Over 20% Reduction in Solar Energy Production Due to Dust

A new scientific study by the Cyprus Institute has recorded a reduction of 20% or more in solar energy production due to dust reaching photovoltaic systems in Cyprus. The research highlights that the largest losses are observed on clear days when production should be high, and that the efficiency of photovoltaic systems can decrease abruptly during dust episodes, creating problems in electricity grid management. Researchers developed a new machine learning model and analyzed data from 472 photovoltaic installations across Cyprus to accurately record when and to what extent dust affects energy production. This methodology distinguishes the effect of dust from that of clouds, providing a critical tool for energy planning. The study was conducted in collaboration with the Cyprus University of Technology and with the participation of industry partners. The findings are particularly important for Cyprus, which is investing in solar energy but is increasingly affected by atmospheric dust. Dr. Theodoros Christoudias, Associate Professor at the Cyprus Institute, explains that dust is a significant factor for solar energy systems in the Mediterranean. The research accurately measured energy production losses in real-world conditions, enhancing the accuracy of forecasts and enabling grid managers to prepare for unexpected production declines.
