Yeah, I agree. I have the advantage of living in a subtropical climate, which seems like less of an advantage when the dengue season hits, but the 3400W heat pump my wife and I bought last year does a fine job of heating our 18m² bedroom—and, far more importantly, cooling it when it's +35° outside. You, by contrast, have apparently bought a palace somewhere closer to Antarctica.
200m² of solar PV can only provide about 45kW peak anyway, and on the roof under two meters of snow it would provide roughly zero. One of the advantages of vertical panels like Joey Hess's system discussed here the other day is that they don't necessarily get snowed on, and in some orientations they produce the most energy in the winter. But without enough insulation there's a limit to what you can do. This was apparently a major reason for hanging tapestries in castles older than yours.
Every solar setup ten years from now is going to look exotic by our current standards. Think about automobiles before and after the Model T, or shipping before and after the steam locomotive.
If I was contemplating heating a mansion on Hoth with 2000 amps of low-voltage DC from solar panels, I don't think I would want it connected to a single busbar. I think I'd want it in 5–40 separate circuits to limit the risks from possible short circuits.
