Cost Effective Design of a ۲۰۰ kW On-grid Rooftop Photovoltaic System Using PVsyst Software in Shiraz

Solar energy is a clean and nonrenewable energy provided by photovoltaic systems, and its use is increasing daily. In Iran, due to the diversity of the climate and the need to supply electricity on a large scale, the use of solar energy to supply the electricity needed by industrial and household units is considered. In this research, the economic design of a ۲۰۰ kW on-grid power plant was demonstrated by PVsyst software using ۳۶۴ modules (۵۵۰ W) on a rooftop in Shiraz. Taking into account the geographical location of Shiraz (which is located at a latitude of ۲۹.۸۲ N and longitude of ۵۲.۶۰ E) and shading and the maximum use of sunlight, an angle of ۳۰° was considered suitable for installing solar panels. The results showed that the total energy received by the panels was equal to ۴۸۰.۴ MW/h per year; after deducting the system losses, the amount of energy injected into the national grid was equal to ۴۱۳.۲ MW/h per year. The annual global irradiance on the horizontal plane was ۲۱۹۹.۱ kWh/m۲, while the global incident in the collector plane and effective global irradiance after optical losses were ۲۴۶۷.۳ kWh/m۲ and ۲۳۹۶ kWh/m۲, respectively. The annual DC energy produced from the PV array and the annual AC energy injected into the grid were ۴۲۷.۸۱ and ۴۱۳.۲ MWh, respectively. The cumulative cash flow rate showed that after ۲۰ years, the income of this power plant was ۷۰۰۰ billion IRR.
