Switching to solar energy is one of the smartest moves Australians can make to cut electricity bills and reduce carbon footprints. But here’s the reality—many homeowners and businesses are unaware of the generous rooftop solar incentives available to lower installation costs.
If you are considering investing in a solar system, understanding these rooftop solar incentives can help you save thousands of dollars. In this detailed guide, we will break down everything you need to know, including government rebates, feed-in tariffs, battery incentives, and tax benefits.
By the end of this article, you will be well-equipped to make informed decisions and maximise your savings with rooftop solar incentives.
One of the most valuable rooftop solar incentives in Australia is the Small-Scale Renewable Energy Scheme (SRES). This scheme provides Small-Scale Technology Certificates (STCs) that reduce the upfront cost of a solar system.
The SRES incentive works as a discount, applied to the purchase of your solar system. The amount you receive depends on:
| System Size (kW) | Estimated STC Rebate | Final Cost After Rebate |
| 3 kW | $1,200 – $1,600 | $3,500 – $4,500 |
| 5 kW | $2,000 – $3,000 | $4,500 – $6,500 |
| 6.6 kW | $3,000 – $4,500 | $5,500 – $8,000 |
| 10 kW | $5,000 – $6,500 | $8,000 – $12,000 |
To qualify for the SRES rebate, you must:
Feed-in tariffs (FiTs) allow homeowners and businesses to sell surplus solar energy back to the grid. This incentive reduces electricity bills by crediting you for every kilowatt-hour (kWh) of unused solar power sent to the grid.
FiT rates vary depending on your energy provider and state regulations.
| State/Territory | Feed-In Tariff (cents per kWh) |
| New South Wales | 6 – 10 |
| Victoria | 5.2 – 10.2 |
| Queensland | 5 – 12 |
| South Australia | 6 – 16 |
| Western Australia | 2.5 – 10 |
| Tasmania | 8.5 – 12 |
Beyond national rebates, some states offer additional rooftop solar incentives to encourage solar adoption.
| State | Incentive | Eligibility |
| Victoria | $1,400 solar rebate + $1,400 interest-free loan | Homeowners earning under $210,000 |
| NSW | Interest-free loans for solar and battery systems | Homeowners and small businesses |
| South Australia | Up to $2,000 battery rebate | Households installing battery storage |
| Queensland | Energy-efficient home loans | Homeowners installing solar |
Adding a solar battery allows you to store unused solar energy for nighttime use, reducing reliance on the grid. However, batteries are expensive, with prices ranging from $7,000 to $15,000. Fortunately, there are solar battery rebates available.
| State | Incentive |
| Victoria | Interest-free battery loans up to $8,800 |
| South Australia | Battery rebate of up to $2,000 |
| New South Wales | Interest-free battery loans |
Businesses installing rooftop solar systems can benefit from instant asset write-off, allowing them to claim the full cost of solar as a tax deduction.
Rooftop solar is a powerful way to cut electricity costs, and with rooftop solar incentives, the savings are even greater. Whether you are a homeowner or a business, taking advantage of government rebates, feed-in tariffs, battery incentives, and tax benefits can significantly lower installation costs.

The amount you save depends on your solar system size, location, and the incentives available to you. The Small-Scale Renewable Energy Scheme (SRES) can reduce installation costs by $2,000 to $4,500, depending on the system size.
Additionally, feed-in tariffs (FiTs) can provide ongoing savings by crediting you for surplus electricity sent to the grid. Homeowners in states offering additional rebates or interest-free loans can save even more. Over time, these incentives significantly reduce electricity bills, delivering thousands of dollars in lifetime savings.
Yes, but they depend on the state and specific programs. Some states, like Victoria, offer Solar for Rentals programs that provide rebates to landlords installing solar systems for their tenants.
However, most solar incentives, including the SRES rebate, are available to property owners rather than renters. If you are renting, you may be able to negotiate with your landlord to install solar, especially if they can take advantage of these rebates.
Most rooftop solar incentives are applied automatically by your solar provider, so you don’t need to apply manually for the SRES rebate. When purchasing a solar system, the rebate is usually deducted upfront from the total installation cost.
For state-based rebates and loans, you may need to apply directly through your state’s energy department. For example, in Victoria, you must submit an application for the Solar Homes Program before installation. Always check your state’s official energy website for current eligibility and application processes.
Yes, but they are limited. While the SRES rebate applies only to new installations, you may still qualify for state-based battery rebates or feed-in tariff upgrades when adding a solar battery or increasing your system size.
Some energy retailers also offer better feed-in tariff rates for larger or more efficient systems. If you already have a solar system, upgrading your inverter, adding more panels, or installing a battery could unlock additional savings and new incentives.
Yes, but they will gradually decrease over time. The SRES rebate is scheduled to phase out by 2030, with the number of available Small-Scale Technology Certificates (STCs) decreasing each year.
State-based programs, such as rebates and interest-free loans, may also change or end based on government policy. However, new incentives, such as battery storage rebates and business solar tax benefits, are likely to emerge as Australia moves toward net-zero emissions. The best time to install solar and maximise rooftop solar incentives is now before rebates decline further.
