Structural and physical properties of the dust particles in Qatar and their influence on the PV panel performance by Brahim Aïssa (14157243)

“…The installation of PV systems aimed at optimizing solar energy yield is primarily dictated by its geographic location and installation design to maximize solar exposure. However, even when these characteristics have been addressed appropriately, there are other factors that adversely affect the performance of PV systems, namely the temperature-induced voltage decrease leading to a PV power loss and the dust accumulation (soiling). …”
