Darwin ranks 27th in Northern Territory for solar installations — in the middle tier of 46 postcodes tracked by the Clean Energy Regulator across the state. Growth has been strong, with 5 new systems installed in the past 12 months — a 67% increase on the previous year, making Darwin one of Northern Territory's faster-growing solar postcodes.
Darwin's solar systems avoid an estimated 399 tonnes of CO₂ per year, equivalent to 190 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.
