Daylight cellar as a solar collector?
I have a 28×36 daylight foundation with a 2ft knee wall on the south facing 28′ gable end. It is in the lakes region of NH. I am using floor trusses so I can leave the south gable unsupported on the basement level. I am considering banking that entire wall with recycled slider glazings and painting my cellar floor black. Then cutting registers in my 2×6 spruce floor above to let all that free heat flow on up to the living space.
I may bust up the cellar floor first to insulate it and make sure there is good radon abatement as well. It is 15 years old.
