Solar Attic Fan

What is Solar Attic Fan?

Solar Attic Fan is a simple and environmentally friendly fan which is installed on the top of the roof or attic. It can create cool healthier environment in your home as well as save your money. It is totally powered by utilizing free energy of the sun. This is why it is called Solar Attic Fan. This smooth and efficient attic vent is solid, quiet and powerful. Typically, a solar attic fan can improve attic air circulation which contributes to develop a healthy and energy efficient home. Solar attic fans pull hot air and moisture out of your attic. During months of summer season, it keeps your attic cooler and contributes to decrease the load on your HVAC system. On the other hand, during months of winter season, it regulates the increase of moisture and ice blocking. A Solar Attic Fan has significant impact on our environment.



Applications of Solar Attic Fan

Typically, solar attic fans are used in residential homes, industrial buildings and commercial offices. Roof mounted solar attic fans are familiar in residential homes. Gable mounted solar attic fan is attached to your existing gable outlet of your home and is powered by a remote solar panel installed on the roof. Garage outlet has an exhaust system to the solar attic fan which can pull hot air out of your garage easily. Curb mounted solar attic fans are perfect for commercial and industrial building. It attaches to a per-built curb and can exhaust up to 280 square meter per unit.


How does a Solar Attic Fan works?

Roof or attic ventilation is an important feature to maintain your home's structure and save energy. Inappropriate attic ventilation develops moisture which increases the growth of fungus and also causes the deterioration of wood. Appropriate attic ventilation can resist the growth of moisture by creating continuous air circulation. Typically, in an ideal ventilation system, air should enter from roof space and escape outside at roof's ridge.

Sun beats down on the roof surface and heats up the steady air inside the attic. A passive ventilation system is required for homes as per building codes. But, passive ventilation does not provide required pressure to create the force of air through the roof space and outside. This is why, a motorized fan is necessary there. An attic fan installed at the ridge of room can pull air in from outside, force it to move through the entire roof space and escape through the attic vent. During months of summer, a solar attic fan can decrease temperature of roof area up to 40°F. No additional electrical wiring and structural changes are needed in a solar attic fan.


Advantages of Solar Attic Fan

A solar attic fan helps to decrease the interior temperature of a home. During day time, the temperature of a roof can raise up to 160°F or more which causes increasing the interior temperature of your home. An attic fan pulls the hot air from the attic and moves it outside. A solar attic fan can create the inside of a home cooler and more comfortable by venting hot air in the attic outside. 

By decreasing the temperature of a home, it helps air conditioning and home cooling systems to work more efficiently and also contributes to home owner to save energy cost. Because, we know that air conditioning systems consume huge amount of power. If the interior temperature of a home increases, then a air conditioning system also requires more power to cool the inside of a home. Decreasing the gap between the existing interior temperature and the required temperature, an attic ventilation fan contributes to decrease the power consumption of the air conditioning system.

It helps to create a drier and less humid environment in the attic by reducing moisture on the surface.It also reduces the wear and tear and enhances the service life of a roof. Excess heat can cause damage to the roof. Additional ventilation provided by an attic fan can reduce the temperature in the roof area which contributes to enhance roof's lifetime.
