How Much Solar Rebate Will I Get in Adelaide 2025?
By Solar Energy Adelaide | 2 March 2025
With Adelaide having some of the highest electricity costs in the world, it is not surprising that our beautiful State has led the charge in embracing a cheaper and more reliable alternative, solar power.
One of the major financial incentives for solar installation in Adelaide is the government solar rebate. These rebates can significantly reduce the upfront cost of your solar system, making your return on investment much faster.
In this article, we’ll explain how these rebates work, why they’re beneficial, and how you can take advantage of them to start saving on your energy bills.
What Is The Current Solar Energy Rebate In South Australia?
The primary solar rebate available to Adelaide residents comes in the form of Small-Scale Technology Certificates (STCs). This is a Federal Government solar incentive most commonly known as the STC Rebate.
These certificates are part of Australia’s Renewable Energy Target, designed to make renewable energy solutions more accessible and affordable for households and businesses.
Each STC represents a set amount of electricity generated by your solar system over its lifetime, and the number of STCs you receive depends on factors like:
- The size of your solar system
- The amount of energy it will produce
- Your geographical location (such as Adelaide)
How Much Solar Rebate Will I Be Able To Receive In Adelaide?
STCs act like a built-in discount on your solar system. The value of these certificates is deducted directly from the upfront cost of your installation. Typically, Adelaide homeowners can expect to save between $1,000 to $8,000 on a residential solar system through this rebate.
This deduction is automatically applied by your solar installer, so you don’t have to worry about complicated paperwork.
For example:
- Gross System Cost: $9,160
- STC Solar Rebate: -$2,520
- Net System Cost: $6,640
The above example shows how a solar system that initially costs $9,160 can be reduced to $6,640 with the STC rebate. This makes solar energy more affordable and helps you see a faster return on your investment.
Who is eligible for the solar rebate in South Australia?
To be eligible for the solar system rebate in Adelaide, both the inverter and the solar panels must be approved by the CEC (Clean Energy Council). In addition to this, the installation process has to be done by a certified CEC solar installer, such as Solar Energy Adelaide.

When Will The Solar System Rebate End?
The value of the STC rebate reduces each year on January 1st, as part of the government’s plan to phase out the incentive by 2030.
This means that the longer you wait, the fewer STCs you will receive, and the smaller your rebate will be.
Installing solar sooner rather than later allows you to lock in the current rebate value, maximising your savings.
Why Now is the Best Time to Install Solar Power in Adelaide
- Maximise Rebates: As the number of STCs you’re eligible for decreases each year, your rebate amount will continue to drop annually. By installing solar today, you can secure the highest possible rebate.
- Fast Return on Investment: The initial cost of your solar system is lower thanks to the rebate, meaning you’ll reach your break-even point faster. For someone buying a solar system in Adelaide, it generally takes 2-3 years for the system to have paid for itself with the savings you make. And the best bit, after this time your solar system will continue to save you money on electricity bills for the next 25 to 30 years.
- Energy Independence: With rising energy costs, going solar allows you to take control of your energy bills. Combined with solar battery storage, you can even store excess energy for use at night or during power outages.
Understanding the Process: How to Claim the Solar Rebate in South Australia?
One of the best aspects of the STC rebate is that it’s handled by your solar installer. Here’s how it works:
- Solar Consultation: Schedule a free consultation with a trusted solar provider in Adelaide, like Solar Energy Adelaide, to discuss your energy needs and receive a customised quote.
- Quote with Rebates Applied: Your solar provider will calculate the STC rebate based on your system’s size and location. The rebate amount will be deducted directly from your upfront costs, and the final price will be clearly outlined in your quote.
- Installation and Savings: Once you agree to the quote, your installer will handle the rebate paperwork and complete the installation, allowing you to start saving on your energy bills right away.
What About Free Solar Energy?
Solar financing allows you to make a simple switch to solar with $0 upfront…
Solar companies often advertise to customers that they could be eligible to get solar for free. But this can be misleading. You are still paying for the solar but the benefit is that you are not typically paying any more than what you already are paying on your electricity bills.
Let’s look at an example:
Jenny, an average South Australian homeowner, is paying $1,832 per year in electricity costs or $35 per week. She decides to install a 7.9 kW solar system and finances the system using a low-interest Green Loan over 72 months. Jenny’s new solar system saves her $1,855 a year on her power bill, and her loan repayments are only $29 per week—less than her old electricity costs!
By financing her solar system, Jenny eliminates her power bill, and she is paying less each week on her loan than she used to pay for electricity.
Financing means she can start enjoying the savings from day one without needing to pay upfront costs.
With a big push for renewable energy, solar financing was set up to assist more homeowners in being able to make the switch over to solar with low interest loans.
Solar financing is available through the banks as well as private institutions.
At Solar Energy Adelaide, we make this process easy by using the most trusted and best available financing options.
