I have a question.
In the unlimited sheds,
I need to put number of string.
This is the number of sub-modules(cell strings) in a row(shed)?
Or it is the number of modules in parallel in a row?

The "Nb. of strings (transverse)" refers to the number of modules you have stacked in one table. But, if you are using MLPE such as microinverters or power optimizers, you need to specify the number of sub-modules, not modules. So for example, if you have a table that is 4 modules high, in landscape, then you will usually specify "4" in the Nb of strings. But, for the same system using SolarEdge power optimizers, for instance, you will specify "12" (because there are 3 sub-strings per module).

Thank you for your detailed information.
Here is one more question.
If I have one row with two strings(without MLPE), the number of strings is one or two?

Thank you.

If the number of string is the number of strings in the width of a row,
it should be one, isn't it?
(The case is one row with two strings without MLPE.)
