A method is provided for calculating a performance of a photovoltaic module comprising at least a first photovoltaic cell and a second photovoltaic cell. The method comprises calculating a heat flow between the first photovoltaic cell and the second photovoltaic cell using a first thermal equivalent circuit of the first photovoltaic cell and a second thermal equivalent circuit of the second photovoltaic cell, wherein at least one node of the first thermal equivalent circuit is connected to a corresponding node of the second thermal equivalent circuit by a thermal coupling resistance. The method may be used for calculating the influence of spatial and temporal variations in the operation conditions on the performance, such as the energy yield, of a photovoltaic module or a photovoltaic system.
