the temperature of shaded solar cell

[Chen]

Dear PVsyst team：

   when some solar cell is partial shaded，how to calculate its temperature as shown in the following figure, thanks!

In this tool, PVsyst tries to evaluate the temperature of the reverse-biased cell, as a function of the power consumed in this cell and the U-value (with resp. to 25° ambient).

In this case this is not dangerous, but in usual modules the cell temperature may become very high: this is the hot spot problem.
