Connecting your solar system to the grid

Because solar power systems can impact the performance of the electricity grid, you need to have approval from your electricity distributor to connect your system to the grid.

Network connection agreements

A network connection agreement must be lodged and approved by your electricity distributor before you have solar installed.

If you live:

Although this form is usually lodged on your behalf by your solar power installer, you should understand your electricity distributor’s process, and read Small-scale grid connection process for Queensland.

The agreement sets out the terms and conditions of your connection to the grid, including the size and type of system approved by your electricity distributor (and technical requirements that must be met).

Although this content is primarily for first-time solar power installers, if you currently have solar and are considering upgrading your inverter or increasing the number of solar panels on your roof, you should contact your electricity distributor about your network connection agreement. This should be done before making any changes to your current set up.

How your electricity meter operates

You will also need to have a new digital meter installed to measure the solar power you export to the grid. This is required before you connect to the grid.

This may mean you need to have your existing meter modified or a new meter installed.

The following explains how your new meter works with a solar power system:

  • electricity generated by the solar power system helps to power your home first
  • any excess electricity can be fed instantaneously into the grid
  • the meter records the amount of electricity you have exported to the grid, rather than the total amount of electricity generated by the solar power system
  • power comes from the electricity grid when the solar power system is not generating enough power.
