Solar problems and maintenance

Learn how to maintain your solar and battery system and repair it in case of a fault.

Prevent faults in your solar

Maintaining your solar ensures that it's operating correctly, optimises its performance and keeps the system safe.

Hot spots and microcracks are the most common faults that can occur in your solar, and you can reduce the chances of both by regularly cleaning your solar panels from dirt and grime.

Hot spots can occur when dirt and other substances like bird droppings accumulate on a panel, placing extra load on the cleaner parts of the panel. This can cause microcracks to form, compromising the system as a whole. Solar panels only self-clean in the rain to a small extent, as stickier substances like bird and possum droppings may harden over time and not wash off easily, even in heavy rain.

For safety reasons, we do not recommend you clean the panels yourself, either on the roof or from the ground. Cleaning, system health checks and maintenance work should be left to a qualified tradesperson.

Beyond regular cleaning and technician health checks, monitoring your system can be a good way to check the health of your solar and ensuring its output is what you expect. If you have a smart meter, you can check MyAccount or your AGL App for a feature called Solar Status. Learn more about this free solar health check service.

Repairing a solar panel system

While maintenance reduces the risk of faults in your home solar, faults requiring repairs can still occur from problems like moisture damage, electrical issues and certain weather events.

All systems installed by AGL come with an AGL workmanship warranty (typically five years), as well as a manufacturer’s warranty. You may also have rights under the Australian Consumer Law. If your system was installed by AGL, we may be able to help you troubleshoot the fault if you get in touch with us.

For solar not installed by AGL, contact the original installer to see if your repairs can be done under warranty. If you cannot contact the installer, you should be able to find contact details of your system's manufacturer on your warranty documentation. Never try to fix an electrical issue yourself.

For solar systems not under warranty, we recommend you perform a Solar Health Check via MyAccount or the AGL App. The Solar Health Check can be found via the Solar Status feature and provides details of service technicians that AGL recommends.

Solar inspection schedules

When having your solar installed, ask your accredited installer what state regulations apply to you when it comes to inspections and maintenance. Your installer should also provide you with a schedule of regular maintenance. If you don't know when your last inspection was, we recommend organising an inspection of your system with a Clean Energy Council-accredited solar panel system installer.

Under the Renewable Energy Target, the Clean Energy Regulator conducts random inspections on small-scale generation units with small-scale technology certificates created against them. The system owner is not charged for these random inspections.
