Government Rebates for Solar Power

The solar power rebate system is an Australian government initiative called the Small-scale Renewable Energy Scheme.

If you install an eligible solar power system, you will receive a rebate by claiming the Small-scale Technology Certificates (STCs).

The STCs are tradable certificates that you or a registered agent can create and trade for a discount in the cost of the solar system. This scheme enables you to save a lot of money in the installation of solar power. The STC scheme took effect in 2017 and will end in the year 2030.

How much is the solar rebate?

Firstly it depends on the state you’re living in and secondly how big your solar system is. Because different regions experience different sunlight conditions, the value of Small Scale Technology Certificates (STC’s) will vary depending on the size of the solar energy system and the location.

Here is a quick look at the rebate on a 6kw system by state

State System size Zone Zone rating Rebate
New South Wales 6KW 3 1.382 $3,535
Queensland 6KW 1 1.622 $3,535
Victoria 6KW 4 1.185 $3,010
South Australia 6KW 3 1.382 $3,535
Western Australia 6KW 3 1.382 $3,535
ACT 6KW 3 1.382 $3,535
Northern Territory 6KW 1-2 1.536 $3,535
Tasmania 6KW 4 1.185 $3,010

What are Small-Scale Technology Certificates (STC’s)?

The small-scale technology certificate program is the way homeowners and installers can trade as a commodity in exchange for money after installing a residential solar system.

The current price for a single certificate is currently $36.20 (*May 2019) and your state will give you a certain number of certificates redeemable for cash depending on how many kilowatts of power you install.

These credits are also available for solar hot water systems.

And this is a list of postcode and what zone they belong to.

Who applies for the rebate me or the installer?

In reality you really won’t have to apply for or even think about the solar rebate as your installer will look after everything for you.

In fact they have already priced your solar system installed including the rebate. So if you want a 6kW solar you can get $3,535 rebate (or discount off the price of installing your solar system).


6kWh solar system cost: $ 8,000
Rebate = 6 (kw) x $590: $3540
You pay: $4,460

The cost of acquiring the STCs keeps on changing relative to demand and supply of the renewable energy certificate market. Additionally, the STCs differ in each state and depending with the level of the solar energy. Your installer will be up to date on this and again, will price your system accordingly.

Is the solar rebate ending anytime soon?

In short yes! But don’t stress it’s not for another 13 years. They solar rebate program is getting phased out slowly over 15 years starting 1st January 2017. So the rebate will reduce by 1/15th each year until it ends in 2032.

So there is still PLENTLY of time left and lots of free government money to make it more than worthwhile to get solar installed today.

How much rebate do I get for solar power?

Under the STC program, a megawatt hour in energy production is eligible for a renewable energy certificate (REC). The STCs are only issued for the solar panels and the solar power systems that are meet the recommended standards.

The amount of rebate you get for the solar power depends on three factors such as the state or location, the fluctuation value of the STCs and the deeming period, it goes up every year.

You can use a STC calculator to know how much STC you qualify for. Here is how to calculate the number of STCs you are eligible for: The size of the solar system x the postal code rating x the Deeming Period. If the deeming period is short, you will get lesser STCs. For Example, in 2018, the deeming period was 13 years, in 2019 it is 12 years.

How do I apply for a government Solar Rebate?

There is no need to apply for a solar rebate. This is something that the installer does on your behalf and is priced into the system cost.

So a typical 5kWh solar system might cost $7000 fully installed, but the installer will only advertise the system to cost $3500.

Basically what he is doing is collecting your half off you, then collecting the other half from the government.

There is no need for you to actually apply for the rebate yourself.

Solar rebates are not to be confused with solar Feedin Tariffs. Once you have your solar system hooked up to the grid, you will need to speak to your energy company about how much money they will pay you to feed your excess power back into the grid.
