FAQ

6.6kW Solar System Questions

A 6.6kW system uses 16–18 solar panels, depending on panel wattage. At 370W per panel, you need 18 panels. At 415W, you need 16 panels. Panels are typically installed across one or two roof faces, depending on your roof size and orientation.
A 6.6kW system requires approximately 36–40 square metres of unshaded roof space. Our team assesses your roof during the free site inspection to determine the best layout, orientation, and mounting configuration.
We use Sungrow, GoodWe, or Fronius inverters in the 6.6kW package, depending on availability and your roof configuration. All options are hybrid-ready, meaning a battery can be added without replacing the inverter.
Yes. Every 6.6kW system we install is pre-wired and inverter-compatible for battery addition. The NSW battery rebate is also available to existing solar owners — up to $1,600 off your battery when you are ready to upgrade.
For most 3-bedroom Sydney homes using 20–25 kWh per day, a 6.6kW system will offset 60–80% of electricity costs depending on how much usage occurs during daylight hours. If your usage is significantly above average, a 10kW or 13.2kW system may suit better.
