Hello everyone,

If degradation is included in the simulation so as to calculate the output for a specific year, why PVsyst considers the same LID loss factor in year X as in year 0? As I can see the different variants, LID is counted every year and, in my opinion, that is false. Has anyone solved this? Thank you in advance.

Best Regards,
Eduardo

The LID is an initial degradation of the PV module's performance, arising during the first hours of exposition.
It is obviously not "recovered" at the end of the first year !
The degradation is permanent, this means that it has indeed to be applied to each simulation for each year.
