Abstract
This paper deals with the design of photovoltaic (PV) systems in the roof plane of a parking garage for passenger cars. The selected type of PV system is optimized in terms of maximum efficiency of electricity production. A model solution for a parking house is being located on the outskirts of Žilina. The facade and roof of the parking house is without external shading by the surrounding buildings and vegetation. PV technology is located on the flat roof of the garage house. The optimization of the layout and inclination of the photovoltaic panels was performed in several variants. The energy produced is stored in batteries, which are located in the engine room. It is situated on the roof of the garage house above the charging stations of passenger cars, which are at the level of the 1st floor. In terms of economic efficiency, the optimal solution of PV technology from the analyzed variants for the climatic conditions of the Žilina locality was assessed. By economic analysis, we found that by installing PV panels, we can ensure the production of electricity for 6 charging stations and cover energy consumption related to the operation of the building.
