Hi, in what way? The loading is obviously less, and the clamps are
rated for the load.

I've designed and installed several thousand cantilevered arrays over

code changes have taken a turn for the worse in most jurisdictions
and oftentimes disallow cantilevering.

I've done a fair amount of roof mounted solar structural compliance,

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.
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.
The solution of course is to get on out there, measure the roof and
any obstructions and analyze the shading. I use the Sun Seeker
<https://apps.apple.com/us/app/sun-seeker-tracker-surveyor/id330247123>
app for IOS for the shading analysis.

Are you sure that's what you're looking at? To me, that looks
like there was an addition made to the house, and maybe it's a
multi-pitch roof. That lower part might be a covered

I was given a drawing, produced by a very large solar

the roof by several feet.

Notice how the array hangs out over the lawn for several
feet. Is there anyway that this is a legitimate way to
mount modules?
Thanks,
