Horay Solar vs Trina Solar - solar panel manufacturer comparison

Horay Solar is a Chinese photovoltaic module manufacturer founded in 2010 and headquartered in Wuxi, Jiangsu Province. The company operates automated production lines with an annual output capacity of around 2.5 GW and entered the BloombergNEF Tier 1 list for the first time in Q1 2025 - a milestone that reflects its growing bankability and quality credentials, backed by certifications from TUV, IEC, CE, and CQC. Trina Solar, by contrast, is one of the world's largest PV manufacturers. Founded in 1997 by Jifan Gao in Changzhou, Jiangsu Province, Trina has been listed on Shanghai's STAR Market since 2020 and consistently ranks among the global top three module suppliers. The company shipped approximately 70-77 GW of modules in 2024, has surpassed 205 GW in cumulative deliveries, and maintains a presence in more than 100 countries. Trina Solar has held BNEF Tier 1 status for many years and earns a perfect rating in PVEL third-party module testing. On institutional footprint and global scale, Trina Solar holds a clear and substantial advantage.

Horay Solar's core product lineup centers on N-type TOPCon and PERC mono bifacial modules - notably the Ocean series with 182 mm and 210 mm cells - suited to residential rooftop installs as well as commercial and industrial (C&I) projects. The company operates a European after-sales service hub in Valencia to support regional customers. Trina Solar covers a considerably broader range: the Vertex S+ series (i-TOPCon technology, power outputs up to around 495 W, efficiency up to 24.3%) targets residential and C&I segments, while the high-wattage Vertex N series - exceeding 700 W - addresses large utility-scale ground-mount deployments. Both brands are available through European distribution channels, though Trina Solar benefits from a significantly wider installer network and deeper brand recognition across the continent.

For most international buyers - whether sourcing panels for residential rooftop projects or large commercial arrays - Trina Solar offers the stronger overall proposition: a well-documented reliability track record spanning nearly three decades, a 25-year product warranty with a guaranteed 89.4% performance retention at year 25, and broad distributor and financing support in virtually every major market. Horay Solar is a credible and emerging alternative, particularly for cost-aware buyers open to a smaller brand that recently achieved Tier 1 status and delivers competitive N-type TOPCon technology. In terms of cell technology the two brands are converging, but Trina Solar's scale and long-established bankability make it the lower-risk choice for buyers where project financing or insurance requirements demand a well-recognized name.
