What are Green Home Loans?
Green home loans are special lending products from major New Zealand banks that help you finance sustainable home improvements – including solar panel systems – on favourable terms.
These loans can reduce or eliminate interest costs for a period and spread your investment over time rather than paying all up front.
How do Green Home Loans work?
- You may get very low or even 0% interest for a fixed term
- You borrow against your home equity, so repayments are structured over years
- Banks set eligibility criteria such as minimum loan and having an existing home loan with them
What are the benefits of Green Home Loans?
- Affordable solar financing – get solar installed now and pay gradually
- Lower upfront cost – keeps savings in your pocket
- Flexible eligibility – many loans allow heat pumps and EV chargers with solar
- Can increase property value – adding solar makes homes more attractive
- Smooth integration with your home loan – one repayment stream

Does Kiwibank offer a special rate?
Kiwibank’s sustainable energy loan doesn’t offer a low fixed rate like others but contributes cash back over time.
How soon will I save on power bills?
Once installed, a solar system starts reducing grid electricity usage, so savings begin right away. However, some energy companies will start applying credits to your usage after a few billing cycles.
To get the Green Home Loan most banks require the solar installation company to be SEANZ registered. Is StarDelta a SEANZ registered member?
