A method of making a solar collector panel comprises the steps of applying a quantity of solvent to one face of a synthetic foam sheet to form a pattern of solvent stripes on said face, allowing the applied solvent to etch a pattern of grooves having highly irregular surfaces, painting the surfaces of the grooves exposed by the action of the solvent with light-absorbing coloring matter, and securing a light-transmitting cover sheet to the remaining portions of said face. The cover sheet, when secured, conforms to the shape of the face prior to the solvent application step, whereby the grooves and the cover sheet together form channels for the flow of a heat transfer fluid such as water or air.

The method of making a solar collector panel comprising the steps of providing a solidified sheet of foam material, forming on the face of said sheet a predetermined pattern of grooves sufficiently deep and wide to accommodate the turbulent flow of a supply of warm air for a portion of a building, in which the groove formation step is characterized by the application of a quantity of solvent to one face of the foam sheet in said predetermined pattern and the formation, by the action of the solvent, of irregular open pockets in the surfaces of said grooves, said open pockets being larger than the cells of the foam material, causing the surfaces of the grooves exposed by the action of the solvent to have a light-absorbing color, and securing a light-transmitting cover sheet to the remaining portions of said face, said cover sheet, when secured, conforming in shape substantially to the shape of the face prior to the groove formation step, whereby said grooves and said cover sheet together form channels for the turbulent flow of warm air.
