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

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
