Promotion of Thermal Solar Systems for the Generation of Process Heat

The funding of thermal solar systems for the generation of process heat in North Rhine-Westphalia supports the installation and expansion of certified solar collector systems for commercial and industrial purposes. With a fixed amount of €90 per m² gross collector area – up to a maximum of €90,000 – innovative climate protection and efficiency projects are promoted. Applicants from companies, public institutions, non-profit organizations, and private individuals benefit from continuously available funds until the guideline expires on June 30, 2027. The Arnsberg District Government, as the funding authority, guarantees a digital application process and combines the energy and climate protection expertise of the state funding agency as a modern service provider.

A prerequisite for the grant is a solar system with the European certification mark Solar Keymark, a collector area between 20 and 1,000 m², and an annual energy yield of at least 525 kWh per m², measured by a heat meter. Eligible expenses include the construction and expansion of thermal solar systems. The digital procedure begins with a cost estimate and the completed funding application, followed by automatic confirmation of receipt, approval, and subsequent payment request including proof of use. Compliance with the guideline and timely submission of the application secure the entitlement of eligible applicants. Detailed information on funding conditions and required documentation can be found in the funding guideline progres.nrw – Climate Protection Technology.
