SA Home Battery Subsidy Scheme

What is the SA Home Battery Subsidy Scheme?

The SA Home Battery Subsidy scheme launched in 2018 and will directly reduce electricity costs for the 40,000 households that purchase a subsidised household energy storage system.

About the scheme

Subsidy & Finance

  • The subsidy is limited to 40,000 South Australian homes
  • The subsidy covers up to $6,000 of the cost of your battery for energy concession holders and $5,000 for all other households
  • Battery prices start from $9,000 so you will have out-of-pocket expenses after your subsidy is deducted. However, as part of the scheme, the Government is offering low interest finance to cover the gap, including the cost of purchasing or upgrading your system.

Your choice of battery

Suntrix is pleased to offer you a choice of quality brands – Sonnen, Alpha-ESS and Tesla Powerwall. When making your decision on the best battery for your home, there are several things you should take into consideration:

  • The size of your existing solar PV system –  is it adequate for your year-round storage needs or do you want to upgrade to a bigger system to ensure your battery is working the best it can in winter as well as summer?
  • How important is back-up functionality for you in the event of power black-outs?
  • Do you have an appropriate space for the battery to be installed?
