Abstract

A buss bar strip for mounting to a solar panel to electrically connect to a series of electrical lines extending from solar cells. The buss bar strip can include a thin elongate flat flexible strip of insulative material having a longitudinal length. A predetermined pattern of elongate conductors can be longitudinally disposed on the insulative strip in at least two rows along the longitudinal length and electrically isolated from each other. Each conductor can have a predetermined position, length, and spacing from each other on the insulative strip for laterally electrically connecting to selected electrical lines from the solar cells at lateral electrical connection points located along the length of the conductor on exposed surfaces on the conductor.

Claims

1. A solar panel comprising:

a series of solar cells having a series of electrical lines extending therefrom at laterally spaced intervals; and

7. The solar panel of claim 6 in which the buss bar assembly includes a predetermined pattern of elongate conductors longitudinally disposed on the insulative strip along the longitudinal length and electrically isolated from each other, each of said conductors having a predetermined position, length and spacing from each other on the insulative strip.

8. The solar panel of claim 7 in which the insulative strip is formed of flexible polymeric material.

9. The solar panel of claim 1 in which the external device is an electrical connector having at least one female terminal that engages the at least one male circular connector.

10. A buss bar strip for mounting to a solar panel to electrically connect to a series of electrical lines extending from solar cells comprising:

at least one elongate conductor for laterally electrically connecting to selected said electrical lines from the solar cells at lateral electrical connection points located along the length of the at least one conductor on exposed surfaces on the at least one conductor, the at least one conductor including an electrical connection region for electrically connecting to an external device, at least one male circular connector being soldered to the electrical connection region.
