Gungahlin ranks 22nd in Australian Capital Territory out of 28 postcodes in the Clean Energy Regulator dataset, with 338 registered systems to date. New installations eased in the past 12 months (14 systems, 26% below the previous year), a natural slowdown after earlier periods of stronger uptake.
Collectively, Gungahlin's 338 solar systems avoid an estimated 3,263 tonnes of CO₂ per year — the equivalent of removing 1,554 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.
