ESTIMATION OF OBJECTS SOLAR POTENTIAL USING LIDAR DATA
KOMUNALNA ENERGETIKA / POWER ENGINERING, 18
Solar energy is an attractive resource to gain electrical energy. Although this resource is renewable and available every day, the maximum amount of incoming energy depends on various factors. In this paper, a method to calculate solar potential of the buildings roofs, for a given location and time frame is given. The proposed method considers position and orientation of Earth in respect to the Sun, inclination of objects and surfaces using detailed topography obtained from LiDAR, influence from shadowing and meteorological effects. The maximum solar energy is adjusted according to the shadowing and meteorological influence. In this way, proposed method gives a better approximation of the real world solar energy potential.

METHOD FOR ESTIMATING ROOFS SOLAR POTENTIAL CALCULATED ON LIDAR DATA
KOMUNALNA ENERGETIKA / POWER ENGINERING, 23
Buildings' roofs are becoming increasingly important for photovoltaic systems installation. They can increase efficiency of electrical usage and decrease the amount of greenhouse emissions. However, not all roofs are suitable for photovoltaic systems installation. This work proposes a method for estimating roofs’ solar potential. The solar potential is calculated on LiDAR data using measurements of direct and diffuse solar irradiance from pyranometer at a given location. Multiresolutional shadowing is proposed for achieving higher accuracy in the solar potential calculation.
