Home Battery Quote Calculator

Convert a quote into price per usable kWh, separate panel work, and see whether the number needs explanation before you sign.

Quote benchmark

Is the installed price in range?

This is a first-pass screen, not a verdict. A high number can be legitimate if panel work, trenching, service upgrades, or complex backup design are real and itemized.

Why price per usable kWh matters

Battery names do not make quotes comparable. Usable kWh does. Divide the installed price by usable storage capacity, then ask what the extra covers if the number is high. Panel work, service upgrades, trenching, and complex backup-load design can be legitimate, but they need to be itemized.
