A method of forming a longitudinally continuous photovoltaic (PV) module includes arranging strips of thin-film PV material to be spaced apart from and substantially parallel to each other. The method also includes laminating a bottom layer to a first surface of the strips of thin-film PV material, the bottom layer including multiple bottom layer conductive strips. The method also includes laminating a top layer to a second surface of the strips of thin-film PV material opposite the first surface, the top layer including multiple top layer conductive strips. Laminating the bottom layer to the first surface and laminating the top layer to the second surface includes serially and redundantly interconnecting the strips of thin-film PV material together by connecting each one of the strips of thin-film PV material to a different one of the bottom layer conductive strips and a different one of the top layer conductive strips.
