Rail Installation

The rails upon which the solar modules will be mounted were installed this week.  Here is the before:

And here is the after:

The rails are heavy duty aluminum.  L-shaped mounts attach to the roof every 4 feet.  The L-feet are attached to the roof by lag screw driven into a truss.  Sealant is applied to the lag screw and to the bottom of each L.  Altogether, it took about 5 hours to install the rails with two roofers, one rail assemblyman (me), and one 'supervisor'.  (That's a 40° roof!  There was no way I was going to get up there.

The conduit for the DC power leads will run just under the edge of the roof in the soffit.
