Influence of dust deposition on photovoltaic (PV) module performance at the different sites

This research paper has been designed to investigate the effect of small dust pollutants on a solar photovoltaic panel output power capacity under different environmental conditions. The impact of the various dust pollutants on photovoltaic (PV) modules has been assessed and analyzed. The results show how dust accumulation influences the PV module's performance through output power. The panel performance gradually decreases with increasing dust accumulation on PV glass plate. Consequently, A significant amount of power loss (12.52% - 16.29%) has been recorded at the different PV sites. In which, a maximum level of power loss (16.29%) was obtained for the lime-stone site.
