This research is devoted to the energy, exergy, and economic analyses and optimization of a heliostat field. The model of the heliostat solar receiver includes detailed geometric factors related to the optical and thermal losses and efficiencies throughout the year. The main parameters of the thermal performance of this system consist of energy and exergy efficiencies, and economic parameters are investigated. By computing the energy, exergy, and economic analysis tools, they are applied for the analysis of performance, and viability of the system’s operating in Tehran City, including the detailed information of the environmental conditions of that location. For optimization purposes, 7 design variables related to geometric specification of the heliostat field are selected and the related lower and upper bonds are selected. Two target functions considered for the optimization are heliostat field exergy efficiency and payback period. The economic feasibility results of this study reveal that the net present value is 58.84 million US$, the payback period is 6.76 years, and the internal rate of return is 0.16. By considering the MOPSO algorithml, the annual mean exergy efficiency is increased from the 30.9–34.3% while the heliostat field payback period in reduced from the 6.76 to 4.3 years.
