Solar Hot Water Systems Sydney
Solar hot water uses the sun to do most of the heating, with a gas or electric booster for cloudy stretches — the lowest running cost of any system when your roof suits it. We supply, install and repair solar across Sydney.
Solar hot water, done right for your roof
Good solar hot water Sydney installs start with the roof, not the brochure. A solar hot water system sydney homeowners actually benefit from begins with roof aspect and shading. On a good north-facing, unshaded roof a solar system has the lowest running cost of anything on the market; on a poor roof it can underperform, which is why we assess suitability before recommending it. We supply and install roof-mounted (close-coupled) and split solar systems, and we also handle solar hot water repairs on existing units.
Every solar system has a gas or electric booster that tops up the heat when the sun can't, so you never run cold — we size that booster to your household. Where solar doesn't suit the roof, we'll tell you honestly and show you a heat pump instead, which often gives similar running costs with more flexibility on placement.
And because eligible solar systems can attract government incentives, we confirm any rebate and apply it to your quote.

What decides whether solar suits your home
Solar is brilliant on the right roof and underwhelming on the wrong one. These are the things we weigh with you.
Roof aspect & shading
North-facing, unshaded roof space gives the best result. We assess this before recommending solar so you don't pay for a system the roof can't feed.
Close-coupled vs split
Close-coupled puts the tank on the roof with the collectors — efficient and simple. A split system keeps the tank at ground level, which suits some roofs and looks better on others.
Household size & booster
Larger households that use plenty of hot water get the most back. We size the gas or electric booster so cloudy days never leave you cold.
Solar vs heat pump
On a poor roof or a smaller home, a heat pump often matches solar's running cost with more placement flexibility. We compare both honestly before you commit.
Lowest running cost on the right roof — booster-backed so you never run cold.
How much solar costs, and how long it lasts
What solar costs, how long it lasts, and what we repair.
Solar hot water costs more upfront than a basic electric tank, but far less to run — and on a suitable roof that gap pays back over the system's life. A well-installed and maintained solar system typically lasts a long service life, with the collectors and tank the long-lived parts and the booster, controller and valves the items we check over time. We quote the installed price on your actual roof and site, and show any rebate taken off.
If you already have solar and it's underperforming, that's usually a booster, controller, valve or sensor issue rather than the collectors — all of which we repair. A quick diagnosis tells us whether it's a cheap fix or time to consider a replacement.
