Abstract

Connectors, systems with connectors and processes with connectors are described. These include how connectors can actively hold external portions of two frames or other components together during transport and before final installation, as well as, how the connectors can be repositionable on the frame or other component so as to provide a mechanical connection in one position and not to provide a mechanical connection when moved into a second position. The connectors can also function to provide spacing or alignment or both between frames or other components grouped together using the connectors.

First claim

What is claimed is:

1. A connector system comprising:
a first photovoltaic module having a first frame rail;
a second photovoltaic module having a second frame rail; and
a first external connector, the first external connector comprising a first arm terminating in an anchor, a second arm connected to and extending away from the first arm, and a tail extending in a normal direction away from the first arm,
wherein the first external connector is coupled to the first photovoltaic module for transport of the first photovoltaic module with the second photovoltaic module and is coupled to the second photovoltaic module for transport of the second photovoltaic module with the first photovoltaic module,
wherein the first photovoltaic module is coupled to the second photovoltaic module in a stacked orientation,
wherein the first external connector restrains movement of the first photovoltaic module in at least one direction, and
wherein the first external connector restrains movement of the second photovoltaic module in at least one direction.

2. The connector system of claim 1 wherein the second arm terminates in a hook.

3. The connector system of claim 1 wherein the anchor comprises an external wall parallel to an external wall of the tail.

4. The connector system of claim 1 wherein the anchor and the tail define a space between them, the space surrounding a portion of the first frame rail.

5. The connector system of claim 1 wherein the tail terminates in a hook and comprises a plurality of compression bumps.

6. The connector system of claim 1 , wherein the first external connector comprises an extruded material.

7. The connector system of claim 6 , wherein the extruded material is a polymer.

8. The connector system of claim 1 wherein the wherein the first photovoltaic module is coupled to the second photovoltaic module in a vertical stacked orientation or a horizontal stacked orientation.

9. A frame and integrated external connector system comprising:
a plurality of integrated external connectors (IECs); and
at least two photovoltaic (PV) frames, each of the PV frames having an external rail on at least one side, the external rail having a cross-sectional shape with at least one perpendicular angle,
wherein the IECs comprise a first arm terminating in an anchor; a second arm; a hinge positioned between the first arm and the second arm; and a tail extending from the hinge, wherein the first arm, the second arm, and the tail comprise an extruded material.

10. The frame and integrated external connector system of claim 9 further comprising a plurality of straps encircling the at least two PV frames and wherein the second arm terminates in a flange.

11. The frame and integrated external connector system of claim 9 wherein the PV frames are each a polygon and are each connected to a PV panel having a plurality of PV cells.

12. The frame and integrated external connector system of claim 9 wherein the IECs are connected to the external rail of two PV frames and configured to slide when only connected to the rail of one PV frame.

13. An extruded connector comprising:
a pair of arms, a first arm of the pair extending in a first direction, a second arm of the pair extending in a second direction, the pair coupled to a body portion, the body portion including a third arm, the third arm extending from the body portion,
the first arm comprising a deformable section, the deformable section extending behind a first exposed surface of the first arm, the second arm terminating in a hook the hook comprising one or more hollows,
wherein the hook, pair of arms, body portion, and third arm comprise an extruded material.

14. The connector of claim 13 wherein the hook, pair of arms, body portion, and third arm comprise a flexible polymer.

15. The connector of claim 13 wherein the hook comprises a bulbous end.

16. The connector of claim 13 wherein the body portion comprises an elongated planar section connecting the pair of arms and the hook.

17. The connector of claim 13 wherein the pair of arms form a flange coupled to the body portion.

18. A connector system comprising:
a first photovoltaic module having a first frame rail;
a second photovoltaic module having a second frame rail; and
a first external connector, the first external connector comprising a first arm terminating in an anchor, a second arm connected to and extending away from the first arm, and a tail extending in a normal direction away from the first arm,
wherein the first external connector is coupled to the first photovoltaic module and is coupled to the second photovoltaic module,
wherein the first external connector restrains movement of the first photovoltaic module in opposing lateral directions,
wherein the first external connector restrains movement of the second photovoltaic module in at least one direction, and
wherein the anchor comprises a hollow.

19. A connector system comprising:
a first photovoltaic module having a first frame rail;
a second photovoltaic module having a second frame rail; and
a first external connector, the first external connector comprising a first arm terminating in an anchor, a second arm connected to and extending away from the first arm, and a tail extending in a normal direction away from the first arm,
wherein the first external connector is coupled to the first photovoltaic module and is coupled to the second photovoltaic module,
wherein the first external connector restrains movement of the first photovoltaic module in opposing lateral directions,
wherein the first external connector restrains movement of the second photovoltaic module in at least one direction, and
wherein the first arm and the second arm are connected at a hinge.

20. A polymeric PV module transport connector comprising:
a pair of arms, a first arm of the pair extending in a first direction, a second arm of the pair extending in a second direction, the pair coupled to a body portion, the body portion including a third arm, the third arm extending from the body portion,
