This guide is for solar installers, solar sales organizations, multi-trade home services companies and buying desks deciding where their homeowner requests should come from. It covers how solar lead companies operate, what official data says about where residential solar demand comes from, the channels that reach homeowners, how to compare sources, and what a usable solar lead contains.
Key points
- Sunlight, incentives and net metering rules shape where homeowners install solar, according to the U.S. Energy Information Administration.
- A solar sale takes several steps after the lead, so sources are judged on cost per signed contract, not cost per lead.
- Ads that promise what a homeowner will gain produce requests that are hard to close and claims that are hard to defend.
- Every bought lead should arrive with its consent record and the street address of the home.
How solar lead generation companies work
A solar lead begins when a homeowner sees an ad, a search result or a page about solar and decides to ask for more information. The lead generation company controls that ad or page, asks the homeowner questions about the home and the project, shows consent language, records the answers and the consent, and sends the request on to a company that sells or installs systems.
Solar lead companies come in several types. The type tells you who owns the lead, who else receives it and what you are paying for:
| Type | What you pay for | Who receives the lead |
|---|---|---|
| Marketing agency | A fee plus ad spend to run campaigns under your brand. | Your company only, and you own the ad accounts if the contract says so. |
| Pay-per-lead generator | Each lead that fits the criteria you set. | Your company, or several buyers when the lead is sold shared. |
| Lead broker | Each lead, usually priced through ping/post bids. | Whichever buyer’s filters and bid win it. See what a lead broker is. |
| Contractor marketplace | Leads or a subscription, depending on the platform. | Often several local companies at the same time. |
| In-house marketing team | Staff, ad spend and software. | Your company only. |
Many solar companies mix these. A common pattern is an in-house search and referral program in the core market, plus bought leads in areas where the company’s own marketing is thin or where a new crew has just started.
What drives homeowner demand for solar
Sunlight comes first. The U.S. Energy Information Administration explains that the amount of solar radiation a place receives depends on latitude, climate and weather, and that lower latitudes and dry climates generally receive more. Shade from buildings, trees and hills changes it again for a single roof. The National Laboratory of the Rockies (NLR, formerly NREL) publishes the PVWatts calculator, which estimates what a grid-connected system would produce at a given location from typical-year weather data. With PVWatts default settings (a 1 kW fixed array facing south at a 20 degree tilt), average daily solar radiation on the panels is about 6.5 kWh per square meter in Phoenix, 4.5 in Columbus, Ohio, and 3.1 in Anchorage, in a run made for this site in October 2026.
Policy comes next. The same EIA page says that the availability of financial and other incentives is a major factor in where solar systems are installed, and that net metering has been especially important for systems on homes and businesses. Those rules differ by state and change over time, so a market that produced steady requests one year can behave differently the next. The federal credit is one example: as of October 9, 2026, the IRS page for the Residential Clean Energy Credit states that the credit is not available for any property placed in service after December 31, 2025.
The installed base keeps growing, which also brings requests for batteries, expansions and replacements. EIA reports that small-scale grid-connected PV systems generated about 93 billion kWh in 2025, up from about 18 billion kWh in 2016, and its Electric Power Monthly table 6.2.B estimates small-scale solar PV capacity at 62,840 MW in July 2026 against 56,307 MW in July 2025 (preliminary values, released September 24, 2026). Small-scale demand is uneven: EIA notes that California accounted for nearly 37% of small-scale PV generation in 2025.
Two features of the home matter as much as the state. The homeowner has to own the property to agree to a system on the roof, and the roof itself has to be in a condition and orientation an installer will work with. Neither shows up in state data, which is why lead forms ask about ownership and why installers check the roof before they quote.
Solar lead generation channels compared
Each channel catches homeowners at a different stage. Search reaches people already comparing companies, social and display ads reach people who had not planned to look, and referrals come from customers who already have a system.
| Channel | Who it reaches | Main cost | What to watch |
|---|---|---|---|
| Search ads | Homeowners searching for solar installers or quotes | Cost per click | Clicks from renters, job seekers and people outside your area |
| Social ads | Homeowners who have not started looking | Cost per click or impression | Lower intent; claims in the ad set expectations the sales team must meet |
| Your website and SEO | Homeowners researching solar over weeks or months | Content and site work | Pages need local detail, real project photos and a short form |
| Map listing and business profile | Homeowners comparing local installers | Time on the profile and reviews | Listing rules about addresses and service areas |
| Referrals from customers | Neighbors and friends of people with a system | Time, sometimes a referral reward | Slow to scale and uneven by area |
| Door-to-door and events | Homeowners in a chosen neighborhood | Staff time and travel | Local permit rules for door-to-door sales and the consent for any follow-up calls |
| Bought leads | Homeowners who asked to be contacted about solar | Price per lead | Ad claims behind the lead, exclusivity, consent and returns |

How to compare solar lead companies
Put the same questions to every seller and compare the written answers. A sales call is not evidence; a sample lead with its consent record is.
- Which ads and pages produce the leads? Ask to see the ad copy and the landing page. Solar ads that promise what the homeowner will gain bring in people expecting something the installer cannot offer.
- Who else gets each lead? An exclusive leadExclusive leadA lead delivered to one buyer and not resold to others. Glossary goes to one buyer and a shared lead to several. Exclusive vs shared leads explains the trade-off.
- What is in the consent record? The opt-in languageOpt-in languageThe consent disclosure shown next to the submit button on a lead form. Glossary shown, the company it names, the timestamp, the IP address and the page URL, for every lead.
- Which filters can you set? ZIP code, homeownership and project type at least, plus daily caps.
- How quickly does the lead arrive? Homeowners often ask several solar companies in the same week, so minutes count.
- What can be returned, and how? Wrong numbers, duplicates and leads outside your filters are the usual reasons. Get the terms in writing before the first batch.
How to evaluate lead suppliers turns these questions into a checklist, and buy leads vs generate in-house helps decide how much of your pipeline should come from outside sources at all.
Measuring a solar lead source
A solar sale passes through more steps than most home services jobs, and each step can lose the homeowner. Track every source through the same stages so you can see where it falls short:
| Stage | What it tells you about the source |
|---|---|
| Contacted | Whether the phone numbers work and the homeowner remembers asking. |
| Qualified on the call | Whether the homeowner owns the home and the roof looks workable. |
| Site visit or design call booked | Whether the request reflected real interest. |
| Proposal delivered | Whether the home suits a system the company sells. |
| Contract signed | The figure that decides whether the source is worth what it costs. |
Because a solar sale can take weeks, judge a source on a full batch that has had time to close, not on the first few days. Use the lead cost calculator to turn your own numbers into a cost per signed contract, and give every lead a source field so the comparison is possible.
Consent, calling rules and solar ad claims
A bought solar lead can be used only in the way the homeowner agreed to be contacted. TCPA compliance for solar leads covers the federal consent rules for solar calls and texts, and one-to-one consent explains why the company named in the consent matters. Keep the consent record with the lead, as record keeping describes, and call inside the hours in telemarketing calling hours by state.
Solar advertising draws close attention from regulators because homeowners make a large decision based on what they were told. Claims about what a homeowner will gain, about tax treatment or about incentives with no official source are the usual problems. The publisherPublisherA company or individual that generates leads, usually through websites, ads or content, and sells them to brokers or buyers. Glossary guide solar ad claims to avoid sets out the rules and their official sources.
This page is general information, not legal advice. Ask your own counsel how consent, calling and advertising rules apply to the way your company markets solar and contacts homeowners.
What a usable solar lead contains
From any of these sources, a lead a sales team can work answers the questions asked on the first call:
- Homeownership, because an owner can agree to a system and a renter usually cannot.
- Street address, city, state and ZIP code, so the team can check the roof and the service area before calling.
- Project type, in general terms, such as a new system or battery storage.
- Timeframe, so homeowners ready to move soon are called first.
- Contact details with a working phone number and email address.
- The consent record: opt-in language, timestamp, IP address and page URL.

Frequently asked questions
What do solar lead generation companies actually sell?
Homeowner requests for information about solar, each with the homeowner’s answers and consent to be contacted. Some sell each lead to one buyer, some to several, and agencies run campaigns in the buyer’s own name instead.
Is Summit Leads a solar marketing agency?
No. Summit Leads is a lead brokerage, not a marketing agency: it buys solar leads from lead generators and sells them to buyers by real-time ping/post, with filters and routing agreed during onboarding.
Why do solar leads take longer to turn into sales than other home services leads?
A homeowner usually needs a site visit or design call, a proposal and time to decide before signing, and many compare more than one company. That is why sources should be judged on a full batch that has had time to close.
Does sunlight decide where solar leads come from?
It is one factor. EIA names incentives and net metering rules as major factors too, and each home still needs an owner who can agree and a roof that suits a system.
