Raptor Photonics has published an application note explaining how its SWIR (short-wave infrared) cameras can be used in drone-based electroluminescence (EL) imaging of photovoltaic (PV) solar panels. This imaging process provides detailed high-accuracy detection of defects and faults in the panels, such as cracks, broken cells, interconnections and shunts.

EL imaging is normally only undertaken either indoors or between dusk and dawn outdoors, due to the fact that the luminescence signal of crystalline silicon, which PV panels are constructed from,...
