How the Shared Lead Model Actually Works
A shared-lead broker runs ads (Facebook, Google, comparison sites in the EnergySage mold) promising homeowners "free solar quotes." A homeowner fills out one form. The broker then sells that single form submission to multiple installers in the same territory, often three to five of them, sometimes more if the market is thin. Everyone gets the same name, phone number, address, and utility bill estimate at roughly the same time.
The broker's incentive is volume, not fit. They get paid whether or not you close the deal, so the quality control stops at "did someone fill out a form." That's why so many shared leads turn out to be renters, homeowners who filled out the form for a rebate estimate with no real intent, or people who already picked an installer three days ago and just haven't answered their phone since. None of that shows up in the broker's data. It shows up in your close rate.
The math that matters: if five installers get the same lead, and the homeowner only signs with one, four installers paid for a lead that produced zero revenue. Brokers know this and price accordingly, which is why shared leads look cheap per-unit but expensive per-close once you track it all the way to a signed contract instead of stopping at the initial form fill.
- Speed-to-lead becomes the whole game. Whoever calls first (often within minutes, using auto-dialers) gets the first conversation and the first shot at framing the decision.
- Price gets compared before value does, because the homeowner is mid-call with three other installers by the time you reach them, and every installer is pitching the same tax credit and the same payback period math.
- Your CRM fills up with contacts who never answer a second call, because they already booked with someone faster, which quietly inflates your cost-per-contact even when cost-per-lead looks fine.
- Follow-up sequences get longer and less effective, because a homeowner who already committed elsewhere has no reason to pick back up the phone for installer number four.
None of this makes shared leads worthless. It makes them a volume play that rewards installers with a fast, aggressive inside-sales process built around minute-one callbacks, not installers running a relationship-based, education-first close.
How Exclusive Leads Are Different (and Why They Cost More)
An exclusive lead means one thing: nobody else got that homeowner's contact information from the same source at the same time. That can come from a few places. Paid search campaigns built and run for your company alone (see our page on Google Ads for solar companies for how that works). Organic rankings on your own site, where the homeowner found you specifically and called or filled out your form. Or a lead-gen vendor that sells one-to-one instead of one-to-many, which costs more per lead because the vendor isn't reselling the same click five times over to recover its ad spend.
The price difference is real. Where a shared solar lead might run $30 to $60, an exclusive one commonly lands in the $80 to $200+ range depending on market competitiveness, system size targeted, and whether battery storage is part of the ask. That's not a markup for the same product. It's the cost of not splitting the homeowner's attention five ways, and it's priced closer to what the lead is actually worth once you account for who else is (or isn't) in the running.
What that buys you: a homeowner who is still forming their opinion of solar when they talk to you, instead of one who's already compared your price against four competitors before you've said hello. It buys you time in the sales process, which matters enormously for a purchase this size. A $25,000 decision with financing math, roof and shading questions, HOA rules, and a payback-period conversation does not get won in a single fast call. It gets won over multiple touches where trust builds instead of decays under competing sales pressure.
It also changes what your sales reps are actually doing on the call. On a shared lead, the first five minutes are a race to differentiate on price before the homeowner hangs up to take the next call. On an exclusive lead, the first five minutes can be spent asking about the roof, the utility bill, and what's actually driving the decision, because there's no competing installer on the other line forcing a rushed pitch.
| Factor | Shared Leads | Exclusive Leads |
|---|---|---|
| Typical cost per lead | $30 to $60 | $80 to $200+ |
| Installers competing for it | 3 to 5, often more | Just you |
| Speed-to-lead sensitivity | Extremely high | Lower, still matters |
| Best fit | High-volume inside sales teams | Trust-based, longer-cycle closers |
The Real Close-Rate Math Solar Installers Skip
Most solar companies track cost-per-lead and stop there. That number lies to you on shared leads. The number that actually predicts revenue is cost-per-closed-deal, and that requires tracking your close rate separately for shared versus exclusive sources for at least one full quarter.
Here's the arithmetic installers usually discover the hard way: if shared leads cost $45 and close at 3 to 5% (typical for a lead split five ways in a competitive market), your real cost to land one install lead is $900 to $1,500 in lead spend alone, before commission and install costs. If exclusive leads cost $150 and close at 12 to 20% (typical when you're the only installer in the conversation and can run a proper needs-based sales process), your real cost to land one is $750 to $1,250. The less expensive lead is often the more expensive close.
This isn't a universal rule. Some sales teams are built for speed and volume and genuinely out-execute the field on shared leads, calling within 90 seconds and closing on the first conversation. If that's your shop, shared leads can pencil out fine as one channel in the mix. The mistake is assuming cost-per-lead tells the whole story without ever running the closed-deal math.
- Pull your CRM data by source for the last 90 days if you have it. Shared vendor leads vs. website form fills vs. paid search vs. referrals.
- Compare close rate and average install size by source, not just lead cost.
- Factor in sales hours spent per source. Shared leads often eat more inside-sales time per closed deal because of the callback chase.
If you don't have 90 days of clean source data, that's a signal on its own: fix the tracking before adding more lead spend of any kind.
Why the ITC Deadline Changes This Calculation
The federal solar tax credit timeline puts pressure on every lead source at once, and that pressure cuts differently depending on whether the lead is shared or exclusive. When homeowners are racing a credit deadline, urgency goes up across the board, which means shared-lead competition gets even more aggressive. Five installers chasing the same homeowner under a deadline means five installers all leaning on urgency, and the homeowner tunes out because it starts to sound like a sales tactic instead of a fact.
An exclusive lead lets you be the one credible voice explaining the actual timeline and the actual math, without a chorus of competing installers muddying the message with their own urgency pitch. That credibility gap widens further when the conversation shifts to battery storage, financing structures, or payback-period comparisons, all of which take more than one phone call to work through properly. A homeowner fielding five deadline pitches in one afternoon learns to distrust all five, including yours.
Practical takeaway: if you're running shared leads during a deadline-driven surge period, expect your close rate to dip further than usual, not improve, because homeowner skepticism toward pushy sales calls rises exactly when installers are leaning hardest on urgency. Exclusive-channel leads (organic, paid search, referral) hold up better under that same pressure because the homeowner isn't fielding four other calls making the same claim on the same afternoon.
There's a second-order effect worth planning around too. Deadline surges compress the calendar for install crews as much as for sales. A flood of shared leads that all need to close and get scheduled in the same narrow window can overload installation capacity in a way that a steadier, owned-channel pipeline doesn't. Spacing demand more evenly across the year, rather than living or dying on deadline spikes, is one underrated argument for building exclusive channels you control instead of renting shared-lead volume that surges and dries up on the same calendar every buyer is watching.
This is also where solar lead generation built around your own site and search visibility earns its keep over the long run: it's not vulnerable to a deadline-driven spike in shared-lead competition the way bought leads are.
When Shared Leads Still Make Sense
We're not going to tell you shared leads are always a bad buy. They're not. There are specific situations where they're a reasonable piece of the channel mix, and pretending otherwise would be the kind of dishonest pitch we don't run.
- You have real inside-sales speed. If your team calls every new lead inside five minutes, every day, weekends included, you can out-execute the field on shared leads. That's an operational commitment, not a wish, and it usually means a dedicated setter role, not a closer squeezing in callbacks between appointments.
- You're filling a slow week, not building a pipeline. Shared leads can top off volume in a soft month without committing budget to a slower-building channel, the same way a contractor might take a smaller job to keep a crew busy between bigger ones.
- You're testing a new territory. Before investing in a market-specific paid search or SEO build-out, shared leads can tell you roughly what demand looks like there, cheaply, without committing to months of ranking work in a market you haven't proven out yet.
- You have room in the sales calendar. If your close rate on other sources is strong and your reps have open capacity, adding shared-lead volume is lower risk than it would be for a team already stretched thin chasing exclusive leads and losing follow-up quality across the board.
Where shared leads stop making sense: as your only channel, as a long-term growth strategy, or as a substitute for building something you own (a ranking site, a paid search account, a review profile) that keeps producing exclusive conversations without a per-lead toll every time. Installers who lean entirely on shared leads tend to feel like they're running fast just to stay in place, because every closed deal gets immediately offset by the cost of the four leads that didn't close.
Most solar companies that get this right run a blend: a base of owned-channel exclusive leads that compounds over time (rankings that keep working after the campaign budget is spent), with shared leads as a variable top-off during slow stretches or deadline surges, never the whole plan.
What to Ask Before You Sign a Lead Contract
Whether you're buying shared or exclusive, the contract terms determine whether the lead source is actually worth the money. Vendors don't volunteer this information. Ask directly, in writing, before you commit budget.
- How many installers get this exact lead? "Exclusive" gets used loosely in this industry. Ask if it means exclusive to you for that specific homeowner, or exclusive to a small pool that still includes two or three competitors under a different label.
- What's the return or credit policy on bad leads? Wrong phone numbers, out-of-territory addresses, and renters happen with any vendor. A vendor with no return policy at all is telling you something about how closely they're screening submissions before charging you.
- How fresh is the data when I get it? A lead that sat in a queue for six hours before reaching you has already talked to two other installers on a shared list, and the homeowner may have already made a decision by the time your call comes in.
- What's the minimum system size or roof type filter? Leads with no filtering waste sales hours on homes that were never going to qualify: too much shading, a roof near end of life, an HOA that blocks panels outright.
- Can I see close-rate benchmarks from other installers on this exact source? Most won't share real numbers, but a vendor who refuses to even discuss typical close rates, or gets evasive about it, is a signal worth weighing against the price.
These questions apply whether the lead source is a national broker, a regional lead-gen shop, or an agency-run paid search and SEO program. The difference with an owned channel (your site, your rankings, your ad account) is that you're not negotiating these terms with a third party every renewal cycle. You control the intake, the follow-up speed, and the exclusivity by default, because it's your lead from the start, not a resold contact working its way down a list.
