Abstract

This paper is to develop a mathematical model for hybrid solar parabolic trough concentrator (PTC) systems. The model is for estimation of energy outputs, losses and efficiencies of various parts of the system which operates under different climate condition, diverse configurations and a range of loading conditions. Automated system optimization can be quickly obtained by trying numerous different system configurations. In hybrid PTC system, photovoltaic cells are also installed on the receiver pipes. Solar energy is directly converted to electricity by photovoltaic cells. The working fluid circulating in the receiver pipes is for solar thermal purpose as well as to cool down the temperature of solar cells. The overall yield of the system is increased and therefore capital cost is reduced. A detailed analytical model simulating a hybrid PTC system has been developed by modelling and integrating sub-components into one model and a simulation software has been developed. The software is a valuable design tools for engineers whenever they are designing hybrid PTC systems, which are likely feasible in application to densely populated city with sub-tropical climatic conditions in southern part of China. System performance has been tested with a set of initial parameters and preliminary results have been produced.
