So I'm installing solar roof tiles but unfortunately I have a dormer window in my roof so some of my solar roof tiles will be shaded for part of the day (see photo below).
The solar tiles are Planum PV from Nelskamp in Germany, their technical data;
I haven't had any luck speaking with local 'solar experts' about this topic (solar tiles and/or optimizers are clearly not popular yet it seems) so I'm wondering if I anyone has some useful input/ideas here...
Below is a roof layout plan which shows the areas where I think TS4-A-O optimizers should be placed. I plan to wire between 2 and 4 solar tiles in series and then connect each group of tiles to an optimizer, purchasing 6 optimizers in total, is this a valid plan?
Or, do I need to purchase a separate optimizer per module?
I don't think a separate module would work because the volts output/Vmp of a single module is not in-between the threshold of 16 to 90 Volts that the TS4-A-O can handle and in addition a single optimizer per module is going to work out as very expensive...
Here is the shading 'in action' at 08:30 CET just to complete the picture;
Thanks in advance for any input, but go easy as I haven't done much electrical engineering for 20 years...

- Max power output = 90Wp
- Vmp = 10.02 V
- Imp = 9.01 A
- Voc = 11.97 V
- Isc = 9.70 A
