Reliable and efficient operation of photovoltaic systems.

Due to the energy transition, the number of photovoltaic systems on the roofs of private homes and commercial buildings is increasing rapidly. Like all electronic components, solar cells and modules as well as other electronic components must be checked regularly, especially since they are located outdoors.

Installation errors, severe weather and aging can cause defects in modules and components such as inverters that reduce energy output. Infrared thermography offers the possibility to locate problems on PV systems quickly, precisely and reliably.

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.
