First, I would recommend that you use Type194 in place of Type94
as it is a more robust model for simulating the performance of
thin-film PV technologies. If you are looking at crystalline silicon
PV then it is fine to continue using Type94. Second, Type94 does
take into account the negative impact of cell temperature on module
performance however, I imagine that there are other factors in your
change of location that overwhelm the impact of the cell
temperature. If you would like to send me the input file, I can have
a look at it.<br>
Kind regards,<br>

<div>Dear all,</div>
<div><br>
</div>
<div>I am trying to simulate a solar PV plant with type 94a in
different cities around the world. As known, the efficiency of
a pv module, decrease with the increasing of the ambient
temperature. It seems that the component doesn't take
properly into account this behaviour. In fact, for example, I
find a bigger average annual efficiency of solar field in
Ryiadh than in Napoli. I have also noticed that the changing
of the value of the parameter n. 8 (=Temperature coeficient of
Voc (ref. cond.)) does not produce any change in the output
power. </div>
<div>Do you know what is the reason for these inconsistencies?
Where I can finde the source code for this type to check the
equation used for the calculation (I don't find it in my
installation path)?</div>
<div><br>
</div>
<div>Thanks in advance for your help.</div>
