Getting the Most Out of Your Solar Investment

Regular maintenance and understanding the responsibilities of having a solar connection, will assist in getting the most our of a solar investment.

Installing solar on a home or business is one of the many ways people can take control of their electricity use and reduce their electricity bills. Whilst there are many benefits, the efficiency of a solar PV system can degrade over time so it’s important to maintain the system to get the most out of the solar investment.


Regular maintenance checks can help ensure the installation meets safety requirements and is operating efficiently. We suggest there are organised through a registered electrical contractor or installer.

The dustier the area, the more frequent inspection is recommended. This ensures dirt, grime, bird droppings and debris don’t block the sun from efficient absorption by the panels.

Check Usage

Customers can register for myEnergy, our online usage portal, which allows them to see how much solar is being exported back to the grid and to learn more about the latest feed in tariffs. A variation in usage can indicate the system requires attention.


It is important everyone understand their obligations. Under the Electricity Distribution Code owners of small embedded generators must comply with the code under its generation license.

  • Ensure that your generating source is capable of continuous uninterrupted operation at the system frequency of 50 Hz (or within any allowable variation that applies).
  • Ensure that your generating source and any associated equipment that is connected to the electricity network complies with Victoria’s Electricity Distribution Code, the Electricity Safety Act 1998 and all relevant Australian Standards and is maintained in a safe condition.
  • Ensure that your generating source’s electrical protection device meets the requirements of our electricity distribution system at all times. All grid interactive solar inverters which are connected to the Powercor network have to comply with AS4777 Australian Standard.

Additional Resources

To help you understand and meet these obligations, we recommend the Clean Energy Council’s Guide to Installing PV for Households, which contains a section on maintenance on page 20.


The safety of the community and our employees is our top priority. We may disconnect or ask you to disconnect your generating source if it is not safe, interferes with the local network or does not comply with the regulatory requirements referred to above.
