## Summary

AIKO is a Chinese solar manufacturer founded in 2009, with production sites spanning multiple cities in China - including Yiwu, Foshan, and Zhuhai - and a European research presence through Solarlab AIKO Europe in Freiburg, Germany. The company achieved BloombergNEF Tier 1 bankability status from Q3 2024 onward, and its annual production capacity was estimated at approximately 20 GW as of early 2025. Techwise Solar Technology Co., Ltd. is also China-based but operates at a considerably smaller scale of roughly 1 GW per year, and does not appear on the BloombergNEF Tier 1 list, though it holds standard industry certifications including TUV, CE, ISO, and CGC. On any institutional or bankability metric, AIKO holds a clear and well-documented lead.

AIKO's signature product line is built around its proprietary N-type ABC (All Back Contact) cell technology, which relocates all electrical contacts to the rear of the cell to maximize light capture and reduce resistive losses. The Neostar series has achieved module-level efficiencies above 24%, with the latest generation reaching up to 25.0%, placing AIKO among the most efficient commercially available panel brands in the world. These modules are deployed across residential rooftop, commercial and industrial, and utility-scale ground-mount applications. Techwise Solar covers a wider mix of conventional technologies - PERC, TOPCon, and dual-glass bifacial modules - across cell formats ranging from 166 mm to 210 mm. The company also actively markets ODM and OEM services to Tier 1 brands, which suggests it functions substantially as a contract manufacturer rather than a primary consumer-facing label.

For most international buyers, AIKO is the stronger default choice - it offers verified bankability, independently confirmed efficiency leadership, and a growing track record across financed projects. Techwise Solar may suit procurement teams prioritizing cost or sourcing through OEM channels, but the absence of BloombergNEF Tier 1 recognition limits its suitability for bank-financed installations. The two brands are not interchangeable: AIKO competes at the premium end with a well-established institutional profile, while Techwise Solar is better understood as a volume-oriented supplier with a narrower public track record.
