What Hawaii pays for your exported solar power
Export compensation is the single biggest payback lever in 2026. Here is Hawaii's current rule in plain words, with the official source.
Under Hawaii's export rules, compensation for surplus power decides the payback - which typically runs 10-14 years on unsubsidized 2026 math.
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.
Beware of any 2026 payback estimate that looks as good as the 2025 ones: with the federal credit gone, a third of the old subsidy math vanished. If a sales projection has not gotten noticeably worse since 2025, it is hiding something - usually an inflated utility-rate escalation assumption.
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.
The 2026 numbers
| System size | Installed price (marketplace avg) | Notes |
|---|---|---|
| 6 kW | $15,480 | Small roof / low usage |
| 8 kW | $20,640 | Typical starter system |
| 10 kW | $25,800 | Family home with AC |
| 12 kW | $30,960 | Large home / EV charging |
| Home battery (optional) | $12,000-$16,000 | Backup power + self-consumption |

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.

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
Is there still a federal solar tax credit in 2026?
No. The 30% Residential Clean Energy Credit was repealed effective for systems placed in service after December 31, 2025, per the IRS. Only systems finished by the end of 2025 qualified. State-level incentives are separate and some survive - check the state page in this guide.
What is net metering and why does it decide everything?
It is the rule for how your utility credits electricity you export. Full retail net metering credits exports at the same rate you pay - the grid works like a free battery. Net billing or avoided-cost rules pay far less per exported kWh, which lengthens payback and strengthens the case for a home battery.
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.
Is solar still worth it without the federal credit?
It depends mostly on your state's export rules and your daytime usage. Paybacks lengthened by roughly a third when the credit ended, but rising electricity rates and record-cheap hardware keep the math workable in states with decent export compensation - and marginal where exports pay avoided cost only.
Should I lease, get a PPA, or buy?
Buying keeps all savings and any incentives with you. Leases and PPAs put a company's equipment on your roof for 20-25 years, complicate a home sale, and in 2026 any tax benefits they advertise belong to the company under commercial rules - not to you. Read escalator clauses carefully.
