capacity. Resun Solar was established in 2007, also in China, and operates at a smaller scale, with production capacity generally cited around 1 GW across two ISO 9001 and 14001 certified factories. Resun does not consistently appear on current Tier 1 rankings in available sources, so on institutional footprint and production scale, Horay Solar currently has the stronger standing.
Both brands serve a similar spread of use cases, spanning residential rooftop systems, commercial and industrial installations, and utility-scale ground-mount projects, making either a reasonable fit for international buyers sourcing across market segments. Horay Solar's lineup includes 182mm and 210mm formats in mono and bifacial configurations, built on TOPCon, HJT and BC cell technologies, with inverters and storage systems rounding out its offering. Resun Solar focuses primarily on TOPCon modules ranging from 420 W to 590 W and brings over 15 years of experience as a solar home system supplier for World Bank-backed projects, giving it a track record across varied climates and grid conditions, alongside TUV, CEC and PID-free certifications and CHUBB insurance coverage.
For a buyer prioritizing straightforward bankability on larger financed projects, Horay Solar is the safer default given its confirmed Tier 1 status and larger production base. Resun Solar remains a credible option, particularly for smaller residential or development-focused projects where its World Bank supply history is relevant, but buyers should verify the current Tier 1 status of the specific batch through their distributor before committing to large-scale financed installations.
