All Installed and wired,
Used a 2"x4" fabricated ramp to somewhat match the pitch of the roof. Aluminum angle brackets that I riveted to the bottom of the panels allowed me to slide the panel up the ramp, then hang it off the first rail of the rack, then I would get on the roof an put it into final position. No dead lifting
First two panels, slid into position.
Did the same for the remaining panels.
All up and connected
Hard to do as a one man job, but it worked out.
