Photovoltaic thermography

Possible errors and defects on individual solar modules or on the entire PV system can be identified using the measuring and testing procedure photovoltaic thermography. This makes use of the heat radiation from the PV modules.

 

TESTING OF PHOTOVOLATIC MODULES USING THERMOGRAPHY

In order for a photovoltaic system to achieve the best possible return at all times, solar modules, as well as the solar cells, need to consistently work flawlessly. Solar cells can overheat should they not be functioning correctly. Typically, this can lead to failure of complete modules and thus to a reduction in yield. In rare cases, damage to the insulation and arcing are possible.

 

In order to eliminate such errors, even the smallest errors and defects can be detected in solar modules using an infrared camera. The thermography images will show any signs of errors and overheating on the front or back of the PV modules.

 

Photovoltaic modules are not the only components that can be studied using thermography. Cables, solar connectors, transformers and inverters can also be analysed and evaluated by means of thermal imaging.

 

TESTING THE COMPLETE PV SYSTEM OR INDIVIDUAL PV MODULES USING THERMOGRAPHY

Thermography is a non-contact inspection. However, it is depend on weather conditions and requires sufficient sunlight.

 

The technician has various options to examine the photovoltaic system. The PV generator can be checked from a distance using the infrared camera. Technicians can also get closer by using lifting equipment, ladders and walking on the roof.

 

Thermography makes it possible to identify possible sources of error and weaknesses of photovoltaic systems quickly and easily.
