Granville sits in the top third of New South Wales for solar uptake, ranking 190th in the state out of 721 postcodes in the Clean Energy Regulator dataset. 196 new systems were added in the past 12 months, with growth of 4% on the previous year — typical of a maturing market where most interested households have already installed.
The combined impact is substantial: Granville's solar community avoids an estimated 18,565 tonnes of CO₂ every year — equivalent to taking 8,840 cars off the road or powering around 3,713 average Australian homes with clean electricity. This is estimated using New South Wales's average grid emissions intensity of 790 gCO₂/kWh, sourced from OpenElectricity, applied to an average system size of 9kW.
