For someone building this sort of system, this looks like a good deal - I don't think I could buy the actuators plus the raw electronic components for that price, and this is an already-built control system.

I hadn't noticed the force spec - interesting.
That's pretty good for a small actuator, so they didn't go for the smallest/cheapest unit. With the limited travel (leverage is important) and a potentially large panel area in a wind, this sort of drive capacity seems roughly suitable to me.
The tracker discussion is interesting, but I think a tracking panel really only makes sense with an RV for someone who is interested in it as a hobby. It's good that people have lots of interesting hobbies!
