Joulee

About

Founded in 2020, Joulee is a private headquartered in Berlin, Germany with approximately 50-200 employees specializing in Solar.

Joulee Tech GmbH was founded in 2020 to address the complexity and bureaucratic burden of applying for German government energy efficiency subsidies. The company serves contractors and property owners by digitizing and streamlining the process for BAFA (Federal Office for Economic Affairs and Export Control) and KfW (KfW Development Bank) grant applications. Services include preparation of individual energy retrofit plans (iSFP), BEG (Building Energy Act) single-measure applications, and comprehensive grant application handling. Joulee has facilitated over 3,500 approved grant applications, helping customers secure more than 20 million euros in subsidies. The company employs energy efficiency experts and subject matter specialists to ensure applications meet all technical requirements and are processed quickly—typically within 5 business days. Services cover renovations including windows, doors, roof insulation, facade insulation, heating systems (heat pumps, pellet heaters), solar thermal systems, smart home technology, and lighting upgrades. Joulee operates on a fixed-price model with payment due only after the application is submitted, emphasizing transparency and reliability for partner contractors.
