  • Publication number: 20240146234
    Abstract: A system includes first, second and third photovoltaic modules on a rood. Each module includes an upper edge, a lower edge and at least one solar cell. Lower edges of the cells of the first and second modules are offset from lower edges of the first and second modules. Upper edge of the cell of the second module is offset from the upper edge of the second module. The upper edge of the cell of the third module is offset from the upper edge of the third module. The first module overlays the second module. The lower edge of the cell of the first module is substantially aligned with the upper edge of the cell of the second module. The second module overlays the third module. The lower edge of the cell of the second module is substantially aligned with the upper edge of the cell of the third module.

  • Publication number: 20230203815
    Abstract: A system includes a plurality of roofing modules and a plurality of photovoltaic modules. The roofing modules include a first layer and a second layer. The first layer has a first surface that is textured. The roofing modules are configured to be installed on the roof deck of a structure proximate to the photovoltaic modules. An appearance of the roofing modules aesthetically matches an appearance of the photovoltaic modules when viewed from a vantage point located at a ground level of the structure.
