You can check to make sure it's doing as you hope by plotting the slope and azimuth of the collector from the weather component.</div><div><br></div><div>Jeff Thornton</div><div>TESS<br><br>Sent from my iPhone</div><div><br>On Apr 17, 2015, at 5:38 PM, MERIEM SOUSSI <<a href="mailto:soussi_meriem2005@yahoo.fr">soussi_meriem2005@yahoo.fr</a>> wrote:<br><br></div><blockquote type="cite"><div><div style="color:#000; background-color:#fff; font-family:HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif;font-size:14px"><div id="yui_3_16_0_1_1429224503523_9881" class="y_msg_container"><div id="yiv1039778359"><div id="yui_3_16_0_1_1429224503523_9883"><div id="yui_3_16_0_1_1429224503523_9882" style="color:#000;background-color:#fff;font-family:HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif;font-size:14px;"><div dir="ltr" id="yiv1039778359yui_3_16_0_1_1429118113860_7682"><div dir="ltr"><span id="yiv1039778359yui_3_16_0_1_1429118113860_7688"><font size="2"><font face="Arial">Dear Trnsys-users</font></font>,</span></div></div><div id="yiv1039778359yui_3_16_0_1_1429118113860_7695" dir="ltr"><span id="yiv1039778359yui_3_16_0_1_1429118113860_7688">I am modelling a tracking trough solar collector.
