Solar battery rebates are a key reason why homeowners across Australia are choosing solar storage now. With federal incentives, installing a solar battery has never been more attractive for lowering power bills, increasing energy independence, and taking control of your energy future.
What’s Changed for 2026?
If you’ve been tracking solar battery rebates in Australia, you’ll know the Cheaper Home Batteries Program (federal government) has been a game-changer since its launch. Under this scheme, eligible batteries attract a discount through Small-scale Technology Certificates (STCs) which are essentially tradable certificates that fund part of the battery cost at the point of sale.
For 2026, there are important updates to how these rebates are calculated compared to 2025 especially around the STC factor and how rebates are applied based on battery size.
Lock in your battery rebates before they drop
Solar battery rebates are expected to reduce again soon. Explore our current battery deals and secure your rebate.
The STC factor determines how many certificates a battery earns per usable kilowatt-hour (kWh), which directly influences your rebate value.
In 2026:
January – April 2026: STC factor = 8.4
May – December 2026: STC factor = 6.8
This means that the later in the year your battery is installed, the fewer STCs it will earn and the smaller the rebate value will be. The installation date is what counts, so timing can make a big difference.
Battery Size & Tiered Rebates
Another major change from 1 May 2026 is how rebates are tiered by battery size. Rather than applying the STC factor equally across all battery capacities, the new rules use bands making smaller systems relatively more valuable under the rebate:
Battery Size (usable kWh) & Rebate Tiers
0 – 14 kWh: 100% of the STC factor
>14 – 28 kWh: 60% of the STC factor
>28 – 50 kWh: 15% of the STC factor
In simple terms, the first 14 kWh of your battery gets the full rebate value. Any capacity above that receives a reduced percentage, meaning larger batteries will attract less support per kWh added. This change is aimed at keeping incentives proportionate as battery costs fall and ensuring continued support across typical household systems.
Want to see exactly what this means for your own system? Check out our Solar Battery Rebate Calculator we’ve built it to reflect the May–December 2026 settings so you can plan ahead with transparency.
Will There Be More Changes in 2026?
As of now, no further changes are expected for the rest of 2026 according to current government modelling and our rebate calculator. This gives you a stable framework to plan with.
However, more adjustments are forecast for 2027, with the STC factor continuing to reduce every six months and potentially further tweaks to how rebates are applied through to 2030. That means delaying your install could significantly reduce your rebate. So if you’ve been on the fence, acting now could save you money.
Don’t delay – act now to secure the best rebate possible.
How to Qualify & Maximise Your Savings
To take advantage of solar battery rebates:
Your battery must be between 5 kWh and 100 kWh nominal capacity (but rebate applies only to the first 50 kWh).
It must be installed with new or existing solar PV.
The installer will generally apply rebates upfront as a discount so you don’t need to claim separately.
Why Now Is the Right Time to Act
Rebates won’t last forever.
STC values are declining every six months until at least 2030 meaning the sooner you install, the better.
Rebates for larger batteries are reducing faster, so early installs can save far more on bigger systems.
Getting your solar battery now not only lowers your upfront cost, it speeds up your path to energy independence, reducing reliance on the grid and lowering power bills over the long term.

Understanding rebates, STCs, battery sizing, and timing can be overwhelming especially when the rules are changing. That’s why we offer a Free Consultation to help you:
When is the right time to upgrade your solar system?
If your solar warranties are ending, it’s not something to ignore. If your electricity bills are rising, guessing your next step can be costly. A well-planned solar panel installation can lock in better savings and prepare your home for a battery – something that matters more than ever.
The best place to start is with a free consultation. It’s the fastest way to get clarity. You’ll understand what can stay, what needs replacing, and which rebates may apply.
If you’d like a quick estimate first, use our STC calculator.
This calculator is useful whether you’re upgrading solar panels or planning a full system refresh.
Should I replace my solar panels or add more?
This depends on three key factors: your goals, your roof, and the condition of your existing system.
When adding solar panels makes sense
Adding panels can be a smart option when your current system is still performing well. Many households use more electricity than they did when their system was first installed, particularly during the day.
Adding panels may suit you if:
Your existing panels are still producing well
You have spare roof space
Your inverter can support additional capacity
Adding panels can also be helpful if you plan to install a battery later, as more solar generation creates more surplus energy to store.
When replacing panels makes more sense
Replacing panels is often the better option when a system is nearing the end of its useful life or no longer suits how your home uses power.
Replacement may suit you if:
Your panels are old and output has noticeably dropped
You’re experiencing ongoing faults
You want a clean, new warranty setup
You want higher-wattage panels in the same roof area
A full replacement can also simplify system design and avoid performance issues caused by mixing old and new panels with different characteristics.
Why your inverter matters more than you think
Many solar upgrades are limited by the inverter. Older inverters often can’t support expansion and may restrict battery options.
A proper upgrade plan checks:
Inverter age and capacity
Monitoring and visibility
Battery compatibility
This is why a free consultation is important—it helps avoid investing in equipment that doesn’t suit your setup.
What happens to my existing solar panels?
Your existing panels don’t automatically become waste. In most cases, you have options.
Panels can be:
Kept if they’re still in good condition
Kept and expanded with a well-planned design
Removed and replaced if performance or compliance requires it
The right choice depends on safety, compatibility, and local network rules, which can vary across New South Wales.
Can I expand my existing solar system?
Yes but it depends on your requirements, roof space, and inverter capacity.
When expanding an existing system works well
Adding panels is usually a good idea when:
Existing panels still perform well
The upgrade is designed as one complete system
The inverter setup supports the final system size
Monitoring remains simple and clear
When expanding an existing system can cause problems
It may not be the best idea when:
Existing panels are heavily degraded
Old and new panels are mismatched in a way that limits output
Wiring becomes overly complex
Major compliance work is required regardless
A site check quickly clarifies which path makes sense.
Solar panel disposal
If panels need to be removed, disposal shouldn’t be your problem.
We remove panels safely and take them with us. You don’t need to organise transport or find a recycler. This makes the upgrade process simpler and reduces delays on installation day.
How to choose the right solar system upgrade
A better system isn’t just a bigger system. The best upgrade is one that matches how your household actually uses electricity.
Step 1: Understand how your household uses electricity
Review your electricity bill to find your average daily usage. Also note when you use power. Some homes use most of their energy during the day, while others use more in the evening. This difference directly affects the best upgrade path.
Step 2: Define your upgrade goal
Choose your primary outcome:
Lower electricity bills
Higher self-consumption
Battery readiness
Backup support for key circuits
Each goal changes the system design. For example, bill reduction often involves more solar with a battery plan, while backup support requires a battery capable of outage protection.
Step 3: Check roof Space, orientation, and shade
Roof space and orientation matter, and shade matters even more.
These tools help you compare options before committing.
Step 5: Get Expert Advice Before You Commit
This is where many costly mistakes are avoided.
We review your bills, discuss your goals, check your roof and recommend an upgrade path that fits your home. If you want the fastest next step, book a free consultation for clear advice and transparent numbers.
Do I need to add solar batteries?
If your goal is greater savings, a solar battery is often the most effective upgrade. It allows you to use more of your own solar energy and reduces reliance on the grid at night.
Why batteries can increase savings
Without a battery, excess solar is usually exported at lower feed-in rates. A battery stores daytime solar so you can use it in the evening, reducing grid imports during higher-cost periods.
Batteries are especially useful if:
Your household uses more power after sunset
You run air conditioning in the evening
You cook with electric appliances at night
You charge an EV at home
You want to reduce peak grid imports
Solar Battery Rebates and Incentives
Battery rebates can significantly reduce upfront cost and improve payback.
Battery vs more solar panels: Which upgrade adds more value?
If your roof is close to full, a battery can add value without installing more panels.
Even with spare roof space, additional panels may increase exports rather than self-use. A battery converts those exports into evening energy, which is why batteries are now a key part of many solar system upgrades.
