Federal Battery Rebate for Queensland Homes
How much the Cheaper Home Batteries discount takes off a battery in Moreton Bay and the Sunshine Coast, who qualifies, and when it steps down.
How it works
The federal Cheaper Home Batteries discount
The discount is paid through small-scale technology certificates (STCs), the same system that discounts rooftop solar. Your accredited installer creates the certificates and takes their value straight off your price.
We size the battery
The discount is based on the battery's usable kWh, so we size it to your evening use, not the biggest box available.
Certificates are calculated
Usable kWh × the current STC factor, with tiers above 14 kWh, gives the number of certificates.
Discount on your invoice
The certificate value comes off your quote. You don't lodge a claim or wait for a refund.
Since 1 May 2026
Discount tiers by battery size
Only the first 50 kWh of usable capacity earns certificates, and the rate tapers above 14 kWh. Batteries up to 100 kWh remain eligible.
| Usable capacity | Share of the STC factor | Certificates per kWh (May–Dec 2026) |
|---|---|---|
| 0–14 kWh | 100% | 6.8 |
| 14–28 kWh | 60% | 4.08 |
| 28–50 kWh | 15% | 1.02 |
| Above 50 kWh | No further discount | 0 |
What it's worth
Example discounts
Dollar values assume certificates trade at $37–$40 each, the typical range in 2026.
| Battery (usable) | Certificates | Discount if installed May–Dec 2026 | Discount if installed Jan–Jun 2027 |
|---|---|---|---|
| 10 kWh | 68 | $2,500–$2,700 | $2,100–$2,300 |
| 13.5 kWh | 92 | $3,400–$3,700 | $2,800–$3,100 |
| 20 kWh | 120 | $4,400–$4,800 | $3,700–$4,000 |
| 40 kWh | 165 | $6,100–$6,600 | $5,100–$5,500 |
The discount drops every six months. The STC factor was 8.4 in January–April 2026, is 6.8 for May–December 2026, and falls to 5.7 in January–June 2027 and 5.2 in July–December 2027. The program is also due to change again from 1 January 2027, so we confirm the current figures on every quote.
Eligibility
Who qualifies
- A home or small business with rooftop solar, or solar installed at the same time
- A battery on the Clean Energy Council approved product list
- Installed by an accredited installer (SEBSS is CEC-accredited, Licence 73850)
- Usable capacity up to 100 kWh (only the first 50 kWh earns certificates)
- Adding a battery to an existing solar system qualifies
- VPP-capable hardware is recommended; joining a VPP is your choice
Is there a Queensland state battery rebate? Not at the moment. The Queensland Battery Booster closed in May 2024 once its funding was allocated, and no new state program has been announced. We check for new state schemes before every quote.
Our advice
Get the rebate without overbuying
Size to evening use
Because the discount tapers after 14 kWh, most homes get the best value from a battery matched to their after-sunset usage.
Check your solar can fill it
An older 5 kW system may not charge a large battery in winter. We model both before recommending a size.
Install before the step-down
A 10 kWh battery loses about $400 of discount when the factor drops in January 2027.
FAQ
Battery rebate questions
Do I need to apply for the battery rebate?
No. Your installer creates the certificates and takes their value off your invoice, so the discount appears on your quote.
How much is the battery rebate in Queensland?
For batteries installed between May and December 2026, a 10 kWh battery gets about $2,500–$2,700 off and a 20 kWh battery about $4,400–$4,800, depending on certificate prices.
Can I get the rebate if I already have solar?
Yes. Adding a battery to an existing solar system qualifies, as long as the battery is on the approved list and installed by an accredited installer.
Will the rebate be smaller in 2027?
Yes. The certificate factor falls from 6.8 to 5.7 per kWh in January 2027 and to 5.2 in July 2027, and the program is due to change again from 1 January 2027.
