Impact the cell temperature on the voltage(Vmp)

Hi Esteban,

yes, when you use your own climate data, the ambient temperature (or environment temperature) must be included. In the simulation we then model the cell temperature based on the irradiance values and the environment temperature, depending on the installation type. The module temperature is then used as input for the electrical modelling of the PV devices which is of course also calculating the open circuit and MPP voltages. Actually, we are calculating the complete IV curve for every time step of the simulation, and that is always dependet on the actual irradiance that is incident on the module's surface and the module temperature.

If you want to know about the IV modelling, our help document would be a further source of information.

Kind regards,

Martin
