Galaxy Energy GmbH

What Galaxy Energy GmbH does

Galaxy Energy GmbH is a privately held, family-owned German manufacturer of Building-Integrated Photovoltaics (BIPV), headquartered in Berghülen, Baden-Württemberg. Founded in 1992 and reorganized as a GmbH in 2005, the company designs and produces its proprietary Indachsystem — an in-roof BIPV architecture in which photovoltaic modules replace conventional roof coverings entirely, backed by a 20-year weather-tightness guarantee when installed by certified Fachinstallateure. The portfolio spans 13 BIPV application categories (balcony, bikeport, carport, terrace, facade, industrial buildings, parking garages, horse stables, agricultural stables, new construction, renovation, and BIPV canopies such as Casibo), plus proprietary glass-glass GG-Modulserie modules with bifacial half-cut TopCon cells, SolarEdge and Victron inverters, own-brand storage systems and Tesla Powerwall products, EV charging stations, and mounting hardware including the Quick Click ground-mount system.

The company operates a hybrid go-to-market model: a German channel of 221 partner firms and 550 certified BIPV specialist installers handles most projects, supplemented by direct enterprise field sales for large or architect-led projects and a login-gated online shop selling 364 SKUs of modules, mounting profiles, sealing systems, insulation, inverters, storage, and accessories to registered tradespeople. Certified installer training (BIPV and Speicher Fachinstallateur, 120 EUR per day) is both a revenue stream and a quality control mechanism that conditions the guarantee. Customers span residential, commercial, industrial, agricultural, and public-sector segments across at least 17 countries. Galaxy Energy holds a dense certification stack (TÜV Rheinland IEC 61215/61730, DIN EN ISO 9001/14001, BRoof(t1), DLG ammonia resistance, JETPVm, HypoVereinsbank bankability) and a US BIPV patent. The company is bootstrapped, with no disclosed external funding, and is led by the second generation of the Schöll family following a 2018 leadership transition from founder Georg Schöll.
