Everything you need to close more solar deals

BillToSun turns a customer's utility bill into a complete, accurate solar recommendation in seconds — usage, system size, financing, batteries, and net metering.

AI utility bill scanning

Snap a photo or upload a PDF of any Edison, LADWP, PG&E, or SDG&E bill. BillToSun reads the provider, rate plan, billing period, and exact usage history automatically.

Instant solar system sizing

Get a recommended system size in kilowatts, panel count, and estimated annual production from real usage — not rough guesses.

Financing & savings estimates

Show customers system cost, the federal tax credit, monthly loan payments, projected new bill, and lifetime savings on the spot.

Battery storage sizing

Right-size battery storage to a home's essential loads and backup needs, with estimated monthly add-on cost per unit.

Net metering (NEM) analysis

Automatically classify NEM 2.0 vs NEM 3.0 by utility so reps know when a battery is essential to maximize savings.

Privacy by design

Raw documents are deleted after processing — only structured energy data is stored.
