Single Axis Array Mount - 1000 Watt

I would love to see 4-5 of these in someone's back yard. It is reasonable easy to fabricate. Some welding and machining. The machining part is on the short tube about which rotation occurs. And consists of machining in a raceway for a set of ball bearings, on either end. Yes, making a bearing. The SS ball bearings are available from McMasterr-Carr. The structure is robust enough to withstand wind loading.

The CAD views below have been revised to add mechanical stiffness to the linkage load path. In a windstorm, recently, the prototype vibrated / fluttered.

Click here for a CAD view of a single axis tracker with up to 1250 watts of panels. Takes a moment to load.

Click here for a CAD view of a 2 axis tracker with up to 1250 watts of panels. Takes a moment to load. It is unique in that it is a 2 axis tracker with the complexity of a single axis tracker. The second axis is manually adjusted.
