Der Solarservice Bremen – ein Web-GIS-basierter Informationsservice für Solarenergie in der Stadt Bremen

Abstract

Germany uses the biggest share of solar energy worldwide and could record the strongest increase in photovoltaic plants in the last few years [EPIA, 2010]. But the benefits, that are possible to gain with solar energy in this country, are still not reached by far yet. Over the half of the power requirement of the Federal Republic could be gained on the basis of a consistent use of existing roof areas [BSW, 2011]. Although on average there is less intensity of solar radiation in the north than in southern regions, the annual incident solar radiation in Bremen can go up to 950 kWh/m2. This increases the importance to use solar energy even in private households. A GIS-based information service for solar power for the city of Bremen is therefore developed by the University of Applied Sciences Bremen in cooperation with the BUND LV Bremen and the GeoInformation Bremen. The Solarservice Bremen is planned in addition to a number of information services of Bremen, which inform about solar energy, and shall increase or at least arouse the interest in solar energy for the promotion of the use of renewable energies.
