PVT and equivalent one diode photovoltaic performance model

I am modeling a PVT system on EnergyPlus, when I use Equivalent One Diode photovoltaic performance model I got this Severe error:

** Severe  ** EquivalentOneDiode Photovoltaic model failed to find maximum power point
   **   ~~~   ** Numerical solver failed trying to take exponential of too large a number
   **   ~~~   ** Check input data in PhotovoltaicPerformance:EquivalentOne-Diode
   **   ~~~   ** VV (voltage) = 0.00000
   **   ~~~   ** II (current) = 0.13234
   **  Fatal  ** FUN: EnergyPlus terminates because of numerical problem in EquivalentOne-Diode PV model

To note that I've got the model parameters from manufacturer sheet. Instead, I tried PhotovoltaicPerformance:Simple model and the file run with no errors. Is there a way to fix this error? Thanks
