Commercial and Residential Solar Leads

Updated September 2026 · Written and maintained by the Progression Agency strategy team

Commercial and residential solar share a technology and almost nothing else. One is a consumer purchase decided in weeks by a household; the other is a capital project decided over quarters by several stakeholders against a finance case. A lead source good at one is usually poor at the other, and most solar lead advice mixes them together. This page separates them, sets out where each kind of lead genuinely comes from, and explains why installers comparing suppliers on cost per lead are comparing the wrong figure.

Commercial solar leads and residential solar leads are different businesses

They share a technology and almost nothing else. The buyer, the sales cycle, the finance and the cost per acquired customer differ by an order of magnitude, and a lead source good at one is usually poor at the other.

This is the first thing to establish, because a great deal of solar lead advice mixes them together and is therefore wrong for whichever one you actually sell.

Residential solar is a consumer purchase: one decision-maker, a household budget, an emotional and financial mix of motivations, and a cycle measured in weeks. Commercial solar is a capital project: several stakeholders, a finance case that has to survive scrutiny, a procurement process, and a cycle measured in quarters or years.

Where residential solar leads actually come from

Search, paid social, door canvassing, referral and purchased leads — and the economics of each differ far more than the volume figures suggest.

Every residential installer eventually runs a mix, because no single source scales cleanly. The question is which mix, and the answer depends heavily on how good your close rate is, because purchased leads punish a weak sales process ruthlessly.

Search

The highest-intent source available. Someone typing about solar panel cost is further along than anyone you can interrupt. Slow to build, and it compounds.

Paid search

Buys the same intent immediately at a cost per click that is high but usually justified by deal size. The obvious first move while organic builds.

Paid social

Creates demand rather than capturing it, so lead quality is lower and volume is higher. Works when the offer is a genuine reason to inquire rather than a generic quote form.

Purchased and shared leads

Available in volume, sold to several installers simultaneously, and punishing if you are not first to call. Cost per signed job is the only figure worth quoting.

Door canvassing

Still effective in the right neighborhoods, particularly where installations are visible. Expensive in labor and increasingly regulated.

Referral

The best-converting source in the category by a wide margin, and the one most installers never systematize. A previous customer’s neighbor is the warmest lead available.

Installed-base marketing

Existing customers adding battery storage, EV charging or system expansion. Almost free, and routinely ignored.

Why purchased residential leads disappoint so often

Because they are shared, aged, and priced per lead rather than per outcome — so the supplier’s incentive is volume and yours is conversion.

This is not an argument against buying leads. Plenty of installers build a business on them. It is an argument for measuring them correctly, which almost nobody does.

The only number that matters is cost per signed contract. A lead at a low price with a very low close rate is more expensive than an exclusive lead at several times the price. Installers comparing suppliers on cost per lead are comparing the wrong figure, and the lead sellers know it.

1. Ask whether the lead is exclusive or shared, and with how many other installers.
2. Ask how old the lead is when you receive it. Minutes matter enormously in this category.
3. Track cost per signed contract by source, not cost per lead. This single change reorders most supplier comparisons.
4. Measure speed to first contact. Being first to call is the largest controllable variable in shared-lead conversion.
5. Track close rate by source separately, because a source producing plenty of appointments and no contracts is worse than one producing fewer of both.
6. Set a replacement policy in the contract for obviously invalid leads, and actually use it.
7. Review quarterly and cut the worst source rather than adding a new one on top.

How commercial solar leads are actually generated

Referral, outbound to named accounts, industry and trade networks, and search for the specific terms a facilities or finance person would use. Not lead forms.

The mental model that works for residential fails completely here. Nobody with authority over a capital project fills in a quote form. Commercial solar lead generation is closer to B2B enterprise sales than to home improvement marketing.

Named-account outbound

Identify the buildings and businesses that suit solar — roof area, ownership, energy load, tenure — then approach them specifically. Slow, and the highest-quality pipeline available.

Referral from existing commercial clients

Facilities managers and finance directors talk to their counterparts. One completed project in a sector opens the sector.

Trade and industry bodies

Where the buyers actually gather. Presence here is a long game and produces credibility no advertising buys.

Search, for finance-led terms

Commercial buyers search differently: payback period, depreciation treatment, power purchase agreements, roof suitability. Content answering those reaches them at the right stage.

Energy consultants and brokers

Frequently the actual gatekeeper to a commercial project, and an under-worked relationship for most installers.

Property and portfolio owners

One relationship can produce many sites, which changes the economics of business development entirely.

Public sector and framework agreements

Long, procedural, and durable once you are on a framework.

What a commercial solar lead should actually contain

A named stakeholder, the building, the energy load, ownership status and the trigger. Anything less is a contact, not a lead.

This is worth defining internally, because sales and marketing in this sector routinely argue about lead quality without ever having agreed what a lead is.

Solar installer leads: what the installer can control

Speed of response, the quality of the site survey, and how the proposal presents the finance case. Those three do more for close rate than any change of lead source.

Installers frequently look for a better lead source when the constraint is actually the process that follows the lead. Doubling a close rate has the same effect on revenue as doubling lead volume, costs far less, and does not degrade at scale.

• Speed to first contact, measured in minutes rather than hours, particularly for shared leads.
• A consistent qualification script, so unviable inquiries are identified before a survey is booked.
• Site survey quality, because that visit is where trust is won or lost.
• Proposals that lead with the finance case rather than the equipment specification.
• Clear, honest treatment of payback and assumptions, which survives comparison with competitors who overstate.
• A follow-up sequence for the majority who do not decide immediately, which is where most residential pipeline is lost.
• Review collection after installation, since reviews drive the search and referral channels that cost least.
• An installed-base program for storage, EV charging and expansions.

What to measure in solar lead generation

Cost per signed contract by source, close rate by source, speed to contact, and revenue per installed job. Not leads.

Lead counts are the metric the industry reports and the metric that explains least. Two sources producing identical lead volumes can differ fivefold in what they eventually cost per contract, and only the downstream measurement reveals it.

How does the incentive landscape change what a lead is worth?

Commercial solar economics are driven by tax credits, depreciation treatment and utility interconnection rules, and all three change on legislative timelines. A lead generated under one set of assumptions can be worth materially more or less by the time it is worked.

This is unlike most lead generation, where the value of an inquiry moves slowly. Here a change to credit eligibility, a step-down in rate, or a shift in how a system may be depreciated can move the payback period on a commercial installation by years — which decides whether the buyer proceeds at all. The same is true of net metering and interconnection policy, which are set at state and utility level and vary enormously between neighboring territories.

The operational consequence is that lead value has to be reassessed by jurisdiction rather than assumed nationally, and that a pipeline built during a favorable window will convert at a different rate once the window moves. Installers who price lead acquisition off a blended national average consistently overpay in restrictive territories and underinvest in permissive ones.

It also changes the content that generates qualified inquiries. A page explaining what a specific state’s interconnection queue actually involves, or what the current depreciation treatment means for a particular buyer type, reaches people at the moment they are evaluating — and it dates. Publish the date of the position and revisit it, because a confidently stated obsolete incentive is worse for trust than saying nothing.

Who actually signs off a commercial solar project, and what does each of them need?

Rarely one person. A commercial installation typically needs a facilities or operations view, a finance view, and someone with authority over the building itself — and a lead that has only reached one of the three is earlier than it looks.

Facilities cares about disruption, roof condition, warranty implications and what happens on the day. Finance cares about how the project is paid for, how it lands on the accounts, and what the payback assumptions rest on. Whoever controls the building — an owner, a landlord, sometimes a lender with a charge over the asset — cares about the structure, the lease and the term.

That last one is the most frequent silent disqualifier. A tenant with four years left on a lease cannot sign a twenty-year asset onto a roof they do not own, and no amount of nurture resolves it. Asking about ownership and lease term early is not a barrier to conversion; it is what stops you spending a quarter on something that was never permitted to proceed.

In practice this means the qualifying questions should establish tenure and decision structure before technical detail. A lead that names the roof, the tenure and who signs is worth several that record only an energy bill and an interest level.

Residential and commercial handled separately

Different buyers, cycles and finance. One program serving both serves neither.

Search built for the terms buyers actually use

Payback period and roof suitability for commercial; cost and savings for residential. See our SEO services.

Purchased leads measured properly

Cost per signed contract by source, which reorders most supplier comparisons. See how contractor lead buying works.

Speed to contact instrumented

The largest controllable variable in shared-lead conversion.

Referral and installed-base systematized

The cheapest pipeline in the category and the one most installers never build.

What makes solar leads different

The purchase is capital-scale, incentive-dependent and reversible in the customer’s mind for weeks. Incentives change by state and by year, which means content goes stale faster than in any comparable trade and a page quoting last year’s credit is worse than no page.
