New Zealand PV energy storage power station budget

Is solar PV a viable option for New Zealand households?

This is the first study in New Zealand to use detailed and high-quality data for both solar supply and residential demand. It shows solar PV is likely to be financially viable for a significant proportion of New Zealand households, particularly for those who consume a lot of energy.

How much does the New Zealand battery project cost?

The almost $140 million (NZD 150 million) battery project, which is scheduled to be operational by late 2026, is the first phase of a planned multi-stage development that is expected to deliver up to 400 MW / 800 MWh of energy storage capacity at the site, about 100 kilometres south of Auckland.

Why do PV solar systems vary in New Zealand?

varies substantially by location in New Zealand due to weather patterns, naturally throughout a day, and by season and latitude with sun angle. Combined with the low efficiency of PV modules and electrical losses, the capacity factor of PV solar systems in New Zealand varies substantially, as shown in Figure 5.

Will the New Zealand dollar change the cost of PV systems?

Since many PV components are imported, fluctuations in the New Zealand dollar could change the cost of systems in New Zealand. This may counter reducing rate of return requirements, although other generation technologies are likely to be similarly affected by exchange rate fluctuations.

Does the Electricity Authority support solar PV & energy storage?

Both solar PV and energy storage have seen increasing support from the Electricity Authority. Indeed, the organisation is actively looking to improve regulations to support more investment in energy storage and new generation, including residential solar PV, to enhance the security of supply.

Where should solar panels be installed in New Zealand?

Most solar PV panels in New Zealand are installed facing as close to north as possible to maximise total electricity generation. However, some homeowners choose to install east- and west-facing arrays to try and match their solar generation and energy use more closely. Here’s how they compare:
