While these areas can be easily identified from electroluminescense (EL) images, this is much harder for photoluminescence (PL) images.
Visual inspection of solar modules is an important monitoring facility in photovoltaic power plants.

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.
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.
