Claims:

1. A solar tracker, comprising:

a first set of one or more solar modules mounted on a first rail;

a second set of one or more solar modules mounted on a second rail;

the first and second rails pivotably connected to a first outer rail at a first end of the first and second rails and pivotably connected to a second outer rail at a second end of the first and second rails opposite of the first end wherein the first and second outer rails control the azimuth of the solar modules; and

a center rail pivotably connected to the center of each of the set of one or more solar modules and being substantially perpendicular to the rail and second rails wherein the center rail controls the altitude of the solar modules.

2. A solar tracker, comprising;

a first azimuth rail and a second azimuth rail spaced apart for each other;

a first altitude rail and a second altitude rail spaced apart for each other;

an azimuth controller coupled to the first azimuth rail and the second azimuth rail that control the azimuth angle of a mount by moving the first azimuth rail and the second azimuth rail;

a tilt controller coupled to the first altitude rail and the second altitude rail that control the tilt angle of the mount by moving the first altitude rail and the second altitude rail; and a controller that controls the azimuth controller and the tilt controller.

3. The solar tracker of claim 2 further comprising a set of arms that couple the first azimuth rail and the second azimuth rail to the azimuth controller.

4. The solar tracker of claim 3, wherein the azimuth controller further comprises a first azimuth actuator and a second azimuth actuator that control the movement of the first azimuth rail and the second azimuth rail.

5. The solar tracker of claim 2 further comprising a set of arms that couple the first altitude rail and the second altitude rail to the tilt controller.

6. The solar tracker of claim 5 further comprises a swivel mount that converts the movement of the first attitude rail and the second altitude rail into a tilting movement of the solar module.

7. The solar tracker of claim 2, wherein the tilt controller further comprises an altitude actuator that controls the movement of the first altitude rail and the second altitude rail.

8. The solar tracker of claim 2, wherein the controller automatically calibrates the azimuth controller and the tilt controller during start-up.

9. The solar tracker of claim 2, wherein the controller automatically determines a horizon during start-up.

10. A method for moving a solar module to track the sun, the method comprising: providing a solar tracker that has a first azimuth rail and a second azimuth rail spaced apart for each other, a first altitude rail and a second altitude rail spaced apart for each other, an azimuth eontroller coupled to the first azimuth rail and the second azimuth rail that control the azimuth angle of a mount by moving the first azimuth rail and the second azimuth rail, a tilt controller coupled to the first altitude rail and the second altitude rail that control the tilt angle of the mount by moving the first altitude rail and the second altitude rail, and a controller that controls the azimuth controller and the tilt controller;

controlling the azimuth angle of the solar module using the azimuth controller and the first and second azimuth rails; and

controlling the tilt of the solar module using the tilt controller and the first and second altitude rails.

1 1. The method claim 10 further comprising automatically calibrating the azimuth controller and the tilt controller during start-up.

12. The method of claim 10 further comprising automatically determining a horizon during start-up.

13. A solar module installation, comprising:

at least one solar module mounted on a control module;

at least one solar module mounted on an extension module wherein the control module controls the movement of the solar module mounted in the control module and the extension module; and

the control module further comprising a first azimuth rail and a second azimuth rail spaced apart for each other; a first altitude rail and a second altitude rail spaced apart for each other; an azimuth controller coupled to the first azimuth rail and the second azimuth rail that control the azimuth angle of the solar module mounted on the control module by moving the first azimuth rati and the second azimuth rail; a tilt controller coupled to the first altitude rail and the second altitude rail that control the tilt angle of the solar module mounted on the

control module by moving the first altitude rail and the second altitude rail; and a controller that controls the azimuth controller and the tilt controller.
