Financing

5 questions to ask before signing a solar lease or PPA

Published Updated October 30, 2026 4 min read

A low monthly payment can hide a much higher total cost. Here is what to ask before you sign any solar financing in Hawaii.

The monthly number looks great. Then you read the fine print.

Solar leases, power purchase agreements (PPAs) and long loans can all lower what you pay upfront. That is real value. But the contract details decide whether you come out ahead, and those details are easy to miss when someone is showing you a low monthly payment.

Before you sign anything, ask these five questions.

1. Does the payment go up each year?

Many leases and PPAs include a yearly increase, often called an escalator. A small annual bump does not sound like much. Over 20 years, it adds up.

Ask for the exact increase in writing, and ask what your payment will be in year 10 and year 20. If the answer is vague, that is a warning sign.

2. How long is the contract?

Many solar contracts run 20 years or more. That is a long commitment, longer than most people stay in one home.

Make sure the term fits your plans. If you might move in 5 years, a 25-year contract becomes a problem for whoever buys your house.

3. What happens if I sell my home?

With a lease or PPA, the buyer usually has to agree to take over the contract. Some buyers are happy to. Others are not, and that can slow down a sale or force you to buy the system out.

Ask exactly how a transfer works, what it costs and what happens if the buyer says no.

4. What happens if the company goes out of business?

This is not a hypothetical question in Hawaii. Thousands of homeowners have solar systems whose installer closed or left the islands.

Ask who owns your contract if the company closes, who will service your system and who handles warranty claims. If no one can answer clearly, keep asking. SolarServe by Independent Energy Hawaii services systems from any installer, including orphaned ones.

5. Can I buy the system out early?

Plans change. Ask whether you can buy the system outright before the contract ends, when you can do it and how the price is calculated. Get it in writing.

How the total cost compares

The best way to compare financing is the total you will pay, not just the monthly payment. Here is an illustrative HSFCU example:

Illustrative HSFCU loanAssumption
Amount financed$57,000
Total term8 years, including 18 months with no payments
APR0% for 18 months, then 7.7%
Repayment78 payments of about $931
Total paidAbout $72,600, excluding fees

Illustration only, not a lender quote. Confirm the repayment schedule and fees with HSFCU. Subject to credit approval; rates and terms may change.

Compare the total paid, fees and repayment timing in actual lender disclosures. A shorter loan can reduce total interest, depending on its APR and fees.

Key takeaways

  • Ask about yearly increases, contract length, home sales, company closures and buyout terms before you sign.

  • Compare total cost, not monthly payment.

  • Compare the total paid, fees and repayment timing in actual lender disclosures. A shorter loan can reduce total interest, depending on its APR and fees.

Participate Energy is an upfront prepaid lease, not a zero-down monthly lease. Ownership, maintenance, transfer and buyout terms depend on the agreement. IEH does not offer PPAs.
