Solar prices in Adelaide by system size
Installed prices are before rebates. The federal STC rebate is worked out at Adelaide's own STC zone (zone 3, postcode 5000) and comes off at the point of sale.
| System | Panels | Installed, before rebates | Federal STC rebate | After STC rebate |
|---|---|---|---|---|
| 6.6 kW | about 15 | $6,900-$9,200 | 45 STCs, about $1,784 | $5,116-$7,416 |
| 10 kW | about 23 | $10,500-$13,900 | 69 STCs, about $2,736 | $7,764-$11,164 |
| 13.2 kW | about 30 | $13,900-$18,300 | 91 STCs, about $3,608 | $10,292-$14,692 |
STCs valued at $39.65 each, the price used across this site, verified 13 July 2026. Zone from the Clean Energy Regulator's postcode zone table. Panel counts assume the 440 W panels the size pages use. How the installed bands are built is on solar panel installation cost.
What a fair Adelaide quote looks like
We don't sell packages or specials, so there is no Adelaide deal to advertise here. The low end of each band is budget panels and a budget inverter; the high end is premium brands and more complex roofs. A quote well under the low end usually leaves something out, such as a switchboard upgrade, tile work, network fees or a smaller inverter. Ask for every item in writing, with the STC rebate shown as its own line, using the solar quote checklist.
Is the solar rebate dropping in 2027?
Yes. The STC rebate is calculated from deeming years, which fall from 5 to 4 on 1 January 2027. A 6.6 kW system in Adelaide earns 45 certificates (about $1,784) if it is installed in 2026, and 36 certificates (about $1,427) from 1 January 2027: about $357 less at today's certificate price. The federal battery discount also steps down on 1 January 2027; see the Cheaper Home Batteries page for the schedule.
What's different about solar in Adelaide
South Australia has no state solar rebate open to every household, and its Home Battery Scheme closed in 2022, so Adelaide installs rely on the federal STC and battery discounts. The state's REPS virtual power plant incentive is limited to priority-group households for the rest of 2026, with general funding expected back in 2027.

Common questions about solar in Adelaide
How much do solar panels cost in Adelaide?
A 6.6 kW system in Adelaide costs about $6,900-$9,200 installed, before rebates. The federal STC rebate takes about $1,784 off (45 certificates at $39.65 in STC zone 3), leaving $5,116-$7,416. Figures verified 13 July 2026.
Which solar installer is best in Adelaide?
There is no single best installer in Adelaide, and we do not rank them. We match you with one installer that works your postcode, after checking its ABN and its Solar Accreditation Australia (SAA) accreditation. Our Adelaide directory lists the 20 solar companies registered nearby, with ABN status and years trading and no scores.
Are solar rebates dropping in 2027?
Yes. The STC rebate is based on deeming years, which fall from 5 to 4 on 1 January 2027. A 6.6 kW system in Adelaide earns 45 certificates if installed in 2026 and 36 from 1 January 2027, about $357 less at today's certificate price. The federal battery discount also steps down on 1 January 2027.
How long does solar installation take in Adelaide?
The install itself is usually one day on site. From signing the quote, expect around 4 to 6 weeks, most of it waiting for the network operator's connection approval and the installer's schedule. Ask for both dates on the quote.
What's the best feed-in tariff in Adelaide?
In the AER plan data retrieved 29 October 2026, the highest generally available flat offer in SA was EnergyAustralia at 8c/kWh for the first 10 kWh a day, then 3c. Rates change often, and the best plan depends on what you pay for the power you import, so compare the whole plan, not just the feed-in rate.
Is 10 kW solar enough to run a house?
In total energy, usually: a 10 kW system produces about 40 kWh on an average day (national average; Adelaide averages about 4.6 peak sun hours a day). Compare that with the daily usage on your power bill. The gap is timing: panels produce in the middle of the day, so without a battery you still buy power in the evening.
Do solar panels work well in Adelaide's climate?
Yes. Adelaide averages about 4.6 peak sun hours a day. Output scales with sun hours, so the same system produces less in a lower-sun city, but the STC rebate is set by your postcode's zone rating, not by what the system actually produces.
What is the average cost of a solar and battery package in Adelaide?
A 6.6 kW solar system plus a 13.5 kWh battery in Adelaide costs about $21,006-$25,406 installed, before rebates. The federal STC rebate and the federal Cheaper Home Batteries Program take about $5,392 off between them, leaving about $15,614-$20,014. SA's previous state battery scheme closed in 2022, so this is federal support only. Figures verified 13 July 2026.
