How Do Solar Attic Fan Work?
Solar attic fans work by converting energy from the sun into electricity that powers a small electric motor. The motor turns a fan blade, which draws hot air from the attic and vents it to the outside. As the hot air is removed, cooler air is drawn into the attic through vents in the eaves, soffits, or gable ends of the roof.
Solar attic fans have a solar panel that is usually mounted on the roof. The solar panel collects energy from the sun and converts it into direct current (DC) electricity. This electricity is stored in a battery so that the fan can run even when the sun isn't shining.
When the attic temperature reaches a set point, typically around 80-85 degrees Fahrenheit, a thermostat activates the fan. The fan then runs until the attic temperature drops below the set point. Some solar attic fans also come with a humidistat to turn on the fan when the humidity level in the attic reaches a certain level, which helps prevent mold and mildew growth.
Solar attic fans are an effective way to increase ventilation in your attic, which can help reduce energy costs by preventing excessive heat buildup in your home. Additionally, they are a sustainable and eco-friendly option because they use renewable energy from the sun.
