How The SA Home Battery Solar Subsidy Works

The SA home solar battery subsidy is an amount given by the state to residents to to reduce the cost of a solar battery.

The subsidy pays per 1kWh of battery storage. So if you have a Tesla Powerwall 2 14kWh battery, your subsidy will be calculated as follows:

14(kWh) x $150 = $2,200

Maximum subsidy of $2,000 would be awarded for this battery. Let’s look at some others.

Solar Powerwall 214kWh$12,750$2,000$10,750
Fronius Symo Hybrid5kWh$5,550$750$4,750
Alpha-ess Smile 513.6kWh$9,084$2,000$7,084
LG RESU 3.33kWh$2,511$4,50$2,061

Unlike a rebate where customers can get a refund, the subsidy amount goes to the business or industry.

You can expect a $150 subsidy per 1kWh of battery system. If you are an energy concession holder you can get $200 per kWh. If you buy a Tesla Powerwall and opt for the Virtual Power Plant VPP program, you can get $2,000 total.

Do I need to have solar installed?

Too get the the solar battery subsidy, you will need to have a solar sstem installed unless you are applying fr the VPP program in which case you will not need a solar system.

Does Adding A Battery To My Solar System Affect My Feed-Tariff

In short yes, but it means you will be saving more. Normally a solar system will reduce your power bills by 85-90%. Thats because you use the grrid as a virtual battery and you feed power in at off-peak times and draw during peak times. This is why you can not eliminate your power bill completely.

With a battery you will come pretty close to a $0 power bill each month, so don’t worry too much about the feed-in tariff.

Who Is Eligible For An Energy Concession In SA

In SA, residents who can’t pay their electricity bills without help can apply for energy concessions. Those on a low or fixed income are eligible for energy concessions.

If you are in this situation, it is encouraged that you contact your electricity retailer for a discussion on how to pay reduced electricity bills.

Make sure to confirm how long it takes before your concession application is reviewed and accepted.

STC Solar Rebate In SA

Besides the home battery subsidy, you can also get a reduction in the cost of purchase and installation of solar panels through an STC solar rebate.

This solar rebate reduces the cost of your solar system by about $5,992. This is for a 6kWh solar system. The amount of rebate you receive is determined by several factors.

  • The size of the solar system
  • The deeming period (normally 9 years)
  • The zone of your location
  • Current STC value

The size of the system – The rebate is calculated based on the size of the system you will be installing. The bigger the system, the bigger the rebate.

The deeming period – This period is taken into consideration and factored in while calculating your rebate. The longer the period the higher the rebate.

The zone of your location – The Clean Energy Council zones Australia into 4 zones based on the intensity of sunshine they get. Each zone has a rating used in the calculation of the rebate amount.

Current STC price – Finally, the value of the STCs also determines how much you will receive as the rebate amount. STCs are traded in the market. Their value depends on the cost at the time you purchase your solar panels.


The solar subsidy is available to every Australian who wants to purchase and install solar panels on their property. You can also access additional financial aid from the department of energy and other partners at the state level to purchase and install solar and battery.

You don’t need to go through any formal application process to claim the rebate in SA because it is offered as a point-of-sale discount. To access the battery subsidy under the home battery scheme, you need to approach an approved battery installer like Tesla. They will help you with the claim and also offer advice on the best battery pack for your PV system.

Your PV install must be eligible under the feed in tariff scheme as provided by the electricity company to qualify for the feed in tariff. Those who installed their PV system before 2013 qualify for higher feed in tariff rates from the distributor network. You can also get access to a better feed in tariff if your electricity retailer has an attractive rate and is willing to install the necessary equipment on your electricity setup.

You can access the feed in tariffs if you are renting provided you purchase your system from an accredited solar vendor. You can also access the battery financial aid as well as the feed in tariff by feeding your surplus energy to the grid. Energy companies that accept fed-in power will compensate you for the amount of electricity you sell to them.
