Energy srls is a small Italian-based solar components reseller rather than a panel manufacturer in the conventional sense. Based on available information, the company acts as a distributor of third-party brands - including REC, JA Solar, Trina, and LONGi - rather than producing modules under its own name. No Tier 1 or BloombergNEF bankability listing could be found for A.B. Energy, and no independent production capacity figure is on record. Exiom Solution S.A., by contrast, is a genuine module manufacturer headquartered in Asturias, Spain, with roots going back to the early 2000s as one of the few Western European companies to vertically integrate cell-to-module production. Exiom achieved a Bloomberg NEF Tier 1 rating - confirming bankability for project financing - and operates roughly 2.7 GW of manufacturing capacity in China alongside a 500 MW TOPCon assembly plant it opened in Langreo, Spain, in partnership with Iberdrola. On institutional footprint, Exiom is the stronger and more clearly defined industrial entity. Exiom's own product catalog spans modules from around 140 W to over 700 W, covering residential rooftops, commercial flat roofs, and utility-scale ground mounts. The China lines have historically leaned on PERC technology, while the new Langreo facility is dedicated to n-type TOPCon modules - a higher-efficiency cell architecture increasingly favored in European utility and commercial projects. Its Iberdrola partnership gives the brand additional credibility for large-scale procurement in the Iberian and broader EU markets. A.B. Energy, as a reseller, does not maintain a proprietary product family; buyers purchasing through it are ultimately acquiring panels from whichever third-party manufacturer A.B. Energy sources from at a given time. For a typical buyer in 2025 evaluating these two names side by side, Exiom is the clearer choice as a manufacturer with traceable production capacity, a confirmed Tier 1 bankability rating, and an expanding European industrial presence. A.B. Energy may serve as a convenient local reseller for customers in Italy, but it does not offer the same warranty backstop, product consistency, or institutional track record that a dedicated manufacturer provides. \---LINKS--- \- https://www.pv-tech.org/iberdrola-exiom-to-build-500mw-topcon-module-manufacturing-in-spain/ \| Iberdrola and Exiom to build 500MW TOPCon module plant in Spain \| article \- https://www.pv-tech.org/iberdrola-exiom-receive-first-machinery-shipment-to-500mw-topcon-module-assembly-plant-in-spain/ \| Iberdrola and Exiom receive first machinery for 500MW TOPCon plant \| article \- https://comparepv.com/reviews/exiom \| Exiom Solar Panels Review 2026 - Pros Cons and Specs \| review \- https://www.enfsolar.com/a-b-energy \| A.B.
