Residential solar

Sun-hours, utility-bill tier, roof pitch, income-vs-bill fit, incentive-eligibility, EV-in-driveway boost.

Solar salespeople knock on doors for a living. The economics only work on specific homes: south-facing roof, low tree cover, a utility bill big enough that 20 years of panel-payback beats status quo, and an income that can absorb a loan or lease. Most lists ignore all of it.

LeadWarmer pulls the actual solar-readiness signals — roof age, sun hours per day by address, utility bill tier from block-group patterns, state + federal incentive stack, and EV-in-driveway boosts that nearly double propensity.

The 14 correlations

What we pull for residential solar.

Two layers. Per-lead signals rank the rows on your list. Market & contextual drivers — regulation, incentives, rates, weather, and migration — set the backdrop that decides when a whole segment heats up. The top 20% bubble up; the cold rows get deprioritized until a signal shifts.

The workflow

How LeadWarmer works for residential solar.

No new data to buy and no integration project. You bring the residential solar list you already have; we score it against the signals that decide who's ready.

Step 01
Upload your list

Drop a CSV of your residential solar leads — CRM export, purchased list, or scraped names. No schema to match.

Step 02
We score 14 correlations

Every row is scored on the residential solar signal set — starting with roof age, sun hours / day, and utility bill tier.

Step 03
Call the ranked sheet

You get a prioritized call list with the reason each lead scored where it did — so the 20% worth calling today rise to the top.

Residential solar FAQ

Questions residential solar teams ask.

How do I qualify a solar lead before knocking?

LeadWarmer scores each address on the signals that make solar pencil out — roof age and pitch, address-specific sun hours, utility-bill tier, incentive eligibility, and EV-in-driveway boosts — so you skip the roofs that will never work.

Why do utility bills matter for solar leads?

The economics only work above a certain monthly bill. LeadWarmer estimates each home's utility tier from block-group patterns and prioritizes homes where payback beats the status quo.

Does it account for incentives?

Yes — it stacks state and federal incentives per lead, which can change the entire pitch and affordability.

What makes an EV household a better solar lead?

EV households convert on solar at a notably higher rate. LeadWarmer flags EV-in-driveway signals so you prioritize them.
