Battery add-on estimate example
A battery is a backup promise. Say which circuits are backed up and for roughly how long.
"add 13.5 kwh battery to existing system, backup critical loads panel, gateway, permit and utility notice incl, mount in garage, 2 day install"
Example figures for a typical battery add-on job. Not a quote. Every line on the estimate came from the notes above. Nothing was added.
What to spell out on a battery add-on bid
- Battery capacity and model.
- The circuits that go on the backup panel, by name, and that the rest of the house is not backed up.
- That runtime depends on what is on, and a rough figure for the listed circuits.
- Who notifies the utility and whether the existing system permit needs an amendment.
Do not let the production number read like a promise. Label it an estimate, say what it assumes, and put the equipment warranty terms next to your labor warranty.
The parts of this estimate
- Scope of work. 5 lines, one thing each, in the order the work happens. What is not included is on the list too.
- One price. $14,200. Not a formula, not a range. The scope explains the number.
- Timeline. 2 days, after permit. Including dry time, cure time, or permit time, so the customer plans around it.

- Warranty. 5 years on workmanship, manufacturer warranty on the battery.
- A way to accept. The customer types their name and signs with a finger on their phone. Legally binding under the E-SIGN Act, and recorded with the date, time, and the exact estimate they agreed to.
Questions solar installers ask about this bid
List the backed-up circuits?
Yes, every one, in the scope. "Fridge, well pump, two bedroom outlets, wifi" is a promise the customer can check.
Deposit?
Twenty percent, because the battery is ordered for this house and the install is scheduled around delivery.
Is this a real quote?
No. The numbers are example figures for a typical job so you can see how a complete estimate reads. Your price is yours.
Can my customer sign this on their phone?
Yes. An estimate sent from BidWriter Pro opens as a link. The customer reads it, types their name, signs with a finger, and pays the deposit by card. You get an alert when they open it and when they sign.
