Frequently asked questions

Everything you need to know about turning utility bills into solar recommendations with BillToSun.

Which utility bills does BillToSun support?
BillToSun reads bills from major providers including Southern California Edison (SCE), LADWP, PG&E, and SDG&E. It handles both monthly and bi-monthly billing formats and isolates electricity usage from combined water, sewer, and trash statements.
How accurate is the bill reading?
The tool anchors to the exact figures printed on the bill — such as the total electricity used and average daily kWh — rather than estimating. The same bill always returns the same numbers, so your quotes stay consistent.
How long does an analysis take?
Most bills are analyzed in under ten seconds, so you can get a solar recommendation while you're still in the appointment.
What does the solar recommendation include?
You get the recommended system size in kilowatts, panel count, estimated annual production, financing and savings estimates, battery storage sizing, and net-metering (NEM) guidance.
Is my customer's data safe?
Yes. Raw bill documents are deleted after processing — only the structured energy data needed for the recommendation is stored.
Do I need any special equipment?
No. A phone camera or a PDF upload is all you need. BillToSun runs in your browser.
