## Summary

AKCOME is a Chinese manufacturer headquartered in Zhejiang province, with roots in photovoltaics reaching back to the early 2000s and operations spanning more than 30 countries across a workforce of over 6,000 people. The company holds Tier 1 bankability recognition from BloombergNEF and maintains an annual PV module production capacity of approximately 3.8 GW. Exiom Solution is a Spanish manufacturer founded in 2009 in Asturias, with primary manufacturing in China at around 2.7 GW of capacity and a new 500 MW plant in Langreo, Spain, opened in late 2024 through a strategic alliance with Iberdrola - making it one of the very few European-headquartered names to appear on the BloombergNEF Tier 1 list. On sheer production scale and global distribution breadth, AKCOME carries the stronger institutional footprint, though Exiom holds a meaningful structural advantage within European supply chains.

AKCOME's catalog is oriented around HJT cell technology, with bifacial modules spanning residential rooftop and utility-scale ground-mount applications. The company markets distinct series targeting high-efficiency buyers comfortable paying a modest premium for HJT's temperature and low-light performance characteristics. Exiom takes a broader technology approach, offering modules built on PERC, TOPCon, HJT, and IBC cells across a wide power range that can serve small residential systems through large commercial and industrial projects. Their N-type TOPCon line has been highlighted for residential and commercial rooftop buyers looking for competitive efficiency at a price point below premium HJT.

For a typical buyer in 2025, geography largely determines the better fit. Asia-Pacific and global markets with established distributor networks will generally find AKCOME more accessible, backed by its larger scale and HJT specialization. European buyers - especially those sourcing for commercial or industrial projects - are likely to favor Exiom for its European production base, Iberdrola partnership, and alignment with emerging domestic-content preferences. Neither brand dominates universally; local support quality and warranty serviceability in the buyer's region should be the deciding factors.
