posts for ground mounting</DIV>
<DIV><BR></DIV>
<DIV style="FONT-FAMILY: Arial, sans-serif; FONT-SIZE: 10pt">
<DIV>We have an upcoming install for a residence subject to Homeowners
Association controls and they have demanded that the array be mounted on the
ground, not the roof. The client has a huge yard, but the south facing
yard area for the array slopes down fairly steeply. Of course this is
ideal for tilt angle so we can keep the array just high enough above the
ground to crawl under to wire and put down sheeting material to reduce grass
growing. </DIV>
<DIV> </DIV>
<DIV>However, this will be a real bear to get a tractor or Bobcat on
this steep slope to auger holes for the concrete piers, and then get
the concrete down to the pour. So I started checking and found a
company selling a self-drilling 2-1/2" galvanized pier that you auger into the
ground with a 3/4" drive wrench. After auger drills itself all the way
down, you add an extension tube that is adjustable in height. It would
be perfect for my application, but I am afraid its too good to be true.</DIV>
<DIV> </DIV>
<DIV>Here is a video link for the product.</DIV>

<DIV>My concern is will my racking start to move downhill if these posts
start to tilt over from the side loading, and will the pull out of the ground
from a major wind uplift.</DIV>
<DIV> </DIV>
