Cheaper Home Batteries Program
Launching 1st July 2025
The NSW Government is launching a new Federal solar battery rebate From 1 July 2025, the program will provide around a 30% discount on the upfront cost of installing eligible small-scale battery systems. The discount will be based on the battery’s usable capacity and will gradually decrease until 2030.

Eligible battery systems
An eligible battery storage system must be in the range of 5 kWh to 100 kWh in nominal capacity. The nominal capacity is the maximum amount of energy a battery can store at full charge.
- The discount will be provided for up to 50 kWh of a battery system’s usable capacity.

Eligibility Requirements for the Battery Rebate
Discount for eligible battery systems
STC calculation
- The number of small-scale technology certificates (STCs) a battery system earns is based on its usable capacity—the amount of energy you can actually draw from it. Only the first 50 kWh of usable capacity qualify for STCs.
- The rebate rate (in STCs per kWh) steps down each year and, at an assumed STC market price of $40, equates roughly to the dollar values shown below:
| Year | 2025 | 2026 | 2027 | 2028 | 2029 | 2030 |
|---|---|---|---|---|---|---|
| Estimated value per kWh | $372 | $336 | $296 | $260 | $224 | $188 |
| STC factor | 9.3 | 8.4 | 7.4 | 6.5 | 5.6 | 4.7 |
- The estimated value per kWh is approximate and based on $40 per STC for a battery installed in the year. This could vary over time in line with reviews of whether the discount remains appropriate.
Number of battery systems
- Each premises may claim STCs for one eligible battery installation under this federal program.
- Additional rebates or incentives are available for batteries in nsw.
Installing an eligible battery system
Accreditation of battery installers
- Installation (or on-site supervision) must be carried out by a Solar Accreditation Australia (SAA) battery installer.
Supervision of the installation
- If the installer isn’t directly performing every task, they must still be physically present on-site to oversee the work.
Installation date
- Only systems installed on or after 1 July 2025 can claim STCs. A system is deemed “installed” when a signed certificate of electrical compliance (or equivalent) confirms it meets all relevant state/territory safety regulations.
Installing a battery system with solar PV
- The battery must be paired with an existing or new solar PV array at the same premises.
Battery system installation standard
- All installations must comply with the industry’s Best Practice Guide: Battery Storage Equipment.
