Solar panel rails.

June 8th, (while were having a garage sale!) Dave Merrill and his son came to install the solar array. Since our roof is a 10/12 pitch, (approximately 42 degrees), they used ropes tied onto the trees on the opposite side of the house and then to themselves to place all the rails and solar panels on the South side of the roof. I had to go into the attic to make sure all the rafters were at the correct distances. They place all the L brackets into the roof and sealed them with caulk. This picture shows the solar panel rails going up. The Uni-Rack system has a bolt that slides into the rail and a nut secures the rail to the L bracket. Each of our rails are 18 feet long which will accommodate 6 panels across. The rails are spaced with 1/4 of the length to the top and bottom of the rail and 1/2 the length between the rails in the middle.
