New Method Uses Machine Learning to Predict Solar Panel Soiling Losses
The University of Cyprus has conducted research comparing different methods to accurately predict losses from dust accumulation on solar panels. Dust and dry conditions pose challenges for PV system performance, leading to significant revenue losses. Therefore, accurately forecasting the impact of soiling on short and long-term timescales is crucial for PV project developers and operators.
The study evaluated six models, including three physical models and three machine learning models. Physical models rely on established techniques, while machine learning models are open-source programs used for the first time in measuring soiling. The models were compared against data from a test installation at the University of Cyprus campus in Nicosia.
According to the evaluations, the physical models achieved the highest accuracy by using field observed data. The root mean square error for daily soiling losses was 1.16% for the physical models, while monthly soiling losses showed an error rate of 0.83%. The best-performing machine learning model called CatBoost had an error rate of 1.55% for daily soiling losses and 1.18% for monthly losses. Researchers note that machine learning models could be beneficial in regions with limited field-observed data, as they rely on environmental data gathered by satellite.
The application of machine learning models in predicting soiling losses could aid in implementing effective operations and maintenance strategies, minimizing revenue loss caused by dust and aridity. Especially in regions with frequent changes in aerosol loading and limited precipitation, modeling soiling using satellite-derived environmental data offers a potential solution.
The study provides valuable insights into predicting soiling losses for PV systems, highlighting the effectiveness of both physical models and machine learning approaches. Developers and operators can leverage these findings to optimize cleaning schedules and select appropriate cleaning equipment, enhancing the economics of their projects. By staying one step ahead of soiling, the solar industry can mitigate losses and maximize revenue while ensuring the efficient performance of PV systems.
In conclusion, this research showcases the potential of machine learning in accurately predicting and addressing the challenges posed by dusty and dry conditions on solar panels. By harnessing the power of data and innovative approaches, the solar industry can stay ahead of the game and optimize the performance of PV systems for a sustainable future.
