Hot Water Systems

Solar hot water systems absorb the energy from the sun to heat water. Heat pump hot water systems draw heat from the air to heat water.

Under the Small-scale Renewable Energy Scheme eligible solar water heaters and heat pumps are entitled to a number of Small-scale Technology Certificates (STCs). This is based on the estimated amount of electricity in megawatt hours (MWh) the system displaces over the course of its lifetime. The number of STCs a particular SWH model is entitled to create will depend on its installation date and geographic location identified through its postcode.

Your STCs can be assigned to a registered solar water heater Agent (such as a retailer or installer) in exchange for a financial benefit, such as a discount off your invoice.
