As more Western Australians switch to solar, the next big question is being asked more often: Are solar batteries worth it in WA?
It’s a fair question — battery storage doesn’t come cheap. And while solar panels often pay for themselves quickly (especially in sunny places like Geraldton), the value of adding a battery can depend heavily on your household’s usage and goals.
Let’s explore whether a solar battery makes sense for your home or business in 2025.
Harnessing the sun — this WA home runs on stored solar energy.
Why Consider a Solar Battery?
Solar batteries store the excess electricity your panels generate during the day so you can use it later — typically in the evening when energy usage tends to spike and the sun is no longer shining.
Without a battery, that excess solar is sent back to the grid. While you’ll receive a feed-in tariff for this exported energy, it’s often much lower than the price you pay to buy electricity back later in the day.
This is where solar batteries can begin to make financial sense.
If your household uses a lot of power at night — for example, to run air conditioning, charge an EV, or keep the house lit and running — a battery lets you keep and use your own solar power. That means greater savings, more control, and less reliance on energy providers.
The Financial Reality in 2025
So, are solar batteries worth it from a financial standpoint?
Prices have dropped in recent years, but they’re still a major investment — typically ranging from $7,000 to $15,000 depending on the system size, brand, and installer.
At the same time, feed-in tariffs in WA have fallen. This makes self-consumption more valuable than ever — and batteries help you achieve that.
You may find a battery to be worth it if you:
Use most of your energy in the evenings
Charge an electric vehicle overnight
Want backup power during outages
Plan to go off-grid or reduce grid reliance
However, if you’re home during the day and already use most of your solar in real-time, the financial return from a battery could take longer to materialise.
Do Batteries Pay for Themselves?
Generally, yes — but not as quickly as solar panels.
In 2025, most WA homes with the right usage profile can expect a payback period of 7 to 12 years on a battery system. That timeframe can vary depending on:
How much solar you generate
How much energy you use after dark
The size of your battery
Whether you’re on a time-of-use or flat electricity tariff
Batteries aren’t an overnight win — but they’re a long-term play that can improve energy independence and reduce bills over time. As tariffs evolve and grid costs continue to rise, the case for batteries may strengthen further.

Other Reasons Homeowners are Choosing Batteries
Not everyone asks “are solar batteries worth it” purely from a financial perspective.
Here are other common reasons WA homeowners are investing in storage:
Blackout protection: Keep essential appliances running during power outages (especially when paired with a hybrid inverter).
Reduced grid dependence: Particularly appealing in regional WA where outages and instability are more common.
Future-proofing: Many people install battery-ready systems so they can easily upgrade when costs drop further or new incentives become available.
Keeping track of solar savings and usage with live system data.
So are Solar Batteries Worth it in WA?
That depends on your goals.
If you’re focused purely on the fastest financial return, panels alone still offer the strongest payback. But if you want greater energy independence, use power heavily in the evenings, or want to future-proof your setup, then a solar battery may absolutely be worth it.
Many Geraldton homeowners are now choosing to install battery-ready systems, giving themselves the option to add storage later without needing to redesign their solar setup.
Final Thoughts
Solar batteries aren’t for everyone — but for more and more homes across Western Australia, they’re becoming a smart investment.
If you’re wondering whether a battery is right for you, your best move is to compare quotes from local solar providers. They can assess your usage habits, solar system size, and household energy goals — and show you the real numbers.
