Catalogue against catalogue
An average over a catalogue describes the range a manufacturer publishes, not the module you would buy. A brand with two flagship panels and eighty older ones averages worse than one that has retired its back catalogue.

Written summary
Exiom Solution is a Spanish manufacturer founded in 2009 and headquartered in Oviedo, Asturias. The company operates automated production facilities in China and has partnered with Iberdrola to develop what is designed to be the first large-scale solar panel factory on Spanish soil, located in Langreo. Exiom is widely cited as one of the very few European-headquartered brands to hold Tier 1 status - a meaningful distinction in a market dominated by Chinese supply chains. AIKO Solar is a Chinese manufacturer based in Shanghai that emerged as a focused high-efficiency cell developer around 2019-2021, achieved BloombergNEF Tier 1 status in Q3 2024, and has grown rapidly into a global commercial operation spanning more than 20 international offices, including R&D centers in Europe. In terms of institutional scale and global distribution reach, AIKO currently carries the stronger footprint.
Exiom's catalog covers residential, commercial, and industrial segments across a wide power range, drawing on multiple cell generations including TOPCon, HJT, IBC, and bifacial configurations. That technology breadth makes Exiom a practical single-supplier option for integrators who need procurement flexibility or who require European-origin documentation for subsidy eligibility. AIKO, by contrast, has concentrated its entire portfolio on its proprietary ABC (All Back Contact) n-type crystalline silicon technology, which routes all electrical contacts to the rear of the cell to maximize active light-gathering surface. The result is consistently top-ranked module efficiency in mass production - AIKO has led TaiyangNews' commercially available high-efficiency module ranking continuously since March 2023 and took first place in the 2025 SolarQuotes Installers' Choice Awards.
For a buyer focused on squeezing maximum output from a constrained residential rooftop, AIKO is the stronger default in 2025, supported by independent efficiency rankings, strong installer feedback, and a credible 30-year performance warranty. Exiom is the more relevant pick for buyers where European provenance, multi-technology access, or Iberdrola-backed domestic supply chains carry procurement weight. The two brands occupy overlapping but distinct niches and are not simply interchangeable.
