AE Solar vs Horay Solar - solar panel manufacturer comparison

AE Solar, founded in 2003 and headquartered in Königsbrunn, Germany, is one of Europe's most established solar module manufacturers, with over two decades of market presence, a production capacity exceeding 2 GW, and a catalog spanning 442 panel variants. Horay Solar, established in 2010 in Wuxi, China, has scaled rapidly to a 2.5 GW annual production capacity with a focused portfolio of 182 models. Both manufacturers hold Tier 1 status per BloombergNEF - AE Solar on the basis of its longstanding European brand recognition and Horay Solar confirmed as recently as Q1 2025 - making both viable for financed and utility-scale projects. AE Solar operates across more than 100 countries and received the Kiwa PVEL Top Performer Award in 2025, while Horay Solar supports its international reach through warehouses and operations centers in Europe and North America.

Both manufacturers have embraced TOPCon as their leading cell technology, which accounts for 49.8% of AE Solar's lineup and 56% of Horay Solar's portfolio. AE Solar reaches a higher peak power output at 730 Wp and a maximum module efficiency of 24.43%, giving it an edge in space-constrained residential rooftop installations and premium commercial C&I projects where individual panel performance is paramount. Horay Solar, however, leads on average module efficiency across its catalog (22.46% versus 21.34%) and posts a meaningfully better average temperature coefficient of -0.28%/°C compared to -0.31%/°C for AE Solar - an advantage that compounds over time in warm climates and large-scale ground-mount installations. Horay Solar also carries a higher share of bifacial modules (67% versus 64%) and offers a uniform 30-year power warranty across its portfolio, versus AE Solar's catalog average of approximately 29.7 years.

For international buyers choosing between the two, AE Solar is the stronger fit for residential and commercial rooftop projects where European brand pedigree, a broad model range, and independently validated quality matter to end customers. Horay Solar is the more compelling option for utility-scale and ground-mount developers who prioritize superior average efficiency, a better temperature coefficient, and consistent long-term warranty terms - all of which support favorable yield projections and lender confidence in large financed portfolios.
