Global denken - lokal handeln: ein Beitrag zur lokalen Umsetzung der Energiewende durch 4-dimensionale GIS-basierte Solarpotenzialanalysen

To reach the political goals for renewable energies in Germany, further installations of photovoltaics are necessary, despite the decreasing feed-in tariffs. Roofs of private and public buildings offer large potentials. These potentials can be used without additional land consumption and the resulting impacts on nature and the environment. To inform and motivate building owners efficiently concerning the installation of rooftop photovoltaics, an insolation analysis was developed, based on high-resolution digital surface models. With its spatiotemporal high resolution of electricity production potentials and the inclusion of temporally varying self-consumption, a valid prognosis of profitability is possible.
