Our Solar in the Winter

I am taking a course designing solar water heaters.  Based on the azimuth of your house related to south, and the angle of the collectors, and shading, and tables giving us our average amount of solar thru the year, we can calculate the square footage of collectors required to heat our water during the months of the year.  But I have not yet seen 0 solar collected in the winter months, which is what happens when your collectors are covered with snow.

Snow at our house this year from January thru February.  My design would put collectors on the right upper side of the house, to keep the snow off the collectors.
