Best Practices for PV Mounted on Roof - Looking for Install Feedback

[Old_Skewler]

The array was installed with IronRidge mounting racks. I tried using their "cable management" clips but honestly I couldn't figure out how to properly use them.

I am trying to understand whether these wires on the ground are acceptable or if I need to do something about them. Here are the photos of my install. Any constructive feedback is welcome:

The Ironridge wire clips snap into the top groove of the rail. The wiring should be in conduit.
