pv loss due to temperature

[fabrice]

1. why PV loss due to temperature shows different values every time the simulation is run ? why the value is not consistent ?

[André Mermoud]

The temperature loss depends on:

- The Ambient temperature,

- The array temperature, related to the ambient with irradiance and eventual wind velocity, according to your Uc and Uv values.

- The PV module temperature behavior (according to the one-diode model).

To my knowing, the temperature loss is stable when repeating the simulation.

Please explain in what is is not consistent.

Hii,

It is also my observation that PV loss due to temperature is not consistent and is varying with tilt in one my simulation. The location is of Orissa in India.

Please explain.

[André Mermoud]

The array temperature is calculated from the GlobInc (irradiance on the PV plane. Therefore it is quite normal that it is different with different orientations.
