What Are Solar Batteries?
Store excess solar energy and use it when you need it most
Solar batteries are energy storage systems designed to store excess electricity generated by solar panels during the day for use when the sun isn't shining. These batteries allow you to capture and store solar power, ensuring a continuous supply of energy even at night or on cloudy days.
How It Works
Solar Panels Generate
During daylight, your panels produce electricity from the sun.
Battery Stores Excess
Surplus energy flows into your battery instead of being wasted.
Power When You Need It
Battery auto-discharges to power your home when the sun goes down.
Full Control & Visibility
Manage charge, monitor usage, and optimise through your phone.

Federal Cheaper Home Batteries Program
The Australian Government's Cheaper Home Batteries Program, expanded to $7.2 billion through to 2030, provides an upfront point-of-sale discount on battery installations. Since 1 May 2026 the rebate is tiered: roughly $250/kWh for the first 14 kWh, $150/kWh for 14–28 kWh and $38/kWh for 28–50 kWh. For a typical 13 kWh battery, the discount is approximately $3,200. The rebate is already applied to quotes — no separate application needed.

Next Rebate Step-Down — 1 January 2027
The current STC factor of 6.8 applies to batteries installed until 31 December 2026. On 1 January 2027 it steps down to 5.7 (about 16% less rebate), then keeps reducing every six months until the program ends in 2030. The rebate is locked in on your installation date.
Eligibility
Save $600–$1,200/yr

Feed-in Tariff Optimisation
By storing excess solar energy in a battery instead of exporting it at low feed-in tariff rates, you can use that power during peak evening hours when electricity rates are highest. This tariff arbitrage can save you $600–$1,200 per year depending on your usage pattern and electricity plan.

VPP Earnings Potential
Many battery systems are VPP-compatible, meaning you can earn additional income by joining a Virtual Power Plant. VPPs allow your battery to export stored energy to the grid during peak demand periods, earning you credits on top of your regular bill savings.
Eligibility
Next Federal Battery Rebate Change — 1 January 2027
Since 1 May 2026 the Cheaper Home Batteries rebate is tiered by battery size (~$250/kWh for the first 14 kWh, ~$150/kWh for 14–28 kWh, ~$38/kWh for 28–50 kWh). On 1 January 2027 the STC factor steps down from 6.8 to 5.7, and it reduces every six months after that until 2030.
