That's pretty cool. No pictures at the moment here, but I have not seen that behavior. So far, we have only gotten about 1.5" here (and probably not much more before it changes over to mixed/rain) and the roof is evenly covered in snow. Also a 34 degree slope, which might be less than yours (but always hard to tell from photos.)
It's that stuff you all drive over to Lake Tahoe to see.
I noticed earlier this year there was a (facetious?) discussion on a website about heating the tiles so the snow did not accumulate. I emailed the roofing company, the tesla installer and called customer service to see how they deal with this is snowier environs. Will post responses.
Update 1: roofing company says not their issue. he wondered if Tesla had snow guards for the edge of the roof like you would for a slate roof. perhaps one of the other two people I contacted will have info. He did say, incidentally, that because the roof sits up so high, it is likely the case that the snow flies right over the gutter. not sure about that, but it does get pretty far from the house, so maybe.
Hopefully it mostly does, though they installed wider gutters for us to catch more rain coming off the roof, which also might catch the snow. I can see some snow was caught in the gutters (with the gutter guards, it sticks up) but it could just be the bits that got left behind the main avalanche.
That could be part of it, though you would hope somebody brought it up (maybe when they were visiting Buffalo to discuss manufacturing.) But this might be the first snow for any significant number of v3 installs if most of them from 2019 were in central/southern CA (and not around Tahoe.) It will be interesting to see if we get any reports from folks between Philadelphia and Boston, where the storm is supposed to have bigger impacts.
