The 4 Seasons 10W solar vent is designed and built for sloped shingled roof applications. The vent works by using the sun's energy to power a fan which pulls excess heat, moisture and humidity out of the attic while promoting healthy air circulation. It can operate from dawn until dusk and has a similar size and shape as traditional roof vents, allowing it to work as a regular passive vent after sun-down.

Because of the sensitive solar panel, the 4 Seasons solar fan can operate even during low light conditions. This vent is often used as an alternative to wind turbines.
