Hi Brad!
Thank you for your message; I'm hoping others can provide more insight on this, however, I did want to share that ASES put out an article titled "Solar for Zero Down: Too Good to Be True?" https://ases.org/solar-for-zero-down-too-good-to-be-true/
I hope this helps!
Thank you for being a member of our solar community!
With gratitude,
