Worried about the cost of going solar? Green loans offer low or zero-interest finance to help Kiwis power their homes sustainably—without the big upfront bill.
As more Kiwis embrace renewable energy, green loans have emerged as a practical way to tackle the upfront costs of solar power. These specialised financing options—offered by major New Zealand banks—make it easier than ever for homeowners to invest in solar panels, battery storage, EV chargers, and energy-efficient appliances.
Whether you're looking to future-proof your home or reduce your power bills, green loans are designed to support your journey to a more sustainable lifestyle.
What Are Green Loans?
Green loans are low- or zero-interest financial products that help fund environmentally friendly home upgrades. In New Zealand, these often come as mortgage top-ups or personal loans tailored for energy-efficient installations—like solar systems.
They remove one of the biggest barriers to going solar: upfront cost. Instead of paying everything at once, you can spread the investment out over several years while enjoying energy savings from day one.
