This shows 2 arrays - one completed, and the other under construction. In both cases, the daily motion is about a horizontal axis, left to right. It is a tilt tip 2 axis tracker. The array with panels, is short of 3000 watts, and is oriented in the AM. The second, has no panels installed, but will have 4000 watts. It also has a stronger structure to resist wind loading. In addition, both axis of motion are not back drivable due to wind loading. Here is a 3-D    CAD model. I would not build another one of these because it is too costly.
