Impact of dust accumulation on PV panel performance in the Saharan region

In this work, we present modeling the dust effect on the monocrystalline silicon Photovoltaic Panel (Sharp NT-R5E3E175W) in Saharan region (Adrar, Algeria) the model can be used to develop a simulation program. Its principle is based on the self-consistent iterative numerical solution of the Poisson and continuity and the transport equations. The discretization method used is that of finite differences. The parameters characterizing the solar cell such as short-circuit current, open-circuit voltage, fill factor, efficiency will be deducted from the simulated current-voltage characteristics. To validate the effectiveness of this numerical model, we will compare the simulation results with experimental measurements. Sufficient agreement was observed when we compared the experimental results of the photovoltaic panel.
