Abstract

Experiments of soiling effects on the performances of a PV panel have been performed using dust collected from two sites in the region of Agadir-Morocco. The optical transmittance of the front glass was found to depend on the nature and density of dust. The nature of dust was studied by means of scanning electron microscopy and energy dispersive x-ray spectroscopy. It was found that the granulometry of dust particles depends on the study area. For a dust density of around 20 g/m², the maximum power Pmax of the solar panel decreases drastically from 30 to 20 W for the (HP) site, and no more than 14 W for the (AD) site. The diversity of the behavior of the soiled panel was explained in terms of the size of the particles collected from each area. The transmission of light across the front glass of the PV panel is more affected when the sizes of particles are small.
