6kW solar system: common questions
How much does a 6kW solar system cost?
The live prices for our 6kW packages are on this page. Each includes panels, a roughly 10kWh battery, installation and the CoC.
What is the off-grid 6kW option for?
The Felicity off-grid kit is for properties that want to run without a grid connection, or where grid power is unreliable. Most suburban homes choose a hybrid system instead.
How long will a 6kW system run my house at night?
That depends on what is switched on. As a rough guide, a 10kWh battery running about 1kW of essentials lasts most of a night.
Is 6kW worth it over 5kW?
Mainly for the bigger battery. If outages are long where you live, the extra storage makes the biggest difference.
