I agree, its disheartening to see the collection available in winter. I can get roughly .75 kWh/(d*m^2). As it is based on my usage last winter I use ~130 kWh of heat per day in the worst of winter. That means I'd need 1850 sq ft of collector! Or, I could improve the house to loose less heat which is a much more viable and worth while idea.
