Photovoltaic systems
Fast and reliable fault detection.
With thermal imagers from Testo.
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. To ensure that solar cells, modules and other electronic components work efficiently outdoors in the long term, regular monitoring is essential.
Installation errors, weather influences and wear can cause defects in modules and components such as inverters, that considerably reduce energy output. Infrared thermography can be used to detect such problems quickly, precisely and reliably.
A thorough inspection is particularly important for large systems such as solar parks, as even a single defective solar cell can affect the yield of the entire system. Thermal imagers from Testo offer the ideal solution for this – especially for module connections and components that are difficult to access. This ensures that your PV system delivers its maximum output in the long term.
Detect thermal anomalies on photovoltaic systems quickly, safely, and reliably
occurs when an inactive cell continues to be supplied with power by the active cells, e.g. due to lightning or hail.
the cell then converts this energy into heat.
The resultant “hotspots” could even destroy the module.
Overheated cells can be identified very easily with the thermal imager
