In this paper, we evaluate the solar potential of Burkina Faso by a numerical simulation based on four theoretical models most used in the literature. We validate the numerical results obtained using the solar radiation values recorded on the meteorological sites installed in the different zones defined from the determined climatic zoning that we realized. Climate zoning is established using correlations linking air temperature, relative humidity, sunstroke duration, and global solar radiation. It appears that the territory of Burkina Faso is divided into three climatic zones. A comparative study of the results obtained by simulation from the four models and those measured has shown that whatever the climatic zone considered, the model proposed by Ball & Atwater and that of Bird & Hulstrom make it possible to better evaluate the solar potential. The results obtained with these two models for the three climatic zones come close to real values with great precision.
