Solar Contract Red Flags: The 20-Year Trap on Your Roof

A homeowner in California tried to sell her house. The buyer had a 785 credit score. The sale fell apart anyway, because the solar lease company wouldn't transfer the contract unless the buyer either added a co-applicant, paid out the remaining 24 years in cash, or accepted terms the buyer's lender wouldn't underwrite.

She didn't sign a 24-year obligation knowing it could break a future home sale. The clause was in her contract. The door-to-door rep didn't read it to her.

Solar contract red flags aren't subtle. They're 25-year terms, escalating payments, liens on the roof, transfer requirements that effectively give the solar company veto power over who buys your house. Same playbook applies to high-pressure HVAC service plans, water-treatment contracts, and pest-control auto-renewals. This is what to look for, and what your three-day cancellation window actually covers.

TL;DR

• Most solar leases and PPAs run 20 to 25 years and include an escalator clause that raises your payment 1% to 5% every year.
• The solar company files a UCC-1 fixture lien when you sign. It clouds your title and can block a refinance or sale.
• Transferring the contract to a buyer requires the buyer to qualify with the solar company's lender. Many don't.
• The FTC's Cooling-Off Rule gives you three business days to cancel a door-to-door sale of $25 or more. The seller has to tell you about it in writing at signing.
• HVAC service plans, water softeners, and pest-control contracts use most of the same clauses. The fixes below apply to all of them.

1. The escalator clause that doubles your payment

Customer agrees to pay the Producer Price for all Solar Energy
delivered hereunder. The Producer Price shall be $0.18 per kWh in
Year 1 and shall increase by 2.9% on each anniversary of the
Service Commencement Date for the duration of the Term.

High risk. The number that matters here is the escalator percentage, and it compounds.

A $150 monthly payment with a 2.9% annual escalator becomes $293 per month by year 25. A 3.9% escalator gets to $389. Solar reps quote you the year-one number. The contract quotes you the escalator. Multiply forward 25 years before you sign anything.

The honest version: a flat rate, or an escalator capped at 1% to 1.5%. The dishonest version: 3% to 5% compounded over 25 years, often paired with a "comparison to projected utility rate increases" pitch that assumes utility rates rise at the same pace. They usually don't.

What to do: ask the rep to show you the year-25 monthly payment in writing. If they won't put it on the contract, walk.

2. The UCC-1 fixture lien on your house

Under the Uniform Commercial Code, a UCC-1 financing statement is a public filing that creates a security interest in property. When the property is "affixed" to your house, which is what solar panels are, the filing is called a fixture filing, and it goes in the county real-estate records right next to your mortgage.

High risk. Your contract probably authorizes it in language like this:

Customer hereby grants Provider a security interest in the System
and authorizes Provider to file UCC-1 financing statements,
including fixture filings, in the public records of the
jurisdiction in which the Premises are located.

The solar company will tell you the lien is on the panels, not on the house. Technically true. Practically, when a title company runs a search before closing on your home sale, the fixture filing shows up. Lenders ask about it. Buyers' attorneys ask about it. Some require the filing to be released before they'll fund the loan. Releasing the filing means paying off the system in full or convincing the solar company to subordinate, neither of which the company has any reason to do quickly.

What to do: before signing, ask whether the company will file a UCC-1 fixture filing. If yes, ask what their process is to release or subordinate the lien for a future sale, and how long it takes. Get the answer in writing.

3. The transfer trap

Upon any transfer of the Premises, Customer shall require the
transferee to assume all of Customer's obligations under this
Agreement, subject to Provider's review and approval of the
transferee's creditworthiness and execution of an Assumption
Agreement satisfactory to Provider.

High risk. This is the clause that breaks home sales.

When you sell your house, the buyer must apply to the solar company, qualify under the company's credit standards, and sign an assumption agreement. The buyer's mortgage lender then has to factor the remaining lease payments into the buyer's debt-to-income calculation.

Three things go wrong, repeatedly:

• The buyer doesn't qualify under the solar company's standards even with strong credit.
• The buyer's mortgage lender treats the long-term lease as a property encumbrance and asks for it to be cleared at closing.
• The buyer simply refuses to take on the lease, and asks you to buy it out as a price-reduction credit.

The third option is what most homeowners end up doing, often paying tens of thousands at closing to escape the contract.

What to do: read the transfer clause before signing. Look for two things. The buyer-qualification standard, and any buyout option that lets you settle the contract for a defined dollar amount instead of "the present value of all remaining payments at the company's discount rate."

4. The 25-year term, and what happens if the company is gone

Solar leases and power purchase agreements typically run 20 to 25 years. The HVAC service plan or water-treatment contract you signed at the same kitchen table runs 5 to 10. The pest-control auto-renewal runs forever.

Medium risk. The length itself is the obligation. The company you're signing with may not exist in year 18.

When SunStrong, a major leaseholder, slid into bankruptcy in 2024, homeowners woke up with billing chaos, ambiguous warranty obligations, and unclear paths to remove panels they no longer trusted. SunRun and others have continued operating. Tesla Solar's lease portfolio has been a steady source of complaints about transfer denials and unresponsive support.

What to do: search the company name plus "bankruptcy," "lawsuit," and "BBB complaints" before you sign. A clean name today is not the same as a company that will exist in 2046, but a public bankruptcy two years ago is a flashing light right now.

5. The 3-day window the seller has to tell you about

Under the FTC's Cooling-Off Rule (16 CFR Part 429), you have three business days to cancel any sale of $25 or more that was made at your home or anywhere other than the seller's place of business. Door-to-door solar pitches qualify. So do home-show sales of HVAC and water systems.

The rule requires the seller to:

• Tell you about your right to cancel orally at the time of sale.
• Give you two copies of a cancellation form, dated correctly.
• Give you a copy of the contract that explains the cancellation right in plain language.

If they did not do all three, the three-day clock may not have started. Many state laws extend the window further when notice was deficient.

What to do: count three business days from the date you signed. Saturday counts. Sundays and federal holidays don't. To cancel, sign and date the cancellation form, mail it to the address provided, and make sure the envelope is postmarked before midnight on day three. Send it certified mail with return receipt. Keep the receipt and a copy of the form.

If you no longer have the cancellation form, you can write your own letter saying "I am canceling the contract dated [date] under the FTC's Cooling-Off Rule." The right exists whether the form is in your hand or not.

6. The HVAC, pest control, and water-treatment versions

Same playbook, smaller numbers, shorter terms.

HVAC service plans that come with a new installation often include 10-year auto-renewing service obligations with cancellation fees that reset each renewal. The clause that locks you in is usually an auto-renewal with a notice window of 30 to 90 days.

Water softener and water treatment rentals are leases. Same UCC-1 filing logic. Some come with a personal guarantee on top of the equipment lease.

Pest control contracts often run on perpetual auto-renewal with cancellation fees of $200 to $400. The fee is enforceable in most states if it was disclosed at signing.

The clause structure is identical: long term, hard-to-cancel renewal, financial penalty for leaving early, security interest in the equipment. If you read the solar contract carefully and find these patterns, you'll spot them in the HVAC or pest-control contract on the next page.

7. Before you sign, after you sign

Before you sign, run these five questions:

• What is the year-one rate, and what is the year-25 rate?
• Will the company file a UCC-1 or fixture filing? What's the release process for a future sale?
• What does the transfer clause require of a future buyer?
• Is there a defined buyout amount, or only an undefined "present value" calculation?
• What is the cancellation window and how do I exercise it?

If you've already signed and you're inside the three-day window, send the cancellation letter today. If you're outside the window, the lever moves to your state attorney general's consumer-protection division. Most states have one and they handle solar complaints. Add the CFPB if there's a financing component, plus a written demand to the company that quotes the specific clauses they're not honoring.

The shape underneath

A solar contract is the canonical version of the long obligation with a quiet escape shape: a 25-year commitment that the seller will close in 25 minutes, with a three-day window most homeowners don't know exists. The same structure shows up in equipment leases, service plans, and franchise agreements.
