2,243 solar installations registered with the Clean Energy Regulator · ranked top 25% in South Australia · data current as at 2026-04-03
Based on last week's South Australia grid mix (avg 370 gCO₂/kWh), Semaphore's 2,243 solar systems typically avoid around 6.35 tonnes of CO₂ every hour during peak generation.

Semaphore sits in the top third of South Australia for solar uptake, ranking 76th in the state out of 347 postcodes in the Clean Energy Regulator dataset. 120 new systems were added in the past 12 months, with growth of 2% on the previous year — typical of a maturing market where most interested households have already installed.
The combined impact is substantial: Semaphore's solar community avoids an estimated 10,142 tonnes of CO₂ every year — equivalent to taking 4,830 cars off the road or powering around 2,028 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.
