Measurement and analysis programme within the Thousand Roofs Programme

The BMFT and the State governments jointly started a "Thousand Roofs Programme" in September 1990. At first, this programme was limited to the territory of the former West Germany. In July 1991, the extension to the new Federal States was announced. In the programme the installation of 2250 small (1-5 kWp) grid-connected PV systems on the roofs of one or two-family houses is being sponsored. Federal and State grants were provided for the actual system costs to an upper limit of DM 27000 per kWp. The grant proportion was 70%, 50% of the system costs from Federal and 20% from State funds.
