As we know, five kW is in demand in Australia and other areas because of the combination of high energy yield and a great return on investment in future. But what is the price, output and exact roi as per area in Australia? So here are all the details.
The 5kW solar system consists of 15-20 panels and about 25-35 m2 of roof space, depending upon the wattage of panels and how they tilt. Solar Panel sizes vary by brand, and panels are sized for residential or commercial properties.
According to Australia Demand and Esteem Energy, the average cost of a 5kw solar system is around $3000 inc GST and STC rebate.
Here are some breakdowns of charges according to states:
And it can vary according to the area, property size, roof type and other factors. For more info, you can go to:

- These are average prices, complex installation on concrete or tile roofs will be more expensive
- The quality of the solar system product that customers have selected will also influence the price
History behind 5 kw :
How much Power will it generate?:
Depending on various factors, the actual Power will vary, and factors included are System geographical location, daily/annual solar irradiation and level that cloud covers
- Orientation and tilt angle of the solar panel layout
- Shade cast on solar panels
- Actual operating temperature of the panels
- The performance of the individual components
As we can see in 1 point, different areas receive different amounts of sunlight. The amount of sunshine falling on solar panels directly impacts the system’s output. For example, in Australia, rooftops can expect an average of around 4.5 hours of peak sun per day. This number may range up to 5.8 PSH per day.
The financial return on the 5kw system:
The financial return is a bit harder to work out and mainly changes whether the solar system Feed Tariff (FIT) is available to the owner of the system, which pays them some small amount of money for each unit of solar power that they export to the electricity grid.
We can assume the indicative payback period, annual internal rate of return(IRR), and one year of annual savings using a 5 kW solar system for regular everyday usage situations in some major cities of Australia.Usually, payback time depends heavily on the amount of solar energy consumed directly by export to the grid.
NOTE:
- An average of 25 kwh/day was taken as an assumption by household consumers
- Energy rates and FIT have been used towards the market’s demand and end.
