Abstract

Solar energy is a type of 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 200 kW on-grid power plant was demonstrated by PVsyst software, and 364 modules (550 W) were used on the rooftop in Shiraz. Considering the geographical location of Shiraz, which is located at a latitude of 29.82 N and longitude of 52.60 E, and considering shading and the maximum use of sunlight, an angle of 30° is suitable for installing solar panels. The results showed that the total energy received by the panels is equal to 480.4 MW/h per year; after deducting the system losses, the amount of energy injected into the national grid will be equal to 413.2 MW/h per year. The annual global irradiance on the horizontal plane is 2199.1 kWh/m2, while the global incident in the collector plane and effective global irradiance after optical losses are 2467.3 kWh/m2 and 2396 kWh/m2, respectively. The annual DC energy produced from the PV array and the annual AC energy injected into the grid are 427.81 and 413.2 MWh, respectively. The cumulative cash flow rate showed that after 20 years, the income of this power plant was 7000 billion IRR.
