Solar Panel Rebate - New 2024 Guide

The Australian Federal Government’s solar panel initiative, which isn’t exactly a discount in the traditional sense as we’ll detail shortly, provides an instant cut in the cost for certified solar setups that are eligible. Known as the Small Scale Renewable Energy Scheme (SRES), this government initiative reduces the initial expense involved in installing solar panels by $431 for each kWh. This price reduction is related to the market price of STCs, which stand at $39 at present.

Under the scheme, solar systems are entitled to Small-scale technology certificates STC’s. The number of certificates that can be created per system is based on its geographical location, installation date, and the amount of electricity the system generates.

One STC is equal to 1 megawatt hour of renewable electricity either generated or displaced by the end of the deeming period. Another way to say it is, how much power your solar panel system will generate between now and the end of 2030, which is when the scheme ends. It’s sounds complex, well it is a little, but lets have a look at how you would calculate your rebate amount.

How is the STC rebate calculated?

The STC rebate is calculated with the following formula:

Solar system size (kW) x Zone Rating x Deeming Period (years) = Number of STCs (rounded down) X STC price.

Example: 6.6kW x 1.382 (postcode 2162 in zone 3) x 8 years = 72 x $39.50 = $2,844

Why 8 years? Because the STC rebate Scheme finishes at the end of 2030, so it has 8 years left. Every year the number of STC’s small technology certificates reduces. The rebate amount is paid on the number of kWh produced by your system until 2030.

Solar panel rebate by state

Firstly it depends on the state you’re living in and secondly how large scale 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

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.

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 the rebate on a 6kW solar system will be $2,633.


6kWh solar system cost: $ 9,342
Rebate = $39.90 x 66 (STC’s): $2,633
You pay: $6,709

The cost of acquiring the STCs keeps on changing relative to the demand and supply of the renewable energy certificate market. Additionally, the STCs differ in each state and depending on the level of solar PV panels. 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, the solar rebate will end, But don’t stress it’s not for another 13 years. The 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 PLENTY of time left and lots of free government money for solar panels to make it more than worthwhile to get solar installed today.

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 6kWh solar system might cost $8,841 fully installed, but the installer will only advertise the system to cost $5,992.

Basically, the advertised price of a solar system includes the rebate discount. There is no need for you to actually apply for the rebate yourself.

Solar rebates are not to be confused with solar Feed-in 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.

How Do I Know If Am Eligible For A Rebate?

Generally, across all the states, the eligibility for the solar energy rebate from the federal government is a given and all pretty similar. The following are the general eligibility requirements:

  1. The solar panels should be eligible for small-scale PV. It should be normal.
  2. The place of installing a solar power system should be eligible. It means the system should be installed in residential premises such as an apartment, townhouses, a shop or a house.
  3. The installed system must be a complete and new unit.
  4. Regardless of the deeming period, the solar credits are created once for one system installation.
  5. When applying for the STCs, the solar setup should not exceed 1 year from the date of installation.

The eligibility for a rebate in different states:


  1. A combined household income of less than $180,000 per year. Proof of income for the current or previous year should be produced or tax assessment for homeowners.

New South Wales

The 3,400 low-income households in NSW who qualify for a rebate can either opt for the rebate scheme or abandon the rebate and get a free 2.5Kw solar system. This scheme will enable the residents and small business owners to save up to $600 annually on electricity bills. To be eligible for a rebate in NSW, you should meet the following requirements:

  1. You should be already receiving the low-income household rebate
  2. Do not have an already installed solar PV system.
  3. You own your house and a roof.
  4. You should be residing in any of these places: South Coast, Central Coast, North Coast, Sydney South, and Illawarra-Shoalhaven.

You are eligible for the program if you are living or renting in a retirement village, a residential community or a strata building.


The government of Queensland is giving out interest-free loans and grants for solar and batteries. However, this does not affect the eligibility of the rebate for solar power from the federal government.

Western Australia

The Western Australian government has a very limited solar energy rebate for the solar PV system. However, you can apply for the rebates offered by the federal government. Check the federal government’s eligibility for solar rebates.

Northern Territory

  1. To be eligible for the solar rebate in NT, the system should be installed by a professional who is approved by the Clean Energy Council.
  2. The system should have the approval and meet the standards of the Clean Energy Council.
  3. Remember to attach all the necessary documentation.


The government of Tasmania did not have a domestic solar rebate in 2019. The Tasmania government offers interest-free loans to individuals and businesses under the Tasmanian Energy Efficiency Loans Scheme (TEELS). However, this does not affect the solar rebates from the federal government.

How do I get my solar rebate?

To claim your solar rebate, you need to follow this procedure:

  1. Download the STC form from any certificate and rebate companies in your respective state. Read the form and duly fill it in giving accurate information.
  2. Attach all the documents requested in the form. Attach a clear photo of the tank serial number. Additionally, issue out a copy of the site map showing the location of the tank.
  3. After duly filling in the form, send it back to the certificates trading company you obtained it from.
  4. The certificate trading company will process your payments.

The STCs should be created not later than 12 months after the solar PV system installation.

What is the Difference between Rebate, Grants and Tax Credit?

Solar Rebate – In most cases, the rebate is used by sellers to promote more sales and reduce the cost to the customer. They are a reimbursement or refund of the money spent on a particular commodity. In this case, to install solar power system. The STC scheme will enable the residents to save a lot of money on the solar power system installation.

Solar Grants – Grants are non-repayable money issued to the party by the government towards a certain project. It is given absolutely free of charge. The governments of Tasmania and Queensland are offering grants to the eligible residents.

Solar Tax Credits – this is the amount of money that a taxpayer can deduct from the taxes owed to the government. For instance, if you install the solar power system, 30% of all the costs incurred, can be claimed as part of the federal tax return. This scheme will expire in 2022. This is a way of the government rewards you for installing a solar power system.
