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

SOMI (SOMI Applications and Services s.r.o.) is a small Czech-based solar company that functions primarily as a regional panel supplier and installer rather than a vertically integrated manufacturer. It holds no documented BloombergNEF Tier 1 bankability designation, and available industry sources place it firmly in the category of a local or mid-European distribution business rather than a volume producer with global project financing behind it. AIKO Solar, by contrast, is a Chinese manufacturer founded in 2009 that achieved BloombergNEF Tier 1 status in Q3 2024, operates six production facilities in China alongside R&D centers in China and Europe, and reported a nameplate production capacity of around 20 GW as of early 2025. On institutional footprint, AIKO is significantly larger and more bankable.

SOMI's publicly documented product range covers monocrystalline and PERC bifacial modules in a mid-wattage bracket aimed at residential and small commercial rooftops in Central Europe - a sensible positioning for a regional operator serving installers in a single-country or multi-country niche. AIKO centers its entire product strategy on N-type ABC (All Back Contact) cell technology, which relocates all electrical contacts to the rear of the cell, boosting light capture and enabling module efficiencies reaching 25.2% - a world record figure demonstrated at Intersolar Munich in 2024 and confirmed by PV Magazine. The ABC line targets premium residential rooftops and space-constrained commercial installations where every square meter of generation matters, and AIKO panels earned top-performer recognition in the 2024 PV Top Performers List across multiple test categories.

For most buyers outside Central Europe seeking a bankable, high-efficiency panel in 2025, AIKO is the stronger default choice. Its Tier 1 status, demonstrable technology lead in the ABC segment, and independent third-party validation make it a defensible pick for residential projects where long-term performance and warranty security are priorities. SOMI may suit buyers who value local service relationships and supply-chain proximity within the Czech or broader Central European market, but it cannot match AIKO's documented global track record.
