Modeling the Impact of Desert Aerosols on the Solar Radiation of a Mini Solar Central Photovoltaic (PV)

摘要

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 τ_a 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, I_c = 67.87%; if τ_a=0.5 and X = 0.5,I_c=21%;if τ_a=0.8 and X = 0.8, I_c=12% and if τ_a=1.5 and X= 1.5 then I_c= 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.
