Solar chimney power plant (SCPP) is among the potential technologies in all over the world. In this study, a comprehensive energy and exergy analysis has been performed for SCPP. Exergy balance of the SCPP is conducted to calculate the irreversibility and exergetic efficiency of the SCPP. Influence of the effective parameters e.g. tower height, solar radiation, tower and collector radius is examined on the performance of the SCPP through the parametric study. The results show that by increasing all the effective parameters, irreversibility would increase except for tower radius. The results further indicate by increasing the collector radius, there is a maximum point from exergetic efficiency viewpoint. Eventually, increment of the effective parameters would increase the power output.
