## Summary

PolyCrown Solar Tech is a Chinese manufacturer founded in 2014 and based in Ningbo, Zhejiang Province. The company operates at a relatively modest scale, with a reported annual production capacity of around 200 MW - well below the multi-gigawatt output of the sector's dominant names. PolyCrown holds standard quality certifications including ISO9001, ISO14001, and TUV IEC61215 and IEC61730, but it does not appear on the BloombergNEF Tier 1 Solar Module Maker List, which limits its appeal for projects requiring bankable, project-finance-ready suppliers. AIKO, by contrast, is a Chinese manufacturer that achieved BloombergNEF Tier 1 status in Q3 2024 and reports a production capacity of roughly 20 GW per year - placing it among the larger dedicated high-efficiency module producers globally. On institutional footprint, AIKO holds a clear and substantial advantage.

In terms of products, PolyCrown offers a broad range of conventional mono and polycrystalline PERC panels spanning from small off-grid wattages up to around 585 W, positioning it as a general-purpose supplier suited to budget-conscious commercial and residential buyers rather than premium segments. AIKO's product story is defined by its proprietary ABC (All Back Contact) cell technology, which relocates all electrical contacts to the rear of the cell to maximize light capture. This approach has allowed AIKO to reach verified efficiencies above 24.8% in commercial production, earning top rankings in multiple independent efficiency surveys for residential panels. AIKO's Gen 3 Infinite Series targets premium rooftop installations where power density per square meter is critical, while its Comet 3N line addresses commercial and industrial ground-mount projects.

For a typical buyer in 2025, AIKO is the stronger default choice for anyone prioritizing long-term energy yield, institutional bankability, and proven high-efficiency technology. PolyCrown may be a reasonable option in price-sensitive contexts where basic PERC performance is sufficient and BloombergNEF Tier 1 status is not a project requirement.
