I include below two images. The ist was taken at 22h15 last night and showed that the batteries were on 83%.
The second was taken at 06h15 this morning and the SOC was 78%
You'll notice the efficiency of my household all with low energy devices, etc. Note that this includes running 3 refrigerators one of which is on a timer and shuts down for 4 hours in the middle of the night. That's in my bar, a normal sized upright Kelvinator that keeps my beer cold.

 
Note that at the time of this, all 3 refridgerators were turned on. We seldom exceed more than 700W at any given moment.

I don't really care too much about the power that still goes to waste, as I also initially attempted to harvest that. I soon enough realised the only way to do that would be through adding more storage, and that does not make economic sense to me. So I have made peace with that fact.
Yet our two approaches are quite similar. In my case all I have done is to limit consumption from batteries and to maximise consumption from the excess PV wattage once the batteries are full. This approach does seem to be advantageous.
At some stage the AGM batteries will have to be replaced, and only then will I bother to add something longer lasting. Hopefully the current trend of renewables getting cheaper will continue but our ever-weakening currency unfortunately does add a curved ball.
One last point. We have become so focused on efficiency that I manage to get our two battery packs full by 10h30 at the moment. This obviously depends on the quality of the daily yield.

That’s very coincidental. My 10KW system also charges the batteries by 12 noon and after that we desperately try to use the excess power washing and drying clothes plus running a split AC in the bedroom all day.  I still see that about 33% of the power still goes to waste.

Could be a broken diode. Either way, moving the chimney is probably the best solution.

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.
