A 6.6 kW solar system is a familiar Adelaide starting point, while larger homes, daytime businesses, EV owners and households moving away from gas may compare 10 kW or larger designs. The useful number is not panel count—it is how generation lines up with your actual consumption, export limit and future battery.
