## Summary

Q-Cells, originally founded in 1999 in Germany and acquired by South Korean industrial conglomerate Hanwha Group in 2012, is one of the most recognized solar panel brands globally. Operating as Hanwha Q CELLS, the company holds BloombergNEF Tier 1 bankability status and produces modules at a scale measured in multiple gigawatts annually, with its U.S. facilities in Dalton and Cartersville, Georgia alone representing one of the largest solar manufacturing footprints in the Western Hemisphere. Selfa, by contrast, is a Polish manufacturer with roots going back to 1932 as an electrical and heating products company, entering photovoltaics in 2004 and launching an automated module production line in 2012. Selfa holds European certifications from VDE and KIWA Cermet Italia but does not appear on BloombergNEF Tier 1 lists, reflecting its considerably smaller regional scale. On institutional footprint and global bankability, Q-Cells holds a decisive advantage.

Q-Cells serves residential, commercial, and utility-scale customers through product families including the Q.PEAK DUO and Q.TRON series, with the Q.PEAK DUO line built on proprietary Q.ANTUM DUO Z cell technology incorporating TOPCon. Panel efficiencies in the Q.PEAK DUO range reach up to roughly 22.5% according to independent review sources, and the company backs its modules with 25-year product warranties. Selfa focuses primarily on the Polish and Central European residential and light commercial market, offering standard and premium monocrystalline modules with the PREMIUM series reaching 550W output, and a proprietary SELF-C self-cleaning surface coating. Independent efficiency benchmarks and confirmed cell technology details for Selfa's current lineup were not surfaced by available review sources.

For most buyers outside Central Europe - particularly those undertaking commercial or utility-scale projects where long-term warranty enforcement and financial backing are priorities - Q-Cells is the clearer default choice. Selfa represents a credible option for Polish residential buyers who value proximity to a local manufacturer and domestic service infrastructure, but it is not a direct substitute where bankability or independently benchmarked performance data are required.
