Abstract

A field-deployable photovoltaic power system having solar modules and associated electronics that are stored in a standard shipping container and are manually deployed to form an array above the shipping container, with the shipping container providing the structural base for the photovoltaic array disposed thereabove.

First claim

What is claimed is:

1 . A field-deployable self-contained photovoltaic power system, comprising:
a shipping container having a bottom portion, a roof portion, and wall portions separating the bottom portion and the roof portion; a plurality of mounting structures, each mounting structure comprising at least one space frame, configured to support at least one photovoltaic module independent of the shipping container, and pivotally connected to a bottom exterior surface of the shipping container, and movable between a lowered position and a raised position; and a plurality of photovoltaic modules, each photovoltaic module being attachable onto one of the mounting structures, wherein the plurality of mounting structures in the lowered position are configured to receive and attach to the plurality of photovoltaic modules, and wherein the plurality of mounting structures in the raised position, with the plurality of photovoltaic modules attached thereto, are disposed to form a photovoltaic array.

2 . The system of claim 1 , wherein the plurality of mounting structures comprises mounting structures on opposite sides of the shipping container, such that the plurality of mounting structures in the raised position, with the plurality of photovoltaic modules attached thereto, supports the photovoltaic array which extends over the top of the shipping container.

3 . The system of claim 2 , wherein the photovoltaic module array includes a center row of photovoltaic modules suspended by both of the mounting structures on opposites sides thereof.

4 . The system of claim 1 , wherein each mounting structure comprises:
a first frame member having a bottom end rotatably connected to a bottom edge of the shipping container; a second frame member connected to a top end of the first member; and a third frame member connected at opposite ends to each of the first and second frame members, wherein, with the mounting structure in the raised position, the third frame member supports a free end of the second frame member.

5 . The system of claim 4 , wherein, with the mounting structure in the raised position, the first frame member is rotated to a vertical position, is attached onto a top edge of the shipping container, and is in the raised position above the shipping container.

6 . The system of claim 4 , wherein, with the mounting structure in the raised position, the second frame member is rotated to a generally horizontal position above the shipping container.

7 . The system of claim 4 , wherein the third frame member is connected at 45 degree angles to each of the first and second frame members.

8 . The system of claim 1 , further comprising guide wires extending outwardly away from at least one of the four corners of the photovoltaic array.

9 . The system of claim 4 , further comprising mounting rails spanning across each of the second frame members in the plurality of mounting structures disposed parallel to one another.

10 . The system of claim 9 , wherein the mounting rails comprise an outer mounting rail, a first lateral mounting rail, a second lateral mounting rail, and an inner mounting rail.

11 . The system of claim 10 , wherein an upper row and a lower row of photovoltaic modules are pivot connected onto the first lateral mounting rail with bottom edges of the upper row of photovoltaic modules being connected to the first lateral mounting rail and top edges of the lower photovoltaic modules being connected to the first lateral mounting rail.

12 . The system of claim 1 , further comprising:
at least one inverter configured to convert energy generated by the photovoltaic array from direct current to alternating current; and at least one battery in the shipping container, the battery being electrically connected to store energy generated by the photovoltaic array.

13 . A method of deploying a self-contained photovoltaic power system, comprising:
withdrawing components for a plurality of mounting structures and a plurality photovoltaic modules from within a shipping container; assembling the plurality of mounting structures on opposite sides of the shipping container, each mounting structures pivotally connected to a bottom exterior surface of the shipping container, and movable between a lowered position and a raised position; on the opposite sides of the shipping container, connecting the plurality of mounting structures to each other with a plurality of mounting rails; with the plurality of mounting structures in a lowered position on the ground, attaching a portion of the plurality of photovoltaic modules to the mounting rails; manually raising each plurality of mounting structures on opposite sides of the shipping container to the raised position, disposing the attached portion of the plurality of photovoltaic modules above the shipping container; and mounting a further portion of the plurality of photovoltaic modules between the mounting structures in the raised position, thereby forming a photovoltaic array.

14 . The system of claim 13 , wherein manually raising each plurality of mounting structures is performed with a hoist and cable manually operable by an installer.

15 . The system of claim 13 , wherein the shipping container acts as a counter-balance and remains in position as the mounting structures are raised on opposite sides thereof.

16 . The system of claim 13 , wherein mounting a further portion of the plurality of photovoltaic modules between the mounting structures in the raised position is performed by an installer positioned on top of the shipping container.

17 . The system of claim 1 , wherein a portion of the plurality of photovoltaic modules are attached to the mounting rails on a side of the shipping container in two rows by an installer on the ground.

18 . A microgrid network, comprising:
one or more field-deployable self-contained photovoltaic power systems, each comprising:
a shipping container;
two or more sets of mounting structures, each mounting structure being pivotally connected to a lower exterior edge of the shipping container, each mounting structure configured to rotate between a lowered position and a raised position, with at least one set of mounting structures on either longitudinal side of the shipping container; and
a set of photovoltaic modules, where each photovoltaic module is configured to couple onto one set of the mounting structures when the mounting structures are in the lowered position, and where each photovoltaic module is configured to couple with one set of mounting structures on either side of the photovoltaic module when the mounting structures are in the raised position; and
wherein each of the one or more of field-deployable self-contained photovoltaic power systems is electrically connected to a local off-grid power load.

19 . The microgrid network of claim 18 , wherein one or more inverters are electrically connected to the set of photovoltaic modules with the one or more inverters located within the shipping container for each photovoltaic power system, on each photovoltaic module of the set photovoltaic modules, or a combination thereof.

20 . The microgrid network of claim 18 , wherein the one or more field-deployable self-contained photovoltaic power systems are electrically connected to each other and are electrically connected to the local off-grid power load as a single power source.
