Hello. I'm trying to run a PV model, but there is a problem in calculation of Max power using one-diode model. The data I used for PV model is from a catalog. Is there a way to solve this problem?

The error message is as follows:

* 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) = -1113.36423 * ~~~ * II (current) = -1.21086E+025 * Fatal * FUN: EnergyPlus terminates because of numerical problem in EquivalentOne-Diode PV

Also, I have attached the input data of the model. I think, the problem is due to the values of shunt resistance and/or semiconductor band-gap because I left their as default values (of DesignBuilder software), but other electrical input data are from a catalog.
