Queensland

Queensland solar and battery rebates, with sources.

Federal-only: the QLD Battery Booster has been closed since its $16M allocation was exhausted, and there’s no current statewide solar rebate for owner-occupiers. The honest picture is that QLD homeowners now claim federal STCs and the federal Cheaper Home Batteries Program — both still substantial.

QLD state programs

No active Queensland state rebate for owner-occupier solar or batteries as of May 2026. The Battery Booster program closed after its $16M allocation was exhausted (qld.gov.au).

Federal programs — these apply in QLD too

Small-scale Technology Certificates (STCs)

Administered by Clean Energy Regulator · Status: open — Open, phasing down annually until scheme end in 2030

An upfront discount on your solar panel system, applied by the installer at point of sale.

What it is worth: Calculated as: system size (kW) × your postcode zone rating × deeming period (5 years in 2026). Each STC trades on the open market — typically around $36–$39. A 6.6 kW system in Sydney (Zone 3) currently generates around 44–46 STCs.

Eligibility

  • System size ≤ 100 kW
  • CEC-accredited installer and CEC-approved panels and inverter
  • New install (not a replacement of an existing system claimed within the same window)

Stacks with

  • Federal Cheaper Home Batteries Program (battery STCs are a separate stream)
  • Every active state rebate stacks with STCs

The catch most people miss: STC value drops every 1 January as the deeming period shrinks by one year. A system installed in December 2026 is worth meaningfully more in STCs than the same system installed in January 2027.

Cheaper Home Batteries Program

Administered by Department of Climate Change, Energy, the Environment and Water (delivered as STCs) · Status: open — Open since 1 July 2025

Roughly a quarter off the installed cost of a home battery, applied upfront like the solar STC.

What it is worth: Calculated as: usable battery kWh × STC factor × certificate spot price. From 1 May 2026 the STC factor is 6.8 per usable kWh (down from 8.4 in Jan–Apr 2026). Tapered above 14 kWh — 60% rate from 14–28 kWh, 15% rate from 28–50 kWh, nothing above 50 kWh.

Eligibility

  • Battery installed on a new or existing solar PV system
  • Usable capacity between 5 kWh and 100 kWh nominal
  • One battery rebate per address — only the first battery at any site qualifies
  • System commissioned on or after 1 July 2025

Stacks with

  • Federal STCs on the solar panels
  • NSW VPP incentive
  • WA Residential Battery Scheme
  • NT Home and Business Battery Scheme
  • ACT Sustainable Household Scheme loan

The catch most people miss: The STC factor steps down on 1 May each year. An identically-priced battery installed 30 April 2026 is worth roughly $300–$400 more in rebate than the same battery installed 1 May 2026 (10 kWh example). Homeowners who delay past April lose meaningful money.

Common questions

Is the QLD Battery Booster coming back?
The Queensland Government has not announced a replacement scheme as of May 2026. Existing Battery Booster installs are in a safety and compliance audit phase. Anything offering a Battery Booster rebate today is either historical paperwork or a scam — verify on qld.gov.au.
So what can a Queensland homeowner actually claim?
Two federal programs apply: STCs on solar panels (delivered as an upfront install discount) and the Cheaper Home Batteries Program on the battery (delivered the same way). Combined, these still cover a meaningful share of a typical solar-plus-battery quote.
What zone is Brisbane in for STC purposes?
Brisbane is in Zone 3 with a zone rating of 1.382. North Queensland (Townsville, Cairns) sits in Zone 2 (1.536), which means a slightly larger STC rebate per kW installed.
Are there fraudulent QLD rebate sites?
Yes. The Queensland Government has explicitly warned about phone calls and websites pretending to offer Battery Booster rebates. Anything not hosted on qld.gov.au is not the QLD Government.
Is there any QLD rental rebate?
Yes — Solar for Rentals lets landlords apply for up to $3,500 to install solar on rental properties. It’s aimed at the property owner, not the tenant.
