Written summary
Tongwei is a Chinese manufacturer headquartered in Chengdu, Sichuan, founded in 1984 as a fish-feed and aquaculture business before pivoting aggressively into solar over the past decade. It holds BloombergNEF Tier 1 status and by 2025 had built one of the largest cell and module production bases in the world, with reported module capacity in the range of 60-90 GW per year and cumulative shipments that crossed the 100 GW milestone. A.B. Energy, by contrast, is a small Italian company - listed on ENF Solar as a seller and distributor rather than a panel manufacturer - with roots in electrical and electronic equipment distribution and a stated mission around energy efficiency consultancy and resale. No credible industry source places A.B. Energy on any Tier 1 or bankability list. Tongwei has an incomparably stronger institutional footprint.
On the product side, Tongwei's commercial catalog centers on its TNC series of n-type TOPCon modules, available in large-format G12 wafers, with bifaciality factors and efficiency ratings verified by third-party labs and reported in publications such as pv-magazine. The company also runs pilot HJT lines under its THC branding and is actively developing xBC and perovskite-tandem roadmaps, positioning it for utility-scale ground mounts and increasingly for premium commercial rooftops where high-watt modules reduce balance-of-system costs. A.B. Energy's product offering, based on available information, consists of sourced or resold panels from third-party manufacturers rather than any proprietary module family, making a technology-level comparison impossible without knowing which brands it distributes at any given time.
For any buyer operating at scale in 2025 - whether a utility developer, a commercial EPC, or an installer seeking bankable equipment - Tongwei is the clear default choice, backed by documented production capacity, third-party efficiency data, and Tier 1 status. A.B. Energy may serve a role as a local Italian distributor for smaller projects, but it cannot be evaluated or compared as a manufacturer in the same frame.
