STC Zone 1, Australia's Highest Solar Rebate for Cairns
Cairns is located in STC Zone 1, Australia's highest STC rebate zone, reflecting the wet tropics' exceptional solar resource. A Cairns 6.6kW system attracts an STC rebate of approximately $3,800-$5,000 in 2026, significantly higher than Sydney or Melbourne. Wet season cloud cover (November-April) reduces generation in peak summer, but the outstanding dry season production more than compensates. Cyclone-rated mounting systems are required in Cairns.
