Maryborough ranks 144th in Queensland for solar installations — in the middle tier of 449 postcodes tracked by the Clean Energy Regulator across the state. 133 new systems were installed in the past 12 months, a 19% increase on the previous year — steady growth consistent with continued community uptake.
The combined impact is substantial: Maryborough's solar community avoids an estimated 26,943 tonnes of CO₂ every year — equivalent to taking 12,830 cars off the road or powering around 5,389 average Australian homes with clean electricity. 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.
