South Australian Solar Rebates 2024 – Incentives, Rebates, and Tariffs

Last updated: January 2024

South Australia leads all Australian states in solar adoption, with rooftop solar capable of producing enough energy to meet almost all of the state’s electricity needs 1.

On the other hand, homeowners who have not yet switched to solar face the highest energy prices in the country 2.

If you want to join the solar movement in South Australia, you can take advantage of two national solar incentives: the Small-Scale Renewable Energy Scheme, and solar feed-in tariffs.

If you live in the City of Adelaide, you may also be eligible for additional sustainability incentives.

This article will cover each offer in detail.

Understanding the Small Scale Renewable Energy Scheme

Also known as the “federal government solar rebate”, the Small-Scale Renewable Energy Scheme is a nationwide program that incentivises individuals, families, and small businesses to install small-scale renewable energy systems like household solar.

The rebate is given as Small-scale Technology Certificates (STCs). When you buy a solar system, you’ll get a certain number of STCs based on the size and location of your system.

STCs work like a currency, representing the amount of power your solar system is expected to generate until 2030. The more renewable energy your system is projected to produce, the more STCs you’ll receive.

The total value of these certificates is the amount you’ll get back as a rebate for your solar panels. This value can be subtracted from your installation cost.

How Much Will the Scheme Save Me in SA?

The federal solar rebate in SA can reduce the cost of your solar panels by around 30%, depending on your system size, your location within South Australia, and how soon you install your system. The table below shows that an average-sized solar system of 6.6kW can expect a solar rebate of approximately $2,520.

SA STC Solar Rebate Value
Gross system cost: $9,160
Solar panel rebate: ($2,520)
Net system cost: $6,640

How Do I Make a Claim?

If you install new solar panels, or upgrade/replace an old system, you’ll be eligible for the rebate if you follow the steps below:

  • Use Clean Energy Council (CEC) approved parts and choose a CEC-accredited installer.
  • Install your new solar panels within one year of creating the STCs.
  • Keep your system under 100kW, with a maximum annual production of 250MWh.

Your solar installer will calculate your STC rebate amount for you and deduct it from your installation cost, so you don’t need to do anything to make your claim.

Solar Feed-in Tariffs in SA

A solar feed-in tariff is another incentive that can boost your solar savings.

But what is a feed-in tariff?

If your solar system produces excess energy, it can be exported to the grid. For every kWh exported, you can receive a payment called a feed-in tariff.

Typically, the rates range from 5c to 10c.

The Best Solar Feed-in Rates in SA

In South Australia, feed-in tariff rates are set by electricity retailers. Unlike in other states across Australia, the SA state government does not set a minimum rate, meaning retailers can offer competitive rates.

The table below shows the best feed-in tariff rates for popular retailers across South Australia (updated January 2024), with the minimum and maximum rates on offer.

The best solar feed-in rates in SA
Retailer: Min FiT: Max FiT: Conditions:
Origin Energy 6.0c 20.0c* *For customers that purchase a solar system with Origin only.
Energy Australia 8.5c 8.5c
AGL 6.0c 6.0c
Simply Energy 5.5c 5.5c
Momentum Energy 3.5c 3.5c

How Do I Access Feed-in Tariffs?

To be eligible to receive feed-in tariffs across South Australia, you’ll need to have a grid-connect solar system installed at your home. If you have multiple solar energy systems installed, only one per household is eligible to receive the tariff.

Not all electricity providers offer feed-in tariffs, and some have specific conditions, like limiting eligibility to customers who purchase their solar panels through them.

You’ll receive your feed-in tariffs paid as a credit on your electricity bills.

Are Feed-in Tariffs Worth It?

While feed-in tariffs can help you pay back your system, choosing a system size that can cover your electrical requirements without producing excess energy will deliver greater savings.

This way, you’ll only pay to install what you need, and you can self-consume your solar energy to power your appliances directly rather than exporting excess energy to the grid.
