AE Solar vs Huasun - solar panel manufacturer comparison

AE Solar was founded in 2003 and is headquartered in Königsbrunn, Germany, making it one of the most established European solar module manufacturers on the market today. The company holds BloombergNEF Tier 1 bankable status and is recognised as Europe's sole Tier 1 manufacturer in that ranking, operating production facilities in China, Georgia, and Turkey with a combined capacity of approximately 2.5 GW - and an announced 10 GW expansion plant planned for Romania that would represent a major step toward EU-domestic manufacturing. Huasun, by contrast, was established in 2020 in Xuancheng, Anhui Province, China, and has scaled rapidly into the world's largest dedicated HJT module manufacturer, with a stated production capacity of 20 GW and over 11 GW shipped globally as of 2025. Listed on the Shenzhen Stock Exchange and employing more than 2,500 people, Huasun also holds Tier 1 bankable status and has claimed a record heterojunction cell efficiency of 26.5% in laboratory conditions, underlining its technology-forward positioning.

AE Solar's broad portfolio of 442 modules spans monofacial and bifacial designs, with TOPCon n-type technology representing roughly half the lineup. Peak module efficiency reaches 24.43% with a portfolio average of 21.3%, and the wide product range - covering varying form factors and power classes - makes AE Solar well suited for residential rooftop installs, commercial C&I projects, and mid-scale ground-mount arrays where European quality assurance, a DIBt certification, and a near 30-year average warranty carry weight with financiers and end customers alike. Huasun's more focused portfolio of 126 modules leans heavily on HJT technology (approximately 75% of the lineup), delivering an average panel power of around 523 Wp, an average efficiency of 21.9%, and a temperature coefficient of -0.26%/°C - meaningfully better than AE Solar's -0.31%/°C. Combined with a bifacial ratio approaching 90%, these characteristics make Huasun modules particularly compelling for utility-scale ground-mount projects, agri-PV installations, and vertical bifacial applications where rear-side yield and thermal performance directly affect project economics.

For international buyers choosing between the two, the decision hinges on project scale and supply chain priorities. AE Solar's two-decade track record, European operational footprint, and planned Romanian gigafactory offer supply chain resilience within the EU - advantages that matter in residential, C&I, and regulated procurement contexts. Huasun delivers a technically differentiated HJT product with superior temperature performance and near-total bifaciality, advantages most impactful in large, performance-driven ground-mount projects where even marginal efficiency and bifaciality gains compound over a 25-30 year asset life. Buyers prioritising cell-technology leadership and maximum energy yield will favour Huasun; those seeking a European-anchored supplier with a mature installer network and a wider product selection are better served by AE Solar.
