<p class="MsoNormal"><span style="font-family:"Verdana","sans-serif";color:#1f497d">My
earlier reply may have been a bit facetious. What I meant
by it was that big-box solar contractors can be lazy when it
comes to solar design. They will rely totally on satellite
imagery and not check the design on the ground. This is how
you get solar proposed for shaded areas, where skylights and
roof vents are located, or overhanging thin air. This may
be what is happening in the image you shared. </span></p>
<p class="MsoNormal"><span style="font-family:"Verdana","sans-serif";color:#1f497d"> </span></p>
<p class="MsoNormal"><span style="font-family:"Verdana","sans-serif";color:#1f497d">What
is unique here is someone actually specified overhanging
panels. Looking more closely at the image, a roof outline
is shown but it is not clear that the outline is actually
situated over a building. It almost looks like there is
landscaped area inside the outline.</span></p>
<p class="MsoNormal"><span style="font-family:"Verdana","sans-serif";color:#1f497d"> </span></p>
<p class="MsoNormal"><span style="font-family:"Verdana","sans-serif";color:#1f497d">The
solution of course is to get on out there, measure the roof
and any obstructions and analyze the shading. I use the <a href="https://apps.apple.com/us/app/sun-seeker-tracker-surveyor/id330247123" moz-do-not-send="true">Sun Seeker</a> app for IOS for the
shading analysis.</span></p>
