Solar Leads: How to Buy, Generate, and Convert Them
Solar leads keep every installer's pipeline full, but the math behind them shifted in 2026. With the federal solar tax credit for homeowner-owned systems gone, residential solar leads now depend more on financing path, storage interest, and utility rates than on a tax deadline.
Demand hasn't disappeared. Installers added 4,647 MWdc of residential capacity in 2025, down just 2% from 2024, while the commercial segment grew 6%, according to SEIA and Wood Mackenzie. That still leaves a lot of companies chasing the same homeowners.
This guide covers solar lead generation from both sides. You'll see when it makes sense to buy solar leads, what solar leads for sale actually cost, and how to vet solar lead generation companies. It also covers what happens after the signature, because a lead only pays off once the system is installed.

What Are Solar Leads?
A solar lead is a property owner who has shared contact information and shown interest in solar, battery storage, or both. Leads range from a raw web form submission to a confirmed in-home appointment. The closer a lead is to a verified, qualified buyer, the more it costs and the more it's worth.
Keep these four stages separate when you track results:
Lead: Contact information plus expressed interest.
Appointment: A scheduled consultation, in person or virtual.
Signed contract: A customer who has signed but isn't installed yet.
Completed project: A system that is installed, inspected, and granted permission to operate (PTO).
Lead vendors usually report on the first two stages. Your profit depends on the last one.
What Makes a Qualified Residential Solar Lead?
Qualified solar leads pass a quick technical and financial screen before anyone spends time on a site visit or proposal. Use this table on the first call or build it into your intake form.
Qualification Area | What to Check |
Property | Ownership, roof age and material, usable roof area, shading, structural red flags, HOA rules |
Electricity | 12 months of kWh usage, utility rate schedule, time-of-use rates, main service rating, busbar capacity, existing PV |
Project economics | Cash, loan, lease, or PPA preference, state and local solar incentives, realistic savings expectations |
Sales readiness | All decision-makers available, timeline, competing quotes, documented consent to contact |
Electrical Service Capacity
Electrical service capacity deserves an early look. The backfeed a system needs, compared with what the busbar allows, determines whether a project needs a main panel upgrade or another interconnection method.
For example, here's how the NEC 705.12 120% busbar rule works on a common panel:
Panel: 200A busbar with a 200A main breaker
Maximum PV backfeed breaker: 40A, when the applicable requirements are met, including placing the PV breaker at the opposite end of the busbar from the main
Maximum continuous inverter output: About 32A, since the calculation applies 125% to inverter output current
A larger system on that same panel, or a 100A panel with only 20A of headroom, needs a different calculation or interconnection method.
Use this quick screen on the first call:
☐ Ask for a photo of the panel label and main breaker
☐ Run a quick check with the NEC 705.12 busbar calculator
☐ If the numbers come up short, evaluate a main breaker derate or supply-side connection to avoid a main panel upgrade
☐ Flag the project so the proposal reflects the likely interconnection method
Storage Interest
Treat storage interest as its own qualification signal. Strong solar plus storage prospects include homeowners with:
Evening-peak TOU rates
Net billing tariffs with low export credits
Grid-outage-prone feeders
Existing PV, which makes them battery retrofit candidates
On tight panels, a power control system can limit current under NEC 705.13 and sometimes keep a project out of a panel upgrade.
Financing Path
Financing path also matters more in 2026. Homeowner-owned systems no longer receive a federal credit, so many residential deals now run through leases or PPAs where the system owner may claim the Section 48E credit.
Here's how timing works under IRS Notice 2025-42:
Construction began by July 4, 2026: The solar facility generally remains eligible beyond 2027.
Missed that deadline: The solar facility generally must be placed in service by December 31, 2027.
Battery storage: Not subject to that same solar cutoff, which adds value to storage-ready leads.
Meeting the construction deadline is one condition, not a guarantee of eligibility. Projects still need to satisfy continuous construction, prohibited foreign entity sourcing, and other Section 48E requirements, so confirm eligibility with your TPO financing partner before building tax credit assumptions into a proposal.
Early Disqualifiers
Use these early disqualifiers as screening signals only
☐ Renter or non-owner with no property owner involved
☐ Heavy shading across every usable roof plane
☐ Roof near end of life with no budget to replace it
☐ Annual usage too low to support a viable system size
☐ Electrical upgrade costs that break the homeowner's budget
None of these is final without a site visit. A solar site survey confirms roof structure, shading, and electrical conditions before design starts.
Should You Buy Solar Leads or Generate Your Own?
Most installers do both. Buying residential solar leads adds volume fast and helps you enter new territories. Self-generated leads may become more cost-effective as referral and organic channels mature, though their close rate still depends on targeting and follow-up.
Factor | Buying Leads | Generating Your Own |
Speed | Leads within days | Months for SEO and referrals to build |
Cost per lead | Higher, set by the vendor | Lower over time, with upfront time and spend |
Exclusivity | Often shared with other installers | Yours alone |
Quality control | Depends on vendor filters | You set the criteria |
Scalability | Scales with budget | Limited by marketing capacity |
The right mix depends on your sales capacity and cash flow. Here's a starting point by business model:
New company or new market: Test demand with a small batch of exclusive or appointment leads while local SEO builds.
Established local installer: Lean on referrals and search, and buy leads mainly to fill seasonal gaps.
Multi-state sales organization: Blend several vendors with in-house paid search, and track cost per completed project by source.
Types of Solar Leads for Sale
Solar leads for sale come in a handful of formats. The biggest differences are how many installers receive the same lead and how much qualification happens before it reaches you.
Lead Type | How It Works | Competition | Best Fit |
Shared | Sold to several installers at once | High; speed decides who wins | Fast-response sales teams |
Exclusive | Sold to one installer only | Not resold by that vendor; homeowner may still get other quotes | Smaller teams and higher-price markets |
Appointment | Vendor books a consultation on your calendar | Usually exclusive | Teams without appointment setters |
Live transfer | Vendor qualifies by phone, then transfers the call | Exclusive in real time | Teams with staffed phones |
Pay per sale | You pay after a closed deal | Varies by vendor | Installers with tight cash flow |
Email-only | Homeowner opts out of phone contact | Varies by vendor | Nurture-heavy sales processes |
Aged | Older leads resold at a discount | High; often contacted before | Low-cost reactivation campaigns |
Shared leads aren't automatically low quality. One large marketplace reported that its leads were sold to an average of 2.2 companies in 2022, with prices falling as more buyers share each lead.
How Much Do Solar Leads Cost?
Solar lead prices depend on exclusivity, verification, and how the lead was generated. SolarReviews, which sells solar leads, publishes solar lead price ranges of roughly $25 to $300 per lead.
Its ranges run about $150 to $300 for exclusive high-intent web leads, $80 to $150 for shared high-intent leads, and $25 to $70 for affiliate or call center leads. Treat these as one seller's figures, not industry averages.
Appointments and live transfers usually cost more per unit, since the vendor handles part of the qualification. Prices also shift by market and season.
These factors move the price up or down:
Exclusivity and the number of buyers per lead
Verification steps, such as phone PIN checks and roof screening
Geography, utility territory, and local competition
Filters you add, such as homeowner status or a minimum electric bill
Lead source, such as organic search versus incentivized forms
How to Calculate Solar Lead ROI and Acquisition Cost
Lead price alone doesn't tell you which source is cheaper or more profitable. Start with what each source costs to produce a completed project, then compare that cost with the gross profit each project earns.
Lead cost per signed contract = Total lead spend ÷ Signed contracts
Lead cost per completed project = Total lead spend ÷ Projects reaching PTO
Return on lead spend = (Gross profit from completed projects − Total lead spend) ÷ Total lead spend
Metric | Shared Leads | Exclusive Leads |
Price per lead | $100 | $225 |
Leads purchased | 200 | 200 |
Total lead spend | $20,000 | $45,000 |
Close rate | 6% | 14% |
Signed contracts | 12 | 28 |
Lead cost per signed contract | $1,667 | $1,607 |
Cancellations before PTO | 3 | 4 |
Projects reaching PTO | 9 | 24 |
Lead cost per completed project | $2,222 | $1,875 |
Gross profit per completed project (assumed) | $9,000 | $9,000 |
Total gross profit | $81,000 | $216,000 |
Gross profit after lead spend | $61,000 | $171,000 |
Return on lead spend | 3.1x | 3.8x |
Hypothetical figures for illustration only, not industry benchmarks.
In this example, exclusive leads cost more than twice as much per lead but less per completed project, and they return more per dollar of lead spend. Your own numbers could flip that result, which is why tracking by source matters.
A lead source is sustainable only when its full acquisition cost per completed project stays well below your gross profit per project. Use your actual average system size, price per watt, and margin rather than the assumed figure above.
For a fully loaded customer acquisition cost, add these to lead spend:
Sales commissions and setter wages
CRM, dialer, and proposal software fees
Design time spent on proposals that never close
Travel time for site visits
Solar Lead Generation Companies: What to Compare
Solar lead generation companies use different business models, and the model shapes the lead you receive. The examples below show common provider types. GreenLancer has no affiliation with these companies, and this isn't a ranking.
Provider Type | Example | Lead Model | Typical Pricing | What to Verify |
Quote marketplace | EnergySage | Homeowners compare quotes from vetted installers who pay a fee to participate | Participation fee | Fee terms and how many installers quote each homeowner |
Lead marketplace | SolarReviews | Sells verified leads at exclusive and shared tiers | Per lead, priced by exclusivity | Buyers per lead and return policy |
Appointment setter | Independent agencies | Books consultations on your calendar | Per appointment, sometimes only when the appointment is kept | Show rate guarantees and replacement terms |
Performance marketing agency | Independent agencies | Runs ads and delivers leads to your CRM | Management fee plus ad spend you fund | Who owns the ad accounts, data, and creative |
The pricing model shifts risk. Per-lead vendors leave contact and qualification risk with you, while appointment setters absorb some of it and charge more per unit.
Agencies give you more control and lead ownership, but you carry the ad performance risk. Whichever model you test, ask for sample leads and recent results from installers in your territory, then verify with a small pilot before signing a large commitment.
How to Vet a Solar Lead Provider
A short vetting process cuts wasted spend and protects you from compliance trouble. Work through this checklist before you sign.
Lead source: Ask whether leads come from organic search, paid ads, or incentivized forms.
Exclusivity: Get the maximum number of buyers per lead in writing.
Freshness: Confirm how quickly leads reach you after the homeowner submits.
Filters: Set homeowner status, ZIP codes, roof type, and minimum bill.
Returns: Review the credit policy for wrong numbers, renters, and duplicates.
Consent records: Request proof of consent for every lead.
Contract terms: Check minimum spend, prepayment, and cancellation terms.
Pilot: Start small and measure cost per completed project before scaling.
Solar Lead Consent and TCPA Basics
Buying a lead doesn't automatically give you permission to call or text with automated tools. Marketing calls and texts fall under the TCPA and the FTC Telemarketing Sales Rule.
The FCC's one-to-one consent rule never took effect. The Eleventh Circuit vacated it in January 2025 in Insurance Marketing Coalition v. FCC.
Prior express written consent is still required for autodialed or prerecorded marketing calls and texts.
Numbers on the National Do Not Call Registry generally can't receive sales calls without consent or an established business relationship.
Under the Do Not Call rules for sellers, that relationship lasts up to 18 months after a purchase and three months after an inquiry.
Several states add stricter rules on consent and calling hours.
Store consent certificates, such as TrustedForm records, with each lead.
This is general information, not legal advice. Have a telemarketing attorney review your outreach process.

How to Generate Solar Leads Without Buying Them
Self-generated leads take longer to build but can become more cost-effective as channels mature. Their close rate depends on source quality, targeting, and follow-up.
Channel | Upfront Cost | Time to Results | Lead Quality |
Local SEO and Google Business Profile | Low | Months | High |
Paid search | Medium to high | Days | High intent, competitive bids |
Social ads | Medium | Days to weeks | Mixed; needs strong qualification |
Customer referrals | Low | Ongoing | Very high |
Trade partnerships | Low | Months | High |
Events and home shows | Medium | Weeks | Mixed |
Door-to-door canvassing | Labor-heavy | Immediate | Mixed; check local solicitation permits |
For local search, Google says local results are based mainly on relevance, distance, and prominence, and review count and rating play a role. A complete profile with project photos and steady reviews is one of the cheapest lead sources you can build.
Solar company marketing strategies go deeper on content and paid channels. A solar referral program turns past customers into a steady source, and avoiding common solar marketing mistakes keeps budget from leaking.
Free Solar Leads That Actually Work
Some of the best residential solar leads cost nothing but follow-up time. Start with the customers and partners you already have.
☐ Use PTO as a natural moment to request a review and referral.
☐ Partner with roofers who see aging roofs before homeowners request solar quotes.
☐ Reactivate stalled quotes, especially homeowners who paused over price or financing.
☐ Offer battery retrofits to past solar customers on TOU or net billing tariffs.
☐ Cross-sell solar to EV charger customers, since a new charger already requires a load review.
That last point works in both directions. EV charger installations require an electrical load evaluation under the locally adopted NEC, including Article 220 in the 2023 edition or Article 120 in the 2026 edition, which puts service capacity on the table. If you offer chargers, EV charger permit design fits naturally alongside solar and storage work.
How to Generate Commercial Solar Leads
Commercial solar leads come from a different set of sources, and the segment grew in 2025 while residential stayed roughly flat. Sales cycles run longer because owners weigh tax strategy, site suitability, and internal approvals.
Look for commercial solar leads here:
Property managers and owners of large flat-roof buildings
Facilities with high demand charges, such as cold storage and manufacturing
Utility efficiency programs and energy audit providers
Commercial roofers and electrical contractors
Energy brokers and consultants
Qualify commercial prospects with this checklist:
☐ 12 months of interval data, demand charges, and rate schedule
☐ Roof age, warranty, and structural capacity, or available land
☐ Ownership structure and who signs the contract
☐ Tax appetite, or interest in a PPA instead
☐ Known interconnection constraints at the site or on the feeder
How to Convert More Solar Leads Into Completed Projects
Converting solar leads happens in three stages, and each stage has its own failure points. Track drop-off at every stage so you know exactly where money leaks out.
Lead to Appointment
Rapid follow-up is one of the biggest factors in qualifying a lead. In older cross-industry research from 2011, firms that contacted online leads within an hour were nearly seven times as likely to qualify them as firms that waited longer, according to Harvard Business Review.
Route new leads to a rep's phone instantly, not to a shared inbox.
Call within minutes, then follow up by text and email where consent allows.
Plan multiple attempts over several days before closing out a lead.
Run the qualification checklist on the first call.
Appointment to Signed Contract
Accurate proposals close more deals and prevent change orders later. Before pricing, confirm the details that drive system design and savings.
☐ 12 months of usage and the current rate schedule
☐ Export compensation, such as net metering or net billing
☐ Main panel and busbar capacity
☐ Shading and usable roof area
☐ Side-by-side ownership and lease or PPA comparison
Knowing what to include in a solar proposal keeps reps consistent. When homeowners ask whether they can still claim a federal credit, a plain-language explainer on what changed with the solar tax credit in 2026 helps reps answer accurately.
Signed Contract to PTO
A signed contract doesn't guarantee completed-project revenue. Design revisions, permit corrections, utility holdups, and failed inspections stretch timelines, which can complicate financing and raise cancellation risk.
Collect complete site survey data before design starts.
Confirm the interconnection method, such as load side, supply side, or PCS, before permit submission.
Submit complete permit packages to reduce correction cycles.
File interconnection applications as soon as the design is final.
Track every project through inspection and PTO.
This is where GreenLancer fits. Our platform delivers solar permit plan sets, PE-stamped solar engineering, and residential PV interconnection applications so signed projects keep moving toward PTO.
Build a Solar Lead Strategy You Can Measure
The best solar lead source is the one that produces completed projects at a cost your margins can support. Track every source through PTO, qualify technically on the first call, and keep the handoff from sales to design tight.
Once a lead signs, GreenLancer keeps the project moving through design, engineering, and utility paperwork. Solar and EV charging contractors use our platform for:
Solar permit plan sets: Site plans, structural details, electrical diagrams, and equipment specs for residential and commercial PV and battery storage in all 50 states

Solar Leads FAQ
Here are quick answers to common questions installers ask about buying and working solar leads.
Are exclusive solar leads worth the higher price?
Often, but not always. Exclusive leads cost more, but the vendor doesn't resell them to other installers, which can lower your cost per completed project. Homeowners may still collect other quotes, so compare sources by cost per completed project, not price per lead.
What is a live transfer solar lead?
A live transfer is a homeowner who is qualified by a vendor's call center and then connected directly to your sales rep on the same call. You skip the first contact attempt, but you need staffed phones during the vendor's calling hours.
How fast should you contact a new solar lead?
As fast as possible, ideally within minutes. Older cross-industry research on online sales leads found that contact within the first hour sharply improved the chance of qualifying the prospect.
Can you get solar leads for free?
Yes, through referrals, reviews, Google Business Profile optimization, trade partnerships, and reactivating old quotes. These leads cost staff time rather than vendor fees.
Should solar installers buy leads?
Buying leads can make financial sense when your sales team has capacity and your organic pipeline can't keep up. Start with a small pilot and judge results by lead cost per completed project, including cancellations.
What is a pay-per-sale solar lead?
With pay-per-sale solar leads, you pay the vendor only after a deal closes, usually at a higher price per sale. Read how the contract defines a sale, since cancellations and financing denials can affect what you owe.
