Written summary
AIKO is a Chinese solar module manufacturer headquartered in Zhejiang province, established as Zhejiang Aiko Solar Technology Co., Ltd. The company achieved BloombergNEF Tier 1 status beginning in Q3 2024 and reported a production capacity of approximately 20 GW as of early 2025. DAON is not a standalone company but rather the back-contact product brand of DAS Solar, a Chinese manufacturer headquartered in Quzhou, Zhejiang. DAS Solar has secured four consecutive BloombergNEF Tier 1 recognitions through 2025, reflecting sustained bankability. Both brands carry credible institutional standing, but AIKO has built a more internationally visible independent identity - particularly in Australia, the UK, and European markets - while DAON operates as one product line within DAS Solar's broader portfolio.
AIKO's defining technology is its proprietary ABC (All Back Contact) cell architecture, which relocates both electrode contacts to the rear of the cell to maximize light absorption. The flagship Neostar series reaches efficiencies reported at up to 25.0%, with a temperature coefficient around -0.26%/°C that holds up well in hot climates. AIKO positions its panels primarily for premium residential rooftops where space is limited and aesthetics matter, though the company also offers modules for commercial and utility-scale applications. DAON, by contrast, is DAS Solar's back-contact sub-brand within a "one core, three branches" roadmap built on a TOPCon foundation - the other branches being TSiP and SFOS cell technologies. DAS Solar's broader catalog targets utility-scale ground mounts and large commercial rooftops as well as residential segments.
For a typical buyer in 2025, AIKO is the more transparent choice in premium residential contexts - independent lab tests, installer-community awards, and multiple market-level reviews provide a clearer performance picture. DAON modules may appeal to buyers already working with DAS Solar's supply chain, but the brand carries less standalone third-party coverage, so due diligence on specific module datasheets and project references is advisable before committing at scale.
