"Qualified" is the word every appointment vendor uses to sell a meeting. It also means nothing until someone writes down what it takes to earn that label. A homeowner who replies "yes, tell me more about solar" to a text is not automatically someone who can sign a contract, pass underwriting, or put panels on a roof that will hold them for the next 25 years.
That gap is where installers lose money. A rep drives out, runs a full site visit and financing conversation, and finds out thirty minutes in that the homeowner rents the property, has a roof that needs replacing first, or cannot clear a basic credit floor with any lender licensed in the state. The appointment got booked. It was never qualified.
This is the checklist we hold every solar appointment to before it lands on a client's calendar: seven property, financial, and authority checks that separate a real consultation from a wasted afternoon. Use it to build your own vendor standard, whether you work with us or with somebody else.
The problem with a vague "qualified" appointment
Every appointment vendor will tell you their leads are qualified. Almost none of them will tell you against what standard. That is not an accident. A vague definition lets a vendor count a homeowner who merely answered a text as "qualified," bill you for the appointment, and move on before you find out the roof needs a full replacement before solar makes sense on top of it.
The stakes are real money, not just a wasted morning. Exclusive, vetted appointments already cost more to generate than a shared marketplace lead, roughly three times as much by industry estimates, because building a real one-to-one conversation with a homeowner who actually fits your criteria takes work a shared list does not. If that premium buys you the same tire-kicker a cheap shared lead would have gotten you, you paid three times more for nothing. See how that math plays out on exclusive appointments versus shared solar leads.
A written standard fixes this. It turns "qualified" from a marketing adjective into a checklist your vendor has to hit, appointment by appointment, before you agree to pay for it.
The 7-point homeowner checklist
These are the checks we run, in some order, before a solar appointment is considered bookable. None of them guarantee a close. Together, they filter out the appointments that were never going anywhere.
| # | Criterion | Disqualifying threshold | Why it matters |
|---|---|---|---|
| 1 | Homeownership / title | Renter, or cannot confirm title | Only an owner or title holder can sign a solar contract or loan |
| 2 | Roof age | Under 15 years of remaining life | Installer risks a warranty problem, or the homeowner needs a new roof first |
| 3 | Monthly electric bill | Under $80 to $100 (higher in low-rate states) | Below that floor, system size rarely justifies the sales cycle |
| 4 | Credit range | Below roughly 600 FICO | Most solar lenders will not approve financing under that floor |
| 5 | Shading exposure | Above 30% annual shading | Production loss makes system economics fall apart |
| 6 | HOA / permitting | Unconfirmed HOA restrictions on panels | Can kill a signed deal after the site visit instead of before it |
| 7 | Decision authority / DTI | No decision-maker present, or debt-to-income near 50% | Nobody able to approve financing is in the room, or they will not qualify |
1. Homeownership and title
Renters cannot approve a solar installation. Only the owner, or in some cases another name on the title, can sign the contract that finances a system bolted to the roof. That sounds obvious, but self-reported ownership on a cold-outreach list runs only about 85 to 90% accurate, according to solar lead-qualification data. That means roughly one in ten "homeowner" leads is not actually the person who can sign. A real qualification step confirms the name on record against title or a recent mortgage or property tax document before the appointment lands on a rep's calendar.
2. Roof age under 15 years
The working rule most solar lead-qualification frameworks use is at least 15 years of remaining roof life. Lead-gen qualification research puts asphalt shingle roofs at 12 to 15 years of remaining life once they qualify, architectural shingle and wood shake roofs at 15 to 20 years, and flat roofing at 10 to 15 years. Below the threshold for the material, the appointment is a coin flip: either the homeowner has to replace the roof first, which usually kills the deal, or the installer inherits a warranty problem down the line.
3. Monthly electric bill floor
Below $80 to $100 a month, the math rarely works. The system size a low bill justifies is too small to carry the sales cycle and installation cost, and that range is the floor cited in solar sales pre-qualification standards. Local electricity rates shift the number: qualification research recommends a floor closer to $175 to $200 or more in low-rate states like Texas and Georgia, versus $100 or so in high-rate markets like Hawaii or California, because the same system saves a Texas homeowner less than it saves someone paying California rates.
4. Credit score in the 600 to 650 FICO range
Most solar financing programs set a floor around 600 FICO, and premium programs with the best rates often want 680 or higher. Sunlight Financial, one of the larger solar lenders, sets 650 FICO as the minimum for a standard loan and reserves its best annual percentage rate tiers for borrowers above 700. A vendor that cannot tell you what credit range it screens for is not actually qualifying anyone on financing, it is just hoping.
5. Shading exposure under 30%
Panels lose production to shade on a predictable curve. Solar lead-qualification benchmarks put 0 to 5% annual shading as minimal impact, 5 to 15% as a light reduction, 15 to 30% as a moderate hit, and anything above 30% as heavy, the point where system economics get genuinely difficult and conversion drops sharply. A roof with a mature tree over half of it might still belong to a homeowner who wants solar. It should not eat up a rep's afternoon until someone runs a shading estimate first.
6. HOA and permitting clearance
A homeowner in an HOA-controlled community can want solar and still get denied by the architectural review board after the fact. That kills a signed deal after the site visit instead of before it, which is the worst place for a disqualifier to surface. A real qualification standard asks about HOA status and any known panel restrictions as part of the intake conversation, not as a surprise the rep discovers on-site.
7. Debt-to-income and a real decision-maker
Financing a system in the tens of thousands of dollars runs through the same underwriting logic as any other consumer loan. Sunlight Financial caps debt-to-income near 50%, with some capital providers applying a tighter 45% overlay once the new solar payment is layered onto the homeowner's mortgage, auto loans, and credit card minimums. On top of the math, whoever's name is on the utility bill and title needs to actually be present, in person or on the call. A spouse who "will run it by" the decision-maker later is not a qualified appointment. It is a maybe.
Put the checklist in writing
A checklist only works if it is part of the contract, not a conversation you had once during onboarding. Before a vendor books a single appointment, get these seven criteria into the statement of work in writing, along with what happens when an appointment misses one of them. The answer should always be: replaced free, not billed as delivered.
That is the same discipline covered in how to buy solar appointments without getting burned: a small paid pilot batch, a documented qualification standard, and a replacement clause before you commit real budget to volume. Ask for the actual intake script or form the vendor uses to check these boxes. If nobody can produce one, nobody is checking anything. They are booking whoever answers.
What an unqualified appointment looks like
Watch for these signs before you agree to pay for an appointment, and especially before you scale volume with a new vendor:
- The homeowner is a renter or cannot confirm they are on the title.
- Nobody asked about the roof's age or condition before booking the slot.
- The stated monthly bill is below $80 to $100 and nobody flagged it.
- No credit range was discussed, or the vendor "does not ask about that."
- The homeowner mentioned an HOA and nobody checked for panel restrictions.
- The person on the call cannot approve financing alone and needs to check with someone who is not there.
- The appointment was booked same-day with no confirmation call or text before the slot.
What this means for you
If you are buying solar appointments today, do not accept "qualified" as a description on its own. Ask for the standard in writing, ask how each of the seven checks gets verified, and ask what happens when one fails after the appointment is already on the calendar. A vendor with a real process has ready answers. One that goes quiet is telling you something.
When we build a solar appointment campaign, we lock in a client's specific criteria first: credit floor, bill minimum, roof age window, service area, before a single message goes out, and every appointment gets checked against that standard before it reaches the calendar. See how the process works or how pricing works for the rest of the model, or book a short call and we will walk through your specific criteria.
