The short answer

You can cancel a Texas home solar purchase or lease, without penalty or further obligation, by sending written notice on or before the fifth business day after you sign. That's Occupations Code 1806.156, in force since September 1, 2025. It applies even if the panels are already on your roof: TDLR's rules require the company to arrange removal and refund what you paid.

Send the notice to the address or email in your contract, in a way you can prove, and send a copy to your lender if there's a loan.

How to count the five days

Day one is the first business day after the day you sign. Business days leave out Saturdays, Sundays and these 15 legal holidays from Texas Government Code 662.021:

National holidays
  • New Year's Day, January 1
  • Martin Luther King Jr. Day, third Monday in January
  • Presidents' Day, third Monday in February
  • Memorial Day, last Monday in May
  • Independence Day, July 4
  • Labor Day, first Monday in September
  • Veterans Day, November 11
  • Thanksgiving, fourth Thursday in November
  • Christmas Day, December 25
Texas holidays
  • Confederate Heroes Day, January 19
  • Texas Independence Day, March 2
  • San Jacinto Day, April 21
  • Emancipation Day, June 19
  • Lyndon Baines Johnson Day, August 27
  • The Friday after Thanksgiving

Christmas Eve and December 26 are Texas state holidays, but not legal holidays, so they count as business days. Sign on Wednesday, December 23, 2026, and your last day is Thursday, December 31.

How to cancel, step by step

  1. Find the date and address

    Your contract must state the last calendar date to cancel and a mailing or email address for the notice. TDLR's rules require the cancellation statement in bold capital letters, 14-point or larger.

  2. Write the notice

    Keep it short and in writing; a phone call isn't enough. Use the sample below.

  3. Send it so you can prove it

    Use the method your contract gives, before the deadline. Email gives you a timestamp; certified mail with a return receipt gives you proof of mailing. If the contract allows only mail, TDLR's rule says the notice counts on the day you mail it. If the contract has no address, any reasonable written method works.

  4. Cancel the loan too

    If the company arranged or referred your lender, the contract must require that lender to cancel the loan when you cancel. Send the lender a copy of your notice.

  5. Get your money back

    When you cancel on time, TDLR's rules require the company to process the cancellation, arrange removal of anything already installed and refund what you paid.

A sample cancellation notice

Notice of cancellation

Today's date

To: company name, and the address or email from your contract

I am canceling my contract for the purchase / lease of a residential solar energy system, signed on date, for the home at address. Contract or account number: number.

I am canceling under Texas Occupations Code Section 1806.156. Please confirm the cancellation in writing, refund any money I paid, and cancel any related loan.

Keep a copy of the notice and your proof of sending. If everyone who signed the contract can sign the notice, have them do it.

Other cancellation rights that may also apply

The Texas solar law isn't the only one. Depending on where and how you signed, these can also apply, each with its own rules:

Occupations Code 1806.156

Texas solar law: 5 business days

Any home solar purchase or lease signed since September 1, 2025. Saturdays, Sundays and the 15 legal holidays don't count. Cancel in writing, without penalty or further obligation.

This is the longest window for most home solar deals.

Business & Commerce Code ch. 601

Texas home solicitation law: 3 business days

Applies when a seller solicits you and you agree somewhere other than its place of business, such as your home, for more than $25. You can cancel until midnight of the third business day after you sign.

The seller must tell you about this right out loud, refund you within 10 business days of your notice, and can't sell your loan note to a finance company before midnight of the fifth business day. Breaking those rules makes the contract void.

16 CFR part 429

FTC Cooling-Off Rule: 3 business days

Federal rule for sales of $25 or more made at your home. Business days here exclude only Sundays and federal holidays.

It doesn't apply when the federal Truth in Lending right below applies.

12 CFR 1026.23

Truth in Lending: 3 business days for a loan on your home

If a loan puts a security interest on your main home (other than a mortgage to buy it), you can rescind the loan until midnight of the third business day after signing, getting the rescission notice or getting all required disclosures, whichever is last.

If the lender never gave the notice or disclosures, the right can last up to three years.

If the five days have passed

There's no automatic right to cancel after the window closes. What's left depends on what the seller did:

  • The seller broke the solar law or TDLR's rules. Examples: an unregistered seller after September 1, 2026, false or misleading claims, a claimed link to your utility or the government, or missing contract terms. File a complaint with TDLR. After notice and a hearing, TDLR can order the contract canceled and refund what you paid, and if the company arranged the loan, the company must pay off its balance.
  • The seller skipped the home solicitation rules. Under Business & Commerce Code chapter 601, a contract is void if a seller who sold to you at home broke certain rules, such as not telling you about your right to cancel.
  • Your loan is secured by your home and you never got the rescission notice. The federal right to rescind can last up to three years.
  • You signed before September 1, 2025. The Texas solar law and TDLR's rules don't cover those contracts. The other rights above, and your contract's own terms, still can.

For these, a consumer attorney can tell you what applies to your contract. Our guide to checking a Texas solar company shows how to confirm a registration and what the contract must include.

Common questions

How long do you have to cancel a solar contract in Texas?

Five business days. Texas Occupations Code 1806.156 lets you cancel a home solar purchase or lease, without penalty or further obligation, by sending written notice on or before the fifth business day after you sign. It covers contracts signed since September 1, 2025.

Do weekends and holidays count toward the 5 days?

No. Saturdays, Sundays and the 15 legal holidays in Texas Government Code 662.021 don't count. Christmas Eve and December 26 are state holidays but not legal holidays, so they do count.

How do I cancel a solar contract in Texas?

Send a written notice to the mailing address or email address in your contract by the last date printed in it, in a way you can prove, such as email or certified mail. If the contract has no address, any reasonable written method works. Send a copy to your lender if there's a loan.

Does canceling the solar contract cancel my solar loan?

If the solar company arranged or referred your lender, yes: the contract must require that lender to cancel the loan when you cancel. For a loan you found yourself, check its own terms; if it's secured by your home, federal Truth in Lending rules may give you a separate three-business-day right to rescind it.

Can I cancel a solar contract after 5 days in Texas?

Not automatically. If the seller broke the Texas solar law or TDLR's rules, you can complain to TDLR, which can order the contract canceled and your money refunded after notice and a hearing. Other laws, such as the home solicitation law, can also apply.

What if the panels are already installed?

You can still cancel within the five business days. When you cancel on time, TDLR's rules require the company to process the cancellation, arrange removal of any installed equipment and refund the money you paid.

The deadline tool counts days the way Occupations Code 1806.156 defines them; the date printed in your contract is the one the seller has committed to. Not legal advice.
