How it works

Three steps. No account required. No sales rep will call you.

01

Google Solar maps your exact roof in 3D.

02
Modern solar panels on a residential roof

AI runs the math

Your real Duke Energy tier rate. Not a ZIP average.

03

See your number

One honest dollar figure. No sales calls. Ever.

Most solar sites are sales funnels.
We're a calculator.

Every competitor uses zip-code averages and flat rate estimates. We connect directly to the same APIs that solar engineers use when they design a real system.

Real utility tier rates

From OpenEI's national database. We use the tier you're actually on — not the blended average that understates your savings by 40%.

Address-level roof data

Google Solar Building Insights maps the 3D geometry of your specific roof. Panel count, shade patterns, and usable area — not a county average.

NREL sun-hours

National Renewable Energy Laboratory production data for your exact zip code, updated annually.

No vague ranges

We don't say "you could save $500–$5,000." We say "$2,840/year based on your address and current utility rate." That's the difference.

Solar installer meeting a homeowner

The solar industry has a phone-call problem.

The typical solar funnel sells your number to five installers before you even see a number. We built the opposite of that.

No pressure

Your savings estimate is yours the moment you drop your address. We never initiate a sales call.

No pre-checked boxes

Opting in to installer quotes is a deliberate choice you make — not a box we quietly checked for you.

Phone opt-in only

We don't collect your phone number to run the estimate. If you want installer quotes, you choose to provide it.

Currently serving NC + SC

We launched here because the math actually works — top-tier rates in the Carolinas rival California, at a fraction of the advertising cost.

Why the Carolinas? Duke Energy and Dominion customers in NC and SC pay some of the highest tiered rates in the Southeast — making solar ROI faster and more predictable than most other markets.

Every “get a quote” site sells your number to five installers. We don't.

How we compare

Most solar estimators trade precision for leads. We don't.
