Three details that change the comparison

01

Cash price

Ask for the project’s cash price before incentives. Keep it separate from the amount financed, the monthly payment and the total of payments.

02

What’s included

Check the panels’ rated DC capacity and ask for separate prices for storage, roof work and electrical upgrades. A battery line item does not tell you which circuits have backup.

03

Bill assumptions

Check the utility rate used in the estimate and the mode assumed for your battery. Ask for the first-year bill estimate and the assumptions behind it.
