<p>Farah,</p>
<p> I see that you also copied your message to our techsupport
hotline; could you please also send the project files over there?</p>
<p> Sometimes in the very early morning or very late afternoon the
definition for the efficiency makes two very small numbers divided
by each other result in an unrealistically high value. With
efficiencies, it is often best to look at averages (daily or
longer) rather than at instantaneous values. That said, I'd still
like to verify that there is not a problem in the model.</p>
<p>kind regards,</p>
<p> David</p>

<div>I am using type 103 to model a PV panel,</div>
<div>However the efficiency of the array is not an input, but
could be found in the outputs. I am getting efficiency values
up to 60. What does it mean ? knowing that the efficiency of
PV panels is between 15 and 20 % ( from the literature).</div>
