Time Taken To Melt 2m of Snow

How long would it take sunlight to melt 2 meters (thick) of snow on a mountainside ? Assume that the snow is 50% snow and 50% air, and that the only the sun does any melting (not a good assumption, I knw, but lets do only one thing at a time here). Let the angle of the sun be such that 1000 watts per square meter is incident, but 90% of this light is reflected.

Q = mL
Here, solar power used to melt snow = 0.1*1000 W per sq m = 100 W/sq m
Consider 1 sq m of area on mountainside.
