Renewable Energy Certificates

The measurement of renewable energy that can be traded or sold is called a Renewable Energy Certificate. For an obligation free assessment & consultation click below.

Australia’s Renewable Energy Target (RET), requires energy retailers to purchase a set amount of certificates each year, so there is a constant demand for these certificates.

You can be eligible to create certificates under either:

  • The Small-scale Renewable Energy Scheme (SRES), for systems under 100 kW. This is the scheme that applies to residential solar PV system.
  • The Large-scale Renewable Energy Target (LRES), for systems above 100 kW.

Small-scale Technology Certificates (STCs)

STCs are provided under the SRES, and help reduce the upfront cost of installing your solar PV system.

STCs are an electronic form of currency and are allocated to you when you install a solar PV system. One STC is equivalent to one megawatt-hour of electricity generated by your solar PV system.

The price of STCs changes according to market conditions. The total level of subsidy you receive will depend on a number of factors, including the location and size of the solar PV system and the price of STCs at the time the system was installed.

There are two ways you can be paid for your STCs:

  • Assign your STCs to a registered agent in exchange for a financial benefit when you purchase your solar PV system. This benefit may be in the form of a delayed cash payment or an upfront discount on your solar PV system (most consumers take this option).
  • Create the STCs yourself by finding a buyer and then selling and transferring them in the Renewable Energy Certificate (REC) Registry.

For more information, contact the Clean Energy Regulator.

What size subsidy will I receive?

Australia is divided up into zones based on how much renewable energy can be generated by a solar panel in a given area.

A system installed in Melbourne or Hobart (zone 4) receives fewer STCs than the same sized system installed in Sydney (zone 3) or Darwin (zone 2). This is because Melbourne and Hobart receive less sunshine, so less solar energy is produced by the system.

You can use the REC Registry calculator to determine your approximate level of subsidy.
