A solar installer signs a new appointment vendor after a strong sales call. The first batch lands: half the homeowners do not remember booking anything, one address sits outside the service area, and the "confirmed" consultation was set by a rep who never mentioned solar at all. The invoice still says paid in full.
That outcome is common enough to be the default when installers buy on price alone and skip due diligence. An exclusive consultation and a shared lead dressed up as an appointment can carry the exact same price tag on an invoice, and nothing on a sales call tells you which one you are actually buying.
This post lays out four things to verify before you commit real budget to a new vendor: proof of consent, an exclusivity clause you can point to in writing, a refund and replacement policy for no-shows, and a small paid pilot before you scale. Each one closes a specific way installers get burned.
Why Solar Buyers Have Less Room for Vendor Error
Solar has a narrower margin for vendor mistakes than most home-services categories. Installers spend an average of about $1,400 in total lead costs to close a single job nationally, and that figure swings from roughly $500 in competitive, lower-cost markets like Texas and Florida up to about $2,000 in California and Massachusetts. A vendor's flat per-appointment price does not tell you where your market sits on that range, and a bad batch does not just waste a few hundred dollars, it eats directly into a budget that is already thin against how few leads actually close.
That close rate is thin to begin with. Real-time solar leads convert somewhere between 3% and 10%, and lead-to-close rates across the industry run around 8% to 12%, by industry estimates. Roughly 80% of closed solar deals reportedly need the fifth through twelfth touch to land, by industry estimates, which means a homeowner who was contacted once and dropped costs you the entire funnel built around that name, not just a single call.
Timing compounds it. Homeowner interest in a solar consultation tends to fade within 48 to 72 hours if nobody confirms it quickly, by industry estimates. A vendor that takes a week to hand off a "hot" appointment is handing off a cold one wearing a warm label, and you are still paying the hot-lead price for it.
The Four Things to Verify Before You Commit Real Budget
None of these require a lawyer or a background check. They are questions a vendor with a real operation can answer in writing, before you pay for a single appointment.
1. Consent Documentation
Ask exactly how the homeowner consented to be contacted, and get it in writing. Since January 27, 2025, an FCC rule has required that a homeowner's written consent to be called or texted apply to a single identified seller, and be logically related to what they actually searched for or requested. That rule closed the loophole that let one blanket consent form get attached to a lead resold to dozens of unrelated companies across different industries.
If a vendor cannot show you when and how a specific homeowner agreed to hear from a solar company, and only a solar company, that appointment does not meet the current legal standard, and the exposure for using it does not stay with the vendor. TCPA violations carry statutory damages of $500 per violation, rising to $1,500 if a court finds it willful, and that liability can attach to the business that made the call, not only the list seller.
Ask for the consent record itself, not a description of it: the date, the source page or call, and the specific disclosure language the homeowner agreed to. A vendor that treats this as a formality instead of a document you can review is telling you something about how the rest of the relationship will go.
2. An Exclusivity Clause You Can Point To
Exclusive solar leads run roughly three times the price of shared leads industry-wide, by industry estimates, and that premium exists because exclusivity changes the outcome, not just the invoice. A shared lead gets worked by whichever installer dials back first, and speed alone decides who gets the appointment, regardless of who is actually the best fit for that homeowner's roof, shading, and budget.
"Exclusive" on a landing page is marketing copy. Exclusive in a contract is a specific sentence: this appointment is sold to you and only you, it will not be resold or repackaged to another installer, and here is what you are owed if that turns out to be false. If a vendor cannot produce that sentence, or hedges when you ask for it directly, price the deal as shared, regardless of what the invoice calls it.
Some vendors do publish real, checkable numbers. ResultCalls advertises exclusive solar pay-per-call appointments at $24.85 to $29.85 per call on its own site, a live, dated price you can verify today. Whatever you are quoted, ask why it sits above or below a number you can already check independently, and treat a refusal to explain the gap as a red flag on its own.
3. Refund and Replacement Terms for No-Shows
A no-show policy is worth nothing until it is written down as a rule with a deadline attached: what counts as a no-show, how long you have to report it, and what you get instead of a wasted appointment slot, a free replacement or a credit, not an apology. Some solar appointment vendors market guaranteed appointments or money-back promises, but a marketing claim is not a contract term you can hold anyone to. Get the actual mechanics: the reporting window, who decides a disputed no-show, and whether the remedy is a replacement appointment or a refund.
Push for specifics on what "qualified" meant for that homeowner before the vendor booked the slot: confirmed homeownership, a workable roof, and a decision-maker who will actually be in the room. A no-show tied to bad qualification, a renter, a heavily shaded roof, someone who never agreed to the appointment, is not really a no-show. It is a lead that should never have been booked, and the remedy should reflect that, not just the standard no-show credit.
4. A Small Paid Pilot Before You Scale
Run a small, paid batch before committing to full monthly volume. As a practical rule of thumb, ten to fifteen appointments is usually enough to see a real pattern. Track two numbers against what the vendor promised at the sales call: how many homeowners actually showed, and how many who did show actually matched the qualification criteria you gave the vendor at kickoff.
A vendor with a real operation will agree to this without resistance, because they already know their own numbers. A vendor that insists on a large minimum order or a long contract before you have seen a single batch of results is asking you to underwrite their unproven claims with your own budget, not the other way around.
Compare the pilot batch against the regional benchmark, not just against the vendor's pitch. If national data puts average lead spend around $1,400 per closed job, and your pilot batch is already tracking well outside that range once you count no-shows and bad qualifications, that is a signal to renegotiate or walk, before a bad vendor becomes a habit.
What the Same Vendor Price Actually Means, by Market
A vendor quoting a flat per-appointment rate is quoting the same number nationwide, but the market underneath that number is not flat. Published state-level data on total lead spend to close one job shows how much that varies by region:
| Market | Avg. total lead spend per closed job |
|---|---|
| National average | About $1,400 |
| Texas, Florida (lower-cost, competitive markets) | About $500 |
| California, Massachusetts (higher-cost markets) | About $2,000 |
Figures are SolarReviews' published state-level averages for total lead spend per closed sale, not a single vendor's per-appointment price. Use them as a sanity check on a vendor's quote relative to your own market, not as a price you should expect any vendor to charge directly.
A Vendor Scorecard: Red Flag vs. What a Real Vendor Commits To
Strip away the marketing language and a clean solar appointment contract answers each of the four questions above without you having to ask twice.
| Contract term | Red-flag version | What a real vendor commits to |
|---|---|---|
| Consent documentation | "Trust us, it's compliant" | A dated consent record tied to a single seller, available on request |
| Exclusivity | "High-intent leads," no statement on resale | Written statement: sold to you only, never resold |
| No-show handling | Silent, or "quality is not guaranteed" | Defined reporting window and a stated remedy, replacement or credit |
| Qualification standard | Vague "homeowner interested in solar" | Written criteria, homeownership, roof and shade fit, bill range, decision-maker, agreed before launch |
| Contract length | Large minimum or long lock-in before you've seen results | A small paid pilot batch available before any volume commitment |
| Pricing | Custom quote with no benchmark to compare against | A rate you can weigh against your own region's cost-per-close data |
What this means for you
- Get consent documentation, an exclusivity clause, and a no-show remedy in writing before you pay, not implied in a sales deck.
- Treat a vendor's willingness to start with a small paid pilot as a signal. Resistance to a pilot is resistance to being measured.
- Compare a vendor's quote against your own region's cost-per-close data, not just against their pitch.
