High Value of Performance Ratio

[yovandeer]

Hello everyone

I have currently created a PV project and run a simulation. However when analyzing the results of the simulation I noticed that my performance ratio has a value of 171%, which is basically impossible.

The report of my project is in attached file.

Could anyone help me?

Kind regards

Yoline

Hi Yoline,

I guess you have used bifacial module. PVsyst does not take 'rear side irradiation' into account in the calculation of PR. That's the reason for such high value of PR.

Hope it clarifies your doubt.
