Pat and Lee visit

Pat and Lee came to look over the proposed installation site today. I want the array placed on the roof of my metal barn/garage instead of the main house because the barn has a metal roof vs shingles on the house. The barn roof has an ideal southern facing, although the slope is only about 15 degrees. According to Pat, the ideal slope is equal to the latitude, which would be about 35 degrees. He was not overly concerned about this, however, because it only accounts for a few % loss in efficiency. Lee had already spec'd out the probable run for the electrical cables from the barn to the main house using Google Earth. There appeared to be no showstoppers with the location I wanted. The minor concerns included a county requirement to have 3 feet of access around every side of the array. This would severely limit the total space available on the roof which is about 12.5' x 36'. Pat thought he could get the county to relax this requirement since every side is accessible by ladder. I also mentioned that the barn was not permitted during construction (I built it myself) but that I did have plans, which I sent with Pat and Lee.
