Catalogue against catalogue
An average over a catalogue describes the range a manufacturer publishes, not the module you would buy. A brand with two flagship panels and eighty older ones averages worse than one that has retired its back catalogue.

Written summary
AIKO is a Chinese solar manufacturer, founded with roots in PERC production before pivoting heavily toward its proprietary ABC (All Back Contact) back-contact cell technology, with cell and module capacity that sources put at roughly 10 GW of ABC output by end of 2023 scaling toward tens of gigawatts as new plants in Jinan and Yiwu ramp through 2025. AIKO has publicized a BloombergNEF Tier 1 designation, though at least one independent reviewer found it absent from a recent BNEF list, so its current standing should be verified directly against the live BNEF registry. WINAICO, by contrast, is the solar arm of Win Win Precision Technology, headquartered in Hsinchu, Taiwan, and traces its module business to around 2007-2008; it has also claimed BNEF Tier 1 status in company press releases, again with at least one reviewer disputing the claim, and its production scale is far smaller, with historical figures in the 150-200 MW range for its core Taiwan facility and only unverified third-party estimates suggesting capacity above 1 GW today. On institutional footprint, AIKO is clearly the larger and more rapidly expanding manufacturer, operating at an industrial scale that dwarfs WINAICO's boutique Taiwanese production base.
In terms of product focus, AIKO's ABC cell lineup, including its Neostar residential modules, is positioned as a premium, high-efficiency option aimed at rooftop installations where aesthetics, shade tolerance, and low degradation matter, and reviewers consistently note strong efficiency paired with a price premium. WINAICO is generally described as a smaller, quality-focused manufacturer using more conventional crystalline silicon module designs, often marketed on reliability, a strong warranty record, and consistent field performance in markets like Australia and the Netherlands, making it a fit for buyers prioritizing a long, well-supported product warranty over cutting-edge cell technology.
For a typical residential buyer in 2025, AIKO is the stronger default if maximum efficiency and modern back-contact technology are priorities and the premium price is acceptable, while WINAICO remains a credible, if lower-profile, alternative for buyers who value a manufacturer's long warranty track record and don't need industry-leading efficiency figures. Neither brand's Tier 1 claim should be taken at face value without checking the current BloombergNEF list, since independent sources diverge on both.
