pole mount 150 watt modules [RE-wrenches]

[Travis Creswell, Ozark Solar]

It does pay to check for used pipe.  I recently bought two used ~18' pieces
of 8" Sch80 for $3/ft.  New Sch40 8' was running $15/ft and I would have had
to buy an 21' pieces.  Worked out perfect because I needed 8' under grade
and 10' above.

Speaking of array mounting pipes... Is anyone concerned about the long term
using standard pipe?  I've looked around a little for galvanized stuff but
all I could find was custom order and big bucks.  It's probably in the scrap
yard all the time but never when I am looking for it.  I take the time and
clean the pipe very well and use the "rust" zinc primer type paint before I
set the pipe.  Then, if time allows, I touch up the scratches that will be
under grade before I pour the concrete.  After I'm done I come along with a
high quality oil base paint and paint the pole.
