Since July 12 2010 the BAFA restarted subsidizing solar thermal and biomass plants as part of their market stimulus program via a new guideline.

The basic subsidiary for solar thermal systems now amounts to 90,- €/m² (45,- €/m² if the system is expanded). Liable for subsidiaries are solar collector systems up to 20 m² gross collector area for a combination of hot water generation and heating support or for process heat generation. Systems for combined hot water generation and heating support have to have a minimum gross collector area of 9 m² (7 m² with AS-CPC and AS-EVK) and a minimum storage volume of 40 liters (50 liters) per m² gross collector area. Collector systems that only serve for hot water generation as well as systems in newly erected buildings receive no more subsidiaries. Applications need to be filed after the system commissioning.
