Experimental Investigation of Dust Effect on PV Module Performance
The increasing of energy demand and present climate change are forcing the world energy consumers for looking towards the sustainable and environmentally friendly energy source, such as solar photovoltaic (PV). The performance PV system is primarily dictated by its surrounding environmental parameters, such as dust, temperature, solar radiation and humidity. The deposition of dust on PV module surface procreates less impact on an open circuit voltage whereas it procreates significant impacts on the short circuit current (ISC) and maximum power output (PMAX) of PV module. The present study persuades that the reduction of ISC and PMAX of PV module are 33.33% and 42%, respectively with the deposition of 12gm dust on the module surface. The results of this study demonstrated that the presence of dust particles on the module surface degrades its performance. The rate of performance degradation strongly depends on the mass of deposited dust particles on the module surface and its type.
