Thornbury 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. 108 new systems were installed in the past 12 months, a 9% increase on the previous year — steady growth consistent with continued community uptake.
The combined impact is substantial: Thornbury's solar community avoids an estimated 19,748 tonnes of CO₂ every year — equivalent to taking 9,404 cars off the road or powering around 3,950 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.
