Impact of Desert Aerosols on the Solar Radiation of a Solar Central Photovoltaic (PV): A Modelling Approach

Abstract

This work focuses on modeling the impact of desert aerosols on a 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 \(\tau\)a and X on the solar radiation received at the surface of solar PV modules. The results of the study taken from Figs. 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 \(\tau_{a}\) = 0 and X = 0, I_C = 67.87% ; if \(\tau_{a}\) = 0.5 \(\mu\)m and X = 0.5 \(\mu\)m,  I_C = 21% ; if \(\tau_{a}\) = 1.8 \(\mu\)m and X = 0.8 \(\mu\)m, I_C = 12% and if \(\tau_{a}\) = 1.5 \(\mu\)m and X = 1.5 \(\mu\)m 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. The present study aims global to investigate the influence of desert aerosols on the production yield of the IRSAT solar central PV and characterize the aerosols impact on the production yield of the solar central PV. The specific objectives of the study are to : (i) evalute the optical depth of desert aerosols in the atmosphere above the solar central PV ; (ii) model the process of a simultaneous impact of the dust suspended in the atmosphere and / or deposited on the solar PV field ; (iii) evaluate the impact of desert aerosols (to different suspension layers and / or disposition) on incident (direct, diffuse, thoughtful and global) solar radiation and production yield of solar PV solar systems.
