That is definitely not going to be easier or cheaper.

They covered most of the parking lots with solar cells a few years back at nearby Michigan State. The economics weren't there, but as a friend who worked there pointed out they viewed it as research.

It's great that when it snows you don't get nearly as much of the white stuff on your vehicle. But when it snows energy production slows to a crawl. We have a lot of snowy days a third of the year.

  • I live in a fairly snowy area. The panels here are steeply angled. Tends to slide off.

    Same reason metal roofs are becoming popular in the area recently.

  • I wonder if there’s any situation where running heaters to keep the panels clear ends up with positive electricity generation. If nothing else it would help after the fact.

    • I think I'd go with bifacial panels, which can absorb light from their back sides as well as the front. Snow would be a concern at higher latitude, so the panels would be tilted, and if one row were covered with snow it would tend to scatter sunlight toward the back of the row in from of it. Most of the scattered light still ends up as heat which would tend to melt the snow.
