How much power does a 10kW Solar System produce?

Because with solar we want the daily output to cover most of your household’s energy usage for as long as possible across the day, which means we size up a solar system based on a system’s daily output, not the peak output. A solar system in Sydney will output around 4 times its size, so a 10kW system will output around 40kWh on an average day.
