Monitoring and checking photovoltaic plants

Using solar thermography, module defects and installation faults can be reliably detected – for example:

  • Hot-spots due to module defects, Modules at open circuit
  • Short-circuits, Loose contacts, Overheated cables and connection sockets

The requirements of plant security and personal protection can be combined in a solar-thermographic examination:

  • Malfunctions are easy to detect on thermal images, and smooth functioning of all components is guaranteed, thus achieving danger-free operation of the photovoltaic plant.
  • Thanks to measurement from a safe distance, optimum personal protection is guaranteed at all times.

Efficient maintenance of solar parks

In particular for large photovoltaic plants, regular thorough checks are essential, as a malfunction in a single solar cell can already have a negative effect on the yield of the overall plants.

  • Time-saving measurement: Even with hundreds of square metres of module area and changing intensity of solar irradiation, solar thermography represents a very efficient method for searching for thermal anomalies.

Increased measurement certainty thanks to solar radiation intensity input

  • Solar mode: The solar radiation intensity value can be stored together with the thermal image and is then available for the image analysis.
