Written summary
Horay Solar Co., Ltd. is a Chinese photovoltaic manufacturer established in 2010 and headquartered in Wuxi, Jiangsu Province. The company reports an annual module production capacity of approximately 2.5 GW and has achieved confirmed BloombergNEF Tier 1 status, appearing on the list as recently as Q1 2025 and Q1 2026. Tier 1 recognition means Horay Solar's modules have been used in projects financed on a non-recourse basis by multiple independent commercial banks, giving the brand meaningful institutional credibility with lenders and project developers. Gamko New Energy, by contrast, is a younger manufacturer based in Nantong, Jiangsu, operating since approximately 2017. Its reported annual production capacity stood at around 1.2 GW in 2023, and no independent confirmation of BloombergNEF Tier 1 status was found in available sources, which limits its bankability profile for financed projects.
Horay Solar's product portfolio centres on advanced cell architectures - TOPCon N-type, HJT, and back-contact variants have all been confirmed in published product lines. The flagship Ocean series is an N-type bifacial module aimed primarily at commercial and industrial rooftop and ground-mount applications, where the elimination of light-induced degradation and improved low-light yield justify the premium positioning. Third-party certifications include TUV Rheinland, Lloyd's, and Inmetro. Gamko New Energy covers a broader power range, from small off-grid panels up to modules exceeding 500 W, using confirmed TOPCon and PERC technologies in both monofacial and bifacial configurations. The company holds IEC 61215, IEC 61730, and CE certifications enabling European market access, and declares a 30-year product warranty - though prospective buyers should verify current warranty terms directly with the manufacturer.
For most international buyers - particularly those seeking project finance or entering regulated European markets - Horay Solar is the more defensible choice, given its verified Tier 1 bankability and broader technology portfolio. Gamko New Energy may suit price-sensitive or smaller-scale procurement, but buyers should conduct thorough due diligence before committing at scale, as its institutional track record is less independently verified.
