Financing A Solar Power System Purchase

Solar power systems will save any home in New Zealand considerable amounts of money over time. Financing can help with the initial up front cost of the solar power system. There are several ways you can finance a solar power system:

1. Topping up a home mortgage with a green loan
2. A personal loan

1. Financing Solar With A Mortgage Top Up

Often called a green loan, this is the cheapest way to finance solar and batteries in NZ. Offered by ANZ, ASB, BNZ, and Westpac, it’s essentially a mortgage top-up - so you’ll need to have a mortgage to qualify.

Green Loan Eligibility

Banks will check if you can afford the loan, much like a home renovation loan. You’ll usually need at least 20% equity. Not sure if you qualify? Just apply — it never hurts to ask!

2. Financing Solar With A Personal Loan or Interest-Free Financing

Those offering this type of finance include Q Card, Gem Visa, Q Mastercard and Finance Now.

Companies like Q Card often have deals where you don't have to pay interest on your first year, but from the second year onwards interest creeps up to around 26% p.a..

Buyers should exercise caution; interest-free doesn't always translate to "free". Often in the first year of these 'interest-free' loans the fees can amount to an equivalent of paying 10% p.a..

Personal loans will work for many people as long as the loan is paid off within the interest-free time period. However, if left longer the benefit of cheaper electricity bills from installing solar power will be outweighed by the cost of interest incurred on the loan.
