Solar Battery Rebates Are Falling – Plan Before January
Australia's solar battery discount is set to decrease in January 2027. Learn about the changes, eligibility requirements, and how to plan your installation.
Solar Battery Rebates Are Set to Fall – Plan Your Installation Before January
Thinking about installing a solar battery at home? Now is a good time to review your options, as Australia's Cheaper Home Batteries Program is scheduled for another discount reduction from January.
For homeowners considering battery storage, this change could affect the upfront discount available on eligible installations. The program isn't ending in January, but the scheduled reduction makes it worthwhile to understand the changes and plans.
What's Changing from January?
The Australian Government has introduced more frequent reductions to the Small-scale Technology Certificate (STC) factor used to calculate the discount for eligible home battery installations.
| Installation period | STC factor |
|---|---|
| Current settings | 6.8 |
| From January | 5.7 |
The STC factor is scheduled to decrease by approximately 16%. However, this does not mean every homeowner's final dollar discount will fall by exactly the same percentage. The amount depends on factors including usable battery capacity and the value of STCs.

Why Plan Your Installation Early?
If a solar battery is already on your plans, getting started early gives you time to compare products, review quotes, and arrange installation.
Leaving everything until the final weeks can make it harder to secure your preferred battery or installation date.
Before committing, ask your installer to confirm:
- Whether your chosen battery meets program requirements.
- The estimated discount is under the current settings.
- The total installed cost after the discount.
- Whether installation and the required certification can be completed before January.
Important: Booking an installation or paying a deposit does not guarantee the current discount. Confirm the applicable installation and certification requirements with your installer.
Is a Solar Battery Right for Your Home?
A solar battery stores surplus electricity generated by your rooftop solar panels, so you can use it later, including in the evening when solar production falls.
Depending on your household's energy use and system design, battery storage may help you:
- Use more of your own solar electricity.
- Reduce reliance on grid electricity.
- Store surplus daytime generation for later use.
- Access backup power if the system is designed and configured to provide it.
The actual benefits depend on your energy consumption, battery capacity, installation cost, and electricity plan. A discount alone doesn't guarantee a worthwhile investment.
How to Choose the Right Battery
Before choosing a system, look beyond the advertised rebate.
1. Review your electricity usage.
Understand when your household consumes the most electricity and how much surplus solar energy you have.
2. Compare battery capacity.
Choose a system that suits your needs rather than assuming a larger battery will always deliver greater savings.
3. Check compatibility.
Your existing solar panels, inverter, and electrical setup may affect which batteries are suitable.
4. Compare complete quotes.
Review the installed price, discount, warranty, and realistic savings estimates.
5. Confirm the timeline.
If you're aiming to install before January, ask for a realistic installation and certification date.
What If You Install After January?
The program is scheduled to continue, but the STC factor will be lower. Further reductions are also planned under the current program settings.
This means eligible homeowners may still receive support after January, although the discount calculation will change.
There's no need to assume January is the final opportunity to install a battery. Instead, compare the likely discount with the total installed price, expected energy savings, and the timing that works for your household.
Conclusion: Plan, Choose Wisely
Australia's solar battery discount is scheduled to decrease from January, making the coming months' worth considering for homeowners already planning an installation.
If you want to target the current settings, start comparing eligible battery systems, request detailed quotes, and confirm whether your installation can realistically be completed before the deadline.
Most importantly, don't let the deadline be your only deciding factor. The right solar battery should suit your household's energy needs, work with your existing solar system, and offer value beyond the upfront discount.
Start planning early, compare your options carefully, and choose a solar battery that makes sense for your home.
