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.
