The arrangement of modules of a photovoltaic generator "PVG" depends largely on the application. The number of modules in series in a branch and the number of branches are linked to the output voltage and current required. For a fixed number of photovoltaic modules, the maximum power is constant whatever is the configuration adopted. The operating power is dependent on the device working conditions such as the insulation, the temperature, and the load. The work presented in this article is focused on the determination of the optimal configuration of the PVG, given a fixed number of modules. Our aim is to extract the highest power of the direct coupling between the PVG and the load. In this paper, we present a new method, which consists of determining on line and in real time which configuration is best whatever is the load and the working conditions and switch the PVG into that configuration. The presented method is based on the use of the data processor. Some parameters describing PV modules have been stocked on EPROM. Very simple calculations allowed to decide which configuration is appropriate for the load whatever the work conditions. This method is particulary appropriate for all direct coupling between a PVG and a load especially for the pumping system. Results that have been obtained experimentally confirm our theoretical analysis.
