Romsey ranks 410th 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 25 new systems installed in the past 12 months — a 47% increase on the previous year, making Romsey one of Victoria's faster-growing solar postcodes.
Collectively, Romsey's 337 solar systems avoid an estimated 4,036 tonnes of CO₂ per year — the equivalent of removing 1,922 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.
