These are all good suggestions. Thank you for your responses.  I think I'll create a swale that will divert overflow to a culvert. Plant some ground cover in the swale and mulch with either wood chips and straw. Mint grows like a weed down in the Phoenix heat but wonder how cold hardy it is.  Temperature variations where this is located are 100F in summer and -5 in the winter.  Hopefully I can figure out a ground cover that will survive both extremes.    

What types of erosion control could I use under a solar array?  I have a 10 panel setup and over this last spring runoff has washed away parts of my driveway. The property is located in the Arizona high desert in a Juniper Pine forest, no grasses, lots of large rock and clay.  I'm considering installing a rain gutter under the panels and putting in a culvert to direct the water under the driveway.  I would prefer to harvest or use the water in some way but can't think of any real options.  Run off is on the Eastern side so I would be concerned about planting anything that could shade the panels.  I've included a photo to give you a general idea of what the area looks like. Unfortunately this is the best photo I have. It's old and doesn't show the area as completed but the run off is in this exact location.
