How much is the federal battery rebate worth in Sydney?

From 1 May 2026, the federal battery rebate is worth approximately $252 per usable kilowatt hour for most standard home batteries. The table below shows what that looks like across the most common battery sizes installed in Sydney homes.

Battery System	Usable Capacity	Est. Federal Rebate	NSW PDRS Incentive	Total Savings
Entry level	10 kWh	~$2,520	Up to $1,500	~$4,020
Most popular	13.5 kWh (e.g. Tesla Powerwall 3)	~$3,402	Up to $1,500	~$4,902
Best rebate value	14 kWh	~$3,528	Up to $1,500	~$5,028
Medium system	20 kWh	~$4,234	Up to $1,500	~$5,734

Federal rebate figures are estimates based on the post-May 2026 STC rate of ~$252/kWh for the first 14 kWh. Capacity above 14 kWh is rebated at a lower tiered rate. NSW PDRS incentive requires VPP connection. Figures are indicative only and will vary based on your installer and STC spot price at time of installation.

How does the rebate work?

The Cheaper Home Batteries Program provides an upfront discount on the purchase and installation of home batteries through the Small-scale Renewable Energy Scheme (SRES), the same framework that has delivered the national solar panel rebate for years. SolarQuotes

Homeowners do not need to do anything to claim the rebate. Installers apply for it and deduct the value from the total system price. You simply receive a lower invoice on the day. SolarQuotes

The rebate is calculated using Small-scale Technology Certificates (STCs). The number of STCs your battery earns depends on its usable capacity and the current STC factor. Sydney Solar and Electrical handles all of this on your behalf. You will see the rebate clearly itemised on your quote before you commit to anything.

Australian households, businesses and community organisations can receive a discount of around 30 per cent on the upfront cost of installing a range of small-scale battery systems. To qualify, your installation needs to meet a few straightforward requirements:

Your battery must have a usable capacity of between 5 kWh and 100 kWh
The battery must be connected to an existing or new solar PV system
There is no income or means test — all Australian homeowners with eligible properties can apply
One rebate per electricity meter (NMI) — owners of multiple properties may claim separately at each
The battery must be VPP capable (joining a VPP is optional — the hardware just needs to support it)
The battery must be on the Clean Energy Council (CEC) approved product list
Installation must be carried out by an SAA-accredited installer

      Typical Household
    
      0 to 14 kWh
      100% of STC factor
      Average family home
    
      14 to 28 kWh
      60% of STC factor
      Larger homes or small business
    
      28 to 50 kWh
      Reduced STC factor
      Commercial or large property
    
      Above 50 kWh
      No rebate applies
