Getting connected to the grid

You can usually expect your solar PV system or battery application, installation and connection process to take up to three months, from the time you accept your chosen supplier’s quote until your system is ready to use. 

The actual timeframe will depend on a number of factors including your supplier, product availability and how long it takes to get local council approval (if applicable) and Western Power approval.

Watch this short video to learn about the connection application process.

Our role in your solar connection

To get the connection process started, you or your solar supplier will need to apply to Synergy to get a reference number. 

To apply for your Synergy reference number, you’ll need:

  • A copy of your Synergy bill
  • Details of the system or battery size
  • Your installer’s contact details 

In most cases, we’ll give you a reference number within one business day. Once you have your reference number, you can then apply to Western Power to connect your system to the grid. Your supplier might do this on your behalf.

If you're eligible, we'll also buy back any excess electricity you generate from your solar PV system and export back to the grid under the Distributed Energy Buyback Scheme, or DEBS.* We'll let you know if you're eligible for DEBS during the connection process.  

*DEBS terms and conditions apply. 

Here's a quick guide to the steps involved in the process of getting your solar PV system or battery connected to the grid.

  • Apply for approvals
    Once you’ve accepted your supplier’s quote, they could apply to Western Power on your behalf for approval to connect to the network. 

    Depending on where you live, you may also need to apply for approval from your local council. Speak with your supplier and local council to find out whether approval is required.

  • Your system gets installed
    Once your application has been approved by Western Power (and your local council, if necessary) your supplier will book a date and time for your system to be installed. This should only be done by an accredited installer. 

    On the installation day, your electricity will be completely shut off so your system can be safely installed and commissioned. Your supplier should let you know about the installation processes and anything else you can expect on the day.

  • Your solar is connected
    Once your system has been installed, commissioned and tested, it will be connected to the grid and ready to generate or store electricity for your home. You should receive a handover from your supplier about your system and whether there are any apps you can access to help you monitor the performance of your system.

  • Make the most of your solar at home
    The best way to make the most of your solar PV system is to use as much of the electricity it generates as you can during the day as it is being generated. This could involve small habit changes such as using a timer to run your washing machine at lunchtime instead of overnight when you draw electricity from the grid.
