Using the Texas Deceptive Trade Practices Act Against a Solar Installer

If you're a Texas homeowner whose solar installer won't honor a production guarantee, the state's main consumer-protection law is the Deceptive Trade Practices–Consumer Protection Act — the DTPA. It carries real teeth: economic damages, the possibility of up to triple damages for knowing or intentional conduct, and recovery of your attorney's fees. It also has a distinctive procedural step: a 60-day written notice before you sue. This page explains what the DTPA says, how it can relate to a production-guarantee shortfall, and that 60-day notice.

What the DTPA Prohibits

The DTPA, Business & Commerce Code §17.41 and following, declares deceptive trade practices unlawful in broad terms:

"False, misleading, or deceptive acts or practices in the conduct of any trade or commerce are hereby declared unlawful…" — Tex. Bus. & Com. Code § 17.46(a). Source: statutes.capitol.texas.gov (verified 2026-06-19).

Section 17.46(b) then lists a long, specific catalog of practices that count as false, misleading, or deceptive — including representing that goods or services have characteristics or benefits they do not have. A consumer's private claim runs through §17.50, which (among other grounds) lets a consumer sue for a §17.46(b) practice relied upon to the consumer's detriment, or for breach of an express or implied warranty.

How the DTPA Can Relate to a Production-Guarantee Dispute

A production guarantee is a contract term, and Texas courts have been clear that a mere breach of contract is not, by itself, a DTPA violation. What can bring an installer's conduct within the statute is a deceptive practice the consumer relied on (for example, a misrepresentation of what the system would produce) or a breach of warranty — both of which §17.50(a) lists as grounds. Whether a particular installer's conduct fits one of those grounds is fact-specific and is the judgment a licensed Texas attorney makes — not something OwlWatt or this page can decide for you. What OwlWatt provides is the factual foundation: a documented, weather-adjusted production shortfall measured against your contract's guarantee.

The 60-Day Pre-Suit Notice (Section 17.505)

The DTPA's signature procedural requirement is a written notice before suit. Section 17.505(a) states it directly:

"As a prerequisite to filing a suit seeking damages under Subdivision (1) of Subsection (b) of Section 17.50… against any person, a consumer shall give written notice to the person at least 60 days before filing the suit advising the person in reasonable detail of the consumer's specific complaint and the amount of economic damages, damages for mental anguish, and expenses, including attorneys' fees, if any, reasonably incurred by the consumer in asserting the claim against the defendant." — Tex. Bus. & Com. Code § 17.505(a). Source: statutes.capitol.texas.gov (verified 2026-06-19).

Three things follow:

• The notice must state the complaint and the amounts. A vague grievance won't do — the notice has to describe the specific complaint in reasonable detail and state the amount of economic damages and expenses. A documented production shortfall with a dollar figure is exactly the kind of specific, sourced amount the statute contemplates.
• There's a 60-day window — and an inspection right. During the 60 days, the business may request to inspect the goods at issue. The window gives the parties a chance to resolve the dispute before litigation.
• There are narrow exceptions. Per §17.505(b), the 60-day notice is not required if it is impracticable because suit must be filed to prevent a limitations bar, or where the claim is asserted as a counterclaim — but a tender may still be made within 60 days of service.

OwlWatt's separate free demand-letter template is a generic starting point for documenting a shortfall in writing. A DTPA §17.505 notice has specific legal requirements, so in Texas a licensed attorney should prepare or review it.

Economic Damages, Treble Damages, and Attorney's Fees

The reason the DTPA is taken seriously is the remedy. Section 17.50(b) sets out the tiers:

"In a suit filed under this section, each consumer who prevails may obtain: (1) the amount of economic damages found by the trier of fact. If the trier of fact finds that the conduct of the defendant was committed knowingly, the consumer may also recover damages for mental anguish… and the trier of fact may award not more than three times the amount of economic damages; or if the trier of fact finds the conduct was committed intentionally, the consumer may recover damages for mental anguish… and the trier of fact may award not more than three times the amount of damages for mental anguish and economic damages…" — Tex. Bus. & Com. Code § 17.50(b). Source: statutes.capitol.texas.gov (verified 2026-06-19).

In plain terms: economic damages by default, mental-anguish damages plus up to three times economic damages for a knowing violation, and up to three times mental-anguish and economic damages for an intentional one. Note these multipliers are discretionary ("may award… not more than three times") and depend on a finding of knowing or intentional conduct — they are not automatic. On fees, §17.50(d) is mandatory:

"Each consumer who prevails shall be awarded court costs and reasonable and necessary attorneys' fees." — Tex. Bus. & Com. Code § 17.50(d). Source: statutes.capitol.texas.gov (verified 2026-06-19).

The fee-shifting is significant for a homeowner: a prevailing consumer recovers reasonable and necessary attorney's fees and costs, which changes the economics of an otherwise modest claim.

What This Means in Practice

If you're a Texas homeowner facing a production-guarantee shortfall, the steps are:

1. Document the shortfall. You need a specific, weather-adjusted figure — guaranteed kWh, actual kWh, and the dollar amount — not a vague complaint about low production. The §17.505 notice asks for the amount of your economic damages.
2. Talk to a licensed Texas attorney. The DTPA reaches specific grounds, the 60-day notice has formal requirements, and the knowing/intentional findings that unlock multiplied damages are exactly what a consumer attorney evaluates. An attorney can also tell you whether your facts support a DTPA claim or a straight breach-of-contract claim.
3. Send a compliant §17.505 notice. Describe the complaint in reasonable detail, state your economic damages and expenses, and attach your documentation. Then the 60-day clock runs.
