The Energy Intelligence Photovoltaic Assistance Centre manages the main issues encountered on photovoltaic systems in databases.

The Energy Intelligence Photovoltaic Assistance Centre manages the main issues encountered on photovoltaic systems in databases; it organises them into components, producers, seriousness and with the help of the 'Energy Lab, it defines the "case studies", intervention procedures to share the experiences and the "success cases" with the managed photovoltaic park. through analysis action, sharing and continuous improvement in the maintenance procedures, the main issues encountered on photovoltaic plants can be avoided due to preventive maintenance. Several of the main issues of photovoltaic plants are organised into a section called "laboratory cases":

Fotovoltaico Strutture mont2 Fotovoltaico Bava dil lumac2 

  • Support structures inadequate for the type of panel
  • Photovoltaic modules: examples of snail slime

Inverter Bosster rotti 2 Inverter bruciato 1

 

  • Inverter: Booster burst for manufacturing defect
  • Inverter: Fire caused by incorrectly fastened terminals and/or clamps

Cablaggio Roditori Fotovoltaico Ammoniaca

  • Wiring: Effects of rodents on electrical wiring between the panel and the base of the roof
  • Photovoltaic systems on farms: Effects of corrosion and mould due to air saturated with ammonia from farm animal excrement

Fotovoltaico Furto Cavi2 Fotovoltaico Furto Cavi 4

 

  • THEFTS: Theft of wires, wire cutting and cable holder emptying

Fotovoltaico Ossidato 1 Fotovoltaico Ossidato Retro

 

  • PHOTOVOLTAIC MODULES: Defects due to front and back module oxidation

 Difetto Trasformatore FV 1 Difetto Trasformatore FV 3

 

  • TRANSFORMER: Insertion defects on the coil

Fotovoltaico Scatola Giunzi Junction Box Lamelle stacc

 

  • JUNCTION BOX: Defects on the Bypass diodes mounted inside the junction boxes
  • PHOTOVOLTAIC MODULES: Defects due to front and back module oxidation
  • HOT SPOT: Defective cells, which appear as "hot spots" and which can be found through thermographic analysis
  • SNAIL SLIME: Visually recognizable defect as a superficial streak
  • PID: Difficult defect to identify that results in the silent performance reduction of the modules and photovoltaic systems. The high voltages between the frame and the cell push the charge into the active layer of the cell, preventing the removal of the generated loads (case study in EnergyLab)
