Yes, you can sue a solar company when it fails to deliver what your contract promised, damages your property during installation, lies to close the sale, or refuses to honor a warranty. Those are four separate legal theories, and more than one often applies to the same dispute. What you can actually recover, and how long you have to file, depends on your contract, your state’s deadlines, and how carefully you’ve documented the problem.
Grounds That Support a Lawsuit
Not every complaint about a solar system is a lawsuit. Courts want to see a recognized legal claim, and solar disputes usually fall into one of four.
Breach of Contract
The contract is your measuring stick. If the company installed fewer panels than the agreement called for, substituted a different brand of equipment, missed the completion deadline, or delivered a system that falls short of a contractually guaranteed energy output, that’s breach of contract. This is the most straightforward claim because you don’t have to prove intent or carelessness. You only have to show what the written terms required and what the company actually did.
Negligence
Negligence covers careless installation or maintenance that damages your home. Improper roof penetrations that lead to water leaks are the classic example. Faulty wiring that creates fire hazards or damages your electrical system also qualifies. You don’t need to prove the company meant to cause harm, only that a competent installer would have avoided the problem.
Fraud and Misrepresentation
Fraud claims arise when a company knowingly makes false statements to get you to sign. In the solar industry, that tends to mean inflated projections of energy savings, misrepresentations about your eligibility for tax credits or rebates, and buried escalating payment schedules in financing agreements. The FTC has warned consumers about businesses “misrepresenting the cost of improvements, savings, and financing options” and has reminded companies not to “overpromise cost savings that might come through tax credits, rebates, or incentives.”1Federal Trade Commission. Don’t Waste Your Energy on a Solar Scam The IRS Taxpayer Advocate Service has also flagged solar salespeople who mislead buyers about the timeline and availability of tax credits to create false urgency.2Taxpayer Advocate Service. Don’t Get Taken in by Shady Solar Panel Scams
Fraud is harder to prove than breach of contract because you must show the company knew its statements were false when it made them. Vague sales talk (“you’ll love the savings”) won’t support a fraud claim. A written projection showing your electric bill dropping to zero when the company’s own data showed otherwise is a different story.
Breach of Warranty
Solar equipment and installation typically come with layered warranties. Panels often carry 25-year performance warranties from the manufacturer, inverters 10 to 15 years, and the installer may provide a separate workmanship warranty of 5 to 10 years covering the quality of the installation itself. If a covered component fails and the company refuses to repair or replace it under the warranty terms, that refusal is a breach of warranty you can sue over.
The Federal Warranty Law That Changes the Math
When a solar company gives you a written warranty on equipment or workmanship, the Magnuson-Moss Warranty Act adds a federal layer many homeowners don’t know about. It gives you the right to sue in any state court when a company fails to honor a written warranty, implied warranty, or service contract.3Office of the Law Revision Counsel. United States Code Title 15 – 2310 You aren’t limited to whatever remedy the warranty document describes. You can bring a full lawsuit for damages.
The statute also shifts fees. If you win, the court can order the solar company to pay your attorney’s fees and litigation costs on top of your damages.3Office of the Law Revision Counsel. United States Code Title 15 – 2310 That provision removes much of the financial risk of suing and gives the company a strong incentive to settle. To bring a Magnuson-Moss claim in federal court, the amount at stake must be at least $50,000. Smaller claims go to state court.
How Long You Have To File
Every state sets a deadline for filing a breach-of-contract lawsuit, called a statute of limitations. For written contracts, that window typically runs between four and ten years. Miss it and the court will dismiss your case no matter how strong it is. The clock usually starts when the breach occurs, though some states apply a “discovery rule” that starts it when you knew or should have known about the problem.
Solar cases can also run into a separate deadline called a statute of repose, which about 46 states apply to construction-related claims. A statute of repose sets an absolute outer boundary measured from when the project was substantially completed, and it can cut off your claim even if your statute of limitations hasn’t run out. If your state gives you four years from discovery to sue but has a seven-year statute of repose, and you don’t discover the defect until year six, you have one year left, not four.
Slow-degrading panel defects and small roof leaks may not become obvious for years. If you suspect something is wrong, investigate now. Waiting narrows every option you have.
Evidence That Makes or Breaks the Case
The signed contract is the foundation of any breach claim. Keep the original along with every addendum, change order, and financing agreement. These documents establish what the company promised: equipment specifications, performance guarantees, timelines, and warranty terms.
Collect every piece of written communication with the company. Emails, texts, and letters create a timeline showing when you reported problems and how the company responded. A pattern of ignored complaints or broken promises to send a repair crew builds a strong narrative for a judge or arbitrator.
Photograph and video any visible defects: improperly mounted panels, exposed wiring, water stains on ceilings, damaged drywall. Date-stamped visual evidence connects the company’s work to the damage you’re claiming.
Pull utility bills from before and after installation. Side-by-side comparisons are the most direct way to show that projected energy savings never materialized. Keep records of every payment you made to the solar company and every dollar you spent fixing problems the company caused. If you hire an independent inspector to evaluate the system, that report and invoice become key evidence. Independent solar inspections typically cost between $100 and $500 and can identify issues the company might deny.
Steps To Take Before You File
Read Your Contract for Dispute Resolution Clauses
Before you plan a lawsuit, read the fine print. Many solar contracts require mediation or binding arbitration instead of court litigation. Arbitration means presenting your case to a private arbitrator whose decision is usually final with very limited appeal rights. Mediation means negotiating through a neutral mediator before either side can file suit.
These clauses are common in the solar industry. Courts have occasionally found specific arbitration clauses unenforceable when the terms are heavily one-sided, but you should assume yours will be enforced unless an attorney advises otherwise. Skipping a mandatory arbitration step and going straight to court usually gets the case dismissed.
Send a Formal Demand Letter
Whether your contract requires it or not, send a written demand letter. Lay out the history of the dispute, identify the specific contract terms or warranties the company has breached, and list the damages you’ve suffered. State what resolution you want, whether a refund, system replacement, or repair, and give the company a firm deadline to respond, typically 30 days.
A demand letter serves two purposes. It sometimes prompts a settlement without litigation, especially when the letter shows you’ve documented the problem thoroughly. It also becomes evidence that you tried to resolve the matter in good faith before filing. Send it by certified mail with return receipt.
Consider Small Claims Court
If your damages are modest, small claims court may be faster and cheaper than a full civil lawsuit. Maximum claim limits vary by state, typically between $2,500 and $25,000. You represent yourself, filing fees are low, and cases are usually heard within a few weeks to a couple of months. Small claims works well for straightforward breach disputes where the company installed the wrong equipment or refused to honor a clear warranty obligation. Complex cases involving major property damage, fraud, or amounts above the dollar limit need a higher court.
What You Can Recover
Compensatory damages cover your actual financial losses: the cost of hiring a different company to fix or replace the defective system, reimbursement for payments made on work never properly completed, lost energy savings when the system underperforms its contractual guarantee, and repair costs for any property damage the installation caused. If your roof leaks because of negligent installation, the full cost of fixing the roof and any interior water damage counts.
Some solar contracts include a liquidated damages clause setting a predetermined amount the company owes for specific breaches, such as missing a completion deadline or failing to hit a performance target. These clauses can simplify your case because you don’t have to prove exactly how much you lost. The amount must be a reasonable estimate of the actual harm, though. If a court finds it grossly disproportionate to the real damage, it may refuse to enforce the clause. Review your contract for these provisions because they can either help or limit your recovery.
Punitive damages exist to punish especially bad behavior and deter it, and they aren’t tied to your financial losses. Courts award them in roughly 5% of verdicts, and the Supreme Court has established that gross negligence is the minimum threshold of misconduct required. Don’t count on punitive damages in a routine contract dispute, but they become a real possibility when a company engaged in deliberate deception.
Attorney’s fees can also come back to you. Some solar contracts include a provision making the losing party pay the winner’s fees. Even without such a clause, the Magnuson-Moss Warranty Act permits courts to award attorney’s fees to consumers who win warranty claims,3Office of the Law Revision Counsel. United States Code Title 15 – 2310 and state unfair and deceptive practices statutes often have similar fee-shifting provisions. Those rules can make a case financially viable that would otherwise cost more in legal fees than you’d recover.
A Separate Issue: Solar Liens on Your Title
If you leased panels or financed them through the installer’s lending partner, a UCC-1 filing may sit on your property title. That filing is a public notice that the solar company or lender has a security interest in the equipment on your property. A legitimate filing should have been clearly disclosed in your contract before you signed. When it wasn’t, or when the disclosure was buried in terms you never saw, the filing itself can be grounds for a legal claim, particularly when it delays a home sale or forces a costly refinance. Before signing any solar agreement, search the contract for UCC-1 or “fixture filing” language so you know what’s coming.
