a conductor housing located on the top surface, wherein the conductor housing further comprises a wire cradle and a cap; and

a channel extending from the top surface to the bottom surface,

wherein the channel is configured to receive a flowable sealant, and

wherein the channel connects to an inner surface of the conductor housing.

2. A cord plate according to claim 1 , further comprising a side surface connecting the top surface to the bottom surface.

3. The cord plate according to claim 2 , wherein the side surface is concave.

4. A cord plate according to claim 1 , wherein the cap contains a vent hole.

5. A cord plate according to claim 1 , wherein the cap is attached to the wire cradle by a hinge.

6. A cord plate according to claim 1 , wherein the cap is detachable from the wire cradle.

7. A cord plate according to claim 1 , wherein the cap is attached to the wire cradle by a clip.

8. A cord plate according to claim 1 , wherein the conductor housing further comprises:

a seal on the inner surface,

wherein the seal extends around the inner surface.

9. A cord plate according to claim 1 , wherein the conductor retainer is integrated into the top surface of the cord plate.

10. A cord plate according to claim 1 , wherein the conductor retainer is fastened to the top surface of the cord plate.

11. A cord plate according to claim 1 , wherein the conductor retainer is a wire clip.

12. A cord plate according to claim 1 , wherein the conductor housing is at least 5 mm in length.

13. A photovoltaic module, comprising:

a cord plate, comprising:

a top surface;

a bottom surface;

a conductor retainer located on the top surface;

a conductor housing located on the top surface, wherein the conductor housing further comprises a wire cradle and a cap; and

a channel extending from the top surface to the bottom surface,

wherein the channel is configured to receive a flowable sealant, and

wherein the channel connects to an inner surface of the conductor housing;

a first conductor, comprising:

a first end;

a second end; and

a central region located between the first end and the second end;

a cover plate, comprising:

a first surface; and

a second conductor coupled to the first surface

wherein the bottom surface of the cord plate is mated to the first surface of the cover plate,

wherein the first end of the first conductor is inserted into the conductor housing,

wherein the first end of the first conductor is connected to the second conductor,

wherein the central region of the first conductor is secured by the conductor retainer,

wherein a flowable sealant is introduced into the channel.

14. A photovoltaic module according to claim 13 , further comprising:

a side surface connecting the top surface to the bottom surface,

wherein the side surface is concave.

15. A photovoltaic module according to claim 13 , wherein the cap contains a vent hole.

16. A photovoltaic module according to claim 13 , wherein the cap is attached to the wire cradle by a hinge.

17. A photovoltaic module according to claim 13 , wherein the conductor housing further comprises:

a seal on the inner surface,

wherein the seal extends around the inner surface.

18. A method for attaching a cord plate to a photovoltaic module, comprising:

providing a cord plate, comprising:

a top surface;

a bottom surface;

a conductor retainer located on the top surface;

a conductor housing located on the top surface, wherein the conductor housing further comprises a wire cradle and a cap; and

a channel extending from the top surface to the bottom surface;

wherein the channel is configured to receive a flowable sealant, and

wherein the channel connects to an inner surface of the conductor housing;

providing a first conductor, comprising:

a first end;

a second end; and

a central region located between the first end and the second end;

providing a cover plate, comprising:

a first surface; and

a second conductor coupled to the first surface;

positioning the bottom surface of the cord plate against the first surface of the cover plate;

inserting the first end of the first conductor into the conductor housing;

connecting the first end of the first conductor to the second conductor;

securing the central region of the first conductor with the conductor retainer;

introducing a flowable sealant into the channel.

19. A method according to claim 18 , wherein the cord plate further comprises:

a side surface connecting the top surface to the bottom surface,

wherein the side surface is concave.

20. A method according to claim 18 , wherein the cap contains a vent hole.

21. A method according to claim 18 , wherein the cap is attached to the wire cradle by a hinge.

22. A method according to claim 18 , wherein the cap is attached to the wire cradle by a clip.

23. A method according to claim 18 , wherein the conductor housing further comprises:

a seal on the inner surface, wherein the seal extends around the inner surface.

24. A method for generating electricity, the method comprising:

illuminating a photovoltaic module with light to generate a photocurrent; and

collecting the photocurrent, wherein the photovoltaic module comprises a cord plate, and wherein the cord plate comprises:

a top surface;

a bottom surface;

a conductor retainer located on the top surface;

a conductor housing located on the top surface, wherein the conductor housing further comprises a wire cradle and a cap; and

a channel extending from the top surface to the bottom surface,

wherein the channel is configured to receive a flowable sealant, and

wherein the channel connects to an inner surface of the conductor housing.

25. The method of claim 24 , wherein the cord plate further comprises a side surface connecting the top surface to the bottom surface, wherein the side surface is concave.

26. A method according to claim 24 , wherein the cap contains a vent hole.

27. The method of claim 24 , wherein the cap is attached to the wire cradle by a hinge.
