According to Bob F :

They told me that over the course of a year, their production about
equals their usage, so they pay nothing for the electricity. I'm sure
there is a base charge, but didn't ask about that.

That's quite remarkable. Do you have any idea of what the output
of the thing was?

No idea. The panel area was maybe 10 x 10 feet if I remember correctly.
And they are probably very conservative in their use.
