Validation Of Photovoltaic Plant Loss Estimation From Monitoring Data: String Faults, Shading and Degradation

Monitoring of a photovoltiac plant improves its performance by maximizing energy production as well as minimizing economic losses. Thus, identification and quantification of such performance losses is necessary to avoid them. 3E's monitoring platform provides a detailed loss breakdown analysis with performance losses due to soiling, shading, degradation, etc. The main focus of this study is the validation of string faults, shading and degradation losses against complementary results from thermal and visual drone imagery.
