Horsham ranks 445th in Victoria out of 713 postcodes in the Clean Energy Regulator dataset, with 253 registered systems to date. 5 new systems were added in the past 12 months, with growth of 0% on the previous year — typical of a maturing market where most interested households have already installed.
Collectively, Horsham's 253 solar systems avoid an estimated 3,030 tonnes of CO₂ per year — the equivalent of removing 1,443 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.
