What Is the Average Number of 6KW Solar Panel Systems Are Needed for Installation?

Each measuring 1m by 1.6m, solar panels will be required for a 6kw system on average.

However, the size and number of panels vary from maker to maker. Some manufacturers can produce solar panels with higher outputs and require fewer panels for the same output rating. To determine which solar panel option is ideal for you, choose the one that best fits your north-facing roof area.

According to the above predictions, you’ll need at least 40 meters squared +- 5 of roof space to install the solar kit.

How Do I Find Out If The 6kwh Solar Panel System Is the Right Size for Me?

When it comes to solar panel systems, the goal is for the typical Australian to save 90% or more on their power bills. If you use an average of 26 kWh each day, a typical single-phase 6kw system should suffice. You’ll need to calculate your power consumption over the last year.

Some of the things to consider if a 6kw solar panel system is appropriate for you are:

Your home’s energy usage

Some individuals choose to use as much renewable energy as they can afford to decrease their power bills and help the environmental movement. If you fall into this category and require low to moderate daily power consumption, a 6Kw solar system or greater may be ideal for you. Keep in mind that the greater you go, the more money you save through the Australian STC solar rebate system.

If you consume less than 26 kWh of power each day, a 6 kW system is ideal. The following is a list of typical appliances and other electrical equipment powered by a 6 kW system. Remember that these are only approximations, and solar output may vary according to local weather conditions. 

When choosing a 6kW solar panel system, there are several things to keep in mind. 


Can you afford a 6kW system? Is it affordable if you can afford one? Based on your daily usage, does it make sense to you? If you can interpret the figures without considering the feed-in tariffs, you’re ready to go. As previously said, a solar system with an output that you can utilize is more appealing when it comes to payback periods. 


If you reside in a place with a lot of year-round sunshine, a bigger wattage solar system may make sense. The lovely weather will not only make the solar system more affordable, but it will also result in greater profits from your solar system.

If you use 22 kWh of electricity per day in Brisbane, for example, you’ll feed 17 kWh to the grid and receive 8c per kilowatt-hour under the feed-in tariffs. 70% of household power is consumed at night, but all solar energy is created during the day. 

Roof space

This must be the first thing you look for. For this to work, you’ll need adequate North-facing roof space. In some situations, you may get away with it facing on somewhat varying angles, but you’ll need to consult with a solar expert first before doing so. 

How Much Electricity Will a 6kWh Solar Panel System Generate?

Solar energy systems tend to have distinct output levels, which are dependent on the site. A 6kwh solar system should generate at least 25Kwh under ideal conditions. However, using climate data from the Australian Bureau of Meteorology’s datasheets and solar vendor information, 6Kwh solar outputs can be best estimated by region as shown below:

City/ Location Estimated 6Kw solar daily energy output
Canberra and surrounding areas 25.24Kwh
Adelaide and surrounding areas 25.66Kwh
Brisbane and surrounding areas 27.36Kwh
Melbourne and surrounding areas 21.95Kwh
Perth and surrounding areas 29.1Kwh
Sydney and surrounding areas 25.6Kwh
Hobart 19.1Kwh

The various figures based on location are primarily connected with variations in solar radiation levels throughout the day. Other elements, however, influence individual solar outputs, including: 

Panel orientation and tilt – The amount of power generated by a solar panel system is determined by the orientation and tilt of the panels. As a result, it’s critical to have an adequate area on the right side of your roof for the panels.

Different locations may need different tilt and orientation requirements for solar panels depending on solar radiation data. However, you shouldn’t be concerned about these particular criteria. The solar firm will most likely complete its study and deploy the solar panels in the best yield-boosting location. 

Solar system quality – In terms of quality and efficiency, solar panel systems from different manufacturers aren’t comparable. For example, a high-quality smart energy solar kit would yield greater than a lower quality standard kit. Most solar power installations have an output tolerance of two units or less than their watt rating. 

Inverter setup and efficiency – The inverter may sometimes modify the amount of energy you get from a solar system. If you do not have a large solar system yet, your installer may recommend obtaining a lower-wattage inverter to overclock the system and optimize solar performance. 

Shading – The amount of power you can generate with your daily solar output may be restricted by trees and large structures that block direct sunshine from reaching your property. To get the most out of your solar system, speak to the solar installer about any shading concerns and how you can minimize them. 

Panel Maintenance –Dust, dirt, and other foreign objects will accumulate over time on your solar power system. Solar panels require relatively little maintenance. When it comes to solar systems, the most important factor is not the rating or radiation levels; rather, it’s the panel’s maintenance. 

Note: Dirt and debris can reduce the output by a low percentage, while physical damage such as fractures will have a huge influence. 

Ambient temperature – Solar power system performance is reduced by high temperatures. You may get diverse solar outputs when temperatures reach certain levels depending on the installation method and panel temperature coefficients. Because heat-affected zones are prone to shifting, it’s critical to examine current temperatures in your location and seek assistance from the installer on the best installation approach for optimum performance.

Loss – There will be no significant loss in DC or AC cabling, which will have a little effect on your terminal solar output. The accuracy of transmission over a distance is determined by many factors, including cabling length, noise, and quality. 

Do I Need A 6Kw Or A 6.6kW Solar Panel System?

Many consumers struggle to decide between the extremely popular 6kWh and a 6.6kW solar panel. Given the variety of options and alternatives, putting a solar system in your home may undoubtedly be one of the most exciting projects you’ve ever embarked on. However, there are some things to consider before making such a major purchase:

Even when the 6kW solar system kit adds an extra 0.600Kwh to the mix, there is little price difference in the overall bill. This holds even if you include a 6.6-kW solar power system kit with an energy storage system. 

More STCs – For reasons best known to the regulators, going for the slightly bigger 6kWh system will give you more STCs (quite a margin between them). A customer who purchases a 6kW solar system in Western Shore, Tasmania, will receive 86 STCs. In contrast, a 6Kwh system would give the same person 78 STCs.

Again, there isn’t much difference in panel count between a 6kWh solar kit and a 6Kwh Kit. Some firms will sell both systems but with varying rated outputs.

However, if you want to reduce your power bill and pay it off faster, a 6Kwh system may make sense for various reasons, such as energy consumption and payback period. The 6Kwh solar system has a somewhat shorter payback period than its similar counterpart. However, remember that payback periods are influenced by your energy use statistics, such as the solar-to-grid ratio. 

Will I Need an Inverter?

To convert DC from the solar panels to usable AC, an inverter is required for every solar power system. The good news is that a 5Kw inverter would be enough for a 6kW solar system. This implies that the price will be lower since you won’t invest in a bigger inverter. This is because a 5kw inverter can safely be “over-clocked” to handle 6kw solar system power demands. 

Why not a 6kW inverter?

In a nutshell, it is less expensive. A 6-kilowatt inverter is 30 per cent more expensive than a 5-kilowatt inverter. The ability to do the task easily with a 5-kW inverter saves you money in the long run. It’s cheap, so there’s no losing side. 


If you are considering a solar system, it is important to understand the details of your home and how much power you use. A 6KW solar system is great for homes with an average energy usage or those upgraded from 4KW systems in recent years. This sized solar panel works well for most houses, but if your house uses over 12 kWh per day on average, this size might not be effective.
