Meet the VELUX No Leak “Fresh Air” Skylight: a solar-powered solution that brings natural light and fresh air into your home. It does not require any wiring and relies on the power of the sun to open and close. You also get 3 layers of water protection.
The included solar panel captures sunlight and recharges the battery for this system. It works on cloudy days and with indirect light. The Skylight automatically closes if the battery gets low. There is also an integrated rain sensor available. Like what you see? More information is available here.
