Incentives & Financing
What solar incentives are still available in Hawaii in 2026
The federal homeowner credit ended after 2025. Review current state guidance, approved prices and financing options before budgeting your system.
The federal Residential Clean Energy Credit is no longer available for new homeowner solar or battery purchases after December 31, 2025. Separate business and third-party-owned system incentives have different rules. Confirm eligibility with a qualified tax professional.
Hawaii state incentives
For current state guidance, see our Hawaii solar tax credit guide. Confirm the current eligibility requirements, filing forms and treatment of your installation with your tax professional before including any credit in your budget.
County exemptions and utility programs have separate eligibility and enrollment rules. Verify them with your county and Hawaiian Electric. A closed program should not be counted as an available discount.
What solar costs in 2026
Approved Oahu and Maui cash prices before incentives range from $20,000-$21,000 for 5 kW to $44,000-$46,000 for 15 kW, using REC Alpha 460W panels. An 8 kW system costs $29,000-$30,000, or about $42,000-$43,000 with one Powerwall 3. Kona and West Hawaii pricing is approximately $5,000 higher. Roof and electrical changes are confirmed at the site survey.
See Hawaii solar prices for the complete breakdown. Most IEH customers see approximately 6-8 years of cash payback or 4-6 years with a Participate Energy prepaid lease. These are typical ranges, not guaranteed outcomes; usage, system size and utility rules affect results.
Purchase, financing and prepaid leases
IEH offers cash purchase, financing through HSFCU and HOCU, and a Participate Energy prepaid lease with an upfront payment approximately 30% below comparable cash pricing. This is not a homeowner federal tax credit or a zero-down monthly lease. IEH does not offer PPAs. Financing is subject to credit approval, and rates and terms may change.
Review lease versus buying and compare actual lender disclosures and lease terms before deciding.
Before you sign
Check roof life, shade and your actual electricity use. We recommend at least 15 years of roof life remaining or replacing the roof first. A battery can help with evening energy use and selected-circuit backup, but solar without batteries remains available. Savings and runtime depend on system design, loads, stored charge, weather and utility rules.
Independent Energy Hawaii has 2,000+ installations and 300+ five-star Google reviews. Every new install includes the first year of SolarServe Standard, normally $499/year; ongoing membership after that year is separate.
