Panels only generate while the sun's up. Without storage, every kilowatt-hour you don't use in daylight gets exported for a few cents and bought back later at several times the price. On a typical export tariff, a household selling power for around 4c to 6c a kilowatt-hour can pay 30c or more to buy it back that same evening. Here's where battery actually fits.
The Two Edges
Solar only
Great during daylight hours, but every evening you're back on the grid at full retail rate, including the power your own panels made hours earlier. Result: bill drops during the day, climbs straight back up at night.
Fully off-grid
Right for a property the grid never reached, or complete independence, but it needs significantly more battery capacity and usually backup generation. Result: higher upfront cost, no monthly bill at all.
The Middle Ground
Solar plus battery
Daytime power gets stored instead of exported for a few cents, then used that same evening at no additional cost. The grid becomes a backup, not your main supplier — most households see 0–5% grid draw from month one.
Here's how we get from your evening usage pattern to a battery that actually matches it.
We model your actual overnight usage, not your total daily consumption — that's what the capacity decision should really be based on.
We assess your existing inverter and panels (if you have solar already) before recommending a compatible battery, rather than assuming a full replacement is needed.
Your Cheaper Home Batteries Program rebate is calculated and applied as an upfront discount, then installed by our own accredited crew.
The most common battery mistake is buying more capacity than a household will ever draw down overnight, or too little to get through til morning.
We look at when you actually draw power overnight, not just your total daily usage, so the capacity you buy gets used rather than sitting half full.
Adding a battery to a system we didn't originally install is common. We assess your current inverter and panels before recommending a compatible battery.
Virtual Power Plant programs can add extra income by letting your battery support the grid at peak times, but enrolling is entirely your call.
Feed-in tariffs, the rate retailers pay for power your solar exports, typically sit somewhere between 4c and 8c per kilowatt-hour depending on your retailer and state. Buying that same amount of power back once the sun goes down can cost 30c or more per kilowatt-hour on a standard plan. A battery doesn't change either of those rates. It simply lets you use your own cheap power instead of selling it low and buying it back high.
Federal battery incentives are assessed against your specific system's capacity rather than a flat figure, which is why the rebate range varies depending on how many kilowatt-hours of storage you install. We calculate your exact eligible amount during the free audit and apply it as an upfront discount, the same way we handle STC certificates on a solar install.
You don't need to have installed your solar with us to add a battery through us. We assess your existing inverter, panel configuration and any warranty conditions before recommending a battery that's actually compatible, rather than assuming a full system replacement is required. In some cases a hybrid inverter swap is the more cost-effective path than people expect.
A Virtual Power Plant, or VPP, is a program where your battery can support the wider electricity grid at times of high demand, in exchange for additional payments or credits. It's an optional layer on top of the battery itself, not a requirement to get one installed, and we'll walk you through what it would mean for your specific battery and retailer if you're interested.
The most common battery mistake we see isn't a bad brand choice, it's the wrong capacity for how a household actually uses power overnight. Too small and you're back on grid power by midnight. Too large and you've paid for storage that rarely gets drawn down. Our audit models your actual evening usage rather than your total daily consumption, which is what the capacity decision should really be based on.
