Kalgoorlie ranks 244th in Western Australia out of 388 postcodes in the Clean Energy Regulator dataset, with 86 registered systems to date. New installations eased in the past 12 months (5 systems, 17% below the previous year), a natural slowdown after earlier periods of stronger uptake.
Kalgoorlie's solar systems avoid an estimated 662 tonnes of CO₂ per year, equivalent to 315 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.
