PVsyst Bi-Facial Batch Mode Hourly Report Bug

[Helios210]

There would appear to be a bug for "Produced Energy" in the report generation when reports are generated during batch simulations and use bi-facial modules, please see the attached screenshot for an example.

Please explain what you think is a bug in the "Produced energy".

This normalized way of presenting the simulation data is indeed not well-suited for Bi-facial systems.

The additional energy (bifacial gain) is indeed added to the Ya value, i.e. deduced from the array losses La.

If sufficient, it could indeed lead to negative La values, and even PR values greater than one.

However I don't know any official definition of these normalized variables for describing the bi-facial systems.

Hi Andre,

Because the energy is given in W/year, which is absurd for a utility scale system, MWh or MW/year would make much more sense I think. This leads to a very large number indeed which as you can see extends across the page.

Best,

H.
