Sustainable Finance Options for Solar
Thinking about going solar but unsure how to fund it?
You’re not alone. Many New Zealand homeowners want to switch to solar but prefer flexible ways to pay for it. The good news is, several major banks now offer green home loan options that make solar panels and battery systems easy and affordable to install — without a big upfront cost.
Make Solar Affordable and Sustainable
Installing solar power is more achievable than ever thanks to New Zealand’s major banks offering sustainable finance options. These special loans allow you to add solar panels, home batteries, or EV chargers at discounted or interest-free rates so you can start saving on power straight away. These are some of New Zealand’s banks currently offering finance for solar.

How It Works
Getting started is simple. First, choose the solar system size that best suits your home for example, a 5 kW setup with or without a battery. Then apply for a green home-loan top-up through your bank.
Once approved, our team designs and installs your system so you can begin generating clean power straight away.
You’ll enjoy lower electricity bills immediately and repay the system over time through your mortgage at a low, sustainable rate. With the right finance in place, solar becomes not just an environmentally conscious decision but a smart long-term investment for homeowners in Wanaka, Hawea, and across Central Otago.
