[RE-wrenches] Vertical wall, shared rails

[Dana Solar work]

I have taken adjustable
ground mount racks & flipped them upside down. They work great as long as you got something safe to bolt securely to like unistrut or through like concrete.

Hello Wrenches,
Wondering if any of you have ever done anything similar to installing on a vertical wall using a horizontal shared rail racking system, array being about 32.8m (110') wide and 26.3m (86') tall

The rails obviously have to be exactly perpendicular the entire length so we are taking extra care that the first row (top row) is true and using template spacers for each row down.  Only problem is that the top of the building is a concrete parapet and anything but level.

Wondering if anyone has any good tips for getting that top row level/square and  keeping the rest of the rails perfectly perpendicular? (keeping in mind the length...32.8m (110')

Much Thanks,
