Was going to ask the same thing! Is this part of a proprietary PV mounting system? It looks a little flimsy to me and I'd be concerned about wind loading amongst other things. It just doesn't look strong enough to me.
Incidentally, I mentioned drilling through slates to mount rails to the roofing contractor we use on our installs. He screwed his face up. I can't tell you what he said since I believe this forum has a pretty good swear filter. Suffice to say, he didn't think much to it.
I have around 50 install under my belt, and I have used various types of mounting systems, and to be honest the hanger bolts sit tighter than your normal roof anchors.
