If you’re a homeowner in Victoria considering a solar battery installation, 2025 is shaping up to be a crucial year. Federal Small-scale Technology Certificates (STCs) — the incentives that reduce the upfront cost of solar and battery systems — are continuing to decline each year. This reduction directly affects how much you can save on your installation. The earlier you act, the more you can potentially claim.
With increasing electricity prices and more Victorians switching to clean energy, understanding how STCs work and why timing matters can help you secure maximum value for your investment. This blog breaks down everything you need to know and why now is the right time to lock in your savings.
What Are STCs and Why Are They Dropping?
STCs are part of Australia’s Renewable Energy Target (RET). When you install a solar or battery system, you’re eligible to receive a set number of certificates based on system size, postcode zone, and year of installation. These certificates are then sold to energy retailers, which reduces the cost of your system.
However, STCs decrease every year until the scheme ends in 2030. This means:
- Fewer certificates issued
- Less financial benefit
- Higher net installation costs for homeowners
Each year the government reduces the deeming period — the number of years your system is assumed to generate renewable energy. As the deeming period shortens, the number of STCs drops. By 2025, households will receive fewer STCs compared to previous years, making early action even more important.
What Does the 2025 STC Drop Mean for Victoria Homeowners?
Victorians are in a unique position because the state already enjoys strong renewable energy adoption, generous local rebates, and a high demand for battery storage. But as federal STCs fall, the total incentive stack also shrinks.
In practical terms, this means:
- Higher upfront costs for battery installations
- Reduced overall rebate value, even with state programs
- Longer payback periods if installation is delayed
- More competitive installer schedules, especially toward year-end
For homeowners planning to install batteries in late 2024 or throughout 2025, the earlier you confirm your installation, the more STCs you can still access. Waiting too long can cost hundreds — and in some cases, even thousands — of dollars.
Why Batteries Are Becoming Essential in Victoria
Victoria is one of Australia’s fastest-growing renewable energy adopters. With frequent grid challenges, rising power bills, and evolving state energy reforms, batteries are no longer a luxury — they’re a smart investment.
Key reasons more Victorians are choosing battery storage include:
1. Protection Against Rising Electricity Prices
Electricity rates in Victoria have surged significantly over the last few years and are projected to rise further. A battery system helps homeowners store excess daytime solar energy and use it at night when tariffs peak.
2. Enhanced Solar System Performance
With a battery, you maximise the use of your solar generation rather than exporting it at low feed-in tariffs. This significantly increases your return on investment.
3. Backup Power During Outages
Victoria’s unpredictable weather and network faults can cause outages. A battery with backup capability ensures your essential appliances stay powered.
4. Federal and State Savings
When combined with the Victorian Government’s incentives, early-year installations allow homeowners to take advantage of both state rebates and higher federal STC benefits.
Why You Should Act Before the STC Reduction Takes Effect
A declining STC value is something you cannot control — but your timing is. Installing in early or mid-2025 ensures:
- You receive the maximum possible STC rebate before the deeming period drops again.
- Installers still have better availability, avoiding year-end congestion.
- Prices are generally more stable, as demand surges usually push installation costs up.
- You lock in your energy independence earlier, reducing your ongoing power bills.
The longer you wait, the fewer STCs you qualify for — and the higher your investment becomes.
