Abstract: In this paper, thermodynamic analysis of a solar powered hybrid system consisting of thermoelectric generator (TEG) and organic Rankine cycle (ORC) is presented. High temperature thermic fluid (Dowtherm A), coming from parabolic solar concentrator (PSC), is used to supply heat to the hot end of TEG and to the heat recovery vapour generator (HRVG). The cold end of TEG acts as a preheater for downstream ORC, where heat is recovered by the ORC working fluid (R134a). In the base case analysis, the TEG gives a fixed power output of 500 W and accordingly its heat supply and heat rejection rates are estimated. The combined TEG-ORC system gives 7.5 kW of power at an overall efficiency of 9.75% in the base case configuration. The performance of the combined system is analysed under varying hot end temperature (HET).
