It comes down to the capacity of the System you choose to install and the quality of the Panels, but the average New Zealand household will need 10-15 Solar Panels to power their home. When we talk about Solar System capacity, we talk about the kW rating, which is the maximum amount of energy the System can generate at its peak output.
