Why 6.6kW is most popular in McDowall: The 6.6kW system (with a 5kW inverter) represents the sweet spot for most households. It's the maximum size eligible for standard single-phase connection in Australia, offers excellent cost-per-watt value, fits on most residential roofs (requiring approximately 33-40m² of suitable north-facing or west-facing roof space), and typically generates 10,479 kWh annually in McDowall—enough to cover 70-100% of average household consumption.
