We breakdown all State & Federal incentives and solar rebates so you can get the best deal.

The Federal Government’s STC Rebate (Small Scale Technology Certificates) provides a big upfront discount on your solar system.

Find everything that you need to know about the federal STC rebate below and get the best price for your system.

What is the Federal Government's solar rebate?

Firstly, “Small-Scale Technology Certificates” (know as STCs) are technically an incentive scheme, not a solar rebate. Semantics aside, STCs deliver you an upfront discount when you install a solar power system at your home. These certificates are traded (usually by your installer) in exchange for a dollar amount which is then deducted from the cost of your installation.

The number of STCs that you’re entitled to decreases on the 1st January each year. In short, the longer you wait to install solar, the smaller your discount from the STCs will be.

Only Clean Energy Council (CEC) accredited installers are able to offer STCs discounts. This is great news for you if you get 3 quotes with Solar Market, because all of the suppliers we connect you with will be CEC accredited!

How do STCs work?

In 2011, the Australian Federal Government introduced the Small-Scale Renewable Energy Scheme (or SRES) to encourage homeowners and businesses to install solar systems. STCs were introduced as the mechanism to deliver the financial incentive to people who install solar systems less than 100kW in size (For systems 100kW and bigger, Large-scale Generation Certificates, know as LGCs, apply).

An STC discount is generally applied on your quote from your installer. You will usually see a total cost, the STC discount applied, and the final out-of-pocket expense after the discount. This discounted amount is generally what you have to actually pay the installer. Sometimes, you might not see the STC amount on your bill because it’s automatically applied, but you can always double check with your installer.

When your system is installed, your install will probably ask you to assign your STCs over to them so they can then trade them in exchange for the dollar amount.

Let’s take a look at how the STCs themselves are determined below…

The number of STCs your solar system is eligible for is based on the expected amount of green electricity your new solar system will generate.

Calculate your STC discount

Start By Calculate Your Number of STCs

The reason it’s important to know about the size of your system, your zone and the deeming period is because each of these factors are part of the STC rebate calculation.

The calculation itself is as follows:

For Example

Let’s apply this STC rebate formula to a real life example.

Greg is planning on installing a 6.6kW solar system on his home in Cairnes, QLD (zone rating 1.382) in 2023 (deeming period 8) and wants to know how many STCs will be available to him.

Greg simply has to multiply these values all together, round down, and he’ll have the number of STCs available to him, in this case 72.

Calculate Your STC Rebate Discount

Once you have your number of STCs, you can multiply that by the dollar value STCs are being traded at that moment in time to get your estimated discount amount. You can check the current market value of STCs on various trading platforms like Demand Manager.

This dollar amount will be the estimated STC rebate you’ll get on installation day. Go you!

If you’re wanting a rough example STC value to get you going, $38 an STC is about right these days.

Going back to our example, Greg can expect a dollar discount of $2,736 on his 6.6kW system if he gets $38 an STC!

Remember, the number of STCs awarded decreases each year till 2030. The longer you wait the fewer STCs you’ll receive and the lower your discount at installation. Use the example below as a reference to get a better idea of the trend and how it will affect the final price of your system.

We've got the most important information you need to know about solar rebates available in your state.

In addition to the Federal Government STC incentive, some states offer extra solar rebates. Click below to learn if there is a solar panel rebate or solar battery rebate on offer from your State Government.

Northern Territory

If you’re a homeowner, business or not-for-profit organisation in the Northern Territory, we’ve got great news for you!

In addition to the Australian Federal Government’s STC incentive, in the NT you also receive the Home & Business Battery Scheme.

HOME AND BUSINESS BATTERY SCHEME

You can apply for a $6,000 grant through the state Government’s Home and Business Battery Scheme. If you’re a homeowner that also owns a business, you can do 2 separate applications and access the grant for both your home and business.

You’ll be eligible for the grant regardless of your electricity provider. However, if you currently get a premium feed-in tariff rate through Jacana Energy, you’ll be transferred to a standard feed-in tariff rate when you access the scheme.

So, let’s look at eligibility. You can apply for the grant if you are:

A registered owner of a residential property in the Northern Territory;
A registered Northern Territory business or;
A not-for-profit or community organisation operating in the Northern Territory in either owned or rented premises

The property you intend to use the grant on can be owner-occupied or be an investment property, but you’ll only be able to do one application per property and per homeowner.

You can use the funding to buy a solar power system along with an eligible battery and inverter. You can also use it to buy and install an eligible battery and inverter on their own provided you’ve already got a solar power system installed at the property Eligible batteries must have a 7-or-more kilowatt hour capacity.

Unfortunately, you won’t be able to use this scheme to fund and install solar panels and inverters where they are not being installed along with a battery.
