6.6kW vs 10kW Solar Systems – Which One Should You Choose?
If you’re exploring solar options for your home in Wollongong, Shellharbour, or Kiama, you’ve likely come across two of the most popular sizes: 6.6kW and 10kW solar systems. So, how do you choose the right one?
| Feature | 6.6kW System | 10kW System |
|---|---|---|
| Daily Output (avg) | 24–27 kWh | 38–44 kWh |
| No. of Panels | 16–18 | 24–28 |

| Best for | Average homes | Larger homes, home businesses |
| Cost Range | $5,000–$8,000 | $9,000–$13,000 |
The 6.6kW solar system is ideal for medium-sized households, offering great value and high efficiency. Meanwhile, a 10kW system suits homes with higher energy needs—such as larger families or properties with pools, electric vehicles, or home offices.
🏠 When a 10kW System Makes More Sense
- Your energy bills are consistently over $500/month
- You work from home and run multiple appliances during the day
- You want to future-proof your system with EV charging or battery expansion
🌞 Why 6.6kW Is Perfect for Most Illawarra Families
Most families in Wollongong, Kiama, and Shellharbour benefit from the balance of affordability and output that a 6.6kW system provides. It’s the sweet spot—eligible for maximum government rebates and usually sufficient to cover 70–90% of your power usage, especially with a battery or smart monitoring.

- Meets eligibility for full government solar rebates
