You buy solar to use the electricity for yourself.<
That would require a battery installation. I’m guessing in the $20k range.
It sounds like the lady was expecting to hook to the grid, use solar to power when the sun shines whilst selling the excess to the power company, then using from the grid at nightand and cashing in on a tax credit. It would pay back in the 11-13 year range.
Full off-the-grid solar takes longer to pay off.
As an added non-bonus, the batteries are only warranted for 10 years.
This is all pie in the sky stuff.

“That would require a battery installation”
I don’t recall the fine details, but out here in California, the Assy. took away the incentive to put solar on your roof this past April UNLESS you add on the 15 - 20k battery wall. Now you are in the 40k neighborhood for the total system.
It's been decades since I ran the numbers for myself, but it seems to me that by the time the system pays for itself, you'll need new equipment. In her case, she said $30,000 initially.
My neighbor heated his swimming pool with solar panels, but about once every month or so I'd see the solar repair people parked in front of his house. I doubt that he ever broke even.
