How Much Is A 6.6 kW Solar System In Australia
How Much Is A 6.6 kW Solar System In Australia: 6.6kw solar system price sydney
Solar panels can range in output, it’s very common to see solar panels today at around 300 watts per panel to 400 watts per panel. The size of a solar system is the cumulative total of panels. Using a 330w solar panel as an example you need 20 x 330w solar panels to achieve a 6.6kw solar system.
Why 6.6kw solar system is more popular in Australia: 6.6kw solar system price sydney
With various solar power systems sizes, a 6.6 kW solar system is the most common solar system installed by Australian homeowners. The 6.6kW solar system offers greater capacity and makes battery storage or battery backup systems more feasible. A few years ago, 3 kW, 5kW solar systems were popular. However, the cost of solar power systems keeps reducing, making the bigger system more affordable. With that being said, a 6.6 kW solar system is a great size for anyone thinking about adding a battery.

How much energy will a 6.6kw solar system produce? 6.6kw solar system price sydney
Depending on various factors, the actual power output of a 6kW solar power system will vary. These variables include:
- Location and local climate
- Orientation and tilt angle of the solar panel array
- Whether there is any shade cast on the panels
- The performance of the individual components (primarily the panels and inverter)
Location is one of the main determinants of solar system energy yields, as the amount of sunshine falling on a solar system’s solar panels directly affects the system’s output. The table below provides rough approximations for how much energy a 6kW solar system will produce.
| Energy output from a 6.6kW solar system | |
| Capital City | Approx Solar Energy Production* (per day) |
| Adelaide | 24-26 kWh |
| Brisbane | 25-27 kWh |
| Canberra | 24-27 kWh |
| Darwin | 28-30 kWh |
| Hobart | 19-22 kWh |
| Melbourne | 21-24 kWh |
| Perth | 26-28 kWh |
| Sydney | 22-25 kWh |

How much does a 6.6kw solar system cost?
The average 6.6kW solar system will cost around $2999 after the federal STC rebate has been deducted. The government rebates reduce each year so the deals you might score now won’t be available in a year or two. The price of solar systems do, however, vary widely across the Australian market. A more cost-competitive 6.6kW solar power system consisting of cheaper, low-end products will cost less, while premium solar brands will generally cost much more but will prove to perform more efficiently over a longer duration based on past performance. How long is the payback period on a 6.6kw solar system. Keep in mind that returns may be better for systems whose price points are lower, or if you achieve a higher level of solar self-consumption. But also be mindful that you’ll want to be selective about the products and companies that you consider some deals are too good to be true.
