For years we have used standard mounting racks like UniRac rails bolted
together with stainless-steel hardware. On larger arrays this usually means
bolting their extruded aluminum module rails to galvanized 3 pipe supports
for ground mounted arrays.

This is an amazingly timely post for me! I was just thinking of asking the
same question since i have a couple of ground mount installs coming up with
concrete pillars/galvanized anchor bolts/aluminum channel base. I notice
that DPW for example specs galvanized pipes to be attached with u-bolts
We use ss anchor (L) bolts when we need to bolt to pillars. Remember to
use an anti seize compound when installing initially.

I haven't used neoprene, but I usually use SS washers to isolate dissimilar
metals. Painted or powder coated steel doesn't always need this, but galvanized
definitely would. How careful we are with these issues is proportional to the
distance from the ocean. In New Mexico you can get away with

Since your'e embedding galvanized anchors in concrete remember that corrsion
of the zink content in the hot dipped galv plating is worse the higher the
pH of the concrete during the curing process. Very high pH in wet cement is
normal.
