What Is an 8.5kW Solar System?

An 8.5kW rooftop solar photovoltaic system converts sunlight into electricity to power your home. The setup typically includes around 18–22 solar panels, best suited for medium to large-sized homes with multiple occupants and higher energy usage.

8.5kW is slightly larger than the 6.6kW system (the most common size for residential use) and smaller than the 10kW system. This makes an 8.5kW solar system a great choice for homeowners who need more power than the typical 6.6kW residential system, but don’t need a massive 10kW setup.

How Much Energy Does It Produce Daily?

The number of solar panels needed has reduced over the last decade as the efficiency of solar panels has soared.

An 8.5kw solar system’s daily output averages around 32–36kWh/day on the Gold Coast. That’s enough electricity to power your home while reducing or even eliminating your utility bill.

How Much Does an 8.5kW Solar System Cost?

For systems installed in Queensland, an 8.5kw solar system costs $8,500 to $12,000 on average. However, this will vary depending on the installation company’s rates and the products used.

At Solahart Gold Coast, we use premium quality panels and inverters, comply with local regulations set by the local municipality or state, and provide warranties for all products sold. Battery storage options are also available at an additional cost.

With Battery Storage (Optional Upgrade)

Batteries store excess power for later use at nighttime or during a blackout. Excess power can also be sold back to the grid for extra money or utility bill credits.

The 8.5kw solar system with batteries cost ranges from $15,000 to over $20,000. Choose from premium battery options like the GoodWe Lynx Home F Series, Tesla Powerwall 3, and Enphase IQ Battery 5P to get the most out of your 8.5kW solar system.

How Much Will an 8.5kW Solar System Save Me?

The 8.5kw solar system price can be offset by the annual savings accrued after having the system installed. Estimates for savings in Queensland sit around $1,500 to $2,500+ per year on average. When contrasted with the initial installation and setup cost, the payback period ranges from 3.4 to 4.8 years. Savings increase when solar is used during the day or paired with solar batteries.

Is an 8.5kW Solar System Right for Your Home?

The 8.5kW solar system is the perfect middle ground for larger households and home businesses that allows you to choose a system that perfectly matches your household’s specific energy use without paying for a system that’s too big (i.e. 10kW) or getting one that’s too small (6.6kW).

If you’re still undecided, we’ll provide you with a free, no-obligation consultation to assess fit. Australia also offers rebates like Small-scale Technology Certificates (STCs) to help reduce the upfront cost of your new solar system.

"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"
