Solar potential (2019) - Roof panels

The suitability of the roof panels for the use of solar energy for electricity generation or for hot water treatment is presented.
The database contains information on the usable solar total irradiation, shape, orientation and inclination of the roof part area as well as the maximum module area and performance of the photovoltaic system.
In addition, the information on monument protection is listed in order to point out the possible limited use of the solar potential. In accordance with § 12(2) SächsDSchG, permits under monument law for solar installations are also required for measures in monument protection areas pursuant to § 21 SächsDSchG and in the vicinity of monuments.

The basis is a modelling of solar radiation for the state capital Dresden, which was developed by the IÖR and the Chair of Geoinformatics of the Technical University of Munich (TUM) as part of the research project "Standard GDPV".
Based on the virtual 3D city model Dresden from 2019 with 135.583 buildings, the solar radiation on all roofs and facades of the state capital was calculated taking into account the shading by surrounding buildings, the urban tree population and the topography.
