NSW solar and battery rebates, with sources.

A plain-English breakdown of what NSW homeowners can claim in 2026 — federal STCs, the Cheaper Home Batteries Program, and the NSW Peak Demand Reduction Scheme. Every figure on this page traces back to a .gov.au source.

NSW state programs

NSW VPP Incentive (Peak Demand Reduction Scheme)

Administered by NSW Climate and Energy Action · Status: open — Open. Replaces the standalone NSW battery installation incentive that ran Nov 2024–Jun 2025.

A top-up incentive — typically $550 to $1,500 — for connecting a new battery to an approved Virtual Power Plant (VPP).

What it is worth: Approximately $550–$1,500 per battery, depending on usable kWh. Calculated against an Accredited Certificate Provider and capped at 28 kWh of usable capacity for the incentive. Confirm the exact figure with your installer or ACP — NSW publishes the headline rebate but not the per-kWh table.

Eligibility

  • Use an Accredited Certificate Provider (ACP)
  • Connect the battery to an approved Virtual Power Plant for the duration of the scheme
  • Battery must also be eligible for the federal Cheaper Home Batteries Program

Stacks with

  • Federal Cheaper Home Batteries Program (explicitly designed to stack)
  • Federal STCs on the solar panels

The catch most people miss: The NSW top-up is VPP-conditional. If you don’t want a third-party VPP operator dispatching your battery during peak demand events, you lose the incentive entirely. Make sure your installer explains the trade-off before you sign.

Federal programs — these apply in NSW 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

Does the NSW VPP incentive stack with the federal Cheaper Home Batteries rebate?
Yes. NSW explicitly designed the VPP incentive to stack on top of the federal rebate. A 10 kWh battery in NSW can attract both, but only if it’s connected to an approved Virtual Power Plant.
Is there still a NSW solar panel rebate in 2026?
No. The standalone NSW solar PV rebate has ended. Solar panels in NSW are still subsidised through the federal STC scheme, which applies in every state.
What postcode zone is Sydney in for STC purposes?
Sydney is in Zone 3 with a zone rating of 1.382. Far northern and inland NSW postcodes can fall into Zone 2 (rating 1.536). Your installer applies the right zone based on your address.
When does the federal battery rebate get smaller?
The STC factor for batteries stepped down from 8.4 to 6.8 per usable kWh on 1 May 2026, and it steps down again each year toward the scheme’s 2030 end. The earlier you install, the larger the rebate.
How do I check I’m being quoted a real rebate amount?
Ask the installer to show you the STC calculation and the NSW ACP paperwork. Real rebates trace to cer.gov.au (federal) and energy.nsw.gov.au (state). Anything else is marketing.
