Solar lead follow-up: the 3/10/30/90 cadence that recovers 25-40% of silent quotes

Solar lead follow-up is one of the most expensive operational gaps in residential solar. A typical $26,000-$48,000 system quote represents weeks of pipeline work, scanifly or aurora design output, financing pre-qualification, and proposal preparation. When that quote goes silent, most installers either spam the homeowner with daily messages or abandon the lead entirely. Both responses lose money. The 3/10/30/90 cadence recovers 25-40% of silent quotes into booked installs, often months after the original conversation. This is the playbook.

Why solar quotes go silent

Three structural reasons solar prospects don't immediately sign. Each requires a different response from your follow-up sequence.

The decision is bigger than they expected

Most homeowners researching solar haven't run the numbers carefully. They get a $34,000 quote and freeze, even when financing makes the monthly payment lower than their current utility bill. The price shock takes 1-3 weeks to absorb. Aggressive followup during that window pushes them away.

They're collecting other quotes

Roughly 70-85% of residential solar prospects collect 2-4 quotes before signing. The decision-cycle median is 4-9 weeks for residential. Your quote going cold doesn't mean lost. It usually means they're still shopping, often comparing your soft costs against EnergySage marketplace bids or against a national installer's lower headline price.

The 25D federal tax credit expired in late 2025

If you sold solar before 2026, you remember the 30% federal tax credit baked into every proposal. That changed January 1, 2026 with the One Big Beautiful Bill Act phasing out 25D for residential cash and loan customers. The customer's economics shifted. Many of them know this and are now genuinely uncertain whether the math still works for them. Your follow-up sequence has to address the math, not just nag.

The 3/10/30/90 cadence

Each touchpoint serves a specific purpose, with messaging calibrated to the stage of the buyer's decision cycle.

Day 3: The thoughtful first followup

A short text or email from the rep who delivered the proposal. Not a generic mass-blast. Personal, specific, brief.

Sample SMS: "Hi [name], it's Mike from Solar AI Employee. Wanted to follow up on the proposal I sent Monday. Any questions about the financing options or the production estimate? Happy to walk through it whenever works for you."

Why this works: you're showing up early enough to be helpful, not late enough to feel pushy. The mention of two specific elements (financing, production estimate) signals you remember their specific situation and invites a substantive question rather than a yes/no response.

Day 10: The objection-surfacing followup

If they didn't respond to day 3, send a more direct followup that explicitly surfaces the most likely objections.

Sample email: "Hi [name], wanted to check in once more on the solar proposal. Most homeowners I talk to at this point are weighing one of three things: the math without the federal credit, comparing against another quote, or timing for the install. Happy to address any of these. Just let me know which one is on your mind."

Why this works: in 2026, the post-25D math is the elephant in the room for most residential prospects. Naming it explicitly shows you're not pretending the credit still exists. The framing invites a real conversation about the new math instead of a polite avoidance.

Day 30: The market-update or new-information followup

By day 30, the original proposal is fading from memory. Don't send another "following up" message. Share something genuinely useful that changes their decision context.

Examples that work in 2026:

Utility rate change. If your utility filed a rate increase or a TOU restructure, send a brief note explaining what it means for solar economics. "Our utility just filed for a 6.4% rate increase effective July 1. For your home that's roughly $44/month more. Solar economics shift quite a bit. Want me to send updated numbers?"

State or local incentive. Many states have rebate programs that update quarterly. If your state's program changed, surface it.

48E TPO option. If your shop offers third-party-owned solar (where the 48E commercial credit flows through to lower customer pricing), and your prospect was a cash/loan customer, surface this as an alternative path.

Why this works: you're showing up as an advisor, not a salesperson. The information is real and useful. Customers who were stalled often re-engage at this touchpoint because you've changed their decision context.

Day 90: The graceful close or revival

By day 90, you're either out of contention or in a long-cycle reconsideration. The day 90 message offers an off-ramp.

Sample SMS: "Hi [name], it's been a couple months since we talked about solar. I want to respect your time. If you've gone with another option or now isn't right, no worries at all. Reply 'remove' if you'd like off our list. Otherwise I'll check back next quarter."

Why this works: high-class exit. Some homeowners reply now precisely because the pressure is off. Others come back 6-9 months later when life settles, the panel they were considering becomes available, or their utility rates spike enough that the math shifts.

What conversion rates to expect

Across well-run residential solar operations using this cadence in 2026:

Day 3 response rate: roughly 30-45% of cold quotes. Most are clarifying questions or scheduling discussions, not immediate closes.

Day 10 response rate: roughly 12-22% additional. The post-25D objection-surfacing is what triggers responses here.

Day 30 response rate: roughly 8-18% additional. The market-update touchpoint often surfaces homeowners who were genuinely stalled and needed new information.

Day 90 response rate: roughly 4-10% additional, plus a smaller stream of revivals 4-9 months later.

Cumulative recovery rate: 25-40% of cold quotes turn into booked installs over 12 months. Median time from cold to signed contract: 58 days.

What kills the recovery rate

Three patterns that consistently destroy conversion in solar shops trying to implement this cadence.

Generic followup from a non-rep alias

Messages from "sales" or "the team" get ignored at 2-3x the rate of messages from a named human. Every touchpoint should come from the rep who originally delivered the proposal, with a personal signature. The relationship continuity is what makes the homeowner respond at all.

No reference to specific proposal details

"Just following up on your solar quote" is generic. "Just following up on the 7.2 kW system with the SunPower panels we proposed" is specific. The specificity signals real attention, not mass blast. Most CRMs let you template fields like system size, panel brand, financing option into followup messages.

Daily or every-other-day cadence

Pushing too frequently triggers blocking, unsubscribing, and 1-star reviews. The 3/10/30/90 deceleration is deliberate. Solar decision cycles are long; pacing patience is what's actually required.

Common questions about solar followup cadence

What if the homeowner explicitly says "not interested"?

Mark the lead permanently lost in your CRM and stop the cadence. Don't try to recover. The unsubscribe-disrespect cost is higher than any revenue you'd recover from the small fraction who change their mind after explicit refusal.

How do we handle homeowners who reply but say "not now"?

Tag them with the stated reason (price, timing, comparing quotes, life event) and the appropriate next-touch date. "Not now" is information, not a no. Many of these homeowners book in 6-12 months when their context shifts. Right followup at the right re-engagement date is the difference between a lost lead and a recovered one.

Should the cadence change for high-dollar systems vs lower-dollar systems?

For sub-$15,000 systems (small residential, partial-array installs): compress to 2/7/21/60. For $15,000-$40,000 standard residential: use the full 3/10/30/90. For $40,000+ luxury or commercial-residential hybrid: extend to 5/14/45/120. Larger decisions need more patience.

Can AI handle this followup?

For day 3 and day 10 touchpoints, automated SMS/email from your CRM handles it well as long as templates allow personalization fields for system specs and financing details. For day 30 (market-update) and day 90 (graceful close), most shops keep these as human-sent because the content benefits from real-time market judgment. AI can draft, human approves and sends.

What about the specific case of a referral lead vs a cold lead?

Compress the cadence for referrals: 2/7/21/60. The trust capital from the referral source means the homeowner is more receptive earlier. Stretching the cadence on a referral risks them losing momentum or moving forward with someone else who responds faster.

What to do this week

Pull every solar proposal your shop sent in the last 90 days that didn't sign. Sort by system size descending. For the top 20 by size, run the day 30 market-update touchpoint manually this week. Mention the post-25D math, your utility's recent rate filings, or 48E TPO options if applicable.

Track responses and bookings over the next 60 days. If your recovery rate hits even half of the 25-40% benchmark from the math above, that's substantial revenue from leads you'd otherwise have lost.

If your sales team is buried with current proposals and can't run a disciplined followup cadence, our AI lead followup handles the cadence in the background, surfacing replies and re-engagements to your reps as they come in. The system pauses automatically when a customer replies so you don't accidentally send the day 90 close to someone who already booked.
