Solar Panel Commissioning: What Should Be Tested Before Handover?

Sarah Kimani· 1 min read

Commissioning is the final technical stage of a solar installation. It confirms that the system has been installed correctly, electrical protection operates appropriately and the monitoring system is configured.

What is tested?

  • Electrical connections
  • Protective devices
  • Isolation arrangements
  • Inverter operation
  • Solar generation
  • Battery operation where installed
  • Monitoring communications
  • System configuration

Why is monitoring important?

Monitoring allows the homeowner to see energy generation and identify unusual changes in system performance. It also provides useful information when diagnosing future faults.

What should the homeowner receive?

  • System documentation
  • Equipment information
  • Warranty details
  • Monitoring access
  • Relevant electrical certification
  • Operating instructions

Do not treat commissioning as paperwork

Proper commissioning verifies that the installed system actually operates as designed.
