Residential Solar Incentives

Incentives and feed-in tariffs

Residential solar incentives and rebates are still applicable. Small-Scale Technology Certificates (STCs) are available to residential solar customers, helping to reduce the cost of your solar system. However, the STCs are due to end in 2030.

In addition to the above, the Australian Federal Government and the Western Australian State Government announced in 2025 that they would make rebates available on solar battery systems.

The Federal Government rebate is set at $372 per kW of battery capacity. For example, a 10 kW battery could receive up to $3,720 in rebates.

While the State Government rebate is expected to be around $1,300 for a 10kW system, the eligibility criteria for this rebate are to be confirmed soon.

These incentives drastically reduce your upfront costs, allowing you to start generating and storing your clean energy without relying on the grid, and cut your electricity bills in the process.
 

Discounts on solar systems with residential solar incentives 

Currently, your Solar Energy System is paid for using a combination of your own money and money generated from STCs that come with your solar system. An STC is the equivalent of one megawatt hour of electricity generation from an accredited renewable energy source (your solar system). An STC is similar to a share certificate as it represents a unit of value and may be traded for financial return. STCs are traded on the stock market like any commodity, and their unit value varies from day to day.

Government incentives allow 6 years' worth of STCs to be credited and used upfront to pay for your solar system partially. In effect, you cash in the equivalent of 6 years of renewable energy output for a discount on your solar system. This incentive is decreasing annually and is scheduled to end by 2030. Therefore, it is essential to purchase your system as soon as possible to maximise the benefit of this incentive.

You assign your STCs to Termico Solar Generation in exchange for a discount on your solar system. This discount can be as much as 45% off the cost.  Find out your pay back period and call us to find out how much you can save. 

Solar rebate via feed-in tariffs

You receive a rebate with a feed-in tariff, which pays you for the electricity generated by your solar system. Energy generated and not used (during the day while at work or during low consumption times) is fed back into the national grid, earning you energy credits. The credits earned under the feed-in tariff are either credited to your electricity account or paid to you in the form of a cheque. This occurs quarterly or annually, depending on your electricity retailer.

Western Australian solar households in Perth and the south-west region of the state are served by Synergy as their electricity provider and receive a solar feed-in tariff under the Distributed Energy Buyback Scheme (DEBS).

Currently, in the 2024-25 financial year, a kilowatt-hour (kWh) of surplus solar electricity exported to the grid will receive the following feed-in tariff:

From 3pm in the afternoon to 9pm in the evening: 10c
From 9pm in the evening until 3pm in the afternoon: 2c

Therefore, it is best to use as much of the solar energy you generate during the day as possible, rather than feeding it back into the grid.
