Already Have Solar? Here’s What You Need to Know Before Adding a Battery
Already have solar on your roof?
Then you’ve done the hard part. Now comes the interesting question:
What happens to the solar energy you don’t use?
For many Queensland homeowners, adding a battery can be the next step towards using more of their own energy and relying less on the grid.
But before you add a battery to an existing solar system, there are a few things worth checking.
Will a battery work with your existing solar?
In many cases, yes.
However, your current inverter, solar system size, switchboard and electrical setup will determine the best way to integrate battery storage with existing solar panels.
Sometimes it’s a straightforward retrofit. Other homes may benefit from upgrading parts of the existing system.
Compatibility first. Battery second.
How big should your battery be?
Bigger isn’t automatically better.
If your solar system regularly produces excess energy during the day, a battery can store some of it for the evening – when your home may need it most.
Your ideal size depends on your solar production, evening consumption and future plans.
Adding an EV? A pool? More air conditioning?
Those details matter.
What about your inverter?
This is where good system design becomes important. Depending on your existing equipment, a solar battery retrofit in Australia may use your current inverter or require a different configuration.
The goal shouldn’t be to simply make a battery “work”. It should work beautifully with the system you already have.
Is adding a battery worth it?
If you’re exporting plenty of solar during the day and buying electricity back from the grid later, existing solar battery storage could be worth exploring.
But every home is different.
At Weglow, we assess your existing solar, energy consumption and future needs before recommending a battery retrofit in Queensland.
You’re already generating your own energy. Maybe it’s time to keep more of it.
