Something else, could you let me know how the shadow derating calculations of a face are determined? Is this based on a single string for the face (so that the worst performing module at a given time sets the minimum for the others) or is this based on a design with optimisers (performance of modules is independent of each other)? In any case it would be useful to have this option included in the software in order to come to an optimal system design or to calculate both shadow deratings. Besides that it would even be better to be able to select modules to be included for each independent MPPT string.
Cheers
