Solar panels are designed to operate outdoors for many years, but that does not mean a solar system should simply
be installed and forgotten.
Regular monitoring and maintenance can help identify issues, maintain system performance and ensure problems are addressed before they become more significant.
The Australian Government recommends checking system performance and following an appropriate maintenance schedule. It notes that a solar system may be professionally serviced approximately every two years, although the appropriate schedule depends on the system and circumstances.
Do Solar Panels Need Maintenance?
Yes, although solar systems generally do not require constant maintenance. Over time, panels and other components can be affected by:
• Dirt and debris
• Vegetation and shading
• Weather exposure
• Damaged cables or components
• Inverter faults
• Changes in system performance
• Physical damage
Solar generation also naturally varies depending on weather, season, time of day and location, so a temporary reduction in output does not automatically indicate a fault.
How Often Should a Solar System Be Serviced?
There is no single schedule that applies to every solar installation.
The Australian Government recommends checking the system documentation or asking the installer what maintenance schedule is appropriate. A professional service may be suitable around every two years.
Properties in dusty environments, locations with significant vegetation or systems showing performance issues may require additional attention.
What Does Solar Panel Maintenance Include?
A professional solar service can involve more than simply washing the panels.
Depending on the system, maintenance may include:
Panel cleaning
Removing dirt and debris that may affect generation.
Electrical inspection
Checking electrical components and connections.
Cable and isolator inspection
Looking for issues that may affect safe operation.
Inverter inspection
Reviewing the inverter and checking recorded faults.
System performance review
Comparing generation and identifying unusual changes.
Area around the panels
Checking for vegetation, debris or other issues affecting the system.
These are among the maintenance activities identified in Australian Government guidance.
Don't Wait for Your Electricity Bill to Tell You Something Is Wrong One of the easiest ways to monitor a solar system is through its monitoring platform or app.
Most solar and battery systems provide some form of monitoring, allowing owners to see generation and, where applicable, battery charging and discharging.
A noticeable and unexplained change in generation on otherwise comparable sunny days can be a reason to investigate.
When Should You Arrange a Solar Inspection?
Consider having the system checked if you notice:
• Unexpectedly low generation
• Inverter fault messages
• Visible damage
• Damaged or obstructed equipment
• New shading from vegetation
• Unusual system behaviour
• A significant change in performance
• Repairs or electrical work should be carried out by an appropriately qualified professional.
