Merredin ranks 286th in Western Australia out of 388 postcodes in the Clean Energy Regulator dataset, with 42 registered systems to date. 5 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.
Merredin's solar systems avoid an estimated 323 tonnes of CO₂ per year, equivalent to 154 fewer cars on the road annually. 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.
