This paper presents the results of an experimental study of a PV/diesel hybrid system without storage. The results obtained show that the sizing of a PV/diesel hybrid system, by taking into account the solar radiation and the load/demand profile of a typical area, must permit the diesel generator to operate near its optimal point (70–90% of its nominal power). It has been verified that the reliability of the system necessitates that the diesel generator be sized to meet the peak-load demand in case of transient cloud and in the evening. Also, a comparative analysis for three different systems (diesel and solar PV generators only, and hybrid solar PV/diesel system) for powering a same load profile has been made and shows that the hybrid system is more cost-efficient than the two others. These results show that there is a possibility to increase the electrification rate in remote areas by the implementation of hybrid solar PV/diesel systems.

Indeed, more than 70% of the populations of this region are excluded from the benefits linked to the electricity. The situation is more catastrophic in
