module ageing losses

[Alain]

How are the losses due to ageing of the modules taken into account in the simulation please ?

Hi Alain,

the module ageing losses (=degradation) are taken into account in the economic calculation only. The energy yield simulation is conducted for the first year only, without module ageing losses. You can refer to the energy balance after the simulation in order to see which losses are accounted for:

Hope that helps, kind regards,

Thank you Martin. I would like to know the degradation loss percentage considered every year by the software and if this is a value that can be edited by the user, please.

Hi Alain,

yes, the module degradation can be edited by the user:

There is no PV Modules menu in my model with a 3D design. How to reach these parameters in this case please ?

Hi Alain,

if you have a 3d project, the module degradation is accessible here:

Great. Thanks !
