STC Rebate Explained | Eligibility, Application, and Savings
Switching to solar energy isn’t just about sustainability—it’s also about saving money upfront. The STC rebate, a key incentive under the Australian Government’s Small-scale Renewable Energy Scheme (SRES), helps reduce the upfront expenses of solar installations for households and small businesses. This rebate, based on Small-scale Technology Certificates (STCs), gives solar adopters the chance to lower their investment by leveraging the value of these certificates. But how does it work, and how much can you actually save? Let’s discuss the details to help you take advantage of such an amazing financial benefit!
What Is the STC Rebate?
The STC rebate is essentially a market-based subsidy program promoting renewable energy technologies in Australia. An STC represents one megawatt-hour (MWh) of renewable energy generated or displaced through an eligible small-scale energy system, such as solar panels or water heating systems. When consumers install these systems, they earn a number of STCs based on the system’s capacity and where it is installed. These STCs can then be sold to liable entities (such as energy retailers) in exchange for monetary benefits, which effectively reduces the upfront cost of the renewable energy system.
The broader aim of the rebate is to accelerate Australia’s transition to a cleaner energy future and meet the country’s emissions targets. For homeowners and businesses, the program represents an opportunity to invest in sustainable technologies and lower their carbon footprints while also saving money.
How Does It Work?
The STC rebate works by creating a financial incentive for small-scale renewable energy systems. When individuals install eligible systems such as solar panels or solar water heaters, they generate a certain number of STCs. The number is calculated based on:
1. The system’s capacity: Larger systems generate more certificates.
2. Location: Different zones across Australia yield varying amounts of STCs because sunlight exposure differs geographically.
3. Forecast lifespan: STCs are awarded based on the estimated energy generation or displacement over a number of years (e.g., 15 years).
After the STCs are generated, they can be sold in the Clean Energy Regulator’s STC market for cash or applied as a discount on the upfront purchase cost of the system. In most cases, solar retailers handle the paperwork and buy the STCs directly from the consumer, greatly simplifying the process.
How Much Can You Save with the STC Rebate?
The exact savings through the STC rebate depend on variables such as system size, geographic location, and market value of STCs at the time of installation. As of the latest market trends, STCs are valued at approximately $30–$40 per certificate. The number of STCs generated is calculated based on:
1. System Capacity: Larger systems (e.g., 6.6 kW or 10 kW solar setups) produce more certificates compared to smaller setups.
2. Solar Zone: Australia is divided into different solar zones, which estimate the system’s energy output based on local solar conditions. Zones with higher sunlight exposure generate more certificates.
3. Year of Installation: STCs are discounted annually as part of the scheme’s planned phase-out by 2030.
Let's say, a mid-sized solar PV system installed in a sunny area could generate hundreds of STCs over its expected lifespan, resulting in thousands of dollars in savings. On average, system owners can benefit from rebates ranging between $2,500 and $6,000 for a typical residential solar installation.
Who Is Eligible for STC Rebate?
Eligibility for claiming the STC rebate encompasses a broad spectrum of system owners, including residential households, small businesses, and community groups. Core eligibility criteria are set forth as follows:
✔ The renewable energy system must be solar panels, wind turbines, hydro systems, solar water heaters, or air source heat pumps.
✔ The system must be installed by a certified professional following the Australian standard.
✔ There are limitations based on system size and geographical location. Typically, systems up to 100 kW capacity are eligible.
✔ The system must be installed and certificates created within 12 months of the installation date.
✔ The system must not have been claimed under any other government rebates apart from SRES.
Furthermore, systems with higher energy efficiencies or located in high solar intensity zones typically yield more STCs, resulting in greater savings for eligible participants.
How to Apply for STC Rebate?
Applying for the STC rebate requires several administrative steps. Here’s an easy step-by-step to claim your small-scale renewable energy scheme rebate:
Step 1: System Installation. The renewable energy system must first be installed by a Clean Energy Council (CEC) accredited installer to guarantee compliance with regulations.
Step 2: System Registration. Post-installation, the system must be registered in the Renewable Energy Certificate (REC) Registry, managed by the Clean Energy Regulator. The installer typically helps with this process.
Step 3: Creation of STCs. Certificates are intentionally created based on the renewable energy system’s projected energy production. It involves inputting relevant data such as system capacity, installation date, and geographical data into the REC Registry.
Step 4: Assignment or Trading. System owners can assign their STC creation rights to installers or retailers in return for upfront discounts or sell them directly in the STC market. If they opt to trade directly, they must monitor market prices to optimize the sale.
Step 5: Complete Documentation. Collect and submit all requisite documentation, invoices, and compliance certificates. This will verify the system details and confirm that all installations meet necessary standards.
Step 6: Compliance Check. The Clean Energy Regulator conducts audits and compliance checks to make sure that all submitted claims are legitimate. Maintaining accurate records in case of any queries or inspections is advisable.
Step 7: Receipt of Rebate. Once the STCs are validated and traded or transferred, the financial rebate is either applied as a discount to your initial installation costs or provided as proceeds from STC sales.

FAQs
How do I claim my STC rebate?
Claiming your STC in solar rebate typically involves minimal effort on the homeowner’s part, as most solar installers manage the process on your behalf. When you purchase a solar system, the installer calculates the number of Small-scale Technology Certificates (STCs) your system is eligible for based on size, location, and installation date. They then apply the value of these certificates as an upfront discount on your installation quote. The installer claims and sells the STCs through the open market or via a clearing house.
Alternatively, if you choose to handle the process yourself, you must register with the Clean Energy Regulator as a Renewable Energy Certificate (REC) account holder, create the STCs, and manage their sale. This option can potentially yield a higher return but is significantly more time-consuming and complex, requiring a clear understanding of registration, documentation, and trading procedures.
What is the value of an STC?
The value of an STC (Small-scale Technology Certificate) is determined by supply and demand in the open market. Typically, STCs trade within a range of $35 to $40 per certificate. As of now, the average market price is approximately $38 per STC. The value may vary daily, as it is influenced by the overall demand from liable entities—usually electricity retailers—who are legally obligated under the Renewable Energy Target to purchase and surrender a certain number of STCs annually.
This obligation helps stabilize the STC market and maintain reasonable price levels. Homeowners benefit from this value through either an upfront rebate applied by their installer or direct sales if handling the process independently. It's important to monitor the market or consult your installer for the most accurate and up-to-date value.
How many STC for 6.6 kW?
The number of STCs generated by a 6.6 kW solar system depends on three main factors: the location of installation (which determines the solar zone), the date of installation, and the deeming period—the number of years remaining until the end of the scheme in 2030. For example, if you install a 6.6 kW system in Sydney, which falls into Zone 3, and the installation occurs in 2025 (giving it a 5-year deeming period), you could generate around 91 STCs.
At a current market price of $38 per STC, this would result in a total rebate of approximately $3,458, significantly reducing the upfront cost of your system. However, figures may vary based on system efficiency and precise geographic location, so it’s best to use an online STC calculator for a personalized estimate based on your conditions.
