10,927 solar installations registered with the Clean Energy Regulator · ranked top 5% in Queensland · data current as at 2026-08-15
Based on last week's Queensland grid mix (avg 810 gCO₂/kWh), Petrie's 10,927 solar systems typically avoid around 67.71 tonnes of CO₂ every hour during peak generation.

Petrie is one of Queensland's strongest solar communities, ranking 20th in the state — ahead of 96% of all Queensland postcodes tracked by the Clean Energy Regulator. 549 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: Petrie's solar community avoids an estimated 108,159 tonnes of CO₂ every year — equivalent to taking 51,504 cars off the road or powering around 21,632 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.
