That’s not the case with the deck however, so connection to anything but the columns will likely require structural reinforcement. Attachment to the deck may also impede maintenance such as plowing (not sure if that is an issue in your area), and could take parking spaces out of service that are often more valuable than the energy produced by the array.<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'>In addition to the solid and relevant advice already given by others, I would recommend aligning yourself with a reputable SE firm that has design experience parking garages, and a racking company and/or steel fabricator that can advise on what is possible for your specific site. A prefab carport system may be an attractive solution, but contrary to what their sales people might tell you it will likely not pass structural when installed on top of a parking garage without significant structural reinforcement. <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'>Good luck!<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:#44546A'>Garrison Riegel<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#44546A'>PV Operations Manager | </span><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><a href="http://www.solarserviceinc.com/"><i><span style='color:#222A35'>Solar Service Inc</span></i></a></span><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#44546A'><o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#44546A'>[p] 847-677-0950 | </span><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><a href="mailto:garrison@solarserviceinc.com"><span style='color:#44546A;text-decoration:none'>garrison@solarserviceinc.com</span></a></span><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#44546A'><o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#44546A'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#44546A'>NABCEP Certified PV Installation Professional™<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'><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><div style='border:none;border-top:solid #E1E1E1 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal><b><span style='font-size:11.0pt;font-family:"Calibri","sans-serif"'>From:</span></b><span style='font-size:11.0pt;font-family:"Calibri","sans-serif"'> re-wrenches-bounces@lists.re-wrenches.org [mailto:re-wrenches-bounces@lists.re-wrenches.org] <b>On Behalf Of </b>David Brearley<br><b>Sent:</b> Wednesday, February 05, 2014 9:04 PM<br><b>To:</b> RE-wrenches<br><b>Subject:</b> Re: [RE-wrenches] Solar Carport on a Parking Ramp<o:p></o:p></span></p></div></div><p class=MsoNormal><o:p> </o:p></p><div><p class=MsoNormal>Hi Karl,<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>Besides working with a PE, you may need to Xray the concrete to determine a connection detail that won't compromise any reinforcing steel in the concrete.<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>The SPG Solar case study in this article may be relevant:<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal><a href="http://bit.ly/1e4LCKd">http://bit.ly/1e4LCKd</a><o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>(The link to the case study is next to the photo, under the text "Inside this Article."
