Under the SRES, eligible solar systems are awarded Small-scale Technology Certificates (STCs) based on the amount of renewable energy they are expected to generate over a 15-year period. These STCs can then be sold or traded to registered agents or buyers, who use them to meet their own renewable energy targets.

The Small-scale Renewable Energy Scheme (SRES) is a government initiative in Australia that provides financial incentives for the installation of small-scale renewable energy systems, including Solar photovoltaic (PV) systems.

Under the SRES, Solar PV systems with a capacity of 100 kilowatts or less are eligible to receive STCs. The number of STCs awarded to a system is determined by its geographical location, installation date, and the amount of renewable energy it is expected to generate over 15 years. This expected energy generation is calculated based on the system’s capacity, location, and the amount of sunlight it receives.

Once the Solar PV system is installed and accredited, the system owner can create STCs for the expected energy generation. These STCs can then be sold or traded to registered agents or buyers who have obligations to meet their own renewable energy targets, such as electricity retailers. The value of STCs can vary depending on market demand and supply.

The purpose of this scheme is to provide a financial incentive to encourage the installation of small-scale renewable energy systems and contribute to Australia’s overall renewable energy target. By creating a market for STCs, the SRES helps reduce the upfront cost of installing Solar PV systems, making them more accessible to individuals and businesses.
