FAQ

Have Questions?
Ask Us

How much can I save with solar panels in New Zealand?

What you can save depends on serval key factors

System size (kW) and annual generation (kWh)
Your household electricity use and when you consume it (daytime self consumption saves most)
Retail electricity price you pay (higher prices = faster payback)
Whether you export surplus and the export credit/feed in rate (usually low)
Installation cost, roof orientation, shading, and local weather

But many NZ households save several hundred to a few thousand a year with typical paybacks of 4-8 years.

How long does solar panel installation take?

From initial enquiry to system being installed this can take around 2-8 weeks.
Installation of on-roof install usually takes 1-3 days.

Do solar panels work in New Zealand's climate?

Yes - solar panels work well across New Zealand and are a practical way to generate electricity year round. NZ Sunlight gets strong solar radiation (especially in summer and clear autumn/spring days), so panels generate well. With the Cooler temps PV efficiency is slightly higher in cooler conditions, so NZ’s mild climate is favourable.

What is the cost of solar panels in New Zealand?

In New Zealand the cost of installing solar panels depends on the size of the system, whether you include batteries and the quality of components and installation.

Can I sell excess solar power back to the grid in NZ?

Yes, in New Zealand you can sell excess solar power back to the grid if your system is grid-connected and you have the correct meter installed. Your electricity retailer will pay you a buy-back rate (usually as a credit on your bill), but rates vary with each retailer so it pays to shop around!

What solar panel brands does World Solar use?

World Solar NZ works with a range of well-known solar brands when supplying and installing systems in New Zealand. We source panels, inverters and battery/storage products from industry-recognised manufacturers such as; Sig Energy, Trina, Tesla.

What is the payback period for solar panels in New Zealand?

Payback period can vary, but most are between 4-10 years.

Do I need battery storage with my solar system?

You don’t need battery storage for a solar system to work, a standard grid-connected system will power your home during the day and export any excess back to the grid. However, a battery can be useful if you want to use more of your own solar power at night, reduce peak power charges, have backup power during outages and increase energy independence.
