By the end of 2024 it had built annual ingot and wafer capacity of roughly 80 GW and module capacity of around 4 GW, and by the first half of 2025 cumulative module shipments had exceeded 4 GW. In Solarbe's 2025 Global PV Module Shipment Rankings the company debuted at position 14 in China and 17 globally - a significant first appearance for a brand less than a decade old. A.B. Energy, by contrast, is a small Italian srls with roots in the electric and electronic equipment sector; ENF Solar lists it as a distributor and energy-efficiency service provider rather than a module manufacturer. In terms of institutional footprint, Gokin Solar carries a far stronger profile. Gokin Solar's current product focus is back-contact (BC) module technology, offered in power classes from 480 W to 780 W and covering residential rooftops, commercial and industrial installations, and utility-scale ground mounts; the company also produces TOPCon modules. Its BC series is rated at up to 24.8% conversion efficiency and is backed by a 30-year linear performance guarantee. A.B. Energy does not appear to produce panels under its own brand - based on available sources it sources and resells equipment from third-party manufacturers - which makes a direct product-to-product comparison of cell technology, efficiency ratings, or warranty terms impossible. For a buyer evaluating these two names in 2025, Gokin Solar is the clear choice if purchasing modules from a manufacturer. It offers a documented and growing production base, an expanding global distribution network, and a competitive next-generation BC lineup. A.B. Energy appears to operate as a regional Italian integrator rather than a rival panel brand, so the two are not interchangeable alternatives within the same tier of the solar supply chain. \---LINKS--- \- https://www.pv-magazine.com/2025/12/15/gokin-solar-launches-new-back-contact-solar-module-series/ \| Gokin Solar launches new back-contact solar module series \| article \- https://solarquarter.com/2026/02/09/gokin-solar-enters-solarbes-2025-global-pv-module-shipment-rankings/ \| Gokin Solar enters Solarbe 2025 Global PV Module Shipment Rankings \| article \- https://solarquarter.com/2026/05/11/gokin-solar-hits-3-million-bc-module-milestone-reinforcing-global-pv-supply-capacity/ \| Gokin Solar hits 3-million BC module milestone \| article \- https://www.enfsolar.com/a-b-energy \| A.B.
