Darwin ranks 30th in Northern Territory out of 46 postcodes in the Clean Energy Regulator dataset, with 41 registered systems to date. New installations eased in the past 12 months (0 systems, 100% below the previous year), a natural slowdown after earlier periods of stronger uptake.
Darwin's solar systems avoid an estimated 321 tonnes of CO₂ per year, equivalent to 153 fewer cars on the road annually. This is estimated using Northern Territory's average grid emissions intensity of 640 gCO₂/kWh, sourced from OpenElectricity, applied to an average system size of 9kW.
