Day is done. As always, I was impressed with their concern for aesthetics. E.F. told me with pride that the panels on the main roof would be centered, with 17 inches of roof on each side.
Incidentally, the twelve panels on the garage roof aren't centered because main roof casts a shadow on the side in late afternoon (or mid afternoon in winter).
The project electrician, R., came by this afternoon after a 65 mile bike ride at the Jersey Shore. He was planning his electrical work that will be done early next week. He, too, is very concerned with making the job look as aesthetically pleasing as possible. Can't complain about that.
