## Summary

Selfa is a Polish manufacturer with roots going back to 1932, when it was established as a producer of electric heating elements near Torun. It entered photovoltaics in 2004 and launched an automated module production line in 2012, remaining a fully Polish-owned company. No BloombergNEF Tier 1 listing for Selfa appears in publicly available sources, and annual production volume is not disclosed at scale, suggesting a regional rather than global industrial footprint. AIKO, founded in 2009 and headquartered in Shanghai, reports roughly 20 GW of production capacity as of early 2025, operates six manufacturing plants and three R&D centers across China and Europe, and employs more than 15,000 people. AIKO achieved BloombergNEF Tier 1 status in Q3 2024, confirming bankability for internationally financed projects. By institutional scale and market reach, AIKO holds the decisively stronger footprint.

Selfa's product line centers on monocrystalline modules using PERC and TOPCon cell technologies, covering power classes from roughly 410 Wp to 550 Wp. The brand is oriented toward residential and small commercial rooftops in Central and Eastern Europe, backed by European certifications from VDE and KIWA Cermet Italia. AIKO has built its identity around a proprietary N-type ABC (All Back Contact) architecture. Its Comet series posted a verified mass-production module efficiency of 25.2% at Intersolar Munich 2024, and the newer INFINITE bifacial line exceeds 25% - figures that represent the leading edge of commercially available panels. AIKO targets premium residential rooftops where space efficiency is at a premium, as well as competitive commercial installations; it won the 2025 SolarQuotes Installers' Choice Awards ahead of REC and JinkoSolar.

For most buyers outside Central and Eastern Europe, AIKO is the stronger default in 2025: Tier 1 bankability, an industry-leading efficiency record, and a 30-year performance warranty make it a credible premium option. Selfa is a reasonable choice for Polish or regional buyers who value locally manufactured modules and nearby after-sales support, but it cannot match AIKO's technological depth or global track record. These are not interchangeable brands - they serve distinct buyer profiles.
