Solar Rebates & Incentives in Australia: How to Maximise Your Savings in 2024

Solar Rebates & Incentives in Australia: How to Maximise Your Savings

Installing solar panels on your home is one of the smartest financial decisions an Australian homeowner can make — but the upfront cost still gives many people pause. Fortunately, a combination of federal and state government incentives can significantly reduce what you pay out of pocket. Understanding how these schemes work puts you in a much stronger position when comparing quotes and planning your installation.

The Federal Government: Small-scale Technology Certificates (STCs)

The backbone of Australia's solar incentive system is the Small-scale Renewable Energy Scheme (SRES), administered under the Clean Energy Regulator. When you install an eligible solar panel system, you generate a number of Small-scale Technology Certificates (STCs) based on:

• The size of your system (in kilowatts)
• Your location's solar zone rating
• The number of years remaining until the scheme closes in 2030

In practice, most installers will deduct the STC value directly from your invoice — so you never handle the certificates yourself. For a typical 6.6 kW system installed in Sydney in 2024, STCs can reduce your upfront cost by approximately $2,800 to $3,500 AUD, depending on the current STC spot price.

It is worth noting that the value of STCs decreases each year as 2030 approaches, so acting sooner rather than later does make a financial difference.

State and Territory Rebates

Beyond the federal scheme, several states offer their own rebates and interest-free loan programmes. The landscape changes regularly, so always verify current eligibility criteria directly with the relevant authority.

State / Territory	Key Incentive	Approximate Benefit
Victoria	Solar Homes Programme rebate	Up to $1,400 AUD
Queensland	Battery Booster rebate (batteries)	Up to $3,000 AUD
South Australia	Home Battery Scheme subsidy	Up to $2,000 AUD
New South Wales	Empowering Homes interest-free loan	Up to $14,000 AUD
ACT	Sustainable Household Scheme loan	Up to $15,000 AUD
Western Australia	Distributed Energy Buyback Scheme	Feed-in tariff benefit

Note: availability and amounts are subject to change. Some programmes have waitlists or income eligibility requirements.

Feed-in Tariffs (FiTs)

Once your system is installed, you can earn credits on your electricity bill for any surplus energy exported to the grid. Feed-in tariff rates vary considerably by state and retailer:

• Victoria: Minimum FiT set by the Essential Services Commission (currently around 4.9 cents per kWh for a single-rate tariff)
• Queensland, NSW, SA: Rates are retailer-determined, typically ranging from 5 to 10 cents per kWh
• Western Australia: Synergy's Distributed Energy Buyback Scheme offers time-varying rates

While FiTs alone should not be the primary reason to go solar, they do improve the long-term return on your investment.

Battery Storage Incentives

With electricity prices remaining high, battery storage is growing in popularity. Several states specifically target battery rebates, separate from solar panel incentives:

• South Australia's Home Battery Scheme has supported thousands of households with subsidised battery installations
• Queensland's Battery Booster programme targets low-to-middle income households
• Victoria has extended its Solar Homes Programme to include battery rebates for eligible households

Adding a battery to a solar system can further reduce grid dependence and improve bill savings, particularly in households with evening-heavy energy use.

What You Need to Qualify

To access STCs and most state rebates, your installation must meet specific requirements:

• Solar panels and inverters must be listed on the Clean Energy Council (CEC) approved products list
• The system must be installed by a CEC-accredited installer
• System capacity is generally capped (commonly at 100 kW for residential)
• Some state rebates apply income or property value tests

Getting the Most from Available Incentives

A few practical steps will help you capture the full value of available rebates:

• Obtain at least three written quotes that clearly show the STC discount applied
• Check your state government's energy website for current programme availability before signing any contract
• Confirm that battery rebates can be stacked with solar rebates in your state
• Keep all documentation — you may need proof of installation for tax or rebate purposes

Australia's incentive environment remains genuinely favourable for homeowners considering solar, but navigating the various schemes is easier when you work with a qualified professional. Choosing a CEC-accredited installer ensures your system meets the standards required to access every incentive available to you — and gives you confidence the job is done properly from day one.
