Solar Attic Fan
solar attic fan is quickly becoming the standard for attic fans. In
most homes attics are unfinished, but filled with insulation. During
the summer they can reach temperatures that are much higher than outdoor
temperatures, especially on houses with black roofs which are most common.
A hot attic will transfer that heat down into the living areas of the
house which will drastically increase cooling bills. An improperly ventilated
attic can also cause structural damage because of trapped water vapor.
A solar attic fan can solve many of those problems. It allows air to
circulate which prevents the interior of the attic from superheating.
With no ventilation an attic can reach over 170 degrees F which can
contribute to the ruining of insulation, shingles and wood. Moisture
can destroy a house quicker than any other natural force. A barn can
be torn down just by cutting a hole in the roof and waiting for a couple
of freeze/thaw cycles. Attic fans circulate the air preventing excess
A solar attic fan works by converting the suns photons into usable
current. Most attic fans are totally self sufficient, they generate
all the power they need to run the fan and contain batteries to store
extra power during the night. Since they are self contained, there is
no wiring that has to be done, simply install it onto an existing vent,
or cut a new one. Small panels can even be hooked up to existing vents
converting them to solar power.
