Abstract
The application of the European Solar Radiation Atlas (ESRA) in daily Sun motion in sky analysis and its effects is widely spread in all engineering professions. Mathematical relations for Sun azimuth and height in specified moment, defined by date and time, can, for instance, be used in electrical engineering calculations of energy production and control of photovoltaic plants. The results obtained at measuring stations across Europe produce empirical relations between irradiation, time and electrical energy production. In this research a model of ostensible Sun movement trough daily analysis of its height and azimuth, and the analysis of production of integrated photovoltaic plant on the roof of the Technical College in Bjelovar with the web interface implementation of ESRA model for specified application – PVGIS (Photovoltaic Geographical Information Systems) are presented.
