10,703 solar installations registered with the Clean Energy Regulator · ranked top 5% in Queensland · data current as at 2026-05-15
Based on last week's Queensland grid mix (avg 810 gCO₂/kWh), Petrie's 10,703 solar systems typically avoid around 66.32 tonnes of CO₂ every hour during peak generation.

Petrie is one of Queensland's strongest solar communities, ranking 19th in the state — ahead of 96% of all Queensland postcodes tracked by the Clean Energy Regulator. New installations eased in the past 12 months (490 systems, 18% below the previous year), a natural slowdown after earlier periods of stronger uptake.
The combined impact is substantial: Petrie's solar community avoids an estimated 105,942 tonnes of CO₂ every year — equivalent to taking 50,449 cars off the road or powering around 21,188 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.
