Under the Renewable Energy Target, every megawatt hour of qualifying energy generation is eligible for renewable energy certificates (RECs).
These certificates come in two types: large and small. Small-scale technology certificates (STCs) are the ones that apply to residential solar installations.
The Small-scale Renewable Energy Scheme creates a financial incentive for individuals and small businesses to install eligible small-scale renewable energy systems such as solar panel systems, solar water heaters and heat pumps.
Under this program, if you have installed an eligible small-scale renewable energy system within the past 12 months you may be eligible to create small-scale technology certificates.
