If we use a house in adelaide as an example you would need a 5kw solar system to generate this amount of power. To get these numbers we used high and low panel production ratios to calculate how many solar panels are needed on average. However if the household only consumes 40 of its electricity during daylight hours there is no point in installing such a large system.
