Paying for solar doesn't have to mean writing one big check. Many Oahu families finance their solar panels, battery storage, roofing or air conditioning so the monthly payment sits alongside, or replaces part of, their Hawaiian Electric bill. This page explains the solar loan options available through our lending partners, what each one offers right now, and how to compare them before you sign.
For a broader look at cash, loans and payment planning, see our guide to solar financing in Hawaii.

Your loan options
Solar PV & solar water heating
Hawaii State FCU offers a dedicated photovoltaic (PV) loan for solar systems in Hawaii. For rates effective November 1, 2026, the credit union lists:
A few rules to know. Membership in Hawaii State FCU is required, and the credit union notes that Hawaii residency is required for new accounts. The PV loan is available only for systems installed by participating contractors, and it can't be used to refinance an existing PV loan. We'll help you confirm your project qualifies before you apply.
The 0% period can line up nicely with the first stretch of your system's production, but plan ahead for when regular payments begin in month 19.
Roofing & renovations
If your roof needs work before solar, or you're planning other upgrades, Hawaii State FCU's Roof and Renovation loan lists 0% interest and no payments for the first 12 months, then rates as low as 7.70% for the remaining 72 months of a 7-year term (with a full-term APR as low as 5.691%). The maximum is 75,000 dollars, subject to approval, and membership is required. Like the PV loan, it's offered through participating contractors.
Not sure whether your roof is ready? Read whether to replace your roof before solar and see our solar roofing services. Planning new energy-efficient air conditioning at the same time? Ask us which loan fits that part of the project.
Solar, storage & roofing
Sungage Financial provides online solar loan financing for solar, storage and roofing projects. Sungage notes that it isn't the lender: loans arranged through its portal are issued by Hatch Bank, and Sungage doesn't operate in every state. Rates, terms and eligibility are quoted during the application, so compare the full offer, including APR, term and any fees, with your other options.
Two loans with similar monthly payments can cost very different amounts over time. Before you choose, compare:

Incentives change how much you need to borrow, and they've changed recently. The IRS says the Residential Clean Energy Credit isn't available for home systems placed in service after December 31, 2025. Hawaii's state renewable energy tax credit rules have also been updated; see our guide to the Hawaii solar tax credit and confirm your situation with a tax professional.
If you add a battery, Hawaiian Electric's battery program may also be part of the picture. Our 2026 HECO BYOD Plus guide explains how it works, and our battery storage page covers Tesla Powerwall and Enphase options.

Most Oahu homeowners pay cash or use a loan. Through our lending partners you can apply for a Hawaii State Federal Credit Union PV loan, which starts with 18 months at 0% interest and no payments, or a solar loan through Sungage Financial. Lender approval, rates and terms depend on your credit and are set by the lender.
For rates effective November 1, 2026, Hawaii State FCU lists 0% interest and no monthly payments for the first 18 months, then rates as low as 7.70% APR for the next 78 months, a 96-month term, a maximum of 75,000 dollars, no prepayment penalty and required membership. Check the credit union's site for current terms before you apply.
No. Hawaii State FCU says its PV loan is available only for systems installed by participating contractors, and it can't be used to refinance an existing PV loan. Ask us to confirm eligibility for your project.
Hawaii State FCU offers a separate Roof and Renovation loan with 0% interest and no payments for the first 12 months, then rates as low as 7.70%, over a 7-year term. Some projects pair new roofing or AC with solar; we'll help you sort out which loan fits each part.
The IRS says the Residential Clean Energy Credit isn't available for home systems placed in service after December 31, 2025. Hawaii's state tax credit rules have also changed; see our Hawaii solar tax credit guide and confirm with a tax professional.
Cash avoids interest, while a loan spreads the cost so payments can line up with your Hawaiian Electric savings. Compare the total cost of each option, not just the monthly payment.
