What is the Cheaper Home Batteries Program?
The Cheaper Home Batteries program is the Australian Government's $7.2 billion solar battery rebate initiative (expanded from $2.3B in December 2025). It provides approximately 30% off eligible battery systems (5–100 kWh) for households, businesses and community organisations when installed by a SAA-accredited installer with a CEC-approved battery.
Since 1 May 2026 the program has used tiered rebates. The first 14 kWh receives 100% of the STC factor, 14 to 28 kWh receives 60%, and 28 to 50 kWh receives just 15%. The STC factor itself steps down on 1 January 2027 and every six months after that, so installing sooner secures a larger discount.
The rebate works as a point-of-sale discount applied directly to your quote. All CEC-approved batteries from major brands like Tesla, BYD and Sungrow are eligible, and the federal rebate is stackable with state programs for maximum savings.
The program is moving fast. The Clean Energy Regulator has already supported over 184,600 installations and projects up to 520,000 home batteries delivering 12 GWh of combined storage capacity by end of 2026. That growth is driven entirely by this scheme, which means demand on installers is high. Book early to install at the current STC factor before the next stepdown on 1 January 2027.

Eligible Batteries and Rebate Amounts
All CEC-approved battery systems (5–100 kWh) are eligible for the solar battery rebate. Here are popular options with estimated savings:
| Battery System | Capacity | Est. Rebate | After Rebate |
|---|---|---|---|
| Tesla Powerwall 3 | 13.5 kWh | $3,400 | $9,000-$12,500 |
| BYD Battery-Box Premium | 10.2-20.5 kWh | $2,500-$4,500 | $6,000-$11,500 |
| Sungrow SBR | 9.6-25.6 kWh | $2,400-$5,300 | $5,100-$12,700 |
| Enphase IQ Battery | 10.08 kWh | $2,500 | $5,900-$15,500 |
| Alpha ESS SMILE5 | 5.7-34.2 kWh | $1,400-$5,900 | $6,800-$11,000 |
*Prices are estimates and vary by installer, location, and installation complexity.
boltVPP-ready is a condition of the rebate
Every battery on this list must be VPP-capable to qualify for the rebate. That means once your battery is installed, you can immediately join a virtual power plant program and earn $300–$800/year by exporting stored energy during peak grid demand. The rebate cuts your upfront cost by ~30%, and a VPP turns the running cost into an income stream.
How the Rebate Decreases Over Time
The solar battery rebate is funded through Small-scale Technology Certificates (STCs). The STC factor determines how many certificates your battery creates per kWh. This factor declines every six months from May 2026, reducing the rebate over time.
| Period | STC Factor | Est. Rebate/kWh* |
|---|---|---|
| Jan – Apr 2026 | 8.4 | ~$311 |
| May – Dec 2026Now | 6.8 | ~$252 |
| Jan – Jun 2027 | 5.7 | ~$211 |
| Jul – Dec 2027 | 5.2 | ~$193 |
| Jan – Jun 2028 | 4.6 | ~$170 |
| Jul – Dec 2028 | 4.1 | ~$152 |
| 2029 – 2030 | 3.6 → 2.1 | ~$133 → ~$78 |
*Estimated rebate per kWh for the first 14 kWh, based on STC price of ~$37. Actual amount depends on market STC price at installation date. From May 2026, batteries over 14 kWh receive reduced rates (60% for 14–28 kWh, 15% for 28–50 kWh).
Federal + State: Stack Your Rebates

check_circleYou're Eligible If:
- checkYou have solar panels or are installing solar with the battery
- checkBattery is 5–100 kWh nominal capacity, CEC-approved
- checkInstalled by a SAA-accredited installer
- checkOn-grid batteries must be VPP-capable (able to participate in a virtual power plant)
- checkHouseholds, businesses and community organisations eligible
cancelNot Eligible:
- closeBattery-only systems without solar PV
- closeBatteries under 5 kWh or over 100 kWh nominal capacity
- closeDIY installations (must use SAA-accredited installer)
- closeNon-CEC-approved battery systems
- closePortable batteries and electric vehicles
What does "VPP-capable" mean? To qualify for the rebate, on-grid batteries must be able to participate in a virtual power plant. This means the battery can receive remote signals to export stored energy during grid demand events. All major brands (Tesla, BYD, Sungrow, Enphase, Alpha ESS) meet this requirement. Being VPP-capable doesn't mean you have to join a VPP, but it gives you the option to earn $300–$1,000+ per year from VPP participation on top of your regular savings.

Solar Battery Rebate FAQ
helpWhat is the solar battery rebate?
The solar battery rebate is officially called the "Cheaper Home Batteries" program. It provides approximately 30% off eligible battery storage systems (5-100 kWh) installed with new or existing solar PV. Households, businesses and community organisations are all eligible. The program runs through 2030 with $7.2 billion in funding. Since 1 May 2026 it uses tiered rates, with the STC factor stepping down again on 1 January 2027.
helpHow much can I save with the Cheaper Home Batteries program?
Tiered rates apply since 1 May 2026: the first 14 kWh receives 100% of the STC factor (around $252/kWh), 14 to 28 kWh receives 60% (around $151/kWh), and 28 to 50 kWh receives 15% (around $38/kWh). A 10 kWh battery saves around $2,520. A 13.5 kWh Tesla Powerwall 3 saves around $3,400. A 20 kWh battery saves around $4,430.
helpWho is eligible for the solar battery rebate?
Households, businesses and community organisations are all eligible. You need: a new or existing solar PV system (under 100 kW), a CEC-approved battery between 5-100 kWh nominal capacity, and installation by a SAA-accredited installer. On-grid batteries must be VPP-capable (able to participate in a virtual power plant). All major battery brands meet this requirement. There is no means test and the rebate is available per property.
helpCan I stack the federal battery rebate with state rebates?
Yes! The federal battery rebate can be combined with state programs. NSW residents can combine it with VPP PDRS incentives (up to $1,500). WA residents can stack with the state battery rebate ($1,300-$3,800). SA residents can add REPS VPP rebates (up to $2,050). Note: many state battery programs closed in 2024-2025.
helpWhen does the Cheaper Home Batteries program end?
The program runs through 2030 with $7.2 billion in funding (expanded from $2.3B in December 2025). Tiered rates have been in effect since 1 May 2026, and the STC factor steps down again on 1 January 2027 and every six months after that. Installing sooner secures a larger rebate.
helpHow do I apply for the solar battery rebate?
You do not need to apply directly. The rebate is applied as a point-of-sale discount through accredited installers. Your installer either offers an upfront reduction on the battery cost or a rebate after installation. Alternatively, you can claim the discount directly by creating and trading STCs through the REC Registry.
