I can't say scientifically, but it sure seems to me that this helps keep the attic cooler and hence lower a/c costs. It won't, however, do anything to keep the garage cooler.

The article you are referring to shows a photo of a solar fan and the opening sentence of the article is - "Are solar attic fans worth installing?"
However the point is are attic fans worthwhile regardless of their power source? Many articles say they are not.
However, the first step is to insulate as much as you can. Certainly the door and then the attic space if you can.
