## Summary

Exiom is a Spanish solar module manufacturer founded in 2009 and headquartered in Asturias, Spain. The company has earned BloombergNEF Tier 1 bankability status, making it one of the very few European-domiciled manufacturers to appear on that list - a meaningful distinction in a ranking dominated by Asian producers. It operates automated production facilities in China, with production capacity reported at approximately 2.7 GW there, alongside a newer 500 MW plant being brought online in Langreo, Spain. Hyundai Energy Solutions - now branded HD Hyundai Energy Solutions - is a South Korean manufacturer that has produced solar panels since 2004 and operates under the HD Hyundai Group, a Fortune Global 500 conglomerate with over $472 billion in total group sales. Hyundai holds Tier 1 bankable status and earned a PVEL 2025 Top Performer designation. In terms of institutional scale and global brand recognition, Hyundai carries the stronger corporate footprint by a considerable margin.

On the product side, Exiom's catalog runs from roughly 270W to 605W, with PERC cells making up the bulk of its portfolio and a growing TOPCon segment offering higher efficiency at the top end. Its modules are principally aimed at the European residential and light commercial market, with an emphasis on locally shorter supply chains. Hyundai Energy Solutions fields three main residential lines: the XG series (PERC-based, 350W-375W range, suited to standard rooftops), the bifacial YH series (better suited for ground-mount or open-rack residential installs where rear-side gain is achievable), and the newer NF series built on N-Type TOPCon technology, reaching efficiency ratings up to approximately 22.5%. Hyundai is actively expanding its U.S. presence and participates in large industry events such as RE+ to reinforce that position.

For most buyers outside of Spain or southern Europe, Hyundai Energy Solutions is the more accessible and better-documented choice, supported by a wider installer network and more independently published test data. Exiom is a compelling option for European residential projects where provenance and a shorter supply chain matter, and its Tier 1 rating makes it financeable for small commercial work. The two brands are not truly interchangeable - Hyundai has broader geographic reach and a more diversified product ladder, while Exiom's value is tied closely to the European market context.
