Abstract
Solar collectors have flat plate-like foil tubes with permeable interlayers with lattice structure surfaces bonded to the foils of the tube. Several tubes with insulating backing are seam bonded together to form a sheet for covering a roof. Heat transfer medium flows from inlets into a space along one side of the tube, through the permeable interlayer into a space along the other side of the tube and through an outlet. The structure is thin, light, inexpensive and easy to install. Flow of medium which covers substantially all of a surface may be precisely controlled. Temperature of medium in the collectors may be maintained only slightly higher than temperatures throughout the system.
