13.2kW Solar System
From $6,890 fully installed.
30 Tier-1 panels · 10kW 3-phase inverter · ~53 kWh/day in Brisbane. The largest residential system before commercial pricing kicks in — save $4,600+ a year.
For homes that don't compromise.
When 10.5kW isn't enough — and commercial is overkill.
Luxury & executive homes
5+ bedrooms, 60+ kWh/day with home theatre, sauna or wine room.
Dual EV households
Charge two EVs from sunlight — 100 km of range per hour combined.
Home offices & studios
Run servers, 3D printers, podcast rigs — zero added power cost.
Battery-first households
Generate enough to fully charge a 13-20 kWh battery every day.
A $6,800 bill becomes $1,600.
Luxury homes regularly run $6,000-$9,000/yr on power. A 13.2kW system flattens that to a small night-time bill — and with battery storage, you can hit zero in months you don't run the pool heater.
