Module degradation

Hi you can have a look at https://www.pvsyst.com/help/ageing_general.htm

The STC maximum power point average degradation will be the same no matter the modules, if the ageing rate is the same (%/year). However, since different modules have different one diode model parameters, the same ageing rate may lead to different behaviours for conditions such as temperature behaviour or low-irradiance behaviour.

Then, if the plant has the same string layout, the mismatch degradation calculation will lead to the same mismatch due to the degradation (another loss that is due to ageing). But different stringing may lead to differences in the mismatch.
