## Summary

DAS Solar is a Chinese photovoltaic manufacturer headquartered in Quzhou, Zhejiang Province. The company is recognized as a Tier 1 supplier and has reported annual module production capacity in the range of approximately 25 GW, supported by a global factory network. In April 2025 it announced plans for a 3 GW module assembly plant in eastern France, signaling a push to localize supply ahead of evolving European content requirements. TCL Zhonghuan, one of China's largest wafer producers, separately entered exclusive acquisition talks for a controlling stake in DAS Solar, a move that would substantially deepen its industrial backing. AIKO (Shanghai Aiko Solar Energy Co., Ltd.) was founded in 2009 and operates gigafactories across Yiwu, Foshan, Zhuhai, and Jinan, with an R&D presence in Freiburg, Germany. AIKO achieved BloombergNEF Tier 1 status in 2024, confirming bankability for project finance purposes. Both are recognized Tier 1 Chinese manufacturers, but AIKO currently carries a stronger profile among premium-segment installers internationally, particularly in Australia and Europe.

DAS Solar has anchored its lineup around TOPCon N-type cell technology, with a research roadmap targeting cell efficiencies above 26%. Its D-Mini residential series spans roughly 410 W to 435 W at module efficiencies up to approximately 22.3%, and N-type bifacial modules placed as top performers in five of seven test categories by PV Evolution Labs - a result that supports both rooftop and commercial ground-mount positioning. AIKO has built its identity around All Back Contact (ABC) cell architecture, which relocates all metal contacts to the rear of the cell to eliminate front-side shading losses. The NeoStar series targets premium residential rooftops with module efficiencies consistently above 24%, and AIKO has held the top spot in Taiyangnews global module efficiency rankings since March 2023. The larger-format Comet line is aimed at commercial rooftops and utility-scale ground mounts and is sold directly to EPC contractors.

For a typical buyer in 2025, the choice turns on efficiency priorities versus budget. AIKO is the stronger default for space-constrained rooftops or buyers seeking the highest certified efficiency per square meter. DAS Solar is a credible and cost-competitive alternative in the TOPCon mainstream - well-suited to price-sensitive commercial projects or markets where AIKO's premium carries a meaningful cost premium. At utility scale, where cost per watt dominates, the two brands are closer to interchangeable given their shared Tier 1 bankability.
