This Job was a bit more customized because the roof was not plumb and old. We had to reinforce the mounting structure with U-strut. The panels were spaced from left to right, 2, 5, and 5 due to the vent pipes. The array has two strings of 12 panels. Surprisingly, the roof looks alot better with the panels.
On this roof, we can see the conduit with four conductor awg #14. The array has 12 sanyo with microinverters. The cable coming from the last inverter is attached with the line side #14s' to a double pull switch. The switch has metal, therefore, a ground green is attached to the switch housing. The line side has both the black and red. The load side or PV source side attaches to the other side. Enjoy
