Texas’s Solar-Sales Law Takes Full Effect September 1, 2026 — What to Check Before You Sign
Quick Summary: Starting September 1, 2026, the registration and enforcement half of Texas Senate Bill 1036 kicks in: companies that sell residential solar — and the salespeople who knock on your door — must be registered with the state, and bans on deceptive solar-sales tactics become enforceable. It’s a consumer-protection law, not an electricity-rate change, but it matters to any Texas household weighing a rooftop-solar pitch. And it doesn’t change the first question you should still answer: what you really pay for grid power today.
What Actually Changes on September 1
Senate Bill 1036, passed by the 89th Texas Legislature, created a Residential Solar Retailers program at the Texas Department of Licensing and Regulation (TDLR) under Occupations Code Chapter 1806. The law rolled out in two phases. The consumer-contract rules — including the right to cancel — have applied to contracts signed on or after September 1, 2025. The second phase lands now.
According to TDLR’s official “What’s in Effect When” guidance and reporting from FOX 7 Austin / FOX 26 Houston (Aug. 28, 2026), beginning September 1, 2026:
- Residential solar retailers and their salespersons must be registered with TDLR to sell or lease residential solar panels and systems in Texas.
- Companies must carry insurance and supervise their salespeople.
- The law’s prohibited acts become enforceable and subject to administrative action.
The prohibited acts, as summarized in the coverage, include making deceptive claims, falsely implying an affiliation with a utility or a government program, ignoring a home’s “no soliciting” sign, and performing unlicensed installation. Regulators can impose penalties, order cancellations and refunds, and seek higher penalties when the victim is 65 or older.

Why a Solar Law Belongs on an Electricity-Shopping Site
Rooftop solar is one of the biggest energy decisions a Texas household can make, and it is almost always sold on a promise about your electricity bill — “lock in your rate,” “replace your utility payment,” “you’ll save thousands.” The problem regulators are trying to fix is that some of those pitches were built on aggressive door-to-door tactics and rosy, unverifiable savings math. Requiring sellers to register and banning false utility or government affiliations gives you a way to check who you’re dealing with before a 20-year financial commitment.
It’s worth being precise about what this law is and isn’t. It does not change your electricity rate, your TDU delivery charge, or which retail plan is cheapest for your home. Those are set the way they always are — the regulated delivery charge is identical for every provider in your area, and the competitive energy rate is the part you shop. What the law does is add guardrails to the sales process for a specific product: residential solar.
A Checklist Before You Sign a Solar Deal
| Step | Why It Protects You |
|---|---|
| Confirm the seller is TDLR-registered | As of Sept. 1, 2026, unregistered residential solar sales are not allowed. |
| Check the contract names a licensed electrical contractor | The agreement must state who installs the system and their license number. |
| Know your 5-business-day cancellation window | You can cancel in writing without penalty; an affiliated loan cancels too. |
| Treat “we’re from your utility” as a red flag | Falsely implying a utility or government affiliation is now a prohibited act. |
| Verify the savings math against your real bill | A quote’s “savings” is only as honest as the current cost it assumes. |
The Consumer Takeaway
The new registration and enforcement rules give Texas homeowners real leverage against a high-pressure solar pitch — slow it down, ask for the seller’s registration, read the cancellation clause, and don’t sign under a deadline that expires today. But the single most useful thing you can do before a solar rep ever knocks is to know your true electricity cost, because that is the number every solar “savings” projection quietly leans on.
Most solar pitches start from your advertised or headline rate, not what you actually pay across a full year of real usage — the same 1,000 kWh illusion that makes some regular electricity plans look cheaper than they are. Price your current plan at your real monthly usage first, and you’ll have an honest baseline to judge whether a solar quote — or simply switching to a better-fit fixed-rate plan — is the better deal.
Solar can be a good decision for the right home. Just make sure the person selling it is registered, the contract is cancelable, and the “savings” are measured against what you really pay — not a number designed to make the pitch look good.
