How do you deal with freezing rain, or crusty snow that can't be brushed off?

Been reading this thread the last couple days here and there and noticed that my panels did exactly what was described here. The bottom 2 110's are series together, but then the middle 2 are in parallel together and then in series with the top 220. Top 3 group in parallel with bottom 2 group. Those seem to have heated the bottom 2 panels, a happy little accident in design, since the bottom panels are most likely to have water and ice shed onto them from the top panels

Would it make sense to install blocking diodes for the parallel strings in the summer and remove them in winter? It would be nice to have a way to flip back and forth as needed but I don't see a very feasible way that wouldn't be cost/efficiency prohibitive.

Jeff mentioned an ice scraper to clear the panels. We use one on the truck windows but they are glass. Aren't most solar panels some sort of plastic? Wouldn't an ice scraper damage them?

Shouldnt be.
Fixed panels should be glass.
