## Summary

Horay Solar is a Chinese manufacturer founded in 2010 and headquartered in Wuxi, Jiangsu Province, operating as the successor brand to My Solar. The company holds confirmed BNEF Tier 1 bankability status as of Q1 2025 and reports an annual production capacity of approximately 2.5 GW, with certifications including TUV, IEC, and CE supporting its position in European procurement. JS Solar - formally Yixing JS Solar Co., Ltd. - is also based in the greater Wuxi metropolitan area (Yixing city), with roots in the solar market dating to 2004 and a dedicated production base established in 2007. JS Solar claims a substantially larger production footprint, reportedly reaching 20 GW of annual capacity, though independent confirmation of BNEF Tier 1 status for JS Solar was not found in publicly available sources as of mid-2025. On the basis of verified bankability, Horay Solar carries the stronger institutional footprint for project finance and lender-approval contexts.

Horay Solar's catalogue centres on N-type TOPCon modules in 182 mm and 210 mm cell formats, available in both mono-facial and bifacial configurations, with products suited to residential rooftop, commercial and industrial (C&I), and utility-scale ground-mount installations. JS Solar offers a considerably broader portfolio - reportedly around 137 distinct panel models spanning outputs from 200 W to 670 W - with PERC as the dominant cell technology and a smaller share of TOPCon modules. This gives JS Solar an advantage in range and pricing flexibility across varied project sizes, while Horay Solar's tighter, TOPCon-focused lineup appeals to buyers prioritising current-generation cell efficiency.

For institutional buyers where bankability is a contractual requirement - utility developers, infrastructure funds, or EPC contractors operating under lender technical due diligence - Horay Solar's confirmed Tier 1 status makes it the lower-risk default. JS Solar's scale and catalogue breadth suit volume distributors and installers who need pricing leverage and a wide selection of wattages. For standard residential or C&I projects where Tier 1 status is not a formal contract condition, the two brands are broadly interchangeable, and the decision will likely come down to distributor availability and per-watt cost at the time of purchase.
