Human health and subsistence have always been, directly and indirectly, affected by climate change events. Although the general trend of temperature in the Late Holocene has been toward cooling, due to the growing population and intense human activities over the past 150 years, the global temperature has risen. To mitigate climate change, the widespread use of renewable energy and the reduction of fossil fuel utilization are feasible solutions. The largest source of renewable energy is solar radiation, and Iran is one of the countries with high solar energy potential. In this study, technical research is done on the potential of solar photovoltaic (PV) power plant installment in Lut Desert, located in eastern Iran, to provide all electricity consumption of the country. This region receives the maximum solar radiation per year. In the proposed power plant, 305 WLG solar panels and 60 kW SMA solar inverters are applied. The modeling of this project has been done in PVsyst software with the annual temperature data of the Lut region. The results show that this project requires 140 solar PV power plants with a 1 GW capacity in an area of 2100 km2.
