I'll try and get some pictures of my tilt rack design for my neighbors soon, Glort. Possibly tomorrow if my leg is better.
I'm in AZ so steel racks hold up just fine here. We just bolt the angle iron frame directly to the PV panel aluminum channel. I laugh when I see the prices for store bought mounting racks and hardware.
We are in a very remote, rural area so we are concerned about function, not appearance. Your area is very different. We have no "councils" meeting unless the natives are angry
. Seriously, the Apaches are to the south, Zuni to the East, Navajo to the north just past the Petrified Forest, Hopi NE. My land has much worked stone from the Pueblo related people who lived here 1000 years ago and is covered by both marine fossils and softball to basketball sized volcanic rocks as well as some large petrified logs.
