Abstract

An article having an elongated plastic member characterized by a length to diameter ratio of at least 10, wherein the member has an exterior and a hollow interior. An electrical conductor having connectable terminations enclosed within the hollow interior, and a plurality of plastic appendages, spaced longitudinally along the exterior.

Claims

1. An article comprising an elongated plastic member characterized by a length to diameter ratio of at least 10, the member having an exterior and a hollow interior, an electrical conductor having connectable terminations enclosed within the hollow interior, and a plurality of plastic appendages, spaced longitudinally along the exterior, attached thereto and extending away therefrom, the plastic appendages being characterized by a length to diameter ratio of less than 25.

2. The article of claim 1 further comprising a wiring harness enclosed therewithin comprising pre-positioned spacers having wires and connectors attached thereto.

3. The article of claim 1 further comprising a seal that retards ingress of moisture, oxygen, and insects.

4. The article of claim 1 wherein the length to diameter ratio is at least 50.

5. A method comprising building a framework by connectingly engaging each of a plurality of horizontal plastic elongated members having a first and a second end, with a plastic appendage of a first vertical plastic elongated member with the first end of a horizontal elongated plastic member;

and connectingly engaging a plastic appendage of a second vertical plastic elongated member having appendages with the second end of the horizontal elongated plastic member;

wherein the plastic elongated members are characterized by a length to diameter length to diameter ratio of at least 10, and comprise an exterior and a hollow interior and an electrical conductor having connectable terminations enclosed within the hollow interior; and

wherein the plastic appendages are spaced longitudinally along the exterior of each the vertical elongated plastic member, attached thereto and extending away therefrom, the plastic appendages being characterized by a length to diameter ratio of less than 25.

6. The method of claim 5 wherein the vertical plastic elongated members further comprise a wiring harness enclosed therewithin comprising pre-positioned spacers having wires and connectors attached thereto.

7. The method of claim 5 wherein the vertical plastic elongated member further comprises a seal that retards ingress of moisture, oxygen, and insects.

8. The method of claim 5 wherein the length to diameter ratio of the vertical plastic elongated member is at least 50.

9. A photovoltaic array comprising a framework, and a plurality of photovoltaic modules disposed within the framework and connected thereto, the framework comprising a first plurality of vertical elongated plastic members characterized by an length to diameter ratio of at least 10, each the member having an exterior and a hollow interior, wherein at least a portion of the vertical elongated plastic members have an electrical conductor having connectable terminations enclosed within the hollow interior, and a second plurality of plastic appendages, spaced longitudinally along the exterior, attached thereto and extending away therefrom, the plastic appendages being characterized by an length to diameter ratio of less than 25;

a third plurality of horizontal elongated plastic members each having a first end and a second end, the horizontal elongated plastic members being characterized by an length to diameter ratio of at least 10, each the horizontal member having an exterior and a hollow interior, wherein each horizontal member is connected at a first end with a plastic appendage of a first vertical member, connected at a second end with a plastic appendage of a second vertical member;

wherein each the connectable termination is interconnected with either another the connectable termination or with a photovoltaic module to create an electrical circuit; and

, a an electrical output suitable for effecting a connection to an electrical load.

10. The photovoltaic array of claim 9 wherein the vertical plastic elongated members further comprise a wiring harness enclosed therewithin comprising pre-positioned spacers having wires and connectors attached thereto.

11. The photovoltaic array of claim 9 wherein the vertical plastic elongated member further comprises a seal that retards ingress of moisture, oxygen, and insects.

12. The photovoltaic array of claim 9 wherein the length to diameter ratio of the vertical plastic elongated member is at least 50.

13. The photovoltaic array of claim 9 wherein the photovoltaic modules comprise structural members consisting essentially of plastic.

14. The photovoltaic array of claim 9 wherein the photovoltaic modules comprise output connections within the panel frame to the frame element.
