Save $2,106*+ when you install solar in South Australia.
The Australian Federal Government provides substantial rebates when you choose to install a solar PV system at your property. The rebate amount is based on the size of the system purchased and is deducted from the upfront cost of the solar system by your chosen solar provider.
In 2025 you can expect a $2,106* or more reduction for a 6.6kW system, a common size for SA homes.
The City of Adelaide also offers an additional rebate (up to $5,000) to landlords and concession card holders.
The amount of STC’s you receive are affected by two main variables - Location & System Size.
Location - The Federal Government splits all of Australia’s postcodes into 4 categories: Zone 1, Zone 2, Zone 3 and Zone 4.
If you reside in Zone 1, you’ll receive a greater rebate than someone that lives in Zone 2, who will receive a bigger rebate than someone in Zone 3 and so on. Zones are determined by the number of sunlight hours you receive in the location you are having your Solar PV System installed.
System Size - The other variable in determining the value of your rebate and amount of STC’s received, is the Solar PV System’s size. The larger the Solar PV System, the more power it will generate and the more STC’s and rebate amount you will be entitled to.
Under the Australian Government’s Small-Scale Renewable Energy Scheme (SRES), homeowners are entitled to a given number of STCs dependent on the system size, where the system is installed and which year the system is installed.
The scheme can be claimed on multiple properties. The rebate is claimed by the installer of your system and passed on as a point of sale discount.
STCs are a traded like shares and their worth fluctuates depending on the amount of installations occurring that year. More installs than expected and the worth depreciates. STCs are currently valued at around $39 but have been as low as $17, so now is definitely a good time to install.
Here’s the short answer to a pretty complicated question.
The solar panels that go on your roof are made up of a collection of smaller ‘cells.’ These cells are made up of layers of silicon.
When light particles from the sun hit a cell they knock electrons lose from the silicon. This results in a charge being generate that your solar system can then capture and use to power your home.
The incentives, rebates and finance options currently available in South Australia include:
The Federal STC Incentive
