Alexandra Hills sits in the top third of Queensland for solar uptake, ranking 89th in the state out of 449 postcodes in the Clean Energy Regulator dataset. 204 new systems were installed in the past 12 months, a 9% increase on the previous year — steady growth consistent with continued community uptake.
The combined impact is substantial: Alexandra Hills's solar community avoids an estimated 44,592 tonnes of CO₂ every year — equivalent to taking 21,234 cars off the road or powering around 8,918 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.
