What Does Solar Hot Water Installation Cost?
There's no single price — it comes down to the system, your roof and the install. Here's how we quote it, fairly and clearly.
The cost to install a solar hot water system in Brisbane or on the Sunshine Coast depends on the type of system, the tank size your household needs, and how involved the installation is on your roof. A close-coupled roof system installs differently to a split system with a ground-level tank, so the fairest way to price it is to look at your actual home.
That's exactly what we do. Every quote is all-inclusive — the system, licensed installation of the collectors and tank, valves, boosting, removal of your old unit and GST — with no hidden extras. And if a repair or a different system makes better sense for your budget, we'll tell you honestly.
4 Things That Shape Your Solar Install Quote
Understanding these helps you compare fairly — and we'll explain exactly how they apply to your home.
System Type
Thermosiphon (tank on the roof) and split systems (tank on the ground) install differently and sit at different price points.
Roof & Collector Access
Roof pitch, height, tile versus metal and how easy the collectors are to reach all affect the labour in an install.
Tank Location
On a split system, running lines to a ground-level tank adds work; a close-coupled roof tank is more straightforward.
Changeover & Compliance
Removing the old system, new valves, boosting and any compliance upgrades are all part of a proper installation.

FAQs
Solar Hot Water Installation Cost — FAQs
How much does solar hot water installation cost in Brisbane or the Sunshine Coast?
What's included in a solar hot water installation?
Our quotes are all-inclusive: the system itself, licensed installation of the collectors and tank, valves and fittings, boosting connection, removal and disposal of your old unit, and GST. We confirm everything before we start so there are no surprises on the day.
How long does a solar hot water installation take?
Most solar changeovers are completed within a day by our licensed local technicians. A split system with a ground-level tank can take a little longer than a close-coupled roof system — we'll confirm the timeframe when we quote your job.
What's the difference between thermosiphon and split solar installs?
What happens on cloudy days?
Every solar system we install includes an electric or gas booster that automatically tops up the water temperature when there hasn't been enough sun, so you always have reliable hot water.
