DAH Solar vs Talesun - solar panel manufacturer comparison

DAH Solar, founded in 2009 in China, has grown into a manufacturer with over 2,000 employees, a declared production capacity of 10 GW, and a distribution footprint spanning more than 120 countries. The company has maintained its BloombergNEF Tier 1 status through Q1 2025, underpinning its bankability for project finance. Talesun, founded in 2010 as a subsidiary of the Zhongli Science and Technology Group, operates at a smaller organizational scale with approximately 501 employees and a capacity of over 5 GW, but claims cumulative shipments of 40 GW since inception and has delivered over 10 GW to European clients alone - including utility-scale projects in Belgium and France. Talesun is equally a BloombergNEF Tier 1 manufacturer and was active at Intersolar Europe 2025, signaling continued investment in the European market. Both companies are headquartered in China and compete in the mid-to-high performance segment of the global solar module market.

On the technology side, DAH Solar has committed heavily to TOPCon cells, which account for 79.6% of its broad 363-panel portfolio, and is widely recognized for its proprietary Full-Screen frameless front-glass design that reduces soiling losses and can improve energy yield. Its bifacial ratio stands at 87%, the highest in this comparison, and maximum output reaches 725 Wp with a peak efficiency of 23.34% and a favorable average temperature coefficient of -0.299%/°C. This bifacial-heavy, high-volume portfolio makes DAH Solar a natural fit for utility-scale ground-mount and large commercial C&I projects. Talesun, by contrast, offers a narrower catalog of 144 panels but achieves a higher peak efficiency of 24.8% and a higher average panel output of 564 Wp, positioning it well in space-constrained applications. TOPCon technology covers 43.75% of Talesun's lineup, and the company's panels excelled across all six key reliability tests in the PV Evolution Labs 2023 report, offering independent validation of durability.

For international buyers choosing between the two, the decision hinges on project type and scale. DAH Solar's deeper bifacial portfolio, larger manufacturing base, and broader geographic reach make it the stronger candidate for large ground-mount and utility projects where bifacial gain and flexible module selection are priorities. Talesun's higher peak efficiency and independently verified reliability give it a competitive edge in rooftop residential and compact C&I deployments where roof area is a binding constraint. Both carry equivalent Tier 1 bankability, making either a defensible choice from a project finance standpoint.
