SolaTube FAQ Solar Star Attic Fans
|
Does the Solar Star have an on-off switch or thermostat?
Attics by design are meant to be ventilated year-round. The Solar Star attic 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 cold, dry attic is the best solution for keeping the heat in the house during the
winter.
Should my Solar Star run during the winter?
Attics by design are meant to be ventilated year-round. The Solar Star attic 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 cold, dry attic is the
best solution for keeping the heat in the house during the winter.
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.
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 performance.
How much air does the Solar Star move?
The Solar Star is rated to move up to 800cfm (22.5 cmm) depending on sunlight conditions.
