I would like to know if there is a reason for not obtaining "electrical loss acc. to string" when using a Horizontal Tracking System and simulating as "According to Module Strings", regardless of the "fraction for electrical effect".
With fixed structures, there is "electrical loss acc. to string" when simulating as "According to Module Strings", since shadows generate mismatch of electrical response of the modules in series and strings in parallel.
I was expecting the same for Horizontal Tracking Systems (despite backtracking) since once there are shadows ("near shadings: irradiance loss" is not 0), the mismatch of electrical response of the modules would cause a loss.
