TCPA SMS Rules for Solar Sales Reps (2026 State-by-State Guide)

For solar sales reps, the TCPA SMS rules in 2026 come down to five things: get prior express written consent before any automated text, only send between 8 AM and 9 PM in the recipient's local time, honor opt-outs within 10 business days, register for A2P 10DLC, and check whether the prospect's state (like Florida) imposes stricter limits.

Here is the complete answer. Automated marketing texts to a solar prospect, plus ringless voicemail and AI voice drops, require prior express written consent (PEWC) under 47 CFR 64.1200(f)(9). A purchased or broker lead list is not consent by itself. The federal quiet-hours window is 8 AM to 9 PM recipient local time. An Established Business Relationship (EBR) only exempts you from the National Do Not Call registry, not from PEWC. Consumers can revoke consent by any reasonable means under FCC 24-24, and you must process it within 10 business days. Before sending B2C SMS to US numbers you must register your brand and campaign through A2P 10DLC. Get any of this wrong and a single text can cost $500, or $1,500 for a willful violation, under the TCPA private right of action.

One more solar-specific note up front: there is no storm-solicitation ban for solar (those rules target roofing and restoration contractors), but solar installation generally requires a state electrical or home-improvement contractor license, and marketing solar without it can be a separate violation.

Do Solar Reps Need Consent Before Texting? (Yes — PEWC)

The single most important rule: you need prior express written consent (PEWC) before sending any automated marketing text, ringless voicemail, or AI voice message to a solar prospect. This is defined in 47 CFR 64.1200(f)(9).

Key takeaways:

• A purchased or broker lead list is NOT consent by itself. The vendor's consent does not transfer to you.
• PEWC must be a clear, affirmative agreement to receive automated marketing from your specific company.
• Ringless voicemail (RVM) and AI voice drops are treated like automated calls and need the same PEWC.
• The TCPA private right of action is $500 per violation, rising to $1,500 for willful violations — per message.

Run the math on a list: send 200 unconsented texts and you are exposed to up to 200 × $1,500 = $300,000 if violations are deemed willful.

Does an Established Business Relationship (EBR) Replace Consent?

No — and this trips up a lot of solar teams. An EBR is real, but narrow:

• 18 months from a purchase or transaction, or
• 3 months from an inquiry or application.

Here is the catch. EBR exempts you from the National Do Not Call registry ONLY. It does not replace PEWC for automated marketing texts or voicemail. And a company-specific opt-out always overrides EBR — if a homeowner told you to stop, the EBR does not bring them back.

What Are the Federal Quiet Hours for Solar Texts?

The federal TCPA quiet-hours window for marketing messages is:

8 AM – 9 PM

That is the recipient's local time, not yours. A rep in Florida texting a prospect in California has to respect Pacific time. Send at 7:59 AM or 9:01 PM local and it is a violation.

• Window applies every day, including weekends.
• It is based on the recipient's timezone, determined by where they are, not your office.
• There is no "urgent solar deal" exception.

Several states are stricter — Florida being the big one. When the state window is tighter than 8 AM–9 PM, the state window wins.

Florida FTSA: The Strictest State for Solar Texting

Florida's mini-TCPA, the Florida Telephone Solicitation Act (FTSA), Fla. Stat. 501.059, is the rule set most likely to catch solar reps off guard. Here is what it adds on top of federal TCPA.

Florida FTSA at a glance

Key Florida takeaways for solar reps:

• Quiet hours end at 8 PM, not 9 PM — one hour tighter than federal.
• Hard frequency cap: 3 calls, texts, or voicemails per 24 hours on the same subject to the same number.
• PEWC is required, but a checked box or an affirmative text reply counts.
• The 2023 HB 761 amendments added an EBR exemption and a text safe harbor: after a homeowner replies STOP, the sender has 15 days to cease.
• Ringless voicemail is explicitly covered as a "voicemail transmission" — RVM drops to Florida numbers count toward the 3-per-24-hour cap.

Are There Solar-Specific Solicitation Bans?

Good news here: solar has no storm-solicitation ban. Those post-disaster door-knock and solicitation restrictions target roofing and restoration contractors, not solar installers.

But two solar-specific compliance items still apply:

1. Licensing

• Solar installation generally requires a state electrical or home-improvement contractor license.
• Marketing solar without the required license can be a separate violation in states like FL, CA, and TX — independent of any TCPA issue.

2. Truthful claims

• Do not promise specific savings or bill reductions you cannot document for that specific home.
• Never imply you are a utility or government agency.
• Never describe the federal solar tax credit (the ITC) as a guaranteed rebate or check — it is a tax credit, not a payout.

How Do Solar Reps Handle Opt-Outs Correctly?

Under FCC 24-24, consumers may revoke consent by any reasonable means. Words like STOP, CANCEL, and QUIT are per se reasonable — you cannot require a specific magic word or a special process.

• Process revocation within 10 business days (federal).
• In Florida, the FTSA text safe harbor gives you 15 days to cease after a STOP reply.
• A company-specific opt-out overrides EBR — once they opt out, the relationship exemption does not bring them back.

What Is A2P 10DLC and Do Solar Reps Need It?

Yes. Before sending business-to-consumer SMS to US numbers, you must register your brand and campaign through A2P 10DLC. This is a carrier-level requirement (AT&T, Verizon, T-Mobile) layered on top of TCPA.

• Register your brand (your company identity) and your campaign (what you are texting about) before sending.
• Unregistered traffic gets filtered or blocked by carriers regardless of whether you have PEWC.
• This is separate from, and in addition to, your TCPA consent obligations.

Solar Rep TCPA Compliance Checklist

Before you send another text to a homeowner, confirm:

1. ☑️ PEWC on file? — Documented prior express written consent (47 CFR 64.1200(f)(9)), not just a purchased list.
2. ☑️ Quiet hours respected? — 8 AM–9 PM federal, 8 AM–8 PM in Florida, recipient local time.
3. ☑️ State limits checked? — Florida FTSA caps at 3 messages per 24 hours on the same subject.
4. ☑️ Opt-outs processed? — Within 10 business days (15 days under FL safe harbor); STOP/CANCEL/QUIT all honored.
5. ☑️ A2P 10DLC registered? — Brand and campaign registered before B2C SMS.
6. ☑️ Licensed? — State electrical or home-improvement contractor license where required.
7. ☑️ Claims documented? — No unverifiable savings promises; ITC described as a tax credit, not a guaranteed check.

If you cannot check every box, do not send until you can.

The Bottom Line for Solar Sales Reps

TCPA compliance is not the reason solar reps lose deals — sloppy texting is. The reps who win in 2026 are the ones who get consent right, stay inside the quiet-hours window for each prospect's state, honor every opt-out fast, and document it all.

The short version:

1. Get PEWC before any automated text or voicemail (47 CFR 64.1200(f)(9)).
2. Send only 8 AM–9 PM local (8 AM–8 PM in Florida).
3. Respect Florida's 3-per-24-hour cap and 15-day STOP safe harbor.
4. Process opt-outs within 10 business days (FCC 24-24).
5. Register A2P 10DLC and keep your contractor license current.
6. Make only claims you can document.

Do it right and SMS becomes your highest-ROI channel. Do it wrong and every message is a $1,500 gamble.
