NOVELTY - The array of assembly comprises a photovoltaic building sheathing element (10). The photovoltaic building sheathing element is affixed on a building structure, and includes a pre-bend. The building structure comprises a photovoltaic cell assembly, a body portion that is attached to portions of the photovoltaic cell assembly, and first and second connector assemblies capable of directly or indirectly electrically connecting the photovoltaic cell assembly to horizontally adjoining devices. The body portion includes geometric features.    USE - The array of assembly including a photovoltaic building sheathing element is useful in photovoltaic devices such as solar devices installed in roofing shingles or exterior wall- coverings.    ADVANTAGE - The array of assembly including the photovoltaic building sheathing element enhances lifespan and resistance against moisture damage of the photovoltaic devices, and reduces cost of installation of the photovoltaic devices.    DETAILED DESCRIPTION - The array of assembly comprises a photovoltaic building sheathing element (10). The photovoltaic building sheathing element is affixed on a building structure, and includes a pre-bend. The building structure comprises a photovoltaic cell assembly, a body portion that is attached to portions of the photovoltaic cell assembly, and first and second connector assemblies capable of directly or indirectly electrically connecting the photovoltaic cell assembly to horizontally adjoining devices. The body portion includes geometric features that are adapted to engage a vertically adjoining device before installation. The pre-bend includes a vertical bend distance of 3-35 mm as measured under a fixation area (800) and normal to the building structure. The geometric feature comprises extended ledge ribs disposed on an underside of the photovoltaic building sheathing element, and top peripheral tabs (600). The extended ledge ribs are capable of engaging a top peripheral edge of the vertically adjoining device. The tabs include an upwardly extending portion (610). The upwardly extending portion: begins greater than or equal to 10mm from a distal end of the top peripheral tabs; has an angle of 5-8 degrees relative to a plane defined by a mounting surface of the building structure; extends from an upper surface of the top peripheral tabs; and is capable of being flattened out with the exertion of a force of greater than or equal to 7 Newtons applied normal to a distal end of the upwardly extending portion. The extended ledge rib is capable of being flattened out with the exertion of the force of greater than or equal to 7 Newtons applied normal to a distal end of the extended ledge rib. The first and second connector assemblies are disposed on opposite sides of the photovoltaic building sheathing element.
