## Summary

AIKO is a Chinese photovoltaic manufacturer headquartered in Guangdong, China, with roots going back to 2009 and a publicly listed parent entity on the Shanghai Stock Exchange. The company achieved BloombergNEF Tier 1 status in Q3 2024, confirming its bankability - meaning independent commercial banks have financed projects using its modules on a non-recourse basis. AIKO's annual production capacity is reported at over 20 GW and expanding rapidly toward a stated target of approximately 35 GW. Talesun, founded in 2010 as part of the Zhongli Group and headquartered in Jiangsu province, has maintained BloombergNEF Tier 1 status continuously through multiple quarters in 2024 and 2025, and has accumulated more than 36 GW of cumulative module shipments deployed across the US, Europe, South America, and Asia. In terms of time on the Tier 1 list and geographic reach, Talesun carries a somewhat more established institutional track record.

AIKO's defining differentiator is its proprietary ABC (All Back Contact) cell technology, which removes metal busbars from the front surface, combines amorphous silicon passivation with an N-type substrate, and pushes module efficiency above 24% - placing AIKO consistently among the top performers in global efficiency rankings. A temperature coefficient of around -0.26%/°C means the panels hold output better during hot summer conditions. The product range is positioned primarily at space-constrained residential rooftops and commercial C&I installations where yield-per-square-meter justifies a premium price point. AIKO backs its panels with a 30-year product warranty, which is longer than most competitors. Talesun's lineup is broader in scope, spanning power classes from around 280 W to over 700 W, and is built primarily on PERC and bifacial technologies, with the flagship BISTAR series reaching up to approximately 21.6% efficiency. The company earned favorable reliability scores in PV Evolution Labs' 2023 testing and serves residential, commercial, and utility-scale ground-mount segments with competitive pricing.

For international buyers, the choice between the two depends primarily on project type and budget. AIKO is the stronger option when roof space is tight and maximum energy density is the priority, though its premium pricing demands careful financial modeling. Talesun is a well-rounded mid-premium choice suited to a wider range of project sizes, particularly utility and commercial installations where cost-per-watt matters as much as peak efficiency. Both brands hold Tier 1 bankability status and both are credible long-term suppliers - buyers who are indifferent to peak efficiency will find Talesun the more cost-effective default, while those chasing top performance from a compact footprint should look at AIKO.
