Pakenham ranks 334th in Victoria for solar installations — in the middle tier of 713 postcodes tracked by the Clean Energy Regulator across the state. 31 new systems were added in the past 12 months, with growth of 7% on the previous year — typical of a maturing market where most interested households have already installed.
Collectively, Pakenham's 566 solar systems avoid an estimated 6,778 tonnes of CO₂ per year — the equivalent of removing 3,228 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.
