Solar panels in SA, the complete guide
South Australia has high sunshine and some of the highest electricity prices in the country, which together make rooftop solar one of the smartest investments a home here can make. This is a clear, no-jargon guide to going solar in SA: what it costs, the support available, and how to get a good install.

The short answer
Solar makes strong sense for most SA homes. High sunshine means panels generate well, a federal scheme reduces the upfront cost, and a separate federal scheme takes a sizeable chunk off a battery. With some of the highest power prices in the country, using your own solar saves you a lot. Feed-in rates are set by retailers and vary, so the real value comes from self-consumption and storage. The best way to know what solar would cost and save at your property is a quote.
Why solar works well in SA
South Australia is one of the best places in the country for rooftop solar, for two reasons: strong sunshine and high electricity prices. A solar system generates power in proportion to the sunlight that reaches it, and SA, Adelaide especially, gets plenty across a long, bright day for much of the year.
That means a solar system on an SA roof tends to generate strongly and consistently. More generation means more of your daytime power coming from your own roof rather than the grid, and more surplus to either store in a battery or export. Because SA has some of the highest grid electricity prices in the country, every unit you generate and use yourself is worth more, which is what makes solar such a sensible choice across the state.
What solar costs in SA
There is no single price for solar, because it depends on the size of the system and your home. But the figures below give a realistic guide based on current SA pricing.
Cost ranges are indicative, based on current SA market data, checked May 2026. They are not a quote. Your actual price depends on the system and your home.
The single most useful number is the one from a quote for your own roof. A quote accounts for your home, your power use and the system that suits you, and applies the federal support at the current rate.
Solar support in SA
Solar in SA is supported mainly through federal schemes, one for panels and one for batteries. Here is the plain-English version, with more detail on the dedicated rebates guide.
The federal scheme
The main support that lowers the upfront cost of solar panels is a national scheme. It works through certificates that an eligible system creates, and your installer applies their value as a discount on your price. It applies in SA as it does nationally, and it steps down over time.
Battery support
A separate federal scheme reduces the upfront cost of an eligible home battery, broadly around a third of the cost, applied as an upfront discount. South Australia's own Home Battery Scheme has closed, so the federal scheme is the battery support to know about, along with retailer Virtual Power Plant offers.
For feed-in tariffs, South Australia does not set a state minimum. Rates are set by retailers in a competitive market and vary between plans, so it is worth comparing. The rebates guide covers all of this in detail, including how it changes over time.

SA solar FAQ
How much do solar panels cost in SA?
As a rough guide, a popular mid-sized home solar system in SA is broadly in the region of $5,000 to $7,000 after the federal support is applied. Larger systems cost more. The price depends on system size, the equipment and your roof, so a quote for your home gives the accurate figure.
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. For home batteries, a federal scheme reduces the cost by around a third, as South Australia's own battery scheme has closed. Feed-in rates are set by retailers. The rebates guide covers all of this in detail.
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 worth more than power exported in the middle of the day. This rewards using or storing your own solar during daylight hours rather than exporting it cheaply.
Is solar worth it in SA?
For most SA homes, yes. Strong sunshine means panels generate well, the federal support reduces the upfront cost, and you save by using your own power instead of buying from the grid. How quickly it pays back depends on your home and power use, which a quote will show.
Should I add a battery to my solar system?
South Australia is a strong state for batteries. With high power prices and modest feed-in rates, storing your solar to use in the evening is often worth more than exporting it, and a federal scheme reduces the upfront cost by around a third. The batteries guide covers whether one suits your home.
