Through a partnership with Kauai Community Federal Credit Union (KCFCU) and Kauai County Housing Agency (KCHA), the Kauai Island Utility Cooperative (KIUC) provides qualifying members with zero-interest loans for solar water heating systems. The loan is available for installations of new systems, or to replace solar water heating systems that are over 15 years old and no longer work. KCHA, with funding from the Community Development Block Grant Program, and KCFCU provide funding for the loans. KIUC pays the interest, markets the program and verifies that systems will meet Energy Wise program standards for sizing and installation.
Participants must repay the loan within 60 months (no down payment is required). KIUC pays the interest on the loan directly to the lender for the customer. Participating members also make their monthly payments directly to the lender. There is no maximum loan amount, however commercial systems are not eligible.
The State of Hawaii also offers tax credits for solar water heating systems.
