Why A Battery Now
Exporting Your Solar Earns 2 Cents. Using It After Dark Saves 32. That's The Case For A Battery.
If you've watched your Synergy bill climb, the maths now firmly favours storage. DEBS pays just 2c/kWh for solar exported outside the 3–9pm window — but every stored kWh you use in the evening saves you around 32c. A battery turns your midday surplus into your evening power, and three layers of government support still bring the price down:
- WA Residential Battery Scheme — Up to $1,300 (Synergy) or $3,800 (Horizon Power) off an approved battery. 100,000 rebates state-wide, available until the allocation runs out.
- Federal Cheaper Home Batteries Program — Around 30% off upfront cost, currently worth roughly $2,500–$2,700 on a 10 kWh system. The rate now steps down every six months — the next reduction lands 1 January 2027.
- WA No-Interest Loan Via Plenti — $2,001–$10,000 over 3–10 years at 0% interest for eligible households.
How Your Battery Works
(Without Jargon)
A home battery stores the solar your panels produce during the day so you can use it after sundown, when grid electricity is most expensive.
Your Panels Generate Solar All Day
Perth averages 5.8 peak sun hours, one of the highest solar irradiance levels of any capital city. A 6.6kW system makes more than most homes use during daylight hours.
Surplus Solar Charges Your Battery, Not The Grid
Without a battery, that surplus flows to the grid for 2.25–10c per kWh. With a battery, it charges the unit directly, typically fully charging a 10 kWh battery by early afternoon.
Your Home Runs On Stored Solar After Sunset
From dusk through the evening peak (3pm–9pm) when grid electricity is most expensive, your home draws from the battery instead of Synergy. Each kWh used this way saves you around 30 cents.
Grid Is Backup, Not Default
On the rare day where you run the battery flat, the grid tops you up automatically. You don't notice the handover.
During A Blackout, Your Battery Keeps The Lights On
With a backup-ready battery (Tesla Powerwall 3, Sigenergy, BYD with backup box), essential circuits keep running while the grid is down.

What A Battery Actually
Does To Your Bill
Across our 45,000+ installations, Perth households combining solar with battery storage typically see bill reductions of 70–90% — transforming electricity from a major expense into a near-negligible one.

Full Rebate GuideA Battery
Is A Great Fit If
Here's what makes a battery a good investment for your home.
Good Fit
- You already have solar, or you're adding solar and a battery together
- Your Synergy bill regularly exceeds $400/quarter
- You use a meaningful amount of power after 3pm (families, home-based workers, EV owners)
- You own your home (the rebate requires owner-occupier or landlord consent)
- You're on Synergy (SWIS) or Horizon Power
Worth A Conversation First
- You're away during the day and evenings — you may not cycle the battery hard enough
- Your roof is heavily shaded or poorly oriented — solar sizing matters for battery value
- You're planning an EV purchase in 12 months — battery sizing should account for it
- You're a renter or strata property — rebates and technical approvals need upfront planning
What A Virtual Power Plant
Actually Means For You
To claim the WA battery rebate, your system must join a Virtual Power Plant (VPP). Here's what that means in plain English.
A network of home batteries — thousands of them — that Synergy or Horizon Power can call on during peak grid stress. Instead of firing up a gas peaker, the grid pulls a bit of stored energy from each participating battery.
