Bifacial is called an advanced double-sided solar panel that transforms sunlight into electrical energy on both – its top and bottom – sides. This is made possible using double-sided solar cells and protective tempered glass on both – top and bottom – sides of the panel. It is very different from a conventional solar panel with opaque backing.
