What Fellow Energy does

Fellow Energy (Fellow Enerji A.Ş.) is a Turkish photovoltaic solar module and cell manufacturer founded in 2020 and headquartered in Gaziantep, Türkiye. The company operates two state-of-the-art production facilities with a fully integrated production chain spanning silicon wafer slicing, cell processing, and module assembly, making it one of the first firms in Türkiye to operate such a vertically integrated solar cell production line. Its product portfolio includes high-efficiency N-Type TOPCon and P-Type PERC solar cells (with documented cell efficiencies up to 25.70% and 23.50% respectively), a broad range of PV modules from 360W to 720W covering standard, bifacial, double-glass, and flexible lightweight formats, and the recently launched Jupiter series based on proprietary PERT Plus technology achieving over 25.2% conversion efficiency with bifaciality exceeding 80%. The PERT Plus platform was developed in partnership with ODTÜ-GÜNAM at Middle East Technical University and was officially introduced on January 16, 2026, followed by the Jupiter product launch at SolarEX Istanbul 2026 in April 2026.

The company operates a direct sales model targeting enterprise energy producers and utility-scale solar project developers, complemented by event-driven GTM via trade exhibitions. Pricing is quote-based and determined through consultation with the sales team, with no public price list. Documented enterprise customers include Turk Telekom (52 MW project commissioned November 2025, financed by Akbank T.A.Ş.) and Hoshaber DGES (35 MW project commissioned December 2025, financed by Ziraat Bankası). Fellow Energy is recognized as a BloombergNEF Tier 1 PV module maker and PVEL Top Performer, with ISO 9001/14001/45001, TÜV SÜD, and CSA certifications, and claims distribution across the Americas, Europe, the Middle East, Asia, and Africa.
