Mandurah is one of Western Australia's strongest solar communities, ranking 1st in the state — ahead of 99% of all Western Australia postcodes tracked by the Clean Energy Regulator. 1,071 new systems were installed in the past 12 months, a 8% increase on the previous year — steady growth consistent with continued community uptake.
The combined impact is substantial: Mandurah's solar community avoids an estimated 158,140 tonnes of CO₂ every year — equivalent to taking 75,305 cars off the road or powering around 31,628 average Australian homes with clean electricity. This is estimated using Western Australia's average grid emissions intensity of 630 gCO₂/kWh, sourced from OpenElectricity, applied to an average system size of 9kW.
