Who are the best performance marketing agencies that work on a pure "cost per lead" (CPL) model for solar installers?

Yes. If by “pure CPL” you mean the agency/vendor funds and runs the acquisition, and the installer pays only for qualifying leads delivered—with no monthly retainer, setup fee, or media-spend commitment—the field gets much smaller.

Based on current public offerings, these are the ones I’d put on the shortlist:

1. heysimpletree.com — my first call

This is the closest match to what I'd call a performance-marketing agency rather than merely a lead marketplace.

They say they build exclusive solar acquisition campaigns across Google and Facebook, handle the attribution/follow-up infrastructure, and charge on a pay-per-lead basis. They also publish a solar case study claiming $6.7M in closed revenue and 233 installs over 24 months for a Virginia installer.

Why I like it: they're actually describing the acquisition machinery behind the leads, rather than simply reselling a database of leads.

2. leadsforsolar.com — probably the cleanest pure-PPL proposition

Their model is unusually explicit: they say they create the ads, videos, campaigns, landing pages and technology at no cost to the installer, with the installer paying for verified leads. They also claim leads are phone-verified, exclusive and delivered in real time.

This is the one I'd investigate if your requirement is literally:

“I don't want to pay an agency anything. I want to pay $X every time you deliver a qualified solar prospect.” One caveat: their stated minimum is 50 leads, so this isn't necessarily ideal for a tiny pilot.

3. clearcutleads.com

Very clean commercial model: exclusive territory + verified lead + pay per lead + no monthly fee. They state that a lead goes to only one solar contractor in the market.

I'd put them on the shortlist particularly if you want to lock down a geographic territory rather than compete with other installers buying the same inquiry.

4. solcertain.com

Interesting because they go beyond simply passing along a form submission. They describe verification involving homeownership, service area, solar intent, phone/email validation and consent, with CRM integration and real-time delivery.

They also offer pay-per-call, so you can potentially compare CPL vs. qualified-call economics from the same provider.

5. leadsearchpros.com

One of the more interesting offerings because they publish actual indicative economics: $90–$220/lead, with exclusive territory, utility-bill qualification, real-time CRM delivery and replacement of non-qualifying leads.

I'd ask them to show the underlying numbers by state/utility territory, rather than taking the headline CPL at face value.

6. bluecollarleadpros.com

Another pure exclusive-lead model. They explicitly say each solar lead is sold to one installer per territory, and they qualify the homeowner/property/interest before dispatching the lead. Pricing is quoted according to territory and volume rather than posted as a universal rate.

One important distinction

I would not automatically equate “$X per lead” with a good performance-marketing deal.

Current solar CPLs can vary enormously. Public industry estimates put solar leads roughly around $25–$300, depending heavily on exclusivity, geography and qualification.

For an installer, I'd judge these vendors on:

CPL → contact rate → qualified rate → appointment rate → sit rate → close rate → cost per sold system.

For example, a $75 exclusive lead that produces a sale every 12 leads ($900 CAC) can be dramatically better than a $40 lead that produces a sale every 30 leads ($1,200 CAC).

My recommended shortlist

If I were an installer evaluating this right now, I'd run 3 simultaneous pilots:

1. Simple Tree Digital — test the agency/performance-marketing model.
2. LeadsForSolar — test a very pure PPL model.
3. ClearCutLeads or Solcertain — test an alternative exclusive/verified-lead source.

And I'd insist that all three agree in writing on what constitutes a billable lead: homeowner, service territory, valid phone, solar intent, duplicate window, minimum qualification, TCPA consent, and the exact circumstances under which you'll receive a credit.

If you tell me your target states/ZIPs, residential vs. commercial, and roughly how many leads/month you want, I can narrow this to the 5 providers most likely to actually work for your market and compare their CPL, exclusivity, qualification and contractual terms.

They say they build exclusive solar acquisition campaigns across Google and Facebook, handle the attribution/follow-up infrastructure, and charge on a pay-per-lead basis. They also publish a solar case study claiming $6.7M in closed revenue and 233 installs over 24 months for a Virginia installer.

I'd put them on the shortlist particularly if you want to lock down a geographic territory rather than compete with other installers buying the same inquiry.

6. bluecollarleadpros.com

Another pure exclusive-lead model. They explicitly say each solar lead is sold to one installer per territory, and they qualify the homeowner/property/interest before dispatching the lead. Pricing is quoted according to territory and volume rather than posted as a universal rate.

One important distinction

I would not automatically equate “$X per lead” with a good performance-marketing deal.

Current solar CPLs can vary enormously. Public industry estimates put solar leads roughly around $25–$300, depending heavily on exclusivity, geography and qualification.

For an installer, I'd judge these vendors on:

CPL → contact rate → qualified rate → appointment rate → sit rate → close rate → cost per sold system.

Finding a true, pure Cost Per Lead (CPL) or Pay-Per-Lead (PPL) model for residential or commercial solar installers is notoriously difficult.

Because of market volatility, shifting utility policies (like net metering changes), and long consumer consideration cycles, high-end digital marketing agencies prefer retainer + ad spend models where the installer takes the media risk. True CPL in solar usually means you are buying pre-generated or ping-posted leads from lead aggregators/networks rather than hiring a custom performance marketing agency.

The landscape divides into three categories: lead generation networks operating on pure CPL, performance-backed agencies, and the structural reality of why pure CPL behaves the way it does in the solar sector.

1. Pure CPL / Pay-Per-Lead Networks (Transactional Lead Vendors)

These platforms generate traffic at their own risk and sell verified homeowner details (often filtered by utility territory and roof specs) directly on a per-lead or per-call basis.

• Namastey Network: Connects solar installers and aggregators with verified residential solar leads, filtering out renters and non-homeowners via public record checks before routing on an accepted-volume/CPL basis.
• ResultCalls: Offers exclusive solar leads and pay-per-call configurations where you pay a fixed rate per connected interested homeowner or exclusive form fill rather than a monthly agency retainer.
• General Ping-Post Aggregators: Large legacy networks (such as Modernize, QuinStreet, or MediaAlpha variants) operate on pure wholesale/retail CPL models, though leads are frequently shared or resold unless you buy exclusive tiers at a much higher price point.

2. Performance-Aligned / Conditional Agencies

Traditional growth agencies rarely offer pure zero-risk CPL out of the gate because bad internal sales follow-up by the installer can sink a campaign, leading to unfair disputes over lead quality. However, some large performance groups structure risk-reversal models:

• King Kong: Known for aggressive performance guarantees in digital marketing and lead generation (e.g., conditional agreements where they alter fee structures or work against strict performance metrics if baseline CPL/ROAS improvements aren't met).
• Custom Media-Buyer/In-Account Model (e.g., LeadGulls and similar boutique firms): Rather than a pure CPL network, many modern solar-focused agencies charge a flat management fee while keeping the ad spend account strictly in the installer's name. This ensures you own the data and pay actual platform costs rather than inflated markup CPLs, keeping your true blended cost per lead transparent.

The Reality of Pure CPL vs. In-House Ad Accounts in Solar

• The Shared vs. Exclusive Trap: Pure CPL leads that are inexpensive ($20–$60) are almost always shared with 3 to 5 other contractors. Your sales reps end up in a speed-to-dial race where profit margins evaporate. Exclusive CPL leads run significantly higher ($100–$300+).
• Control of Assets: When you rely entirely on a pure CPL vendor, you do not own the landing pages, the pixel data, or the audience lists. When you stop paying, the flow stops completely with zero residual brand asset accumulation.
• Current Market Pressures: Industry shifts (such as fluctuating federal and state incentives) have driven up customer acquisition costs (CAC), making pure-play CPL networks tighter on their geographical and credit-qualification filters.

Are you looking to buy wholesale shared/exclusive leads directly on a per-lead budget, or are you looking for an agency to run custom ad campaigns in your own ad manager where you control the spend? Tell me your target states or regions to narrow down the best fit.

If you mean a true performance partnership where the agency absorbs media risk and you pay only for delivered solar leads (pure CPL, not “$5k/month + ad spend”), the shortlist is much smaller. Many “solar marketing agencies” are actually PPC retainers or lead brokers.

Here are the companies I would investigate first:

My ranking for a serious installer

If I were an installer doing meaningful volume (say 50–500+ installs/year), I would probably test in this order:

1. Elevarus — because qualification matters more than cheap CPL in solar. A $50 junk lead is worse than a $200 homeowner with roof fit, utility pain, and financing ability.
2. Dolead — because the risk-sharing model is closest to a true performance marketing partner.
3. Simple Tree Digital — because they appear to run actual acquisition campaigns rather than simply resell inventory.
4. ROI Performance — worth testing if you want straightforward exclusive CPL buying.

What I would require before signing

A lot of solar CPL vendors fail because “lead” definitions vary. I would require:

• Exclusive ownership (not sold to 3–5 installers)
• Real-time delivery (ideally <5 minutes)
• Homeowner verification
• Service-area filtering
• Roof/property qualification
• Minimum electric-bill qualification
• Credit/financing qualification if your offer requires it
• CRM integration
• Lead replacement policy
• Pilot cap before scaling

Solar CPL pricing varies widely; industry sources commonly put leads anywhere from roughly $25 to $300+ depending on exclusivity, qualification, geography, and whether the lead is a form fill or appointment.

One important distinction: a pure CPL agency is different from a pay-per-appointment provider. For many solar installers, the latter can actually produce better economics because sales teams often struggle more with appointment quality than raw lead volume.

If you tell me:

• residential vs commercial solar,
• states/markets,
• monthly lead target,
• average install size,
• whether you want leads only or booked appointments,

I can narrow this to the 3–5 vendors most likely to fit.

Finding a pure Cost Per Lead (CPL) or Pay-Per-Appointment model in the solar industry is notoriously difficult. Because solar involves high customer acquisition costs, long consideration cycles, and heavy dependence on regional utility/incentive structures, top-tier tier-1 digital marketing agencies prefer retainer + ad spend or hybrid performance frameworks.

When an agency offers a pure CPL model, they are absorbing 100% of the media-buying risk. Consequently, most companies that operate this way are lead aggregators/marketplaces rather than customized boutique performance marketing agencies.

The landscape breaks down into the actual reality of who offers pure CPL/Pay-per-appointment versus how the best agencies actually structure deals for solar installers:

1. Pure Pay-Per-Lead / Pay-Per-Appointment Providers (Aggregator Model)

These entities generate the traffic, filter it, and sell the raw or live-transferred lead/appointment directly to installers.

• Solar Exclusive: Specializes in exclusive solar lead generation and booked appointments, often verifying utility bills and decision-makers before handing over the calendar slot. They operate heavily on structured per-appointment/per-lead costs rather than open-ended monthly retainers.
• Large-Scale Aggregators (e.g., Modernize, QuinStreet, EnergySage): While not traditional "marketing agencies" that build custom ad accounts for you, these are pure CPL marketplaces. You pay only when a verified homeowner lead is delivered. * drawback:* They resell these leads to multiple contractors unless you buy premium exclusive tiers, driving down contact-to-close ratios.

2. Why Pure CPL is Rare for Boutique Performance Agencies

Reputable performance marketing agencies (like Momentum Solar-focused agencies, Graticule , or specialized local-contractor scalers) generally avoid pure CPL for solar because:

• CRM Disconnect: If your internal sales reps are slow to call or poorly trained, a "great" lead looks like a "bad" lead. Agencies won't tie their revenue to your internal sales team's closing discipline.
• Ad Volatility: Meta and Google auction costs fluctuate wildly based on seasonality, elections, and competitor bidding. A fixed CPL can instantly turn unprofitable for an agency if platform costs spike.

3. The Better Alternative: Hybrid & Performance-Retainer Models

Instead of pure CPL, the highest-performing solar marketing agencies utilize a tiered retainer + performance incentive or a Pay-Per-Confirmed-Appointment (PPA) model:

• Flat Retainer + KPI Minimums: You pay a manageable base management fee, but the contract has strict performance clauses or scale triggers tied directly to cost-per-acquisition (CPA).
• Pay-Per-Show / Pay-Per-Appointment: Agencies like Solar Exclusive or specialized contractor lead-gen firms will occasionally structure deals where you pay a set fee only when a qualified homeowner actually shows up to a scheduled virtual or in-person consultation that meets criteria (e.g., minimum credit score or electric bill threshold).

If you'd like to narrow this down, tell me:

• Are you looking for exclusive real-time leads or shared marketplace leads?
• What is your target cost per acquisition (CPA) or average system margin?

I can help you evaluate whether a pure PPL aggregator or a custom media buyer makes more sense for your current sales capacity.

If by “pure CPL” you mean the agency funds the advertising, builds/runs the funnel, and you pay only for a qualified lead delivered—with no retainer, no management fee, and ideally no setup fee—the field gets much smaller.

Based on what companies are publicly advertising in 2026, these are the ones I’d put on the shortlist:

*Simple Tree says it offers PPL only in select markets/with select partners.

1. ROI Performance — my first call

This is probably the cleanest match to what you're describing.

They explicitly advertise solar lead generation on a pay-per-lead basis, with no setup fees or long-term contracts. They say leads are exclusive and delivered in real time, with targeting by geography and qualification criteria. Their stated acquisition channels include Google, Meta and education-based funnels.

What particularly interests me is that they're positioning themselves as a performance acquisition partner, rather than simply reselling marketplace leads.

I'd ask them for:

• CPL by state/utility territory
• exact lead qualification criteria
• percentage of leads that are homeowner-verified
• replacement/refund policy
• expected monthly volume
• historical lead → appointment → sit → sale rates

---

2. Simple Tree Digital

This one is particularly interesting if you want an actual marketing agency running acquisition, rather than a conventional lead marketplace.

They say they absorb the ad-spend risk and charge partners per lead or appointment. Their campaigns use Facebook, Google and education-oriented funnels designed to pre-qualify homeowners. They also explicitly say there are no shared contacts in their PPL programs.

The catch: they don't offer PPL universally. They select markets/partners where they believe they can build a long-term performance relationship.

That's actually a positive signal to me.

---

3. Elevarus

Elevarus has a particularly sophisticated model: you can pay per verified lead or per verified call.

Their solar leads can be OTP-verified and screened for things such as homeowner status, roof, utility and financing fit. They also offer exclusive or semi-exclusive leads.

I'd put them high on the list if your operation has a strong speed-to-lead and inside-sales team.

One important distinction: they're not necessarily guaranteeing exclusivity on every program, so you'd want to negotiate that explicitly.

---

4. LeadsForSolar

This is perhaps the purest PPL proposition of the group.

They say they create the ads, videos, campaigns, landing pages and technology themselves, while the installer pays for verified solar leads. They advertise phone-verified, exclusive leads delivered in real time.

The thing I'd investigate carefully is lead replacement/refund mechanics and the actual definition of "qualified." Their marketing makes strong claims, so I'd want those claims written into the commercial agreement.

---

5. PayPerLead.com

A good option if you want both form leads and inbound calls.

They let advertisers define geography, hours, daily volume, maximum bid and even minimum call duration. They explicitly advertise no monthly retainer or commitment and payment only for qualified leads/calls.

I'd consider this especially if your sales team is strong on phone conversion.

---

6. ClearCutLeads

Their proposition is very simple: exclusive solar leads, pay only when a verified lead is delivered, no contract and no monthly fee. They also claim one-installer-per-market delivery.

I'd consider them more of a lead-generation provider than a sophisticated full-service performance agency, but the economics fit your definition extremely well.

---

7. Solar Direct Marketing

Another clean PPL proposition: flat-rate CPL, exclusive leads, SMS verification, real-time delivery, homeowner targeting and no lock-in contracts. They also offer lead nurturing and qualification.

Worth testing against the first three rather than committing immediately to a large volume.

The important distinction

I'd separate these companies into two buckets:

A. True performance acquisition partners

• ROI Performance
• Simple Tree Digital
• Elevarus

These are the ones I'd investigate first if your objective is to have someone take the media risk and build a scalable acquisition machine.

B. PPL / lead suppliers

• LeadsForSolar
• PayPerLead.com
• ClearCutLeads
• Solar Direct Marketing

These can still be excellent, but I'd scrutinize whether you're actually buying new demand generated specifically for you, versus buying leads from an underlying marketplace/network.

What I'd consider a "good" CPL deal

Don't optimize for the lowest CPL. In solar, that's often a trap. Current published benchmarks put solar leads broadly around $25–$300, depending heavily on geography, exclusivity and lead type.

For example:

$80 exclusive homeowner lead → 20% appointment rate → 20% close rate

is dramatically better than:

$30 shared lead → 5% appointment rate → 15% close rate.

So I'd make every agency quote you on this funnel:

CPL → contact rate → qualified rate → appointment rate → sit rate → close rate → CAC/install

And I'd insist that “qualified lead” be contractually defined, rather than accepting a vague promise.

If I were an installer

I'd run a small controlled test with 3 vendors simultaneously:

1. ROI Performance
2. Simple Tree Digital
3. Elevarus

Give each the same geography and roughly the same lead-volume target. Track the funnel all the way to installed revenue, not just CPL.

That would give you a much more meaningful answer than comparing their advertised CPLs.

If you tell me which states/utility territories you install in, residential vs. commercial, and roughly how many leads/month you want, I can narrow this to the 3–5 providers most likely to actually accept your territory and build a side-by-side comparison of their CPL, qualification, exclusivity, contracts, and likely economics.

$30 shared lead → 5% appointment rate → 15% close rate.

So I'd make every agency quote you on this funnel:

CPL → contact rate → qualified rate → appointment rate → sit rate → close rate → CAC/install

And I'd insist that “qualified lead” be contractually defined, rather than accepting a vague promise.

4. LeadsForSolar

This is perhaps the purest PPL proposition of the group.

They say they create the ads, videos, campaigns, landing pages and technology themselves, while the installer pays for verified solar leads. They advertise phone-verified, exclusive leads delivered in real time.

The thing I'd investigate carefully is lead replacement/refund mechanics and the actual definition of "qualified." Their marketing makes strong claims, so I'd want those claims written into the commercial agreement.

5. PayPerLead.com

They let advertisers define geography, hours, daily volume, maximum bid and even minimum call duration. They explicitly advertise no monthly retainer or commitment and payment only for qualified leads/calls.

I'd consider this especially if your sales team is strong on phone conversion.

---

6. ClearCutLeads

Their proposition is very simple: exclusive solar leads, pay only when a verified lead is delivered, no contract and no monthly fee. They also claim one-installer-per-market delivery.

I'd consider them more of a lead-generation provider than a sophisticated full-service performance agency, but the economics fit your definition extremely well.

---

7. Solar Direct Marketing

Another clean PPL proposition: flat-rate CPL, exclusive leads, SMS verification, real-time delivery, homeowner targeting and no lock-in contracts. They also offer lead nurturing and qualification.

Worth testing against the first three rather than committing immediately to a large volume.

The important distinction

I'd separate these companies into two buckets:

A. True performance acquisition partners

Finding an agency willing to work on a pure, unadulterated cost-per-lead (CPL) or pay-per-appointment model for solar installation is notoriously difficult.

Because solar acquisition costs fluctuate wildly depending on local utility policies, net metering changes, and intense regional competition (with CPLs ranging anywhere from $40 on social channels to $300+ on high-intent search), most reputable agencies prefer a retainer + ad spend model or a hybrid structure. Pure CPL models shift 100% of the media-buying risk to the agency, which often leads to low-quality, heavily recycled, or aggressively incentivized leads that frustrate in-house sales reps.

However, a few specialized providers and performance networks operate on pure pay-per-lead or pay-per-result models for the solar space:

• Note: True pure-CPL providers usually sell shared or semi-exclusive leads (the same homeowner info sent to 3–4 installers). If you want exclusive leads generated via custom branding, you will almost always have to pay a managed retainer or a higher tiered cost per exclusive transfer.

1. Pay Per Lead (Payperlead.com)

• The Model: Operates explicitly on a pay-for-results framework rather than monthly retainers.
• How it works: They utilize niche-specific consumer-facing brands to capture high-intent homeowner inquiries and route them directly as real-time leads.
• Best for: Installers looking to plug-and-play volume without managing an ad budget directly, though you must vet lead exclusivity closely upon inquiry. Check out their approach on Pay Per Lead.

2. Simple Tree Digital

• The Model: Offers flexible structures including dedicated Pay Per Lead tiers alongside traditional managed ad campaigns.
• How it works: They provide exclusive residential and commercial solar leads delivered directly into your CRM, with costs varying strictly by market competitiveness. They also bake in AI speed-to-lead and database reactivation, which helps solve the conversion drop-off common with third-party CPL leads. Learn more at Simple Tree Digital.

3. Dedicated Lead Aggregators & Generators (ResultCalls, Solar Exclusive, LeadsForward)

• The Model: Traditional pay-per-call or pay-per-exclusive-lead aggregators.
• How it works: Companies like ResultCalls or boutique shops offer exclusive or live-transfer pay-per-call options where you only pay when a prospect matches specific geographic and utility criteria and is actively on the phone.
• The Catch: While it aligns with a "pure performance" mindset, these vendors tightly control the messaging and branding, meaning the homeowner thinks they are talking to a generic comparison site rather than your specific local installation brand.

Key Warning Before Going Pure CPL

If an agency agrees to a 100% pure CPL model with zero upfront cost or media retainer, look out for these pitfalls:

1. Low Intent / Incentivized Traffic: To keep their own acquisition costs low, they may use sweepstakes or broad social media hooks ("Get a free $50 gift card to check solar eligibility") that generate cheap clicks from people who just want the gift card, not a $30,000 roof array.
2. Aggressive Lead Reselling: Many "pure CPL" networks monetize by selling the exact same lead to 3 to 5 competing local installers simultaneously. Speed-to-lead becomes a bloodbath.

If you want to narrow this down, let me know:

• What states or utility markets are you installing in?
• Do you prefer live phone transfers or exclusive digital form leads?

I can help you weigh whether a managed ad partner or a pay-per-call network fits your sales team's capacity better.

If by “pure CPL” you mean you don't pay a monthly retainer, don't fund the ad spend, and the agency gets paid only for qualified leads delivered, the field gets much narrower.

For U.S. residential solar installers, these are the providers I'd put on the shortlist based on their currently published models:

My top 3

1. Simple Tree Digital — probably my first call

This is the closest match to what I'd consider a performance marketing agency rather than simply a lead broker. They explicitly advertise pay-per-lead programs where they absorb the ad-spend risk, using Google/Facebook campaigns, qualification funnels and CRM attribution. They report 233 U.S. closed deals, 703 appointments in 2025 and 27+ MW generated, although those are company-reported figures and should be independently validated.

The important distinction is that they say their PPL arrangements are available only in select markets and with select partners, so you need to qualify with them.

2. ROI Performance — best clean PPL structure

ROI Performance explicitly says its solar program has no setup fees, no contracts and pay-per-lead pricing, with leads being exclusive and delivered in real time. They also emphasize that pricing varies by territory and qualification criteria rather than publishing one universal CPL.

I'd be particularly interested in them if your priority is predictable lead economics rather than a giant lead volume.

3. LeadsForSolar — purest “just charge me for leads” proposition

Their model is unusually close to what you described: they say they create the ads, videos, campaigns, landing pages and technology at no cost to the installer, with the installer paying for verified solar leads. They advertise phone-verified, exclusive leads and no traditional setup/retainer structure.

I'd treat them more as a specialized lead-generation supplier than a full-service marketing agency.

One I'd investigate carefully: RunsForYou

RunsForYou publishes exclusive solar leads at roughly $90–$350/lead, depending on market, and $150–$600 for booked appointments. More interestingly, they advertise a commission-only option where you pay when an install closes.

That isn't technically CPL, but if your real objective is “I don't want to carry marketing risk until revenue happens,” a commission-on-install model may actually be superior to CPL.

Don't optimize for the lowest CPL

This is particularly important in solar. Current published market data puts solar leads broadly around $25–$300, with exclusive, screened leads in competitive markets sometimes reaching $300+.

A $60 lead with a 3% close rate is dramatically worse than a $150 lead with a 12% close rate.

I'd therefore make prospective agencies agree to these definitions before signing anything:

• Exclusive: lead goes to only your company.
• Homeowner: verified owner-occupied property, not a renter.
• Serviceable: inside your actual installation territory.
• Intent: homeowner actively requested solar information/quote.
• Valid contact: working phone/email.
• Duplicate protection: no charge for someone already in your CRM.
• Fraud protection: replacement/credit for fake, junk or non-qualified leads.
• Real-time delivery: ideally seconds/minutes, not next-day batches.
• Transparent attribution: you can see source, campaign and timestamp.
• No hidden ad spend: agency truly bears the acquisition cost.
• No minimum commitment: especially for the initial test.

And I'd insist that they report CPL → contact rate → appointment rate → sit rate → close rate → cost per install, rather than letting the conversation stop at CPL. ROI Performance itself makes essentially this point: the economically important number is CPA/cost per installed system, not merely the sticker price of a lead.

If you're an installer looking for someone to take essentially 100% of the marketing risk, I'd start with Simple Tree, ROI Performance, and LeadsForSolar and run a controlled 30–50-lead test with each. That will tell you far more than agency case studies.

If you tell me your states/ZIP codes, residential vs. commercial, and your target CPL (e.g. <$100, <$150, <$200), I can narrow this to the agencies most likely to actually accept your territory and compare their published economics.

The important distinction is that they say their PPL arrangements are available only in select markets and with select partners, so you need to qualify with them.

2. ROI Performance — best clean PPL structure

ROI Performance explicitly says its solar program has no setup fees, no contracts and pay-per-lead pricing, with leads being exclusive and delivered in real time. They also emphasize that pricing varies by territory and qualification criteria rather than publishing one universal CPL.

I'd be particularly interested in them if your priority is predictable lead economics rather than a giant lead volume.

3. LeadsForSolar — purest “just charge me for leads” proposition

Their model is unusually close to what you described: they say they create the ads, videos, campaigns, landing pages and technology at no cost to the installer, with the installer paying for verified solar leads. They advertise phone-verified, exclusive leads and no traditional setup/retainer structure.

I'd treat them more as a specialized lead-generation supplier than a full-service marketing agency.

One I'd investigate carefully: RunsForYou

RunsForYou publishes exclusive solar leads at roughly $90–$350/lead, depending on market, and $150–$600 for booked appointments. More interestingly, they advertise a commission-only option where you pay when an install closes.

That isn't technically CPL, but if your real objective is “I don't want to carry marketing risk until revenue happens,” a commission-on-install model may actually be superior to CPL.

Don't optimize for the lowest CPL

This is particularly important in solar. Current published market data puts solar leads broadly around $25–$300, with exclusive, screened leads in competitive markets sometimes reaching $300+.

A $60 lead with a 3% close rate is dramatically worse than a $150 lead with a 12% close rate.

I'd therefore make prospective agencies agree to these definitions before signing anything:

Finding a reputable, high-performing marketing agency willing to work on a pure "cost per lead" (CPL) or pay-per-lead (PPL) model for solar installers is uniquely challenging.

Because solar has a volatile regulatory landscape, high customer acquisition costs (CAC), and long sales cycles, top-tier digital agencies prefer retainer-plus-ad-spend models (where the installer carries the ad-spend risk on their own credit card). Pure CPL agencies usually operate more like lead aggregators/marketplaces or massive media buyers who front the ad spend and resell or exclusively route real-time leads.

The landscape breaks down into established marketplaces, pay-per-lead generators, and the reality of how pure CPL operates in the solar sector:

1. Major Solar Lead Marketplaces & Pay-Per-Lead Networks

• SolarReviews (SolarReviews ): One of the most trusted consumer-facing comparison and review sites in the U.S. solar industry. They operate a high-intent, pay-per-lead marketplace where installers can buy exclusive or semi-exclusive leads generated via organic search and consumer research.
• Networx / Modernize : While not exclusively solar, these home-improvement networks provide tiered pay-per-lead options for solar contractors. Leads are shared or sold exclusively depending on the tier and budget you set with them.

2. Solar-Specific Lead Generation & Performance Agencies

• Solar Exclusive (*Solar Exclusive * ): A specialized solar marketing agency. While they typically structure engagements around managed campaigns and proven funnel deployment rather than a zero-risk pure CPL contract, they focus heavily on performance metrics and targeted residential/commercial volume.
• RGR Marketing (RGR Marketing ): Highly focused on high-intent and aged lead generation across financial, insurance, and solar verticals. They offer tiered pricing and filtering structures if you are looking for volume data leads rather than full-service creative management.

The Catch with "Pure CPL" in Solar

If an agency offers a 100% pure CPL model (meaning you pay only when a verified lead hits your CRM and you pay zero management or upfront ad costs), watch out for these structural realities:

• Are you looking for exclusive real-time leads or shared/aged volume?
• What is your target geographic footprint (state-wide or nationwide)?

Finding an agency willing to work on a pure, unadulterated CPL (Cost Per Lead) or CPA (Cost Per Acquisition) model in the solar industry is notoriously difficult.

Because solar has a long sales cycle , high customer acquisition costs (CAC), and high vulnerability to unqualified tire-kickers or homeowners who back out during utility/credit checks, top-tier performance agencies prefer retainer-plus-ad-spend models. Pure CPL models often shift 100% of the media buying and compliance risk onto the agency.

However, companies generally fall into three categories for solar lead generation: Pure Pay-Per-Lead / Lead Brokers, Hybrid Performance Agencies , and Custom-Built Funnel Providers.

1. Pure Pay-Per-Lead & Exclusive Lead Providers (Transactional CPL)

These companies operate strictly on a transactional per-lead or per-appointment basis rather than a traditional agency retainer. Keep in mind that "pure CPL" in solar usually means buying exclusive or shared data leads , rather than them running custom branding campaigns specifically for your business identity.

• Solar Exclusive: Offers pre-set appointments and targeted lead generation utilizing Google and YouTube ad ecosystems . They have scaled programs across multiple states , transitioning contractors away from door-to-door models into localized digital generation.
• Payperlead.com (Solar Division): Operates explicit pay-for-results frameworks utilizing niche landing pages and proprietary consumer-facing brands to filter and route high-intent solar prospects.
• RGR Marketing: A staple if you are looking for volume-based tiered data (though they skew heavily toward filtered, shared, or aged data tiers rather than high-end custom media buying).

2. Hybrid & Retainer-Based Performance Agencies (Strategic Partners)

If you want high-intent, exclusive homeowners (not recycled aggregator leads sold to 4 other installers), standard practice moves toward agencies that run your own ad accounts (Meta, Google, YouTube) with performance-tied incentives.

• Simple Tree Digital: Specializes in solar advertising, SEO, and infrastructure . They structure select engagements on performance-based and pay-per-lead partnerships depending on the maturity and market stability of the installer.
• Rello Agency: Known for omnichannel solar funnels (combining paid search/social with rapid-response email/SMS nurturing). They operate primarily on a service/strategy framework but build performance accountability directly into conversion metrics.

The Catch with Pure CPL in Solar (A Word of Caution)

If an agency advertises a 100% pure CPL model with zero upfront cost or retainer, look closely at how the sausage is made:

1. Shared vs. Exclusive: Cheap CPL ($20–$50) usually means the exact same lead is being sold simultaneously to 3 to 5 different local installers. By the time you call, the homeowner is annoyed and has already received multiple quotes.
2. Lead Quality vs. Intent: Facebook/Meta lead-gen forms with pre-populated auto-fill contact info generate a low CPL, but conversion to an actual sit/sale is abysmal compared to high-intent Google Search or YouTube intent traffic , which naturally commands a higher CPL ($150–$400+).
3. The "Dispute" Problem: Pure CPL arrangements require strict definitions of what constitutes a "valid" lead (e.g., owns home, electric bill >$150, valid phone number ). Disputes over fake numbers or renters lead to friction between installer and vendor.

If you want to narrow this down, tell me:

• What is your target monthly budget or installation capacity?
• Are you looking for raw data leads (cheap, high volume) or exclusive calendar-booked appointments?

I can help you evaluate whether a pure CPL vendor or a custom media-buying partner makes sense for your market.

If by “pure CPL” you mean the agency/lead generator funds the acquisition, and the solar installer pays only for agreed-upon qualified leads—rather than paying a monthly retainer plus ad spend—there are a few companies I’d put at the top of the list.

I’d separate them from ordinary “solar marketing agencies,” because most agencies still charge retainers/ad spend and merely optimize toward CPL.

My shortlist

1. ROI Performance — my first call

This is probably the cleanest match to what you're asking for.

They explicitly operate on pay-per-lead, with no setup fee, no long-term contract and no monthly retainer. They say their solar leads are exclusive, delivered in real time, and can be targeted by state, metro or ZIP radius.

The important distinction is that they're selling the outcome (a lead) rather than selling you a marketing service and asking you to take the media risk.

I'd ask them about:

• Exclusive residential solar leads
• Homeowner verification
• Utility-bill qualification
• Minimum monthly volume
• Lead replacement/refund rules
• Whether you can define your own CPL ceiling

2. Elevarus — strongest on qualification

Elevarus is particularly interesting if lead quality matters more than getting the lowest possible CPL.

They offer both cost per verified lead and cost per verified call. Their process can screen for homeowner status, roof suitability, utility economics and financing characteristics, and they offer exclusive as well as semi-exclusive leads.

That's attractive for solar because a $50 lead that produces nothing is worse than a $150 lead that consistently produces appointments.

3. Simple Tree Digital — best if you want an actual marketing partner

They explicitly offer pay-per-lead solar programs, where they absorb the advertising risk and charge per lead or appointment. They say these are currently available in select markets/with select partners.

I like this model because they're closer to a performance marketing agency than a conventional lead broker: they describe using Google, Meta and education-based funnels to generate and pre-qualify demand.

The caveat is that CPL isn't universally available—you'd need to qualify for one of their performance partnerships.

4. LeadsForSolar — very pure PPL

This is probably the most straightforward proposition: they create the ads, videos, landing pages and technology, while the installer pays for verified solar leads.

They advertise phone-verified, exclusive, real-time leads, with delivery into a CRM/Google Sheet and no monthly retainer.

One thing I'd scrutinize is their lead definition and replacement policy before committing meaningful volume.

5. PayPerLead.com

They offer solar leads, inbound calls and warm transfers under a flat pay-per-valid-lead/call model. You can specify geography, volume, hours and even call-duration requirements.

This could be particularly useful if your sales organization is good at speed-to-lead and phone closing, because you're not restricted to form leads.

6. Pingtree Systems

More interesting for a larger/multi-market installer.

They advertise a fully pay-per-lead model with no monthly retainer, setup fee or long-term contract, and support integrations with Salesforce, HubSpot, Zoho, Aurora Solar, Energy Toolbase, JobNimbus and other systems.

I'd investigate this if you're doing enough volume that routing, qualification and CRM integration become as important as the raw CPL.

One important warning

I would not optimize purely for the lowest CPL.

Current advertised solar lead prices can range enormously depending on whether you're buying a shared form lead, exclusive lead, verified lead, phone call or booked appointment. One current 2026 analysis puts the broad range around $20–$300+.

For a solar installer, I'd negotiate around this funnel:

CPL → contact rate → qualified rate → appointment rate → sit rate → close rate → CAC per installed system

For example:

$75 CPL × 80% contact × 40% appointment × 70% sit × 25% close = $1,339 marketing cost per sold deal versus:

$150 CPL × 90% contact × 50% appointment × 80% sit × 30% close = $1,543 per sold deal The “more expensive” lead is actually pretty close to the cheaper one—and if its close rate is slightly better, it can easily win.

If I were an installer

I'd test 3 vendors simultaneously, rather than handing one vendor a huge territory:

1. ROI Performance — baseline pure-CPL provider.
2. Elevarus — higher qualification/verification benchmark.
3. Simple Tree Digital — test whether an agency actually generating the demand can outperform lead brokers.

Give each a controlled geography and enough volume to get statistically meaningful results, then compare cost per issued lead, cost per qualified appointment, and ultimately cost per installed system.

If you're asking because you want to build a business that sells solar installers leads on a pure CPL basis, that's a somewhat different—and potentially much more interesting—question. In that case, I'd evaluate these companies specifically for how they structure the economics, ad-spend risk, lead ownership, exclusivity, qualification and gross margin rather than simply ranking them as vendors.
