A system includes a plurality of photovoltaic modules, each having at least one solar cell, an encapsulant encapsulating the solar cell, a frontsheet, and a backsheet. The encapsulant and the frontsheet are transparent. The backsheet includes a first section and a second section juxtaposed with the first section. The first section is transparent and the second section is non-transparent. A first end of the frontsheet, a first end of the encapsulant, and the first section of the backsheet form a transparent portion. A first photovoltaic module overlays at least a portion of a second photovoltaic module. The transparent portion of the first photovoltaic module overlays at least a portion of the at least one solar cell of the second photovoltaic module.
