Thinking about going solar? You’re not alone. With energy prices on the rise and sustainability becoming a priority for Kiwi households, solar panels are a smart investment. But one of the first questions homeowners ask is: “What is the solar panels price in NZ?” In this guide, we break down current costs, what affects pricing, and provide affordable solar panel price NZ Options for every budget in 2025.
What Is the Average Solar Panels Price NZ?
As of 2025, the average price for a fully installed residential solar panel system in New Zealand ranges between $1,700 and $2,300 per kilowatt. This means a typical 5kW system might cost around $9,000, while a larger 10kW system could be closer to $15,000 to $18,000.
The actual cost will vary depending on your home’s size, your energy usage, and the installer you choose. Some providers offer discounted package deals, especially if you live near major cities like Auckland, Wellington, or Christchurch.
What Affects Solar Panel Pricing in New Zealand?
Several factors influence how much you’ll pay for solar in NZ:
System Size
The bigger your system (measured in kilowatts), the more panels and hardware are required. While the total cost increases with size, the cost per kilowatt usually decreases, giving you better value at higher capacities.
Type and Brand of Panels
High-efficiency panels from trusted brands like Longi, JA Solar, or Trina Solar often cost more upfront but offer better long-term output and warranties.
Inverter Type
Most modern systems come with hybrid inverters, which are battery-ready. These can cost more than standard grid-tied inverters but future-proof your investment.
Installation Complexity
A single-storey home with a metal roof is the most affordable setup. Homes with tile roofs, steep pitches, or multi-storey layouts usually require more labour and mounting components, which adds to the cost.
Location
Some solar installers include free installation within a limited service area, such as 50 kilometres from Auckland’s CBD. If you’re outside that range, there may be additional travel or freight charges.
How to Get the Best Solar Panels Price NZ
To maximise value:
- Compare full system packages — not just per-panel pricing. Look for bundles that include installation, inverters, warranties, and compliance.
- Check for finance options — Some NZ banks offer interest-free solar loans.
- Buy battery-ready — Choose systems with hybrid inverters so you can add batteries later without extra upgrades.
- Look for installer warranties — A good price means little without workmanship guarantees and local support.
