I have adapted a  1/4 inch drive deep, 6 point socket onto a T-handled hand
tapping wrench. It makes for a balanced tightening tool for long spins of
the nuts onto the T bolts. The T handle is removable to easily stash in a
tool pouch.

Don't forget the anti-seize goop.

Hello Darryl,
I am a big fan of manually tightening all bolts and panel clips on any
array. I have done this on a MW tracker and racking systems on schools,
which were checked by a special inspector who required them to be hand
torqued and yes it's a lot, but in many peoples minds hand tightened is
worth it. I do know folks who use a cordless drill and turn the setting down
so as not to strip bolts and then go through and torque by hand. 

Mostly this is a personnel opinion on the process and wanted to relay my
experiences.

Hi all, I need advice
I am soon starting a 1000 module system, uning top down mounts, What power
tools will tighten to torque specification?  I will want to tighten each SS
1/4" nut on bolt to proper specs.  This is about 2000 bolts, so i want a
power tool, either air or battery electric, or electric that will tighten to
specification.

Thanks Darryl
