NOVELTY - The module (100) has a base sheet comprising a rigid polymer portion and a flexible polymer portion, where the flexible polymer portion is positioned in a support flap area of the module and penetrated by mechanical fasteners to provide mechanical support to the sheet with respect to a building structure. Photovoltaic cells (102) are attached to the rigid polymer portion of the sheet. The flexible polymer portion comprises multiple separate patches separated from each other by potions of the sheet, and hole indicators on a front surface of the flexible polymer portion.    USE - Integrable photovoltaic module for providing integration into structures in various parts of buildings e.g. rooftops, skylights and facades. Can also be used in roofing materials e.g. asphalt shingles.    ADVANTAGE - The module utilizes a back sealing sheet with a metallized layer so as to improve water permeability characteristics of a sealing sheet. The module utilizes a support sheet to be attached to a back sheet without separate support edge or other separate supporting elements. The photovoltaic cells are electrically interconnected in series so as to increase voltage output of the module. The module utilizes a socket and a pin with protrusions extending toward each other to minimize electrical contact resistance by increasing a contact area of the socket and the pin. The module utilizes the rigid polymer portion and the flexible polymer portion in a support flap area, which provides adequate rigidity and is easily penetrated with the mechanical fasteners during installation without damage to the surrounding area.    DETAILED DESCRIPTION - The mechanical fasteners are nails. An INDEPENDENT CLAIM is also included for a method for installing a building integrable photovoltaic module onto a building structure.
