Rebates and assistance


Solar battery storage discount


The ACT Government Household Battery Storage program provides Australian Capital Territory households and businesses with a discount to install a battery storage unit connected to a new or existing rooftop solar PV system.

Through this program, the ACT Government is subsidising battery storage in around 5000 Canberra homes and businesses. 4 battery storage and solar PV companies have been selected to do the installations through a competitive process.

The current rebate is $825 per kilowatt (kW) up to a maximum of 30kW. A typical household system of 5kW would be eligible for about $4000 in financial support.

If you're adding the battery system to your existing rooftop solar, a typical residential system will cost between $8,000 and $10,000 after the rebate has been applied.*

If you don't already have rooftop solar, a typical residential system combined with solar panels will cost between $13,000 and $18,000 once the rebate has been applied.*

*Disclaimer: System costs and payback periods vary significantly depending on a range of factors including but not limited to energy usage and electricity prices, technology type, brand and system size. You should discuss this with your provider.


  • The battery is charged with free solar energy from a solar PV system which can be used when needed, even when the sun isn’t shining.
  • Energy bills can be reduced by using battery power at peak times when electricity from the grid is more expensive.
  • The battery may also:
    • provide backup power during a grid outage (some systems)
    • reduce peak demand on the energy network
    • reduce greenhouse gas emissions.


To be eligible for the discount you must:

  • have a new system that has not already been supported by the program
  • be connected to the electricity grid
  • be coupled with solar PV panels
  • Include a new or existing inverter that meets technical requirements
  • own or rent a property located in the ACT
  • have a suitable location for the battery.
