Solar rebates and support in SA
A clear guide to the financial support available when you install solar in South Australia: the federal scheme that lowers the upfront cost of panels, the federal battery scheme, and how feed-in tariffs work in SA, where rates are set by retailers rather than a state minimum.

The short answer
Solar support in South Australia is led by the federal government. A federal scheme reduces the upfront cost of solar panels, and a separate federal scheme takes roughly a third off an eligible home battery. South Australia's own Home Battery Scheme has closed, so the federal scheme, along with retailer Virtual Power Plant offers, is the battery support to know about. South Australia does not set a state minimum feed-in tariff, so the rate you are paid for exported power is set by your retailer. With some of the highest power prices in the country, the biggest saving comes from using your own solar. Figures are reviewed regularly, so a quote is the best way to know what applies.
The federal scheme for solar panels
The main support that lowers the upfront cost of a solar panel system in South Australia is a national scheme run by the Australian Government. It applies in SA exactly as it does in every other state.
The scheme works through small-scale technology certificates. When an eligible system is installed, it creates a number of certificates based on the system's size and its expected generation. Those certificates have a market value, and in practice your installer claims them and applies that value as a discount on the price you pay. You do not apply separately, the saving comes off the upfront price at the point of sale.
South Australia's strong sunshine means systems here generate well, which affects the certificate calculation. The value of the certificates moves with the market, and the scheme reduces over time on a set schedule, so the exact discount on a given system changes. South Australia does not run its own state rebate for solar panels, so this federal scheme is the main support for the panels themselves. Your installer's quote reflects the rate that applies when you buy.
Support for home batteries in SA
For batteries, South Australia relies on a federal scheme, with extra value available through retailer Virtual Power Plant offers.
The federal battery scheme
The Australian Government runs a national scheme that reduces the upfront cost of an eligible home battery, broadly around a third of the cost, applied as an upfront discount by your installer using the same certificate mechanism as the solar panel scheme. It is not means tested, and the value per unit of storage steps down over time.
The closed state scheme
South Australia ran its own Home Battery Scheme, one of the first in the country, but it has closed to new applications and has not been replaced. If you remember the SA Home Battery Scheme, this is why you will not find it now. Many households also join a retailer Virtual Power Plant, which can add value in return for letting the network draw on the battery at peak times.
The SA feed-in tariff
A feed-in tariff credits you for surplus solar power your home exports to the grid. When your panels generate more than your home is using, the excess flows to the grid and you are credited for it on your power bill.
South Australia is different from some states here: there is no state-mandated minimum feed-in rate. Instead, rates are set by individual retailers competing for customers, so they vary between retailers and plans. That makes it worth comparing offers rather than assuming a single number, and worth looking at the whole plan rather than the export rate alone.
There is also a technical point worth knowing. For systems installed more recently, South Australia uses a flexible exports approach, which lets a system export more to the grid when the network has capacity rather than being held to a fixed low limit. Either way, because feed-in rates are modest and SA grid prices are high, the better financial move is usually to use your own solar during the day, or store it in a battery for the evening, rather than export it cheaply. The feed-in tariff is a useful addition on top of self-consumption, not the main benefit.

The summary below reflects the position as at the date shown. Solar support is reviewed regularly. Always confirm the current detail with your installer when you request a quote.
Last checked: May 2026. The federal scheme values step down over time, with the battery rebate reducing every six months from 1 May 2026, and feed-in rates are set by retailers and change between plans. If you are reading this later, confirm the current support before relying on it.

A few practical points help you get genuine value from the schemes rather than just assuming a headline figure.
Use a quote, not a headline
The schemes are applied by your installer at the current rate. A quote shows the real discount, a general figure online may be out of date.
Compare feed-in offers
SA feed-in rates are set by retailers, not a state minimum, so comparing plans can be worth real money.
Check the timing
The federal schemes step down over time, with the battery rebate reducing every six months, so when you buy matters.
Lean on self-consumption
Because SA has high power prices and modest feed-in rates, using or storing your own solar usually beats exporting it.
SA solar rebates FAQ
Is there a solar rebate in SA?
The main support for solar panels is a federal scheme that reduces the upfront cost, applied by your installer as a discount. South Australia does not run its own state rebate for solar panels. For home batteries, a federal scheme reduces the cost by around a third, as SA's own Home Battery Scheme has closed. Some City of Adelaide council incentives may apply for eligible residents.
What battery support is available in SA?
Battery support in SA is the federal Cheaper Home Batteries scheme, which reduces the upfront cost by roughly a third of an eligible battery, applied as a point-of-sale discount with no income or property-value test. The value steps down over time, reducing every six months from 1 May 2026. SA's own Home Battery Scheme has closed, and many households also join a retailer Virtual Power Plant for extra value.
Is the SA Home Battery Scheme still available?
No. South Australia's own Home Battery Scheme has closed to new applications and has not been replaced. Battery support now comes through the federal scheme, applied as an upfront discount. Joining a retailer Virtual Power Plant is optional and can add value in return for letting the network draw on your battery at peak times.
What feed-in tariff will I get in SA?
South Australia does not set a state minimum feed-in tariff. Rates are set by retailers in a competitive market and vary between plans, so it is worth comparing. With SA's high power prices and modest feed-in rates, the bigger saving usually comes from using or storing your own solar rather than the credit for exporting it.
Do solar rebates change over time?
Yes. The federal schemes for both solar panels and batteries step down over time on a set schedule, with the battery rebate reducing every six months. Feed-in rates are set by retailers and change between plans. Because of this, a current quote is the most reliable guide to the support that applies when you buy.
