Solar hot water Sydney: roof mounted and split systems with rebates
Solar hot water systems Sydney homes install today pair evacuated tube or flat plate collectors with an electric or gas boosted tank. We assess roof pitch, orientation and shading so your solar hot water Sydney system carries the household through most of the year on sunlight alone.
We handle federal STC and NSW Energy Savings Scheme paperwork so the rebate comes off your invoice at point of sale, and we repair existing solar hot water Sydney systems including pumps, controllers, boosters and collector leaks.
Roof mounted versus split system solar
A close coupled roof mounted system puts the tank on the roof above the collectors and runs on thermosiphon, so there is no pump and very little to fail. It is the most reliable configuration, but it needs a roof structure that can carry the load and many owners dislike the appearance.
A split system keeps the tank at ground level and circulates fluid with a small pump and controller. It looks better, suits heritage and two storey homes, and is easier to service, at the cost of two more components that eventually need attention. Both configurations perform well on Sydney and Central Coast solar radiation.
Realistic savings and rebate treatment
Well sited solar hot water covers the majority of a Sydney household's annual demand, with the booster carrying the shortfall through the shortest winter weeks and long overcast runs. Coastal salt exposure, shading from a neighbour's tree and roof orientation change that number more than brand choice does, which is why we assess the roof before quoting.
Federal small scale technology certificates and NSW Energy Savings Scheme incentives are applied as a discount on your invoice, so you are not out of pocket waiting on a claim. We also repair existing solar systems, including pumps, controllers, boosters, sensors and collector leaks, rather than automatically recommending replacement.
