this Blake - seems to me you
need a platform type rack that has a tilt-up set of legs.<br>
<br>
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>
<br>
It's beefy strong - no aluminum - just might work with heavy snow.<br>

<br>
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>
<br>
Just a thought - hope it helps!<br>
<br>

dir="ltr">Hi all, <div><br></div><div>I think there's a lot of
experience on this list with PV in snowy regions.</div><div><br></div><div>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><br></div><div>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><br></div><div>To further paint the
picture, here are some more details and constraints:</div><div><br></div><div>-
System size: 23kW (likely 48 Silfab 490 mods)</div><div>- Must be
ground mount (beautiful very tall trees completely surrounding all roof
options)</div><div>- Must be relatively low profile, visually. Pole
mount not an option</div><div>- Ideally one clean rectangular array 4x12
mods (13' x 90') or two 4x6 arrays (13' x 45')</div><div>- Array tilt:
10-15 deg (summer use only, must be low-profile)</div><div><br></div><div>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><br></div><div>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><br></div><div>(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><br></div><div>Thanks in
advance for any suggestions, ideas, things you've tried that haven't
worked, etc!!</div><div><br></div><div>Best,</div><div>Blake</div><div><br></div><div>--
