4,010 solar installations registered with the Clean Energy Regulator · ranked top 10% in South Australia · data current as at 2026-04-03
Based on last week's South Australia grid mix (avg 370 gCO₂/kWh), Blackwood's 4,010 solar systems typically avoid around 11.35 tonnes of CO₂ every hour during peak generation.

Blackwood is one of South Australia's strongest solar communities, ranking 23rd in the state — ahead of 93% of all South Australia postcodes tracked by the Clean Energy Regulator. 231 new systems were added in the past 12 months, with growth of 3% on the previous year — typical of a maturing market where most interested households have already installed.
The combined impact is substantial: Blackwood's solar community avoids an estimated 18,131 tonnes of CO₂ every year — equivalent to taking 8,634 cars off the road or powering around 3,626 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.
