Since the detection of far shadows is done in one place, it is
assumed that the approximation to be valid for the entire system.
This approximation is definitely acceptable if the system is realized
on a limited extension.
BlueSol allows multiple measurements to be made of the diagram shade
in most places on the site of the photovoltaic installation will
create more than one diagram of shading.
For
each shading is assigned a name to be referenced in the definition
of strings of the system, so as to specify that the string is applied
to a particular shading.
