Mackay ranks 263rd in Queensland for solar installations — in the middle tier of 449 postcodes tracked by the Clean Energy Regulator across the state. 50 new systems were installed in the past 12 months, a 11% increase on the previous year — steady growth consistent with continued community uptake.
Collectively, Mackay's 581 solar systems avoid an estimated 5,751 tonnes of CO₂ per year — the equivalent of removing 2,739 cars from the road. This is estimated using Queensland's average grid emissions intensity of 810 gCO₂/kWh, sourced from OpenElectricity, applied to an average system size of 9kW.
