[EnergyPlus_Support] Fatal Error: Photovoltaic (EquivalentOne-Diode) ..

[Sarah Al Jarallah <sarahalghamdi@xxxxxxxxx>]

Dear all,

At the mean time, Iâ??m modeling a single-family house with PV system by using the (PhotovoltaicPerformance:EquivalentOne-Diode) type ..  At first, I tried the PV characteristics given in example file "GeneratorwithPV" where the simulation went smoothly and I got results.  But when I used PV characteristics(attached) from a catalogue I got fatal 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) = -7519.13932

   **   ~~~   ** II (current) = 0.00000

   **  Fatal  ** FUN: EnergyPlus terminates because of numerical problem in EquivalentOne-Diode PV model 

 

I would appreciate your help..

Thank you ..
