## Summary

AIKO is a Chinese manufacturer headquartered in Guangdong Province, founded in 2009. The company achieved BloombergNEF Tier 1 bankability status as of Q3 2024 and maintained it through 2025 and into 2026, confirming that major project-finance lenders are prepared to back installations using its modules. Its annual production capacity stood at approximately 20 GW in early 2025, with expansion underway at new facilities including a major site in Jinan. KDM Kingdom Solar - operating as Zhejiang Kingdom Solar Energy Technic Co., Ltd. - is based in Linhai City, Zhejiang Province, and self-reports annual module output of around 1 GW. The company carries certifications including IEC 61215, IEC 61730, TUV, and ISO 9001, and claims distribution across more than 100 countries, but no Tier 1 BNEF classification has been confirmed in publicly available sources. By institutional footprint, AIKO is substantially the larger and more bankable of the two.

AIKO's product range centers on its proprietary ABC (All Back Contact) cell architecture, which places all electrical contacts on the rear of the cell, eliminating front-side shading losses while combining n-type silicon with amorphous-silicon passivation layers. Independent reviewers confirm module efficiencies above 24% and a temperature coefficient of roughly -0.26%/°C, both among the best in mass commercial production as of 2025. This positions AIKO firmly in the premium residential and commercial rooftop segment, where buyers pay a meaningful premium over mainstream TOPCon products for higher power density and better performance in diffuse light and high temperatures. KDM Kingdom Solar's catalog focuses on conventional mono- and polycrystalline modules in the 530-550 W class, aimed at cost-sensitive commercial and light industrial buyers, with some European distribution through a partnership with Systems Technology GmbH in Germany, though independent field-performance data remains scarce.

For a typical buyer in 2025, AIKO is the more defensible choice where roof area is constrained, project financing requires confirmed Tier 1 status, or long-term warranty credibility matters. KDM Kingdom Solar may suit buyers on tighter budgets pursuing smaller, self-financed installations where bankability is a secondary concern. The two are not interchangeable: AIKO occupies a distinct premium tier, while KDM competes on price in mid-market segments.
