Norwood sits in the top third of South Australia for solar uptake, ranking 97th in the state out of 347 postcodes in the Clean Energy Regulator dataset. Growth has been strong, with 146 new systems installed in the past 12 months — a 35% increase on the previous year, making Norwood one of South Australia's faster-growing solar postcodes.
Collectively, Norwood's 1,954 solar systems avoid an estimated 8,835 tonnes of CO₂ per year — the equivalent of removing 4,207 cars from the road. This is estimated using South Australia's average grid emissions intensity of 370 gCO₂/kWh, sourced from OpenElectricity, applied to an average system size of 9kW.
