Prahran ranks 279th in Victoria for solar installations — in the middle tier of 713 postcodes tracked by the Clean Energy Regulator across the state. Growth has been strong, with 75 new systems installed in the past 12 months — a 34% increase on the previous year, making Prahran one of Victoria's faster-growing solar postcodes.
Collectively, Prahran's 817 solar systems avoid an estimated 9,784 tonnes of CO₂ per year — the equivalent of removing 4,659 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.
