TL;DR
When a solar rep knocks a door and then calls or texts that homeowner, the company needs prior express written consent under TCPA before any autodialed or prerecorded contact. Oral consent at the door is not enough for calls to cell phones. The consent must be signed, clearly describe the seller, and survive an audit. One missing link in the chain exposes the company to $500 to $1,500 per call or text.
What is the TCPA consent chain for solar door-to-door sales?
The consent chain is the documented sequence of permissions a solar company collects, transfers, and stores so that every call or text a homeowner receives after the door knock is covered under the Telephone Consumer Protection Act, 47 U.S.C. § 227 [1]. Picture a paper trail (or a digital one) that connects the moment a rep stands on a porch to the moment a phone rings days later.
Here is the failure mode in solar specifically. A rep knocks, has a great conversation, and the homeowner says "sure, call me." The rep writes the number on a clipboard and hands it to a call center. The call center autodials the next morning. That sequence has two legal holes: the verbal "sure, call me" does not meet the written consent standard for autodialed calls to cell phones, and there is no documented disclosure that the homeowner agreed to autodialed contact on behalf of a named seller.
Every link has to hold. Consent gets collected properly. It transfers to whoever does the calling without alteration. And the company has to prove all of it in court years later, because TCPA carries a four-year statute of limitations under 28 U.S.C. § 1658 [2].
Solar is a high-litigation vertical. Class action attorneys actively recruit plaintiffs here, and the Federal Communications Commission has flagged solar lead generation as an enforcement priority in recent orders [3].
What does TCPA actually require for calls and texts after a door knock?
The statute at 47 U.S.C. § 227(b)(1)(A) bars using an automatic telephone dialing system or a prerecorded voice to call any cell phone without "prior express consent" of the called party [1]. The FCC's 2012 order (FCC 12-21) went further: telemarketing calls and texts need "prior express written consent," a higher bar than plain consent [4].
The FCC defines prior express written consent as an agreement that (1) bears the signature of the person called (electronic signatures count under E-SIGN), (2) clearly authorizes the seller to deliver telemarketing calls or texts using an autodialer or prerecorded voice, (3) identifies the phone number to be called, and (4) is not a condition of buying anything [4].
For solar door-to-door work, that means the rep cannot get a verbal yes and walk. The homeowner signs something. A paper form, a tablet e-signature, or a web form the homeowner fills out on the spot. The signature does not need to be fancy. It needs to exist.
Calls to landlines with a live human (no autodialer, no prerecorded message) follow a lower standard. Plain prior express consent covers those, no written form required. But most solar call centers autodial, so the written standard governs almost every follow-up call in this business.
One more thing. The National Do Not Call Registry runs separately from TCPA consent. A homeowner can give you valid written consent and still sit on the DNC list. Check the do not call list before calling, unless you have a documented established business relationship or the person specifically asked you to call. The FTC enforces DNC. The FCC enforces TCPA. Different regimes, different penalties.
Does a verbal yes at the door count as TCPA consent?
No. Not for autodialed or prerecorded calls to a cell phone. Full stop.
Oral consent at the door works only if all three are true: the call goes to a landline, you use a live agent with no autodialer, and you leave no prerecorded message. If any one of those is false, the verbal yes gives you nothing.
This trips small solar teams constantly. The rep has a real, warm conversation. The homeowner genuinely wants follow-up. The rep feels confident. But no written signature gets captured, so when the call center autodials that cell number three days later, the company is exposed for every call in the batch.
The FCC's 2012 order says it plainly: "Prior express written consent means an agreement, in writing, bearing the signature of the person called." [4] Oral agreement is not writing. A rep's field note reading "HO said yes" is not writing that satisfies this standard.
Some teams try to patch the gap by having the homeowner confirm consent on a recorded inbound call. That is a gray area, and it invites a fight. The clean move is to get the signature at the door, before any outbound autodialed contact happens.
How should a solar rep collect valid written consent at the door?
You have three real options. Each has trade-offs.
Option one is a paper consent form. The rep carries a short form that says, in plain language, something like: "By signing below, I agree to receive autodialed or prerecorded sales calls and text messages from [Company Name] at the phone number I have provided above. My agreement is not a condition of any purchase." The homeowner signs, the rep photographs it immediately, and the original goes into the file. This works. It is low-tech, survives audits, and reads clean to a jury. The downside: physical paper gets lost, and the transfer to the call center has to be documented with care.
Option two is a tablet or mobile e-signature. The rep hands over a tablet. The homeowner reads the disclosure and signs with a finger or stylus. The signature is timestamped, geotagged, and synced to a CRM automatically. This is the best option for teams running volume, because the chain of custody is automatic. The electronic signature is valid under the E-SIGN Act (15 U.S.C. § 7001) [5]. Make your software log the IP address or device ID, the timestamp, and the exact disclosure text the person saw.
Option three is sending the homeowner a link to a web form they complete on their own phone. The rep asks for the number, sends a link by SMS or email, and waits. The problem here is circular: sending that initial SMS to a number you do not yet have consent to text is itself a potential TCPA issue. The workaround is to have the homeowner type their own number into the tablet form instead of the rep texting them. That sidesteps the bootstrap problem.
Whatever the method, the form has to name the specific seller (the actual company that will call), never a vague "solar companies" or "energy providers." Vague disclosures are the second most common reason consent gets thrown out in litigation, right behind missing signatures.
What information must the consent form include to be legally valid?
The FCC's 2012 order and later guidance give a clear list [4]. A valid prior express written consent for telemarketing calls has to carry all of the following.
| Required Element | What It Means in Practice |
|---|---|
| Signature of the called party | E-signature or wet ink; must be the person whose number is listed |
| Authorization to use ATDS or prerecorded voice | Must specifically mention autodialer or prerecorded calls, beyond "contact" |
| Telephone number to be called | The specific number, typed or written by the homeowner |
| Clear identification of the seller | The company name that will actually call, never a generic description |
| No purchase condition | A statement that consent is not required to buy anything |
| Date and time of consent | Good practice; required by most state laws and helpful in disputes |
A few additions that the FCC does not strictly require but any litigation-hardened compliance team includes: the rep's name and ID number, the physical address of the door knock (for geographic proof), and the exact disclosure text shown. Drop the "not a condition of purchase" language and courts have voided consent that was otherwise perfect.
For SMS-specific consent, you also tell the homeowner the message frequency ("you may receive up to X messages per month") and give opt-out instructions ("reply STOP to unsubscribe"). The CTIA's messaging guidelines say the same, and carriers increasingly enforce it at the network level [6].
How does the consent transfer from the field rep to the call center?
This is the link most solar companies get wrong. It is where class actions are won and lost.
Getting valid consent at the door is half the job. The consent has to reach the entity making the calls with every attribute intact: the timestamp, the exact number, the seller's name, and the scope of what the homeowner agreed to. If your call center is a separate legal entity from the solar company, you need a data transfer agreement that documents the chain of custody.
A clean transfer looks like this. The rep captures the e-signature on a tablet. The consent record syncs to a CRM, tagged with a unique lead ID. The call center pulls the lead and sees the full consent record before dialing. Every outbound call logs against that record. If the homeowner disputes the call, the company produces the exact consent, timestamp and disclosure text included, in under five minutes.
A broken transfer looks like this. The rep fills out a paper form. The form goes into a folder. Someone at the office keys the number into a spreadsheet. The spreadsheet gets emailed to the call center. Three weeks later nobody can find the original form, the spreadsheet has no timestamps, and the consent record is gone.
The FCC's 2023 lead generation order (FCC 23-107) took direct aim at multi-party consent chains in solar [3]. The FCC required consent on a one-to-one basis, meaning the homeowner specifically identifies each seller they consent to, rather than consenting to "solar companies" as a category. Where that rule is in force, blanket consent forms that transfer to multiple call centers are invalid. The rule has drawn court challenges, so check its current status before building any process around a multi-seller consent form.
For a broader look at cold calling compliance, including the rules that apply before any consent exists, that guide covers the legal baseline for any outbound team.
What are the TCPA penalties if the consent chain breaks down?
The statute sets $500 per violation for negligent violations and $1,500 per violation for willful or knowing ones [1]. Each call or text is a separate violation. Each person in a class action is a separate plaintiff.
The math turns ugly fast. A call center that makes 10,000 autodialed calls with defective consent faces up to $5 million in statutory damages at $500 per call, before any willfulness multiplier. If a court finds the violation willful, that becomes $15 million. Solar companies have settled TCPA class actions in the tens of millions of dollars. The cash app TCPA class action settlement and cases like it show how quickly aggregate liability climbs when the underlying consent was defective across a large list.
In 2023, the FCC also ruled that prior express written consent cannot be transferred through a lead list purchase without meeting one-to-one consent requirements [3]. That ruling took direct aim at the solar lead generation ecosystem, where companies buy lists of homeowners who allegedly consented to solar calls. Purchased consent is the riskiest form of consent in this industry right now.
State laws stack on top. Florida, Oklahoma, and several other states have mini-TCPA laws with per-violation damages that can exceed the federal baseline. If your territory includes Florida homeowners, you also operate under the Florida Telephone Solicitation Act, which has its own written consent rules and a $500 per call penalty that bites even when a call clears the federal standard [7].
Does the FCC's 2024 one-to-one consent rule change anything for solar?
Yes, substantially, though litigation has scrambled the timeline.
The FCC adopted rules in December 2023 (effective January 2025) requiring prior express written consent for telemarketing calls to be specific to a single seller, never a category of sellers [3]. The old trick of capturing consent on a comparison website or lead form that says "I agree to be contacted by solar companies," then selling that consent to a dozen installers, is invalid under the new rule.
The rule also requires the consent to be logically and topically related to the website or interaction where it was collected. Fill out a form on a home energy efficiency site that discloses solar calls, and that is arguably fine. Bury solar consent inside a sweepstakes entry, and that is not.
For door-to-door solar teams the practical effect is good in one sense: you already capture consent directly from the homeowner, with your company named as the caller. That is exactly what one-to-one requires. The pain lands on lead generation vendors who sell you "consented" numbers from third-party web forms. Those leads got significantly riskier to call after 2025.
The Eleventh Circuit stayed part of the rule in early 2025, so the exact effective date and scope of the one-to-one requirement were still in litigation as of mid-2026. Check the FCC's website directly for current status before relying on any summary, this one included [3].
How long do you need to keep consent records?
TCPA's statute of limitations is four years under 28 U.S.C. § 1658 [2]. So keep consent records for at least four years from the date of the last call or text made under that consent.
Most compliance teams keep records five years to build in a buffer. For state-level claims, check your state's limitations period for consumer protection claims. Some states allow claims to reach back six years, so a five-year retention policy may fall short if your territory touches those states.
The records you need go past the signed form. You need the consent record itself (signature, timestamp, disclosure text), a log of every call and text made under that consent (date, time, number dialed, duration or delivery status), proof the number was scrubbed against the do not call list before the call, and any revocation of consent (a STOP reply, a verbal request to stop, an email asking to be removed).
Revocation of consent is immediate under the FCC's 2024 guidance. If a homeowner says "do not call me again" in any medium, all outbound contact to that number stops. You cannot force a homeowner to use a specific opt-out method (like a web form) once they have already revoked orally or by text [11].
What should a solar company's internal consent audit look like?
An audit does not need to be expensive or elaborate. It needs to be honest and documented.
Start with a random sample of 50 to 100 recent leads that got autodialed calls or texts. For each lead, ask one question: can I produce a signed consent record that names our company, includes the homeowner's phone number, and predates the first call? If you cannot produce that record for more than 10 to 15 percent of sampled leads, you have a systemic problem, not a clerical one.
Next, trace the transfer chain for five of those leads. Find the original consent record (paper scan, e-signature log, or CRM entry). Confirm the number in the record matches the number dialed. Confirm the consent timestamp predates the first call. Confirm the disclosure text actually mentions autodialing, beyond "contact."
Then check your DNC scrub logs. Can you show, for each lead, that the number was checked against the National DNC Registry within the 31-day window FTC rules require [8]? No proof of the scrub means a separate exposure under the Telemarketing Sales Rule.
LeadCompliant's compliance kit includes a consent audit template and a DNC scrub checker if you want a starting framework. Run the audit quarterly, rather than only after a lawsuit lands. The time to find a broken consent chain is before a class action attorney does.
For teams new to this, the TCPA basics guide covers the full regulatory picture before you get into any single vertical.
What state laws add extra requirements on top of TCPA for solar telemarketers?
Several states run statutes stricter than the federal TCPA, and solar companies operating nationally have to layer all of them.
Florida's Telephone Solicitation Act (FTSA) requires written consent for autodialed calls and texts to Florida residents, applies to calls made from out of state, and carries a $500 per call private right of action [7]. Florida became a hotbed for this litigation because the state right of action does not force the plaintiff to prove the caller used an ATDS, the federal definition that Facebook v. Duguid narrowed at the national level [10].
California's Invasion of Privacy Act and related consumer protection statutes add recording consent rules and extra teeth for solar companies calling into the state. Maryland, Texas, and Washington each require telemarketing registration that solar companies making outbound calls have to satisfy before dialing [9].
State DNC lists exist separately from the federal registry in some states. Colorado and Indiana run their own. Scrubbing only against the federal do not call telemarketer list is not enough if your leads include residents of states with their own registries.
One underappreciated wrinkle for solar is the split between residential and cell phone rules at the state level. Some state laws reach calls to any phone used for residential purposes, cell or landline. If a homeowner uses a cell phone as their main home number, several state laws treat it as a residential line for solicitation purposes.
What does a legally sound consent form look like in practice?
Here is the plain-language structure every solar door-to-door consent form should follow. This is a template structure, not legal advice. Have your own attorney review the final version.
At the top: the homeowner's name and the phone number they consent to have called (ideally written or typed by the homeowner, not pre-filled by the rep).
The consent language, in plain English: "I, [Name], agree to receive autodialed calls, prerecorded voice messages, and text messages from [Exact Company Name, including state of incorporation or DBA] at the phone number listed above. I understand that my agreement is not a condition of purchasing any goods or services. Message and data rates may apply. I may opt out at any time by replying STOP to any text message or by calling [company phone number]."
Below that: a signature line (wet ink or e-signature), a date field, and the rep's name and ID number.
Optional but smart: a checkbox reading "I have read and understand the above disclosure" that the homeowner checks before signing. In litigation, that shows the disclosure was not hidden in fine print.
What to avoid: combining the consent with a financing agreement, a free estimate request, or any document where the consent language could read as a condition of service. Courts have struck down consent buried in service agreements where refusing to sign meant the homeowner could not get the estimate.
Frequently asked questions
Can I call a homeowner back the same day using a prerecorded message if they said yes at the door?
No. A verbal yes at the door does not meet the prior express written consent standard for prerecorded calls to a cell phone. The FCC's 2012 order requires a signed agreement before any autodialed or prerecorded telemarketing call. If you left the door without a signature, you can make a live-agent call to a landline, but you cannot autodial or leave a prerecorded message on any phone without written consent first.
What happens if the homeowner gives consent but is on the National Do Not Call Registry?
DNC registration and TCPA written consent are separate requirements that both apply. A homeowner on the federal DNC registry can still receive calls if they gave you prior express written consent, because written consent works as an exception to DNC rules. But you still need that written consent and must prove it. If you rely on the established business relationship exemption instead, the call must occur within 18 months of the last transaction under FTC regulations.
Is an e-signature captured on a tablet at the door legally valid TCPA consent?
Yes, assuming it meets E-SIGN Act requirements (15 U.S.C. § 7001). The signature must be attached to or logically associated with the consent form, and the system must keep a record of the signing process including timestamp and the exact disclosure text displayed. The homeowner must have affirmatively signed, beyond tapping a button that auto-populated their signature. Most purpose-built field sales tablet apps meet these requirements; a generic PDF with a typed name may not.
Can I buy a list of solar leads and call them if the list provider says the leads are TCPA-consented?
This is the highest-risk practice in solar lead generation right now. The FCC's 2023 order requires one-to-one consent naming the specific seller, which makes consent captured on a comparison site and sold to multiple companies legally questionable. If you buy a list and the consent is defective, you are the one making the call and you are the one liable. Verify the consent chain for any purchased list independently, ideally by having your own attorney review the provider's consent forms.
What does the FCC's one-to-one consent rule mean for solar door-to-door teams specifically?
Door-to-door teams sit in a better spot under the one-to-one rule than lead buyers, because you capture consent directly from the homeowner with your company named on the form. The rule is a bigger headache for companies that purchase pre-consented leads. The main change for field teams is making sure your consent form names your company specifically, never a generic category like "solar energy providers."
How do I scrub my solar lead list against the Do Not Call Registry?
Under FTC regulations, telemarketers must scrub against the National DNC Registry every 31 days. You register as a telemarketer, pay the annual fee (currently $79 per area code, with the first five area codes free), and download or query the registry before each campaign. Your CRM or dialer may have built-in DNC scrubbing. Check the FTC's website for current fees and area code pricing, as they change periodically. State-level DNC lists require separate subscriptions.
Can a homeowner revoke TCPA consent after giving it at the door?
Yes, at any time and through any reasonable means. The FCC's 2024 guidance confirms consent revocation is immediate and irrevocable, and you cannot require the consumer to use a specific opt-out method. If a homeowner texts STOP, tells a live agent "don't call again," or emails asking to be removed, all autodialed and prerecorded contact to that number must stop immediately. Keep calling after revocation and a consent dispute becomes a willful violation, tripling the potential damages.
What is the statute of limitations for TCPA lawsuits related to solar calls?
Four years from the date of the alleged violation, under 28 U.S.C. § 1658. For state-level claims, the limitations period varies by state. Florida's FTSA has its own limitations period that may differ. So retain consent records, call logs, and DNC scrub documentation for at least four years from the last call made under any given consent record, and longer if your territory includes states with extended limitations periods.
Does TCPA apply to text messages sent to solar prospects after a door knock?
Yes. The FCC confirmed in 2003 that text messages fall under TCPA on the same standard as calls. Autodialed texts to cell phones require prior express written consent for marketing messages. The form used at the door must specifically mention text messages, beyond calls, if you plan to follow up by text. The CTIA also requires marketing text programs to include opt-out instructions and message frequency disclosures, and major carriers enforce these standards at the network level.
How is the TCPA consent chain different when a third-party lead generator is involved?
When a lead generator captures consent on your behalf, you rely on their consent process, their disclosure language, and their transfer controls. If any of those break down, you carry the liability for the calls you make. The FCC's 2023 order tightened this by requiring one-to-one consent that names the specific seller. Before using any third-party lead generator, review their consent form, verify it names your company specifically, and get contractual representations that their process is TCPA-compliant, backed by indemnification.
What penalties apply to solar companies that violate TCPA in states like Florida?
Federal TCPA penalties are $500 per violation, tripled to $1,500 for willful violations. Florida's FTSA adds a separate $500 per call right of action for state residents, and Florida courts have found the FTSA applies even when the caller argues the ATDS definition under Facebook v. Duguid would not cover their system. Other states run similar overlay statutes. A solar company calling Florida homeowners with a defective consent chain faces liability under both the federal statute and the Florida statute for the same calls.
Do I need a separate consent for texts versus calls in solar door-to-door sales?
Not necessarily a separate form, but the consent must specifically authorize both if you plan to use both channels. A form that mentions only "calls" does not cover texts. A form that mentions "calls and text messages" covers both. The CTIA's messaging guidelines also require text-specific disclosures, including opt-out instructions and message frequency, to appear in the consent. Many solar teams use a single form covering calls, texts, and prerecorded messages in one disclosure paragraph.
What is the difference between prior express consent and prior express written consent?
Prior express consent (oral or written, any form) covers non-telemarketing calls and live-agent calls to landlines. Prior express written consent, meaning a signed agreement, is required for telemarketing calls and texts made using an autodialer or prerecorded voice to a cell phone. Since most solar follow-up calls are autodialed and go to cell phones, the written standard applies in the overwhelming majority of door-to-door solar situations. When in doubt, get the written signature.
