Small Scale Technology Certificates - STCs

What is an STC?

Ecovantage is authorised to create Small-scale Technology Certificates (STCs) for eligible solar water heaters, air source heat pumps, small-scale solar panels and wind or hydro systems following installation. If you install an eligible system, you are entitled to a financial incentive relative to the amount of electricity generated or saved.

One STC is equivalent to 1MWh (megawatt hour) of:

  • renewable electricity generated by small-scale solar panel, wind or hydro system, or
  • electricity displaced by the installation of a solar water heater or air source heat pump.

What is the current STC price?

As the scheme is market-based, the STC price can change on a weekly or monthly basis.

Call us on the number below and we can give you a current price and answer any other questions you have about claiming the rebate.

How long do I have to claim an STC rebate?

You can claim STCs after your system has been installed. You have 12 months after the installation date to lodge and have your claim processed.
