Blackwood is one of South Australia's strongest solar communities, ranking 22nd in the state — ahead of 94% of all South Australia postcodes tracked by the Clean Energy Regulator. 266 new systems were installed in the past 12 months, a 17% increase on the previous year — steady growth consistent with continued community uptake.
The combined impact is substantial: Blackwood's solar community avoids an estimated 18,742 tonnes of CO₂ every year — equivalent to taking 8,925 cars off the road or powering around 3,748 average Australian homes with clean electricity. This is estimated using South Australia's average grid emissions intensity of 370 gCO₂/kWh, sourced from OpenElectricity, applied to an average system size of 9kW.
