In this paper,a detailed model of a photovoltaic(PV)panel is used to study the accumulation of dust on solar *** presence of dust diminishes the incident light intensity penetrating the panel’s cover glass,as it increases the reflection of light by *** phenomenon,commonly known as the“soiling effect”,presents a significant challenge to PV systems on a global *** basic models of the equivalent circuits of a solar cell can be found,namely the single-diode model and the two-diode *** limitation of efficiency data in manufacturers’datasheets has encouraged us to develop an equivalent electrical model that is efficient under dust conditions,integrated with optical transmittance considerations to investigate the soiling *** proposed approach is based on the use of experimental current-voltage(I-V)characteristics with simulated data using MATLAB/*** research outcomes underscores the feasibility of accurately quantifying the reduction in energy production resulting from soiling by assessing the optical transmittance of accumulated dust on the surface of PV glass.
