How payback works

Estimated payback

Saved per year
Solar's return is its payback period: annual bill savings against net system cost. In 2026, without the federal credit, that payback is longer but still real where rates and net metering are favorable.
Spot a fair quote in Haiku-Pauwela
A typical solar installation here runs $21,500–$28,100. A trustworthy quote shows a production estimate (kWh/year) and the net cost after incentives, not just a monthly payment. Be cautious of door-to-door pressure.
- Get the production estimate in kWh and the net cash price.
- Confirm the net-metering rate your utility currently pays.
- Compare buying vs lease/PPA; ownership keeps the long-run return.
What changes your price
- System size (kW). Sized to your annual usage and roof space; bigger arrays cost more but produce more.
- Panel tier & inverter. Premium high-efficiency panels and microinverters cost more per watt.
- Roof complexity. Steep, multi-plane, or shaded roofs add labor and may need more equipment.
- Battery storage. Adding storage roughly increases project cost by half but adds backup power and self-use value.

Why it matters
Why it pays to do it right
Lock in your electricity rate
Solar trades a volatile monthly bill for a fixed up-front cost, hedging against future utility rate increases over the system's life.
Payback is the real question
With the federal credit gone in 2026, the honest math is production times your local rate versus net cost. We show that payback plainly, no inflated promises.
Net metering rules drive the return
Where your utility still offers it, net metering credits the power you export, and that buyback rate is often the single biggest swing factor in your return. Several states have scaled it back, so confirm your utility's current policy.
Pairs with a sound roof
Panels last 25+ years, so install on a roof with plenty of life left. If your roof is near end-of-life, replace it first.
Local conditions
Solar in Maui
Rooftop solar in Haiku-Pauwela has some of the best fundamentals in the country: Maui's residential electricity averaged about 42 cents per kWh in 2025 (and around 48 cents on Molokai), the island gets roughly 5.8 peak sun hours a day, and Hawaii's 35% state solar tax credit remains in force even though the federal credit expired.
Electricity rate
~42 cents/kWh
Every kilowatt-hour a Haiku-Pauwela system produces avoids some of the priciest grid power in the nation, compressing payback despite island installation costs.
State solar tax credit
35% (up to $5,000)
Hawaii's Renewable Energy Technologies Income Tax Credit still applies for 2026 even though the 30% federal credit expired at the end of 2025; confirm current rules when you file.
Peak sun hours
~5.8/day
Microclimates matter in Maui: Kihei and Wailea roofs bake all year while windward homes see more cloud, so a site-specific production estimate is worth insisting on.
Hawaii's 35% state credit and today's programs
The federal 25D credit (30%, no cap) expired December 31, 2025, so 2026 cash buyers in Haiku-Pauwela get no federal credit. Hawaii's Renewable Energy Technologies Income Tax Credit still covers 35% of system cost, capped at $5,000 for a single-family home, though lawmakers have moved to scale the program back in coming years, so confirm the current rules when you file. Net metering closed long ago; new Haiku-Pauwela systems enroll in Customer Self-Supply, Smart Export, or the Bring Your Own Device Plus battery program (the successor to Battery Bonus, which closed to new participants in 2024). With those rates, most installers pair panels with a battery, and leases or PPAs can still tap the business 48E credit through 2027.
Permits
Solar in Haiku-Pauwela needs a County of Maui building and electrical permit via the DSA MAPPS portal plus Hawaiian Electric interconnection approval before energizing.
FAQ
Solar questions, answered for Haiku-Pauwela
Is solar still worth it in Haiku-Pauwela after the federal credit expired?
Yes, more than almost anywhere in the US. The 35% state credit (capped at $5,000) still applies, and offsetting 42-cent power does the heavy lifting; typical Haiku-Pauwela systems pay back faster than mainland systems did even with the old federal credit.
What happened to net metering in Maui?
Hawaii's original net energy metering closed to new applicants years ago. New Haiku-Pauwela systems choose among Customer Self-Supply (use what you make), Smart Export (export at set rates, mainly evenings), and Bring Your Own Device Plus, the battery program that replaced Battery Bonus when it closed to new participants in 2024.
How does the Hawaii state solar credit work for Haiku-Pauwela homeowners?
The Renewable Energy Technologies Income Tax Credit covers 35% of the installed cost of a PV system, capped at $5,000 for a single-family home, claimed on your Hawaii income tax return. Lawmakers have moved to tighten the program in coming years, so verify the current rules with your tax preparer when you file.
Do I need a battery with solar in Haiku-Pauwela?
Strongly recommended. Without retail net metering, a battery stores midday production for expensive evening hours, qualifies for Bring Your Own Device Plus incentives, and keeps essentials running when storms or fire-weather shutoffs interrupt power.
How much will a system produce in Haiku-Pauwela?
At roughly 5.8 peak sun hours, a 6 kW system generates around 9,500 kWh per year, with leeward roofs in Kihei and Wailea at the high end and windward sites somewhat lower. Production stays consistent year-round at Maui's latitude.
