## Summary

AKCOME is a Chinese manufacturer founded in 2006 and headquartered in Hangzhou, Zhejiang Province, where it has been listed on the Shenzhen Stock Exchange since 2011. It holds Bloomberg NEF Tier 1 bankability status and operates module production capacity estimated at several gigawatts annually, alongside a significant solar mounting structures business serving more than 80 countries. Tongwei, founded in 1982 in Chengdu, Sichuan, originated as an agricultural conglomerate before pivoting into solar energy, becoming one of the most vertically integrated solar producers in the world - covering polysilicon, wafers, cells, and modules. As of 2025, Tongwei reports module capacity exceeding 90 GW and cell capacity above 150 GW, earned Bloomberg NEF Tier 1 recognition in Q1 2025, holds an "A" PV ModuleTech bankability rating, and ranks among the Fortune Global 500 - giving it a substantially larger and better-documented institutional footprint than AKCOME.

AKCOME made early investments in HJT (heterojunction) cell technology and distributes a residential and commercial module lineup globally, complemented by aluminium racking and mounting systems as a second revenue line. However, the brand was removed from TaiyangNews Top Solar Modules tracking in January 2025 after its website became inaccessible, which raises questions about current market visibility outside core regions such as Australia. Tongwei's TW Solar module line centers on N-type TOPCon technology, including the recently launched G12R series aimed at utility-scale ground-mount and large commercial applications. Select TW Solar models have earned Top Performer status in PVEL scorecards, and the brand's fully integrated supply chain - from raw polysilicon through finished modules - strengthens both cost control and quality consistency.

For most buyers in 2025, Tongwei is the stronger default choice: its verified production scale, Fortune Global 500 standing, confirmed bankability ratings, and independently validated TOPCon products make it well-suited to financed or utility-scale projects. AKCOME can still be a credible option in markets where it maintains active distribution, and its HJT focus may appeal to buyers seeking that specific cell technology, but the uncertainty around its global market presence adds measurable risk for large procurements.
