Green finance

Finance
the switch.

Most major NZ banks offer low- or zero-rate green loans for solar. As a SEANZ-approved installer, Solar One qualifies for all of them — so you can spread the cost and start saving from day one.

The green-loan lineup

Indicative rates

Here's the current lay of the land across the big banks. Most require your home loan to be with that bank, and an approved-installer quote — which we provide as standard.

ANZ Up to $80,0001% p.a. fixed for 3 years
BNZ Up to $80,0001% p.a. for 3 years · flexible terms
Westpac Up to $50,000Interest-free for 5 years
ASB Up to $80,000Low fixed green rate · 3-year term

Also worth a look: Kiwibank offers a cash contribution on lending over $5k for energy-efficiency upgrades. Most green loans require your home loan to sit with that bank.

Rates and terms are indicative and set by each bank — check current details and eligibility directly with them. This is general information, not financial advice. We're happy to help you navigate the options.

How green finance works

01

Choose your bank

Pick the green loan that suits you. Most are only available if your home loan already sits with that bank.

02

We quote it

You get an itemised quote from a SEANZ-approved installer — exactly what the bank needs to see for the application.

03

They fund the install

The bank finances your system at the green rate. You pay it back over the term, offset by the power you're no longer buying.
