1. A system for controlling the position and orientation of a floating solar array, comprising:

(a) a floating solar array;

(b) a plurality of thrusters mounted to the floating solar array and extending below the floating solar array;

(c) a control system on the floating solar array for controlling operation of each of the plurality of thrusters, and

(d) a power cable connecting the floating solar array to an onshore grid.

2. The system of claim 1 , wherein the thrusters are retractable from a position below a water line to a position above the water line.

3. The system of claim 2 , wherein the floating solar array comprises a plurality of pontoons, and wherein the thrusters are mounted to the floating solar array to extend downwardly between the pontoons.

4. The system of claim 1 , wherein each of the thrusters is bi-directional such that the thruster can provide either forward or backward thrust in the direction that the thruster is pointing.

5. The system of claim 4 , wherein the floating solar array can be rotated without rotating the direction in which any thruster is pointing.

6. The system of claim 1 , wherein the plurality of thrusters comprise thrusters pointing in four directions, the four directions being at 45 degree angles to one another.

7. The system of claim 6 , wherein the plurality of thrusters comprise equal numbers of thrusters pointing in each of the four directions.

8. The system of claim 6 , wherein the plurality of thrusters comprise a greater number of thrusters pointing in a direction of prevailing wind or water currents.

9. The system of claim 1 , wherein at least one of the thrusters is rotatable around a vertical axis.

10. The system of claim 1 , further comprising:

(e) a power cable connector attaching the power cable to the floating solar array at a bottom central location on the floating solar array, such that the power cable connector permits rotation of the floating solar array without tangling of the power cable.

11. The system of claim 10 , further comprising:

an anchor positioned to hold a first mid-portion of the power cable below the water level; and

a buoy positioned to hold a second mid-portion of the power cable at the water level, and wherein the anchor is positioned between the power cable connector and buoy.

12. The system of claim 1 , wherein the plurality of thrusters are positioned both around the perimeter of the floating solar array and across the bottom of the floating solar array.

13. The system of claim 1 , further comprising:

(e) a submerged baffle extending downwardly below the floating solar array.

14. The system of claim 13 , wherein the submerged baffle is a wall shaped structure that is positioned perpendicular to prevailing wind or water currents.

15. The system of claim 1 , further comprising:

(e) a plurality of ballasted perimeter floats at the perimeter of the floating solar array.

16. A method of controlling the position and orientation of a floating solar array, comprising:

(a) providing a floating solar array having a plurality of thrusters thereon, the thrusters extending below the floating solar array;

(b) providing a control system on the floating solar array, wherein the control system activates the thrusters to:

rotate the floating solar array, and

push the floating solar array in a first direction.

17. The method of claim 16 , wherein each of the thrusters is bi-directional and the control system controls both the direction of operation and the power of the thrusters.

18. The method of claim 17 , wherein the plurality of thrusters comprise thrusters pointing in four directions, the four directions being at 45 degree angles to one another,

and wherein the control system activates the thrusters to rotate the floating solar array without rotating any of the plurality of thrusters.

19. The method of claim 16 , further comprising:

stowing the floating solar array in high winds by rotating the floating solar array into a direction perpendicular to the direction of the high winds.

20. The method of claim 16 , further comprising:

maintaining the floating solar array at a fixed position by:

sensing wind speed and direction,

activating the thrusters to push the floating solar array in a direction opposite to the wind, wherein the control system selects the power of the thrusters to correspond to the sensed wind speed.
