It may be a small regional distributor, a white-label reseller, or an emerging entrant not yet covered by the main trade press. Without verifiable information, no meaningful product or company profile can be responsibly drawn for ASM. Exiom Solution, by contrast, is a well-documented Spanish manufacturer founded in 2009 and headquartered in Asturias. It holds Tier 1 status from Bloomberg New Energy Finance, one of a very small number of European-owned brands to appear on that list. Its primary manufacturing base consists of roughly 2.7 GW of annual capacity in China, supplemented by a 500 MW plant in Langreo, Asturias, opened in partnership with Iberdrola and representing the first large-scale solar module factory on Spanish soil. This combination of European roots and certified bankability gives Exiom a stronger institutional footprint than most regional competitors. On the product side, Exiom's catalogued portfolio spans roughly 270 W to 605 W and is dominated by PERC-based monocrystalline modules, with a growing share of TOPCon panels. Bifacial options are prominent and suit ground-mounted commercial and utility-scale installations. The brand also addresses residential rooftops with compact all-black variants. Its panels carry an ISO 14001 environmental certification and, according to ComparePV's 2026 analysis, an average performance warranty of around 29 years. For any buyer in 2025-2026 who needs a financeable, European-origin module with documented supply-chain transparency, Exiom is a defensible choice. ASM cannot be compared on equal terms until it establishes a traceable public profile. \---LINKS--- \- https://comparepv.com/reviews/exiom \| Exiom Solar Panels Review 2026: Pros, Cons and Specs \| review \- https://www.solarfeeds.com/biz/exiom-solution-s-a/ \| Exiom Company Overview: Production Capacity, Is it Tier 1? \| article \- https://solarbusinesshub.com/2023/02/23/iberdrola-and-exiom-to-build-first-large-photovoltaic-solar-panels-factory-in-spain/ \| Iberdrola and Exiom to build first large PV factory in Spain \| article \- https://energypal.com/best-solar-panels-for-homes/exiom-solution \| Exiom Solution - Best Solar Panels for Homes 2025 - EnergyPal \| review Sources: \- \[Exiom Solar Panels Review 2026: Pros, Cons & Specs \| ComparePV\](https://comparepv.com/reviews/exiom) \- \[Exiom Company Overview \| Production Capacity, Is it Tier 1?\](https://www.solarfeeds.com/biz/exiom-solution-s-a/) \- \[Iberdrola and Exiom to build first large photovoltaic solar panels factory in Spain\](https://solarbusinesshub.com/2023/02/23/iberdrola-and-exiom-to-build-first-large-photovoltaic-solar-panels-factory-in-spain/) \- \[Exiom Solution - Best Solar Panels for Homes 2025 - EnergyPal\](https://energypal.com/best-solar-panels-for-homes/exiom-solution) \- \[Exiom Solution S.A. \| Solar Panels \| Spain - ENF Solar\](https://www.enfsolar.com/exiom-solution) Written by claude-sonnet from the figures above. ## Other comparisons - [ASM vs A.B.
