The growth of photovoltaic power plants in both size and number has spurred the development of new approaches in inspection techniques. The most commonly employed methods include visual inspections, current-voltage measurements, infrared thermography, and luminescence imaging.
However, the current approach has only been demonstrated in highly efficient SunPower interdigitated all back-contact (IBC) solar modules. The investigation with other types of PV modules becomes mandatory in order to consolidate the method as an inspection technique for solar PV power plants.
The most common inspection techniques employed in PV plants for assessing the performance of PV modules include visual inspection, current-voltage measurements (I-V curves), thermographic imaging, and luminescence imaging, which encompasses both electroluminescence and photoluminescence (Köntges et al., 2014).
Additionally, aerial inspections facilitate the measurement of PV facilities on roofs or floating PV power plants (Weber et al., 2016), which can be challenging or even impossible with conventional techniques that involve a camera placed on a tripod.
The inspection of each cell in the solar panel provides a useful tool to identify faults that reduce the power output of the panel, such as cracks, finger failures, humidity corrosion, shunt faults, or disconnected busbars. Additionally, it is possible to identify patterns within the PV module.
Solar farms need regular inspection for several reasons. For one, most PV systems are contractually obligated to undergo an inspection once or twice per year. On top of that, PV sites require commissioning inspections right after installation is complete.
