Retail buy-back rates for solar power exported to the grid range from 7 to 17 cents, plus 15% if the system owner is GST-registered. Cost-effectiveness of a residential solar power occurs when system owners aim to use more of their solar power than what they export, by means of timed appliances, turning on appliances when the sun is out, energy management systems and battery storage. Commercial buildings that use power during the day can get a high return on th. [pdf]
We're working with the sector on New Zealand's renewable energy and low‑emissions transition. We're responsible for the governance and regulation of New Zealand's electricity industry. Solar power can help you become more self-sufficient, reduce your carbon footprint and reduce your energy costs.
Solar power in New Zealand is increasing in capacity, despite no government subsidies or interventions being available. As of the end of April 2024, New Zealand has 420 MW of grid-connected photovoltaic (PV) solar power installed, of which 146 MW (35%) was installed in the last 12 months.
In 2009, the average turnkey price for a standard PV system of three kilowatts (kW) was about NZ$40,000; by 2019 this had dropped to approx. NZ$8,500. As of the end of December 2023, 56,041 solar power systems had been installed in New Zealand.
For new installations added in December 2023, the average residential system size was 6.1 kW and the average commercial system was 46.9 kW. The largest solar power system on a school in New Zealand was officially opened in a ceremony in February 2019 at Kaitaia College.
The largest solar power system on a school in New Zealand was officially opened in a ceremony in February 2019 at Kaitaia College. Kelvin Davis, unveiled a plaque to acknowledge the installation of the 368 solar panel project which is spread across the rooftop of multiple buildings on the school campus.
Going solar helps the environment - it creates clean, green energy and is a great way to reduce your carbon footprint. Going solar demonstrates your commitment to sustainability and will help New Zealand achieve its target of net zero greenhouse gas emissions by 2050. Is your property suitable for solar?

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.. 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 10-15 Solar Panels to power their home.. 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.. A 6kW solar panel system produces enough electricity to match the average New Zealand household's consumption of grid produced electricity (which is 7,000kWh a year). [pdf]
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.
Solar power systems for households rarely go above 10kW in size. A 6kW solar panel system produces enough electricity to match the average New Zealand household's consumption of grid produced electricity (which is 7,000kWh a year). However, matching a system size to your power demands won't eliminate your power bill.
Let’s consider the Mitsubishi Electric online calculator for solar in New Zealand. This is a really simple calculator that recommends you a solar system size based upon power bill data. All you do is plug in your location, average monthly power usage and average cost of each unit (kWh) or electricity. Then hit Get Recommendations.
A 3kW grid connected solar power system has proved to be a popular system size in New Zealand, due to the fact that it will make a significant change to your power bill and is relatively affordable (around $8,000). A 3kW system in Auckland generates approximately 3740kWh/year.
Residential installations in NZ can vary from a small 1.5 kW installation, up to sizable three-phase solar systems of 8 – 10 kW. At the end of 2016, there were around 11,000 residential and small commercial solar installations according to the Electricity Authority.
For households, this would commonly be a System with a maximum output of 5kW, with commercial operations generally requiring Systems of 6kW and over. Check out this guide by Unison NZ to calculate the size of the Solar Panel System your home will need.
