Information

Detailed physical model of photovoltaic panel (thermal capacity)

Hypothesis and equations

Model to calculate: module temperature, instantaneous electric power and cumulative PV production

This model considers:

• the photovoltaic panel thermal capacity
• exchanges by forced convection due to wind on front face
• exchanges by free convection on the back face in the case of a photovoltaic field. This is a non-linear convective model and
• exchanges by LW radiation with the sky and the environment
• SW radiation received by the PV panel from the sun (consideration of optical reflexion losses and conversion into electricity of a part of this incident radiation)

The photovoltaic efficiency is calculated by the EfficiencyFunctionOfTemp model.

Instructions for use

none

Known limits / Use precautions

This model has the advantage of being detailed in terms of physical reality while reducing the computation time (by grouping all layers of the PV panel in a single thermal capacity).

Warning ! Up to now, this model can be used only for a crystalline silicon technology. For other technologies, use PVPanelNOCT model and read the user manual.
