How Many Solar Attic Fans Do I Need?

The amount of solar attic fans a home needs will ultimately depend on many factors. Vaulted ceilings, obstructions, and the amount of existing ventilation from soffit vents, ridge vents and gable vents should all be considered. This will make determining the quantity, type, and placement of solar fans much easier and more effective.
