NOVELTY - The system (100) has a top piece that includes a base piece attachment feature. A covering flange extends outwardly from a side of the top piece. A vertically extending portion extends upwardly from the base piece attachment feature and the flange. A photovoltaic element (120) is arranged on a roof adjacent the base piece. A top edge (122), a bottom edge (124) and side edges (126) of the photovoltaic element are fixed on a horizontally-extending flange of the base piece of a two-part tee element (141). The covering flange of the top piece overlaps a top surface of the photovoltaic element.    USE - Photovoltaic roofing system for use on a roof deck.    ADVANTAGE - The two-part tee or framing element can allow for easy replacement of damaged parts and changes in shape and color as desired to adapt the visual aspect of the array so as to avoid damage to framing pieces while installation is in progress and avoid workers tripping over the framing pieces and potentially damaging the frame pieces or the photovoltaic element. The system realizes solar reflective aspect to enable a part to have less heat buildup on a roof and reduced tendency for heat distortion or other dimensional changes in use, and can accommodate the fasteners and allow hard nailing while minimizing issues of buckling due to thermal expansion and contraction or movement of the roof as the flexible material can dissipate or redirect the mechanical stresses when the side flanges of the base piece are made from a flexible material.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following:    (1) a method for installing a photovoltaic roofing system on a roof    (2) a kit for installation of a photovoltaic roofing system.
