South Australia grid · community impact

Based on last week's South Australia grid mix (avg 370 gCO₂/kWh), Gawler's 4,013 solar systems typically avoid around 11.36 tonnes of CO₂ every hour during peak generation.

Grid intensity data: Open Electricity (openelectricity.org.au) · 7-day average · updates monthly

Gawler 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. New installations eased in the past 12 months (97 systems, 47% below the previous year), a natural slowdown after earlier periods of stronger uptake.

The combined impact is substantial: Gawler's solar community avoids an estimated 18,145 tonnes of CO₂ every year — equivalent to taking 8,640 cars off the road or powering around 3,629 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.
