How is the Solatube effected by the weather, such as cloudy or rainy days?
The Solatube is designed to work well beneath cloud coverage– there is some light loss as compared to a sunny day, but it is effective on cloudy days, even when located on the north side of the house. Not only will the Solatube function satisfactorily on a cloudy day, it will still bring in a measurable amount of light during a rainfall!
