Solar power in New Zealand is increasing in capacity, in part due to price supports created through the emissions trading scheme. 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 the 12. . 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. . In July 2019 Refining NZ announced plans for a 26 MW solar farm at the , but by May 2020 the project was on hold. In February 2020 announced. . 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. . • • • • . • – Solar Energy• • [pdf]
There is currently around 270 MW of installed solar generation in New Zealand. This adds up to about the same capacity of a coal or gas fired Rankine generation unit. Out of the 270 MW of solar, about 180 MW is in the North Island and is mostly made up of rooftop solar installations.
The factors that are driving this change are not just an excellent solar energy potential, but the consistently rising electricity costs, and an ever-looming climate emergency. In New Zealand, there is enough solar energy to power our homes and communities quite easily. The country has the potential to generate 391280000 GWh per year.
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?
If current trends continue for distributed solar installations, of around 4 MW per month, the addition of these two large solar farms could see as much as 120 MW of new solar generation added in the next 12 months. This would increase New Zealand’s solar capacity by nearly 50 percent.
The darker areas on the map receive higher amounts of sunlight. New Zealand solar potential map (source - Solargis) It can be seen from the map that most areas benefit from an excellent solar irradiation level of about 4 kWh/kWp, meaning every kW of installed solar panels will generate around 4 kWh in a single day.
Here is another proof that the solar energy potential will never be a concern for NZ’s solar growth - the example of Germany. Germany has an average potential of 1088 kWh/m2 (much lower than NZ). Until a few years ago, Germany was the world’s leading country for solar installed capacity.
