Todd, Wrenches;
Todd's reply finally got me to reply too. I also deal with systems at
high latitudes, and those with the potential of very deep snow.
With Edmonton AB at 53-1/2 degrees north latitude, I don't see an issue
with a fixed lat + 15deg winter tilt -- when the sun does come out, the
array will shed accumulated snow and ice quickly. If the sun isn't out,
the point is moot. Just be sure to get the bottom of the array high
enough off the ground.

Snow removal never seems to be an issue as in the winter the panels are
at a steep enough angle to shed any buildup. Around the Mount Shasta (we
got 6' in 3 days last winter) the only problem I have encountered is
when there is so much snow so that when the slide off the modules builds
up a pile tall enough to meet the bottom of the array, no more will
slide. It then needs to be manually removed. This is why my pole mounts
typically have the bottom edge of the array at maximum winter tilt at
least 6' off the ground.
