Buy vs. Lease Solar in Hawaii: What Makes Sense in 2026?
With the federal credit gone for homeowners, does buying a system still beat leasing? We run the numbers for a typical Maui home paying 46¢–48¢ per kWh.

In Hawaii, the math for solar is unique because you pay the highest electricity rates in the nation — Maui residents pay 46¢–48¢ per kWh as of early 2026, with Big Island residents exceeding 50¢. While losing the 30% federal credit for purchases hurts, Hawaii's own state incentives and sky-high utility costs keep solar a no-brainer, even if you have to change how you pay for it.
Here is how the comparison looks for a typical Hawaii home in February 2026.
The Cost Breakdown: 8.6 kW System + Battery
Estimated system cost before incentives: $28,000.

Why the Lease Looks "Better" in 2026
In 2024, buying was the clear winner. In 2026, the gap has narrowed because of three factors:
**The Federal Gap:** On a $28,000 system, a bank can claim an $8,400 federal credit that you cannot. They use that money to lower your monthly lease payment to be significantly less than a standard MECO bill — which could run $350-$500 per month for the same usage at today's 46¢–48¢ per kWh rates.
**State Credit Logic:** Hawaii's 35% state tax credit is great, but it is capped at $5,000. It doesn't fully make up for the loss of the 30% federal credit ($8,400+).
**BYOD Plus Incentives:** HECO's Bring Your Own Device Plus (BYOD+) program offers upfront cash — up to $400 per kW — for batteries. If you lease, the leasing company often keeps this incentive but uses it to further lower your monthly rate.
The Wealth Trade-Off
While the lease is cheaper monthly than a utility bill, you are essentially renting your roof to a bank. The real question is whether you value ownership or convenience.
**The Buyer's Benefit:** You own a $28,000 asset that is proven to increase Hawaii home values by an average of $34,000 or more. After your system is paid off, your electricity is essentially free for the remaining 15-20 years of panel life. Over 25 years, a purchased system can save a Hawaii homeowner $80,000 or more compared to staying on the grid.
**The Leaser's Benefit:** You get immediate day-one savings without spending your savings, and the bank handles the technology. If a battery dies in year 12, the bank pays for the $10,000 replacement — not you. There is no permitting headache, no maintenance scheduling, and no worrying about inverter warranties.
Legislation to Watch: Senate Bill 2888
Keep an eye on Senate Bill 2888, introduced in late January 2026. It proposes increasing the Hawaii state solar credit from 35% to 45% to offset the loss of the federal credit. If this passes, buying outright would likely become the superior financial choice again — potentially bringing the net cost of a $28,000 system down to around $15,400.
One Key Question to Ask Yourself
Do you currently have a high enough tax liability in Hawaii to use the full $5,000 state credit in a single year? If yes, buying still makes strong financial sense despite losing the federal credit. If not, a lease or PPA lets you start saving from day one without needing to front any capital.
