Comparative observation, also called qualitative thermography, allows sufficiently reliable statements to be made in many inspection situations.
Inspection by drone and thermal imaging camera proves to be very effective as it enables a trained surveyor to detect potential defects or yield loss.
The following are some examples of defects that appear time and time again:
The following are some examples of defects that appear again and again: Faulty bypass diodes, contact faults in solar cells, soiling, moisture penetration, short circuits in solar cells, cracks in the module glass, loose contact points, cracks in cells, defective wiring, etc.
Experience has shown that we recommend such an appraisal only a few months after commissioning, in order to clear up possible asset deficits from the very beginning.
