Written summary
Corab is a Polish company founded in 1991 and headquartered in Olsztyn, with manufacturing in Bartoszyce, Poland. It built its reputation as a maker of steel and aluminum photovoltaic mounting structures and has since expanded into distributing full PV systems - including its own Encor-branded solar modules - across more than 30 European countries. Acquired by MS Galleon in late 2024, Corab has no confirmed BloombergNEF Tier 1 bankability classification for its own panel line. AIKO, by contrast, is a Chinese manufacturer founded in 2009 that achieved BloombergNEF Tier 1 status in Q3 2024 and reports approximately 20 GW of annual production capacity. On institutional footprint - bank financing, independent certification, and global project volume - AIKO holds a clear advantage.
Corab's own-brand Encor modules are positioned as mid-range commercial and residential products for the Central and Eastern European market, backed by a 12-year product warranty and a 25-year linear performance warranty. The company's stronger suit remains its mounting hardware and full-system integration, rather than panel innovation. AIKO's product identity is built around its proprietary ABC (All Back Contact) cell technology - an n-type architecture distinct from standard TOPCon or HJT - which the company has driven to a confirmed commercial production efficiency of 24.8%, with a world-record module efficiency of 25.2% demonstrated at Intersolar Munich in 2024. Its residential and commercial-and-industrial series have earned a spot on the 2024 PV Evolution Labs Top Performers list and won the 2025 SolarQuotes Installers' Choice Award in Australia.
For most buyers evaluating panels on efficiency, warranty depth, bankability, and third-party validation, AIKO is the stronger default choice in 2025. Corab remains a credible regional option - particularly for buyers who value European manufacturing, tight supply-chain integration with mounting hardware, or proximity for after-sales support in Central Europe - but it cannot match AIKO's technology credentials or global institutional standing.
