Margaret River ranks 214th in Western Australia for solar installations — in the middle tier of 388 postcodes tracked by the Clean Energy Regulator across the state. 10 new systems were added in the past 12 months, with growth of 0% on the previous year — typical of a maturing market where most interested households have already installed.
Collectively, Margaret River's 145 solar systems avoid an estimated 1,116 tonnes of CO₂ per year — the equivalent of removing 531 cars from the road. 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.
