## Summary

DAH Solar is a Chinese manufacturer headquartered in Hefei, Anhui province, and has appeared on BloombergNEF's Tier 1 PV module list consistently through at least Q3 2025. The company operates module production capacity of roughly 10 GW per year and has built its identity around its proprietary "Full-Screen" frameless module design, which it claims reduces dust-accumulation losses associated with conventional framed panels. AIKO Solar - formally Shanghai Aiko Solar Energy Co., Ltd. - is a Guangdong-based manufacturer that attained BloombergNEF Tier 1 status in 2024 and shipped roughly 12 GWp in the first half of 2025 alone, supported by an expanding multi-gigawatt manufacturing footprint that includes a major new facility in Jinan. By shipment momentum and institutional recognition in 2025, AIKO carries the stronger global footprint of the two.

DAH Solar's principal product line centers on N-type TOPCon cells packaged in its Full-Screen dual-glass bifacial format, covering power classes from roughly 420 W to 630 W and confirmed module efficiency up to around 23%. That configuration suits commercial rooftops and utility-scale ground mounts where bifacial energy gain and long-term yield matter; the company backs its DHN series with a 30-year linear performance warranty. AIKO has pursued a markedly different technology path, commercializing ABC (All Back Contact) cells that relocate both electrical contacts to the rear of the cell, eliminating shading losses from front-side busbars. Its Neostar series addresses premium residential rooftops while the Comet 3N targets commercial and industrial projects; confirmed mass-production module efficiency has reached 24.8%, placing AIKO among the highest-efficiency volume manufacturers in the world and at the top of the TaiyangNews Top Solar Modules ranking for 34 consecutive months through 2025.

For a typical buyer in 2025, AIKO is the more compelling choice where peak efficiency per square meter is a priority - constrained rooftops, high-irradiance markets, or installations where fewer panels are preferred. Its 2025 SolarQuotes Installers' Choice win points to strong field satisfaction as well. DAH Solar is a well-bankable, warranty-competitive alternative particularly suited to buyers drawn to TOPCon bifacial economics or the Full-Screen aesthetic, but AIKO currently holds a clear efficiency and market-ranking edge.
