QLD STC Rebate Calculator: Solar & Battery Incentives

How STCs Work in Queensland

Brisbane and South East Queensland are primarily Zone 3 (factor 1.382), Central Queensland is Zone 2 (factor 1.536), and Far North Queensland including Cairns is Zone 1 (factor 1.622). The number of STCs you receive depends on your specific postcode's zone factor, your system size, and the installation year. STCs are claimed by your installer and the rebate is deducted directly from your system price upfront.

Queensland has the widest zone variation in Australia, with tropical northern areas receiving the highest STC values.
