[RE-wrenches] Snow Guards

[AE Solar]

Wrenchers

We have a 100 kW roof mount system where we are going to need to use snow
guards in the array. We are in the northeast (ground snow loads of 40 psf
at the site). Pitch is about 4:12. I was looking at the Snow Dog by Alpine
SnowGuards
<https://alpinesnowguards.com/roof-type/solar-panels/snow-dog-blk>. The one
thing that struck me is the wording*:*


*"there may be times and conditions where snow accumulates to depths
greater than 6”. If this happens, it is the responsibility of the building
owner to clear the excess accumulation. This will ensure structural
integrity of the solar array racking system and the building structure."  *

Getting 6" is common here (or at least it used to be), and in no reality
will the building owner clear snow off their array after a storm. I'm
wondering what you all do for snow guards. My engineer would make sure the
building structure could handle the additional loads caused by slowing the
shedding of the snow, but should I be concerned about the integrity of the
racking and also of the frames of the solar panels? Is there another
product worth looking into?

Thanks for any thoughts.
