Shadow effect on Photovoltaic potentiality analysis using 3D city models.
Three dimensional city models are presently being used in many sectors. The po-tentiality of three dimensional data has been exploited by many researchers and applications. It has been realized that 3D data are not only for visualization or navigation but to support solving more complex problems in urban planning, disaster management, facility management etc. In this paper a 3D city model is used to perform a solar energy potentiality analysis. In contrast to existing methods shadowing effects on the roof surface and fa?ades are taken into account to achieve better simulation results. Of course, geometric details of the building geometry directly effect the calculation of shadows. In principle, 3D city models or point clouds, which contain roof structure, vegetation, thematically differentiated surface and texture, are suitable to simu-late exact real-time shadow. Solar radiation data during the whole day and around the year and photovoltaic cells response to the radiation can be modeled using available simulation environ-ment. However, the real impact on geometric details has to be investigated in further research.
