Instead, we frame fault detection as more realistic unsupervised domain adaptation problem where we train on labelled data of one source PV plant and make predictions on another target plant.

While these areas can be easily identified from electroluminescense (EL) images, this is much harder for photoluminescence (PL) images.

However, knowledge of the power at maximum power point is important as well, since drops in the power of a single module can affect the performance of an entire string.

To this end, we apply normalized Lp normalization to aggregate the activation maps into single scores for classification.

We compare our method to the state of the art and show that it is superior in presence of perspective distortion while the performance on images, where the module is roughly coplanar to the detector, is similar to the reference method.

We assume that our analysis will support further investigation of known operators in other fields of physics, imaging, and signal processing.
