Postcode 6219 ranks 302nd in Western Australia out of 388 postcodes in the Clean Energy Regulator dataset, with 32 registered systems to date. Growth has been strong, with 8 new systems installed in the past 12 months — a 33% increase on the previous year, making Postcode 6219 one of Western Australia's faster-growing solar postcodes.
Postcode 6219's solar systems avoid an estimated 246 tonnes of CO₂ per year, equivalent to 117 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.
