Post #9033

Worked on the neighbor's solar arrays today. A week or two ago, we build one array out of three just to make sure I didn't miss anything on the CAD drawing. Yesterday we augered and installed 8 posts so the ends of the two additional arrays would ser firm today. Today we augered 28 holes and set 7 posts. Now the perimeter posts are done and we can eaily "grid off" the interior posts with a couple of string lines. 21 posts let to set and we are done with concrete. For those playing along on the home game, each 60' long array holds 16 panels. These panels end up being just under 45" wide and once we add the gap between for panel clamps they are almost exactly 45". We put down 9 pairs of posts on 7'6" centers. The two rows are 4' apart. These panels are quite heavy and we're using 2-3/8" sched 40 fence posts which are also quite heavy. we are using 240lbs of concrete per leg as ballast. So thats 72 forty pound bags of concrete per array.
