The photovoltaic self-consumption calculator provides information for a planned photovoltaic system on how and to what extent the self-consumption share of the on-site produced PV electricity can be increased. It can be used to evaluate the case of a photovoltaic system without participation in a renewable energy community. The tool can also help to calculate the increase of the self-consumption share of a system with a maximum of 10 kWp or of a household with a maximum of 10,000 kWh of annual electricity consumption through electric load management, storage, and electric water heating. The use of a heat pump and an electric car are only described qualitatively in the tool and are not included in the calculation.
