This work presents an experimental study to utilize extreme sun rays temperature via Fresnel’s lens concentrate using a solar tracking system. The experimental rig consists of a freely rotating two-axis frame that is controlled by an electronic circuit that implements Arduino and stepper motors as a control system to adjust the position of the Fresnel’s lens focal by moving the motors accordingly. The focal of the sunray is to be maintained stationary at a fixed position to ensure continuity of heat flow on the absorption plate. The experimental results showed that the focal temperature reached as high as 422° C when the ambient temperature was 17° C. Observing the results, gives an idea of promising ability to use the Fresnel’s lens in a wide range of renewable energy applications such as heating and heat storage.
