P50 by default

[Barbadori]

Hi there,

I don't have much experience on P50, P90, etc... my question is: when running a normal simulation without using the P50-P90 estimation tool, is the energy annual yield obtained as a result of that simulation the P50 value?

In other words, all simulations provide P50 value by default and the P50-P90 estimation tool is only to be used when we want to know P90, P75, etc... Is this correct?

Many thanks in advance.

It will depend on your weather file. If you are using a standard TMY file (CPR, SolarGIS, etc), it will be a P50 result.

I use measured data most of the time. How would that change the PXX?

Thanks in advance.
