SOLAR CADASTRE IN TIMISOARA, ROMANIA

The topic of the paper refers to solar cadastre regarded from the point of view of choosing the optimal areas for placing photovoltaic panels and the importance for implementing sources energy. In the scientific literature, solar cadastre is also known as roofs cadastre or potential solar cadastre. It is based on the digital terrain model and climate information available for studied areas. Analysis of solar energy and full potential of solar cadastre can be used in various fields as civil engineering or urban planning, also in the projects of research and the investment of energy sources. An important aspect of the presented study case is the decrease of the use of agricultural lands for photovoltaic parks. One way to generate renewable energy in our existing urban environment is to use the solar energy. A method for analysing the potential of existing built environment for obtaining energy sources is by creating solar maps. A solar map or a solar cadastre is a GIS that provides data about yearly solar radiation on the building's surfaces (roof and/ or facade). The current solar maps have different levels of advancement.
