Hi, I'm an engineering student and I'm using Design Builder to make a school comfort simulation; it's my first time using this software. I tried to run the simulation, but it stops for the following 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) = -1173.26334
** ~~~ ** II (current) = -18315151218489725896622080.00000
** Fatal ** FUN: EnergyPlus terminates because of numerical problem in EquivalentOne-Diode PV model
I assume that the problem is related to the modeling of the panel. The program gives me the ability to model only one diode panels, but in my project there is a three diode panel. In this link there are panel datasheet: https://www.x-win.it/wp-content/uploads/2021/03/LR4-60HPH-350-380M%EF%BC%88NEW-Hi-MO4%EF%BC%89Italian.pdf
