How to decide if solar battery storage makes sense for your home in 2025
So you’ve got solar — or you’re thinking about it — and you’re wondering:
Is it worth getting a battery now, or should I wait?
At Solar You, this is one of the most common questions we get. And the answer isn’t one-size-fits-all. But with the new WA government battery rebate of up to $5,000, it’s a better time than ever to consider it seriously.
Let’s break it down simply.
🔋 What does a solar battery actually do?
A battery stores excess solar power your panels generate during the day, so you can use it at night or during a power outage.
That means:
- You use more of your own solar energy
- You buy less from the grid, especially during peak rates
- You get more independence from rising electricity prices
- You can potentially back up key appliances if the grid goes down
🏡 Why you might get a battery now
✅ You use most of your power in the evening
If your home is quiet during the day but buzzing at night, a battery lets you use your solar when you actually need it.
✅ You want blackout protection
Some batteries (like Tesla Powerwall or Sungrow) offer backup power for lights, fridges, internet, or even air con during outages.
✅ You want to maximise your solar investment
With feed-in tariffs (what you’re paid for sending power to the grid) getting lower, it makes more sense to store your own power than export it.
✅ You qualify for the WA battery rebate
As of 2025, eligible WA homeowners can get up to $5,000 off a battery system under the Battery Energy Storage System (BESS) scheme.
✅ You’re planning for an EV
A battery can store solar power to charge your car overnight, saving even more long-term.
🕐 Why you might wait
⏳ You’re on a tighter budget right now
Even with the rebate, a battery is a significant investment (typically $6,000–$12,000 after incentives). If your budget is tight, starting with solar alone is still a great move.
🧰 Your home’s energy usage is low
If you don’t use much power at night, your battery’s payback time will be longer.
🛠️ You want to see how prices and tech evolve
Battery prices are gradually dropping, and newer features (like vehicle-to-home charging) are on the horizon. If you’re not in a rush, you can keep an eye on the market.
⚙️ Can I add a battery later?
Absolutely. If you’re not ready now, we can design your solar system to be battery-ready, so it’s a simple add-on in the future — no extra costs or rework.
✅ So, should you get one now or later?
Here’s the quick summary:
You should consider a battery now if… | It might be better to wait if… |
---|---|
You use lots of power in the evening | Your power bills are already low |
You want blackout protection | Budget is your main concern |
You qualify for the $5,000 rebate | You’re waiting on future tech |
You want to reduce grid dependence | You just got started with solar |
