That advice is excellent. You should have an on/off switch, and you do not want to run it when you are running the a/c, ever. You are right, that would just pull all the cooled air from the house. Attic fans were used prior to having a/c in homes because they do cool the house down, but they are not meant to be used when a/c is used.

Edit: I don't think that it matters whether it runs with solar or not, as long as you are able to turn it off when needed---and a solar powered fan should not be a problem to turn off.
