Secure the Full Home Battery Rebate Before May 2026.

Australia’s Cheaper Home Batteries Program has made battery storage significantly more affordable for homeowners looking to maximise the value of their solar systems. By providing an upfront rebate on battery installations, the program has made the installation of a battery, more affordable, especially for us who are off the grid.
Introduced in July 2025 this tax payer funded battery rebate has seen enormous uptake; to the point that from 1 May 2026, the structure of the battery subsidy will change, reducing the value available for many installations. While the rebate will still exist, the amount available will decrease. For those already considering a battery, this means the coming weeks represent the last opportunity to secure the full rebate currently available.
How the Battery Subsidy Works
Much like the solar panel incentive, the battery rebate operates through the Small-scale Renewable Energy Scheme, which provides an upfront discount when installing eligible battery systems. The rebate is calculated based on the usable capacity of the battery system and is applied during installation through Small-scale Technology Certificates (STCs). This currently reduces the cost of a battery by around 25–30%, depending on the battery size.
The program is not limited to residential batteries, larger battery systems and off-grid installations are also eligible.
What Changes on 1 May 2026
Two key changes will take effect from May 2026.
1. The rebate per kilowatt-hour will decrease
Currently, the subsidy provides roughly $300 per kilowatt-hour of battery capacity for the initial portion of eligible systems. From May 2026, this will drop to approximately $244 per kilowatt-hour. While the rebate will still provide savings, the same battery installed after May will attract a smaller incentive than installations completed prior to May 1st 2026.
2. A tiered rebate structure will apply
In addition to the reduced rate, a new tiered structure will apply depending on battery size.
The rebate will apply at different levels depending on the system capacity:
0–14 kWh: 100% of the rebate value
14–28 kWh: approximately 60% of the rebate value
28–50 kWh: approximately 15% of the rebate value
Why has this structure changed you ask? In truth, when the tax payer funded scheme was rolled out in July 2025, it was realised very quickly that the volume of uptake would quickly exceed the allocated budget and therefore the parameters had to be adjusted, rapidly.
What This Means for Homeowners
For many homeowners, the rebate still represents thousands of dollars in savings. Even after May, battery installations will continue to benefit from government rebates.
However, the upcoming change means that installing a battery before the end of April may allow homeowners to access a larger subsidy for the exact same system.
Depending on battery size, the difference could amount to significant difference in savings.
This is especially important for larger battery systems and off-grid installations, where the subsidy can represent a significant portion of the total system cost.
Put simply, if you have already been considering adding battery storage to your home or property, this may be the final window to access the full rebate currently available.
Why More Australians Are Installing Batteries
Battery installations across Australia are increasing as homeowners look for ways to take control of their energy supply.
With a battery system, homeowners can:
Store excess solar energy generated during the day
Use stored energy in the evening when electricity prices are higher
Reduce reliance on the grid
Protect against rising energy costs
Improve energy independence for their home or property
For rural and lifestyle properties, batteries also make off-grid energy systems increasingly viable, allowing homes to operate independently from network infrastructure.
Is a battery installation right for you?
Many who know Paul, know he will tell it to you straight. Installing a battery is not always the best investment. Paul is focused on helping his customers design solar and battery systems that maximise both performance and long-term savings. This includes grid-connected battery systems, large battery installations, and fully off-grid energy systems.
