The solar regulator controls the state of charge of batteries, and in the same time the energy supplied by photovoltaic panels is optimized to the maximum independently of weather. This late function is ensured by a DC/DC converter of Boost-type and a digital MPPT command based on the use of a microcontroller. The results obtained during days with weather perturbations, showed the robustness of the PV system (stability, optimal functioning of PV panels), the good control of charge of batteries under the maximum of energy supplied by the PV panels, according to three phases, determinate the state of charge and the protection against the overcharge and the deep discharge.

The disadvantage of these commands is that they are suffering from divergence problems caused by a sudden change in weather conditions (light, temperature,) or load variations. Therefore, we developed a CDCS circuit for the analog MPPT command to optimize the reliability of PV system independently of weather conditions changes or load variations. The functioning of the PV system during whole days shows a very good agreement between the experiment and the optimal simulation of the electric properties of the PV panel (voltage, current and power). The low losses of electrical energy produced by the PV panel (lower than 5 %) and the smooth functioning of the DC/DC converter used (efficiency upper to 80 %) reveal the good functioning and reliability of the systems using b both types of MPPT commands conceived and realized during this work.

We have analyzed in a deeper way the optimal operation of PV panels as a function of the weather conditions (solar irradiation, temperatures…), and design of a PV system provided with MPPT command ensuring instantaneously the optimal operation of PV panels. We have improved the structure and the operation of an analogical MPPT command (Salameh ZM et al., 1991) in order that it ensures an optimal operation independently of the weather and load variations. MPPT command chosen is characterized by its simplicity of realization and its low cost. The various results obtained show that optimal electric properties (voltage, current and power) of PV panels depend on solar irradiation and the temperature. Also, PV system optimizes the operation of PV panels independently of the number of PV panels and nature of the load (resistive, batteries…). Key...
