**4. Solar Water Pumping System Optimization Techniques**

The optimization of the solar pumping system using an MPPT tracker is shown in Figure 5. In addition, the system structure consists of a GPV that powers the electric motor. The latter drives a centrifugal pump through an MPPT controller. Then a series of studies are carried out to give an overview of the influence of MPPT techniques on the performance of the pumping system.
