As we mentioned, an intact whirlybird should not leak; however, there can be issues arising from the improper fitting of the vent—or from simple wear and tear—that can lead to a leak. The whirlybird does not have a motor, but because of its special shape, its blades will still spin when it falls. They do this by dragging in cooler air from outside and expelling the inside hot air. While solar panel manufacturing costs are reducing, a quality motor and solar panel will always be the most expensive components of a solar roof ventilator. First, if the shed is made of wood, it’s likely that the moisture level in the air is too high. Remember to record your results in your data table, in the row for "1" paper clip. If the air being forced out by the fan is coming entirely from the outside, then yes, powered attic fans can be extremely effective.
