This paper describes a variety of analytical and numerical approaches are proposed for the solution of inverse problems in heat transfer of solar radiation effect. As we know about solar radiation give to make effects negative and positive in life. This research will analyze heat transfer function and simulate that function to solar radiation. This work proposes a transfer function identification method to solve inverse heat radiation problems. The technique is based on Green’s function and the equivalence between thermal and dynamic systems. The result will simulate used MATLAB and COMSOL software. Assuming no cloud cover, the solar flux at the surface is about 1000 W/m2. All of the ambient surfaces of the model are included in the solar loading calculation, and shadowing effects are included. The temperature of the sun is about 5800 K, and it emits primarily short-wavelength infrared and visible light at wavelengths shorter than 2.5 microns.
