<div dir="ltr"><br><div>William - I agree that the condition of the roof and electrical service should be inspected before installation, but for some installers its helpful to have an accurate shade analysis prior to visiting the site. I don't think the use of a cost-effective technology implies that the installer is cheap or unwilling to do the diligence required for proper system design. And if a company has entry level installers leading jobs I think they likely have bigger issues on their hands. </div><div><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><br><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><br><div><br></div><div><div><p class="MsoNormal"><span style="color:rgb(56,118,29)">For a brighter energy future,<br>

If a contractor cannot be bothered to get on a roof to provide an accurate assessment of the site, I wonder if they will be honest if it turns out there are shading or other issues not anticipated? The entry level installer will never notice shading problems. If there are undocumented shading issues, the consumer may never know they are being cheated out of some of the return on their investment.</span></p><p class="MsoNormal"><span style="font-family:"Arial","sans-serif";color:black"> </span></p><p class="MsoNormal"><span style="font-family:"Arial","sans-serif";color:black">This is true also about the condition of the roof and electrical infrastructure.

These tools can typically make it possible to generate a full rendering and shade analysis in less than 15 minutes for the experienced user, without ever having to get on a roof. NREL did some validation studies (<a href="http://www.nrel.gov/docs/fy16osti/65558.pdf" target="_blank">here's Aurora's</a>) and found a few tools to produce results as good or better than the SunEye, which makes sense to me since the analysis is based on an integral over the whole roof surface as opposed to a few point measurements. Of course the "garbage in, garbage out" principle is very applicable.</p></div><div><div><div><p class="MsoNormal"> </p></div><div><div><div><div><div><div><div><p class="MsoNormal"> </p><div><div><div><div><p class="MsoNormal"> </p><div><p class="MsoNormal"> </p></div><div><div><p class="MsoNormal"><span style="color:#38761d">For a brighter energy future,<br><br><br>Andrew Truitt </span></p></div><div><p class="MsoNormal"><span style="color:#38761d">Principal<br>Truitt Renewable Energy Consulting, LLC</span></p></div><div><p class="MsoNormal"><span style="color:#38761d"><a href="tel:%28202%29%20486-7507" target="_blank">(202) 486-7507</a></span></p><p class="MsoNormal"><a href="https://www.linkedin.com/in/andrewtruitt" target="_blank">LinkedIn Profile</a></p><p class="MsoNormal"><a href="http://truittreconsulting.weebly.com/" target="_blank">Company Website</a></p><p class="MsoNormal"><span style="color:#38761d">NABCEP Certified PV Installation Professional ID: 032407-66</span></p><p class="MsoNormal"><span style="color:#38761d">Colorado Journeyman Electrician License No.: 600132</span></p></div></div></div></div></div></div></div></div><div><div><div><div><div><p><span style="color:#147dba"><img border="0" width="200" height="133" src="cid:image005.jpg@01D17881.C6B7BEA0" alt="24 copy.jpg"></span><br><span style="color:#147dba"><br></span>"Don't get me wrong: I love nuclear energy!
