In this paper, an approach consisting in moving photovoltaic panels according to the maximum sunshine position in order to extract a high efficiency is proposed. Firstly, the model of the photovoltaic generator is described. Secondly the designed maximum sunshine position tracking system is presented and experimental results consisting of no-load voltage variations during different periods of the year are described. Finally, a comparison study between three direct torque control (DTC) strategies dedicated for the maximum sunshine position tracking system is carried out. It has been found that the three DTC strategies exhibit high dynamic performance. However, these strategies are more or less penalized by some drawbacks such as demagnetization, high commutation frequency and high torque ripples.
