9,541 solar installations registered with the Clean Energy Regulator · ranked top 10% in Queensland · data current as at 2026-08-15
Based on last week's Queensland grid mix (avg 810 gCO₂/kWh), Rockhampton's 9,541 solar systems typically avoid around 59.12 tonnes of CO₂ every hour during peak generation.

Rockhampton is one of Queensland's strongest solar communities, ranking 27th in the state — ahead of 94% of all Queensland postcodes tracked by the Clean Energy Regulator. New installations eased in the past 12 months (531 systems, 13% below the previous year), a natural slowdown after earlier periods of stronger uptake.
The combined impact is substantial: Rockhampton's solar community avoids an estimated 94,440 tonnes of CO₂ every year — equivalent to taking 44,971 cars off the road or powering around 18,888 average Australian homes with clean electricity. This is estimated using Queensland's average grid emissions intensity of 810 gCO₂/kWh, sourced from OpenElectricity, applied to an average system size of 9kW.
