The federal government provides one-off payments and the floating market premium to promote the use of photovoltaic (PV) systems. There is a one-off payment for small installations (up to a capacity of 100kW) and a one-off payment for large installations (from 100kW) which covers a maximum of 30% of the investment costs of reference systems. For PV installations that feed all generated electricity into the grid, both the floating market premium (from 150kW) and a high one-off payment of up to 60% of the costs of reference systems are available. In the case of installations that produce 150kW or more, the one-off payment and floating market premium are awarded in separate auctions.
Information on the application procedure is available on the Pronovo website.
