“…According to the simulation results, it is calculated that the annual electricity generation per kWp will be 1,336.6 kWh/kWp. When the environmental analysis is performed, this utilization can save 63,727.05 tons of CO2, 1.89 tons of CH4, 0.27 tons of N2O, 970.05 tons of SO2, and 590.12 tons of NO emissions in 25 years if the PV system is applied [13].…”

The use of electrical energy from renewable energy sources has increased considerably in recent years. Photovoltaic (PV) solar energy, which is one of the renewable energy sources, takes its source from the sun, which is considered an unlimited source. With the widespread use of photovoltaic systems, some legal regulations by governments have been made for their installation. Simulation programs are used for the design, layout, technical and economic analysis of PV systems. In this study, the design was made using the PVsyst, PV*SOL, Solarius programs, and the PVGIS website used in PV systems. The projects are designed to have an output power of 25 kW. According to the simulation results, the PVGIS website provides approximate data, since technical details cannot be entered. In the results of PVGIS and all simulation programs, it has been calculated that the system can produce 42-48 MWh of electrical energy annually. Power Ratio (PR) results of the system were in the range of 78-85%. Annual electrical energy production per installed kW has been calculated to be 1436-1635 kWh/year. It is stated that the annual saved CO2 will be 18.66-22.226 tons /year. When the simulation results are analyzed monthly, the differences between the months are remarkable. The reason for these deviations can be explained by the annual solar radiation (kWh/m2) data and databases used by the programs. It has been observed that the simulation programs consider the monthly average temperatures and sunshine durations of the region. It is thought that there is a need to compare real-time data with simulation results in future studies. It is considered that this study will be helpful for future studies.

Solar energy is considered as one of the clean and sustainable energy sources. As known, big portion of the energy demand in industrial processes are generally met by fossil energy sources. Utilizing renewable and sustainable energy technologies in industrial facilities can decrease negative environmental effects. In this study, applicability of a rooftop solar energy generation system in an industrial building has been analyzed. In the simulation process, PvSOL software has been employed. Considering available areas on the roof of the facility, solar electrical energy generation system with installed power of 573.75 kWp was planned and simulated. Moreover, economic analysis results of the proposed rooftop solar energy system were presented within the scope of this research. According to the economic analysis outcomes, payback period of the proposed rooftop energy system was achieved less than 4 years.
