Darwin ranks 19th in Northern Territory for solar installations — in the middle tier of 46 postcodes tracked by the Clean Energy Regulator across the state. 8 new systems were added in the past 12 months, with growth of 0% on the previous year — typical of a maturing market where most interested households have already installed.
Collectively, Darwin's 163 solar systems avoid an estimated 1,275 tonnes of CO₂ per year — the equivalent of removing 607 cars from the road. 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.
