Why 6.6kW Solar system is More Popular In Australia?

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, 5 kW 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. We provide more information below to help you understand if a 6.6 kW solar system is suitable for your needs.

6.6 kW solar system, 5 kW inverter, and 10 kWh battery combination

A 6.6 kW solar system is the best fit for medium or large families. With plenty of brands in the Australian market offering the best solar packages, look for panels that offer high efficiency and a 25-year warranty. An average household consumes around 20 kW/h per day. A 6 kW solar system produces from 17 to 27 kW/h of electricity. Thus, you can potentially increase your savings.

Inverter size is measured in kilowatts (kW). The maximum output of the inverter must be equal to or greater than 75% of the solar panel array maximum output. Therefore, a 5 kW inverter is an ideal choice as it allows ‘oversizing’ by 133% to match the 6.6 kW solar power system. A 6.6 kW solar system, 5 kW inverter, and 10 kWh battery combination have become popular due to the following reasons.

  • Advanced lithium-ion battery
  • Offers greater capacity
  • Fast charging
  • Never-ending discharge power
  • Keep your solar system functioning during a power outage
  • Use the stored energy to power your home

How much energy will a 6.6 kW solar system produce in Australia 

About 26.4 kWh.

Ideally, 1kW of solar panels = 4kWh of electricity produced per day. Therefore, each kW of solar panels can generate electricity of about 4kWh per day. So, a 6.6kW solar system will generate about 26.4kWh on a good sunshine day. You can enjoy ample solar power.

A 6.6 kW solar system is made up of anywhere between 17 to 24 solar panels. The number of panels on your 6.6 kW solar varies based on how efficient the panels are. For instance, if you choose 20x330W panels or 24x275W panels, the result is a 6600 kW (6.6kW) system and both are highly efficient. 370W and 450W panels are also available in the Australian market, so you can reduce the number of panels on your roof.

With 6.6kW solar panels, almost all your energy needs are covered. Production varies depending on where you live. The table below shows the average system output from 6.6 kW rooftop solar package –

Is a 6 kW solar power system is enough for your needs?

The 6 and 6.6 kW are the best solar packages offered by many manufacturers in Australia. Though 5 kW was the preferred option, 6 kW is a good size for most homes. It is a wise choice for medium to large families. The real benefit of this rooftop solar package is when you take full advantage of a larger system. Like, adding a battery and inverters to store a huge amount of generated power and always remain off-grid.

To maximize the amount of sunlight that falls on panels, expert installers consider factors like roof space and orientation.

The availability of roof space might reduce because of heavily shaded sections or unusual pitch. An installer will work out the best orientation for your panels to produce more energy to meet your needs. Don’t be despair if your available roof space is less. Installers can make it happen to produce about 80% of their rated power.
