ROOFING PRODUCTS, PHOTOVOLTAIC ROOFING ELEMENTS AND SYSTEMS USING THEM

摘要

The present invention relates generally to roofing products. The present invention relates more particularly to roofing products for use with photovoltaic elements, and to photovoltaic systems that include one or more photovoltaic elements is joined to a roofing substrate. In one embodiment, a roofing product includes a flexible roofing substrate having a top surface having an exposure area, the exposure area having one or more receptor zones thereon, each receptor zone being adapted to receive one or more photovoltaic elements, each receptor zone having a different surfacing than the area of the top surface adjacent to it, wherein the one or more receptor zones and/or the exposure area have a height of about eight inches. In another embodiment, a photovoltaic roofing element includes a flexible roofing substrate having a top surface, the top surface having an exposure area having a height of about eight inches; and one or more photovoltaic elements disposed in the exposure area of the top surface of the flexible roofing substrate, each photovoltaic element having a height of about eight inches.
