Utilizing reliable monitoring and available data in order to ensure that the PV plants become bestreturn-on investments is possible thanks to ever going developments in data-driven algorithms. One of the major challenges in PV power generation is the soiling events caused by the dusty environments and climatic conditions resulting in the reduction of the performance of the PV plants. Since the soiling is a complex event whose characteristics are forged by a number of external stochastic phenomena, a number of studies are conducted by researchers. Soiling in PV plants is a continuous subject that emerges over time as an important drawback in the performance of the PV plants. In that point, it is crucial to automatically determine appropriate cleaning schedules in order to achieve a high-profit PV plant operation. In this study, a method is presented which only uses the DC current inputs of the inverters to determine the soiling loss without using any environmental sensors. The proposed method is tested by conducting experimental works on three different PV plants which are connected to the power grid in Turkey. The results show that the proposed method is effective for analyzing the performance reductions due to soiling in the PV plants without using any environmental sensors.
