I will agree that electric attic vent fans are more powerful, but they are loud, consume expensive electricity, and typically run far into the evening/early AM. I know that my Solatube Solar Star solar fans, which I used to replace my electric fans, are whisper quiet and have already paid for themselves. I know the Solar Star fans have a proven track record of highly efficient operation with little/no maintenance issues.
