A Local Credit Union That Cares

Renewable Energy Loans

Wailuku Federal Credit Union is proud to offer loans for environmentally conscious home improvements. Specifically, we offer exceptional rates on loans used for the installation of solar water heaters and photovoltaic (electricity-producing solar panel) systems.

Solar Water Heater Loans

If you are switching from an electric or gas water heater to a solar water heater – or replacing an existing water heater (restrictions apply) – we offer loans at 0%. This offer is made available to you through Hawaii Energy’s Hot Water, Cool Rates program. Learn about solar water heating and Hawaii Energy's Hot Water, Cool Rates program.

Photovoltaic Loans

If you are looking to finance the purchase of a photovoltaic system, your monthly payment will be about the same as your monthly electric bill (or may even be lower). Therefore, your cash flow will likely not decrease while you pay for your loan, and you will see huge savings once your system is paid for. Installing a photovoltaic system is a way to help both our environment and your pocketbook.

I have been doing business with Wailuku Federal Credit Union for 11 years now. Walking into the branch feels like stepping into one of my family member’s home. I’m always greeted by a friendly face such as the team members Alyssa, Kellie, and Brandi just to name a few. Mahalo Wailuku FCU for treating me like family.
