Solar attic fan is a ventilation device that uses solar panels to absorb sunlight and convert solar energy into electrical energy. Solar fans are mainly installed on the roof to allow people to ventilate the attic and adjust the temperature of the hot air to rise in the attic, thereby protecting the service life of the attic. In summer, the temperature of the roof can be lowered, and ventilation and moisture removal in winter can reduce the growth of mold. Let us look at some of the benefits of installing solar attic fan.
