Natural Light SAF65G Solar Gable Fan
#1 in Gable mountFull review
The strongest gable fan here, for a big attic with a large gable vent. The price only makes sense if the lifetime warranty matters.

OmniPV OP-SAF-40 Hybrid Solar Attic Fan
#11 in Roof mountFull review
A hybrid roof fan with a thermostat for a medium attic at a fair price. The newer 50 W model is the better buy if the price gap stays small.
