## Summary

DAH Solar is a Chinese manufacturer headquartered in Hefei, Anhui, that has built a reputation around its proprietary Full-Screen module design - a frameless, frameless-front approach that reduces dust accumulation and improves bifacial yield. The company has maintained a consistent position on BloombergNEF's Tier 1 PV module list throughout 2025, including Q1, Q3, and Q4 rankings, and has targeted a combined cell and panel production capacity in the multi-gigawatt range. Q-Cells operates under South Korea's Hanwha Group, which acquired the original German brand Q-Cells SE (founded 1999 in Thalheim, Germany) in 2012; the technology headquarters remains in Thalheim while the global executive center is in Seoul. Q-Cells also holds BloombergNEF Tier 1 status and has substantially expanded its manufacturing footprint in the United States, with its Dalton, Georgia facility scaled to approximately 5.1 GW and a new Cartersville plant adding roughly 3.3 GW, making it the largest solar manufacturing presence in the Western Hemisphere. On institutional footprint - brand recognition in regulated Western markets, domestic US manufacturing, and supply-chain depth - Q-Cells holds the stronger position.

DAH Solar's flagship product line centers on its Full-Screen TOPCon modules, with the latest V6 series reaching 650 W and an efficiency of around 24%, aimed at both residential rooftops where the clean frameless aesthetic is valued and commercial ground-mount projects seeking high bifacial output. Q-Cells competes primarily with its Q.ANTUM NEO platform, an N-type TOPCon-based technology that pushes efficiencies toward 22.5% in its Q.TRON G2 residential series, while its larger format modules serve utility-scale and commercial segments. Q-Cells is generally positioned as a premium-value option - priced meaningfully below ultra-premium brands like Maxeon but above entry-level Chinese competitors - and SolarReviews ranked it third among all manufacturers for 2025. DAH Solar typically occupies a cost-competitive niche while offering differentiated technology through its Full-Screen IP.

For a typical buyer in 2025, Q-Cells is the lower-risk default in North American and Western European residential markets: its domestic US production insulates buyers from tariff exposure, its 25-year product warranty is well-documented, and its installer network is broad. DAH Solar is a credible alternative - particularly where price sensitivity is higher or where the Full-Screen bifacial design suits a specific roof or ground-mount configuration - but buyers outside established DAH distribution regions should verify local warranty support before committing.
