The irradiation intensity is the primary catalyst for energy production in photovoltaic (PV) systems. Nevertheless, it alleviates partial shading (PS) by inhibiting power production, primarily habitable metropolitan areas, owing to surrounding objects or high soiling rates, particularly dry and semi-arid climates. Hence, PV module's location, orientation, tilt angle significantly affect its performance shorten durability. Thus, this study undertakes a benchmark analysis of two distinct panel...
