The Rserie specified in the parameters of the module is not the measured Rserie dV/dI
, but the intrinsic Rserie of the one-diode model.
It doesn't include the exponential contribution that you see on the graph below.
In the PV module's parameters dialog, the measured value dV/dI, named "Apparent Rserie
" is mentioned just below this value in the program.
When the Rserie is specified by manufacturers (as "measured Rserie"), it corresponds to this "apparent" value.
