Old Solar: 1980 Barnraised Solar Air Heater

[JustAn0bserver]

You are using 2 4x8 panels to heat from the kitchen to living room, and have to dump heat outside? What temp outside when interior is too hot? Whats inside the panel, black painted sheet steel; Pop cans making a pipe; Dryer air venting? Pop cans cut in half?

What kind of fan ? can a thermosatat turn the fan off when the rooms hot?

What is the panel made of? Why didnt the building do the entire upstairs? It would not look bad if it went from one side to the other.

Need more info
