Surrey Hills sits in the top third of Victoria for solar uptake, ranking 166th in the state out of 713 postcodes in the Clean Energy Regulator dataset. Growth has been strong, with 152 new systems installed in the past 12 months — a 24% increase on the previous year, making Surrey Hills one of Victoria's faster-growing solar postcodes.
The combined impact is substantial: Surrey Hills's solar community avoids an estimated 20,227 tonnes of CO₂ every year — equivalent to taking 9,632 cars off the road or powering around 4,045 average Australian homes with clean electricity. 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.
