Written summary
Fellow Energy is a photovoltaic manufacturer founded in 2020 and headquartered in Gaziantep, Turkey. The company operates three factories with a reported combined capacity of around 2.1 GW per year, producing TOPCon monocrystalline and bifacial double-glass modules. It holds Tier 1 bankable status, giving it access to project finance, though it remains a younger and predominantly regional player. AIKO Solar is a Chinese manufacturer with considerably greater scale, reaching approximately 20 GW of annual production capacity as of early 2025 and earning BloombergNEF Tier 1 status as of Q3 2024. AIKO also maintains an R&D facility in Germany and distributes modules to more than 60 countries. On scale, geographic reach, and independent bankability recognition, AIKO carries the stronger institutional footprint of the two.
Fellow Energy's catalog centers on TOPCon monocrystalline modules, including bifacial double-glass variants suited to commercial rooftops and cost-sensitive ground-mount projects where reliable, bankable output is the priority. AIKO's defining product line uses its proprietary ABC (All Back Contact) cell architecture - an n-type approach that moves all electrical contacts to the rear of the cell so the entire front surface captures light without obstruction. This design has placed AIKO at or near the top of independent module efficiency rankings for multiple consecutive years, with mass-production efficiencies confirmed above 24 percent and peak figures claimed beyond 25 percent. AIKO markets ABC modules across premium residential rooftops, commercial and industrial applications, and - through a dedicated product line launched more recently - utility-scale ground mounts.
For most buyers in 2025, AIKO is the stronger default where high power density or space-constrained rooftops are the deciding factor, backed by a well-established global service network. Fellow Energy is a credible regional option for buyers in or near Turkey seeking a bankable, competitively priced TOPCon module, though the brand's shorter track record warrants due diligence on local installer availability. The two are not interchangeable: AIKO's ABC technology and global scale give it a distinct edge for demanding or premium applications.
