I haven't had any off grid, adjustable roof mount systems in years, but
have one coming up. What is the best product these days?<br><br>
Thanks,<br><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>

Sunearth CompRail is an edge captive type railing that works great when
rear access is possible. Its positive steel to steel attachment with SS
bolts and threaded inserts is superior to Unirac Sunframe with its sheet
metal attachment screw mount.<br>

I am curious about what the rest of you are using for off-grid ground
mount <br>
racks. We need a tilt angle of 45 degrees.<br>
<br>
Thanks in advance.<br>
