## Summary

AIKO (trading internationally as Aiko Solar or Aiko Energy) is a Chinese manufacturer headquartered in Guangzhou that has built its identity around proprietary ABC (All Back Contact) cell architecture, a design that places all electrode contacts on the rear of the cell to eliminate front-side shading losses. The company achieved BloombergNEF Tier 1 status in Q3 2024, placing it among the top 2% of solar manufacturers globally by bankability criteria, and its manufacturing capacity for ABC modules has been scaling into the multi-gigawatt range. Ruihuang New Energy and Science (RHsolar) is a considerably smaller Chinese manufacturer founded in 2018 and based in Xinyu, Jiangxi Province, with a stated annual production capacity of around 3 GW. It does not appear on published BloombergNEF Tier 1 lists, and independent third-party coverage of the brand is scarce. In terms of institutional footprint and verifiable financial backing, AIKO holds a substantially stronger position.

AIKO's catalog is anchored by its Neostar series, which uses ABC cell technology to reach module efficiencies confirmed around 24-25% in multiple independent benchmarks - among the highest for any mass-produced residential panel - combined with a notably low temperature coefficient that limits power loss on hot days. These characteristics make AIKO panels particularly well-suited to premium residential rooftops and space-constrained commercial installations where maximum yield per square meter is the priority. Ruihuang's portfolio is far broader in technology terms, spanning older polycrystalline and PERC variants alongside newer bifacial and TOPCon modules across a wattage range from 50 W up to 660 Wp. This breadth positions the brand as a flexible OEM-style supplier targeting budget commercial, small-scale utility, and off-grid projects rather than premium branded residential markets.

For a typical buyer in 2025, AIKO is the clearer default when performance, long-term bankability, and access to independently verified warranties matter - especially on premium residential or space-limited commercial sites where its ABC efficiency advantage is most tangible. Ruihuang may appeal to cost-driven procurement on smaller or off-grid projects where Tier 1 status is less critical, but the absence from BloombergNEF lists and limited independent review coverage introduces financing and resale risk that buyers should weigh carefully before committing.
