Gungahlin ranks 22nd in Australian Capital Territory out of 28 postcodes in the Clean Energy Regulator dataset, with 344 registered systems to date. Growth has been strong, with 20 new systems installed in the past 12 months — a 25% increase on the previous year, making Gungahlin one of Australian Capital Territory's faster-growing solar postcodes.
Collectively, Gungahlin's 344 solar systems avoid an estimated 3,321 tonnes of CO₂ per year — the equivalent of removing 1,581 cars from the road. This is estimated using Australian Capital Territory's average grid emissions intensity of 790 gCO₂/kWh, sourced from OpenElectricity, applied to an average system size of 9kW.
