Spatially-shaped photovoltaic screen system
A photovoltaic screen system is an integrated structure disposed over an opening in a wall of a building. The integrated structure includes a screen that is permeable to light and air, a photovoltaic (PV) element coupled to a portion of the screen, and a frame coupled to the screen and PV element. The frame is adapted to be attached to the building and includes a portion occupying a three-dimensional geometry extending outward from the opening in the wall so that the screen and PV element lie along a perimeter of the three-dimensional geometry.
