Different losses depending on how to obtain them

[sergio.espada]

Hello!

Recently I tested a comparison of getting the values in W of one variable and the difference between Energies injected to grid.

I chose, for instance, LID loss. I did a simulation with LID loss=0% and got the hourly results of E_Grid. Then I did the same with LID loss=2% and I got the hourly results of MisLoss too. According to that, the difference between E_Grid(LID=0%) and E_Grid(LID=2%) is not the same as hourly LID loss obtained.

I don't know why this happens and which result is more reliable becuase I tried to obtain PR result from both data and the difference of energies seems the right one.

Does anyone know if PVsyst calculate loss variables other way or take other things into account?

Thank you.
