Low-cost machine learning framework for snail trail detection in PV panels

Conceived by French scientists, the novel system uses ensemble learning and does not require anything more than a commercially available optimizer. Before it makes a decision, the method combines K nearest neighbors, support vector machine, and decision tree learning. Accuracy is reportedly up to 89%. A research group led by France's University of Toulouse has developed a novel detection method for snail trails in solar modules. The process uses an ensemble learning framework dubbed ELDIAG to analyze the PV panel's time-frequency characteristics and statistics. It collects data from commercially ...
