Every solar pitch starts with a number the company chose. SunScout starts with yours: NREL's production model for your actual address, your bill, and the honest math — system size, cost range, payback — plus the installers near you with their live ratings, shown as data, not a recommendation.
Free estimate
The estimator above uses NREL's model directly — no AI, no sales assumptions. The box below is for the paper: paste a quote, a lease offer or your bill and get it decoded line by line.
Live estimator — NREL model
Why this exists
Production for your address is a solved problem — NREL's PVWatts has modeled it from typical-year weather for decades, free. What varies threefold is what companies charge on top and what a 25-year escalator lease really costs. SunScout puts the public numbers on the table first.
How it works
ZIP, bill, roof. NREL PVWatts sizes the system and prices the range. Installers near you appear with live ratings.
Paste any quote, lease or PPA. Free tier flags the big-ticket lines; every escalator gets compounded out loud.
On a paid plan: the installer meeting sheet, the two-quote comparison, and the lease-vs-cash math over 25 years.
Plans
Buyer: homeowners with a solar pitch on the kitchen table. Channel: FL solar FB groups, r/solar, Nextdoor — plus the installer plan for companies that would rather sell against honest math.
Everything the estimator knows plus the quote decoder at full depth, for one address.
Quotes keep coming for months. Re-run everything as they land.
For installers who win on honest math: a branded estimator on your site.
All prices in USD, handled by Stripe. SunScout is independent — no installer pays for placement, ratings come live from Google Maps and are shown as data, not endorsement. Estimates are estimates; the signed contract is what binds.
