Is there still a solar tax credit for Urban Honolulu homeowners in 2026?
The 30% federal credit is gone for 2026 installations. What survives for Urban Honolulu: Hawaii's own incentives and tax treatment - verified against state sources.
The 30% federal solar tax credit ended for installations finished after December 31, 2025 - Urban Honolulu systems completed in 2026 get $0 from it.
Installed home solar for Urban Honolulu homeowners averages about $2.58 a watt across the U.S. marketplace - roughly $30,960 for a 12 kW system before incentives.
Urban Honolulu, Hawaii has about 344,967 residents, and its solar quotes are built from system size, roof complexity and export rules - not the town name.
The federal Residential Clean Energy Credit - the 30% one every solar ad still quotes - was repealed by the One Big Beautiful Bill Act signed July 4, 2025. Per the IRS, it is not available for any system placed in service after December 31, 2025, and 'placed in service' means the installation completion date, not the contract date.
If a salesperson in Urban Honolulu tells you a 30% federal tax credit applies to your 2026 installation, they are quoting a dead law. What may still exist: Hawaii's own incentives and tax treatment, listed below, and lease/PPA arrangements where a company claims commercial credits - in which case the credit belongs to them, not you.

The 30% federal tax credit is gone for 2026 installations
The federal Residential Clean Energy Credit (30%) was repealed by the One Big Beautiful Bill Act signed July 4, 2025. Per the IRS, the credit is not available for any property placed in service after December 31, 2025 - and the IRS counts the installation completion date, not the contract date.
Hawaii rules that decide your payback
| Rule | Hawaii status |
|---|---|
| Export compensation (net metering) | Full retail net energy metering is closed to new customers in Hawaii, and the interim successor tariffs — Customer Grid Supply, Customer Grid Supply Plus, Interim Smart Export and Customer Self-Supply — also closed to new enrollment in early 2024, so new rooftop solar customers now enroll in the Smart DER Tariff, choosing either an Export Rider paying time-varying export rates or a Non-Export Rider for self-consumption only. |
| State incentive | Renewable Energy Technologies Income Tax Credit (RETITC), HRS §235-12.5 — 35% of actual installed cost, capped at $5,000 per system for solar photovoltaic on single-family residential property (a separate $2,250 cap applies to solar water heating) |
| Sales tax on the system | Not exempt - taxed like any purchase |
Hawaii has by far the highest electricity prices in the nation — 52.00 cents/kWh residential in May 2026 against an 18.44 cent US average (EIA) — which makes rooftop solar unusually valuable, but grid saturation means full retail net metering has been closed for years and new systems are steered toward self-consumption and batteries rather than exporting, so a solar-plus-storage design is usually the one that actually pays.

What this means for Urban Honolulu roofs
Whether solar still pays in Hawaii after the federal credit's end comes down to arithmetic, not ideology: installed cost (about $2.58 a watt at the marketplace average), what your utility pays for exports, and how much of your generation you use yourself. High self-consumption - daytime usage, EV charging, batteries - is now the biggest lever.

Getting Urban Honolulu quotes
Before requesting quotes, have your last 12 months of electricity bills handy - system sizing should follow your real usage, not a salesperson's template. A bid sized far above your usage is a margin play, especially now that surplus export pays less in most states.

Common questions
Does solar raise my property taxes?
It depends on the state - many exempt solar's added home value from property tax, others do not, and some exemptions have expiration dates. This guide's state page lists the verified rule and source for your state.
How much does home solar cost in 2026?
The U.S. marketplace average is about $2.58 per watt installed - roughly $15,500 for a 6 kW system and $31,000 for 12 kW, before any state incentives. Quotes meaningfully above that level deserve a written explanation of what justifies the premium.
What happens if my installer goes out of business?
Panel and inverter warranties come from the manufacturers and survive, but the workmanship warranty usually dies with the company. That is a real risk in the post-credit shakeout - prefer installers with years of local history, and get manufacturer-backed workmanship coverage where offered.
Is my roof even suitable for solar?
Three things decide it: orientation (south-facing is best in the U.S., east-west workable), shade (trees or taller buildings across midday hours can sink the math), and roof age (if the shingles have under 10 years left, reroof first - removing and reinstalling panels later costs thousands). Any honest installer assesses all three before quoting a number.
Do I need a battery with my solar?
Not necessarily. Under full retail net metering, the grid effectively stores your surplus for free. Batteries earn their $12,000-16,000 price where export rates are low, outages are common, or time-of-use rates make evening self-consumption valuable.
