Abstract

An electrical power transmission system where there are solar cells attached to a plurality of transmission poles. The cells are in panels wrapped around the poles to reduce windage loading and visual impact.

Claims

1. An arrangement where there are a plurality of electric power supply poles supporting sequentially an electric power transmitting cable or cables and take offs for users from such cables, each of a plurality of the poles having a lower end embedded in the ground and being supported thereby to extend at least approximately vertically therefrom, the electric power transmitting cables being supported at or near a top of each respective pole, and a panel comprising or including solar cells being solar to electric transducers distributed across said panel, being attached one to each of a plurality of the poles and being at least to some extent in each case wrapping around its respective vertically aligned pole, and for each panel an electronic circuit electrically connected to the cells and providing translating of electrical power from said cells to a phase and voltage matching input into the said electrical distribution network.

2. An arrangement as in claim 1 where the electric power transmitting cables are supported by cross trees secured to each respective pole.

3. An arrangement as in claim 1 further characterized in that at least some of the solar cells are in the form of a panel which is at least to some extent wrapped around a supporting pole and orientated so that at least some of the solar cells will be directly illuminated by the sun during at least most of a day.

4. An arrangement as in claim 1 in which at least some of the solar cells are positioned to be in a vertically aligned group facing in a common polar direction and where the cells in the group are electrically connected in series.

5. An arrangement as in claim 4 where there are a plurality of such vertically aligned groups positioned adjacent one to the other and aligned to be for each group in a different pointing polar direction so that the sun will sequentially illuminate each of the groups predominantly through a day.

6. An arrangement as in claim 1 where the panel of solar cells is supported so as to have a cooling air space between the cells and the pole.

7. An arrangement as in claim 4 where the spread of polar direction of the groups in a panel are within the range of from 90 degrees to 150 degrees.

8. An arrangement as in claim 1 further characterised in that each solar panel is set off to leave between an outer surface of the pole and an inner side of the panel or at least an inner surface portion of the panel a channel or channels so as to facilitate conduction of air therethrough and thereby assist in effecting convection cooling of a panel.

9. An arrangement as in claim 1 further characterised in that each panel is positioned only at an upper part of the pole.

10. An arrangement as in claim 1 further characterised in that the solar cells are connected to either a 240 volt or 110 volt alternating current supply by a phase locked inverter.

11. An electrical power distribution installation with sequentially aligned power poles supporting electrical distribution wires and having connected thereto electrical feeds including a group of ground supported power poles positioned and spaced apart alignment each supporting on a cross arm or arms, electrical wires and extending from pole to pole to provide a common electrical grid providing an electrical power distribution network, and at least one of the poles having a panel of solar cells attached to and being supported by the pole and positioned to have an upper extent of active solar cells being below any cross arm and having any lowest portion substantially above a ground level, being secured to allow a surface of a respected pole and extending at least partially around the pole so that it is orientated in an appropriate better sun receiving position around the pole.

13. An electrical power distribution installation as in claim 11 further characterised in that the panel of solar electrical cells is in sheet form and shaped with a curve about a vertical axis with a pole portion aligned and positioned within a concave shape provided by such curve.

12. An electrical power distribution installation including a plurality of ground support power poles positioned and spaced apart alignment each supporting on a cross arm or arms, electrical wires which also extend from pole to pole to provide a common electrical grid providing an electrical power distribution network using a first common electrical power source derived from a transformer provided by electrical power at a higher voltage, and at least one of the poles having a panel of solar cells attached to and being supported by the pole and positioned to have an upper extent of active solar cells being below any cross arm and having any lowest portion substantially above a ground level, to an outer surface thereto being positioned so as to only extend approximately coincidentally across a face or faces that is or are aligned to receive at least substantial sunlight directly.

14. An electrical power distribution installation as in claim 12 further characterised in that the panel of solar electrical cells is in sheet form and shaped with a curve about a vertical axis with a pole portion aligned and positioned within a concave shape provided by such curve.
