Combination of three methods of photovoltaic panels damage evaluation

In broken photovoltaic (PV) cells the flow of electric current can be reduced in some places, which results in a lowered efficiency. In the present study, the damage of PV cells and panels was evaluated using three methods – electroluminescence, infrared camera imaging, and visual examination. The damage is detectable by all these methods which were presented and compared from the viewpoint of resolution, difficulty, and accuracy of monitoring the PV panels damage.
