Remington Solar20-Watt 1,280 CFM Gable Mount Solar Powered Attic Fan

I’m in a hurricane prone area - will the solar panel stay mounted? And must the wire from solar panel to fan run on outside of house?

can seperate solar panels be purchased and wired into fan so you can get the full range of the sun from morning thru evening what are the cost

How is this product better or worse than the quietcool 40 watt solar, gable-mount attic fan? seems quietcool is easier to install.

Is there a power shutter for the 23x23 x 6in?
