Read the remedy, not just the year count. Check the cause, evidence to keep, recovery steps, and escalation.

For every installed model, save the warranty PDF that was in force when it was sold and answer.

What applies to this exact problem

For every installed model, save the warranty PDF that was in force when it was sold and answer:

  • Who is the legal warrantor and where must a claim be filed?
  • Does registration or transfer to a new owner matter?
  • Which serial number, invoice and commissioning records are required?
  • How is a defect or degraded output tested, and by whom?
  • Can the warrantor repair, replace, provide a refurbished unit or pay a depreciated amount?
  • Who pays diagnosis, scaffolding, removal, packing, freight, customs, labour and reinstallation?
  • Do replacement parts inherit the original end date or receive a new term?
  • Which events are excluded: corrosion zone, unauthorised work, grid event, surge, flood, fire, pests or improper maintenance?

U.S. Department of Energy project guidance usefully tells asset owners to document underperformance and check whether repair/replacement, labour, removal, shipping and reinstallation are included. That is technical contract-reading guidance, not Indian warranty law; your signed Indian contracts and applicable law control.

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
