Abstract: In the operation of photovoltaic power plants, precise knowledge of shading is essential in order to carry out differentiated yield and site analyses and to guarantee reliable monitoring and fault detection. A study on the causes of shading carried out with the help of GPT4-o is presented. Subsequently, an innovative approach for predicting shading using a is introduced. By combining physical and data-driven machine learning, it is possible to efficiently complete incomplete shadow analyses and eliminate erroneous data points of a physical model. The presented method utilizes data from 1380 photovoltaic devices with various shading scenarios to train an autoencoder on PV system shading. The autoencoder enables accurate prediction of shading within a detection time of only a few weeks.
