Abstract

This disclosure is directed to apparatuses, systems, and methods associated with the stowing, deploying, and deployment of a solar cell array. With reference to some exemplary embodiments this disclosure teaches apparatuses, systems, and methods directed to a solar cell array system that is a relatively lightweight, compact, and self-contained structure that securely stores, protects, and deploys the solar array. With reference to some exemplary embodiments this disclosure teaches apparatuses, systems, and methods for deploying a solar cell array that is held in the deployed configuration by self-contained compressive force and tensile force members such that no loads are carried through the solar cell panels.

First claim

What is claimed is:

1. A method for deploying a solar cell array, comprising:
positioning a solar cell array system to be deployed, having a first support releasably attached to a second support;
detaching the first support of the solar cell array system from the second support of the solar cell array system;
extending at least one compressive force member connected to both the first and second supports of the solar cell array system, such that the first support is pushed away from the second support, the solar cell array system comprising a first restraint rail and a second restraint rail;
pulling from the second support with the first support, a solar cell array to an end point position, the solar cell array releasably supported by the first restraint rail and the second restraint rail, the solar cell array comprising a first load bearing edge attached at a first end to the first support and attached at a second end to the second support, and a second load bearing edge attached at a first end to the first support and attached at a second end to the second support, wherein the first load bearing edge and the second load bearing edge each comprise a plurality of hingedly attached end flanges;
supporting at least one solar panel from a first end attached to the first load bearing edge and from a second end attached to the second load bearing edge; and,
extending the first support a distance from the second support to define an end point position of the deployed solar cell array.

2. The method of claim 1 , further comprising extending the compressive force member until a sufficient tensile force is created in the first load bearing edge and second load bearing edge to maintain the first support at the end point position.

3. The method of claim 1 , further comprising extending at least one tensile force member connected to both the first and second supports.

4. The method of claim 3 , further comprising extending the compressive force member until a sufficient tensile force is created in the tensile force member to maintain the first support at the end point position.

5. The method of claim 1 , further comprising providing tension to at least one of the first and second load bearing edges utilizing at least one panel tensioner.

6. The method of claim 5 , further comprising launching a vehicle that includes a solar cell array assembly.
