## Summary

Jinko Solar is a Chinese, NYSE-listed module manufacturer with annual production capacity of roughly 120 GW and BNEF Tier 1 status carrying an AAA bankability rating from both BloombergNEF and PV Tech's ModuleTech survey, making it one of the most financially robust and widely bankable suppliers in the industry. In the first half of 2025 Jinko overtook Longi to become the world's largest module shipper, with TOPCon cells accounting for more than 94 percent of its output. WINAICO, by contrast, is a Taiwanese brand, a wholly owned subsidiary of Win Win Precision Technology, operating on a far smaller scale, with independent estimates putting its annual manufacturing capacity at only around 180-200 MW. WINAICO is also listed as a BNEF Tier 1 manufacturer according to its own press releases, though some independent reviewers question that status given the company's size and structure. On institutional footprint, production scale and capital-markets visibility, Jinko holds a clearly stronger position.

In practice the two brands serve different buyer segments. Jinko's lineup is built around TOPCon n-type cells, notably the Tiger Neo series (including Tiger Neo 3.0, rated up to 670 W), and spans utility-scale ground-mount farms, commercial and industrial rooftops, and residential systems, backed by aggressive pricing and broad distribution across European markets. WINAICO focuses narrowly on premium residential and small commercial rooftop installs, having migrated its entire portfolio from PERC to n-type technology between 2023 and 2025, including TOPCon modules (NCX series, up to 525 W at 22.1 percent efficiency) and a heterojunction HJT module rated 515 W at 23.2 percent efficiency, supported by extended 30-year product and performance warranties.

For a buyer prioritizing scale, lowest cost per watt, or utility-scale bankability, Jinko Solar is the more straightforward default given its production footprint and Tier 1 standing. WINAICO can be a reasonable choice for residential customers who value build quality, a long warranty, and a premium niche reputation, though its smaller manufacturing base means less supply flexibility and typically a higher price per watt.
