Suing a Solar Company: When to File UDAP/DTPA Claims vs. Small Claims or Civil Court

Disclaimer: This article is for informational purposes only and does not constitute legal advice. The appropriate legal forum depends on the specific facts of your case, the damages sought, applicable state law, and the contract terms (including arbitration clauses). Consult an attorney before filing any legal action.

Overview

You were promised a monthly payment that would be lower than your utility bill. You were told the panels would cover all of your electricity. You were assured there would be no hidden costs. None of it happened. Now, after attempting to resolve the dispute directly — and getting nowhere — you are asking the question thousands of solar homeowners ask every month: how do I sue a solar company?

The answer depends on the type and amount of your damages, the legal theory of your claim, and — critically — whether your contract contains a mandatory arbitration clause. This guide provides a high-level overview of the available legal avenues and when each is appropriate.

Step Zero: Check for an Arbitration Clause

Before you evaluate any court-based remedy, find your contract and locate the arbitration provision. Almost all solar contracts specifically restrict your right to sue and instead try to substitute some kind of arbitration process, which is almost always skewed in favor of the company.

Most SunRun contracts, for example, include mandatory arbitration — blocking customers from joining class actions. The CPUC receives a high volume of solar complaints, and SunRun alone has accumulated over 4,000 complaints in the last three years — an unusually high number for a residential solar company.

If your contract mandates arbitration, your ability to file in court — small claims or otherwise — may be limited. Arbitration clauses can sometimes be challenged on enforceability grounds (unconscionability, lack of mutual assent, failure to disclose), but this is a complex legal argument that requires an attorney.

Avenue 1: Small Claims Court

Small claims court is the most accessible forum for consumers. It handles disputes up to a statutory maximum — typically $5,000 to $10,000, depending on the state. Claims exceeding the small claims limit must be filed in a higher court or reduced (waiving the excess amount).

Best for: Minor solar installation issues, incomplete work, cost of repairs, claims within the statutory limit, situations where arbitration is not mandated.

Advantages:

No lawyer required. Filing fees are minimal.
Cases resolve relatively quickly — often within 60 to 90 days.
Judges are accustomed to pro se litigants.

Limitations:

Damages capped at the statutory maximum (typically $10,000).
Discovery is limited.
The solar company may remove the case to a higher court if it has counsel.
An arbitration clause may block small claims jurisdiction.

Avenue 2: UDAP / DTPA Statutory Claims

Most states have an Unfair or Deceptive Acts or Practices (UDAP) statute — sometimes called a Consumer Protection Act or Deceptive Trade Practices Act. These statutes provide private rights of action for consumers who were misled or deceived in a transaction.

Best for: Cases involving fraudulent inducement, misrepresentation of savings, failure to disclose material contract terms, and deceptive sales practices.

Key features of a UDAP/DTPA claim:

Many UDAP statutes allow for treble (triple) damages or statutory minimum damages.
Attorney's fees are often recoverable — making these cases viable for contingency-fee representation.
The legal standard varies by state: some require "unfair or deceptive" conduct, others require a higher showing of intent or reliance.

Examples of viable UDAP/DTPA claims against solar companies:

The salesperson promised the system would eliminate your utility bill entirely. It did not, and the company refuses to honor the promise because it was not in the written contract. This is a classic fraudulent inducement scenario.
The installer misrepresented its relationship with the local utility — a common sales tactic. Vivint Solar paid $4.3 million to settle allegations that it misrepresented its relationship with utility companies, projected energy savings or costs, and consumers' ability to cancel PPAs.
The company failed to disclose dealer fees embedded in the financing, inflating the principal balance. The Minnesota Attorney General investigated four large solar-lending companies (GoodLeap, Sunlight Financial, Solar Mosaic, and Dividend Solar Finance) and uncovered $35 million in hidden fees on nearly 5,000 loans.

Enforcement context: In 2026, the Florida Attorney General launched an initiative targeting fraudulent and deceptive practices in the solar panel industry — focusing on alleged misrepresentations concerning projected energy savings, system performance, installation practices, and contractual terms. The FL AG issued Civil Investigative Demands (CIDs) seeking documentation regarding how companies substantiate energy savings claims, warranties, marketing materials, and contract terms.

Regulators at both the state and federal levels are ramping up enforcement — with a growing focus on whether companies are overstating projected energy savings, system performance, pricing, and financing terms.

Avenue 3: Civil Court (Beyond Small Claims)

For claims exceeding the small claims limit — or where the legal complexity demands formal litigation — filing in a state or federal civil court is appropriate.

Best for: Claims involving substantial damages (tens of thousands of dollars), multiple defendants, class actions, or complex legal theories.

Advantages:

No damages cap.
Full discovery — depositions, document requests, interrogatories.
Potential for jury trial.

Limitations:

Significantly more expensive and time-consuming.
Legal representation is essential.
Arbitration clauses may block or delay court proceedings. The New York Attorney General, for example, filed suit in 2026 alleging deceptive pricing and misconduct by a solar company and its lenders — illustrating that major actions can be brought outside of arbitration when pursued by regulators or in cases where arbitration is not enforceable.

Before Filing: Pre-Litigation Steps

Send a demand letter. By certified mail, state the specific claims, the damages sought, the legal basis, and a deadline for resolution (typically 30 days). Many disputes settle at this stage — especially when the demand is well-documented and cites applicable statutes.
Document everything. Call logs, emails, texts, marketing materials, the contract, payment records, production data. Dates matter in breach and fraud claims.
Check the contractor's license status. If the installer's license is suspended or revoked, this strengthens a fraud or negligence claim.
File regulatory complaints. BBB, FTC, CFPB, state AG, and state contractor licensing board. These complaints create a public record that can be used in litigation.
Consult a solar fraud attorney. An experienced attorney can evaluate the viability of a UDAP/DTPA claim, the enforceability of any arbitration clause, and the appropriate damages calculation.

FAQ

Can I sue a solar company if my contract has an arbitration clause?

Generally, the arbitration clause must be enforced — but exceptions exist. An attorney can evaluate whether the clause is unconscionable, was not adequately disclosed, or is otherwise unenforceable under state law.

How much does it cost to sue a solar company?

Small claims court filing fees are typically $30 to $100. Civil litigation costs vary widely. UDAP/DTPA claims that allow for attorney's fee recovery may be handled on a contingency basis.

What damages can I recover in a solar fraud lawsuit?

Depending on the legal theory: actual damages (out-of-pocket losses, overpayments, repair costs), statutory damages under UDAP/DTPA, treble damages, and in some cases, punitive damages for intentional fraud.

How long do I have to sue?

Statutes of limitations vary by state and claim type — typically 2 to 4 years for fraud and UDAP claims, but can be shorter for breach of contract. Do not wait. Consult an attorney promptly after discovering the issue.
