1300 138 591Solar and battery rebates step down on 1 January 2027

See what you can claim
Pick what you're planning and where you live. We'll show the federal rebates on that system, what they drop to on 1 January 2027, and the Nexa price with them already taken off.
1. What are you planning?
No solar at all? A battery has to be paired with solar to get the discount, so choose Solar and a battery.
Type of upgrade
Adding panels claims on the new panels only. A full replacement (new panels and inverter) claims on the whole new system. Swapping some panels on an existing system can't claim.
2. System size
Adding a battery as well?
3. Where do you live?
Rebates if installed in 2026
$0
Rebate figures are estimates. They assume certificates trade at about $38 each and use a typical zone rating for your state, so northern and inland postcodes can claim a little more. The exact amount depends on your postcode, the equipment and the certificate price at the time, and is shown on your quote. Rebates are set by the install date, not the date you sign.
Rebates by system type
Every Nexa price already has the federal discounts taken off. Here is what applies to each type of system.
Solar for the first time
Small-scale technology certificates (STCs) reduce the price of solar systems up to 100kW. In South East Queensland a 6.6kW system earns about $1,710 for installs in 2026.
Adding a battery
The Cheaper Home Batteries discount reduces the price of an eligible battery from 5kWh to 100kWh, for homes, businesses and community organisations. A 10kWh battery earns about $2,580 for installs in 2026.
Solar and a battery together
You get both: STCs on the solar and the battery discount on the battery.
Upgrading your solar
Adding new panels or replacing an old system can earn STCs on the new capacity. We check what applies to your system.
Adding an EV charger
There is no federal rebate on home EV chargers. Charging from your own solar is where the saving comes from.
State schemes
Western Australia’s Residential Battery Scheme offers up to $1,300 for Synergy customers and up to $3,800 for Horizon Power customers. New South Wales offers an incentive for batteries connected to a virtual power plant, and the amount varies.

The numbers behind the step-down
The STC deeming period falls from 5 years to 4. On a 6.6kW system in South East Queensland that is roughly $1,710 down to $1,370. On a 10kW system, roughly $2,620 down to $2,090.
The battery STC factor falls from 6.8 to 5.7. On a 10kWh battery that is roughly $2,580 down to $2,170.
The battery discount steps down again every January and July until 2030, and the solar rebate every January until the scheme ends in 2030.
Rebates are paid as certificates whose price moves daily (about $37 to $40). Your quote shows the exact amount.
Rebate questions
Do I need to sign before 31 December or be installed?
Installed. The rebate rate is set by the installation date, not the date you sign or pay a deposit.
Do I have to apply for the rebate myself?
No. The discount is taken off your price at the point of sale. Nexa handles the certificates.
Can I get a rebate on a battery for my existing solar?
Yes. The Cheaper Home Batteries discount applies to eligible batteries added to existing solar.
Does a battery take my home off the grid?
No. A battery stores your solar for the evening, but your home stays connected. Backup in a blackout depends on the equipment and how it is set up.
Are there Queensland state rebates?
Not for home solar or batteries at the time of writing (November 2026). Queensland’s Battery Booster closed in 2024. The federal discounts still apply.
