How Does a Solar Hot Water System Work?
Solar hot water systems use roof-mounted collectors to absorb energy from the sun and heat the water stored in a dedicated cylinder, as close-coupled (tank and panels on the roof) or split (tank on the ground) setups.
A gas or electric booster guarantees continuous hot water on overcast days. Solar delivers the lowest running costs of any system, backed by rebate programs.
Best for: North-facing roofs and homeowners planning to stay long-term to maximise return on investment.

Solar can supply up to 90% of a household’s hot water from free sunlight, cutting hot water running costs to near zero — the lowest of any system type.
Close-coupled mounts the tank and panels together on the roof; split keeps the tank at ground level with only the panels on the roof — tidier and easier to service.
