What does a commercial solar inspection cover?

A comprehensive commercial solar inspection covers panel condition (soiling, physical damage, delamination, and shading assessment), DC wiring and connection integrity, inverter operation and fault log review, mounting and racking condition, earthing and bonding, and production data review against the original 30-year financial model.

Clear answer, explained.

Where a battery storage system is co-located, the inspection extends to the storage system, BMS, and interconnection.


Key points

What this means in practice.

  • Panel condition: soiling, physical damage, delamination, and shading assessment
  • DC wiring and connection integrity — checking for degradation, loose connections, and insulation condition
  • Inverter operation and fault log review — confirming operation and identifying any recorded faults
  • Mounting and racking condition — checking for structural integrity and corrosion
  • Earthing and bonding — confirming electrical safety compliance
  • Production data review against the original 30-year financial model — quantifying any performance gap

When this applies

Best-fit environments.

  • You are planning an annual inspection and want to understand exactly what the inspection covers
  • You have just acquired a system installed by another company and want to commission a baseline inspection
  • Your system has shown monitoring anomalies and you want to understand what the site inspection will assess
  • You have a co-located battery storage system and want to confirm the inspection covers both systems
