Optimization of solar photovoltaic efficiency using angular inclination: Effect of dust deposition on PV Module

Abstract

The West African belt is known for Sahara dust influx that is a great concern as it increases the aerosol loading over the region. In this study, we examine the effect of dust deposition on solar photovoltaic (PV) panels. A local logger was constructed to determine the dust deposition and its corresponding current generation in a PV panel. The PV panel were placed at different inclination i.e. ranging from 0° to 45 ° It was observed that at 45 ° the dust deposition was higher than other PV angle inclination because the PV surface was exposed to both horizontal and vertical dust deposition.
