US Patent:

45741603, Mar 4, 1986

Filed:

Sep 28, 1984

Appl. No.:

6/656175

Inventors:

Ronald C. Cull - Milan OH
Robert A. Hartman - Chagrin Falls OH
Paul E. Koch - Chagrin Falls OH

Assignee:

The Standard Oil Company - Cleveland OH

International Classification:

H01L 2502

US Classification:

136245

Abstract:

A photovoltaic array module incorporating a plurality of photovoltaic cell strips (11). Each cell strip (11) incorporates an electrically conductive substrate layer (22), a semiconductor body (23) deposited on the substrate layer (22), and a transparent electrically conductive layer (24) deposited on the semiconductor body (23). Electrically conductive filaments (20) are alternately connected to contact points (31) on the electrically conductive substrate layer (22) of one cell strip (11) and to contact points (32) on the transparent electrically conductive layer (24) of another cell strip (11). A first busbar (12) and a second busbar (13) are connected to the end cell strips (11) of the array to collect the electrical energy generated thereby.

International Classification:

H01L 2502

US Classification:

136251

Abstract:

A semirigid support member is provided for deploying flexible photovoltaic modules in a manner that imparts a degree of rigidity and permanence to the deployment. The semirigid support members provide lightweight economical means for lending structural support to flexible photovoltaic modules. The support members may be interconnected and additionally connected to a permanent base foundation.

International Classification:

G01R 3108

US Classification:

324501

Abstract:

The present invention discloses a method of detecting and locating current imbalances such as ground faults in multiwire systems using the Faraday effect. As an example, for 2-wire or 3-wire (1 ground wire) electrical systems, light is transmitted along an optical path which is exposed to magnetic fields produced by currents flowing in the hot and neutral wires. The rotations produced by these two magnetic fields cancel each other, therefore light on the optical path does not read the effect of either. However, when a ground fault occurs, the optical path is exposed to a net Faraday effect rotation due to the current imbalance thereby exposing the ground fault.
