Register of Solar Water Heaters


The register of solar water heaters is a list of the solar water heaters and air source heat pumps that are eligible under the Small-scale Renewable Energy Scheme (SRES).

Under the Renewable Energy (Electricity) Regulations 2001, the register of solar water heaters contains information about each solar water heater and air source heat pump model that is eligible for small-scale technology certificates (STCs). The number of STCs a particular model is entitled to will depend on its installation date and geographic location.

To determine how many small-scale technology certificates a hot water system may be entitled to, applicants must use the method developed by the Clean Energy Regulator, which is outlined in the Renewable Energy (Electricity) Regulations legislative instrument.

Based on this method, the Clean Energy Regulator has published template deck files to assist manufacturers with product modelling process. The Clean Energy Regulator will not accept calculations based on other methodologies.

The number of small-scale certificates a system is eligible for is based on the life of the system – current deemed at ten years.

The 2020 application dates are:
- Version 40: Opened 2 March and closed 1 April 2020
- Version 41: Opened 1 July and closed 31 July 2020
- Version 42: Opens 12 October and closes 11 November 2020​

Who Can Apply?

Eligible applicants include solar water heater manufacturers.

Please refer to the website or contact the program administrator for the complete eligibility requirements.

Eligible Activities

Eligible solar water heaters includes:
- Air source heat pumps with a volumetric capacity of no more than 425 L.
- Solar water heater models with a capacity of:
a) Less than 700 L (mostly domestic models).
b) More than 700 L (mostly commercial models).

To be listed on the register, all solar water heaters and air source heat pumps must be certified to Australian and New Zealand Standard 2712:2007. Compliance with the standard must be demonstrated by providing the Clean Energy Regulator with an Australian and New Zealand Standard 2712:2007 licensing schedule that identifies all of the models they wish to have listed on the register.

The Clean Energy Regulator will not accept submissions for products that do not have Australian and New Zealand Standard 2712:2007 certification. All models submitted must be certified by the application closing date or the submission will not be accepted. The Clean Energy Regulator strongly recommends manufacturers speak with their conformity assessment body well in advance of the application closing date.
