Solar financing guide

Flexible Payment Options for Every Budget

Choosing the Right Solar Financing Option

Investing in solar is a smart way to reduce power bills and increase energy independence. A well-planned system not only saves money but also delivers a stronger return than traditional savings accounts. As energy prices continue to rise, solar becomes an even wiser investment.

At Bay of Islands Solar, we create systems tailored to your needs—whether you’re looking to maximise energy production, reduce reliance on the grid, or see the fastest return on investment. We simplify the financing process, helping you explore your options with a clear breakdown of savings and when you’ll break even.


How to Fund Your Solar Investment

If you have savings set aside, self-funding your solar system offers the highest return on investment. With no interest costs, every dollar saved on your power bill goes directly back into your pocket. As electricity prices rise, your return on investment only improves over time.
