As energy supply and demand are unevenly distributed on the planet, it is necessary to find another solution to take over. It is now a question of using a cheap and economical source of energy because the protection of the environment has become an important issue. In this regard, renewables energies such as solar energy (sun), wind (wind) or hydraulic (water), geothermal (the heat of the earth's subsoil) considered as inexhaustible and easily exploitable energies appear as a solution to solve the problem. In Cameroon, for example, in the context of the use of solar energy and the opening up of energy in rural areas, the government has set up the electrification program of 1000 localities with solar photovoltaic system. The objective of this study was to identify through GIS and multi-criteria analysis, the suitable sites dedicated to the implementation of solar power stations in the Bélabo council in eastern Cameroon. The methodology consisted in the identification of the criteria (factors and constraints), in the classification and standardization of these criteria, and in their aggregation for the identification of suitable sites. This study has shown that 9% of the total area of Bélabo council has a high potential to be optimal areas for the installation of solar photovoltaic stations.
