Postcode 6623 ranks 223rd in Western Australia for solar installations — in the middle tier of 388 postcodes tracked by the Clean Energy Regulator across the state. New installations eased in the past 12 months (2 systems, 33% below the previous year), a natural slowdown after earlier periods of stronger uptake.
Postcode 6623's solar systems avoid an estimated 985 tonnes of CO₂ per year, equivalent to 469 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.
