What Is the Solar Rebate in Queensland?
The main solar rebate in Queensland is the federal Small-scale Renewable Energy Scheme discount, commonly called the STC rebate. STCs, or Small-scale Technology Certificates, are certificates created when an eligible solar system is installed. In most cases, these certificates are assigned to the installer or retailer in exchange for an upfront discount on the cost of the system.
This means Queensland customers usually do not need to claim the solar rebate separately after installation. Instead, the estimated STC discount is normally shown in the solar quote.
- The STC discount applies to eligible solar PV systems.
- The system must meet product, design and installation requirements.
- The final discount can vary depending on system size, location, installation date and STC market value.
- The scheme reduces over time as it moves towards its scheduled end date.
- Battery discounts are handled separately through the federal Cheaper Home Batteries Program.
A tailored quote is the best way to understand what discount may apply to your home or business. If you are planning solar for a Queensland property, our team can help assess your roof, electricity usage and system goals before recommending a suitable setup.
How Does the Queensland Solar Rebate Work?
The QLD solar rebate usually works as an upfront STC discount on an eligible solar PV system. The number of STCs created depends on factors such as the system size, installation location and the remaining period of the scheme.
For example, a 6.6kW system and a 10kW system may attract different STC values because they are different sizes. The right system should still be based on your energy use and needs, not simply the largest rebate amount.
How the Rebate Process Works
- Property review: Your roof, usage, budget and long-term goals are reviewed.
- Solar quote: The estimated STC discount is included where eligible.
- Approved equipment: The system must use eligible solar panels, inverters and components.
- Accredited installation: The system must be designed and installed by appropriately accredited professionals.
- Solar generation: Your system generates solar power for use at the property, with long-term value depending on system size, self-consumption, tariffs and electricity habits.
Am I Eligible for the Queensland Solar Rebate?
Eligibility depends on the rebate pathway being claimed. For the federal STC solar discount, Queensland homes and businesses may be eligible when the solar PV system meets Small-scale Renewable Energy Scheme requirements.
Common eligibility factors include:
- The system is installed at an eligible Queensland property.
- The solar PV system is classified as a small-scale system.
- The panels, inverters and relevant components are approved for the scheme.
- The system is designed and installed by appropriately accredited professionals.
- The installation meets Australian standards and local electrical safety requirements.
- STCs are created within the required timeframe after installation.
Eligibility should be checked before installation, especially if you are upgrading, replacing panels, adding extra capacity, installing a battery or installing solar for a business site.

Is There a Rebate on Solar Batteries in QLD?
Queensland households, small businesses and community organisations may be able to access the federal Cheaper Home Batteries Program for eligible battery systems connected to new or existing solar PV systems.
This is separate from the old Queensland Battery Booster Program. The Queensland Battery Booster Program was a state battery rebate, but new conditional approval applications closed in 2024. In 2026, the main battery incentive for most Queensland customers is the federal Cheaper Home Batteries Program.
A battery can help store daytime solar for evening use, reduce reliance on grid electricity and improve how much of your own solar power you use. However, the right battery size depends on your energy use, solar output, inverter capacity, backup needs and budget.
For battery-specific advice, visit our solar battery storage page or ask our team about a solar and battery package.
QLD Federal Battery Rebate
The federal Cheaper Home Batteries Program supports eligible small-scale battery systems connected to new or existing solar PV systems. The program is available nationally, which means Queensland customers may be able to access the discount if the system meets the relevant requirements.
The discount is generally provided through solar and battery retailers or installers. Customers may also be able to claim directly through the REC Registry, but most households receive the benefit as an upfront discount through their quote.
The value can depend on usable battery capacity, installation date, STC settings, current certificate values and whether the system meets product and installation requirements.
- The battery must be connected to a new or existing solar PV system.
- The discount is based on the battery’s usable capacity.
- The battery and installation must meet program requirements.
- The level of support decreases over time until 2030.
- Bigger is not always better, as battery size should match the property’s solar output and energy usage.
Eligible battery systems
To qualify for the federal Cheaper Home Batteries Program in Queensland, a battery system needs to meet current scheme requirements. These requirements cover battery size, product approval, installation standards and whether the battery is connected to solar.
The program is designed for small-scale battery systems connected to new or existing solar PV systems. It can support households, small businesses and community organisations, but eligibility depends on the battery, installer, system design and installation date.
Minimum and maximum battery size
- An eligible battery storage system must generally be between 5 kilowatt-hours (kWh) and 100 kWh in nominal capacity. Nominal capacity is the maximum amount of energy the battery can store when fully charged.
- The discount is only provided for up to 50 kWh of usable capacity. Usable capacity is the amount of energy the home or business can actually draw from the battery.
- The program is intended to support small-scale residential, business and community battery systems.
- Electric vehicles are not eligible battery systems under this battery discount program.
Battery system composition
An eligible battery system may include a single battery unit or a modular battery setup connected to work as one battery system.
- A single battery unit may be eligible if it meets the program requirements.
- A system of modular battery cells may also be eligible if the modules are connected to operate as one battery system.
- Additional capacity added to an existing battery system may be eligible if the original battery system has not already received a discount under the program.
- The added capacity must generally be at least 5 kWh, and the total upgraded battery system must not exceed 100 kWh in nominal capacity.
- If an existing battery has already received a discount under the program, extra capacity added later would generally not be eligible for another discount.
Approved batteries and inverters
The battery system and inverter need to meet current product approval requirements. This generally means checking whether the battery and inverter are listed on the relevant Clean Energy Council approved product lists before installation.
This is one reason it is important to work with a solar and battery installer that checks product eligibility before quoting. Aus Energy Solar can help Queensland customers compare solar battery storage options based on system compatibility, stored energy needs, inverter capacity and future upgrade plans.
VPP capability
For an on-grid battery system, the battery generally needs to be capable of being coordinated through a virtual power plant, often shortened to VPP. This does not mean you must join a VPP.
- A VPP-capable battery can connect to the electricity grid and respond to signals from a third-party VPP operator, such as an energy retailer.
- This usually requires an ongoing internet connection.
- Consumers are not required to participate in a VPP to receive the battery discount.
- Off-grid battery systems are generally not required to be VPP-capable because they are not connected to the electricity grid.
Battery eligibility can change, so it is best to confirm the current requirements before installing. Our team can help you check whether a solar and battery package may suit your property, energy use and needs.
Discount for Eligible Battery Systems
The Cheaper Home Batteries Program discount is calculated through Small-scale Technology Certificates, usually called STCs. These certificates are linked to the eligible usable capacity of the battery system and the STC factor that applies at the time the battery is installed.
In plain English, this means the discount is not a fixed dollar amount for every battery. It can vary based on the battery size, usable capacity, installation date, certificate value and current program rules.
STC calculation
- The number of STCs a battery system can create is based on the battery’s eligible usable capacity.
- Usable capacity means the amount of energy that can be discharged from the battery and used by the home or small business.
- STCs are only provided for up to the first 50 kWh of usable battery capacity.
- The STC factor changes over time, so a battery installed later may receive a lower discount than the same battery installed earlier.
- The discount you receive is based on the STC factor that applies on the installation date.
Current STC factor changes
The Cheaper Home Batteries Program changed from 1 May 2026. Under the updated rules, the STC factor declines more often and the level of support also tapers for larger batteries.
| Period | Amended STC Factor |
|---|---|
| January to April 2026 | 8.4 |
| May to December 2026 | 6.8 |
| January to June 2027 | 5.7 |
| July to December 2027 | 5.2 |
| January to June 2028 | 4.6 |
| July to December 2028 | 4.1 |
| January to June 2029 | 3.6 |
| July to December 2029 | 3.1 |
| January to June 2030 | 2.6 |
| July to December 2030 | 2.1 |
How battery size affects the discount
The program can support battery installations up to 100 kWh in nominal capacity, but the level of support is not the same across every kilowatt-hour of capacity. Since 1 May 2026, the STC factor has been tapered based on the amount of capacity installed.
| Battery Capacity | Support Level | What It Means |
|---|---|---|
| 0 kWh to 14 kWh | 100% of the STC factor | The strongest support applies to the first 14 kWh of eligible capacity. |
| More than 14 kWh up to 28 kWh | 60% of the STC factor | Additional capacity above 14 kWh receives reduced support. |
| More than 28 kWh up to 50 kWh | 15% of the STC factor | Larger battery capacity receives a lower level of support. |
| More than 50 kWh | No STC support for capacity above 50 kWh | The battery system may be larger, but support is capped at eligible usable capacity up to 50 kWh. |
Why bigger is not always better
A larger battery can store more energy, but it may not always deliver better value. If the battery is too large for your solar output, inverter capacity or night-time usage, you may not use enough stored energy to justify the added cost.
For example, a household that uses most of its power during the day may need a different battery size to a household that uses more electricity at night. A home planning for EV charging, pool pumps or backup power may also need a different setup.

Number of battery systems
- A single battery system installation at a premises is generally eligible for support once under the program.
- Additional state or territory support may be available in some areas, but this depends on the rules of each scheme.
- Queensland customers should check whether any current state, retailer or finance support can be used with the federal battery discount.
- Eligibility should be checked before installation, especially if you already have solar, already have a battery, or plan to add capacity later.
