The PV panels are mounted to commercially available aluminum rails made for easy mounting of PV panels. There are two of these rails for each of the sets of 3 panels. The rails are supplied by companies like IronRidge or Unirac.
The front end of the rails are supported by a 6 by 6 treated timber which runs the full width of the PV array (with one splice).
The back of the rails that the PV panels are bolted to are supported by vertical aluminum legs, which are in turn supported by a 2nd 6 by 6 treated wood beam that runs along the full width at the back of the array. The tilt of the panels is set by the length of the vertical legs.
The two 6 by 6 timbers are in turn supported by concrete piers at about 8 ft intervals.

We viewed this PV mount at an open house for this very interesting home by Oasis Hybrid Homes...
Located in the Paradise Valley south of Livingston, MT -- one of the most beautiful valleys in MT.
