Are you weighing up solar installation in NZ but worried about the upfront cost? You’re not alone. The good news: more Kiwis than ever can access tailored finance options to make installing a solar system at home affordable and hassle-free. Here’s a clear summary of what’s available, and how to find the best fit for your home.
Why Finance Solar in NZ?
Solar installations are more affordable than ever, and thanks to record-high power prices and innovative banking products, families can beat rising bills while shrinking their carbon footprint. Instead of waiting years to save up, use finance to start saving on energy costs today, often with repayments that are offset by your monthly bill savings.
Bank Green Loans and Mortgage Top-Ups
NZ’s big banks now offer attractive “green loan” packages for solar and other energy-efficiency upgrades. Key options include:
- ANZ Good Energy Home Loan: Up to $80,000 at 1% p.a. fixed for three years. For solar and other eco-home upgrades. Must be a new or existing ANZ home loan customer—eligibility and T&Cs apply.

- Kiwibank Sustainable Energy Loan: Existing home loan customers can borrow $5,000+ for solar or other renewables. Kiwibank contributes up to $2,000 across four years towards your repayments (structured as $800 in year one, then $400 annually for the next three years), plus, there’s no loan top-up fee.
Interest-Free Consumer Finance: Q Card & Mastercard
Consumer credit options offer flexibility if you’d rather keep your mortgage untouched. AA Solar 48-Month Interest-Free Offer: In partnership with Q Card, AA Solar customers can finance residential solar systems over $10,000 (or RV/holiday home installations over $5,000) with four years of 0% interest. Minimum payments apply, and there are standard fees
