Postcode 3991 ranks 531st in Victoria out of 713 postcodes in the Clean Energy Regulator dataset, with 136 registered systems to date. New installations eased in the past 12 months (3 systems, 75% below the previous year), a natural slowdown after earlier periods of stronger uptake.
Collectively, Postcode 3991's 136 solar systems avoid an estimated 1,629 tonnes of CO₂ per year — the equivalent of removing 776 cars from the road. This is estimated using Victoria's average grid emissions intensity of 980 gCO₂/kWh, sourced from OpenElectricity, applied to an average system size of 9kW.
