Maintenance and measurement includes the following services:

  • Visual inspection of the system and protective devices
  • Determination of the module power
  • Checking the substructure for mechanical or electrical damage and cable breakage
  • Testing the efficiency of the inverters
  • Visual inspection of additional external surge protection devices
  • On the AC side: check of all switching and protective devices for proper function and tight fit
  • Inspection of the stationary electrical systems and equipment for proper condition
  • Repetition of measurements and tests according to commissioning according to DIN VDE 0100-600 or DIN VDE 0126-23
  • thermographic measurements
  • Return flow thermography measurements
  • Electroluminescence measurements
  • Photography/Videography (also with high tripod)
  • Determination of the module power
  • Digital shading analysis
