What Changes for Hawaii Solar Installations in 2027
Hawaii's solar tax credit survives into 2027, but a potential statewide funding cap, income limits and an advance certification process mean your credit amount may no longer be guaranteed. Review official guidance and your tax advisor before budgeting for incentives.
Homeowners buying solar in 2026 do not qualify for the expired federal Residential Clean Energy Credit. Hawaii’s state solar incentive is separate and has its own eligibility, timing and application requirements.
Check the current state rules
Review the Hawaii State Energy Office incentives page and confirm current guidance with a qualified tax professional. State rules may change, and eligibility depends on your circumstances. Do not budget around a guaranteed credit amount.
Installation timing and eligibility
A signed contract alone does not establish eligibility. Keep your project documentation and confirm applicable installation and tax-year requirements with your tax preparer. Permitting, utility approval and inspections vary by county and property; no installation date or tax outcome is guaranteed.
Compare prices before incentives
Start with the actual cost of your solar system, equipment and add-ons. Our Hawaii solar cost page publishes cash prices before incentives, with Oahu and Maui base prices and the Kona/West Hawaii adder.
Prepaid leasing is not a homeowner tax credit
Participate Energy’s prepaid lease may cost about 30% less upfront than an equivalent cash purchase, subject to the proposal and agreement. That price difference is not a federal credit for a homeowner buying in 2026. See lease versus buy and ask for an itemized comparison.
