SMS Follow-Up Cadence for Solar Reps: What Actually Works in 2026

You knocked the door, talked to the homeowner for ten minutes, and walked away with a "send me some info." You added them to your CRM. Now what?

Most reps either go silent (the lead goes cold) or carpet-bomb the homeowner with daily generic messages (the lead blocks the number). Neither works. The cadence below is what actually converts in 2026 for residential solar sales, broken down by lead stage.

Why SMS works for solar (and why most reps still get it wrong)

Solar lead conversion is a trust problem. The homeowner is being asked to put a $30,000 system on their roof from a company they had never heard of an hour ago. SMS works because it is the most personal high-volume channel: it lands on their lock screen, they read it within 3 minutes 95% of the time, and a real conversation can happen there.

The reason most reps fail at SMS follow-up is they treat it like email blast: same template, business number, no rhythm, no specifics about the conversation they actually had. The homeowner immediately recognizes it as automated and disengages.

Three rules that separate cadences that work from cadences that get blocked:

1. Reference the actual conversation. Mention something specific from the door knock: their roof age, the south-facing panels, the EV in the driveway. Generic = ignored.
2. Send from your personal cell. The homeowner already has your number from the knock. Texts from that same number read as personal. Texts from an unfamiliar 800 number read as a tool blast.
3. Vary message length and tone. All-short, all-long, all-formal, or all-casual reads as a pattern. Mix it up the way a real human would.

The post-knock cadence (3 weeks, 5-6 touches)

This is the workhorse cadence for fresh leads who said "send me info" but did not commit to a specific next step.

Day 0 (same day, within 2 hours of the knock)

What this does: confirms identity, references something specific (the south exposure), sets expectations for the next contact. Do not pitch yet.

Day 2 (the value-add)

What this does: gives the homeowner something useful even if they never reply. The "no pressure" close lowers the bar to a yes.

Day 5 (the check-in)

What this does: gives the homeowner a graceful out (which often gets a "yes I am still interested, just busy" reply) without sounding salesy.

Day 10 (the light bump)

What this does: introduces a soft urgency (the federal credit) without being pushy. If the homeowner is going to convert, this is often the message that triggers the reply.

Day 20 (the final ask)

What this does: gives a clean exit. Many reps skip this message because it feels like giving up; in practice it gets a higher reply rate than message 4 or 5 because the homeowner feels obligated to respond to a clear close-out.

The post-appointment cadence (shorter, higher intent)

If the homeowner sat through a pitch, the cadence is different: 3 touches over 8 days, focused on closing the proposal that was already presented.

The post-quote cadence (very short, decision-driven)

If the homeowner has the proposal in hand, the cadence is even tighter: 2 touches over 5 days, framed around removing whatever specific thing is blocking the decision.

• Day 1: "Wanted to make sure you got the proposal. Any specific numbers you want me to walk through?"
• Day 5: "Hey [Name], saw the proposal hasn't been signed yet. Anything you want me to adjust, or are you just thinking it over?"

After day 5 with no response on a sent quote, do not keep pushing. Move to the 30-45 day nurture cadence. The lead is not gone, but pressure here will kill it.

The nurture cadence (long-term, low-frequency)

Leads that did not convert in the active cadence go here. One message every 30-45 days. The goal is staying top-of-mind, not closing.

Examples that work:

• Seasonal: "Hey [Name], heads up your summer bills are about to hit - if you ever want to revisit the solar numbers, the federal credit is still in effect through year-end."
• News-driven: "[Name] - utility just announced a 7% rate hike. Wanted to flag in case it changes your math on solar. No pressure, just wanted you to have the info."
• Direct check-in: "Hi [Name], just checking back in. Anything change on your end? Happy to send a fresh estimate any time."

After 6 months of nurture with zero engagement, archive the lead. Do not keep the cadence running indefinitely - eventually it crosses the line from helpful to annoying.

Timing: when to actually send

Conversion-optimal send windows in the recipient's local timezone:

• 11am-1pm: lunch break, phones get checked
• 5pm-7pm: post-work, pre-dinner, peak attention

Avoid:

• Before 9am or after 8pm (TCPA quiet hours start at 9pm in most states; play it safe with 8pm)
• Weekends, unless the homeowner explicitly said "weekends are easier"
• 2pm-4pm (deadest reply window in the data)

TCPA, opt-outs, and the legal stuff

SMS follow-up is regulated. The high points:

• Quiet hours: do not text between 9pm and 8am in the recipient's timezone, full stop
• Opt-outs: any STOP, UNSUBSCRIBE, or "do not contact" message means immediate DNC, no exceptions
• Consent: the door knock conversation usually counts as express consent, but document it (note in CRM, time/date)
• FTA exemption (Florida only): if you are setting an appointment (not closing), Florida's appointment-setting exemption applies; other states do not have this

What about ringless voicemail?

Ringless voicemail (RVM) drops work as a complement to the SMS cadence, not a replacement. The play that works in 2026:

• Use RVM at day 5 or day 10 when SMS engagement has cooled
• Keep the voice message under 20 seconds
• Sound natural ("Hey [Name], it's [Rep], just thought of you, wanted to see if you had any questions on the solar stuff. Give me a shout when you have a minute.")
• Follow the RVM with an SMS the next morning referencing it ("Left you a voicemail yesterday - just wanted to check in.")

RVM has higher trust signal than SMS but lower scale. Use it strategically on the leads worth re-engaging, not as a default touch on every cadence.

Tooling: doing this manually does not scale

Running the cadence above for 1-2 leads a week, you can do by hand. Running it for 10-20 fresh leads a week (a typical residential solar rep) and you will start dropping touches, mistiming sends, and forgetting which lead is on which day.

This is the job FollowUp is built for: solar reps install the iOS app, the cadence runs from their personal iPhone via iMessage (so the homeowner sees the rep's actual number, not a business line), and AI reads every reply so the rep only opens the app when a homeowner replies with intent. Free tier covers a typical day on the doors.

Frequently asked questions

How often should solar reps follow up with leads via SMS?

For a fresh post-knock lead, the cadence that works in 2026 is: same-day reminder, day 2 value-add, day 5 check-in, day 10 light bump, day 20 final ask. After day 20 with no response, move the lead to a long-term nurture cadence (one message every 30-45 days) rather than continuing to push. Total of 5-6 active touches over 3 weeks.

What time of day should solar reps send follow-up texts?

Best response windows are 11am-1pm (lunch break) and 5pm-7pm (post-work, pre-dinner) in the recipient's local timezone. Avoid before 9am, after 8pm, and weekends unless the homeowner explicitly opted in to weekend contact. TCPA quiet hours (8pm-8am local) are legally required, but the conversion-optimal windows are tighter than that.

Should solar SMS follow-ups come from a business number or personal cell?

Personal cell, every time. The homeowner already has the rep's number from the door knock; texts from that same number read as personal and reply rates are 2-3x higher than texts from a business line they do not recognize. The exception is teams using a shared inbound line for compliance reasons; in that case, lead with the rep's name in the first message.

When should a solar rep stop following up?

After 5-6 active touches with no response, move the lead to a 30-45 day nurture cadence rather than continuing weekly contact. After two STOP responses or any "do not contact" indication, mark the lead DNC immediately. After 6 months of nurture with no engagement, archive.

What about ringless voicemail for solar follow-up?

Ringless voicemail (RVM) drops work as a complement to SMS, not a replacement. Use RVM at the day 5 or day 10 touch when SMS engagement has cooled, with a short 20-second voice message that sounds like the rep just thought of the homeowner. RVM has higher trust signal than SMS but lower scale; use it strategically, not for every touch.
