Solar Attic Fan: How It Works?

Takumi Fujiwara : Solar Attic Fan is powered by the sun and the sun only. It is also increases fresh air circulation which reduces vapor builds up generated by everyday activities like showering and cooking. A solar attic fan works pretty much like you’d expect it to. The fan itself is installed near the ridge of your home’s roof, and is then connected to a set of low powered photovoltaic solar cells that provide the fan with enough electricity to get the fan spinning when the sun is shining.

A solar attic fan uses photovoltaic panels to convert sunlight into electrical power. The electricity generated is used to turn a fan motor, exhausting air from the attic of a home.

How it works?

%Attic Exhaust Fans%

A solar attic fan, converts the solar energy to electrical energy, stores it and drives a motor which in turn drives the vanes of the fan to generate air, exhaust or intake. During the day, when there is solar power, (sunny day), the solar energy (rays) from the sun is stored for night consumption. (Energy saving). That is the real purpose of a solar attic fan.

The attic becomes warmest when the sun is the strongest. A solar attic fan runs the hardest when the sun is strongest. Everyday home activities such as cooking and showering create moisture which collects in the attic and promotes mold and mildew growth, reduces the effectiveness of insulation, and attacks the wooden attic structure. Year round fresh air circulation from a solar attic fan removes this moisture and prevents moisture related problems.http://solaratticfan.blogspot.com/
