Unlocking Solar Savings: Federal and State Tax Credits for Maui Homeowners
Maui’s abundant sunshine and skyrocketing electricity rates make solar energy a smart investment for homeowners across the island, from the sunny shores of Kihei to the bustling streets of Kahului, the cooler elevations of Kula, and the lush landscapes of Haiku. With Hawaii’s average residential electricity costs around 40 to 45 cents per kilowatt-hour far exceeding the national average—installing solar panels not only slashes utility bills but also provides crucial energy independence from frequent power shut downs and ongoing utility rate price hikes.
Whether you’re dealing with wildfire-related outages or rising costs from Hawaiian Electric, solar empowers Maui residents to generate their own clean power, ensuring reliability and long-term savings while reducing your carbon footprint. In this post, we’ll dive into the federal and state solar tax credits, how they work, and why acting now is essential.
The federal Investment Tax Credit (ITC), or Residential Clean Energy Credit, delivers a 30% credit on your solar installation’s total cost
Installation’s cost covers the full amount consisting of panels, inverters, batteries, wiring, and labor. No dollar cap means a $50,000 system could yield a $15,000 credit against your federal taxes next year. This non-refundable credit reduces your tax liability directly, with unused amounts carrying over to future years. To qualify, the system must be at your primary or secondary U.S. residence, and you must own it (no leases or PPAs). However, this incentive ends at the close of 2025, as per the latest big beautiful bill passed by the current administration, which terminates the residential credit to shift priorities.
Federal tax credits are facing out at the end of 2025
Installations must be completed by December 31, 2025, to secure the full 30%—missing this could cost thousands amid rising utility rate price hikes.
Hawaii State solar tax credits
Hawaii’s Renewable Energy Technologies Income Tax Credit (RETITC) complements this with up to 35% of your system’s cost, capped at $5,000 per 5kW of installed PV power. If you install 10kWp of solar power then you can claim 2 systems so $10,000 on your state taxes via Form N-342. Stack it with the federal credit for up to over 50% total savings if designed efficiently, and unused portions carry forward up to eight years at least. This is perfect for Maui homeowners who live in Lahaina, Wailuku, Kahului, Kihei, Kula, or Haiku seeking energy independence.
Combining credits is simple with planning. A 8 kW system on Maui might cost $45,000-65,000 pre tax credits, dropping to $22,000-$30,500 net after 30% federal and $10,000-$15,000 state credits respectively. Add annual savings of $2,000–$3,000, and ROI hits under five years—vital against power shut downs and utility rate price hikes.
With the federal deadline approaching, permitting and supply issues on Maui could jeopardize your project. At NETZERO ENERGY, we’re your local experts helping homeowners and friends all over the island to build custom solar systems in time for the 2025 window. The systems need to be set in operation and have passed County electrical inspection in 2025 to be eligible for the tax credits in 2026.
As a small Maui-based team, owned by Andonis Kapsalis, Electrical Engineer in trade, we can handle your project from design to the final turn-key solution in time for top-quality service.
