6kW solar system
Perfect solution for smaller solar system power applications
Installations of 6kW (and 6.6 kW) solar power systems have become an increasingly common sight on rooftops around Australia in 2022, largely due to the ongoing plummeting cost of solar energy components, the remaining generous subsidy, and feed-in tariffs.
6kW or now more commonly seen 6.6 kW solar systems are becoming increasingly popular, thanks to several factors, including their affordability, ample size & ease of approval when it comes to connecting to the grid.
A 6kW solar system has 15-24 solar panels with a daily production of 18–25kWh, which is enough to power most homes. Installation costs range between $5,200 – $8,700, but this system will save you $950–$2,000 annually and features a 4 years payback period.
The 6kW solar power system is one of the most popular system sizes for most homeowners.
We’ll address that question in this in-depth review of the 6kW solar system by providing everything you need to know about its costs, functions, and savings potential.

1: Is A 6kW Solar Power System Suitable For My Home?
Depending on your location, the 6kW solar system produces 18kWh to 25kWh of electricity per day.
This solar output meets the needs of most average homes. If you’re an average family of two adults and up to two children which consumes around 20kWh of electricity per day, the 6kW or 6.6 kW solar power system is ideal. If you own a pool or ducted air conditioning, you may want to look for a larger system such as an 8kW or 10kW system. Or if you use less energy than the average household, a 3kW system may be more suited.
2: How Many Solar Panels Are In A 6kW System?
How many panels you need for a 6kW solar system depends on the output of your solar panels. However, it will be in the range of 15–24 panels.
Solar panels vary in power output. But the ones most often used in domestic applications have a power output of 250 W to 400 W. The size of a solar system is based on the number of panels used in the installation. For example, to achieve a 6kW solar system you can select one of the options in the table below:
Panel power | Number of panels needed |
250 | 24 |
300 | 20 |
350 | 17 |
400 | 15 |
FAQs: 6kw Solar Systems
The amount of roof space you need to install the 6kW system depends on the power output of your solar panel system. However, with the 250–400W residential solar panels, you’ll require 33.6–44.2m2. Using low-wattage solar panels necessitates more panels and roof space.
The price of a 6kW solar system varies widely. The cost of a 6kW system using quality components that are professionally installed will generally range between $5,200–$8,700 in early 2022. This price range takes into account the solar subsidy.
Some of the factors that affect how much you pay for a 6kW system include:
- Quality of products used. If you use good-quality components, the system will cost more.
- Solar installer charges. More challenging installation and high installer rates can increase your system prices.
- Solar incentives and rebate claims. Claiming more incentives reduces your overall cost.
The savings from a 6kW solar system in one year generally range between $850 and $1,800. The great news is that you can make lifetime savings worth $45,000 or more!
These savings come from energy bill savings and feed-in-tariff credits. Many variables go into calculating these savings:
1. Energy bill savings:
When you switch to solar, you’ll no longer be held hostage to high power bills. By generating and consuming your own power, your electricity bills will see a noticeable drop.
Your energy bill savings are the amount you would have paid for electricity but no longer pay due to solar. So, the higher your consumption and electricity rate, the more you’ll save on your electricity bills.
2. Feed-in tariff credits:
The feed-in tariff is the amount you receive for the surplus electricity you send to the grid.
By switching to solar, there will be times when your system produces more electricity than needed. If you don’t have batteries to store the surplus energy, it all goes to waste. The alternative is to send it to the grid for some credits.
Energy retailers offer different feed-in tariffs. The higher the feed-in tariff for your excess electricity, the more utility your solar power system delivers.
As a guideline, the payback period of a 6kW solar system is between 4 and 6 years. The payback period is the number of years it takes to break even or for the return on investment (ROI) to cover the installation cost. When you invest in a 6kW system, your returns from the investment represent the cost savings. Simply, the payback time is the duration of time it takes for the system’s savings to pay back the cost of installation.
Various factors can lower your solar system costs or shorten the payback time. These factors include:
- Installation cost. The more you pay for your system, the longer its payback time. Consider a 6kW system that saves you $1,200 annually; payback will be in 4.5 years if the system costs $5,400. But it will be 7 years if the system costs $8,000.
- Solar incentives/subsidies. If you are eligible for higher incentives, your solar installation price will be lower.
- Energy consumption. The more energy you consume daily, the more you’ll save if you switch to solar.
- Electricity rate. The higher your electricity rate, the more you’ll save via solar energy. This runs contrary to traditional electricity charges over the last decade, where rates have steadily increased.
- Feed-in tariff. You’ll profit more from your system if you receive higher FIT rates.
- Location. The sunnier your location, the more power your system will produce. You can increase your self-consumption with lower electricity bills and import more electricity to the grid for additional credits.
Depending on several 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 inverters)
Location is one of the main determinants of how much energy a solar system yields, as the amount of sunshine falling on a solar system’s solar panels directly affects the system’s output.
However, typical 6kW solar systems produce 18–25kWh of electricity per day. Or about 6–8.5 MW a year.
A 6kW solar system produces enough electricity to power most average homes.
The average household consumes about 20kWh of electricity per day. But the 6kW system produces between 18–25kWh of electricity (depending on your location). So 6kW system is a good choice.
The short answer to this question is yes. The production of a 6kW solar system significantly outstrips consumption when the panels are active, so adding battery storage is worthwhile.
QH Technology produced various specifications of batteries. 48V with 100Ah or 200Ah are most common. Here are their parameters:
Installing a battery storage system with a 6kW solar system will enable you to use more of the energy you produce. But whether you should install a battery depends on your budget, energy usage, and more.
If you plan to reduce your carbon footprint, save money or reduce your home electricity bills, installing a battery with a 6kW system is an excellent first step. But you should also consider the additional cost of battery installation, your payback period, and how much you are likely to save over time.
But wait, think a little bigger – think 6.6kW. Let me clarify–if your house is on a single-phase electricity supply, then you should get at least a 5kW inverter and 6.6kW of solar panels.
