Solar Panel Inspection

Solar Panel Inspection

Complete your solar panel inspection faster and with less risk when they are installed at height.  From regular inspections to details analysis in partnership with your team we can help.

How can a Drone / UAV help?

Solar farms are typically very large installations and a drone equipped with an appropriate thermal camera will be able to scan the site for defects much faster than using a thermal camera on the ground.

A thermal camera can help identify: manufacturing defects, cracks, faulty inter-connectors, defective bypass diodes and temporary shadowing.

Our Equipment

Our primary platform for inspection work is the Zenith which is equipped with a visible light camera with a 10x zoom and a thermal camera.  Using thermal imaging cameras for solar panel evaluation offers several advantages:

  • Anomalies can clearly be seen on a crisp thermal image.
  • Thermal cameras can be used to scan installed solar panels during normal operation.
  • Thermal cameras on a drone also enable scanning of large areas within a short time frame.

The Zenith has a larger operating envelope than most UAVs as it is able to operate in high winds and also in light rain and snow.

We also operate with £10m of public liability for your peace of mind.


When undertaking thermographic inspections, the sky should be clear since clouds reduce solar irradiance and also produce interference through reflections.  Informative images can, however, be obtained even with an overcast sky, provided that the thermal imaging camera used is sufficiently sensitive.  Calm conditions are desirable, since any airflow on the surface of the solar module will cause convective cooling and will reduce the thermal gradient. The cooler the air temperature, the higher the potential thermal contrast meaning that early mornings are an ideal time to conduct these inspections.

Solar installations collect operating data that can be used to direct the inspection effort, call us to find out more.
