I have this really fantastic mechanical design for tracking the sun.
Been working on it for several years. I have tried some commercial
available sensors, but so far I found the all work but some have
reliability problems. My sensor must work from 11- 21 VDC and turn my
gear motor which is rated at 300mA. It does not have to be super
accurate but super reliable.

try Zome works in New Mexico. theirs works with out electricity at least on
one axis.

I've had better results with Wattsun than Zomeworks.  Zome doesn't use
electricity but last I checked it does use freon which is not exactly
environmentally benign

 Have you actually USED both?

We have installed many trackers, and both leave something to be desired for
reliability, but the Wattsun had far more problems with the motor than the
Zomeworks did with the freon cyclinders. And if you think that a few dozen
freon cylinders is going to make much of a difference compared to the 300
million + estimated OTHER items that still have freon such as old
refrigerators and auto AC, you are living in a dream world.
