Thermography on photovoltaic systems

Thermography on photovoltaic systems Quick and efficient. You can now easily monitor photovoltaic systems of all sizes in a way that is wide-ranging, contactless and exceptionally efficient. This is because the accurate thermal imagers from Testo are able to detect malfunctions and ensure that all components function smoothly, ensuring maximum cost effectiveness. The option of inputting solar radiation intensity offers you extra reliability and afterwards you will know exactly, what you have measured. Risks in operating photovoltaic systems. Faults that occur when operating photovoltaic systems can be quickly diagnosed from a solar radiation of 500 – 600 W/ m² via marked changes to the thermal properties using Testo thermal imagers: Defective bypass diodes Contact faults and short circuits in solar cells Penetrated humidity, contamination Cracks in cells or in the module' s glass Non-functioning or disconnected modules So-called mismatches, i.e. loss of performance due to different capacities of individual modules In thermographic measurement, it is important that you note the intensity of the solar radiation. This is because values that are too low distort the results.
