Zero Down Solar in Hawaii: How Power Purchase Agreements Work

Federal tax credit disclaimer (updated October 30, 2026): The 30% federal Residential Clean Energy Credit is no longer valid for new residential solar or battery installations after December 31, 2025. Any references to that credit or savings based on it below are historical, not a current offer. Separate business or third-party-owned system incentives have different rules. Confirm your eligibility with a qualified tax professional.

A Power Purchase Agreement (PPA) lets you go solar without paying anything upfront. Instead of buying panels and a battery outright, you agree to purchase the electricity your system produces at a fixed rate that is lower than your current Hawaiian Electric rate. The solar provider installs, owns, and maintains the system; you get immediate savings and a predictable monthly cost without the upfront investment. For Hawaii homeowners facing some of the highest electricity rates in the country, a PPA is a practical way to access solar and battery storage without financing or purchasing equipment.

Why choose a PPA instead of buying a system

A PPA delivers many of the same benefits as owning a system, lower bills, renewable power, and more predictable costs, without the large upfront investment or long-term maintenance responsibility.

Zero upfront cost

The provider covers all installation and hardware costs. There is no loan to qualify for based on the system price and no cash outlay at signing, which makes solar accessible to homeowners who would rather not tie up capital in equipment they would otherwise need to finance or pay for outright.

Immediate savings

Most Hawaii homeowners on a PPA save 20 to 40% on electricity from day one. A household with a $500 monthly HECO bill might pay around $300 under a PPA, saving roughly $200 a month, about $2,400 a year, and an estimated $60,000 over 25 years.

Predictable costs

A PPA locks in a stable per-kilowatt-hour rate for up to 25 years, insulating you from Hawaiian Electric’s typical annual rate increases of 5 to 10%. Knowing your energy cost in advance makes long-term budgeting easier and removes exposure to future rate volatility.

Tax credits handled for you

Because the provider owns the system, any eligible business tax incentives are handled by the provider and may be reflected in your agreement pricing. These are separate from the expired homeowner residential credit. Ask the provider to confirm current eligibility and how any incentives affect your rate; do not assume a fixed federal credit applies.

Full-service maintenance

Since the provider owns the equipment, they are responsible for performance monitoring, repairs, and warranty coverage for the full term of the agreement. You get guaranteed uptime without arranging your own maintenance and service calls.

How our PPA partner structures the agreement

Our PPA partner, GoodLeap, is a national clean energy financing company that specializes in accessible home energy upgrades. Through GoodLeap, homeowners get $0-down installation, a fixed rate below utility pricing, and full system ownership, maintenance, and monitoring for 25 years.

Ownership

GoodLeap owns the system and is responsible for installation, monitoring, and any necessary repairs. You simply purchase the electricity it produces.

Payments

Your monthly payment is based on the electricity the system actually generates, measured in kilowatt-hours. We offer a fixed-rate plan that holds steady over the full 25-year term, rather than an escalating-rate structure that increases each year, which some other providers use.

End-of-term options

When the agreement ends after 25 years, you have three choices:

1. Renew the agreement to continue your current savings.
2. Purchase the system outright at fair market value, typically 10 to 20% of its original cost.
3. Have the system removed at no cost to you.

That flexibility means your solar arrangement can adapt as your home and energy needs change, rather than locking you into one outcome decades in advance.

PPA versus ownership: a quick comparison

Common questions about PPAs

Selling your home with a PPA in place is straightforward in most cases: buyers generally see existing solar as a selling point, and the agreement can be transferred to the new homeowner. If your energy use grows, most PPA providers allow system expansion to add capacity rather than requiring a whole new agreement. And qualifying is typically based on roof suitability and credit rather than income, so a site visit is usually enough to confirm eligibility.

Next steps

If a PPA sounds like the right fit for your home, the process is simple:

1. Schedule a free consultation with Independent Energy Hawaii to evaluate your solar potential and savings.
2. Design your custom system with our team, including storage and rate options.
3. Install and start saving. The process typically takes 4 to 8 weeks from approval to activation.
