Here are some of the questions you may be thinking about before you look at having solar installed at your home.

Can I get finance for solar installations from my bank?
Are there free interest rate options?
Can I include solar panels in my home loan?
Which bank in New Zealand gives the best loan interest for solar panels?

We suggest looking ok at your bank first; after all, most of them will already have some interest in your property by way of a mortgage or security.

In New Zealand, many large banks provide solar finance to homeowners. The main four are ASB, ANZ, Westpac, and BNZ. All offer Solar finance loans, which are separate from your mortgage.

What is a great interest rate for a solar loan?

Solar loans are widely available, including deals with your installer. However, when you look at the four main banks offering between zero and 1% loans, we think talking with your bank is a no-brainer option. Just one word of precaution. Once the loan is out of its free period with any financial institution, please check the new interest rate. Some institutions can be as high as 20% after 12 months. So read the fine print.
