1. A photovoltaic roofing element comprising:
- a frame structure having an upward-facing surface and a downward-facing surface, the frame structure having an attachment zone and an exposure zone, with the exposure zone disposed toward the bottom end of the frame structure, and the attachment zone disposed toward the top end of the frame structure, the frame structure further having one or more raised sidewalls that at least partially define the area in which the one more photovoltaic elements are held; and
one or more photovoltaic elements held in the exposure zone of the frame structure, each photovoltaic element having a downward-facing surface,wherein the area in which the one or more photovoltaic elements are held has an upward-facing base surface, and wherein the frame structure further includes one or more raised structures protruding from the base surface, andwherein the one or more photovoltaic elements rest on the one or more raised structures, such that a gap remains between the downward-facing surface of the photovoltaic element and the upward-facing base surface of the frame structure, andwherein a first material adheres the photovoltaic element to the upward-facing base surface of the frame structure; and
wherein a second, different material seals the photovoltaic element to one or more of the one or more raised sidewalls of the frame structure.
