[RE-wrenches] Fwd: Re: Cantilevered array

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 wrap-around porch.

I was given a drawing, produced by a very large solar company, showing the
array cantilevered over the edge of 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,
