Solar flux pattern is generated at different beam incident angles using Equation (4). Odeh et al reported that solar flux decreases as one moves away from the receiver centre [6]. The deviation of the beam incident angle from the normal produces a significant reduction in solar flux and an increase in the maximum width of the solar image. Based on that, Odeh et al concluded that the receiver width must be around 6 cm to intercept all solar images during low solar elevation angle hours [6]. The receiver unit consists of a copper tube 2 m long, with a diameter of 2 cm that is fixed on a 6 cm
