Photovoltaic sheathing element with one or more tabs

1. An assembly comprising:

a photovoltaic sheathing element capable of being affixed on a building structure, the photovoltaic sheathing element including at least:

a body portion having:

a top side,

a bottom side opposing the top side,

a first side edge,

a second side edge opposing the first side edge, the first side edge and the second side edge extending between and connecting the top side and the bottom side, and

a receiving zone disposed on an underside of the body portion;

a photovoltaic cell assembly, the photovoltaic cell assembly having one or more portions attached to the body portion; and

at least a first connector assembly located in the first side edge and a second connector assembly disposed in the second side edge of the photovoltaic sheathing element and capable of directly or indirectly electrically connecting the photovoltaic cell assembly to one or more horizontally adjoining devices;

wherein the body portion includes two or more top peripheral tabs that are a localized extensions of the top side of the body portion and the two or more top peripheral tabs are each capable of fitting under a bottom edge of one or more vertically adjoining devices;

wherein the receiving zone includes two or more distinct grooves formed within a back surface of the underside of the body portion for receiving the two or more top peripheral tabs of the one or more vertically adjoining devices such that each of the two or more grooves receives a single one of the two or more top peripheral tabs.

2. The assembly according to claim 1 , wherein the combination of the two or more top peripheral tabs and the two or more distinct grooves of the receiving zone provide a positive horizontal positioning zone for the photovoltaic sheathing element to the one or more vertically adjoining devices.

3. The assembly according to claim 1 , wherein the two or more top peripheral tabs have a length defined by L tp =L tpn +L tpt where L tp =(W bp −(2*W exp )−n+C1*(L bp /W exp ))+(C2*T o *(1/roof pitch)).

4. The assembly according to claim 1 , wherein the two or more top peripheral tabs each include one or more fluid directing features that channel a fluid away from a perimeter edge of the photovoltaic sheathing element.

5. The assembly according to claim 1 , wherein the two or more top peripheral tabs are disposed on the photovoltaic sheathing element in an area that is laterally adjacent to a predetermined fixation area of the one or more vertically adjoining devices.

6. The assembly according to claim 1 , wherein the two or more top peripheral tabs aid in vertically positioning the photovoltaic sheathing element relative to adjacent devices and the two or more top peripheral tabs have a thickness that is small enough so that the two or more top peripheral tabs are capable of fitting under the one or more vertically adjoining devices.

7. The assembly according to claim 1 , wherein at least one of the two or more top peripheral tabs is in a position to so that the at least one top peripheral tab fits under at least two vertically adjoining devices.

8. The assembly according to claim 7 , wherein the at least one top peripheral tab fits in an area where an electrical connector is present.

9. The assembly according to claim 4 , wherein the two or more top peripheral tabs have a planar surface and each of the one or more fluid directing features is a projection disposed on the planar surface of the two or more top peripheral tabs.

10. The assembly according to claim 7 , wherein the at least one of the two or more top peripheral tabs fits in an area where the at least two vertically adjoining devices meet.

11. The assembly according to claim 4 , wherein the two or more top peripheral tabs have a planar surface and each of the one or more fluid directing features is a valley disposed on the planar surface of the two or more top peripheral tabs.

12. The assembly according to claim 9 , wherein the one or more fluid directing features are a compressible material and the compressible material is selected from a gasket material, an elastomer or caulk.
