[RE-wrenches] roof noise after solar install.

This was built at one time, but on Tuesday I am going to the site, and I will look very carefully at the structure.

We had a similar issue, which had more to do with the construction of the house than the rail span.  The system was on a 40' long array, but we had an expansion joint every 11' or so.  The issue with our popping sound mirrored yours (it would cause the noise in the morning and into the evening.  At our site, the noise occured at a location where a new addition had been attached to an older structure, and were not fastened together properly.  We resolved the issue by isolating the rail sets from each other where the two structures met.

 Thanks I missed that, but my longest run is just under 30'
