Pakenham ranks 489th in Victoria out of 713 postcodes in the Clean Energy Regulator dataset, with 178 registered systems to date. New installations eased in the past 12 months (7 systems, 30% below the previous year), a natural slowdown after earlier periods of stronger uptake.
Collectively, Pakenham's 178 solar systems avoid an estimated 2,132 tonnes of CO₂ per year — the equivalent of removing 1,015 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.
