(P_actual/P_rated -1)*100

Positive result indicates gain, and is entered as a negative in PVsyst

The "Module quality loss+ is a parameter at your disposal, for any purpose.

Only the default value proposed by PVsyst is based on the PV module tolerance specification.
Please see the FAQ How to define the "Module quality loss" ?
