After the mechanical control unit of the designed system was started, the performance measurements of the solar panel were carried out first when the solar panel was in a fixed position and then the solar panel was controlled while tracking the sun on azimuth and solar altitude angles and the necessary measurements were performed. It was observed that the control system operated without a problem. Besides, when the data obtained from the measurements were compared, it was seen that 42.6% more energy was obtained in the two-axes sun-tracking system when compared to the fixed system.
