If you’re a Maui homeowner considering solar, you’re probably wondering what financial incentives are available to help offset the cost. It’s an important question, especially with recent changes to federal solar policy that eliminated residential tax credits in 2026.
Here’s the great news: while federal incentives for residential solar are no longer available, Hawaii’s state-level solar incentives remain extremely generous—and they still make going solar highly affordable for Maui homeowners. In fact, Hawaii offers some of the strongest state solar incentives in the entire nation, providing substantial cost reductions that can save you thousands of dollars on your solar installation.
Let’s break down exactly what solar incentives are available to Maui homeowners in 2026, how much you can save, and why Hawaii’s state programs still make solar one of the smartest investments you can make for your home.
Hawaii’s 35% State Solar Tax Credit: The Foundation of Solar Savings
The cornerstone of solar incentives for Maui homeowners is Hawaii’s State Solar Tax Credit, which remains one of the most generous in the country.
How the Hawaii State Solar Tax Credit Works
Hawaii offers a tax credit equal to 35% of your solar installation costs, with a cap of $5,000 per 5 kilowatts (kW) of installed solar capacity. This is a dollar-for-dollar reduction in your Hawaii state income tax liability, making it incredibly valuable.
Here’s what makes this credit so powerful: it’s a tax credit, not a deduction. A tax credit directly reduces the amount of taxes you owe, while a deduction only reduces your taxable income. This means the credit has much greater financial impact.
The credit can be claimed on your Hawaii state income tax return in the year your solar system is placed in service. If you don’t have enough tax liability to use the full credit in one year, you can carry the unused portion forward into future tax years until it’s completely utilized.
Real Examples of State Tax Credit Savings
Let’s look at what this means for actual Maui solar installations:
- Example 1: 5 kW System System cost: $17,000 State tax credit (35%): $5,000 (hits the cap for 5 kW) Your net cost: $12,000
- Example 2: 6 kW System System cost: $21,000 State tax credit (35% up to cap): $6,000 ($5,000 for first 5 kW + $1,000 for additional 1 kW) Your net cost: $15,000
- Example 3: 7 kW System System cost: $24,500 State tax credit (35% up to cap): $7,000 ($5,000 for first 5 kW + $2,000 for additional 2 kW) Your net cost: $17,500
As you can see, the Hawaii state tax credit provides substantial savings—typically $5,000 to $7,000 or more depending on your system size. This alone reduces your solar investment by more than one-third.
Who Qualifies for the Hawaii State Solar Tax Credit?
Most Maui homeowners who install solar qualify for the state tax credit. The basic requirements include:
You must be a Hawaii resident who files Hawaii state income taxes. The solar system must be installed on your Hawaii residence (primary or secondary home). You must own the solar system (leased systems don’t qualify). The system must be new equipment, not used or refurbished. You must have sufficient Hawaii state tax liability to claim the credit (or be able to carry it forward).
ProVision Solar helps all our customers understand their eligibility and assists with the tax credit documentation process to ensure you receive every dollar you’re entitled to.
The Federal Tax Credit: Important 2026 Changes
Before we continue with Hawaii’s excellent state incentives, it’s important to address the federal tax credit situation for Maui homeowners.
What Changed in 2026
For years, residential solar installations qualified for the federal Investment Tax Credit (ITC), which provided a 30% federal tax credit in addition to state incentives. However, under the One Big Beautiful Bill (OBBB) passed in 2026, the federal residential solar tax credit has been eliminated.
This means Maui homeowners installing solar in 2026 and beyond no longer receive the 30% federal credit that was previously available. The federal ITC still exists for commercial solar installations, but residential systems are no longer eligible.
Why Solar Still Makes Excellent Financial Sense
While losing the federal credit might sound discouraging, here’s the reality: solar in Maui remains an outstanding investment even without federal incentives. Here’s why:
Hawaii’s 35% state tax credit is exceptionally generous and rivals or exceeds many states’ combined state and federal incentives from previous years. Maui’s electricity rates are among the highest in the nation (often exceeding $0.35 per kWh), which means your solar savings are substantial regardless of incentives. The payback period for solar in Maui is still just 6 to 9 years even without federal credits, after which you enjoy free electricity for decades. Property values increase with solar installations, providing additional financial benefit beyond energy savings.
Many mainland states with lower electricity rates and smaller state incentives still see strong solar adoption because the long-term economics are favorable. Maui’s combination of high electricity costs and Hawaii’s strong state incentives means solar economics here remain among the best in the country.
Bring Your Own Device Plus (BYOD Plus): Battery Storage Incentives
Beyond the state tax credit, Maui homeowners can access additional incentives when adding battery storage to their solar system through Hawaiian Electric’s BYOD Plus program.
What Is the BYOD Plus Program?
The Bring Your Own Device Plus program offers cash incentives and monthly bill credits to customers who add battery storage (like the Tesla Powerwall 3) to their rooftop solar system. The program allows Hawaiian Electric to access your stored battery energy during a customer-selected two-hour daily window, helping support the grid while moving Hawaii toward its 100% clean energy goal.
Your battery always serves your home’s needs first. Only excess stored energy—energy you’re not using—is exported to the grid during your selected time window.
BYOD Plus Financial Incentives
The program provides substantial financial benefits:
- Upfront Incentive: $400 per kilowatt (kW) of battery capacity committed, with no cap on total incentive.
- Low-Moderate Income Adder: An additional $400 per kW for qualifying households, also with no cap.
- Monthly Export Credits: Ongoing bill credits for energy exported from your battery to Hawaiian Electric during peak demand periods.
These incentives are paid once after your contract is executed. If you lease your battery, the leasing company receives the upfront incentive, but you still benefit from monthly export credits.
BYOD Plus Example: Tesla Powerwall 3
Let’s say you add a Tesla Powerwall 3 with a 5 kW commitment to your solar system:
Upfront incentive: $2,000 ($400 × 5 kW) Monthly export credits: Approximately $52 per month (varies by island and rate plan) Annual bill credit value: ~$624
If you qualify for the low-moderate income adder, you’d receive an additional $2,000 upfront incentive for a total of $4,000 plus the ongoing monthly credits.
Who Should Consider BYOD Plus?
The BYOD Plus program is excellent for Maui homeowners who want:
Energy backup during power outages, maximum energy independence from the grid, the ability to store solar energy for nighttime use, additional financial incentives beyond the state tax credit, and participation in Hawaii’s clean energy future while earning credits.
ProVision Solar is experienced in integrating Tesla Powerwall 3 systems with BYOD Plus enrollment, handling all the paperwork and setup on your behalf.
Property Tax Exemption for Solar in Maui
Another valuable incentive for Maui homeowners is the property tax exemption available in some Hawaii counties.
How Property Tax Exemptions Work
When you install solar panels, you’re adding value to your property. Normally, increased property value results in higher property taxes. However, some Hawaii counties offer exemptions that prevent solar installations from increasing your property tax assessment.
Honolulu County’s 25-Year Exemption
The City and County of Honolulu (which covers approximately 70% of Hawaii’s population on Oahu) offers a 100% property tax exemption for solar installations for 25 years. This is an exceptional benefit that protects homeowners from tax increases related to their solar investment.
Maui County Property Tax Considerations
Maui County does not currently offer a statewide mandated property tax exemption for solar installations. However, the actual impact on property taxes is typically minimal, and the value solar adds to your home when you sell far outweighs any modest property tax increase.
Many Maui homeowners find that even without a formal tax exemption, the financial benefits of solar—including energy savings, state tax credits, and increased home value—make it a worthwhile investment regardless of property tax implications.
ProVision Solar can provide guidance on how solar might affect your specific property tax situation and help you understand the complete financial picture.
Net Energy Metering: Ongoing Value from Your Solar System
While not technically an “incentive,” net energy metering (NEM) provides ongoing financial value for Maui solar customers and deserves mention.
How Net Energy Metering Works in Maui
When your solar system produces more electricity than your home uses, the excess energy is exported to the Hawaiian Electric grid. Under net energy metering programs, you receive credits on your electric bill for this exported energy.
There are different NEM programs available depending on when you installed your system and your specific situation:
Smart Export allows you to export excess solar energy to the grid and receive credits at a favorable rate. This is one of the current programs available for new solar customers in Maui.
Customer Self-Supply is designed for customers who don’t export energy to the grid but may still need grid connection for backup power.
Different programs have different benefits and requirements, and ProVision Solar will help you determine which program makes the most sense for your situation during system design.
The Value of Grid Connection
Being connected to the grid provides several benefits beyond export credits:
You have backup power available when solar production is low, you can export excess energy rather than wasting it, you maintain normal electricity service during system maintenance, and you have flexibility as your energy needs change over time.
Grid connection combined with solar means you get the best of both worlds: clean, renewable energy from your panels most of the time, with the grid as a reliable backup.
Solar Financing: Making Incentives Work for Your Budget
Hawaii’s solar incentives significantly reduce your net cost, but you might still be wondering how to afford the upfront investment. That’s where solar financing comes in.
Sungage Solar Loans for Maui Homeowners
ProVision Solar partners with Sungage Financial to offer solar loans specifically designed for Hawaii homeowners. These loans make it possible to go solar with zero money down while still qualifying for all available incentives.
Here’s how it works:
You finance your solar system with no upfront payment. You claim the Hawaii state tax credit on your taxes, receiving $5,000 to $7,000 or more back. You use the tax credit refund to pay down your loan principal, reducing your monthly payments. Your monthly loan payment is often less than what you were paying for electricity.
The Financial Advantages of Solar Loans
Solar loans allow you to own your system immediately (not lease), which means you receive all tax credits and incentives. You start saving money from day one as your solar loan payment typically costs less than your previous electric bill. Once the loan is paid off, you enjoy free electricity for the remaining life of your system (typically 15-20+ years). Your home’s value increases, as you own the solar system outright.
ProVision Solar can walk you through financing options and help you understand your monthly payment compared to your current electric bill.
Combining Incentives: The Total Savings Picture
The real power comes from combining multiple incentives and benefits to maximize your solar savings in Maui.
Complete Incentive Stack Example
Let’s look at a comprehensive example for a typical 6 kW solar system in Maui:
- Base system cost: $21,000
- Hawaii State Tax Credit (35%): -$6,000
- Your net cost after tax credit: $15,000
Now let’s add the Tesla Powerwall 3 with BYOD Plus:
- Powerwall 3 cost: $14,000
- BYOD Plus upfront incentive (5 kW commitment): -$2,000
- Powerwall net cost: $12,000
- Total system cost (solar + battery): $27,000
- Annual electric bill savings: ~$2,400 ($200/month)
- Annual BYOD Plus export credits: ~$624
- Total annual savings: ~$3,024
- Payback period: Approximately 7-8 years
After payback, you enjoy free electricity and ongoing BYOD Plus credits for the next 15-20+ years, resulting in total lifetime savings exceeding $50,000.
Additional Benefits Beyond Direct Incentives
While we’re focusing on financial incentives, it’s worth noting the additional benefits that add value to your solar investment:
Environmental Impact
Every kilowatt-hour your solar system produces reduces your carbon footprint and supports Hawaii’s goal of 100% renewable energy by 2045. This environmental benefit has real value, even if it’s not measured in dollars.
Energy Independence
Especially when paired with battery storage, solar gives you control over your energy supply and protection from future utility rate increases. Maui electricity rates have risen steadily over the years, and solar locks in your energy costs.
Increased Home Value
Studies show that homes with solar systems sell for more than comparable homes without solar. The exact increase varies, but solar is widely recognized as a valuable home improvement that appeals to buyers.
Protection from Power Outages
With a Tesla Powerwall 3, you have backup power during grid outages—a valuable benefit in Maui where storms or equipment failures can cause temporary power interruptions.
Important Considerations for Maui Homeowners
As you evaluate solar incentives, keep these points in mind:
Tax Liability Requirements
To benefit from the Hawaii state tax credit, you need sufficient state income tax liability. If you don’t owe enough taxes in one year to use the full credit, you can carry it forward, but it’s important to understand your tax situation.
ProVision Solar recommends consulting with your tax advisor or accountant to understand how the solar tax credit will work with your specific tax situation.
Timing Matters
Incentives can change over time. While Hawaii’s 35% state tax credit is currently strong, future legislative changes could modify the program. Going solar sooner rather than later ensures you lock in current incentive levels.
System Ownership Is Key
Only system owners receive tax credits and incentives. If you lease a solar system rather than purchasing it (either with cash or financing), you won’t qualify for the state tax credit. This is why ProVision Solar recommends purchasing over leasing for maximum financial benefit.
Professional Guidance Helps
Navigating solar incentives, tax credits, and program enrollment can be complex. ProVision Solar guides you through every step, helps you understand all available incentives, assists with tax credit documentation, handles BYOD Plus enrollment if you add battery storage, and ensures you maximize your financial benefits.
