Under the SRES, eligible solar panel systems are awarded a certain number of small-scale technology certificates (STCs), which can be traded or sold. The number of STCs depends on the size of the system and the location of the installation.

STCs are a form of financial incentive provided by the Australian government to promote the installation of Solar panel systems. These certificates represent the environmental benefits of generating renewable energy and are created under the Small-scale Renewable Energy Scheme (SRES).

The number of STCs awarded to a Solar panel system is determined based on its size and the location where it is installed. The size of the system is measured in kilowatts (kW) and is calculated based on the system’s capacity to generate electricity.

In general, larger Solar panel systems are eligible for more STCs as they have a higher capacity to generate renewable energy. The location of the installation also plays a role in determining the number of STCs, as it affects the amount of Solar radiation received and the system’s energy generation potential.

The exact calculation of STCs is determined by the Clean Energy Regulator, which is responsible for administering the SRES. The regulator provides an online calculator that can be used to estimate the number of STCs that a Solar panel system is eligible for based on its size and location.

Once awarded, STCs can be traded or sold to electricity retailers or other entities that have a legal obligation to surrender a certain number of certificates to meet their renewable energy targets. This creates a market for STCs, where their value can fluctuate based on supply and demand.

By providing financial incentives through STCs, the SRES aims to reduce the upfront cost of installing Solar panel systems and promote the adoption of renewable energy in Australia.
