## Summary

Horay Solar is a Chinese photovoltaic manufacturer headquartered in Wuxi, Jiangsu Province, with an annual production capacity of approximately 2.5 GW. The company earned Bloomberg New Energy Finance (BNEF) Tier 1 status for the first time in Q1 2025, a meaningful milestone that signals improving bankability and growing acceptance by project financiers. LONGi Solar, also headquartered in China - originally in Xi'an and founded in 2000 - operates at a categorically different scale, with back-contact (BC) module capacity targeted at around 70 GW by end of 2025 and long-term plans pointing toward 150 GW of annual module output. LONGi has maintained continuous BNEF Tier 1 status and, as of Q1 2026, holds a double Tier 1 recognition covering both PV modules and energy storage systems. On any measure of institutional footprint, LONGi is the substantially larger and more widely financed of the two.

Horay Solar's catalog addresses residential rooftop, commercial and industrial (C&I), and utility-scale ground-mount use cases. The company offers monofacial and bifacial configurations in 182 mm and 210 mm cell formats under the Solar Ocean and Solar Galaxy series, leveraging N-type TOPCon as its primary cell technology alongside legacy PERC lines. Modules carry TÜV, IEC, CE, and CQC certifications. LONGi, by contrast, has staked its product strategy on its proprietary HPBC (Hybrid Passivated Back Contact) technology, which powers the Hi-MO X6 and the flagship Hi-MO X10 - a module rated at up to 670 W and 24.8% module efficiency, outperforming conventional TOPCon by a notable margin according to the company. The Hi-MO range spans distributed generation and C&I segments as well as large utility projects.

For most international buyers - especially those arranging non-recourse project financing or requiring robust long-term warranty backing - LONGi is the safer default. Its scale, unbroken Tier 1 track record, and proprietary back-contact technology roadmap provide clearer risk mitigation for lenders and asset owners. Horay Solar is a credible consideration for smaller installers or developers seeking competitive module pricing from a newly Tier 1-certified supplier, but warranty depth and in-country service availability should be verified independently. The two brands are not interchangeable: the gap in manufacturing scale and institutional recognition is material.
