Further development of the hybrid energy system encourages the supply of new hybrid installations, the operation of which is determined by precise design, selection of the best equipment and modeling. To assess the performance of photovoltaic systems, geographical location by coordinates, orientation of the panel by installations, climatic conditions (temperature, solar insolation, etc.) were taken into account. Using the program functions, based on the daily load schedule, the main electrical equipment of the hybrid installation was selected: charge controller, photovoltaic module, batteries, diesel generator. A 3D model of the object is constructed using a horizon graph and a shading diagram. The efficiency index shows the highest level of use of this system, thanks to solar energy and the coefficient of performance.
