FAQ

6.65kW Solar & Battery System Questions

A 6.65kW system uses 16 solar panels at 415W each. Panels are typically installed across one or two roof faces, depending on your roof size and orientation.
A 6.65kW 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.
The 6.65kW package includes a 6kW hybrid inverter (Sungrow, GoodWe, or Fronius) and a 16kWh battery, depending on availability and your roof configuration.
The 16kWh battery is included in the $7,499 package price — it is not a separate add-on. The Cheaper Home Batteries Program rebate may also apply, reducing your cost further if you are eligible.
For most 3-bedroom Sydney homes using 20–25 kWh per day, a 6.65kW system with a 16kWh battery will offset a large majority of electricity costs, including much of your evening usage from stored solar energy. If your usage is significantly above average, a 10.45kW or 13.3kW system may suit better.
