Already have solar? You may be able to get more out of it by adding panels, replacing an old inverter or adding a battery to a system that never had one.
A common sign
“We put solar on years ago and I’m not sure it’s doing much anymore.”
About solar and battery upgrades
The inverter is usually the first part of a solar system to wear out, often well before the panels. Replacing it can bring a system back to full output. Adding panels can help if you now use more power than when the system went in.
Adding a battery to an older system is common too, but not every inverter works with every battery. A specialist can check what you have and tell you what will work with it.
Older solar systems producing less than they used to
Households using more power than when solar was installed
Adding a battery to existing solar
Ask for a check of what you already have before any upgrade is quoted. The right upgrade depends on your inverter, your panels and how you use power now.
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.
Panels, inverter and the wiring to the board. The size that suits you depends on when you actually use power.
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.
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.
