Default Accurate tracking!

I could not use the sensor pod shadow to gauge how well the tracker was working this morning,
it wasn't manufactured symmetrically, it's off-set up and to the right of it's base.

So I installed an 11" threaded 1/4" rod in the center, so I could see the shadow it cast.



As you can see, it's shadow is about 0.25" long. So far, that's as long as it ever gets.
The mount seems to be moving about every 80 seconds.
The motor hums for about 1 second and stops.





Hey! 86,400 seconds per day / 360 degs =240 seconds passing during each degree of rotation?
240 / 80 sec = 3.. Does that mean I'm seeing 1/3 of a degree accuracy ?

That can't be right!
I hope that isn't going to be too hard on the West relay!

The Charger is keeping the new battery right up there.
That little 5-10 watt panel is working very well.
I'm thinking of hooking another charger (I have 2 spares) on to those PV
lines, to keep the old SUV battery up to par..
