## Summary

DAH Solar is a Chinese manufacturer founded in 2009 and headquartered in Hefei, Anhui Province. It holds a confirmed position on the BloombergNEF Tier 1 list as of Q1 and Q3 2025, with an annual module production capacity of approximately 10 GW and a 7.5 GW cell line. Astronergy - formally Chint New Energy Technology Co., Ltd. - was founded in 2006 in Haining, Zhejiang, and operates as a subsidiary of CHINT Group, a diversified energy conglomerate established in 1984 with a presence in over 140 countries. Astronergy reached a 2025 module production capacity of around 35 GW and ranked among the top six on the 2023 BNEF bankability index; its shipments exceeded 25 GW in 2023 and 18.7 GWp in the first half of 2025 alone. On institutional scale and supply-chain depth, Astronergy holds the stronger footprint.

Both brands have converged on n-type TOPCon as their primary cell technology. DAH Solar's signature offering is its patented Full-Screen module line - a frameless front-side design that reduces dust and water accumulation - targeting residential rooftops, commercial installations, and building-integrated photovoltaics. The V6 Full-Screen series, launched in 2025, crossed the 24% module efficiency threshold and received a "Top Performer" certification from Kiwa PVEL. Astronergy's ASTRO N series spans a broader range, from compact 460 W residential panels confirmed at roughly 23% efficiency to the 650 W-class ASTRO N7 2.0 aimed at utility-scale and commercial and industrial projects. Astronergy's performance warranty is additionally backed by Munich Re reinsurance, which reduces financial risk for project financiers.

For a typical buyer in 2025, Astronergy is the lower-risk default thanks to its larger production base, stronger bankability ranking, broader product portfolio, and third-party-backed warranty. DAH Solar is a credible alternative - and may be preferable - for installers specifically seeking a differentiated frameless module design or BIPV applications where the Full-Screen anti-dust performance adds measurable yield value.
