Solar Roof Vents vs. Wind Ventilators

Wind ventilators are, effective but they are slow. Wind ventilators depend on wind speeds to power their turbine spins. When wind speeds are low, then the rate at which they extract heated air from living spaces is slower.

Solar roof ventilators, on the other hand, move at speeds seven times that of the wind whirlybird. These speeds enable the air flow capacity into the house to be higher providing air conditioning for the home. Hot summer afternoons are now more relaxed with the solar-powered roof vent.

While wind-powered ventilators have no running costs, solar roof ventilation helps reduce energy bills by cooling the house, therefore, taking off the air conditioner costs. Roof ventilation work can be tasking, but with the right ventilator, you get to enjoy summer months comfortably. Other differences include:

1. A small solar roof vent has the power to extract ten times more hot air than a customarily sized whirlybird ventilator.
2. There is no noise from the solar roof ventilator. Wind-driven ventilators sometimes make sound especially when it’s very windy
3. There is no correlation to the difference in their cooling effects. The solar roof vents are noticeable almost immediately as opposed to the wind driven ventilators.
