An integrated cell and circuit interconnection for photovoltaic devices is disclosed. Interconnection componentry includes conductive material utilized to connect a negative terminal of a photovoltaic cell of a substring of a photovoltaic device to a positive terminal of a photovoltaic cell of another substring of the photovoltaic device to electrically connect the cells together. Certain interconnection componentry include extension portions that extend beyond the edge of the photovoltaic cells to which the interconnection componentry are connected. The extension portions are configured to connect to an electrical circuit of the photovoltaic device and connect the substrings to which the extension portions are attached to other substrings of the photovoltaic device. The interconnection componentry and extension portions facilitate bypass diode integration into the electrical circuit, while optimizing shade tolerance of the photovoltaic device and increasing roof fill with regard to a roof on which the photovoltaic device is secured.

Integrated cell and circuit interconnection

A roofing system, includes: a roof deck; a first roofing shingle installed on the roof deck, where the first roofing shingle comprises a reveal portion and a head lap portion; a first step flap installed on the roof deck; and a first solar shingle installed on the roof deck, where the first solar shingle includes: a reveal portion, where the reveal portion includes a plurality of solar cells, a first side lap; a first side flap, and a second side flap, where the reveal portion of the first roofing shingle covers the first side flap of the first solar shingle, where a first portion of the first step flap covers the second side flap of the first solar shingle, where a second portion of the first step flap is under the first side lap of the first solar shingle.

Solar shingle and associated roofing system and method

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.
