Solar and batteries in Adelaide: prices, SA rebates and free midday power
The short answer
Power on the SA Power Networks default offer costs about 42c a kWh, the highest standard price of any state, and each kW of panels in Adelaide makes about 1,500 kWh a year, so solar you use yourself is worth a lot here. For an Adelaide home, budget about $4,500 to $8,500 for 6.6 kW of solar, or about $13,500 to $23,000 with a 15 kWh battery, installed after the federal rebate (October 2026: current installer prices on Homerise and Adelaide market data).
How much does solar cost in Adelaide?
After the federal rebates, installed, GST included (October 2026):
| What you buy | Typical price |
|---|---|
| 6.6 kW solar | about $4,500 to $8,500 |
| 10 kW solar | about $8,000 to $11,500 |
| 13 kW solar | about $10,000 to $14,500 |
| 6.6 kW solar + 15 kWh battery | about $13,500 to $23,000 |
| 10 kW solar + 20 kWh battery | about $15,500 to $29,500 |
| Battery only, per kWh (with hybrid-ready solar) | about $700 to $850 |
These are ranges, not quotes. Adelaide is one of the lower-priced capitals for solar; the battery figures are national. A double-storey or tiled roof, three-phase supply or a new switchboard can each add up to about $1,200, and current offers can beat the range. How the prices break down: solar panel cost and solar battery cost.
What rebates can Adelaide homes get?
Adelaide is in STC zone 3, so the federal solar rebate is about $1,665 on a 6.6 kW system, and the federal battery rebate about $3,663 on a 15 kWh battery, if installed now; both fall from 1 January 2027. They're already taken off the prices above. South Australia adds one program open to homeowners: SA REPS battery VPP incentive (via retailers and providers). Every program, who qualifies and how to claim it: solar and battery rebates in South Australia.
Some retailers and providers also pay an incentive for connecting a battery to an approved virtual power plant. Each sets its own amount, so it isn't in your Homerise price; compare the whole VPP offer, including how often your battery is used and any fees. More: virtual power plants.
On the old 44c feed-in tariff? The Premium feed-in tariff (44c) runs until 30 June 2028. For systems applied for before 30 September 2011. Installing a battery, or increasing the approved panel or inverter capacity, ends the premium tariff. Read adding a battery to existing solar before you change anything.
How much power does solar make in Adelaide?
Each kW of panels in Adelaide makes about 1,500 kWh a year: about 185 kWh a month in January and about 70 in June (PVWatts, panels facing north at 20°). A 6.6 kW system makes about 10,000 kWh a year. Summer is strong and winter is weak (about 38% of the best month), so a system that covers a winter evening produces far more than you can use in summer; that surplus is what a battery or a midday-heavy routine soaks up.
What does power cost in Adelaide?
On the SA Power Networks default market offer for 2026-27, power costs about 42c a kWh plus about $1.80 a day in supply charges, the highest standard usage price of any state. The feed-in tariff we use for SA is about 3c (check your own plan's), so each kWh of solar you use yourself is worth about 14 times one you export. With the highest usage price, a battery or more daytime use saves more per kWh in Adelaide than on any other state's standard price. Enter your own rates in the savings calculator.
Free midday power in Adelaide: the Solar Sharer Offer
Larger retailers in South Australia offer a plan with three free hours of power a day, 12pm to 3pm, up to 24 kWh. You need a smart meter, not solar. A battery can top up for free on cloudy winter days; without a battery, the free hours suit hot water, the pool pump and an electric car. Rates outside the free hours can be higher than your current plan's, so compare the whole plan before switching. More: the Solar Sharer Offer.
