## Summary

AIKO is a Chinese solar manufacturer founded in 2019 and headquartered in Guangzhou. It attained BloombergNEF Tier 1 bankability status in 2024 and has been rapidly scaling production, with PV Tech reporting an 11 GW ABC cell capacity upgrade underway. Weran Solar is a smaller Chinese manufacturer established in 2015 and based in Shanghai, with a reported annual production capacity of around 2 GW. Weran holds ISO, TUV, CE, and CSA certifications and operates as an authorized LONGi distributor in several markets, but no BloombergNEF Tier 1 listing was found for the company. In terms of institutional footprint, AIKO carries a meaningfully larger profile with confirmed bankability, broader independent coverage, and a growing presence across Australia, Europe, and Southeast Asia.

AIKO's flagship technology is its proprietary ABC - All Back Contact - cell architecture, an N-type design that routes all electrical contacts to the rear surface to eliminate front-side shading losses. The company has held the top position in TaiyangNews global efficiency rankings for over 34 consecutive months and won the 2025 SolarQuotes Installers' Choice Awards. Its panels target premium residential rooftops and commercial and industrial installations where maximum energy yield per square meter justifies a higher upfront cost. Weran Solar covers a broader product mix including PERC, HPBC, and N-TOPCon modules, and at SNEC 2025 it showcased an HPBC 2.0 module. The company is positioned as a mid-range supplier serving residential, commercial, and industrial buyers across emerging markets, particularly in Africa, the Middle East, and South America.

For a buyer seeking the highest-efficiency panels with verified bankability and strong installer support networks, AIKO is the clearer default in 2025. Weran Solar may suit cost-sensitive projects in emerging markets where LONGi-compatible supply chains and competitive pricing outweigh the need for cutting-edge efficiency, though buyers should conduct their own due diligence on long-term service availability given the absence of a confirmed Tier 1 rating.
