Your Legal Right to Cancel a Lone Star Solar Contract in Texas
Texas SB 1036: The Law That Changed Everything
Texas passed Senate Bill 1036 in June 2025. The full name is the Residential Solar Retailer Regulatory Act. It took effect on September 1, 2025.
The law gives every Texas homeowner 5 business days to cancel a solar contract. You do not need a reason. There is no fee. It is your legal right.
Before this law, solar companies set their own cancellation rules. They buried exit terms deep in the contract. That is no longer allowed. The Texas Department of Licensing and Regulation, known as TDLR, now oversees solar sales in the state.
What the 5 Business Day Rule Means for You
The 5-day window starts on the later of two dates: when you signed the contract or when you got all required written disclosures, whichever came last.
If the company never gave you full written disclosures, the clock may not have started at all. That works in your favor.
Texas Attorney General data shows solar complaints rose from 154 in 2020 to 696 in 2024. That is a 350 percent jump. This is exactly why SB 1036 was written. For a full breakdown of how this law applies to your specific situation, see our Texas solar cancellation laws guide.
Door to Door Sales Get Extra Protection
Did a salesperson come to your home without an invite? Federal FTC rules also apply to you. Those rules give you a separate 3 business day right to cancel. You cannot sign away these rights, even if a document says you did.
When the Cancellation Window May Stay Open Longer
SB 1036 says the 5 day period does not start until you get all required disclosures. Those disclosures must cover total cost, loan terms, expected savings, and ownership details in plain language.
If the company skipped any of these, your window to cancel may still be open today.
Step by Step: How to Cancel Your Lone Star Solar Contract
Step 1: Read the Cancellation Clause in Your Contract
Pull out your signed agreement. Find sections labeled Cancellation, Right of Rescission, or Consumer Rights. Note the deadline, required notice method, and the address to send it to. This tells you exactly what the company requires. If you are unsure what type of agreement you signed a loan, lease, or PPA review the Solar Contract Type guide before proceeding, as each type has different cancellation rules.
Step 2: Collect Your Documents
- Signed solar contract and all attachments
- Any written or emailed promises from the salesperson
- Your loan or financing agreement
- Permit applications or approval emails
- All texts or emails from Lone Star Solar
- Photos of any equipment at your property
Step 3: Write a Clear Cancellation Notice
Your notice must be in writing. Include your name, home address, the date you signed, and a direct statement that you are canceling. Keep it short. Do not apologize or explain at length. Send it to every address listed in the contract.
Step 4: Send It the Right Way
Use certified mail with a return receipt. This creates a legal record with a timestamp. Email is fine as a backup. But the physical mailed copy is what protects you if there is a dispute later.
Step 5: Notify Your Lender
The solar contract and the loan are two separate agreements. Canceling one does not cancel the other. Contact your lender the same day, in writing, and tell them you have canceled the solar contract.
Step 6: Keep All Records
Save your certified mail receipt, the delivery confirmation, and every reply you get. If this becomes a legal dispute, that paper trail is your strongest tool.

What If the Cancellation Period Has Already Passed?
You May Still Have a Path Out
Missing the 5 day deadline is not the end. Texas law gives you other tools, especially if the company said things that were not true.
The Texas Deceptive Trade Practices Act
The Texas DTPA lets you seek damages when a company makes false or misleading claims to get you to sign. Common complaints against Lone Star Solar include inflated savings estimates, false claims about the federal tax credit, and verbal promises that never made it into the contract.
One thing worth knowing: the 30 percent federal solar tax credit expired on December 31, 2025. If a salesperson told you this credit was available but misrepresented how it works or who qualifies, that may support a misrepresentation claim.
Evidence That Can Support Your Claim
- Recorded calls or voicemails from the salesperson
- Written estimates showing projected savings
- Text messages referencing verbal promises
- Marketing materials with specific bill reduction numbers
- Any document referencing government rebates not listed in your contract
What the Attorney General Investigation Means for You
In April 2026, the Texas AG sent formal Civil Investigative Demands to Lone Star Solar Services LLC and three other companies. This is a legal process. It does not give you an automatic refund. But it does give you leverage. It also shows that regulators already believe something went wrong.
Solar Contract Cancellation Costs in Texas
What you may owe depends on when you cancel and how far along the project is.
| Fee Type | Estimated Amount | When It Applies |
| Admin or cancellation fee | $0 to $500 | Early cancellation after the window |
| Permit filing fees | $200 to $800 | After permits are submitted |
| Restocking or equipment fee | $1,000 to $3,500 | Equipment already ordered |

| Loan early exit fee | Varies by lender | Funds already sent to company |
What Happens to Your Solar Loan?
The Contract and the Loan Are Two Separate Things
Most Lone Star Solar deals involve a third party lender. Common lenders include GreenSky, Mosaic, and Sunlight Financial. Canceling the install contract does not cancel the loan on its own.
What to Tell Your Lender
Send a written notice to your lender. Say that you have canceled the solar contract. Ask them to stop any payment to Lone Star Solar. If they already sent the money, ask what the refund process is for a canceled project.
What About Your Credit Score?
If the dispute drags on and your lender reports a missed payment, your credit score could drop. Stay current on loan payments while you sort out the dispute. Do not assume the loan goes away on its own.
What If Lone Star Solar Refuses to Cancel?
Start With a Written Demand
Before filing any complaints, send a formal written demand to company management. Not just the salesperson. Reference your cancellation date, your rights under SB 1036, and give them 10 business days to respond.
File a Complaint With TDLR
TDLR has accepted consumer complaints against solar retailers since September 1, 2025. Go to tdlr.texas.gov to file online. Attach your contract, your cancellation notice, and all written communication with the company.
File a Complaint With the Texas Attorney General
The AG is already looking into Lone Star Solar. Adding your complaint to the record is quick and free. Go to texasattorneygeneral.gov and file through the online form. Your report adds to the broader investigation.
Report the Loan Issue to the CFPB
If your dispute involves financing, the Consumer Financial Protection Bureau handles solar loan complaints. Go to consumerfinance.gov and select the loan under the product type.
File With the Better Business Bureau
BBB complaints are public. They can pressure companies that care about their public profile. While the BBB cannot force action, a pattern of complaints helps any legal case you build later.
When to Call a Texas Solar Contract Lawyer
Signs You Need Legal Help
- You are past the 5 day window and the company will not cancel
- Your loan has already been paid out to the company
- Work has started or the system is fully installed
- The salesperson made specific promises that are not in the contract
- The company is sending collection notices or reporting you to a credit bureau
What a Lawyer Can Do for You
A consumer rights attorney can send a formal demand letter. They can file a DTPA lawsuit, negotiate a rescission, and in many cases recover attorney fees under Texas law. Most solar contract lawyers offer a free first call.
When You May Not Need a Lawyer
If you are still within the 5 day window and the company is working with you, legal help is likely not needed. Follow the steps in this guide, keep your records, and the process should go smoothly.
Frequently Asked Questions
How long do I have to cancel a Lone Star Solar contract in Texas?
You have 5 business days from the date you signed or the date you got your required disclosures, whichever was later. This right comes from Texas SB 1036 and applies to contracts signed on or after September 1, 2025.
Can I cancel after the 5 day window has closed?
Yes, but it takes more work. You can file a DTPA claim for misrepresentation, submit a TDLR complaint, or raise a breach of contract claim. Document every misleading statement the salesperson made.
Does canceling the solar contract cancel my loan?
No. You must notify your lender separately and in writing. The loan and the install contract are two different legal agreements.
What if the salesperson made promises not in the contract?
Verbal promises that differ from the written contract are hard to enforce on their own. But if those promises pushed you to sign, you may have a misrepresentation claim under the Texas DTPA.
Can I cancel after the install has started?
Yes, but expect to negotiate. You may owe for work already done. If the project started because of misleading claims, a lawyer can help reduce what you owe.
Your Next Step Depends on Your Situation
If you signed within the last 5 business days, send your cancellation notice right away. This is usually the easiest time to cancel. If the deadline has passed, do not assume you are out of options. Misleading sales claims, financing issues, or contract problems may still give you grounds to challenge the agreement.
If financing is involved, contact the lender in writing as soon as possible. The loan and the solar contract are often separate agreements. If installation has started or the company is not cooperating, keep records of every email, text, estimate, and contract.
Most importantly, act quickly and document everything. The sooner you address the issue, the more options you are likely to have.
