Residential and C&I solar companies rarely die of bad engineering; they die of customer-acquisition cost. The lead layer — marketplaces, review platforms, website conversion tools, and paid channels — decides whether an installer’s pipeline is a system or a slot machine. Lead prices run roughly $25 to $300 depending on exclusivity and market, and the spread between disciplined and undisciplined buyers is a business model. This guide compares the acquisition stack on identical criteria.
Review-driven leads: SolarReviews — reputation platform with a lead engine (852k+ leads generated in 2026 by its own count).
Own-website conversion: Demand IQ — instant-estimate funnels on your domain.
Paid channels: search & local ads — the auction you run yourself.
Referral & reputation engine: the compounding channel installers underbuild.
Speed-to-lead stack: where every channel’s ROI is actually decided.
Scope: customer-acquisition platforms and channels for solar installers and developers — lead marketplaces, review ecosystems, website conversion software, and the operational layer that converts inquiries. Proposal and CRM tooling downstream is our solar proposal guide’s territory. Six entries, identical criteria; order follows funnel position, not rank.
Criteria: lead economics (price, exclusivity, intent), control of brand and data, scalability, measurement honesty, commercial model, and the main tradeoff. Unusually for this series, real price ranges are public — cited from platform-published figures (checked October 7, 2026).

Pricing checked October 7, 2026. Most platforms in this category sell quote-based enterprise plans; where we cite figures they come from vendor pages or published third-party comparisons and are order-of-magnitude indications, not offers. Billing basis (per user, per MW, per site) varies by vendor — confirm current terms directly before budgeting.
The Platforms in Detail
EnergySage
The comparison marketplace
Best for: installers who want shoppers already comparing quotes — and accept competing on a transparent stage.
| Lead economics | Marketplace model: consumers request competing quotes; installers pay for placement in the auction |
| Intent quality | High — users arrive to compare real quotes, not browse |
| Brand & data control | The marketplace owns the relationship until you win it |
| Scalability | Deep in active solar markets; volume follows consumer traffic |
| Commercial model | Per-lead/marketplace economics; current rates on platform. Checked October 7, 2026 |
| Main tradeoff | Competing on a comparison stage compresses margins by design — win on reviews and speed or stay out |
- Comparison shoppers close at honest rates precisely because they’re serious — the marketplace pre-filters the merely curious.
- The stage rewards operational excellence: response speed, review depth, and sharp standard offers — capabilities that pay across every other channel too.
- Its consumer-education content machine doubles as the industry’s demand generator — installers benefit from the category marketing they never bought.
SolarReviews
The reputation-to-lead engine
Best for: installers who understand that in a trust-poor industry, third-party reviews are the conversion asset.
| Lead economics | Per-lead sales with exclusivity tiers (exclusive/duo/trio/quad); category pricing it publishes runs ~$25–300 by market and exclusivity |
| Intent quality | Calculator- and research-driven homeowners; review content pre-sells credibility |
| Brand & data control | Your review profile is a durable asset on their domain |
| Scalability | 852,459 leads generated in 2026 by its own published count — volume exists |
| Commercial model | Per-lead; claims $6–8 gross margin per $1 of lead spend for its buyers. Checked October 7, 2026 |
| Main tradeoff | Platform-published performance claims deserve the same skepticism as any vendor’s — measure your own cohort |
- Exclusivity tiers make lead economics legible: the exclusive-versus-quad price spread is the true cost of competition, printed on a rate card.
- Review depth compounds — every earned review improves both marketplace conversion and the Google surface your paid channels land on.
- Its published pricing research (the $25–300 map) is useful market intelligence whoever you buy from — read it before any lead contract.
Demand IQ
The conversion layer you own
Best for: installers with real web traffic who want marketplace-grade conversion on their own domain, their own data.
| Lead economics | SaaS replacing per-lead fees — instant-estimate funnels (address-to-savings) converting visitors you already paid for |
| Intent quality | Your traffic’s intent, converted at materially higher rates than contact forms |
| Brand & data control | Total — your domain, your funnel, your first-party data |
| Scalability | Scales with your traffic acquisition, which becomes the real constraint |
| Commercial model | Subscription; quote-based. Checked October 7, 2026 |
| Main tradeoff | Converts traffic; creates none — pair with channels or inherit silence |
- The strategic pivot from renting leads to owning funnels: every marketing dollar builds your asset instead of a marketplace’s.
- Instant-estimate UX answers the homeowner’s actual first question (what would my roof do?) — the hook static brochure sites never set.
- First-party data compounds downstream: remarketing, referral timing, and the speed-to-lead stack all run better on funnels you instrument.
Paid search & Local Services Ads
The auction you run
Best for: companies ready to buy demand directly — and disciplined enough to survive solar’s brutal click prices.
| Lead economics | Auction CPC/CPL; solar keywords rank among advertising’s most expensive — cost control is the skill |
| Intent quality | Search-captured intent at its peak; LSA adds Google’s screening and pay-per-lead format |
| Brand & data control | Yours entirely — landing on your funnel (see Demand IQ-class layer) |
| Scalability | Elastic with budget; efficiency decays without negative-keyword and geo discipline |
| Commercial model | Media spend plus management; self-serve or agency. Checked October 7, 2026 |
| Main tradeoff | The channel punishes amateurism in cash — tracking and funnel quality decide everything |
- Direct demand capture is the only channel where you set the exclusivity dial yourself — every lead is yours alone by construction.
- LSA’s pay-per-lead format with platform screening imports marketplace economics into your own brand presence.
- The honest prerequisite: conversion infrastructure first — paid traffic into a weak funnel is the industry’s most popular bonfire.
The referral & reputation engine
The compounding channel
Best for: every installer — because the cheapest high-intent lead in solar has always been a neighbor’s recommendation.
| Lead economics | Program costs (rewards, software, review operations) against the industry’s lowest CAC and highest close rates |
| Intent quality | Pre-trusted by social proof — the shortcut no ad buys |
| Brand & data control | Fully yours; reviews live on third-party surfaces but accrue to your name |
| Scalability | Scales with installed base and systematization — the channel installers chronically underbuild |
| Commercial model | Reward structures and review-ops tooling. Checked October 7, 2026 |
| Main tradeoff | Compounds slowly — a system, not a spigot; useless as a rescue plan |
- Referral math embarrasses every paid channel — which is exactly why it deserves systems (asks timed to commissioning, rewards, tracking) rather than hope.
- Review operations are the connective tissue: the same earned reputation lifts marketplace ranking, LSA placement, and closing rates simultaneously.
- Neighborhood clustering is solar’s native virality — every visible install is a billboard; referral programs just collect the rent.
The speed-to-lead stack
Where ROI is decided
Best for: every channel above — because lead response time moves conversion more than lead source does.
| Lead economics | The multiplier on everything: minutes-fast response converts multiples better than hours-slow — across all sources |
| Intent quality | Preserved or squandered here |
| Brand & data control | Your CRM, routing, and instant proposal capability (our proposal guide’s stack) |
| Scalability | Automation-dependent — instant estimates, auto-scheduling, rep alerts |
| Commercial model | Via the CRM/proposal tooling you already buy. Checked October 7, 2026 |
| Main tradeoff | Unowned, like every seam this series keeps finding — assign it or pay for leads twice |
- Channel ROI debates are usually response-time problems wearing a costume — instrument minutes-to-first-touch before blaming any lead source.
- Shared-lead economics (duo/trio/quad tiers) are literally races — buying them without speed infrastructure donates margin to faster rivals.
- The stack is our solar proposal guide’s subject: instant estimates, e-sign, financing in the first conversation — acquisition and closing are one machine.
The Economics Underneath the Lead Price
A lead’s sticker price is the least informative number about it. The working arithmetic is cost per installed watt by channel: lead price, divided by contact rate, appointment rate, and close rate, landed against system size. Run honestly, the spread between channels collapses — expensive exclusive leads and cheap shared ones often converge once speed and competition are priced — and the real differentiators emerge: funnel ownership, response infrastructure, and reputation assets that improve every channel at once.
The market-structure story mirrors this series’ recurring pattern: marketplaces aggregate demand and publish the category’s only price transparency; conversion software shifts power toward installers who own traffic; and platform-published performance claims (852k leads, 6–8x margins) are useful signals that still deserve cohort-level verification by every buyer — vendor math is marketing, your CRM’s math is truth.
Building the Acquisition Portfolio
Treat channels as a portfolio with explicit allocation logic: marketplaces and shared leads for baseline volume while operational muscle builds, paid channels as owned funnels mature enough to convert them, referral systems compounding from the first commissioning onward. Rebalance quarterly on cost-per-installed-watt, never on lead price — and sunset nothing emotionally; channels decay and recover with market cycles.
The sequencing discipline for a growing installer: speed-to-lead infrastructure before any volume purchase, conversion funnel before paid traffic, review operations before marketplace scaling — each layer multiplies the next. The pattern is this series’ oldest lesson in acquisition clothing: the seams (response time, funnel, reputation) outvalue the platforms they connect.
Kurums Match: Which One Fits You?
Pick the statement that sounds most like your situation.
We’re a newer installer that needs volume now.
Shared-lead tiers (SolarReviews-class) and marketplace presence (EnergySage-class) buy pipeline while you build — but stand up speed-to-lead response first; shared leads are races you must actually win.
We have traffic and a brand but mediocre conversion.
Demand IQ-class instant-estimate funnels on your domain, then paid channels pointed at them. Measure funnel conversion before and after — the uplift typically outpays the subscription immediately.
Our CAC keeps climbing and channel reports contradict each other.
Standardize one metric — cost per installed watt by channel, CRM-sourced — and instrument minutes-to-first-touch. Most contradictions dissolve; what remains is a real portfolio decision, made quarterly.
We’ve installed hundreds of systems but referrals just… happen.
That is the underbuilt compounding channel: systematic asks at commissioning, rewards, review operations, neighborhood campaigns. The installed base is an asset — collect its yield deliberately.
Frequently Asked Questions
How does this connect to your solar proposal software guide?
This guide fills the funnel; that one converts it — and the handoff (speed-to-lead, instant estimates, e-sign in the first conversation) is where acquisition spend is saved or squandered. Buy them as one machine.
What do solar leads actually cost?
The category’s own published range runs roughly $25–300: call-center shared leads at the floor, exclusive screened leads in competitive metros at the ceiling, with exclusivity tiers (solo through quad-shared) pricing the competition explicitly. The number that matters is cost per installed watt after your conversion rates.
Marketplace leads or our own funnel — which is better?
Sequencing, not either/or: marketplaces monetize demand you can’t yet attract; owned funnels compound once traffic and brand exist. Mature installers run both and rebalance on measured cohort economics — the portfolio, not the pick, is the strategy.
Do these channels work outside the US residential market?
The architecture travels (marketplaces, review platforms, conversion funnels exist across Europe and Australia); the specific platforms here are US-centric. C&I and utility-scale acquisition runs on entirely different rails — relationships, RFPs, and the origination stacks our siting and interconnection guides describe.
