William,<br>
All of our off grid is residential. In general we never do ground
mount for off grid. With rare and specific exception we use pole-top
racking. This is simply because pole top racks hold the entire array
in balance over a single pivot, making seasonal adjustment easy for
one person. Ground mount puts the pivot at the bottom edge of an
array, requiring at least two people to adjust: one or more to lift
and one to loosen/tighten the leg sliders. <br>
<br>
Knowing the depth of your professional competence, you know this
already, and this request is about a specific job. But most off-grid
Wrenches may be in the same case, and thus not able to easily answer
your question.<br>
<br>
Having used UniRac a few times for adjustable roof/ground racking, I
certainly would recommend against their adjustable tilt legs. Too
easy for homeowners to loosen the pinch bolt too far and lose the
twist-nut. In years past (I haven't used it in recent years)
DP&W made good adjustable racking.<br>
