Exclusive vs shared vs aged solar leads — the honest comparison.
Three lead types, what each actually costs you once contact rate and rep time are counted, and the genuine case for buying each one. We sell exclusive leads, so we have a horse in this race — which is exactly why the case for the other two is stated properly below rather than strawmanned.
What is the difference between exclusive, shared, and aged solar leads? An exclusive lead is sold to exactly one buyer; a shared lead is sold simultaneously to several companies who then race each other to the homeowner; an aged lead is older data resold at a discount, usually after other companies have already worked it. Exclusive leads cost the most per unit and typically produce the lowest cost per sale for teams with fast follow-up. Shared leads suit high-volume operations with many dialers and thin margins per contact. Aged leads only make sense as cheap filler for teams with idle capacity and a disciplined long-cycle nurture process.
The three lead types, compared on what matters.
Swipe the table sideways to see all three →
| Exclusive | Shared | Aged | |
|---|---|---|---|
| Buyers per lead | One | Typically three to five, sometimes more | Unknown — often several, over time |
| Price per lead | Highest | Middle | Lowest |
| Who you compete with | Nobody, on this lead | Every other buyer, simultaneously | Everyone who worked it before you |
| Typical contact rate | Highest — one call, expected | Lower — homeowner fields several calls fast | Lowest — stale numbers, moved homeowners |
| Conversation starts as | A design conversation | A price war you may have entered fourth | “Who is this? I did that months ago.” |
| Speed-to-lead sensitivity | Moderate — you still should call fast | Extreme — minutes decide it | Low — the race is already lost or moot |
| Rep morale cost | Low | Moderate — repeated rejection at speed | High — heavy rejection volume |
| Volume available | Limited by definition — capped by territory | High | Very high |
| Best fit | Teams with fast, professional follow-up and margin to protect | High-headcount dialing operations with tight processes | Idle capacity, disciplined long-cycle nurture, low expectations |
| Typical close-rate premium | Commonly reported at roughly 2–3× a shared lead’s close rate, across lead-generation industries | The baseline that premium is measured against | No solid cross-industry figure — but every buyer report available treats it as worse than shared, not better |
Contact and close rates vary enormously by team, territory, and follow-up discipline — the directional patterns above reflect widely reported buyer experience across the industry, not measured results from any one vendor including us. The close-rate premium row specifically is a cross-industry pattern from mortgage, insurance, legal, and home-services lead generation — solar-specific, independently verified studies are scarce, so treat it as directional, not a measured claim about any vendor including us. Run your own numbers before treating any row as a forecast.
The genuine case for each one.
Every lead type exists because it works for somebody. Here is who, stated the way that type’s best vendor would state it.
Buy exclusive when…
Your close rate is good and your margin per install is worth protecting; your team calls within minutes, not days; you would rather have fewer conversations that go somewhere than many that turn into price comparisons. The premium buys you the absence of competitors on the same homeowner — which is only worth paying for if you actually show up first.
Buy shared when…
You run a large dialing floor with genuinely fast, disciplined speed-to-lead, and your model is built on volume rather than per-deal margin. If you can consistently be the first of five callers and your reps are strong on differentiation, shared economics can beat exclusive economics. This is a real strategy, not a consolation prize — it just requires being better than four competitors at once, every time.
Buy aged when…
You have paid rep capacity sitting idle and a long-cycle nurture process that does not depend on urgency. Aged data is cheap enough that a very low conversion rate can still pencil, and homeowners genuinely do come back into market. It fails when it is used as a primary pipeline or when the seller quietly presents it as fresh.
Your speed to lead changes which type wins.
The comparison above is not fixed — it moves with one number about your own operation. Be honest about that number before choosing a lead type.
This is also the honest reason a good vendor asks about your follow-up process before selling to you. A buyer who cannot work leads quickly will conclude the leads were bad — and from where they sit, that conclusion is indistinguishable from the truth.
What changes about this in Illinois.
Lead type is a national question. How much a good conversation is worth is a local one — and Illinois raises the stakes on both ends.
The practical upshot: in Illinois, the gap between a well-informed lead and a curious one is wider than in a simpler market. Whatever lead type you buy, the question of what the homeowner already understood before you called matters more here than it does elsewhere.
Lead types, answered.
What does "exclusive" actually mean when a vendor says it? +
It varies, which is the problem. Some vendors mean one buyer permanently. Some mean one buyer at a time, with the lead recycled later. Some mean one buyer per product category, so a roofing company and a solar company both receive it. The word carries no fixed industry definition, so the only reliable version is the one written into the purchase agreement with a number attached and a resale prohibition alongside it.
How many companies typically receive a shared solar lead? +
Commonly three to five, though it can be more, and buyers frequently report that the number is higher than what was described at purchase. Ask for the cap in writing. A vendor unwilling to commit to a maximum number of buyers per lead is telling you the number is variable and unfavourable.
Are aged solar leads ever worth buying? +
Yes, in a specific situation: you have paid rep capacity that would otherwise sit idle, and a nurture process built for long cycles. At low enough prices, even a very low conversion rate can pencil, and homeowners genuinely do re-enter the market months later. Aged leads fail when they are used as primary pipeline, when expectations are set as though they are fresh, or when a vendor sells them without disclosing their age.
Is a more expensive lead always better? +
No. Price signals what a vendor believes their lead is worth, not what it is worth to you. The measure that matters is cost per sale — price divided by your realistic close rate on that lead type — compared against your gross margin per install. A cheap lead with a workable close rate beats an expensive one your team cannot convert, and plenty of expensive leads are simply overpriced.
Can I mix lead types? +
Yes, and experienced buyers usually do. A common pattern is exclusive leads for the closers with the strongest conversion, shared volume to keep newer reps busy, and aged data as filler for slow periods. The failure mode is measuring them together — blend the reporting and you lose the ability to tell which type is actually paying for itself.
What is the single biggest predictor of whether bought leads work? +
Speed to first contact, by a wide margin, followed by follow-up persistence. Neither is something a vendor controls. This is why lead quality disputes are so common: both sides are usually partly right, and the only way to settle it is a pilot block worked properly, with dispositions recorded, so the conversation is about data rather than impressions.
