Residential Battery Scheme

Paving the way for a renewable-powered future – Solar Battery

The day is not away from South Australia when solar home batteries will pay for themselves. South Australia’s (SA) Home battery scheme is launched to help 40,000 South Australians to pay for the installation of the home solar battery systems. The home battery subsidy is calculated on the usable kilowatt-hour capacity of the battery purchased. Moreover, higher concession subsidy is available for low-income SA households supporting to access the solar battery scheme.

There are two levels of Home battery subsidy:

Energy concession holder (pensioners and people receiving Centrelink payments): $600.00 per kilowatt-hour (kWh)

All other households: $500.00 per kilowatt-hour (kWh)

For instance, a solar battery system with 5kWh of storage is able to receive a maximum $2500 subsidy or $3000 for concession holders. The subsidy varies according to the usable battery storage; however, a maximum of $6,000 is capped per home battery installation.

 

What is a home battery system?

A typical home battery system comprises panels, an inverter and a battery. The solar photovoltaic system converts energy received from the sun into electricity. This electricity can be used in households and excess can be fed into the main electricity grid.

Another solar solution is to store the excess electricity generated in the daytime by connecting a battery to the solar energy system. The stored energy can be used at night time or during days when the system is not generating much. This smart home solar battery system can further help in saving money on your energy bills. It can be concluded that installation of the solar battery storage will reduce the burden on the grid or network, and facilitate lowering of electricity prices in South Australia.

solar power systems with battery storage

There are a few reasons you may want to add batteries to your solar panel system:

  • Use your generated solar energy at night time.
  • Reduce power consumption during peak periods.
  • Batteries can provide backup where there is a power outage.
  • Become more self-sufficient by reducing the effects of increasing electricity prices
  • Save money by charging your battery from your power grid at off-peak times.

Types Of Battery Storage System

Battery Storage

DC coupled battery storage system

It can only be connected with outputs generated by solar panels, therefore, only storing energy produced by solar panels.

AC coupled battery storage system

In this energy storage system, the yielded solar energy from the panels is stored in the batteries by employing a common solar inverter coupled to a battery inverter or charger. Once connected to the AC side of the solar inverter, it allows the battery to store energy from both solar panels as well as the power grid.

What batteries are eligible for SA Home Battery subsidy?

Battery Storage

There are a couple of storage battery bands that are currently approved for the SA Battery Scheme subsidy. It is a requirement that the battery system must be of virtual power plant capability (VPP). This allows energy retailers to power the grid by discharging the battery.


There are certain technical criteria that must be met by solar battery storage systems:


  • Solar battery system designer and installer must be CEC-accredited.
  • The battery system must possess a minimum of a 5-year warranty including workmanship and a 7-years warranty of battery components.
  • The system must be of VPP capability
  • Priorities will be given to providers who obligate on to manufacture or assemble the system in South Australia.

Here are some storage battery brands that are compatible with most of the existing systems:

BYDEguana TechnologiesRedback
LG ChemTeslaSolax
Alpha –ESSEnphasePylontech
SonnenVarta 

Eligibility for SA government battery subsidy

Battery Storage

The SA Battery Scheme subsidies are available to everyone in South Australia who is connected to the grid, however, it is only available to the owner of the property.

  • One subsidy per property
  • Residential property connected to SAPN distributor network
  • Only approved and eligible equipment can be installed by an accredited system provider.
  • Must be the owner of the property or must have consent from the owner to install the subsidized battery system.
