It would seem to me w/ the # of proposed modules you look at a motorized tilt option. There are companies, that design & build this type of rack for commercial apps. they would be able to scale down something that would address your needs.

<div style="" text="#000000" class="">Coming back to
this Blake - seems to me you
need a platform type rack that has a tilt-up set of legs.<br class="">
<br class="">
The Nuance Osprey is such a rack - though I think they only go up to 35º
but I think it could be easily adapted. They use Earth Anchors but can
also be mounted to sonotubes or even ground screws.<br class="">
<br class="">
It's beefy strong - no aluminum - just might work with heavy snow.<br class="">

It's possible having two in portrait makes for too high a vertical but
perhaps using 60 cell modules instead of 72 might make it workable.<br class="">
<br class="">
Just a thought - hope it helps!<br class="">

<meta http-equiv="content-type" content="text/html; charset=utf-8" class=""><div dir="ltr" class="">Hi all, <div class=""><br class=""></div><div class="">I think there's a lot of
experience on this list with PV in snowy regions.</div><div class=""><br class=""></div><div class="">I'm
wondering if anyone has ideas and/or specific hardware/racking systems
to allow for easy "stowing" (in vertical or near-vertical position) or
"seasonal removal" of the ground mount PV modules for the winter (snow)
season? Or ideas for a completely different approach to solving the
challenge I'm facing?</div><div class=""><br class=""></div><div class="">I'm planning a new
off-grid system in the Sierra (around 6000') for a small commercial
community center facility. The facility is accessible and in use only
during the summer months. So, I want to optimize production for the
summer, and also avoid having the array destroyed by the heavy Sierra
snow during the winter. </div><div class=""><br class=""></div><div class="">To further paint the
picture, here are some more details and constraints:</div><div class=""><br class=""></div><div class="">-
System size: 23kW (likely 48 Silfab 490 mods)</div><div class="">- Must be
ground mount (beautiful very tall trees completely surrounding all roof
options)</div><div class="">- Must be relatively low profile, visually. Pole
mount not an option</div><div class="">- Ideally one clean rectangular array 4x12
mods (13' x 90') or two 4x6 arrays (13' x 45')</div><div class="">- Array tilt:
10-15 deg (summer use only, must be low-profile)</div><div class=""><br class=""></div><div class="">There
is a caretaker who has a seasonal crew, and could be trained to "stow"
the array each season as long as that process is relatively
straightforward. </div><div class=""><br class=""></div><div class="">At one end of the spectrum,
it could be as simple as disconnecting and un-installing all of the
modules to store them in a stack underneath the nearby deck for the
winter. I'd like to think there might be a more "elegant" solution (and
less labor intensive, and less wear and tear on the modules over the
years). I wondered if there's a clever way to "drop" the modules to a
near-vertical orientation so they could remain in place during the
winter (some kind of hinge at the top and release at the bottom). I
guess this might require individual rows of modules instead of one large
array.</div><div class=""><br class=""></div><div class="">(As a bonus, I'd like to keep about
four mods (out of the 48) operational through the winter for battery
maintenance and a few incidental loads. These could be vertically
mounted on the south side of one of the buildings, above the typical
snow drift level, for example.)</div><div class=""><br class=""></div><div class="">Thanks in
advance for any suggestions, ideas, things you've tried that haven't
worked, etc!!</div><div class=""><br class=""></div><div class="">Best,</div><div class="">Blake</div><div class=""><br class=""></div><div class="">--
