## Summary

AIKO (formally Shanghai Aiko Solar Energy Co., Ltd.) is a Chinese manufacturer founded in 1996 and listed on the Chinese stock exchange, with operations anchored in Guangdong and production sites spanning Yiwu, Foshan, Zhuhai, and Jinan. The company has achieved BloombergNEF Tier 1 bankability status and is investing heavily to expand its manufacturing footprint, with pv-tech.org reporting an 11 GW capacity upgrade as part of a full transition to its proprietary ABC cell technology. Powitt Solar (Changzhou Powitt Solar Co., Ltd.) is a smaller Chinese manufacturer founded around 2007 and based in Changzhou, Jiangsu, with roughly 1 to 1.2 GW of annual production capacity across factories in Wuxi. It holds TUV and CQC certifications but does not appear on the BloombergNEF Tier 1 list based on available public sources. AIKO carries the stronger institutional footprint by a clear margin.

AIKO has built its identity around ABC (All Back Contact) cell technology, in which both electrical contacts are moved to the rear of the cell - eliminating front-side shading losses and enabling the company to claim world-record module efficiencies above 25%, as confirmed by pv-magazine.com coverage from Intersolar 2024. This positions AIKO firmly in the premium residential and commercial rooftop segment where space is constrained and buyers prioritize top-tier output per square meter. Powitt Solar offers N-type TOPCon panels in the 580 W to 730 W range, covering both residential and commercial applications, with a reported fully bifacial catalog. The company has a visible OEM and white-label dimension to its business - supplying panels rebranded under other names - a model common among mid-tier Chinese manufacturers competing on price rather than prestige.

For a typical buyer in 2025 who prioritizes verified bankability, leading-edge efficiency, and brand continuity over a 25-30 year system life, AIKO is the clearer choice. Its Tier 1 status matters for project financing, and its ABC technology advantage is a genuine differentiator rather than a marketing claim. Powitt Solar may suit cost-sensitive buyers or those purchasing through a trusted installer who has personally vetted the brand, but the absence of Tier 1 recognition and its smaller scale introduce a higher due-diligence burden. The two brands serve meaningfully different buyer profiles and should not be treated as equivalent options.
