Solar panel system maintenance

21 June 2018

The Clean Energy Regulator does not regulate, or have expertise in, the maintenance of solar panel systems. However, below we have set out some general tips you may wish to consider when you are seeking to engage someone to provide maintenance services.

Why do I need to maintain my solar panel system?

It is important that regular maintenance is carried out on your solar panel system. Undertaking regular maintenance will ensure your solar panel system is operating safely, correctly and efficiently.

Over time dust and debris will build up on your solar panels, which may compromise the performance of your solar panel system. In addition, water and moisture seepage, vermin, hail, wind and sunlight can all cause damage or deterioration to your system.

By ensuring regular routine maintenance is undertaken, you can ensure your solar panel system is safe for everyone living in the premises, along with electrical workers working on the distribution network. Routine maintenance will also ensure system performance is maintained, allowing you to maximise savings on your power bills for many years.

Just like running a car, regular servicing is the best way to ensure your solar panel system keeps operating safely, correctly and efficiently.

How often do I need to maintain my solar panel system?

Like all electrical equipment, regular maintenance of your solar panel system is necessary. Please take note of and follow the maintenance schedule provided by your solar retailer or installer.

Don’t forget: Keep all the paperwork from your installation, as some faults may be covered by warranties.

Who can undertake routine maintenance on my solar panel system?

Unlike typical electrical products, turning a solar panel system ‘off’ at the switch does not mean that the components no longer pose an electrical hazard. In addition, for roof mounted systems, some maintenance tasks may need to be conducted on the roof which poses additional hazards.

It is recommended that solar panel systems should only be inspected and maintained by a licenced electrician or Clean Energy Council-accredited solar panel system installer.

What is involved?

Maintaining your solar panel system involves much more than simply cleaning your solar panels. Regular maintenance of your solar panel system should ensure:

  • solar panels are clean, secure and free of defects
  • no parts have deteriorated/corroded
  • vents are free of debris
  • switches do not have any defects
  • wiring has not been damaged/has not deteriorated
  • electrical checks to ensure all components are operating as intended
  • confirming fittings and cables are securely attached
  • reviewing the inverter display panel for recorded faults
  • checking that access to the isolator switches has not been impeded, and/or
  • making sure the emergency procedures for shutdown and isolation are clearly displayed.
