A 6.6kW solar system is one of the most popular choices for Australian households. It offers the perfect balance between affordability and performance.
Whether in a small urban home or a modest-sized family property, a 6.6kW system provides enough power to cover most daily electricity needs.
For optimal solar performance, you’ll need approximately 25–30m2 of north-facing roof space.
A 6.6kW system provides enough energy to power lighting, appliances, cooling, and more. Power bills can be reduced by 60–85% depending on usage habits and tariff structure.
Looking to maximize savings? Upgrade to a Battery-ready package to store solar power for night time use and blackout protection.
Most homeowners recover their solar investment in 2 to 4 years and enjoy 20+ years of free power afterwards.
A 6.6kW system can support future needs like EV charging or home office power use.
Solar output varies depending on your location, roof orientation, and climate. Here’s what you can expect to generate daily with a 6.6kW system in major Australian cities:
| City | Approx. Avg. Daily Output |
|---|---|
| Adelaide | 27.7 kWh |
| Brisbane | 27.7 kWh |
| Melbourne | 23.8 kWh |
| Perth | 29.0 kWh |
| Sydney | 25.7 kWh |
That’s enough to power everything from your lights and fridge to washing machines, air conditioners, and more while slashing your energy bills.

Trusted Solar
We recently had a solar system installed at our property, and we couldn't be happier with the entire experience. From the initial consultation to the final installation, the team was professional, knowledgeable, and incredibly helpful. They took the time to explain the system, answer all our questions, and made sure we understood how everything would work.....
