Abstract
A panel is secured to the roof of a building in spaced relation with the roof so that a flow space for air is defined between the panel and the roof. The upper surface of the panel is defined by a series of channels whose side walls are formed with a concave-convex shape to cause solar radiation to reflect back and forth between opposing side walls a substantial number of times and thereby cause more energy to be absorbed by the panel for the purpose of heating the air in the flow space.
