Who should consider 10kW
Homes with high monthly units, multiple air conditioners, or larger daytime loads may need a 10kW system. Exact fit depends on bill history, roof space, and usage pattern.
Why payback varies
Payback depends on import tariff, export credit, self-consumption, roof loss, fixed charges, and package cost. Hybrid systems usually cost more and pay back slower.
What to confirm with installers
For 10kW quotes, confirm inverter capacity, protection devices, net-metering scope, mounting structure, cable sizing, earthing, and after-sales support.
