6.kW and 6.6kW solar systems are becoming increasingly popular with medium to large family Australian households as they are a cost-effective and reliable energy solution. A 6kW system will consist of a configuration of about 22-24 solar panels and utilise between 275W to 320W modules with a 5kW inverter.

The purchase and installation cost of 6kW or 6.6kW solar system could range between $5,500 – $7,500, which includes about 22-24 panels and an inverter. The price will fluctuate depending on the quality of inverter and solar panels and increase further if a solar battery is included in the purchase.

Depending on factors such as roof angle, location (coastal or inland), system positioning, and quality of solar panels and inverter, a 6kW solar system is capable of generating 26.4 units per day. An inverter plays a crucial role in a solar power system as it is the gateway between the panels and your homes electrical infrastructure. Therefore, a quality inverter such as a Fronius is essential in generating better results.
