Unlike the classical the highest potential, solar tracking system was employed. This paper fixed PV panels, the mobile ones driven by solar trackers are shows design and realization of automatic solar panel orientation kept under optimum isolation for all positions of the Sun, system in order to achieve high performances. This can be done by keeping the solar panel at 90 degree to the sun rays. To achieve boosting thus the PV conversion efficiency of the system. The this, components like PIC microcontroller, a DC gear motor, four output energy of PV panels equipped with solar trackers may solar cells, and a gear wheel arrangement were used. The solar increase with tens of percent, especially during the summer tracking system operates by the comparison of voltages using solar when the energy harnessed from the sun is more important. cell array, which is connected to the PIC microcontroller. And so, the Photo-Voltaic or PV cells, known commonly as solar cells, main panel rotates where the maximum light is absorbed. As a result convert the energy fr
