4kW solar power systems have been a popular choice for medium sized families over the years, however they are becoming less widespread as 5kW systems have become more affordable.

For the average sized Australian family, a 4kW system is a good option as it’s capable of covering average power consumption, helping to reduce power expenses. It can also increase the value of your home and help decrease carbon emissions.

When investing in solar it is important you do your research first. You need to make sure that the system you choose matches your particular situation. If it’s the wrong size you may find it doesn’t cover your power usage as well as you had hoped.
