With the help of thermographic imaging, we can make hotspots in solar panels visible. This form of testing can be conducted after the modules have already been installed on a roof or in a farm. The inspection does require the right weather conditions, however. For instance, the power of the sun’s rays must be at least 600 Watt per square metre, and the wind speed may not be over xxx kilometres per hour (max wind speed depends on the location of the testing). In collaboration with our partners, we can create thermographic imaging of large-scale products through the use of a drone. The use of a drone is subject to strict regulation and therefore not permitted everywhere. Using our own equipment, we can do a sample test of the project to then inspect suspect panels in more detail by performing an electroluminescence test. The photos on this page show some of the thermographic images we have made at our customers. The lighter areas in the picture are cells that are hotter than other cells in the module.

Our thermographic inspection consists heat images made by a drone and if requested, analyzes of those images. We perform the following analyses on the images/data, among others:

  • Hotspots
  • Bypassed diodes
  • PID
  • String issues

You can also choose to have a quick scan of your system made periodically in order to avoid running into production backlogs after the summer months. Click here for more information about the periodic check.
