Photogrammetric estimation of shading impacts on photovoltaic systems

In order to decide the place to install a PV system and to estimate its performance, it is important to consider the effect of shadows on the PV array before and after PV system comes into operation. However, the shading effect cannot be evaluated easily on site because the position of obstacles surrounding the PV system is difficult to specify. Therefore, this paper is intended to develop new software for estimating the position of obstacles and their shadow by using the triangulation with two photographs or more.
