Queensland - Updated September 2026
Queensland solar battery cost calculator & rebates
Every Australian state and territory can access the federal Cheaper Home Batteries Program in 2026 (about $252/kWh on the first 14 kWh of usable capacity, tapering above that). Figures verified as of July 2026.
Queensland's Battery Booster rebate has closed. Sunshine State homeowners still receive the federal battery discount when they install through an accredited installer.
High solar uptake in QLD makes batteries attractive for storing daytime solar for evening use.
Cost in Queensland: Queensland solar battery cost after rebates usually means federal STCs only. Strong solar output can improve payback, but low feed-in tariffs make self-consumption (and accurate cost vs savings modelling) the key decision.
- Federal CHBP rebate applies in Queensland
- Battery Booster state rebate closed
- Strong solar export - battery savings depend on import vs feed-in tariff gap
- Coastal and regional installs may vary in price

Solar battery cost in Brisbane
Brisbane and south-east Queensland have some of the highest rooftop solar penetration in the country. With the state Battery Booster rebate closed, upfront discounts come from the federal Cheaper Home Batteries Program only. Gross installed prices for a 10 kWh system typically range from about $9,000 to $14,000 before rebates.
After the federal discount (roughly $2,500 on 10 kWh in mid-2026), many Brisbane metro households see net cost around $6,500-$11,500 for a 10 kWh battery. South-east Queensland's strong daytime solar output can fill a battery quickly, but low feed-in tariffs mean the real value is storing your own solar for evening use rather than exporting at a few cents per kWh.
Coastal and regional QLD installs outside Brisbane may vary in travel and hardware access costs, but rebate rules are the same statewide. Run the calculator with QLD selected and enter your feed-in tariff - it often moves payback more than a small city premium on install labour.
- Typical 8 kWh net after federal rebate: about $6,500-$9,500
- Typical 10 kWh net after federal rebate: about $6,500-$11,500
- Typical 13.5 kWh net after federal rebate: about $9,000-$14,000
- High solar export makes battery sizing and tariff inputs critical
- Battery Booster state rebate closed - federal only for upfront discount

Bill drop: $1,489/yr ($1,604 - $115)
Payback uses $1,241/yr modelled savings, not the full bill drop. Storing solar means you forgo about $248/yr of feed-in tariff on that energy.
Installing in 2027 instead would reduce your federal rebate by about $619.
Simple payback period
8.2 years
Optimal payback is based on this calculator's inputs and assumptions only (usage, solar size, tariffs, rebate rules, and indicative installed costs). Real-world payback varies with installer quotes, site conditions, and how you use power. This is an estimate, not a guarantee.
These are estimates. The next step is real installer pricing for your home.

Compare quotes fairly
Take this to installers so you compare like-for-like, not just the headline price.
- 1Usable kWh (not nameplate)Compare like-for-like usable capacity. Marketing peak or nameplate figures can differ from what you actually get to cycle each day.
- 2Gross price vs rebates, itemisedAsk for the installed price before rebates, then the federal STC discount and any state rebate shown as separate lines - not a single 'after rebate' number.
- 3Backup scopeConfirm whether backup covers the whole home or essential circuits only, and whether the backup gateway / switchboard work is included in the price.
- 4Commissioning date / STC yearThe federal discount steps down from 1 January 2027. Check which STC year the quote assumes, since a later commissioning date can reduce the rebate.
- 5State incentive eligibilityCheck any state scheme you may qualify for (for example the WA Residential Battery Scheme, or NSW VPP incentives and interest-free loans) and whether the quote accounts for it.

How we calculated this
- Estimated daily usage: 24.4 kWh (implied household load from a $400 quarterly bill after existing solar at $0.30/kWh).
- Battery selected: GoodWe ESA (~16 kWh) (16 kWh usable). Indicative installed cost before rebates.
- Installed cost uses an indicative midpoint for the selected system (before rebates).
- Federal rebate uses STC factor 6.8 (install in 2026). From 1 Jan 2027 the factor drops to 5.7.
- Flat-rate plan: import at $0.30/kWh, feed-in at $0.05/kWh.
- Battery savings use the gap between import and feed-in (~$0.25/kWh) on solar stored instead of exported.
- Savings assume about 85% of battery capacity can be cycled when excess solar is available.
- Before battery: ~14.7 kWh/day grid imports (solar offsets ~9.8 kWh/day of daytime use).
- After battery: ~1.1 kWh/day grid imports (13.6 kWh/day stored solar used overnight).
- Annual bill before/after is the energy portion at your import rate (supply charges not included).
- Bill drop (before minus after grid energy cost): ~$1489/yr.
- Modelled battery savings used for payback: ~$1241/yr (shifted solar at import minus feed-in, never more than the bill drop).
- Queensland Battery Booster rebate is closed; federal rebate applies.
- Existing 6.6 kW solar: ~27.7 kWh/day generation, ~18 kWh/day excess after ~9.8 kWh daytime use.

Queensland battery rebate FAQs
Does Queensland have a battery rebate in 2026?
The state Battery Booster program is closed. The federal Cheaper Home Batteries Program still provides a point-of-sale discount nationwide.
How does feed-in tariff affect battery savings in QLD?
If you export a lot of solar at a low feed-in rate, storing excess solar for evening use can improve savings. Enter your feed-in tariff in the calculator for a realistic estimate.
Can I stack Queensland and federal rebates?
With the state program closed, only the federal rebate applies for upfront discounts on new installs.
How much does a solar battery cost in Brisbane?
Most Brisbane metro 10 kWh installs net around $6,500-$11,500 after the federal rebate in 2026. Enter your bill and feed-in tariff in the calculator above with QLD selected for a personalised estimate.
