I am in the process of putting in a 24 panel system on a brand new Spanish tile clay roof and the hooks have already been installed.
I did extensive research on tile mounting and found out a few things.   Do not grind down the tile on the bottom, it would make no difference unless you can lower the hook down further which is probably not likely.  In any case it is recommended that you only grind of a channel in the top tile and just enough that the tile rest a bit lower.  You will must have a gap at the bottom as the bottom tile cannot move and it will be cracked if the wind pushes the panels downward and hits into a tile that is resting on the batten.  The top tile can move so long as the nail or screw holding it at the rear is not tightened too much.  So the hook touching the top tile is not a big issue.
 
Bottom line is that there is always going to be some Gaps on the tiles that have the hooks under them.  You can minimize that with some grinding of the top tile but do not try to grind out too much or the tile will crack when the hook moves with the wind.
 
BTW the tiles on the roof do not stop all of the water when it rains.  There is always water getting blown under every tile and many roofs have several cracked tiles.  What makes a tile roof water resistant is the membrane or Felt that is under the tiles.  Even a roof with perfect tiles will leak if the membrane underneath it has a tear in it.  So don't worry to much about water getting blown under the tile.  If your membrane is good it will just run off the side of the roof.

I'm going to see what the installer says when he comes to complete the job.  This roof is directly over my front door and when standing on the porch it just looks wrong.  I would hate to see that everyday, I rather have it sorted out now then later.
 

I'm in JHB, had lots of rain and winds since my installation and trust me, my house has no leaks at all. To get water leak through those gaps, you will have to physically spray water there with hose pipe or something. Normal/crosswind rain will not enter, it has not so far. Ten months later and counting 

Nice, video though. Interesting to know how to do the installation properly but I wouldn't loose sleep over the gaps. In your case, you have paid the installer, let him fix it properly 😃

I literally went into my roof when we had those heavy windy rains in JHB that up routed trees around our area in the Northern Suburbs. Inspected all my roof hooks mounting and there was not a single drop of rain coming through 

Will also plan to fix mine too, now that I know how its done. Thank you for the info, we learn every day 😃

Planning to re-arrange them because I need to add more. Need to create space for 12 more 

Not with "normal" rain. But with driving rain that happens to come from the wrong direction, rain will enter through the gap, and won't if the job was done properly.
It's just extreme cost cutting. Not a good sign.
Edit: it will be a huge job to fix it now. Much more than doing it properly in the first place.

mine are like that, but then again I did the installation myself. If I had paid someone to do the installation, I would demand that they fix the gap properly. Grind the tile as @Branisays 
But to be honest, nothing will happen if left like that. The re no leak on my roof so, no need to worry about tiles that are slightly lifted 😃
