Abstract: A comprehensive theoretical model is proposed for the performance evaluation of a solar chimney power plant (SCPP), and has been verified by the experimental data of the Spanish prototype. This model takes account of the effects of flow and heat losses, and the temperature lapse rates inside and outside the chimney. There is a maximum power output for a certain SCPP under a given solar radiation condition, due to flow and heat losses and the installation of the turbines. In addition, the design flow rate of the turbine in the SCPP system is found beneficial for power output when it is lower than that at the maximum power point. Furthermore, a limitation on the maximum collector radius exists for the maximum attainable power of the SCPP; whereas, no such limitation exists for chimney height in terms of contemporary construction technology.
