Abstract
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, the top surface 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.
Claims19
A method for making a photovoltaic roofing element comprising a flexible roofing substrate and one or more photovoltaic elements each disposed on the flexible roofing substrate and affixed thereto by an adhesive material, the method comprising:
- providing a flexible roofing substrate, the flexible roofing substrate having a top surface, the top surface having one or more receptor zones thereon, each of the one or more receptor zones having a different surfacing than the area of the top surface adjacent to it, each of the one or more receptor zones being adapted to receive the one or more photovoltaic elements, but having no photovoltaic elements disposed thereon;
- installing the flexible roofing substrate on a roof;
- and then,
- while the flexible roofing substrate is disposed on the roof, disposing the one or more photovoltaic elements on the top surface of the flexible roofing substrate, such that each of the one or more photovoltaic elements is disposed on one or more of the one or more receptor zones of flexible roofing substrate and affixed thereto by the adhesive material.
