Rouse Hill is one of New South Wales's strongest solar communities, ranking 2nd in the state — ahead of 99% of all New South Wales postcodes tracked by the Clean Energy Regulator. Growth has been strong, with 1,345 new systems installed in the past 12 months — a 27% increase on the previous year, making Rouse Hill one of New South Wales's faster-growing solar postcodes.
The combined impact is substantial: Rouse Hill's solar community avoids an estimated 142,290 tonnes of CO₂ every year — equivalent to taking 67,757 cars off the road or powering around 28,458 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.
