What is a 6.6kW Solar System?

A 6.6kW solar system converts sunlight into electricity via solar panels to power your home and reduce reliance on the grid. They typically require 15–20 solar panels, each producing 415–440W of power.

Due to its smaller size, the 6.6kW system is compatible with most residential rooftops. In South East Queensland, expect a daily energy output range of ~24–27kWh/day. Local weather conditions also influence a system’s daily output.

How Many Panels Are in a 6.6kW System?

Today, a 6.6kW solar system using 370 to 440-watt (W) modules will have about 15-20 solar panels. This number has reduced tremendously over the last decade. Now, even fewer panels may be needed due to improvements in panel efficiency.

How Much Does a 6.6kW Solar System Cost?

The average 6.6kW solar system price in Australia typically ranges from $5,500 to $9,000. This price may vary depending on a combination of product quality, type of inverter used, and labour.

At Solahart, we only use premium panels and inverters. We also offer all customers free assessments and installation support from our trusted team of local installation experts.

With Battery Storage (Optional Add-on)

Battery storage is an optional add-on that is well worth the investment. Without a battery storage system, the energy generated from the solar panels is used in the home before surplus energy is sent back to the grid. A battery can store surplus energy and use it in the evening to power the home, rely less on the grid, support blackout protection, and save money on electricity bills.

The 6.6kW solar system with battery price can range from $12,000 to $16,000+.

How Much Will a 6.6kW Solar System Save Me?

The initial cost of a new solar system will soon be paid back by the annual savings alone. The payback period ranges from 2.8 to 4.4 years. Estimates for annual savings in Queensland sit around $1,128 to $1,800, depending on usage and feed-in tariffs. Savings are increased when solar is used during the day or paired with solar batteries.

Is a 6.6kW Solar System Right for You?

If you’re considering switching to solar energy, chances are that you’re already feeling the effects of Australia’s rising energy prices. A 6.6kW solar system addresses this issue head-on. This solar system size is perfect for medium-sized households of 3–4 people that have average or near-average daytime usage.

Australia offers financial incentives like Small-scale Technology Certificates (STCs) to help reduce the upfront cost of a 6.6kW system. Discuss your usage patterns and available roof space with Solahart today to confirm suitability.

"Hi John, Solahart: Technicians were on time, installation was completed efficiently with no fuss or bother. Personnel who installed panels and inverter were very pleasant and nice to know. They gave us full instructions on the operation and what happens after that. The bloke from origin came today and connected our new meter, so once the rain stops we will know how effective it is. Thank you for your follow up Regards Ian & Carol"
