Brisbane is one of Australia's best cities for solar. Strong sun hours, STC Zone 1 (highest rebate values), and consistently warm weather drive excellent year-round generation. Queensland doesn't have a state solar rebate, but the federal STCs are more valuable here than in Victoria or Tasmania thanks to the Zone 1 rating.
💡 Local Tip
Brisbane's subtropical climate means solar panels produce well even in winter — expect only a 25–30% drop vs summer, compared to 40–50% in southern states.
