Caloundra is one of Queensland's strongest solar communities, ranking 3rd in the state — ahead of 99% of all Queensland postcodes tracked by the Clean Energy Regulator. Growth has been strong, with 1,568 new systems installed in the past 12 months — a 25% increase on the previous year, making Caloundra one of Queensland's faster-growing solar postcodes.
The combined impact is substantial: Caloundra's solar community avoids an estimated 196,255 tonnes of CO₂ every year — equivalent to taking 93,455 cars off the road or powering around 39,251 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.
