Snow Shedding and Photovoltaics

When Alex and I built our net-zero-energy house in Seattle, we didn't have to worry much about snow. Seattle gets just under 6 inches of snow per winter. The Methow Valley couldn't be more different. Unlike mild Seattle, it is a place of extremes: extremely hot in the winter, very cold in the winter, and lots of snow—56 inches average per year.
