Lars,
Yes, the only way you can even consider an install like this is a pole
mount, with a steep tilt in the winter to shed most of the snow. It would help
to know if the place will be used in the winter or summer and how big of an
array in KW or Sq Ft. Customer would have to understand that you cannot
guarantee it...there are some combinations of wind-snow-temp-moisture that make
snow cling to anything. If this is permitted, start dropping off cookies to an
engineer.

Subject: [RE-wrenches] Extreme snow load ground mount?
Wrenches,
I have a fun one for you. We have a couple of potential clients who live in
the high Sierra with a 420 LB design snow load. After hunting around, not even
a three rail system comes close with any module I can find, so now I'm looking
for a pole top that will dump the snow, and still handle 120 mph winds. Any
ideas? I would just say sorry, no solar for you,but like many of you I love a
challenge.
