Remember that your panels are connected in series and that if one gets shaded your entire row goes out, unless you are using micro inverters. You really need to do a shading study and if you use REVIT this can be done easily. When using a PV panel as a canopy or shading device you need to watch the summer time shading on your wall. Typically a long shadow on the wall by parapet or cornice might shade the panel, which is created by the noon day sun. Just push the panel a little further off the wall.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Best of luck to you and I hope it all works out.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><div><p class=MsoNormal><b><span lang=DE style='font-size:10.0pt;font-family:"ITC Avant Garde Std Bk","sans-serif";color:#1F497D;letter-spacing:1.0pt'>PETER HILLERMANN<o:p></o:p></span></b></p><p class=MsoNormal><span lang=DE style='font-size:10.0pt;font-family:"ITC Avant Garde Std Bk","sans-serif";color:#1F497D;letter-spacing:1.0pt'><o:p> </o:p></span></p><p class=MsoNormal><span lang=DE style='font-size:8.0pt;font-family:"ITC Avant Garde Gothic Demi";color:#1F497D;letter-spacing:1.0pt'><a href="mailto:peterh@westallarchitects.com">peterh@westallarchitects.com</a><o:p></o:p></span></p><p class=MsoNormal><span lang=DE style='font-size:10.0pt;font-family:"ITC Avant Garde Std Bk","sans-serif";color:#1F497D;letter-spacing:1.0pt'><o:p> </o:p></span></p><p class=MsoNormal style='line-height:75%'><b><span lang=DE style='font-size:14.0pt;line-height:75%;font-family:"ITC Avant Garde Std Md","sans-serif";color:#1F497D;letter-spacing:1.0pt'>westall</span></b><span lang=DE style='font-size:14.0pt;line-height:75%;color:#1F497D;letter-spacing:1.0pt'><o:p></o:p></span></p><p class=MsoNormal style='margin-left:4.0pt;line-height:75%'><b><span style='font-size:14.0pt;line-height:75%;font-family:"ITC Avant Garde Std Md","sans-serif";color:#1F497D;letter-spacing:1.0pt'>architects</span></b><span style='font-size:14.0pt;line-height:75%;font-family:"Calibri","sans-serif";color:#1F497D;letter-spacing:1.0pt'><o:p></o:p></span></p><p class=MsoNormal><span style='font-size:10.0pt;font-family:"ITC Avant Garde Std Bk","sans-serif";color:#1F497D;letter-spacing:1.0pt'>3404 pierce drive<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:10.0pt;font-family:"ITC Avant Garde Std Bk","sans-serif";color:#1F497D;letter-spacing:1.0pt'>chamblee, georgia 30341<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:8.0pt;font-family:"ITC Avant Garde Std Bk","sans-serif";color:#1F497D;letter-spacing:1.0pt'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:8.0pt;font-family:"ITC Avant Garde Std Bk","sans-serif";color:#1F497D;letter-spacing:1.0pt'>o 770.458.4113<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:8.0pt;font-family:"ITC Avant Garde Std Bk","sans-serif";color:#1F497D;letter-spacing:1.0pt'>f 770.458.5352<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:8.0pt;font-family:"ITC Avant Garde Std Bk","sans-serif";color:#1F497D;letter-spacing:1.0pt'>c 678.898.2936<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:8.0pt;font-family:"ITC Avant Garde Std Bk","sans-serif";color:#1F497D;letter-spacing:1.0pt'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:8.0pt;font-family:"ITC Avant Garde Gothic Demi";color:#1F497D;letter-spacing:1.0pt'>westallarchitects.com</span><span style='color:#1F497D;letter-spacing:1.0pt'><o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><img border=0 width=160 height=87 id="Picture_x0020_1" src="cid:image002.jpg@01CB7F41.1C392520" alt="Description: e-signature"><img border=0 width=92 height=90 id="Picture_x0020_2" src="cid:image005.gif@01CB7F40.D5B710D0" alt="Description: USGBC-Logo"><o:p></o:p></span></p></div><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><div><div style='border:none;border-top:solid #B5C4DF 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal><b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'>From:</span></b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'> equest-users-bounces@lists.onebuilding.org [mailto:equest-users-bounces@lists.onebuilding.org] <b>On Behalf Of </b>Alan Crittendon<br><b>Sent:</b> Monday, November 08, 2010 11:12 AM<br><b>To:</b> equest-users@lists.onebuilding.org<br><b>Subject:</b> [Equest-users] FW: Solar panels<o:p></o:p></span></p></div></div><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif";color:blue'>Is there a way to put power generation into equest?

PV watts is really good because it calculates panels all over the state using averages. It also depends on what system you are using. If you use a roof mount system that has a specific tilt you get a certain efficiency. If you use a system has trackers it becomes more efficient but the price might go up. Different states have different tilt angles to make their panels more efficient with the better degree of tilt. The thing I would do if you wanted to put it in eQuest is use PV watts calculator and apply it as a direct load that gives electricity to the building.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>PS: check to see what inverter you are using because different inverters have different efficiencies.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><div><p class=MsoNormal><b><span lang=DE style='font-size:10.0pt;font-family:"ITC Avant Garde Std Bk","sans-serif";color:#1F497D;letter-spacing:1.0pt'>PETER HILLERMANN<o:p></o:p></span></b></p><p class=MsoNormal><span lang=DE style='font-size:10.0pt;font-family:"ITC Avant Garde Std Bk","sans-serif";color:#1F497D;letter-spacing:1.0pt'><o:p> </o:p></span></p><p class=MsoNormal><span lang=DE style='font-size:8.0pt;font-family:"ITC Avant Garde Gothic Demi";color:#1F497D;letter-spacing:1.0pt'><a href="mailto:peterh@westallarchitects.com">peterh@westallarchitects.com</a><o:p></o:p></span></p><p class=MsoNormal><span lang=DE style='font-size:10.0pt;font-family:"ITC Avant Garde Std Bk","sans-serif";color:#1F497D;letter-spacing:1.0pt'><o:p> </o:p></span></p><p class=MsoNormal style='line-height:75%'><b><span lang=DE style='font-size:14.0pt;line-height:75%;font-family:"ITC Avant Garde Std Md","sans-serif";color:#1F497D;letter-spacing:1.0pt'>westall</span></b><span lang=DE style='font-size:14.0pt;line-height:75%;color:#1F497D;letter-spacing:1.0pt'><o:p></o:p></span></p><p class=MsoNormal style='margin-left:4.0pt;line-height:75%'><b><span style='font-size:14.0pt;line-height:75%;font-family:"ITC Avant Garde Std Md","sans-serif";color:#1F497D;letter-spacing:1.0pt'>architects</span></b><span style='font-size:14.0pt;line-height:75%;font-family:"Calibri","sans-serif";color:#1F497D;letter-spacing:1.0pt'><o:p></o:p></span></p><p class=MsoNormal><span style='font-size:10.0pt;font-family:"ITC Avant Garde Std Bk","sans-serif";color:#1F497D;letter-spacing:1.0pt'>3404 pierce drive<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:10.0pt;font-family:"ITC Avant Garde Std Bk","sans-serif";color:#1F497D;letter-spacing:1.0pt'>chamblee, georgia 30341<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:8.0pt;font-family:"ITC Avant Garde Std Bk","sans-serif";color:#1F497D;letter-spacing:1.0pt'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:8.0pt;font-family:"ITC Avant Garde Std Bk","sans-serif";color:#1F497D;letter-spacing:1.0pt'>o 770.458.4113<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:8.0pt;font-family:"ITC Avant Garde Std Bk","sans-serif";color:#1F497D;letter-spacing:1.0pt'>f 770.458.5352<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:8.0pt;font-family:"ITC Avant Garde Std Bk","sans-serif";color:#1F497D;letter-spacing:1.0pt'>c 678.898.2936<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:8.0pt;font-family:"ITC Avant Garde Std Bk","sans-serif";color:#1F497D;letter-spacing:1.0pt'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:8.0pt;font-family:"ITC Avant Garde Gothic Demi";color:#1F497D;letter-spacing:1.0pt'>westallarchitects.com</span><span style='color:#1F497D;letter-spacing:1.0pt'><o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><img border=0 width=160 height=87 id="Picture_x005f_x0020_1" src="cid:image006.jpg@01CB7F40.D5B710D0" alt="Description: e-signature"><img border=0 width=92 height=90 id="Picture_x005f_x0020_2" src="cid:image005.gif@01CB7F40.D5B710D0" alt="Description: USGBC-Logo"><o:p></o:p></span></p></div><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><div><div style='border:none;border-top:solid #B5C4DF 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal><b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'>From:</span></b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'> equest-users-bounces@lists.onebuilding.org [mailto:equest-users-bounces@lists.onebuilding.org] <b>On Behalf Of </b>Alan Crittendon<br><b>Sent:</b> Monday, November 08, 2010 8:43 AM<br><b>To:</b> equest-users@lists.onebuilding.org<br><b>Subject:</b> [Equest-users] Solar panels<o:p></o:p></span></p></div></div><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>I need to have about 5000ft of roof space dedicated to solar panels on a 41000ft roof.
