For a typical New Zealand home using around 8,000 kWh per year, you might need between 10 to 20 solar panels to cover your electricity needs.. For a typical New Zealand home using around 8,000 kWh per year, you might need between 10 to 20 solar panels to cover your electricity needs.. The average New Zealand home will need 15 to 20 solar panels, but the number really depends on:Your household energy needsHow much of your roof is available for panelsThe quality of the panelsThe kW capacity of your solar panel system.. Solar panel system sizes suitable for New Zealand homes normally range between 3 kW (9 solar panels) and 8kW (20 solar panels).. 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 15-20 solar panels to power their home. [pdf]
The larger 8kW, which is roughly 20 solar panels, is more suitable for a power-hungry home - with 5 bedrooms, a spa pool, battery storage, EV charger, etc. However, the statement above is very generalised, and a one-size-fits-all approach usually doesn’t work well when it comes to solar power.

A household can easily have a self-consumption rate of 60%, i.e using up 60% of the solar power generated. But there will need to be a few adjustments around the home, like timing the use of the washing machine and dishwasher sometime around the middle of the day.
Solar panels are better suited to some situations than others and assessing your property for its suitability is a great place to start. If you use power during the day, have electric hot water, and your roof is in good condition and is north facing, then your home is probably a good candidate for solar power.
