WattFoundry
Where watts get cast into proposals.
The commercial solar proposal platform that turns four hours of busywork into eight minutes of clicks.
The problem
4 hours
That's how long your best rep spends building one commercial solar proposal.
Not pitching. Not closing. Copy-pasting bills, chasing rate schedules, sizing arrays in a modeling tool, running loan math, and re-building the PDF for the fourth time this week.
Where the hours go
Every commercial deal, every rep, every time.

WattFoundry
Now it's 8 minutes.
One platform runs the full pipeline. Your rep pitches. The engine builds. The customer opens a link and clicks Accept.
The flow
From first call to signed proposal.
Four stages. No context switches. No reformatting between tools.
01 · INTAKE
Drop the bills
Customer name, address, twelve months of utility bills. AI parses everything.
02 · DESIGN
Click the roof
Satellite imagery, pre-placed panels, keep-out zones. Reps click faces in priority order.
03 · BUILD
Engine runs
Modeling, financing, incentives, documents. Eleven steps in five minutes, no rep time.
04 · DELIVER
Customer opens a link
Branded web proposal. Tap to accept, decline, or ask. You're notified in real time.
01 · Intake & bills
Drop a folder of bills. Done.
Reps don't need to be analysts. The platform is.
- AI vision OCR handles scanned PDFs, phone photos, and utility portal exports.
- Thirty-plus US utilities out of the box — PG&E, SDG&E, SCE, APS, SRP, Xcel, Duke, Con Ed, PacifiCorp, Idaho Power, and more.
- Auto-detects rate schedule, time-of-use tier, and demand billing.
- Twelve months of usage, demand peaks, and cost normalized into one profile in seconds.
- CSV and Excel multi-meter imports for portfolios of five, fifty, or five hundred meters.

02 · Satellite roof designer
Click the roof. Watch panels land.
Real sun data, real imagery, real production. Not averages, not guesses.
- Google Solar API pre-places every viable panel on every roof face — nothing to draw manually.
- Reps click faces in priority order; target kW size resolves automatically.
- Paint keep-outs around vents, HVAC, skylights with a drag.
- Four mount types: roof mount, ballast, ground mount, carport — one tool, all configurations.
- LiDAR shade analysis as an add-on for anything the satellite can't see clearly.

- Tap to accept, decline, or ask a question. Response lands in your inbox immediately.
- Every view, open, and interaction tracked. No more "I never got the email."
- Signed proposals auto-promote to your pipeline with full customer metadata intact.
- Shareable URL or branded PDF fallback if the customer really wants one.
