<DIV> </DIV>
<DIV>I have another question. i am working with the verison created in 1/1/97 and last modified in oct.2004 of type 536.</DIV>
<DIV>I have the concentrator connected to a weather data from a southern country and there is something I cant understand. I not only get lower temperatures than the ambience at night, but temperatures way below -273.15ºC, absolut cero. I checked out the "more" and it says that the range is (minus infinite,plus infinite). What is this supossed to mean? Am i doing something wrong? I tied to read the fortran code but I cant seem to fnid an explanation.</DIV>
<DIV> </DIV>
<DIV>Here are my connections:</DIV>
<DIV> </DIV>
<DIV>Type 109-TMY2 is connected to --> type 536 in the following matter:</DIV>
<DIV> </DIV>
<DIV>Ambient temperature --> Ambient temperature</DIV>
<DIV>Beam radiation on tilted surface --> incident beam radiation</DIV>
<DIV> </DIV>
<DIV>Best Regards, </DIV>

However, the Studio proforma for the Type 536<BR>model wil answer
your question. Using the "more" button next to the<BR>aperture area parameter will state whether the model is expecting the<BR>total array area or the area for one of the modules. If indeed the model<BR>you are using is looking for the area of one of the modules then the total<BR>area needed is indeed the area * #Series * #Parallel.<BR><BR>Jeff<BR><BR><BR><BR>Jeff Thornton<BR>President - TESS, LLC<BR><BR>2916 Marketplace Drive - Suite 104<BR>Madison WI 53719 USA<BR><BR>Phone: 608-274-2577<BR>Fax: 608-278-1475<BR>E-mail: <A href="mailto:thornton@tess-inc.com" ymailto="mailto:thornton@tess-inc.com">thornton@tess-inc.com</A><BR>Web: www.tess-inc.com<BR><BR></DIV></DIV></div><br>
