This work focuses on modeling the impact of desert aerosols on a mini central solar photovoltaic (PV). Our studied physical model is comparable to a multilayer. We have described and discretized the mathematical equations which govern the physical model. Also, we analyzed the influence of the parameters τa and X on the solar radiation received at the surface of solar PV modules. The results of the study taken from Figures 6(a)-(d) representing the variations of the global solar radiation on the solstices and equinoxes as well as the 21 of the months of the year days understood show that: if τ a = 0 and X = 0 , IC = 67.87% ; if τ a = 0.5 and X = 0.5 , IC = 21% ; if τ a = 0.8 and X = 0.8 , IC = 12% and if τ a = 1.5 and X = 1.5 then IC = 4% . These results show that desert aerosols significantly influence the global solar radiation received. Unfortunately, this influence lowers the productivity of the central solar PV in general.
