Dust deposition on the surface of photovoltaic (PV) modules causes significant losses in photovoltaic systems, with power drops of up to 50% in some regions. This means it can lead to large financial losses due to lower energy yield of PV systems and higher Operation & Maintenance (O&M) costs and uncertainty in PV performance. Therefore, accurately monitoring and quantifying soiling is essential to establishing an optimal cleaning schedule. The scope of this work is to present the methodology for extracting soiling losses in real time for photovoltaic (PV) systems located in different climatic conditions. This work describes several methodologies to quantify soiling losses using PV performance data, without the need for soiling stations or additional labor and maintenance costs. The applicability of the different methodologies is validated in the different localities, presenting average values extracted from soiling ratios of 0.98 for Jaén and Nicosia and 0.99 for Sidirokastro. These results explain the climatic characteristics of each location, a factor that directly affects the analysis of soiling in photovoltaic systems.
