Rooftop solar PV inspection activities

The overall rooftop solar PV inspection activity can be divided into two stages:

  • visual inspection
  • testing of the PV system

Visual inspection is done to:

  • verify Installation, interconnection, workmanship, warranty compliance, ratings of equipment, labelling, etc.
  • Safety via over-current/ voltage protection devices, residual current devices, surge and lightning protection, disconnectors, earthing and other contingencies.

Testing of the system id done to: 

  • access performance of PV modules;
  • check the functioning and generation parameters and overall output of the inverter. This also results in identifying issues with PV array and strings using inverter values;
  • test the safety aspects as per standards and regulatory requirements for continuity, short circuit and open circuit, polarity, earthing, insulation, islanding etc.
