Solar panels turn sunlight on your roof into power for your home. The more of that power you use yourself, the less you buy from the grid.
A common sign
“Our power bill keeps going up and we’ve got a big empty roof.”
About rooftop solar installation
A solar system is the panels on your roof, an inverter that turns their power into the kind your home uses, and the wiring that connects it to your switchboard. Whatever your home doesn’t use is sent to the grid.
Power you use yourself is usually worth more than power you send back, so it pays to run things like the dishwasher, washing machine or hot water during the day. A good installer will look at your roof, your shading and your bills before recommending a size.
Rising power bills
Big daytime power use, like pools or air conditioning
Homes planning a battery or EV later
Ask how the system is sized to your household, not just to your roof. And ask what happens if you add a battery or an EV down the track.
Not sure where to start?
Don’t waste money on upgrades you don’t need. A professional home energy assessment shows where your house loses heat and power, so your budget goes where it makes the biggest difference.

More in solar and batteries
Make your own power, keep the lights on through an outage, and get more out of a system you have already paid for.
Stores what the roof makes in the day for the evening, and keeps the lights on in an outage if it is wired for it.
Adding panels, replacing an ageing inverter, or fitting a battery to a system that never had one.
Connects your home battery to a virtual power plant, which can pay you for letting the grid draw on it at busy times. Some battery rebates require it, so ask before you choose a battery.
Solar panels, batteries and usually a backup generator, sized to run the home with no grid connection at all. Most common on rural blocks a long way from the poles.
Panel cleaning, output checks and isolator faults. A system quietly underperforming for years is common.
