What Is Difference between Solar Attic Fan And Solar Gable Fan

Solar attic fans and solar gable fans are both types of ventilation systems that use solar power to operate, but they differ in their installation location and design.

Location:

Solar Attic Fan: As the name suggests, a solar attic fan is installed directly on the roof, typically on the high point or in close proximity to the attic. It's designed to exhaust hot air from the attic space.

Solar Gable Fan: A solar gable fan is installed on the gable end of the house, which is the triangular portion of the outer wall between the edges of the intersecting roof pitches. It's also used to exhaust hot air but operates by pulling air out from the gable vent.

Design:

Solar Attic Fan: These fans are usually roof-mounted and have a compact design. They consist of a solar panel, fan blades, and a motor. The solar panel collects sunlight to power the motor, which drives the fan blades to expel hot air from the attic.

Solar Gable Fan: Gable fans are installed on the exterior wall rather than on the roof. They have a similar design to attic fans but are configured to fit in the gable vent opening. The solar panel powers the motor to operate the fan blades, drawing hot air out of the attic through the gable vent.

Installation:

Solar Attic Fan: Installation involves mounting the fan on the roof and ensuring proper sealing to prevent leaks. It requires access to the attic space for wiring and mounting.

Solar Gable Fan: Installation involves mounting the fan on the gable end of the house, typically near an existing gable vent. It may require cutting an opening for the fan and securing it properly.

In summary, while both solar attic fans and solar gable fans serve the purpose of ventilating the attic space using solar power, they differ in their installation location, design, and installation process. The choice between the two depends on factors such as the attic's size, configuration, and the homeowner's preferences.
