How Does Solar Rebate Work for Victorian Homes?

Key Takeaways

• The Small-scale Renewable Energy Scheme (SRES) provides an upfront discount, in the form of Small-scale Technology Certificates (STCs), on solar systems.
• STC declines in value every year, meaning there is a slightly smaller federal rebate for solar panels in 2025 compared to last year.
• The state’s Solar Homes program continue to offer a point-of-sale rebate of up to $1,400 for solar PV installations. This covers up to 50% of the post-STC system cost, capped at $1,400 per household.
• Since the federal STC discount shrank, Victorian households ended up utilising the full $1,400 in most cases.
• Victoria’s interest-free solar battery loan was available in 2024. It is now replaced by the Cheaper Home Batteries program starting July 1st.

Introduction

The net cost of adding battery storage dropped significantly in 2025 thanks to the new federal subsidy. Many Australian households already have solar panels, but less than 5% of those have a home battery.

Since the Renewable Energy Scheme’s Small-scale Technology Certificates’ (STCs) value declines per year, many homeowners find themselves maximising the $1,400 solar panel discount from Solar Victoria.

A major development in 2025 was the introduction of the federal Cheaper Home Batteries program, which started just this July. This scheme provides an upfront subsidy of roughly 30% off a home battery’s cost. In practice, this equates to about $4,000 off a typical 11–13 kWh battery system.

More importantly, this federal battery rebate can be claimed on top of the Victorian solar panel rebate.

Scenario 1: System Cost without Battery

The table below illustrates a sample cost breakdown for a typical 6.6 kW residential solar PV system in Victoria, comparing 2024 vs 2025. The example assumes a gross system price of roughly $8,000 for a good-quality 6.6 kW solar setup.

Federal STC incentives and the state rebate are then applied to show the out-of-pocket cost to the homeowner in each year. We used the STC calculator provided by the Clean Energy Regulator to approximate the STC incentives.

The assumption in 2025, with 6 years remaining to 2030, the STC refund is ~7% lower.

The Victorian Solar Homes rebate covers 50% of the remaining cost up to $1,400 – here we assume the full $1,400 is utilised both years.

Actual system prices and STC values may still vary. This example shows that a homeowner’s net cost for a 6.6 kW system slightly rose due to the reduced federal rebate. Thanks to the combined federal and state incentives, the out-of-pocket cost for a new system remains well under half of the pre-rebate price.

Scenario 2: System Cost with Battery Storage

We show here a sample package combining the same 6.6 kW solar PV system with a home battery 10 kWh capacity, again comparing 2024 vs 2025.

The example assumes a battery gross cost around $8,800 (typical for a ~10 kWh battery installed).

Note that in 2024 there was no federal battery rebate, whereas in 2025 the new federal program contributes 30-40% off the battery cost. This scenario illustrates the dramatic reduction in battery system pricing in 2025 relative to 2024.

Table 2: Example 6.6 kW Solar + 10 kWh Battery System

The 2025 scenario includes an estimated ~$3,440 federal battery rebate, which corresponds to ~10 kWh of usable storage at ~$344/kWh. In both years, the Victorian panel rebate cuts $1,400 off the PV cost.

As shown, the total out-of-pocket cost for a 6.6 kW solar + 10 kWh battery package in 2025 is less than the 2024 cost in this example. This is primarily due to the new federal battery subsidy. This huge improvement is an excellent time for Victorians to invest in adding battery storage.

Final Thoughts

The federal and state rebates still prove to be effective in making complete solar and battery systems affordable. For a household that only wants solar panels, the incentives in 2025 still cover a large portion of the cost. That’s around 40–50% of a typical system’s price through STCs and the Solar Victoria rebates combined.

For those interested in solar batteries, this year’s new federal program is a game-changer. It bridges much of the cost gap that previously made batteries expensive.

Many Victorians who installed solar without a battery in past years can now retrofit a battery at a far lower net cost than was possible in previous years. The combined rebates and incentives allow the solar panels and batteries altogether to be more attainable.

Finally, it’s worth noting that most solar providers let customers decide on adding a battery as an optional extra. It reflects the reality that most Australians have gone solar, but haven’t installed batteries yet.

Frequently Asked Questions (FAQs)

Q: How does the solar rebate work in Victoria for solar batteries?

A: In Victoria, homeowners can access both state and federal battery rebates. In 2025, this means a typical 10kWh battery could receive a combined rebate of up to $7,000, drastically reducing upfront costs. You simply choose an accredited installer, and the rebates are applied as a discount on your invoice.

Q: What is the 20% rule for solar panels?

A: The 20% rule refers to solar panel efficiency. A 20% efficient solar panel converts 20% of sunlight into usable electricity. Most modern panels range from 17–22% efficiency, and this impacts how many solar panels you’ll need to meet your household needs.

Q: How do I claim or apply for solar rebate in Victoria?

A: To claim a solar rebate, select an accredited installer who participates in the Solar Homes Program or federal rebate schemes. Your installer will guide you through the eligibility process and handle paperwork.
