Snow doesn't really matter if you remove it.

And solar cells work way better if it is cold due to silicon having a lower resistance at lower temperatures.

So it's not all bad if it is not overly dark.

Also, if the modules are put in at high angle, up to vertical, they work better in winter when the Sun is low in the sky, and snow does not accumulate. In the summer one can even grow things between them. If the modules are bifacial, light scattered off the snow or sky behind them can be captured on the back surface.

But.. someone has to go out and remove that snow, unless they have something like the Starlink dishes, but I question the reliability of that in such a cold environment. It might end up costing more to keep the panels clean than the energy they produce.

"You periodically have to remove some snow" is a reality for basically everything in Wisconsin. Stuff still seems to get built there.
True, but are they solar powered? I love solar and want to see it literally everywhere, but think they could have chosen a better spot. I hope it works, very well.
