PhotovoltaicPerformance:EquivalentOneDiode Severe Error
I am trying to run panels described in the California Energy Comission Database https://www.energy.ca.gov/media/2367 Most panels produce a fatal crash in EnergyPlus using the OneDiode model. I am using EnergyPlus Version 23.1.0-87ed9199d4
* 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) = 17.15636 * ~~~ * II (current) = -3335.62140 * Fatal * FUN: EnergyPlus terminates because of numerical problem in EquivalentOne-Diode PV model
...Summary of Errors that led to program termination: ..... Reference severe error count=1
Is this model not maintained anymore? It seems unusable with more modern panels unless I am missing something.
Here are two panel descriptions -> Panel0 works, Panel1 causes the crash.
