Support is delivered through Small-scale Technology Certificates (STCs) worth about $252 per usable kWh in 2026. Since 1 May 2026, larger batteries earn a tiered rate:
| Usable capacity | Support rate | Typical value |
|---|---|---|
| 0 – 14 kWh | 100% of STC factor | ≈ $252 / kWh |
| 14 – 28 kWh | 60% of STC factor | ≈ $151 / kWh |
| 28 – 50 kWh | 15% of STC factor | ≈ $38 / kWh |
| 50 kWh + | No additional support | — |
- Example: a 10 kWh battery costing ~$11,100 receives ≈ $3,100 support → net cost ≈ $8,000
- Funding boosted from $2.3B to $7.2B in 2026 — but per-battery support still steps down over time
- Stacks with state programs — see your state rebate page for combinations

Who Qualifies — and How to Claim
Eligibility is refreshingly broad: homeowners, landlords, small businesses and community facilities all qualify, and there's no income means test. The requirements that matter are technical:
- The battery must be new, with a nominal capacity of 5–100 kWh (support applies to the first 50 kWh of usable capacity).
- It must be installed by an accredited installer using approved equipment.
- The home needs new or existing rooftop solar — adding a battery to panels you already own is fully eligible.
- One battery system per electricity meter.
Claiming is even simpler: your installer handles the certificates and applies the value as an upfront discount, so the quote you sign is the discounted price. The only step you need to take is confirming your home qualifies — which is exactly what our free check does, alongside every state incentive for your postcode like the NSW battery incentive or WA battery scheme.
Battery + solar at the same time?
If you don't yet have panels, installing solar and battery together lets you claim this discount plus the solar panel STC rebate in one project — the combination behind most of the "$0 net cost" outcomes our analysts find.
Federal Battery Rebate FAQs
The questions Australians ask most about the Cheaper Home Batteries Program.
How much is the federal battery rebate in 2026?
The Cheaper Home Batteries Program discounts home batteries by roughly 30% — about $252 per usable kWh in 2026. A typical 10 kWh battery attracts around $3,100 in support, bringing an $11,000 install down to roughly $8,000.
What changed on 1 May 2026?
Support was re-tiered by battery size: the first 14 kWh of usable capacity earns the full rate, capacity from 14–28 kWh earns 60% of the rate, 28–50 kWh earns 15%, and capacity above 50 kWh receives nothing. Program funding also grew from $2.3 billion to $7.2 billion.
Who is eligible for the Cheaper Home Batteries Program?
Homeowners, landlords, owner-occupiers, small businesses and community facilities — with no income means test. The battery must be new, between 5–100 kWh nominal capacity, installed by an accredited installer, and paired with new or existing rooftop solar.
Can I claim it for a battery added to my existing solar?
Yes — adding a battery to an existing solar system is fully eligible and is one of the most popular upgrades of 2026. You don't need to buy new panels to claim the battery discount.
Does the federal battery rebate stack with state incentives?
Yes. It stacks with programs like the NSW PDRS incentive, the WA Residential Battery Scheme and interest-free loans in Victoria and the ACT — plus the solar panel STC rebate if you install panels at the same time.
How do I actually claim the discount?
You don't lodge anything. Accredited installers claim the certificates and pass the value on as an upfront discount on your quote. Your job is simply to confirm eligibility — start with our free 30-second check.
Will the rebate keep shrinking?
Yes — like the solar STC scheme, support is designed to step down as the program matures, and the May 2026 changes already reduced support for larger systems. Installing sooner locks in the current rate.
Is one battery per house the limit?
The program supports one battery system per electricity meter. If you own multiple properties, each property with its own meter can claim its own discount.
