Small-scale Technology Certificates (STCs): This is the main rebate program for residential and small-scale commercial solar installations. STCs are created for every megawatt-hour of electricity that a solar system is expected to generate over its lifetime. These certificates can be sold to electricity retailers, who are required by law to purchase a certain number of them each year.

The value of STCs fluctuates based on supply and demand in the market, but they can significantly reduce the upfront cost of installing a Solar system. STCs are typically assigned to the installer, who will factor the value of the certificates into the overall cost of the installation.

To be eligible for STCs, the Solar system must be installed by a Clean Energy Council-accredited installer and meet certain quality and safety standards. The number of STCs that can be claimed for a system depends on its size, location, and the amount of sunlight it will receive.

Overall, STCs are an important incentive to encourage the uptake of Solar power in Australia, helping to reduce greenhouse gas emissions and move towards a more sustainable energy future.
