Thanks for posting. 
This:
is probably why I won't do it.
Even if you get every fastener into a rafter, the constant heating and cooling of the fasteners will lead to expansion. Expansion and contraction of the fastener, coupled with wind-load (pulling and pushing) on the panel will lead to movement.
Thus, leaks.

My neighbor is currently trying to find someone to sue over the water damage caused by leaks created by a solar panel installation, it was done several years ago and the business that did the install is long gone. Seems to be a lot of roof problems occurring now that these installations have some years on them.

Not if you go with a company that knows wtf they are doing.
Standing Seam is the easiest and there are no penetrations. But for wood shake, asphalt and aluminum shingles you would use what's called Quick Mount, a counter flashing. This is what it looks like
Up close
That "block" keeps the lag bolt, which is "hurricane rated" stainless steel btw, above the roof penetration. Water cannot possibly get into the lag. Again though, use a company that knows what they are doing.
