Darwin sits in the top third of Northern Territory for solar uptake, ranking 10th in the state out of 46 postcodes in the Clean Energy Regulator dataset. Growth has been strong, with 42 new systems installed in the past 12 months — a 45% increase on the previous year, making Darwin one of Northern Territory's faster-growing solar postcodes.
Collectively, Darwin's 666 solar systems avoid an estimated 5,209 tonnes of CO₂ per year — the equivalent of removing 2,480 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.
