The Solar Thermal Electricity (STE) has significant capability to satisfy apart of energy demands.An integrated assessment shows that STE could play a promising role in Iran, helping to reachambitious climate safety targets. This paper is response to the urgent need to accelerate the evolutionof advanced energy technologies to refer the universal challenges of clean energy and sustainabledevelopment. The extensive aim of this paper is to exhibit the essential role of energy technologies.The two most prominent solar energy technologies are photovoltaic (PV) and concentrated solarpower (CSP). PV systems are beneficial because of their flexible size; but they are costly and solelygenerate electricity. However, to investigate PV cell performance and power generation throughoutIran, 5 different regions across the country are considered. The obtained results showed that PV cellscan generate electrical power from 155 to 385 Wh/module.day. This power generation is enough forthe requirement of the isolated regions and can even utilize to support the grid. Economic analysisbase on the payback period is included. The electricity generating costs estimation for five virtualcities in Iran shows a long-term reduction of power costs.
