← Full guide: Solar Earthing and Surge Protection: Safety Checklist

Review solar electrical safety without turning it into a DIY high-voltage job

Review solar electrical safety without turning it into a DIY high-voltage job. Check the cause, evidence to keep, recovery steps, and escalation.

Start here

You should be able to see how modules, strings, inverter, AC connection, isolation, earthing and surge-protection devices fit together.

What applies to this exact problem

1. Ask for the single-line diagram and protection schedule

You should be able to see how modules, strings, inverter, AC connection, isolation, earthing and surge-protection devices fit together.

2. Match the design to the installation

Model numbers, cable routes, isolators, protection devices and earthing conductors on site should correspond to the approved design or a documented as-built drawing.

3. Request test and commissioning records

Ask what electrical tests were performed, who performed them, the instruments or standards used, and the signed acceptance record.

4. Inspect visually from safe locations

Look for damaged enclosures, loose visible conduits, exposed conductors, water ingress or corrosion. Do not open inverter or DC combiner compartments unless qualified and authorised.

5. Escalate defects before normal operation

If protection is missing, visibly damaged or undocumented, obtain qualified inspection and written remediation instead of improvising a repair.

Check these first

  • State the exact expected result and the exact result you have now.
  • Find the official record that owns the result and compare it with your evidence.
  • Change one thing at a time, then verify the final state before moving on.

Fix it in this order

  1. State the exact expected result and the exact result you have now.
  2. Find the official record that owns the result and compare it with your evidence.
  3. Separate hardware, installer, DISCOM/net-meter, portal, and subsidy status. They are different failure points.
  4. Record system size, module/inverter details, commissioning date, generation data, application IDs, and promised scope.
  5. Compare actual installation and generation with the signed quote, warranty, and portal/DISCOM records.
  6. Ask the responsible party for the exact pending action and owner of that action in writing.
  7. Do not close the job until safety checks, commissioning, monitoring, and applicable net-meter/subsidy records reconcile.

Build the proof pack

  • Signed quote and scope
  • Module/inverter serials and warranty
  • DISCOM/portal application IDs
  • Generation data, photos, and installer tickets

Avoid making the case harder

  • Paying the final amount before checking agreed milestones
  • Assuming low generation is automatically a bad panel
  • Treating installer completion as DISCOM/subsidy completion

How you know it is really fixed

  • The official record and your real-world result agree.
  • You have enough written evidence to prove the issue is finished if it returns later.

If it is still not fixed

  1. Installer/vendor grievance
  2. DISCOM/portal grievance route
  3. Consumer forum or other official remedy where appropriate
