What does 7 kW mean?

When we say 7kW solar system, we mean that your system can generate 7000 watts of electricity at any given time. It will produce 7 kilowatt-hours (kWh) of electricity if it runs at the maximum rate for an hour. It would take 5 hours to generate 35 kWh of electricity.

Unfortunately, that 7kW system does not produce 7kW all of the time in the real world. Clouds, haze, rain, dust, and darkness can reduce the actual electricity production of an installation

Let’s look at an example to understand how a 7kW installation can generate energy because installations in different places produce varying amounts of energy. We can see that a 7kW system in Sydney will create 10,237 kWh per year using PV Watts. A 7kW system will cover around 75% of the average Sydney home’s energy demand.

As previously stated, solar energy output and power usage vary by state. In some places, a 7kW installation is more than adequate to cover a home’s entire energy consumption. In actuality, the average size of a solar installation in Australia is 6.6kW, therefore a 7kW system is larger than most people’s

How many solar panels are in a 7kW solar system?

A 6.6 kW system typically consists of between 20 and 24 solar panels. For a 6.6 kW system, the number of panels required varies depending on the panel’s size and efficiency of the panels. If you use highly efficient 370 Watt panels, you will only need 18 of them, whereas LG NeON® H+ Black premium 405w solar panel will require 17 even you will get a 6.8 kW solar system instead of 6.6 kW.

How much area is required?

A 7kW home solar system required 19 to 14 panels, each panel approximately measures 1.7msqm – 2msqm. So the roof area required for the system will be about 33m2-28m2 or potentially more depending on how your roof is laid out and whether tilt frames are required, which need to be spaced out more than panels mounted flush on the roof.

Panel orientation

In NSW, it’s better to position your panels to the north if you have the option. If you install your solar panels to the north, that will give the maximized power production. Even whether your panels face east or west, your system is likely to be effective, especially if your household consumes a vast portion of its electricity during the morning and evening peak periods.
