How warranty claims
work.
Report Issue
Contact our support team via phone, email or through your monitoring app. Describe the issue and we'll begin assessment.
Remote Diagnosis
Our technical team reviews your system data remotely to identify the fault. Many issues can be resolved without a site visit.
Warranty Claim
If a component has failed, we lodge the warranty claim with the manufacturer and arrange replacement at no cost to you.
Resolution
Replacement component installed and tested by a SAA-accredited technician. System back to full operation with verified performance.
What's not covered.
Transparency is core to our values. Here's what falls outside standard warranty coverage.
Storm & Flood Damage
Damage caused by extreme weather events including storms, floods, hail, lightning strikes or cyclones. These are typically covered by your home insurance.
Unauthorised Modifications
Any modifications, repairs or alterations performed by non-SAA accredited technicians or without Mission Green's written approval.
Normal Degradation Within Spec
Gradual performance reduction that remains within the manufacturer's published degradation curve (e.g. panels producing above 84.8% at year 25).
Cosmetic Wear
Surface scratches, minor discolouration or cosmetic blemishes that do not affect system performance or energy output.
Non-SAA Installation
Systems not installed by SAA-accredited installers, or installations that do not comply with Australian Standards (AS/NZS 5033).
Grid & Utility Faults
Issues caused by grid voltage fluctuations, utility outages, power surges from the network or changes to feed-in tariff regulations.
Warranties transfer.
All Mission Green warranties transfer automatically to new property owners.
How to transfer
Simply notify us of the ownership change by emailing support@missiongreen.com.au with the new owner's details and your installation reference number. We'll update all warranty records within 5 business days — at no cost.
