Electrical Loss acc. to strings

[Samuel]

Hi PVsyst, I'd like to know why is it the value on the electrical loss acc. to strings is zero even after applying proper partitions in the near shading section. Partitions are applied such that creating a rectangle to represent a whole string.

Hi,

It is difficult to evaluate without more information about your system and the layout, it could well be that there is not much shading and thus normal that the shading would be 0%. Please export your project as a .zip file to support@pvsyst.com if you wish that we have a closer look.

Kind regards

If there are no trees or objects that shade the modules, backtracking is on, and your system is flat, it will not have electrical shading loss.

Hi @dtarin, my model has no trees and with few objects (central inverters), backtracking is on and flat. Which maybe the reason why the electrical shading loss is zero but I have another variant with the same model but reduced number of panels but it does have -0.1% electrical shading loss. See below snips:

Express the report to second decimal to get clear picture, losses could be near zero and are being rounded.
