Queensland has no state battery rebate in 2026, so the battery rebate Gold Coast homes can claim is the federal Cheaper Home Batteries Program. It takes money off a new battery through Small-scale Technology Certificates (STCs), and the current dollar figures sit on our solar and battery rebates page.
Solar Set installs solar and battery systems across the Gold Coast, Brisbane and Northern NSW from our Burleigh Heads base. This guide explains how the rebate is worked out, who can claim it, what changes on 1 January 2027, and the rules most quotes skip.
Updated October 2026. This guide replaces our earlier version, which was written before the 1 May 2026 changes.
Key Points
- The Queensland Battery Booster closed to new applications in May 2024, and we are not aware of a state scheme that replaced it. The federal Cheaper Home Batteries Program is the rebate Gold Coast homes can claim.
- Batteries installed from May to December 2026 earn 6.8 STCs per usable kWh. The factor drops to 5.7 for batteries installed from January to June 2027.
- The install date sets the rate, not the date you sign a contract.
- The full factor applies only to the first 14kWh of usable capacity, with 60 per cent applied from 14 to 28kWh and 15 per cent from 28 to 50kWh.
- Only one battery per meter can claim, and a later upgrade to a bigger battery at the same premises earns no certificates.
- The installer must be accredited by Solar Accreditation Australia (SAA) with a battery endorsement.
Is there a QLD state battery rebate in 2026?
No, Queensland has no state battery rebate open to new applicants in 2026. The Battery Booster closed to new applications in May 2024, and we are not aware of a state scheme that replaced it. Check the Queensland Government website for any new state program before you buy.
The rebate you can claim is the federal Cheaper Home Batteries Program, run by the Clean Energy Regulator (CER). STCs are certificates that an eligible solar or battery system creates under the federal Small-scale Renewable Energy Scheme.
Under the Clean Energy Regulator’s solar battery rules, the discount is set to work out to around 30 per cent of the upfront cost. You can assign your right to the certificates to your installer or a registered agent for an upfront discount, or you can create and sell the STCs yourself.
For you, that means the rebate usually appears as a discount line on your quote rather than a payment after the install.
How is the battery rebate amount worked out?
The rebate equals the number of STCs your battery creates multiplied by the price those certificates sell for. The certificate count comes from an STC factor multiplied by your battery’s usable capacity in kWh.
The factor steps down every six months on the CER’s published schedule, shown in the table below.
Here is a worked example from the rebate calculator we built for our rebates page. A battery with 16.6kWh of usable capacity, installed between May and December 2026, creates 105 STCs. That count matched an independent certificate agent’s calculator when we checked it on 10 September 2026.
The arithmetic is 14kWh at the full 6.8 factor, plus 2.6kWh at 60 per cent of it, rounded down to 105 STCs.
The certificate price moves with the market, so we keep the current dollar value on our rebates page rather than in this post. You get one place to check, with the figure kept up to date.
| Battery installed | STC factor per usable kWh |
|---|---|
| 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 does battery size change the rebate?
Bigger batteries earn more certificates, but each extra kWh earns less. The CER applies the factor in bands, and only the first 50kWh of usable capacity can create STCs at all.
Usable capacity is the energy you can actually draw from a battery. Nominal capacity is the total it holds on paper. The rebate is worked out on usable kWh, which is listed on the battery datasheet and is lower than the nominal figure.
Our Hollywell solar and battery system is a good example of reading the datasheet. It pairs 19.8kW of solar with a Sungrow SBH250 battery that has 25kWh of usable storage, so the first 14kWh earns the full factor and the next 11kWh earns 60 per cent of it.
Size your battery to your evening use, not to the rebate. You avoid paying for storage you may never use.
| Usable capacity band | Share of the factor applied |
|---|---|
| First 14kWh | 100 per cent |
| Above 14 up to 28kWh | 60 per cent |
| Above 28 up to 50kWh | 15 per cent |
| Above 50kWh | No STCs |
Who can claim the Cheaper Home Batteries Program?
Households and small businesses can claim it when the battery, the solar and the installer all meet the CER rules. There is no income test in the CER eligibility rules.
- The battery must be new and installed with a new or existing solar system of no more than 100kW, so you do need solar to claim.
- The battery must have a nominal capacity of 5 to 100kWh.
- The battery must be on the Clean Energy Council (CEC) approved battery list and comply with AS/NZS 5139:2019, the Australian and New Zealand safety standard for battery systems.
- The battery must be able to join a virtual power plant (VPP), which is a group of home batteries a provider coordinates to support the grid. You have no obligation to join one.
- Only one battery per premises can claim, which for a grid-connected home means one per NMI. Your NMI is the meter number printed on your power bill.
- The installer must be accredited by Solar Accreditation Australia (SAA) with a battery endorsement. Some quotes still say CEC-accredited, because installer accreditation was previously run under the Clean Energy Council name.
To check an installer, ask for their SAA accreditation number, then look it up on the SAA website and confirm the battery endorsement is listed. You get the discount and the peace of mind that the work meets the standard.
Apartments and rentals have extra rules. Our guides to strata solar rebates in QLD and solar rebates on a rental property cover who claims in each case.
Can you add a battery to your existing solar?
Yes, a battery retrofit can claim, but your inverter has to pass a test first. A hybrid inverter is one that runs both your panels and a battery.
If the new battery connects to your existing hybrid inverter, that inverter must be VPP-capable and on the CEC approved list now, or have been listed when your solar was commissioned. Our guide to how solar inverters work for Gold Coast homes explains the types.
A retrofit creates battery certificates only, because solar certificates come from new panels. You can add capacity to an existing battery only if it has never claimed STCs, the addition is at least 5kWh, and the total stays at or under 100kWh nominal.
The trap is the upgrade. If you claim on a small battery now and later move to a larger system at the same premises, you cannot claim STCs on the new battery. Sizing for where your household is heading protects your one claim at that meter.
Why does the install date matter, and should you wait?
The rebate is set by the date your battery is installed, not the date you sign a contract. The factor fell from 8.4 to 6.8 on 1 May 2026, and it drops to 5.7 on 1 January 2027.
In its release on the 1 May 2026 battery rebate changes, the CER confirmed the install date rule. It also told retailers to give accurate quotes and not promise installs they cannot complete on time.
Ask your installer for a realistic install date in writing, and ask what happens to your price if it slips past a step-down. If a salesperson pushes you to sign today because of the next date, get a second quote.
We would not rush a battery to beat a date, and we would not hold off for one either. Buy when a battery suits how your home uses power.
Is a battery worth it on the Gold Coast?
A battery pays its way when you use most of your power after dark. South East Queensland has no regulated minimum feed-in tariff, so the solar you export earns far less than the power you buy back at night.
Gold Coast and Brisbane homes sit on the Energex network, where your retailer’s market offer sets your feed-in rate. A battery stores that cheap daytime solar for the evening instead. A battery makes less sense if you plan to sell soon, because a rebated battery must stay at the property until the end of its warranty or the end of 2030, whichever is later.
Placement matters on the coast too. Batteries can cut back their output when they get too hot, so a shaded, ventilated spot is part of a good design. Our honest look at whether a solar battery is worth it on the Gold Coast works through the conditions in more detail.
Whatever size suits you, a clear quote shows you these lines:
- A clear quote shows the gross price of the battery and installation before any discount.
- A clear quote shows the number of STCs and the discount they take off, as a separate line.
- A clear quote shows the net price you pay after the discount.
- A clear quote shows the battery’s usable capacity in kWh, not just its nominal size.
- A clear quote shows the planned install date, so you know which factor applies.
Frequently Asked Questions
Is there a battery rebate in Queensland in 2026?
There is no state battery rebate open to new applicants in Queensland in 2026. The Battery Booster closed in May 2024, so the rebate Queensland homes can claim is the federal Cheaper Home Batteries Program, paid through STCs.
What if my installer cannot finish before 1 January 2027?
Your battery gets the lower factor of 5.7 if it is installed from 1 January 2027, even if you signed in 2026. The CER says rebates are set by the installation date, so get the install date and the terms for any price change in writing.
Is there an income test for the battery rebate?
No, the CER eligibility rules set no income test. Eligibility rests on the battery, the solar it pairs with, the installer and the premises.
Can I get the rebate again if I upgrade to a bigger battery later?
No, a later upgrade to a larger battery at the same premises earns no STCs. Only one battery per meter can claim, so size the first battery for where your household is heading.
Does my battery installer need CEC or SAA accreditation?
The CER requires Solar Accreditation Australia (SAA) accreditation with a battery endorsement. Some quotes still say CEC-accredited, so ask for the SAA number and check it on the SAA website.
Do I have to join a virtual power plant to get the battery rebate?
No, you do not have to join a VPP. The battery must be capable of joining one, but the CER sets no obligation to sign up.
