Unlimited Tracker, horiz.axis

[Aboeyad]

Hi PVsyst team,

Why when I click on "Backtracking" option then the option "Electrical effect" is disappeared?  Does that mean if I click on Backtracking then Electrical effect will not be activated?   

Thank you in advance

Indeed it is normal. With the unlimited trackers field type we assume a perfect backtracking and therefor there will be no mutual shadings.

It is clear, Thank you for the answer.
