## Summary

AIKO (formally Shanghai Aiko Solar Energy Co. Ltd.) is a Chinese manufacturer headquartered in Shanghai, founded in 2009. Despite being a relatively young company, it achieved BloombergNEF Tier 1 bankability status in Q3 2024 and has a confirmed annual production capacity of approximately 20 GW according to the BNEF Tier 1 lists covering 2025 and 2026. Risen Energy is headquartered in Ningbo, Zhejiang Province, and has operated since 2002, listing on the Shenzhen Stock Exchange in 2010. Risen has maintained BloombergNEF Tier 1 status for considerably longer and reports an annual module production capacity exceeding 48 GW, making it a substantially larger manufacturer by volume. On the dimension of institutional track record and bankability history, Risen holds the stronger position.

AIKO has staked its identity on proprietary ABC (All Back Contact) cell technology, which relocates both positive and negative contacts to the rear of the cell, eliminating front-side shading losses. The result is some of the highest panel efficiencies commercially available - the Neostar 2P reaches 24.3% and select models claim up to 25.2%, alongside a favourable temperature coefficient of -0.26 per cent per degree Celsius. The premium Neostar series carries a 25-year product warranty and a 30-year performance warranty, while the more affordable Comet and Stellar lines step down to a 15-year product warranty. These characteristics make AIKO particularly compelling for space-constrained residential rooftops where every watt per square metre matters. Risen offers a broader portfolio spanning PERC and TOPCon cell technologies, covering residential, commercial and industrial (C&I) segments as well as large utility-scale ground-mount projects. The Risen Titan series carries a 25-year product warranty and all lines guarantee 25 to 30 years of performance output. Risen's longer operating history and larger distribution network give it an edge in markets where servicing and local installer familiarity are important procurement criteria.

For a typical international buyer, the choice narrows to one question - is premium efficiency worth a higher upfront cost? On space-limited rooftops or wherever shade is a factor, AIKO's ABC technology delivers a meaningful advantage. For ground-mount utility projects or standard commercial installations where surface area is not a constraint, both manufacturers are largely interchangeable, and local pricing, installer relationships, and logistics will likely be the deciding factors.
