Toowoomba is one of Queensland's strongest solar communities, ranking 29th in the state — ahead of 94% of all Queensland postcodes tracked by the Clean Energy Regulator. 626 new systems were added in the past 12 months, with growth of 4% on the previous year — typical of a maturing market where most interested households have already installed.
The combined impact is substantial: Toowoomba's solar community avoids an estimated 92,164 tonnes of CO₂ every year — equivalent to taking 43,888 cars off the road or powering around 18,433 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.
