Does the Solar Star Attic Fan have an on-off switch or thermostat?
Attics by design are meant to be ventilated year-round. The Solar Star Solar Attic Fan has no switches or
thermostat by design; it runs whenever daylight strikes the solar panel. During the winter proper ventilation
helps prevent condensation from forming within the attic which would cause significant heat loss from the home
if the attic insulation gets wet. A cool, dry attic is the best solution for keeping the heat in the house
during the winter.
Should my Solar Star Attic Fan run during the winter?
Yes - see above on why Solar Attic Fans should run year round.
Does the Solar Star run at night?
There are no batteries on the Solar Star, the unit only runs when daylight is available on the
solar panel. And since at night the sun is down - your attic will not be gaining heat from the
sun and less need of an attic fan. However, this is a good time to run a Tamarack Whole House Fan.
Is the Solar Star Attic Fan quiet?
The Solar Star attic fan is whisper quiet and would likely not be audible from within the house
or in the yard.
What if the roof location doesn't have all-day sun exposure?
The Solar Star attic fan runs best when the solar panel is in direct sunlight. The unit will run
at a reduced speed in the shade (provided sky is bright) but if one has heavy shading for a good portion of the
day an "Add-on Solar Panel" for the Solar Star is a great idea. An extra panel can be placed up to 15'
(4.5m) away (possibly on the opposite side of the roof) from the main roof unit to provide better all day
