Langwarrin ranks 471st in Victoria out of 713 postcodes in the Clean Energy Regulator dataset, with 202 registered systems to date. 9 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, Langwarrin's 202 solar systems avoid an estimated 2,419 tonnes of CO₂ per year — the equivalent of removing 1,152 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.
