What you need to know.

Over one million households in Australia have installed solar PV on their roof tops and received a financial benefit for doing so. The solar power rebates benefit comes in the form of Small-scale Technology Certificates (STCs).

Under the Small-scale Renewable Energy Scheme, eligible small-scale renewable energy systems may be entitled to small-scale technology certificates, which can be sold to recoup a portion of the cost of purchasing and installing the system.


Small-scale Technology Certificates (STCs) are created and monetised to provide financial incentives for installations of small-scale solar PV, small wind and micro-hydro systems, solar water heaters and heat pumps. Each STC represents one megawatt hour of electricity generated or displaced by renewable energy. These certificates are made available through the Small-scale Renewable Energy Scheme (SRES), which is one of two schemes under the Renewable Energy Target (RET) designed to help the Commonwealth Government achieve its target of sourcing 20% of energy from renewable sources by the year 2020.

System owners can apply for a number of STCs based on the size and type of system installed and their geographic location.The financial incentive received serves to reduce the upfront cost of the installation and enables a quicker return on investment for solar power rebates. Liable parties (typically electricity retailers) must purchase STCs and surrender them each quarter to meet the target set by the Regulator, thus creating a market based on supply and demand.

To be eligible for small-scale technology certificates and solar power rebates, small generation units must:

  • be installed no more than 12 months prior to the creation of certificates and have its panels and inverter listed on the Clean Energy Council list of approved components.
  • meet Australian and New Zealand standards
  • use a Clean Energy Council accredited designer and installer and meet the Clean Energy Council design and install guidelines
  • comply with all local, state, territory and federal requirements, including electrical safety
  • be classified as small-scale and a solar panel system that has a capacity of no more than 100kW and a total annual electricity output less than 250MWh.

The Renewable Energy (Electricity) Act 2000 and the accompanying Renewable Energy (Electricity) Regulations 2001 define the requirements of the SRES and the Large-scale Renewable Energy Target (LRET). The Act, Regulations, and scheme rules are administered by the Clean Energy Regulator, which is a regulatory body under the Department of Industry, Innovation, Climate Change, Science, Research and Tertiary Education (formally known as the Department of Climate Change and Energy Efficiency).

The Clean Energy Regulator administers the implementation of the SRES through the setting of STC liability targets, as well as validation, audit and site visits of installed renewable energy systems to ensure compliance with the scheme requirements. The Clean Energy Regulator also administers a Clearing House where certificates can be placed in a queue to obtain the clearing house price ($40) per certificate. In reality, the wholesale market is the active marketplace for the sale and purchase of certificates. However, liable parties have the option of purchasing certificates from the Clearing House if STCs are not available in the wholesale market.
