The implementation of renewable energy sources plays a crucial role in increasing the energy efficiency of buildings. However the evaluation of the possibility to directly use or store the gains within the building or sell the gains to a public grid is tricky, as these concepts depend on the energy demand of the building and the climate of the location considerably. Besides mere financial considerations, the ability to use or store PV energy within the building is also relevant for the future energy supply, when the energy storage within buildings will and the prices and funding for selling PV electricity or own use vary greatly from country to country. This tool helps to assess PV self-consumption potential of a building, the possibility to improve the self-consumption ratio by temporary storing PV electricity within a building, and supports to evaluate the economic potential of selling PV to the grid. It allows the user to receive information to which extend RES implementation makes sense to supply the building with energy, and) if the revenues of the PV electricity either saved or sold to the grid can compensate or exceed the investment costs.
