solar heating storage questions
The size of your panels and the solar insolation for your area determines the average output of the panels, and the avg. heating req'mt for a house is 2 to 10 BTU per sq. ft. per heating degree day.
The heat storage capacity, i.e. the specific heat, is determined by how many sunless days you need to get through.
I've seen uninsulated stone structures in German houses built around an oven for smoothing out the day/night temp. differences. Possibly they occupied two cubic yards, but the whole of houses in Germany is designed to take advantage of heat storage.
