Margaret River sits in the top third of Western Australia for solar uptake, ranking 82nd in the state out of 388 postcodes in the Clean Energy Regulator dataset. Growth has been strong, with 184 new systems installed in the past 12 months — a 56% increase on the previous year, making Margaret River one of Western Australia's faster-growing solar postcodes.
The combined impact is substantial: Margaret River's solar community avoids an estimated 16,067 tonnes of CO₂ every year — equivalent to taking 7,651 cars off the road or powering around 3,213 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.
