Mount the PVs
Once the rack is assembled, it’s time to install the PVs. If you’re assembling the array while it’s fixed in a tilted position, install the bottom row of PVs first. Then you can rest the next row of modules on the first row while you’re positioning them, which makes the job faster and easier.
The mounting hardware for the PVs will be included with the rack, not the modules. This hardware should be stainless steel to resist corrosion, and include either lock washers or lock nuts that will not loosen over time. It’s easier to work with the mounting hardware if you insert the bolts through the module mounting holes from the inside of the PVs, and then through the rack. This gives you better clearance to get the washers and nuts in place.
An open-end wrench used in conjunction with a ratchet and socket (usually 7/16 inch) will allow you to quickly fasten the PVs to the rack. If you have a big array, or several to install, a cordless drill fitted with a socket driver will definitely speed up the job. If you use this approach, make sure to set the driver’s clutch to release before the hardware is overtightened. If you don’t, you may snap off bolts.
