NOVELTY - The system has horizontally-arranged primary photovoltaic roofing elements that are provided on roof deck. Flashing element has top end and bottom end that overlaps top end of primary photovoltaic roofing elements. Horizontally-arranged secondary photovoltaic roofing elements positioned on roof deck upwards from flashing elements. Each secondary photovoltaic roofing element has top end and bottom end that overlaps the top end of flashing elements. The secondary photovoltaic roofing elements does not overlap the bottom end of any of the flashing elements.    USE - Photovoltaic roofing system for use on roof deck.    ADVANTAGE - The photovoltaic roofing system can provide for ease of access to wiring and fasteners used in the installation of the photovoltaic roofing system. The components of the photovoltaic roofing system are allowed to be easily upgraded, repaired or replaced. The primary photovoltaic roofing elements can be removed from the roof without having to detach, lift, or move the secondary photovoltaic roofing elements. The wiring can be accessed for repair by moving or detaching the flashing element, without having to move or detach any photovoltaic roofing elements. The use of the flashing overlaps the fastener so as to prevent a leak occurred by penetrating the photovoltaic roofing element and the roof deck by the fastener. The fastener can be undone to allow the bottom end of the flashing element to be lifted. The material of the flashing element is polycarbonate, aluminum, or rigid polypropylene, so that efficient support is provided to the overall assembly and protection for any wiring or components underlying the flashing elements is enabled. The hinge can be used to allow the flashing element to be lifted. The portion of the flashing element is flexible enough such that bottom end of flashing element can be lifted away from the surface of the primary photovoltaic element without undergoing plastic deformation. Horizontally-adjacent photovoltaic roofing elements overlap or interlock with one another to close the roof from moisture. Horizontally-adjacent flashing elements overlap or interlock with one another to close the roof from moisture.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) a method for accessing top end of primary photovoltaic element in photovoltaic roofing system; and    (2) a method for accessing wiring in photovoltaic roofing system.    DESCRIPTION OF DRAWING(S) - The drawing shows a partial perspective view of a photovoltaic roofing system.
