Bear in mind that snow is a pretty good insulator. After all, igloos are viable housing for some people and many animals hibernate in burrows under the snow. This means that in the winter the snow should stay on the roof. Assuming the weight isn't an issue and the house is sufficiently insulating that it doesn't melt it, then you would actually prefer this. Above the arctic circle this isn't much of a problem for illumination because it's dark all day anyway (typically you get a brief twilight period). https://nsidc.org/cryosphere/snow/science/characteristics.html https://nsidc.org/cryosphere/snow/science/characteristics.ht... Solardome can produce double glazed systems as well, but presumably single glazing is a lot cheaper. http://www.solardome.co.uk/domestic/dome-uses/domestic-self-build/ http://www.solardome.co.uk/domestic/dome-uses/domestic-self-...
