Solar Feed-in Tariffs – State by State

State Solar Feed-In Tariffs

State and Territory governments across Australia have adopted different approaches to what is normally referred to as a solar feed-in tariff, sometimes known as a solar bonus scheme or solar buy-back scheme.

Solar feed-in tariffs are a payment for the clean energy that your solar panels feed back into the grid. There have been many changes to feed-in tariff legislation in all states and territories over the past few years. (For an overview of the current incentives offered see our summary table below.)

Although the premium tariffs are no longer in place, low solar PV system prices mean that they are no longer as important as they once were for solar to make financial sense. Increasing electricity costs are now the main reason to invest in a solar PV system, as it offers home owners a means of taking control of their energy bills (read more about ‘solar self-consumption‘).

Available Feed-In Tariff schemes

The solar feed-in tariff schemes that are currently available in Australia – with the exception of Darwin – are ‘net’ schemes. A net feed-in tariff rewards you for each unit of solar power that you have exported to the electrical grid, in excess of what you manage to use yourself. (Darwin’s ‘gross’ feed-in tariff may as well be a net tariff because the purchase rates are the same as the feed-in rates.)

In addition to varying rates, each network has its own rules for connecting solar systems, with limits on certain system sizes. You can see an overview of these limits in our article about system size limits by electricity network, which contains a state-by-state table.

The following table summarises the current status of solar feed-in tariffs across the states and territories of Australia – it is relevant for households thinking about going solar today. For information on historic rates, please see this article.
