Do I need a home battery? A straightforward way to decide

Solar panels make electricity while the sun is up. If most of your use is in the evening (cooking, heating, the TV, charging devices), that's the electricity a battery can cover.

A battery is likely worth a look if…

• Your household is out during the day and home in the evening.
• You pay a high price per kWh and get a low feed-in credit for solar you send to the grid.
• You already have solar and your bill shows you export a lot during the day.
• You're planning an electric car, a heat pump or electric heating.

Solar alone may be enough if…

• Someone is home during the day and uses most of the solar as it's made.
• Your electricity use is low overall.

What about blackouts?

Many people assume a battery keeps the lights on in a power cut. It only does if chosen circuits are wired to it for backup. With RENUABL that's an optional extra called Blackout Backup, and which circuits to back up (the fridge, lights, internet) is agreed on your call.

How we size it

We look at how much you use after dark on a typical winter day and choose the smallest battery that stores it, with panels big enough to charge it. You'll never be asked to choose a battery size yourself.

Savings from a battery depend on your usage and electricity plan. Your price shows the estimate for your home, and the federal battery incentive is taken off it.
