Abstract
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.
Keywords: hybrid system, photovoltaic, diesel, electrification, off-grid areas.
1 Introduction
The electrification rate in sub-Saharan Africa is lower than in any region of the
world. 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
