Thin-film solar modules in Auckland New Zealand

What is solar panel technology?

Solar Panel technology is fast-evolving, with a range of different solar cells being used. In most cases, solar panels have multiple photovoltaic (PV) ‘cells’ created from semiconductive materials. Typically in a residential or business application there will be multiple solar panels to generate the amount of power required to be useful.

How much does a solar system cost in NZ?

We recommend you read Consumer NZ's report on grid-tied PV solar systems with a section on quoted prices. Remember the cost is going to vary on some or all of the above factors. If you need a figure to start from, we’d suggest budgeting at least $10,000 for a standard solar power system.

How many solar panels are installed in New Zealand?

In October 2022, Electricity Authority data showed 43,641 solar systems installed across New Zealand, adding up to 240 MW. This makes up an estimated contribution of under 1% of total electricity consumption. Globally, solar PV uptake has increased significantly over the past decade.

Why are monocrystalline solar panels better than thin-film solar panels?

Because monocrystalline material is more efficient than other types of photovoltaic cells, less solar panels - and therefore space - is required to generate power compared to polycrystalline or thin-film variants. They also tend to last longer and perform better in higher temperatures.
