Segmentation of cell-level anomalies in electroluminescence images of photovoltaic modules. (arXiv:2106.10962v2 [cs.CV] UPDATED)

In the operation & maintenance (O&M) of photovoltaic (PV) plants, the early
identification of failures has become crucial to maintain productivity and
prolong components' life. Of all defects, cell-level anomalies can lead to
serious failures and may affect surrounding PV modules in the long run. These
fine defects are usually captured with high spatial resolution
electroluminescence (EL) imaging. The difficulty of acquiring such images has
limited the availability of data. For this work, multiple data resources and
augmentation techniques have …
