Thermal Imaging Solar Farm Survey

Mast/drone thermal imaging surveys for photovoltaic installations.



Our aerial thermal imaging surveys can detect and accurately locate faulty cells, string-errors, organic debris, defective diodes and PID faults on solar farm installations. Our drones conduct technical inspections using specialist, purpose-built thermal imaging cameras that are an ideal solution for identifying thermal anomalies and maximising energy production.

Faulty cells operate at a temperature (hot or cold) different to that of normal cells, meaning we can easily pin-point the location of cell faults either by GPS – referenced to a site map – or by using graphical overlays. Thermal imaging cameras are capable of detecting minor temperature differences caused by stray currents in crystalline photovoltaic modules (known as potential induced performance degradation or PID) aswell as the early detection of defective diodes.

Key Points

  • Detect and accurately locate faulty cells

  • Detect and accurately locate string errors

  • Detect and locate minor temperature differences caused by stray currents (PID Faults)

  • Early detection of defective diodes, reducing potential voltage loss.

CAA Approved

iRed has ‘Permissions for Commercial Operations’ (PfCO) from the Civil Aviation Authority (id No. 2082) to operate unmanned aerial vehicles (drones) commercially.


After the successful completion of a thermal imaging survey, clients will receive an in-depth report written by a BINDT (British Institute of Non-Destructive Testing)  accredited PCN Category 2 thermographer. The report, comprised of thermal imagery and detailed analysis, will outline any potential issues or areas of concern.
