• The goal of this research is to provide a detailed overview of macroscopic and microscopic factors influencing soiling. This includes a global analysis of key parameters including dust characteristics (size of dust grains, size distribution), and particle deposition rates. The results of outdoor experiments show a negative proportionality relationship between the dust rate and the normalized PV power with a drop of up to 40% for 20 g of dust compared to the performance of the reference PV panel which has been cleaned regularly. Our results indicate that the total transmission decreases linearly in an approximately way as a function of the mass of dust and size deposited per unit area, with the slope being highly sensitive to the absorptivity of the dust. Overall, the study aims to provide a useful, in-depth but also global overview and fundamental understanding of soiling processes on PV modules, which could be used to develop appropriate soiling mitigation strategies. For this, adapted and new experimental is set and comprised: two monocrislline PV modules, two temperature sensors and two digital multimeters.
