Electroluminescence (EL) imaging and infrared (IRT) thermography techniques have become indispensable tools in recent years for health diagnostic of PV modules in solar industry application. We propose a diagnostic setup which performs lock-in EL for accurate analysis of different types of faults occurring in a solar module.
The setup is built around a high-speed SWIR camera, which can acquire images at very short integration time (1 µs), and high frame rate (301 fps). In addition, a state-of-the-art imaging chamber allows for introducing controlled levels of ambient light noise, rotation of panel frame in xyz direction for developing new light noise removal techniques.
The purpose of the diagnostic setup is to support research in PV failure quantification through EL imaging which can also be useful for aerial drone imaging of PV plants.
