You can cancel a Sunlux solar contract within 3 business days of signing under the FTC Cooling-Off Rule (16 CFR Part 429). California homeowners get additional protection under Civil Code §1689.6. Texas homeowners have rights under the Business & Commerce Code Chapter 601 and the DTPA. After the cooling-off window closes, you can still exit through misrepresentation, breach of contract, or TILA violations.
What Kind of Company Is Sunlux, and Why Are People Trying to Leave?
Sunlux Energy is a California-based solar installer founded in 2015, operating primarily in Southern California (Orange County, the Inland Empire, and San Diego) and Central Texas. The company advertises over 6,000 installations and sells directly to homeowners through a sales team model.
Most Sunlux customers do not sign a lease. Instead, they finance through third-party lenders, commonly Mosaic, Goodleap, Sunlight Financial, or Greensky, on loan terms running 12 to 25 years.
This distinction matters enormously when you try to exit, because your cancellation rights against Sunlux and your rights against the lender are governed by completely separate contracts and separate laws.
What Sunlux Customers Are Complaining About
BBB filings for both Sunlux Energy (Corona, CA, license #1008374) and SunLux Energy (Rancho Cucamonga, CA) paint a consistent picture. The complaints cluster around four recurring issues:
Sunlux complaints often involve systems producing far less energy than promised, leaving homeowners with large utility bills despite expensive installations. Other customers report roof leaks, broken tiles, and interior damage that went unresolved for years.
Several reviews also describe poor post-installation support, including unanswered service requests and nonworking systems that stayed offline for months. Some homeowners said monitoring and Wi-Fi setup were never activated, making it impossible to detect underperformance until significant financial losses had already occurred.
These are not minor service complaints. Under California and Texas consumer protection law, each of these patterns can constitute grounds for legal action.
Your 3-Day Right to Cancel a Sunlux Solar Contract
The fastest and cleanest exit is to act immediately after signing. Both federal and state law protect you here.
Under the FTC Cooling-Off Rule (16 CFR Part 429), any contract signed at your home, including a Sunlux sales presentation at your kitchen table, gives you three business days to cancel without penalty or explanation.
The seller was legally required to give you two printed cancellation forms at the time of signing. If they did not, the three-day clock likely never started. That means your window to cancel may still be open.
California-Specific Rights
California’s Home Solicitation Sales Act (Civil Code §1689.6) mirrors the federal rule but adds critical protections. Under Civil Code §1689.7, Sunlux cannot begin any installation work until the three-day period has expired. If they did start work before that window closed, they violated state law — giving you an additional legal lever.
California also grants senior citizens (65+) a five-day window rather than three days under AB 2471.
If Sunlux failed to provide the required “Three-Day Right to Cancel” notice on the face of the contract, California courts have interpreted §1689.7(g) strictly: the cancellation right extends indefinitely until the required notice is properly delivered.
One appellate court described this plainly. The law “technically extends indefinitely” the buyer’s right to cancel when the seller hasn’t complied. That is not a technicality. It is a real, enforceable right.
California homeowners can also file complaints with the Contractors State License Board (CSLB) at www.cslb.ca.gov. Sunlux holds California license #1008374 (expiration 10/31/2025 per BBB records — worth verifying for currency). A CSLB complaint for a contractor with a lapsed or deficient license creates significant legal leverage in contract disputes.
Texas-Specific Rights
Sunlux operates in Central Texas. Texas homeowners have their own independent set of rights.
Under Texas Business & Commerce Code Chapter 601, Section 601.052, door-to-door solar sales carry a three-business-day cancellation right. Section 601.053 requires the seller to provide a written cancellation notice, and failure to do so extends your cancellation window.
Beyond the cooling-off rule, Texas is home to the Deceptive Trade Practices Act (DTPA), one of the strongest consumer protection statutes in the country. If a Sunlux salesperson made false promises about savings, energy offset, tax credits, or bill reduction that turned out to be untrue, that is a DTPA violation.
The Texas Attorney General’s office confirms: if you win and prove the defendant “knowingly” deceived you, you can recover up to three times your actual damages. Attorney’s fees under a winning DTPA claim are mandatory, not optional.
Starting September 1, 2026, the Texas Department of Licensing and Regulation (TDLR) now requires residential solar retailers and salespeople to register with the state. Contracts sold after this date without proper registration may be voidable.
How to Cancel Sunlux Solar Contract in the 3-Day Window
Do this in writing. Verbal cancellation means nothing and gives Sunlux room to dispute whether they received notice.
- Write a cancellation notice. State your name, address, the date you signed the contract, and that you are canceling under the FTC Cooling-Off Rule and (if applicable) California Civil Code §1689.6 or Texas Business & Commerce Code §601.052.
- Send it via certified mail with a return receipt requested. The postmark date is what the law looks at.
- Send a copy via email with delivery confirmation to create a parallel record.
- Keep both copies.
Sunlux has 10 days after cancellation to cancel any promissory notes or financing documents and refund your money. If a lien was placed on your home through a UCC-1 filing, that must also be removed.
Cancellation Before Installation
If panels have not yet been installed, you are in the strongest possible position. Even past the three-day window, some contracts include pre-installation cancellation clauses. Pull out both your Sunlux installation agreement and your loan agreement and look specifically for:
- Any pre-installation cancellation right
- Whether Sunlux began work before your three-day window expired (a violation of California law)
- The exact language around early termination fees
Can You Cancel a Sunlux Solar Contract After Installation?
Yes. The path is more complex, but it is real.
Post-installation cancellation requires identifying a legal basis. The most common and legally successful grounds are:
1. Misrepresentation
This is the leading cause of action in solar contract disputes nationwide. If a Sunlux salesperson told you that your system would cover 100% of your electricity use, reduce your bill by 50%, or pay for itself within a specific number of years, and none of that happened, you may have a misrepresentation claim.
What turns a broken promise into a legal case is documentation. Courts in California, Texas, and elsewhere have ruled that verbal promises made during a sales presentation count as evidence, especially when those promises appear in emails, proposal documents, or texts.
Production estimates built on unshaded satellite data that ignored visible trees or roof angles have been successfully challenged in court.
2. Breach of Contract
If Sunlux caused roof damage and refused to repair it, failed to honor its stated warranty, or left your system non-functional for extended periods, it may be in material breach.
Documented repair requests that went unanswered for months are exactly the kind of evidence that supports a breach claim. Save every email. Screenshot every service ticket. Log every phone call with a date and a description of what was said.
3. TILA Violations
The Truth in Lending Act (15 U.S.C. §1635) requires lenders to clearly disclose the annual percentage rate, total finance charge, and total cost of credit before you sign.
Many solar loan agreements originating through Goodleap, Mosaic, or Sunlight Financial contain disclosure failures. When a lender fails to provide required TILA disclosures, the borrower’s right to rescind the loan transaction can extend up to three years from the date of signing. This is a federal right.
4. FTC Holder Rule
If your Sunlux system was financed through a third-party lender and Sunlux made misrepresentations during the sale, the FTC Holder Rule allows you to bring those same claims directly against the lender.
This matters because Sunlux may be unresponsive, but the lender holding your $30,000 loan has far more to lose and is far more motivated to resolve a dispute.
Sunlux Solar Cancellation Policy: What the Contract Actually Says
Sunlux installation agreements are separate documents from your financing agreement. The installation contract governs what Sunlux installs, what warranties apply, and how disputes are handled with the installer. The loan agreement governs your monthly payment, interest rate, lien, and cancellation rights with the lender.
Most Sunlux customers do not realize these are two separate legal relationships until they try to cancel.
Key things to review in your Sunlux contract:
- The production guarantee language (or absence of it — Sunlux has told some customers their contract “does not guarantee production”)
- The warranty terms and the process for making warranty claims
- Whether an arbitration clause exists, and which state’s law governs disputes
- Whether a UCC-1 lien was filed against your property title
In your lender agreement, look for:
- The rescission window (typically 3 to 10 business days)
- The prepayment terms and whether early payoff comes with a penalty
- The lien removal process
If you cannot locate either document, request them in writing from both Sunlux and your lender. They are legally required to provide them.
Cost to Cancel Sunlux Solar Contract
Within the 3-day cooling-off window: Zero cost because federal and state law entitle you to a full refund.
Past the cooling-off window, before installation: Depends on your contract. Some agreements have no termination fee before installation begins. Others impose a processing or design fee, typically a few hundred dollars.
After installation, via legal action: Costs vary significantly based on your route:
- Attorney-led cancellation services often charge a flat fee or contingency arrangement
- Loan buyouts directly with the lender run approximately $10,000 to $40,000, depending on system size and years remaining
- Panel removal, if required after cancellation, typically costs $3,000 to $8,000
The cost of staying in a contract that costs you more than it saves.
Selling a Home with a Sunlux Solar Loan
If you financed your Sunlux system and are trying to sell your home, the UCC-1 lien your lender filed is now attached to your property title. Unlike a lease (which transfers to the buyer), a solar loan typically must be paid off at closing or assumed by the buyer.
Most buyers’ lenders will not approve a mortgage on a home with an existing solar lien without clear disclosure and resolution. This is a real, documented obstacle at real estate closings. If your Sunlux loan was misrepresented in terms of its impact on your ability to sell, that misrepresentation may be actionable.
Case Example: From $80,000 System to Legal Exit
One customer on Consumer Affairs described spending $80,000 on a Sunlux system that “never worked from the start.” When the company passed responsibility to Sunrun (a separate entity), this homeowner was caught between two companies, neither of which took ownership.
At Solar Equity Solutions, cases like this typically begin with a contract review that identifies whether the original sales representations are provable and whether the lender relationship allows for FTC Holder Rule claims against the financier.

Frequently Asked Questions
Can you cancel a Sunlux solar contract after installation?
Yes, but it requires a documentable legal basis. Misrepresentation, breach of contract, and TILA violations are the three most common grounds. A formal attorney review of your specific contract and loan agreement is the right first step.
What happens if Sunlux never gave me a cancellation notice when I signed?
Under California Civil Code §1689.7(g) and the FTC Cooling-Off Rule, the three-day window does not start until the required cancellation notice is properly delivered. If Sunlux skipped that step, your right to cancel may still be active.
How does the Texas DTPA apply to Sunlux solar contracts?
If a Sunlux salesperson made false or misleading representations about energy savings, tax credits, or bill reduction, and those representations influenced your decision to sign, Texas Business & Commerce Code §17.46 may apply. A successful DTPA claim can produce up to three times actual damages plus mandatory attorney’s fees. A 60-day written demand notice is required before filing suit.
Does a Sunlux solar loan affect selling my home?
Yes. Solar loans create a UCC-1 lien on your property title. Most buyers’ mortgage lenders require the lien to be resolved at or before closing. If this impact was never disclosed during the Sunlux sales process; that omission may constitute misrepresentation and create additional grounds for legal action.
Conclusion
The path to cancel a Sunlux solar contract depends almost entirely on timing, documentation, and which legal basis applies to your specific situation. The earlier you act, the more options you have. But even if years have passed, documented misrepresentation, breach of warranty, or TILA violations can still support a legal exit.
