Velux 22-1/2 x 46-1/2 Inch Laminated LowE3 Solar Powered Venting Curb Mount Skylight from the VCS Collection

The Solar Powered "Fresh Air" Skylight features a solar panel that captures any available daylight and uses it to recharge a highly efficient, fully concealed battery powered operator and control system. The battery powered operator is the power source that opens and closes the skylight. A rain sensor is built in to close the unit in the event that inclement weather arises while you're away.
