Queensland's Battery Booster closed in May 2024, so the state has no battery rebate of its own in 2026. What Queensland does have: the federal rebate in every postcode, strong sun, and high evening prices to dodge.
Your solar panels work hard all day. Then the sun goes down, your house switches to the grid, and you buy back power at the worst price of the day, right through the evening peak. A battery stores your own cheap daytime power for that window instead.
The catch used to be the upfront cost. The federal Cheaper Home Batteries Program changed that in 2025. It takes thousands off a battery at the point of install, in every Queensland postcode, with no income test.
Two things to know. Queensland's Battery Booster closed back in May 2024, so the federal rebate is the one that matters here. And the federal rebate now steps down every 6 months, so the amount you can claim is the highest it will be today.
Here is exactly what Queensland homes can claim in 2026, and how to see your number in 30 seconds.
Solar rebates in Queensland (2026)
Quick answer: in Queensland the federal STC rebate takes roughly $1,600 to $2,200 off a 6.6kW solar system in 2026, applied as an upfront discount. Queensland has no state cash rebate for solar in 2026 (the Battery Booster closed in May 2024), but high sun hours and top retailers paying up to 10c/kWh on export make the payback among the best in the country. For storage, the federal Cheaper Home Batteries rebate takes about $2,700 off a 10 kWh battery. Calculate your STC rebate below.
Estimate for a 6.6 kW system in STC Zone 2, at a 5-year deeming period (2026). The STC price moves with the market, so your installer applies the exact discount at signing.

What every QLD home gets (federal)
The federal Cheaper Home Batteries Program applies in every QLD postcode. A 10 kWh battery in Brisbane gets up to around $2,700 off at install. The exact figure depends on your battery's usable size and the current certificate price, so the check gives you your real number.
The rebate is paid per usable kWh and tapers as the battery gets bigger. Most home batteries sit in the top band. Bigger is not always better value once you pass about 14 kWh, which the sizing check accounts for.
The rate dropped on 1 May 2026 and now steps down every 6 months, not once a year. Plenty of older guides still quote the bigger 2025 number, and some still show Queensland's Battery Booster, which closed in May 2024. Treat any fixed dollar figure as a guide and confirm your own in the check.
The federal STC factor by install period. The rebate is a number of certificates (STCs) per usable kWh, and that per-kWh factor falls on a legislated timetable. This is the Clean Energy Regulator schedule, applied to the first 14 kWh of usable capacity, and it is the same in every state:
| Install period | STC factor per usable kWh | Change |
|---|---|---|
1 Jan to 30 Apr 2026 | 8.4 | none |
Most popular 1 May to 31 Dec 2026 (now) | 6.8 | down about 19% |
1 Jan to 30 Jun 2027 | 5.7 | down about 16% |
1 Jul to 31 Dec 2027 | 5.2 | down about 9% |
1 Jan to 30 Jun 2028 | 4.6 | down about 12% |
What that works out to in dollars, by battery size. Approximate federal discount at the current (1 May to 31 Dec 2026) rate, off the invoice. The same figures apply Australia-wide because the battery rebate is federal, not zone-rated. Your exact number depends on the certificate price on the day, and the 30-second check returns the live figure.
| Usable battery size | Approx. federal rebate now | After 1 Jan 2027 (est.) |
|---|---|---|
10 kWh | around $2,450 | around $2,050 |
Most popular 13.5 kWh (Powerwall-class) | around $3,300 | around $2,750 |
16 kWh | around $3,750 | around $3,150 |
24 kWh | around $4,950 | around $4,150 |
Figures are indicative and rounded, not a quote. The 14 to 28 kWh portion is subsidised at about 60% and 28 to 50 kWh at about 15%, which is why the per-kWh value tapers on the larger sizes.

Why Queensland has no state rebate now
Queensland ran a Battery Booster rebate in 2023 and early 2024. It closed to new applications in May 2024, more than a year before the federal program launched, and the state has not replaced it. So in 2026 the federal rebate is the only battery subsidy in Queensland.
That timing trips up a lot of older guides, which assume the state scheme closed when the federal one arrived. It did not. There was a gap, and Queensland has been federal-only on batteries ever since.
The maths still works. Queensland has strong sun and high evening prices, so a battery that shifts your daytime solar into the evening pays off through self-consumption. The check shows your federal number for your exact postcode.
Do you qualify?
Most Queensland homes do. You qualify for the federal rebate if you have solar (existing or new), install a battery between 5 and 100 kWh through an accredited installer, and pick a battery on the approved product list. There is no income test, and the battery must be VPP-capable, which most approved batteries already are.
Brisbane metro and regional centres like the Gold Coast, Sunshine Coast, Townsville and Cairns are all in. Regional Queensland can have longer grid connection times, so factor that in. The 30-second check confirms your postcode either way.
Worked example: 10 kWh battery in Brisbane
Brisbane home, existing 6.6 kW solar, adding a 10 kWh battery to cover the evening peak.
| Line item | Amount |
|---|---|
Battery installed (list price) | around $12,000 |
Most popular Federal rebate at invoice | up to around -$2,700 |
State top-up | $0 (no QLD scheme) |
Your net cost | around $9,300 |
First-year bill savings in Brisbane run about $1,100 to $1,600, helped by strong sun and high evening prices. That is roughly a 5 to 7 year payback, then stored power for the life of the battery.
Your home is not the example. The check uses your postcode, your bill and your roof, and returns your real after-rebate number.
Why waiting costs you
The rebate steps down every 6 months now, and the next cut lands on 1 January 2027. Waiting does not get you a better deal. It gets you a smaller rebate and another summer of full-price power bills.
Brisbane install lead times run 4 to 8 weeks, longer in regional QLD where grid connection can take extra time, so a signed contract by early November 2026 locks in today's rate. The check is the fastest way to see your number and whether you qualify.
