EXACTLY what I was about to write. I sent my drone up to see if I could tell, nope. Stuck my head in the attic, nope, couldn't tell because my entry is in the garage nowhere near the fan. Finally, I went up on the roof and found it was spinning. No idea if it's doing any good or if I wasted $500 (or whatever it was ~6yrs ago). Didn't get it to SAVE MONEY just hoping it would make the A/C work more efficiently with an (allegedly) cooler attic. Probably could have done without it. Up north we had one that could suck you out of the house through the attic entry when the steps were down.
Sounded like a P-51 when it was running but it definitely dropped the attic temp noticeably. It was 110AC obviously not solar.
