<p>David,</p>
<p> I am not sure which version of Trnsys you are using. However,
Type94 was found to have some problems like the one you describe
that were addressed with the release of Trnsys18 and Type103 (a
replacement for Type94).</p>
<p>kind regards,</p>
<p> David</p>

<p class="MsoNormal"><span lang="EN-US">I am trying to
understand the performance of Type 94 (Photovoltaic module).<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">I kept the default
parameters, in particular: Current at maximum power point =
5.9 A, and Voltage at maximum power point = 17 V.<o:p></o:p></span></p>
