Frequently Asked Questions

Does this account for solar tax credits?

No, this calculates loan payments only. Apply any federal or state tax credits to reduce your system cost before entering it.

Is a bigger down payment worth it?

A larger down payment reduces your principal, monthly payment, and total interest paid over the loan term.

What loan terms are typical for solar financing?

Solar loans commonly range from 10 to 20 years, with longer terms lowering monthly payments but increasing total interest.
