Get a Free QuoteHow much do solar systems cost?
It depends on your usage, roof and whether you add a battery, so we don’t sell packages. After a free assessment you get a fixed written quote.
How long do solar panels last?
25 years or more. Most panels carry a 20–25-year performance warranty; our workmanship warranty is 10 years.
Do I need battery storage with my solar panels?
Not essential, but often worth it for blackout backup and using your own solar after dark. We check your usage first.
How long does solar panel installation take?
Most homes are finished in a day; larger systems and batteries take up to three. Your proposal includes a firm timeline.
What maintenance do solar panels require?
Very little: an occasional clean and an annual check.
Can I add more panels to my system later?
Often, if there’s roof space and inverter capacity. Tell us early and we’ll leave room to grow.

Which state is your home in?
Do you own your home?
Unfortunately, we only work with homeowners
If you are considering solar for a new home, or on behalf of someone else, select "I own my home"
We only work with homeowners
A solar or battery system is a permanent change to the property, so it needs to be arranged by the person who owns the home.
If you tapped that by mistake, head back and we'll pick up where you left off.
What are you looking for?
Our team can talk you through all options if you're not sure.
What appeals to you most?
You'll get all of these. We'd just like to know what matters most.
How much is your quarterly electricity bill?
The average Adelaide home spends $500 - $1000 per quarter. Not sure of yours? Take your best guess, we'll go through the real numbers at your assessment.
Whatever it is today, our goal is $0. If we don't get you there, we'll pay your bill.
How soon are you looking to get a system installed?
We can work with you on a longer timeline, or get you saving as soon as possible.
What is your address?
We have hundreds of happy customers across South Australia. We need your address to check we service your area and to look at your roof before we visit.
Great news, we service your area!
Anything else to share?
Every system we design is tailored to the home, so the more info the better! (Optional)
How should we get in touch with you?
Last step. We'll call to arrange your free on-site assessment at a time that suits you. No pressure and no obligation.
