DAH Solar vs Horay Solar - solar panel manufacturer comparison

DAH Solar and Horay Solar are both Chinese photovoltaic module manufacturers holding Tier 1 BNEF status as of Q1 2025, but they differ considerably in scale, market reach, and portfolio depth. DAH Solar, founded in 2009 in Hefei, has grown into a significant global player with a production capacity of 10 GW and a workforce exceeding 2,000 employees. Its modules reach over 120 countries, with Europe and Latin America as primary export destinations, backed by a European warehouse in Rotterdam and a regional office in Frankfurt, with documented market activity in Germany, Austria, Italy, and Poland. Horay Solar, founded a year later in 2010 in Wuxi, Jiangsu Province, operates at a smaller scale with a 2.5 GW production capacity and approximately 400 employees. The company has established a European foothold in Valencia, Spain, targeting the European market as a key growth region.

Both manufacturers have adopted TOPCon as their leading cell technology, though DAH Solar has integrated it across a larger share of its portfolio - 79.6% of 363 listed models - compared to Horay Solar's 56% of 182 models. DAH Solar's distinctive Full-Screen frameless module design has attracted positive attention in independent testing, with TüV Nord field tests confirming higher energy yields versus conventional framed modules. Its portfolio reaches up to 725 Wp with an 87% bifacial share, making it a natural fit for utility-scale ground-mount and commercial C&I projects where bifacial gain and high wattage are priorities. Horay Solar, meanwhile, delivers a slightly higher average module efficiency of 22.46% versus 22.10%, and a meaningfully better average temperature coefficient of -0.28%/°C versus -0.299%/°C, which translates to lower power losses on hot days - an advantage for residential rooftop installs in warmer climates and for C&I projects across southern Europe. Horay Solar also offers a marginally longer average product warranty of 30 years compared to DAH Solar's 29.4 years.

For international buyers choosing between the two, DAH Solar presents a lower-risk proposition for large-scale procurement, given its greater manufacturing capacity, established European logistics infrastructure, broader and more bifacial-heavy product range, and longer global track record. Horay Solar is a credible alternative for buyers prioritizing average efficiency and thermal performance in residential or smaller commercial projects, though its narrower geographic footprint and smaller organizational scale warrant closer due diligence on after-sales support. Both carry Tier 1 bankability supporting project financing, but DAH Solar's capacity advantage and brand visibility currently give it an edge in competitive tenders.
