Rising energy costs and environmental problems, also the limited resources of fossil fuels, have forced humans to use renewable energy. One of the systems that are commonly used is the cooling system, by means of solar energy. Since these models have a wide variety of effective variables, such as the temperature, latitude, the length of the day, also due to the nonlinear relationship between the variables, conventional modeling methods are inefficient. Therefore regarding to the extensive capabilities of simulation models in modeling a wide range of variables with complex and nonlinear relationship, in this study with the approach of simulating solar systems, an effective survey in the field of economic and efficiency of such systems, is presented.
