Small-scale Technology Certificates, or STCs, are a tradable commodity attached to eligible installations of renewable energy systems (including solar panels, solar water heaters and heat pumps).

Under the Federal Government’s Small-scale Renewable Energy Scheme, when you install an eligible system, you may claim a set number of these STCs.

This number is based on the amount of electricity in megawatt hours (MWh):


The number of certificates you can claim may vary depending on your geographic location, what you’re installing, whether your installation is eligible for Solar Credits, and/or the size and capacity of the installed system. For example, a 1.5kW solar panel system in Melbourne might be eligible for a minimum 21 STCs, while a solar water heater in Hobart might be eligible for a minimum of 20 STCs.

You can calculate the number of STCs claimable by a system by using the calculators on the Clean Energy Regulator website:
