Abstract: The research involved verifying the effect of solar radiation on the heat transfer process of a solar radiation simulator through a regulator designed to change the radiation intensity of a halogen type (9) that was used as simulation instead of sunlight with three rates (500, 800, 1100 W/m2). Three flow rates (1, 1.5, 2 L/min) were also used within the flux. The experiments were conducted in Karbala, Iraq with a latitude 32.60 North. Five angles of the solar complex were used for each test inside a closed room. The results showed that the maximum temperature difference between the input and exit of water during the solar complex is 10.8°C obtained at a flow rate 1 L/min, radiation rate 1100 W/m2 and angle 22° the numerical simulation program ANSYS was also used to solve the numerical side and the numerical results of the exit temperature of the solar collector system showed reasonable agreement with the practical results. Where it was found that the maximum percentage of error between the results of the process and the numerical was 5%.
