Abstract

A solar panel system includes a rail including a horizontal flange, a rib, and a channel. A clamp assembly includes a first member having a first side having a groove for receiving a portion of the rib and an anchor member for inserting into the channel. The clamp assembly further includes a second member slideably disposed on a second side of the first member and an actuator. When the actuator is actuated, the second member moves in a direction towards a bottom surface of a solar panel such that a top portion of the second member comes into contact with a bottom portion of the solar panel and electrically bonds with the solar panel, and an anchor member of the actuator comes into contact with an inside surface of the channel and electrically bonds with the rail.

First claim

What is claimed is:

1. A solar panel mounting system to mount a solar panel, the solar panel mounting system comprising:
a rail including:
an interior hollow cavity extending a longitudinal length, and
a channel separated from the interior hollow cavity, the channel extending along the longitudinal length such that the channel is slotted open to an outside of the rail; and

a clamp assembly for electrically bonding the solar panel to the rail upon installation of the solar panel, the clamp assembly including:
a first member having a first side opposite a second side,
a second member slideably disposed on the second side of the first member,
an actuator disposed to pass through the first member and the second member, and
an anchor member located at an end of the actuator and disposed adjacent to the first side of the first member, the anchor member being shaped to be accommodated within the channel of the rail during installation, whereby the actuator extends transversely to the longitudinal length of the rail,

wherein when the actuator is actuated,
the second member moves in a direction towards a bottom surface of the solar panel such that a top portion of the second member comes into contact with the bottom surface of the solar panel to electrically bond with the solar panel, and

the anchor member of the actuator comes into contact with an inside surface of the channel to electrically bond with the rail.

2. The solar panel mounting system of claim 1 , wherein the rail further includes a horizontal flange protruding from an upper surface of the rail along the longitudinal length, and the channel is disposed a distance below the horizontal flange.

3. The solar panel mounting system of claim 2 , wherein when the actuator is actuated, and the second member moves in the direction towards the bottom surface of the solar panel such that the top portion of the second member comes into contact with the bottom surface of the solar panel to electrically bond with the solar panel, a top surface of the solar panel comes into contact with a bottom portion of the horizontal flange.

4. The solar panel mounting system of claim 1 , wherein the first side of the first member includes a groove for receiving a portion of a rib of the rail.

5. The solar panel mounting system of claim 1 , wherein the anchor member is a first anchor member, and
wherein the first side of the first member includes a second anchor member for inserting into the channel of the rail.

6. The solar panel mounting system of claim 5 , wherein the first anchor member includes one or more protrusions for puncturing an anodized layer, galvanized layer, or a painted layer of the inside surface of the channel when the anchor member comes into contact with the inside surface of the channel to electrically bond with the rail.

7. A clamp assembly for use in a solar panel mounting system the clamp assembly comprising:
a first member having a first side opposite a second side, the first side including a first anchor member having a T-shape;
a second member having a sloped side to be slideably disposed on the second side of the first member;
an actuator disposed to pass through the first member and the second member; and
a second anchor member located at an end of the actuator and disposed adjacent to the first side of the first member, the second anchor member having the T-shape corresponding to the T-shape of the first anchor member,
wherein when the actuator is actuated, the second member moves in a direction towards the first member.

8. The the clamp assembly of claim 7 , wherein the second anchor member includes one or more protrusions for puncturing an anodized layer, galvanized layer, or a painted layer of a rail upon installation of the solar panel mounting system.

9. The the clamp assembly of claim 7 , wherein the top portion of the second member includes one or more protrusions for puncturing an anodized layer, galvanized layer, or a painted layer of the bottom surface of the solar panel when the top portion of the second member comes into contact with the bottom surface of the solar panel to electrically bond with the solar panel.

10. The the clamp assembly of claim 7 , wherein the first side of the first member further includes a groove for receiving a portion of a rib of the rail.

11. A solar panel mounting system to mount a first solar panel having a first thickness to a rail or a second solar panel having a second thickness different than the first thickness to the rail, the solar panel mounting system comprising:
a clamp assembly for electrically bonding the first solar panel having the first thickness to the rail upon installation of the first solar panel or electrically bonding the second solar panel having the second thickness different than the first thickness to the rail upon installation of the second solar panel, the clamp assembly including:
a first member having a first side opposite a second side,
a second member slideably disposed on the second side of the first member,
an actuator disposed with the first member and the second member, and
an anchor member having a T-shape fixed to an end of the actuator and disposed adjacent to the first side of the first member for inserting into the channel of the rail,

wherein, upon the installation of the first solar panel, and when the actuator is actuated:
the second member moves in a direction towards a bottom surface of the first solar panel such that a top portion of the second member comes into contact with the bottom surface of the first solar panel to electrically bond with the first solar panel having the first thickness, and
the anchor member of the actuator comes into contact with an inside surface of a channel of the rail to electrically bond with the rail, or

wherein, upon the installation of the second solar panel, and when the actuator is actuated:
the second member moves in a direction towards a bottom surface of the second solar panel such that the top portion of the second member comes into contact with the bottom surface of the second solar panel to electrically bond with the second solar panel having the second thickness different than the first thickness, and
the anchor member of the actuator comes into contact with the inside surface of the channel of the rail to electrically bond with the rail.

12. The solar panel mounting system of claim 11 , wherein, when the actuator is actuated, the second member is moveable between a down position and an up position, and wherein:
when in the down position the second member is positioned relative to the first member for electrically bonding with the first solar panel having the first thickness, and
when in the up position the second member is positioned relative to the first member for electrically bonding with the second solar panel having the second thickness different than the first thickness.

13. The solar panel mounting system of claim 12 , wherein the first thickness is 40 mm.

14. The solar panel mounting system of claim 12 , wherein the second thickness is 32 mm.

15. The solar panel mounting system of claim 12 , wherein the first side of the first member includes a groove for receiving a portion of a rib of the rail.

16. The solar panel mounting system of claim 12 , wherein the first side of the first member includes an anchor member for inserting into the channel of the rail.

17. The solar panel mounting system of claim 12 , wherein the anchor member of the actuator includes one or more protrusions for puncturing an anodized layer, galvanized layer, or a
