Patent attributes
Photovoltaic module feeder assemblies, systems and methods are provided which comprise two rotatable arms, a grabber bar, and at least two gripping pieces. Each arm has a proximal end and a distal end and a plurality of articulation points. The grabber bar is coupled to the distal end of each rotatable arm, and the gripping pieces are connected to each grabber bar. When the rotatable arms rotate to position the grabber bars in alignment with a photovoltaic module, the gripping pieces activate and grip or support the photovoltaic module. The rotatable arms maintain the short sides of the photovoltaic module in a horizontal position by utilizing one or more of the plurality of articulation points. The photovoltaic module feeder assembly may be coupled to a mobile unit having a conveyor and guide rails for moving and holding a pallet of photovoltaic modules. Disclosed methods may be controlled by software that can determine a just-in-time installation schedule.
