Designing of Software for Determining Optimal Tilt Angle of Photovoltaic Panels

Abstract

Abstract. High anthropogenic load on the environment due to the intensive development of energy sector worldwide is forcing to seek environmentally friendly available sources of energy, for example, to utilize solar energy. To enhance the economic and environmental attractiveness of projects for the constructing solar power facilities there must be achieved maximum realization of existing solar energy potential and defined optimal placement of the receiving surface of photovoltaic panels regarding the Sun motion. The purpose of the article is to design software program of determining the optimal inclination angle of the receiving surface, taking into account solar radiation intensity falling on the differently oriented surfaces during the day to increase the level of utilizing solar energy potential in a given period of time, to reduce the computation time, increasing the effectiveness of the decisions. The proposed computer program can be used as a structural element of designing systems of microgrids, engineering facilities using solar energy modules, stand-alone and network, roof or ground-based solar power plants.
