Utilizing solar power to generate thermal energy is an effective method for realizing grid-scale dispatchable power generation and replacing conventional energy, which may bring revolutionary solutions to serious energy problems ( Romero et al., 2002, Behar et al., 2013 ).
With the evacuated tube solar heating system, 50 TEG modules were installed around the heat exchanger, the main heat supply for space heating. As shown in Fig. 1, the hot side of the TEG is contacted perfectly on the outer surface of the heat exchanger while the cold one is in direct contact with the surrounding space air to be heated.
The actual heat tube is arranged in a cylindrical receiver. The solar radiation energy received by the heat tube is non-uniform, with a circumference that is half heated and half adiabatic. One side of the tube called the heating surface receives heat flux from the solar radiation, whereas the adiabatic side is covered with a heat insulator.
