How Rebates Can Lower the Cost of Solar for Homeowners



Thinking of investing in solar energy? Not only will you be helping save the planet, but you’ll also be able to save money on your energy bills. Depending on a number of factors, using solar energy in your home may make you eligible for a rebate on your installation fee that could save you thousands of dollars.

At Think Renewable, we get tonnes of questions every day about solar panel rebates, also known as STC rebates, so we’ve put together this list of questions and answers cover everything you need to know.

What is the STC Scheme?

STC stands for Small-scale Technology Certificate. The Certificate equates to 1 megawatt hour of renewable electricity sourced from a small-scale system such as a solar panel.

As part of the Australian Government’s Small-scale Renewable Energy Scheme, individuals and small businesses can receive financial incentives when they install solar panel systems.

How Much Can You Get Back from the STC Scheme?

This will vary considerably depending on where you live, your income, the capacity of your solar system and many other factors. However, in some cases, you may be eligible for up to 50% off the cost of your installation.

How Do I Get My Rebate?

In most cases, claiming your solar rebate is straightforward and easy. However, there are a few things you need to ensure to make sure that you qualify.

  • Your panel must be approved by the Clean Energy Council (CEC)
  • The installer of your system must be CEC accredited
  • You need to claim your rebate within 12 months of installation

If you tick all of those boxes, you can apply for the rebate through the Clean Energy Regulator by clicking on “Claiming Small Energy Certificates” and follow the prompts.

You’ll need to prove your eligibility, fill out the necessary compliance forms and join the REC Registry to finalise your application.

Alternatively, like all of our happy customers, you can allow Think Renewable to claim the rebate on your behalf and have the amount as a discount off of your solar systems cost!

How is the Rebate Calculated?

There are many factors that contribute to the size of your rebate, but as a general rule, the more energy your solar panel system creates the bigger your rebate. Things like the average daylight hours in your state and the size of your solar panel will play a large part in the size of your rebate.

For example, if you have a 6kW panel in Perth (which has 8.8 hours of sunshine per day on average), the size of your rebate will be larger than if you have a 3kW panel in Victoria, which averages 6.5 hours of sunshine per day.

There are also different rebates and rates available from state to state, which we will cover below.

Who is Eligible to Claim the STC Rebate?

The STC Rebate is available to all Australian homeowners and is not subject to any restrictions such as means testing. The only reason you may not qualify is if either the company who installed your solar panel or the solar panel itself is not CEC accredited.

How do Solar Rebates Vary by State?

While every state has rebates available, some states have additional incentives in addition to the Federal Government Rebate and alternatives.
