Solar installer leads: the hole is between signature and install

The bottleneck: everything between signature and install

The signature is not the finish line. What follows is a sequence of steps mostly outside the contractor's control, and each one is a place where a signed customer disappears:

1. Credit and financing approval. The largest single cause of cancellation. Approving before design work begins saves enormous wasted effort.
2. Site survey and structural review. Roof age, condition, framing capacity and electrical panel adequacy. Any of these can change or kill the project.
3. Design and engineering. Shading, orientation, production modeling and the final system size — which may be smaller than what was sold.
4. Permitting. Timeline varies from days to months by jurisdiction.
5. Utility interconnection application. Approval to connect, on the utility's timeline.
6. Installation.
7. Inspection and permission to operate. The system cannot legally produce until this arrives, and it frequently takes weeks after installation.

The customer experiences this as: signed a contract, then nothing happened for two months. The single highest-return operational fix in residential solar is a communication cadence during this dead period — a status update every week, even when the update is that nothing changed. Companies that do this see cancellation rates drop by a third or more.

Selling without promising numbers you do not control

Solar has a reputation problem, and it was earned by overpromised savings. The contractor who wants a durable business has to sell honestly in a market where competitors do not — and that is more workable than it sounds, because homeowners have already heard the exaggerations and are wary.

Four rules:

Model production as a range, not a figure. Base it on twelve months of the customer's actual usage, real shading analysis and conservative assumptions. Present a low case, an expected case and note the variables.

Never state incentive amounts as certainty. Federal, state and utility programs change, have eligibility conditions and depend on the customer's own tax situation. Explain that programs exist, point to where the current rules are published, and tell the customer to confirm eligibility with their tax professional. Putting a specific dollar figure in a sales pitch is how companies end up in disputes.

Be explicit about the roof. If the roof has fewer than seven to ten years of life left, say so, and quote the removal and reinstall cost the customer will face later — $6,000 to $12,000 in many markets. Recommending a roof replacement first costs you a fast sale and earns a customer who trusts you.

Explain interconnection and rate structure plainly. How excess production is credited, whether rates are time-of-use, and what the utility's rules are. This is where actual savings are determined, and it is the part most sales presentations skip.

Building the referral engine that solar companies talk about and never build

Every installer says referrals are their best source. Very few treat them as a channel with a budget, a process and a target — which is why most companies get referrals passively and at a fraction of the volume the channel can produce.

A referral system that actually works has five parts:

• A trigger with a date. The best moment is not at signing and not at install. It is roughly 30 to 45 days after permission to operate, when the customer has seen their first meaningful bill and the enthusiasm is grounded in something real. Put that date in the calendar at install, and make the contact a real conversation rather than an automated message.
• Something specific to ask for. "Let us know if anyone asks" produces nothing. "Is there someone on your street who has asked you about the panels?" produces a name, because neighbors always ask.
• A reward that is legal and disclosed. Referral compensation is regulated in some states and in some financing programs, and structures that are fine in one place are not in another. Check the rules for your state and for the lenders you use, then say plainly in writing what the customer gets and when.
• Something the customer can hand over. Their actual production data, shared with permission, is more persuasive than any brochure — a neighbor with the same roof orientation seeing real numbers from the house down the street is the strongest proof available.
• Fast handling of the referred lead. A referral treated like a purchased lead — three days to first contact, generic script — burns the relationship with the referring customer as well as the prospect.

The economics justify real investment here. If a purchased-lead channel costs $1,900 per installed system and a structured referral program costs $400 in reward and coordination, moving ten installs a year from one to the other is worth $15,000 in gross profit — before counting the higher close rate and lower cancellation that referred customers bring.

One month, with the leaks visible

A regional installer with two crews. Average system $27,400, gross margin 24%, so $6,576 of gross profit per install.

Leads received: 240, from purchased leads, paid social, referrals and organic search. Marketing and lead cost: $31,000.

• 84 became appointments
• 23 signed contracts
• 16 were installed

Revenue: $438,400. Gross profit: $105,216. Cost per installed system: $1,938.

Now the seven contracts that did not become installations: 3 were denied financing after design work had begun, 2 had roofs that failed structural review, and 2 cancelled during a long permitting wait with no communication. That is $46,032 of gross profit signed and lost, plus the design and coordination hours spent on all seven.

Three changes: pre-qualify financing before any design work, add a roof-age question to the first call and a structural check to the site survey before contract, and send a weekly status message during the permitting period. The same 240 leads then produce 21 installs — $575,400 in revenue and $138,096 in gross profit.

That is $32,880 more gross profit per month, and the cost per installed system falls from $1,938 to $1,476 — a 24% improvement bought entirely with process, not with advertising.

An offer that passes the swap test

The bill-based proposal. "Send us twelve months of bills and we will send you a design and a range within two business days — before anyone visits your house." It respects the customer's time, filters the unserious, and is the opposite of the high-pressure appointment the market expects.

The roof-first commitment. "If your roof has less than a decade left, we will tell you and recommend replacing it first, even though it delays our sale." Nobody else says this, and every homeowner has heard the horror story.

The weekly update promise. "From the day you sign until the day your system is turned on, you get an update every Friday — including the Fridays when nothing moved." It directly attacks the industry's worst customer experience.

Five mistakes that cost solar installs

• Designing before financing is approved. Engineering hours spent on a customer who cannot fund the project are pure loss.
• Quoting incentives as guaranteed dollars. Programs and eligibility change, and the promise becomes a dispute.
• Ignoring roof condition to protect a sale. It produces the most expensive callback in the industry.
• Going silent between signature and install. The single largest controllable cause of cancellation.
• Measuring cost per lead instead of cost per install. It leads companies to buy more cheap leads while the real problem sits downstream.

Five numbers to track

• Cost per installed system by source, which usually reorders your entire channel mix.
• Cancellation rate between signature and install, with reasons categorized.
• Days from signature to permission to operate, broken into stages.
• Referral installs as a share of total, tracked deliberately.
• Gross profit per install, not average system price.

Solar is a business where the marketing budget gets blamed for problems that live in operations. The install rate between signature and turn-on is where most companies quietly lose a fifth of everything they sold — and it is the cheapest thing on this list to fix.

Frequently asked questions

What is a normal conversion rate for solar leads?

Far lower than in other trades, and it compounds across three stages. Leads to appointments typically runs 25% to 45%, appointments to signed contracts 20% to 35%, and signed contracts to installed systems 65% to 85%. Multiplied through, a typical funnel converts only 4% to 12% of leads into installed systems. The third stage is what makes solar structurally different: you can sign a customer and still never get paid, because financing is denied, the roof fails structural review, the shading analysis changes the design, or the customer cancels during a long permitting wait. This is why cost per lead and cost per appointment are nearly meaningless here, and why the only number that runs the business is cost per installed system measured against gross profit per install.

Why do solar customers cancel after signing?

Four reasons account for most of it, and three are preventable. Financing denial is the largest, and it is avoidable by approving credit before any design work begins. Roof condition and structural review failures come next, and a roof-age question on the first call plus a structural check before contract catches nearly all of them. Long permitting and interconnection waits produce the third group: the customer experiences signing a contract and then nothing happening for two months, and concludes the company is not competent. That one is fixed by a weekly status message during the dead period, even when the update is that nothing changed — companies that do this see cancellation drop by a third or more. The fourth is design changes that shrink the system after sale, which honest modeling up front largely prevents.

How should solar companies talk about savings and incentives?

Carefully, because the industry's reputation problem was earned by overpromising and homeowners are already wary. Model production as a range rather than a single figure, based on twelve months of the customer's actual usage, real shading analysis and conservative assumptions, presenting a low case and an expected case with the variables named. Never state incentive amounts as certainties: federal, state and utility programs change, carry eligibility conditions and depend on the customer's own tax situation, so the correct approach is to explain that programs exist, point to where current rules are published and tell the customer to confirm eligibility with their tax professional. And explain interconnection and rate structure plainly, since how excess production is credited and whether rates are time-of-use is where actual savings are determined.

What should a solar company do about a customer's old roof?

Say so, and quote what the customer will face later. A roof with fewer than seven to ten years of life remaining will need replacing while panels are on it, and removing and reinstalling a residential array costs roughly $6,000 to $12,000 in many markets. Recommending a roof replacement first costs a fast sale and produces the most expensive callback in the industry when ignored. It also happens to be a strong commercial position: every homeowner has heard the story of someone who had to pay twice, so a company that volunteers the problem before the sale is immediately more credible than one that avoids it. The practical implementation is a roof-age question on the first call and a structural condition check during the site survey, before a contract is signed rather than after.

How do you build a solar referral program that actually produces?

With five parts, and a date is the first of them. The best moment to ask is not at signing or at install but roughly 30 to 45 days after permission to operate, when the customer has seen a real bill — put that date in the calendar at install and make it a conversation, not an automated message. Ask for something specific: not let us know if anyone asks, but is there someone on your street who has asked you about the panels, because neighbors always ask. Offer a reward that is legal and disclosed, checking your state's rules and your lenders' requirements first. Give the customer something to hand over, ideally their own production data shared with permission. And handle referred leads fast, because treating one like a purchased lead burns two relationships at once.
